Multifunctional integrated solenoid valve

Abstract

The invention discloses a multifunctional integrated solenoid valve. The multifunctional integrated solenoid valve comprises a solenoid valve body, a solenoid valve cover, a water inlet, a combinationcoil, a return spring, a movable iron core, front surface membrane and an anti-blocking spring; a water outlet end of the solenoid valve body is connected with a constant-pressure constant-flow device; a water outlet end of the constant-pressure constant-flow device is connected with a vacuum breaker; a flow sensor is arranged between the solenoid valve body and the constant-pressure constant-flow device; the vacuum breaker comprises a shell and a water outlet; a cover is arranged at the top of the shell; a safe pressure relief sealing assembly which moves up and down is arranged between theshell and the cover; the safe pressure relief sealing assembly comprises an inner plug rod, a supporting sleeve, a safe pressure relief spring, a broken opening positioning ring, a check membrane anda vacuum breaking membrane; and a safe pressure relief opening is formed in the cover. The multifunctional integrated solenoid valve has a compact structure, convenience and reliability in assemblingand high operating stability, so that the functions are complete and the performance is ensured; moreover, the vacuum breaker is more concise in assembling; a positioning effect is good; and a safe pressure relief effect and a siphon preventing effect are better.

Description

technical field [0001] The invention relates to a valve, in particular to a multifunctional integrated electromagnetic valve. Background technique [0002] At present, in order to improve the various performances of solenoid valves, valve auxiliary components such as constant pressure and constant current devices, flow sensors or vacuum breakers are often integrated on the solenoid valves. However, due to structural and assembly reasons, the solenoid valves currently on the market It is difficult to integrate the constant pressure and constant current device, flow sensor and vacuum breaker on the solenoid valve, which makes its functions not comprehensive enough. Even if they are all integrated together, the structure will be complicated, the assembly will be troublesome, and the operation stability will not be guaranteed; Moreover, although the existing vacuum breaker integrated on the solenoid valve can maintain the pressure balance of the solenoid valve and prevent the va...

[0002] At present, in order to improve the various performances of solenoid valves, valve auxiliary components such as constant pressure and constant current devices, flow sensors or vacuum breakers are often integrated on the solenoid valves. However, due to structural and assembly reasons, the solenoid valves currently on the market It is difficult to integrate the constant pressure and constant current device, flow sensor and vacuum breaker on the solenoid valve, which makes its functions not comprehensive enough. Even if they are all integrated together, the structure will be complicated, the assembly will be troublesome, and the operation stability will not be guaranteed; Moreover, although the existing vacuum breaker integrated on the solenoid valve can maintain the pressure balance of the solenoid valve and prevent the valve from siphoning, it still needs to be tightened after the vacuum breaker rod is inserted into the housing, so the assembly is not simple enough, and Poor positioning of breaches, resulting in no guarantee of safe pressure relief and siphon prevention
