SLNF-35-shear-lever safety valve with an overview of use: SLNF-35-shear-lever safety valve for domestic 3NB-900 type, 3NB-1000 type, SL3NB-1300 type, SL3NB-1600 type, the continental United States Love Musi Ke-F-1000's, FB-1300 type, FB-1600 oil-drilling mud, used to connect the appropriate way, can also be used to 588KW (800HP) more than other types of security restrictions pressure pump system to protect the pump And exchange high-pressure pipe, hoses, drilling of security. The safety agency to cut use of lever pressure control system, the structure has a simple, accurate, secure, and other advantages.
Technical parameters:
1、the safety pin diameter Φ6.7mm
2、rated the greatest pressure 34.3MPa (350kgf/cm2).

And the installation of Notes
1, the valve design for the flange connection, the pressure relief safety valve pipeline, directly into the mud pool to minimize bending.
2, at the same time does not permit insertion of two or more than the safety pin.
3, the replacement of the safety pin, cover to cover in a timely manner to prevent vibration so that the pin off.
4, on a regular basis in between the piston and cylinder liner and other activities between the coated pieces of grease to prevent the adhesion, corrosion caused by the failure of safety performance and instability.
5, the safety pin to force the replacement of one per week.
