Abstract

The invention relates to a natural gas drain valve capable of draining water continuously. The natural gas drain valve is composed of a valve body and double valve elements. The large valve element is mounted in a cavity of the valve body through a guide rail. When the large valve element floats, separated liquid is drained from a separated liquid outlet through drain holes of the guide rail. A small drain function module is in a normally open state when a large drain function module works, and the small drain function module can remove accumulated water generated when the drain valve is out of operation. The drain quantity of the drain valve is adjusted automatically, and continuous draining can be achieved, so that the production safety of a gas field and stable operation of equipment are guaranteed.

Description

technical field [0001] The invention relates to a continuous drainage natural gas trap, which belongs to the technical field of gas field exploitation equipment. Background technique [0002] In the gas field production process, the automatic discharge of the separated liquid in the natural gas gas-liquid separator is an important part of the gas field production process. [0003] Regarding the design of natural gas traps, there are many mature structures: [0004] Patent CN203615046U discloses a natural gas trap, which changes the original design of the flow channel into an "L"-shaped flow channel composed of flow channel A and flow channel B, which relieves the leakage during the drainage process. It reduces the erosion of the seal by the medium and prolongs the overall service life of the trap. [0005] Patent CN202252808U provides a high-pressure natural gas trap, which is mainly composed of a trap body, a liquid inlet pipe installed on the trap body, a gas return pipe...
