Integrated gas injection micro-exhaust valve

Abstract

The invention discloses an integrated gas injection micro-exhaust valve. The integrated gas injection micro-exhaust valve comprises a protective cover, the bottom end of the protective cover is connected with a gas injection valve body through a bolt, a guiding shaft is installed in the protective cover, a limiting block is connected to the top of the guiding shaft through a bolt, and a spring isconnected to the bottom end of the limiting block; and a gas injection valve cover is connected to the top end of the gas injection valve body, a micro-exhaust valve seat is connected to the position,below the guiding shaft, of the gas injection valve cover, a gas injection valve element is connected to the bottom end of the gas injection valve cover, and the bottom end of the gas injection valveelement is connected with a micro-exhaust ball basket through a bolt. The gas injection micro-exhaust valve adopts an integrated structure and is composed of a gas inlet part and a micro-exhaust partlocated in the valve body. The gas injection micro-exhaust valve is simple in structural design, reliable in work and durable, the starting pressure of negative pressure gas suction is determined through the spring, the position of the limiting block can be adjusted through double nuts on the upper portion so that the stroke of the spring can be controlled to achieve the effect that the gas supplementing pressure can be adjusted, meanwhile, the spring is not in water, and spring failure caused by water erosion does not need to be worried about.

Description

Technical field[0001]The invention relates to the technical field of water supply and drainage, and is specifically an integrated gas injection micro-exhaust valve.Background technique[0002]Valves are pipeline accessories used to open and close pipelines, control flow, adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are the control components in the fluid conveying system. They have the functions of cut-off, regulation, diversion, prevention of reverse flow, voltage stabilization, diversion or overflow and pressure relief. The valves used in fluid control systems range from the simplest cut-off valves to extremely complex The various valves used in the automatic control system of the company have many varieties and specifications. The valves can be used to control the flow of various types of fluids such as air, water, steam...
