FET (Forum Energy Technologies) is a global company, serving the oil, natural gas, industrial, and renewable energy industries. FET provides value-added solutions that increase the safety and efficiency of energy exploration and production. We are an environmentally and socially responsible company headquartered in Houston, TX with manufacturing, distribution, and service facilities strategically located throughout the world.

As far as similarities go, this is where it ends because a driller responsibility requires skills such as "cdl," "preventative maintenance," "safety policies," and "geotechnical." Whereas a rotary operator is skilled in "customer specifications," "ran," "computer system," and "cnc." So if you"re looking for what truly separates the two careers, you"ve found it.

A Directional Driller specializes in drilling wells at different angles for better sources. They operate a variety of tools and machinery, follow guidelines, and conduct measurements and assessments to ensure quality and efficiency. There are also instances when they must produce progress and evaluation reports, maintain documentation, and develop maintenance strategies for the equipment. Directional Drillers must maintain an active communication line with co-workers, all while adhering to the company"s safety policies and workplace regulations.

While some skills are similar in these professions, other skills aren"t so similar. For example, several resumes showed us that driller responsibilities requires skills like "preventative maintenance," "safety policies," "safety procedures," and "routine maintenance." But a drilling rig operator might use skills, such as, "osha," "minor maintenance," "cathodic protection," and "cranes."

Some important key differences between the two careers are a few of the skills necessary to fulfill responsibilities. Some examples from driller resumes include skills like "cdl," "preventative maintenance," "safety policies," and "geotechnical," whereas a drill instructor might be skilled in "combat," "direct supervision," "platoon," and "core values. "

Even though a few skill sets overlap, there are some differences that are important to note. For one, a driller might have more use for skills like "preventative maintenance," "safety policies," "geotechnical," and "cpr." Meanwhile, some directional drillers might include skills like "directional drill," "survey data," "well reports," and "mud motors" on their resume.

In U.S. Pat. No. 4,187,059 to Parker, there is disclosed a valve guide construction of an intake valve for use in large multiplex pumps. Reference is made to this previous patent for further background of this invention. As pointed out by Parker, it is desirable that the poppet valve stem in large triplex pumps be axially aligned vertically while lateral support is provided for the poppet valves.

It is necessary that the intake valve in such a multiplex pump have the inner valve stem portion guided within a valve guide located inside the flow area of the pump fluid end. The valve guide must be removable from the fluid end for repairs or replacement of the valve member, and at the same time the valve guide must be easily placed within the fluid end and oriented to provide rigid, dependable valve guiding. Reference is made to U.S. Pat. No. 4,468,174 for further background of a multiplex pump suitable for helicopter transportation.

In a multiplex pump there is limited space for working on the fluid end of the pump. Provision must be made for removing the discharge valve vertically upward, and removing the suction valve rearwardly from the fluid end. The tremendous pressures developed within the fluid end of a multiplex pump requires that there be a minimum of sharp corners and drilled and threaded holes because of stress risers. It would therefore be desirable to have an improved fluid end for a multiplex pump that incorporated a minimum number of stress risers therein so that the fluid end could be built of a minimum size and weight as compared to fluid ends that must necessarily be made massive due to the numerous threaded holes and sharp edges that result in the unwanted stress risers.

Two Roughnecks require several hours of time in order to replace the intake valve assembly of most prior art multiplex pumps. Therefore, it would be desirable to be able to more rapidly service the intake check valve of a triplex mud pump in order to reduce the down time required for field repairs.

The present invention contemplates improvements in the fluid end of a multiplex pump by the provision of a valve guide bracket that enables access to an intake valve assembly in a manner to allow the valve to be removed rearwardly from the fluid end in opposition to the reciprocating piston, and which vertically aligns the valve stem and places the valve assembly within the variable chamber of the fluid end of the pump.

This invention discloses a valve guide adaptor for a check valve of a reciprocating pump. The improved valve guide adaptor brings about a new method of replacing a check valve in a mud pump. The apparatus of the present invention is for use on a reciprocating pump device having a check valve seated in a passageway formed in the main body of the fluid end of the pump, with there being an access port formed into the main body and arranged perpendicular to the passageway. A valve guide adaptor is seated in the access port and supports a yoke. A bracket having a valve guide thereon is pivotally attached to the yoke and can be pivoted from perpendicular relationship respective to the yoke into a position that forms an obtuse angle therebetween. When the yoke is operatively mounted to the adaptor, the guide is positioned in axial aligned relationship with the check valve seat. Accordingly, the adaptor is mounted in the access port, the valve stem of the valve element is placed within the valve guide of the bracket, the yoke is attached to the adaptor, thereby assembling the apparatus for operation.

Accordingly, a primary object of the present invention is the provision of a new combination of a valve guide bracket assembly by which a check valve of a reciprocating pump can be readily serviced in a new and unusual manner.

Another object of this invention is to provide a combination check valve assembly and valve guide assembly for use in conjunction with fluid pumps of the reciprocating type which enables the valve assembly to rapidly be replaced.

A further object of this invention is to provide a guide valve bracket for a reciprocating pump that enables the valve assembly of the pump to be removed and replaced in an efficient manner.

A still further object of this invention is the provision of an improved valve guide bracket for the fluid end of a triplex mud pump which enables the intake valve assembly to be field serviced in a novel manner.

In FIG. 1 of the drawings, there is disclosed a reciprocating pump 8, as for example a model H-700-B- Triplex Mud Pump manufactured by OIME, Inc. of Odessa, Texas. The mud pump 8 has a power end 9 and a fluid end assembly 10. Power effected at the power end 9 forces high pressure drilling fluid to flow through the fluid end 10. The fluid end of the mud pump has a main body 12 interconnected to a manifold assembly (not shown) for receiving mud from a mud pit (not shown) and forcing the mud to flow into a drill string (not shown). Triplex mud pumps, mud pits, and drill strings are well known to those skilled in the art and while the present invention is discussed in conjunction with a mud pump, it is contemplated that this invention can also advantageously be used on most any reciprocating pump having some of the problems solved by the present a invention.

In FIG. 2, the main body 12 is seen to have a plurality of tension bolts 14 by which the main body 12 is connected to the end of the cylinder of the pump 8. A threaded flange 16 and 17 is bolted onto the main body and provides a threaded surface for accepting nuts 18 and 19. The main body is provided with the illustrated inlet and outlet passageways within which there is appropriately mounted the illustrated intake valve assembly 20 and outlet valve assembly 21.

In FIG. 3, together with other figures of the drawings, it will be noted that the pin 28 hinges the bracket 24 and yoke 26 together and has opposed marginal ends seated in opposed pockets 68 (FIG. 5) so that the valve spring 44 urges the bracket 24 of FIG. 3 to be pivoted in a clockwise direction about the pin. This action is resisted by the recess 31 and lip 30 formed on the edge of the window 70 and the end of the yoke 26. Accordingly, the stop means 35 and 36 maintain the bracket and yoke perpendicular to one another due to the compressive force of the valve spring, while the moment arm between the pin 28 and the lip 31 prevent the yoke from turning clockwise. The blind flange 18 provides a sealed separator plate which abuttingly engages the face 66 of the valve guide adaptor plate 22. The nut 18 seen in FIG. 2 is threadedly made up within the threaded flange 16 and forces the adaptor plate shoulder against the shoulder of the access port. This maintains the components of the novel valve guide bracket assembly and the components of the valve assembly in assembled relationship during operation of the mud pump. When it comes time to replace any part of the valve assembly, one workman can easily accomplish a field repair as follows:

A tool bar 76 is used to remove nut 18, and thereafter the workman grasps the handle of the blind flange 18" and removes the flange from the access port. Next the tool bar 76 is extended through the window 70, through the port hole 32, and into abutting engagement with the ledge 48. The ledge 48 prevents the tool bar 76 from damaging other components of the pump and gives the workman a definite feel for the free end of the bracket 24. Next the bracket 24 is rotated in the direction of arrow 52 against compression spring 44. This relaxes the force on the pin 28 and lip 31 so that the recess 30 can be slipped downward free of the lip 31 as the pin 28 travels vertically downward within the opposed pockets 68 of the adaptor. Next, the pressure on the bracket is relaxed until the spring 44 is fully extended. The bar 76 is withdrawn, the bracket and yoke rotated into the configuration of FIG. 8, the bracket 24 lifted free of the valve stem, whereupon the bracket, pin, and yoke are removed through the window 70 of the adaptor. Next, the guide adaptor 22 can be removed from the access port, and then the valve spring, valve element, and valve seat can be removed and either serviced or replaced as may be required.

One skilled in the art, having digested this entire disclosure, will appreciate that assembly of the apparatus is carried out by first placing the valve seat 25 in proper position within the intake passageway in the illustrated manner of FIG. 2. Next, the valve and valve spring are seated within the valve seat. The yoke and bracket along with the pin 28 are assembled and the adaptor is placed in proper seated position within the access passageway. The bracket is extended through the window of the adaptor and the valve guide is next aligned with the valve stem. The yoke is rotated counterclockwise so that a bar 76 can be extended through hole 32 and into engagement with the ledge 48 of the bracket 24. At this time, it is only necessary to pick up on the end of the bar so that the spring 44 is compressed as the lip 30 slides under the recess 31 as the opposed marginal ends of the pin 28 slid vertically upward within the opposed pockets 68. The separator plate 18 is placed against the adaptor and the nut 18 securely made up to the pump is put back into operation.
