Description

Valve pressure detection device and clamping structure Technical Field The utility model belongs to the technical field of detection devices, and particularly relates to a valve pressure detection device and a clamping structure. Background The valve pressure detecting device is a special device for testing the tightness, strength and performance of the valve under a specific pressure working condition. The core function of the valve is to detect whether the valve has leakage, deformation or functional failure by simulating the actual working condition pressure (liquid or gas). The clamping structure is a key component for connecting the valve and the detection device, and needs to adapt to different valve types and interface forms. The existing clamping structure is designed independently according to the sizes and interfaces of different valves, so that the clamp can clamp only one valve when the valve to be tested is clamped, a great deal of time and energy are consumed when the clamp is replaced, the detection efficiency is greatly reduced, and the novel structure is used for solving the problems. Disclosure of utility model Aiming at the defects in the prior art, the utility model aims to provide a valve pressure detection device and a clamping structure, and solves the problems in the prior art.
