YD-5000a, YD-5000b and YD-5000c series spring reset safety valves provide protection for mud pump and mud manifold to ensure safer operation of drilling rig during drilling; Instead of shear safety valve, accurate control of mud pump pressure is realized through spring adjustment to avoid downhole accidents during pump shutdown.
YD-5000a, YD-5000b and YD-5000c series spring reset safety valves adopt integral piston structure and separated piston structure, with simple and beautiful appearance and convenient replacement of vulnerable parts; Manual reset can be realized without stopping the pump after opening sensitive and pressure relief; The pressurized fluid adopts built-in double protection to avoid the injury of other equipment and personnel caused by the overflow of high-pressure fluid in case of seal failure.
YD-5000a, YD-5000b and YD-5000c series spring reset safety valves, with a maximum working pressure of 5000PSI (34.5mpa), are high-pressure valves. The key parts on the valves are made of high-strength materials. The design, manufacture and test comply with relevant API specifications, with higher safety performance.
the outlet is connected with 3 "figure 1502 Union, which is fast and convenient without welding and bolt connection;
heavy bolts ensure better operation performance under high pressure;
the main seals are made of polyethylene and fluoropolymer;
internal coating design is adopted to improve anti-corrosion performance and product life;
the inlet is 3 "figure 1502 union or API standard 5000PSI flange connection, which is universal, safe and reliable;
no pressure bearing threaded connection, conforming to API specification;
the high-pressure liquid is sealed in a closed cavity composed of high-strength materials and seals. The valve body is not under pressure during operation. The safety valve realizes double-layer protection for the fluid to ensure the personal safety of on-site users;
7500psi static pressure test to ensure the safety and reliability of high voltage system;
standard type and sulfur resistant type (hydrogen sulfide) can more widely meet the different needs of users.
Working principle and structure:
YD-5000a, YD-5000b and YD-5000c series spring reset safety valves are composed of inlet flange or union, valve body, piston, reset handle, connecting rod, crank, spring, etc
YD-5000a, YD-5000b and YD-5000c series spring reset safety valves (hereinafter referred to as reset safety valves) adjust the opening pressure of the safety valve by adjusting the compression of the pressure regulating spring. The safety valve is indicated by a scale and pointer. When the pressure reaches the set pressure value, it can be opened automatically to realize the pressure relief function, Without stopping the drilling pump or stopping the drilling pump, force can be applied through the reset handle to close the safety valve again to realize the reset function.
Manual pressure relief device: YD-5000a, YD-5000b and YD-5000c series spring reset safety valves are equipped with manual pressure relief caps. When the safety valve needs to be opened, press the manual pressure relief cap by hand to enable the safety valve to realize the function of opening and pressure relief, and then reset through the reset handle to close the safety valve again to realize the reset function.
