Abstract

The invention relates to a connecting device fast detached and installed, in particular to a quick connector working under pressure. The quick connector working under pressure comprises a male connector and a female connector. The male connector comprises a plug connector body, a plug valve seat and a plug valve element. The female connector comprises a shell connector body, a shell valve seat and a shell valve element. The outer wall of the right side of the shell connector body is sleeved with an outer cover which is in threaded connection with the plug connector body. The quick connector working under pressure has the advantages that the plug and a socket are connected in a thread locking mode, and a product can be safer and more reliable to connect; an automatic pressure releasing device is arranged, and the requirement for operation under pressure can be met; a plurality of layers of anti-explosion high-temperature-resisting sealing rings and plastic washers are designed in a double sealing mode, and the higher using pressure and a higher using temperature range are ensured; environmentally-friendly chromeplate in a new technology is adopted, the higher rust protection performance and the higher corrosion resisting performance are achieved; the working temperature can reach -40 DEG C to 200 DEG C, and the number of times of plugging and using can reach up to 500,000.

Description

technical field [0001] The invention relates to a quick disassembly and assembly connection device, in particular to a quick joint working under pressure. Background technique [0002] Quick connectors include hydraulic quick connectors and various fluid quick connectors. It is a connection device that quickly connects or disconnects pipelines and realizes quick disassembly. Because the quick connector has a two-way check function and the pipeline is disconnected without leakage, it is widely used in the fields of petroleum, metallurgy, hydropower, construction machinery, ships, and electromechanical equipment. The design of the fluid channel is very important. Most of them use simple plugging to form a flow. The design of the flow channel is simple, but the sealing performance is not ideal. Contents of the invention [0003] In order to solve the technical problem of the unsatisfactory sealing performance of the simple design of the flow channel, the present invention pr...
