Quick joint valve assembly with interlocking device

Abstract

The invention relates to a dry valve assembly with a quick joint, which consists of a male joint part with a valve and a female joint part with a valve, wherein the male joint part consists of a manual valve, a quick joint and a lock pin in starting and shutoff linkage with the valve; the female joint part consists of a valve capable of elastic automatic recovering and shutoff; and a pin hole matched with the lock pin on the male joint is formed in the female joint, the rotation of a valve rod drives the lock pin to move, so as to ensure that the quick joint is mounted in place and unified with the opening of the valve, and ensure the safety of the operation. The dry valve assembly overcomes the safety hazards of high possibility of mal-operation and fluid leakage due to the lack of effective safety protection design in the quick butt jointing and transferring operation of the fluid medium in the prior art. By adopting the design, the valve can't be opened when the quick joint is not yet butt jointed; the quick joint can't be cut off when the valve is not yet completely closed; and after the quick joint is disassembled, the leakage problem of the residual fluid medium at the joint is avoided. The design not only realizes the quick connection problem that the pipelines need to be frequently connected, but also ensures the safety of the joint of the transfer pipeline of toxic, inflammable and high-corrosive medium.

Description

technical field [0001] The invention relates to a valve assembly, in particular to a quick joint valve assembly with its own interlocking device. Background technique [0002] The safe and fast docking and transmission of dangerous media is a dangerous job that requires operators to be highly professional and responsible. The traditional fast docking operation of fluid medium is generally to connect the delivery pipe with quick connector and the valve with quick connector device for transportation. However, the design of the traditional valve quick connector device has the problem of leakage of residual medium at the joint and the problem that the operator forgets to close the valve and then disengages the quick connector. The existence of these problems has great potential safety hazards for the transportation of dangerous media. Once the above two problems occur, it will cause casualties, environmental pollution and economic losses. Contents of the invention [0003] T...
