Abstract

The invention relates to an underwater hydraulic valve internal and external pressure test system, which comprises a high-pressure cabin, a sealed cabin temperature control system, a valve hydraulic system, a valve pressurization system and a data integration and monitoring system, wherein the whole high-pressure cabin is arranged in the sealed cabin temperature control system; and the valve hydraulic system is connected with a hydraulic valve to be tested in the hyperbaric chamber through a hydraulic oil pipeline, and the valve pressurization system is connected with the hydraulic valve to be tested in the hyperbaric chamber through a high-pressure pipeline. The underwater hydraulic valve internal and external pressure test system can simulate the normal working state of water supply or ventilation of an underwater hydraulic valve in a deepwater environment for the underwater valve; and the system is widely suitable for simulating a deep-sea high-pressure low-temperature environment, performing internal and external pressure test and function test on the underwater hydraulic valve at the same time, and performing data acquisition and monitoring.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to an underwater hydraulic valve internal and external pressure testing system and an experimental method. Background technique [0002] With land resources increasingly scarce, the ocean will become one of the most important areas of research. Subsea valves are key components of underwater facilities in marine engineering. With the continuous advancement of deepwater technology, the demand for underwater facilities, especially underwater valves, is gradually increasing. For a long time, the underwater valve market has been occupied by foreign manufacturers. In order to enhance the domestic underwater equipment manufacturing capabilities, reduce costs and shorten the delivery cycle, the localization of underwater valves is imperative. Carrying out underwater valve testing is to meet the needs of product quality inspection under the new situation, and it plays an important technic...
