downhole safety valve made in china

Subsurface Safety Valve TRSSSV is a kind of tubing retrievable safety valve which is controlled at the surface. It directly connects to the tubing string. There is a hydraulic control line connecting to the safety valve from the ground. While a certain amount of pressure is supplied through this control line to the safety valve, the valve remains open; while the pressure is released, the safety valve will close and the tubing pass is closed at the same time.

The TSS series subsurface safety valves are tubing retrievable surface controlled subsurface safety valves. Compared with the TS series, the safety valve features super slim outer diameter design. The control line connects the valve to the surface, and the pressurization from surface on the control line controls the opening and closing of the flapper. This series of products includes self-equalizing and non-equalizing types.

YKSLS series single line hydraulic control sliding sleeve is a downhole tool used for layered mining to realize oil sleeve annulus switch and flow regulation.

The RuiFeng"s model “TFCW” tubing-retrievable safety valve is a flapper-type, hydraulically operated TRSV installed in the production string. It is designed to shut in a well in case of an uncontrolled surface or subsurface event. The valve is held open by the hydraulic control pressure and remain open until the control pressure is released. The robust hydraulic piston provides a reliable control system and isolate the inner critical part from the well fluid. RuiFeng TFCW TRSV utilizes a metal-to-metal body joint and metal to metal flapper & seat to provide a superior well containment.

The RuiFeng TFCW TRSV can be permanently locked open by a lock-out tool, and establish a communication path between the TRSV hydraulic chamber and tubing string for a wireline retrievable insert valve.

The RuiFeng FTRN tubing retrievable safety valves are designed with single rod-piston actuation and flapper type closure mechanism. The valve is held open by the hydraulic control pressure and remain open until the control pressure is released. The non-elastomer piston seal with back-up system are provided for better dynamic and static seal.

If necessary, the RuiFeng TFRN TRSV can be permanently locked open by a lock-out tool, and an additional communication tool can establish communicated path between the TRSV hydraulic chamber and tubing string before installing a wireline-retrievable insert valve.

RuiFeng"s “TFRS” TRSV is a single rod piston, curved-flapper type, tubing retrievable safety valve engineered to provide a reliable operation and long-term life in a hostile environment.

The valve utilizes the non-elastomeric single piston actuator, metal to metal body joint, a rugged flapper-closure mechanism, centralizing system to provided 100% well containment when closed. For maximum reliability, the piston mechanism incorporates static metal to metal stop seals while the piston reaches full open and full close positions. The slim line curved flapper design is utilized to optimize OD and ID of the valve for maximal production rate and smaller casing size.

An industry-standard self-equalizing feature can be added to this valve. It allows the pressure drop before the flapper start to open and prevent flow directly across the critical MTM seal interface.

The RuiFeng TFRS TRSV can be permanently locked open by a lock-out tool, meanwhile a communication path will be established between the TRSV hydraulic chamber and tubing string to control a wireline retrievable insert valve.

Brief introduction: Down-hole safety valve is one type of control device for well liquid abnormal flow. It has self-balance structure, which could close automatically In emergency to control liquid flow in well. Self-balance structure is made by anti-corrosion material and guarantee to supply security in emergency, which could lower influence for integrity and reliability of safety valve.

Structure feature: Tubing retrievable butterfly type safety valve is open by hydraulic control pipeline, close by spring, hydraulic power, spring compression etc. Apply butterfly structure and surface pressure, hydraulic oil through pressure hydraulic control pipeline to hydraulic port till to floating piston, push piston to down movement and compress spring, open valve or ball valve. Safety valve keeps open as holding hydraulic pressure. Release hydraulic control pipeline pressure, spring tension push floating piston upward, valve flapper or valve ball is closed. Circulating port area of butterfly type safety valve is full size, which is suitable for high production oil & gas well by large flow.

Because of different of drive source, SSV can dividedinto Hydraulic safety valve and pneumatic valve ; With thermal and high voltage explosion-proof device ; Actuators and prepare two parts of the valve, standard interface, easy replacement and maintenance .

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.

（3）At the top of valve is equipped an electromagnet to open and another to close the valve. The actions of the mechanism and the electric appliance are separate and will not affect each other.

（2）Impulse safety valve shall be installed vertically and the lever shall be kept level. The clearance from the lever to both sides of guide fork shall be even.

（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.

2,The main safety valve shall be fastened upon the gallows, which sustains the back-seat force produced in the steam discharging process of the main safety valve.

3,The exhaust pipe shall contain a special gallows to prevent the force of its weight directly applying on the main safety valve. The connecting Lange At the lowest point of the exhaust pipe, water drainage shall be taken into consideration to avoid producing water hammer while discharging set between the main safety valve and exhaust pipe shall eliminate any extra stress.

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.

The Accu-Shear device opens and closes like a butterfly valve, and the pin is situated on the outside of the device which allows for easy and efficient replacement. The Accu-Shear pin is designed to break cleanly every time. During the manufacture process, every fifth pin is broken to insure the material or tolerance has not changed. Our Accu-Shear pins are less costly than our competitor’s pins and are easily replaced without needing to tear down the entire system.

Through innovative organic development and strategic acquisition, we have built a broad portfolio of ASME and API valves that services the demands of global drilling, production, pipeline, storage, transmission, and critical service applications.
