Problems solved by technology

[0002] The existing pressure solenoid valve pushes the valve body to the through hole through the connection of the electromagnetic force, and seals the liquid or gas to block the flow; The pressure solenoid valve with this structure has very high requirements on the size of the valve body and the valve body sealing ring, the life is short, the production is difficult, and the cost is high.
At the same time, the valve body of the pressure solenoid valve with this structure must add a sealing structure of the silicone ring. After long-term or multi-frequency use, the valve body sealing ring will be damaged and lose the sealing effect.
There are requirements for the temperature, corrosion and purity of liquid or gas. Liquid or gas with high temperature, strong corrosion and impurities will accelerate the damage of valve body seals

Abstract

The invention discloses a pressure electromagnetic valve, which comprises an electromagnetic valve body, a valve body, a fixing upper cover, a sealing gasket and a fixing lower cover. A plurality of installation holes are formed in two side surfaces of the electromagnetic valve body and two side surfaces of the fixing upper cover; the electromagnetic valve body is arranged in the fixing upper cover and fixed through screws; the valve body penetrates through the electromagnetic valve body; a reset spring is arranged at the upper part of the valve body; the sealing gasket is arranged between thefixing upper cover and the fixing lower cover; the fixing upper cover and the fixing lower cover are fixed through screws; the fixing lower cover comprises a fixing lower cover body, a liquid / air inlet channel and a liquid / air outlet channel; the liquid / air inlet channel and the liquid / air outlet channel are fixedly connected with the fixing lower cover body; a holding cavity is arranged in the fixing lower cover body; a liquid / air outlet of the liquid / air inlet channel stretches into the holding cavity; and the liquid / air inlet channel and the liquid / air outlet channel communicate through the holding cavity. According to the pressure electromagnetic valve provided by the invention, an application field and an application range of the pressure electromagnetic valve are greatly enlarged, and the service life of the pressure electromagnetic valve is prolonged.

Description

technical field [0001] The invention relates to a solenoid valve, in particular to a pressure solenoid valve. Background technique [0002] The existing pressure solenoid valve pushes the valve body to the through hole through the connection of the electromagnetic force, and seals the liquid or gas to block the flow; The pressure solenoid valve with this structure has very high requirements on the size of the valve body and the sealing ring of the valve body, the service life is short, the production is difficult, and the cost is high. At the same time, the valve body of the pressure solenoid valve with this structure must have a sealing structure of a silicone ring. After long-term or multi-frequency use, the valve body sealing ring will be damaged and lose its sealing effect. There are requirements for the temperature, corrosion and purity of liquid or gas. Liquid or gas with high temperature, strong corrosion and impurities will accelerate the damage of valve body seals....
