Description

Technical Field

[0001] The utility model relates to the technical field of pump valve structures, in particular to a pump valve structure suitable for high-pressure environments. Background Art

[0002] The pump-valve structure is a critical link in the fluid system. It involves the connection and coordination between the pump and the valve to ensure that the fluid can flow smoothly, safely and efficiently. The design and implementation of the pump-valve connection need to consider multiple factors, including fluid properties, working pressure, temperature, medium corrosiveness, vibration, leakage risk and the overall performance requirements of the system. In short, the pump-valve connection is an indispensable part of the fluid system. Its design and implementation need to comprehensively consider multiple factors to ensure the safe, reliable and efficient operation of the system.

[0003] Under high-pressure environments, the pump and valve structures of existing technologies need to withstand extremely high pressures, and some traditional materials may not be able to meet this requirement, resulting in deformation, rupture and other failures of the pump and valve under high pressure. If the pressure-bearing structure design of the pump and valve is unreasonable, it will not be able to effectively disperse the pressure brought by the high-pressure fluid, resulting in local stress concentration, and then causing damage to the pump and valve. The sealing structure is the key to maintaining the sealing of the pump and valve under high-pressure environments. Uneven sealing surfaces and improper selection of sealing materials will cause leakage problems in the pump and valve under high pressure. Therefore, we need a pump and valve structure suitable for high-pressure environments. Utility Model Content
