Pneumatic plug valve features

Pneumatic Plug Valve Introduction: Pneumatic Plug Valve is a plug with a through hole as the opening and closing pieces, through the plug body and stem rotation to achieve the valve opening and closing action. Plug valve structure is simple, quick opening and closing, fluid resistance is small, in recent years as the history of the first people to adopt one of the valves, not only no longer replaced by the valve and other types of valves, but the market presents an increasingly hot trend. The characteristics of the pneumatic plug valve: 1. The valve inlet and outlet end of the window is designed to double channel groove seal ring structure, the tap in the rotation process, the sealing pressure between the sealing pair is gradually changing pressure until it reaches the fully open or fully closed position When sufficient seal pressure is generated, the seal pair achieves zero leakage. 2. Double groove seal ring PTFE liner can be made in the valve body does not produce a stable displacement, but also absorb the temperature changes caused by the liner caused by micro deformation, while the bushing and cock strong wipe effect, and Improve the service life of the sealing surface. 3. The whole sealing process can be approximated as the pressure in the pipeline has nothing to do. 4. PTFE bushing, according to the use of temperature and working medium with different materials filler, good lubrication, long life.

Drilling BOP And Control System

During oil drilling, it is installed on the wellhead casing head to control high-pressure oil, gas, and water blowout devices. When the oil and gas pressure in the well is high, the blowout preventer can close the wellhead (shut down). When the heavy mud is pressed into the drill pipe, there is a four-way under the ram, which can replace the mud invaded by gas, increase the pressure of the liquid column in the well, and suppress the ejection of high-pressure oil and gas.
Its types are divided into ordinary blowout preventer, universal blowout preventer and rotary blowout preventer. The universal blowout preventer can be activated in emergency situations to deal with any size of drilling tools and empty wells; the rotary blowout preventer can realize the blowout and drilling operation. In deep well drilling, in addition to two ordinary blowout preventers, universal blowout preventers and rotary blowout preventers are often added, so that three or four combinations are installed at the wellhead.
Annular Blow-out Preventer Annular Blow-out Preventer is usually equipped with a large gate with a ram-type blowout preventer. During operation, a sealed annular space is formed between the pipe string and the wellbore. When there is a pipe string in the well, it can also be separated The well is closed, but it will not work after several times of use, and long-term shut-in use is not allowed.
