Abstract
The invention relates to a mechanism of a sealed electromagnetic valve. An inlet and outlet joint sealing ring is sleeved at the position of an inlet and outlet joint; the inlet and outlet joint is screwed into a threaded hole of a valve body; a return spring is arranged in a valve element sleeve; then a valve element is arranged in the valve element sleeve; valve opening and closing rubber is simultaneously fixed at the head part of the valve element; a valve element sleeve sealing ring is sleeved at the position of the valve element sleeve; the valve element sleeve is simultaneously screwed in a hole corresponding to the valve body; a valve cover is correctly arranged on the upper surface of the valve body; an electromagnetic coil is arranged on the excircle of the valve element element; and finally, an overhaul screw is arranged. When the overhaul screw and the valve body are installed, the reliable seal needs to be ensured.
Description
Technical field
The present invention relates to a kind of mechanism of solenoid valve, particularly a kind of mechanism of sealed electrical magnet valve.Belong to the Automation Elements technical field.
Background technique
Solenoid valve all is through the diverse location of solenoid controlled spool in valve body on structure and principle at present, the various switch motions of realization valve; Because spool is after the use of last time, the precise decreasing of its cooperation is leaked easily; So the solenoid valve that uses at present exists complex structure; Make trouble, cost is higher, the defective of leaking easily.
Summary of the invention
The objective of the invention is to: a kind of mechanism of sealed electrical magnet valve is provided, overcome existing electromagnetic valve structure complicated, make trouble, cost is higher, the defective of leaking easily.
The present invention realizes that the technological scheme that above-mentioned purpose adopts is: a kind of mechanism of sealed electrical magnet valve; It is with importing and exporting the joint sealing snare at the position of importing and exporting joint; And be screwed into the import and export joint in the tapped hole of valve body, the Returnning spring of in valve core housing, packing into the spool of then packing into is fixed on valve opening and closing rubber the head of spool simultaneously, the valve core housing seal ring is enclosed within the position of valve core housing; Be screwed into valve core housing in the pairing hole of valve body simultaneously; The valve gap correct installation above valve body, is installed electromagnetic coil and loaded onto at last when overhauling screw maintenance screw and valve body installation on the cylindrical of valve core housing, should guarantee reliable sealing.
Working principle of the present invention is: after the electromagnetic coil energising, the electromagnetic force that is produced is inhaled back spool, and the valve opening and closing rubber that spool just drives on it is open state by blocking the joint channel status of importing and exporting joint; And under the situation of electromagnetic coil dead electricity; Then spool drives the valve opening and closing rubber of its end under the effect of spring, and the passage of importing and exporting joint is blocked; Different electromagnetic coil energising and powering-off state just realize importing and exporting the different break-make situation between the joint.
Beneficial effect: the present invention has simple in structure, and is easy to manufacture, lower-cost characteristics, effectively overcome existing electromagnetic valve structure complicated, make trouble, cost is higher, the defective of leaking easily.
