Abstract

The invention relates to the technical field of choke valves, and discloses a choke valve for a subsea oil tree. Both the oil outlet pipe and the oil inlet pipe are connected with the valve body, and the top of the valve body is provided with a rotating disk, and the left side of the bottom of the rotating disk is fixedly connected with a valve stem. The present invention can make the oil and gas entering the interior of the fixed sleeve The leak plate falls into the inside of the anti-blocking ring, so that the impurities in the oil and gas can be filtered by the leak holes opened by the trapezoidal block, and the filtered oil and gas are discharged from the oil outlet pipe, avoiding the blockage of the oil outlet pipe by the impurities in the oil and gas, thus avoiding the blockage The problem of inconvenient cleaning occurs. By setting the connecting piece 1, the oil and gas can impact the baffle to make it rotate, and can drive the oil and gas to rotate and discharge inside the connecting piece 1, so that the impurities in the oil and gas can be concentrated when the connecting piece 1 rotates inside, so that the subsequent The filtering effect is better.

Description

technical field

[0001] The invention relates to the technical field of choke valves, in particular to a subsea Christmas tree choke valve. Background technique

[0002] A throttle valve is a valve that controls fluid flow by changing the throttling section or throttling length. A one-way throttle valve can be combined by connecting the throttle valve and the one-way valve in parallel. The throttle valve has no negative flow feedback function, and cannot compensate for the speed instability caused by the load change. Generally, it is only used for occasions where the load change is not large or the speed stability is not required.

[0003] During the use of the subsea Christmas tree throttle valve, impurities in the oil and gas will easily cause the valve port to block, so we propose a subsea Christmas tree throttle valve. SUMMARY OF THE INVENTION
