Description
Technical field
The present invention relates to Solenoid Valve Technology field, especially a kind of waste water solenoid valve preventing blocked primary orifice waste water.
Background technology
Throttle solenoid valve valve has throttling function, and in use, waste water hole path is easy Crystallization Plugging, influences just
It is often used.
China Patent No. is：201620374305.3, the applying date is the patent on April 19th, 2016, discloses one kind
Solenoid valve with scale removal mechanism, including valve body, valve rod, diaphragm and electromagnetic drive mechanism, electromagnetic drive mechanism driving stem edge
Valve rod is axial and flexible towards valve body, and diaphragm is fixedly installed on the other end of the valve rod with respect to electromagnetic drive mechanism and is located at valve body
It is interior, runner is provided in valve body, which is provided with flow inlet and outflow port, which sets between flow inlet and outflow port
Set it is opposite with diaphragm cross mouth, solenoid valve is provided with the waste water tunnel in parallel with mouth is crossed in runner, the waste water tunnel and
The end of flow inlet unicom is opposite with valve rod and is coaxially disposed, and the end of valve rod towards waste water tunnel is coaxially arranged with constriction,
Constriction stretches into waste water tunnel and along waste water outside waste water tunnel when electromagnetic drive mechanism drives diaphragm is close to cross mouth by valve rod
Channel moves axially；Constriction is moved to useless out of waste water tunnel when electromagnetic drive mechanism drives diaphragm is separate to cross mouth by valve rod
Outside aquaporin, between constriction and waste water tunnel inner peripheral surface exist for fluid by adjusting gap.In above-mentioned technical proposal, it is
It is stretched axially and towards valve body along valve rod by electromagnetic drive mechanism driving stem, when valve rod driving diaphragm is close crosses mouth, diaphragm
Constriction is driven to be inserted into waste water tunnel, flow can be flowed through from gap location is adjusted；When valve rod driving diaphragm is far from mouth is crossed, diaphragm band
Dynamic constriction removes waste water tunnel, and valve body is gradually opened, and the moment that constriction leaves waste water tunnel generates difference in flow, logical to waste water
Road inner peripheral surface generation is washed away, and to eliminate the dirt of waste water tunnel inner peripheral surface accumulation, solenoid valve is made to have the function of scale removal, however
Since waste water tunnel is directly to be opened on valve body, higher to the required precision of processing, the pressure of flow is larger, and flow is from useless
It will produce larger noise when aquaporin flows through.
