Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a seabed valve detector. Background Art

[0002] Subsea valve refers to the general term for all valves used in underwater pipelines. Subsea valves are mainly used in underwater manifolds and transmission pipelines of marine oil and gas projects. At the same time, underwater valves are also used in deep-sea submersibles. Subsea valves are mainly ball valves, flat gate valves, and check valves. The operation methods are mainly hydraulic and manual. The development of subsea valves needs to consider the impact of external pressure resistance on wall thickness, the impact of subsea working conditions on the external structure of the valve, subsea anti-corrosion coatings, electrode corrosion, etc., which requires not only a large number of personnel in software design and development for calculation and simulation, but also external pressure test chamber equipment, seawater corrosion test chamber and other special inspection and testing equipment.

[0003] Normally, external leakage of the valve body can be discovered through direct observation, while internal leakage of the valve body is difficult to detect directly. However, internal leakage of the valve body can easily cause serious harm. Therefore, it is necessary to regularly detect leakage of the valve body to ensure the normal operation of the system. However, the detection efficiency of the detector in the prior art is low, and it cannot be changed according to the size of the detected valve model. It is single and has poor stability when detecting the valve, which affects the detection accuracy. In addition, when fixing the valve, it is easy to cause wear to the valve, affecting the normal use of the valve in the later stage. Therefore, in order to solve the above problems, the utility model proposes a submarine valve detector. Utility Model Content

The hydraulic rod is extended and retracted to drive the fixing block to fix the subsea valve, thereby improving the stability of the device. The buffer block can reduce the wear on the valve body during the fixing process. The laser detector is driven by motor two to move for detection, thereby reducing the labor intensity of the staff and improving the detection accuracy of the detector.
