Problems solved by technology

[0004] The object of the present invention is to provide a cut-off valve mechanism for an integrated gas injector assembly to solve the problem that the existing gas injector assembly proposed in the background technology uses a cut-off valve to control the gas during the delivery process. It is easy to cause excessive local gas pressure, which affects the service life of the structure, and it is easy to cause the instability of the seal. When the gas is in circulation, due to the existence of the cut-off valve, the transmission is uneven, which affects the stability of subsequent ignition and other issues.

Abstract

The invention discloses a stop valve mechanism for an integrated fuel gas injector assembly, relates to the technical field of valve bodies, and solves the problems that when a stop valve is used for controlling in the fuel gas conveying process of an existing fuel gas injector assembly, local fuel gas pressure is likely to be too large, the service life of the structure is affected, sealing is likely to be unstable, and the service life of the structure is affected. And due to the existence of a stop valve, the fuel gas is unevenly conveyed during circulation, and the stability of subsequent ignition is affected. The stop valve mechanism for the integrated fuel gas injector assembly comprises an assembly shell, a dispersion gas guide mechanism is installed on the inner side of the bottom end of the assembly shell, a sealing connection mechanism is installed on the upper end face of the dispersion gas guide mechanism, and a connection flow guide mechanism is installed on the inner side of the upper end of the sealing connection mechanism. Dispersion and pressure reduction flow guide operation is carried out during gas conveying, conveying stability can be effectively guaranteed, buffering can be conveniently carried out when gas is cut off, and the service life of the structure is prolonged.

Description

technical field [0001] The invention relates to the technical field of valve bodies, in particular to a cut-off valve mechanism for an integrated gas injector assembly. Background technique [0002] With the rapid development of social economy, there are more and more types of valve bodies, among which the cut-off valve is a kind of actuator in the automation system, which is composed of a multi-spring pneumatic film actuator or a floating piston actuator and a regulating valve. It has a wide range of uses and can be used to cut off gas, combustion air, cold air and flue gas, etc. In the application process of the gas injector assembly, it is necessary to use the shut-off valve to quickly cut off the gas. [0003] However, when the existing gas injector assembly uses a cut-off valve to control the gas delivery process, it is easy to cause excessive local gas pressure, which affects the service life of the structure, and easily causes the instability of the seal. The existen...
