Air cylinder driven type high-pressure quick coupler

Abstract

The invention discloses an air cylinder driven type high-pressure quick coupler. After a male head is inserted into a female head, the male head and the female head can be connected in a locked mode through a male head outer groove and an embedded female head positioning steel ball, a female head sealing spring serves as an elastic element, force of the spring can act on a male head sealing body and a female head sealing body, and the sealing bodies in the female head and the male head interact with each other to compress the sealing spring to realize air channel communicating; and after the male head and the female head are disengaged from each other, the elastic force of the spring and the internal air pressure jointly act on the sealing bodies, and thus the end faces of the sealing bodies are in close contact with a shell to achieve self-sealing. Full automation of high-pressure fluid medium filling is achieved, the workload of operators is lowered, human-machine isolation in a high-pressure dangerous area is achieved truly, and the personal safety of workers is ensured.

Description

technical field [0001] The invention relates to the technical field of high-pressure gas filling, in particular to a cylinder-driven high-pressure quick-fit joint. Background technique [0002] High pressure quick connectors are widely used in the field of high pressure medium filling. However, the conventional high-pressure quick-release joints are all in the form of manual connection. The male part of the quick-release joint is generally fixed on the device to be filled, and the female part of the quick-release joint is installed on the gas filling hose, which requires manual on-site manual operation. The connection and disconnection of the female part and the male part of the quick connector. Conventional high-pressure quick-fit joints have the following disadvantages: The conventional high-pressure quick-fit joints with simple mechanical structures lack reliable indications of snap-in structural connections, which are likely to cause misoperations; the flow and operatio...

However, the conventional high-pressure quick-release joints are all in the form of manual connection. The male part of the quick-release joint is generally fixed on the device to be filled, and the female part of the quick-release joint is installed on the gas filling hose, which requires manual on-site manual operation. Connection and disconnection of the female part and the male part of the quick connector

Conventional high-pressure quick-fit joints have the following disadvantages: The conventional high-pressure quick-fit joints with simple mechanical structures lack reliable indications of snap-in structural connections, which are likely to cause misoperations; the flow and operation of high-pressure media always exist during gas filling and discharge. Operations such as filling, uncoupling, and discharge are highly dangerous, and errors in the operation process can easily cause accidents, and the man-machine cannot be separated, which is very dangerous
