The invention discloses a sea valve with a sampling function, relates to the technical field of sea valves, and solves the problems that a sea valve needs to be opened during sampling, and the sealing performance of the sea valve is reduced and leakage occurs due to long-time repeated operation. The sea valve with the sampling function comprises a valve body, wherein a connecting branch pipe is arranged on one side of the outer wall of the valve body, a control air cylinder is arranged on the outer side of the other end of the connecting branch pipe, a control valve element is arranged below the control air cylinder, a sampling power mechanism is fixedly installed on the inner wall of the valve body, and a sampling operation hole is formed in the other side of the outer wall of the valve body. By arranging the sampling operation hole, a sampling sealing mechanism, the sampling power mechanism, a sampling auxiliary mechanism and a sampling storage mechanism, sampling can be rapidly conducted from the interior of the sea valve, the sealing performance of the sea valve is not damaged, the operation is easy and rapid, and the working efficiency is effectively improved.
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 ...
