Turbine fixed pneumatic ball valve standards is how to suppress

turbine fixed pneumatic ball valve in some artificial environment shell test and seal test process is as follows.
turbine fixed pneumatic ball valve features: the double block and discharge using floating spring preload to hold turbine pneumatic ball valve, pneumatic valve seat when the pneumatic valve in full open and close, under the condition of two different fluid blocking by upstream and downstream side of the pneumatic seat, pneumatic valve is emissions discharge of pneumatic valve body lumen retention effect.
turbine automatic pressure relief function fixed pneumatic ball valve: when the abnormal pressure is due to the temperature rise of pneumatic valve body cavity for medium, only the pneumatic seat function can achieve automatic pressure release, and completely don't need to pass the security pneumatic valve for pressure relief, which, when conveying liquid medium security is greatly increased.
fire safety structure: follow the API and APIFA specification requires that the design and manufacture of pneumatic valves, must have the function of fire safety is set up.
turbine fixed ball seal urgent on the rescue: when pneumatic seat in the fire or blockage of foreign bodies in the seal of accidental failure caused by injection of grease gun will quickly and greasing pneumatic valve is connected, it will in the shortest time make the pneumatic sealing seat sealing grease injection, and to a great extent, alleviate the leak.
reliable pneumatic stem seal box: low operating torque in the standard seal ring set, 'O' type sealing ring is designed on the packing gland, so that pneumatic stem seal reliability is greatly enhanced. Under the effect of graphite packing and sealing grease injection, once appear fire, the extent of the pneumatic valve stem leakage will be dropped to the lowest degree, and in pneumatic valve rod sliding bearing and thrust bearing, under the dual role of pneumatic valve will become quite simple and convenient operation.
turbine fixed pneumatic ball valve full size or reducing: all sizes of pneumatic valve flow aperture in the design and pipe diameter can keep the same size, so that the pipeline cleaning task becomes very simple, also can choose according to demand full size or reducing the use of structure.
pneumatic valve stem can be lengthened: for such as gas or in the city need to spread the specific requirements of the underground pipeline, pneumatic valve pneumatic valve rod can be extended to handle, so to meet customer demand. Flexible operation, turbine fixed pneumatic ball valve: use a small friction coefficient and good self-lubrication of pneumatic rod bearing seat and pneumatic valve, greatly reduced the pneumatic valve operating torque. So even in the case of the provided no sealing grease, is also a long-term mobility of pneumatic valve operation.
