Description

Technical Field

[0001] The utility model relates to the technical field of pump-valve connection, in particular to a leak-proof device for pump-valve connection. Background Technique

[0002] Pump-valve connection is a very crucial link in the fluid system. It involves the connection and cooperation between the pump and the valve to ensure the smooth, safe and efficient flow of the fluid. The design and implementation of pump-valve connection need to consider multiple factors, including fluid characteristics, working pressure, temperature, medium corrosiveness, vibration, leakage risk, and the overall performance requirements of the system, etc. In short, pump-valve connection is an indispensable part of the fluid system, and its design and implementation need to comprehensively consider multiple factors to ensure the safe, reliable and efficient operation of the system. Currently, when people install valve pumps on the market, leak-proof devices are often used.

[0003] When the existing leak-proof device for pump-valve connection is in use, the pump will generate vibrations during operation. These vibrations will cause the bolts to have small lateral movements. After a long time of accumulation, these small movements will overcome the friction between the threads and cause the bolts to gradually loosen. In some joints, due to stress concentration and microscopic plastic deformation, the surface under the bolts may become flat, thus eliminating the peaks and resulting in bolt loosening. The creep of the gasket is also an important factor. After the initial tightening, the gasket will start to relax due to the compressive force generated by the bolts, thereby affecting the fastening effect of the bolts. Therefore, we need a leak-proof device for pump-valve connection. Content of the Utility Model
