Abstract

The invention discloses a sea-sea valve with a sampling function, relates to the technical field of sea-sea valves, and solves the problem that the sea-sea valve needs to be opened when the sea-sea valve is sampled, and repeated operations for a long time will lead to a reduction in the sealing performance of the sea-sea valve and leakage. question. A submarine valve with a sampling function, comprising a valve main body, a connecting branch pipe is provided on one side of the outer wall of the valve main body, a control cylinder is provided outside the other end of the connecting branch pipe, and a control valve is provided below the control cylinder The inner wall of the valve main body is fixed with a sampling power mechanism, and the other side of the outer wall of the valve main body is provided with a sampling operation hole. The present invention is equipped with a sampling operation hole, a sampling sealing mechanism, a sampling power mechanism, a sampling auxiliary mechanism, and a sampling storage mechanism, which can quickly sample from the inside of the seabed valve without destroying the sealing performance of the seabed valve. The operation is simple, fast and effective. Improve work efficiency.

Description

technical field [0001] The invention relates to the technical field of seabed valves, in particular to a seabed valve with a sampling function. Background technique [0002] With the rapid development of social economy, submarine valve refers to the collective name of all valves applied to underwater pipelines. Submarine valves are mainly used in underwater manifolds and pipelines of offshore oil and gas projects. At the same time, underwater valves are still in deep sea. There are certain applications on submersibles. Submarine valves are mainly ball valves, flat gate valves, and check valves. The operation methods are mainly hydraulic, ROV operation, and manual operation (shallow water). [0003] However, the existing subsea valve needs to open the subsea valve when sampling the inside of the valve body. Repeated operation for a long time will lead to a decrease in the sealing performance of the subsea valve and leakage; therefore, it does not meet the existing needs, and ...
