mud pump pressure relief valves made in china

Since 2006, Envirovalve has been changing the game for safety relief valves. Our innovative designs for pressure relief valves have already made significant impacts on the industries we service. The most impactful of those designs has been our Accu-Shear Pin Device.

Our ASME certified Accu-Shear pressure relief devices have a revolutionary design that is different from other traditional Buckling Pin Devices and Valves like Rupture Pin, Buckling Pin, Rupture Disc and BPRV. The device does what its name implies; it shears or breaks the pin as opposed to compressing or bending the pin that you see in most pressure relief valves.

Our F series mud pump are designed and manufactured on the basis of American Emsco F series mud pump strictly according to America Petroleum Institution API 7K Standard. All of its expendable parts are interchangeable with any other spare parts produced according to API standard. Therefore it is easy to repair and maintain internationally .

F series mud pump are applicable to the requirement of high pump pressure in oilfield and high displacement technology of well drilling with its solid and compact structure,small volume and out-standing operation performance.

F series mud pump has a longer stroke and can be operated at a lower stroke, thus improved the water supplying performance effectively and extended the lifetime of expendable parts in the fluid end greatly. The suction pulsation dampener has an advanced structure which is reliable to use and can make the pump realize its best suction performance.

The power end of F series mud pump adapts combined lubricating system of forced lubrication and splash lubrication. Reliable to lubricate and increased the service life of power end.

This valve is used for power plant boilers, pressure containers, pressure and temperature reducing device and other facilities. It serves to prevent the pressure exceeding the highest allowable pres-sure value and ensure the safety of the device when working.

（1）The pressure of the disc is balanced through the lever and heavy hammer and the valve is ensured seal by moving the for ton of heavy hammer and changing the weight of heavy hammer to reach the required set pressure.

（4）A long distance between the leading pipe of the impulse safety valve and the inlet pipe of the main safety valve shall be kept. And the distance between the electric contact pressure meter and the inlet pipe of the main safety valve shall be no less than 5 times of the diameter of the inlet pipe, for feat that the validity of the mater and the impulse safety valve may be affected by the steam releasing process of the main safety valve.

This valve is used for power plant boilers, pressure containers, pressure and temperature reducing device and other facilities. It serves to present the pressure exceeding the highest allowable pres-sure value and ensure the safety of the device when working.

1,When the medium pressure rises to the set pressure, the in-pulse safety valve opens, and the medium in the impulse pipe enters into the piston chamber of the main safety valve from impulse pipe, forcing the piston to descend, and then the valve automatically open-s; when the impulse safety valve closes, the disc will slash automatically close.

Early boilers operating without one were vulnerable to accidental explosion.Vacuum safety valves (or combined pressure/vacuum safety valves) are utilized to prevent a tank from collapsing even though it is being emptied, or when cold rinse water can be used after hot CIP (clean-in-place) or SIP (sterilization-in-place) procedures.

The Model HPRV valve provides safety for a variety of pressure relief applications including but not limited to: mud, slurry, and fracing fluid relief. The valve relieves pressure to prevent pump, hose, and system damage on frac fluid systems – ideal for pulsating pressure. Use instead of nitrogen-assisted valves or ball & spring reset valves where you need greater accuracy and reliability. Our hydraulic fracturing and mud and slurry relief valve ranges are exceedingly popular in the Oil & Gas industry.

Pinch valves control the flow of fluids (liquid, gas or power) and provide a leak-proof seal when closed. They are cost-effective, simple to install and require little maintenance.

The valves are made up of a valve body and a cylindrical sleeve reinforced with natural or synthetic rubber. Typically in an open state, the valve is closed by the application of pressure between the valve body and the sleeve. This pressure is created by a fluid, usually compressed air,that crushes the sleeve in a particular direction, completely closing the valve.

Available in cast iron, aluminum and PVC materials, we offer a complete range of full-bore valves suitable for a range of applications:Acids: hydrochloric, nitric, sulfuric, hydrofluoric, etc.

An electrical detection system is usually installed (pressure switch or pressure sensor) to detect and stop the pump when a potentially damaging high paint pressure is reached. This could be due to an inadvertent closing of an outlet ball valve, paint filter blockage or paint line restriction.  The Pressure relief valve is a purely mechanical device and intended to complement the primary electrical safety device which must be installed.  The mechanical relief valve can be easily installed directly on the pump outlet manifold. Any relieved paint pressure is piped back into the mix tank.

The valve opens as a result of hydrostatic pressure outside the wall of a tank exceeding the inside pressure. The opening action allows water to flow into the tank thus equalizing pressure both inside and outside of the tank.Maintenance

Valves are to be mounted vertically only. Care should be taken to prevent damage to the seats when placing in form and pouring concrete. Cover and grate should be installed in the body, turned a quarter turn, and tested to be sure cover and grate cannot lift off body.Parts
