Abstract
The invention relates to an electromagnetic valve structure which is characterized in that a sealing ring for an inlet and outlet joint is sleeved in the proper position of an inlet and outlet joint, and the inlet and outlet joint is screwed into a corresponding threaded hole of a valve body; a return spring is arranged in a valve core sleeve, then a valve core is arranged in the valve core sleeve, and simultaneously, valve opening and closing rubber is fixed at the head of the valve core by using a proper method; a valve core sleeve sealing ring is sleeved in the correct position of the valve core sleeve, and simultaneously, the valve core sleeve is screwed into the hole corresponding to the valve body; a valve cover is correctly installed on the valve body; an electromagnetic coil is installed on the outer circumference of the valve core sleeve; and finally, overhaul screw nails are installed. When the overhaul screw nails and the valve body are installed, a reliable seal needs to be ensured.
Description
Technical field
The present invention relates to a kind of solenoid valve, particularly a kind of electromagnetic valve structure.Belong to integral automation Element Technology field.
Background technique
Solenoid valve is on structure and principle at present, all be by the diverse location of solenoid controlled spool in valve body, the various switch motions of realization valve, this solenoid valve is in order to realize the control of different fluid trends, in valve body and spool, have passage like the labyrinth of many different trends, so manufacturing is comparatively complicated, sealing between simultaneously this each passage of solenoid valve is by spool blocking and decontroling between the corresponding passway to be realized closing motion, because spool is after the use of last time, the precise decreasing of its cooperation, leak easily, so at present there is complex structure in the solenoid valve that uses, to make cumbersomely, cost is higher, especially owing to leak easily, be not suitable for place and other corresponding place uses taking place in vacuum.
Summary of the invention
The objective of the invention is to: provide a kind of simple in structure, easy to make, especially sealing effect is better, is not easy to leak, and is suitable for vacuum place and the employed a kind of electromagnetic valve structure of other particular field take place.
The present invention realizes that the technological scheme that above-mentioned purpose adopts is: a kind of electromagnetic valve structure, and it is by valve core housing, Returnning spring, the valve core housing seal ring, spool, valve opening and closing rubber is imported and exported the joint sealing circle.Import and export joint, valve body, the valve bonnet seal circle, valve gap, electromagnetic coil is formed.Be shaped on cavity in the middle of the described valve body, the hole of making the some quantity of a row in the outer symmetrical of valve body communicates with the valve inner cavity, be installed into outlet connection in the exhausting hole therein, import and export between joint and the valve body and seal with importing and exporting the joint sealing circle, in a round of the valve body of importing and exporting the joint opposing side, valve core housing is installed, the intermediate fabrication of valve core housing is by blind hole, the cavity of one end of blind hole opening in the middle of spool, bottom in blind hole is equipped with Returnning spring simultaneously, and Returnning spring heads on the spool that is installed in the blind hole, and the head of spool is embedded with valve opening and closing rubber, described in the above spool, with magnetic property preferably material make, valve core housing then adopts brass, red copper, or the non-magnetic material of aluminum alloy class makes, in order to avoid because of self producing magnetic spool is impacted.It is identical with the inner chamber of valve body also to have tapped hole on valve body, so that check and maintenance respective via situation, just often, is screwed into the maintenance screw in the tapped hole it is shut, the middle cavity of valve body and the hole of exterior valve gap and the sealing of valve bonnet seal circle.
Solenoid valve working principle recited above is: after the electromagnetic coil energising, the electromagnetic force that is produced sucks back spool, the valve opening and closing rubber that spool just drives on it is open state by the joint channel status that blocks import and export, 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 situations between the joint.
Beneficial effect: the present invention has simple in structure, easy to manufacture, the characteristics that Costco Wholesale is lower, especially the sealing mechanism of the connecting part of each part all is fixed sealing configuration, so be difficult for leaking, suit place and the tighter place use of other convection cells leakage control to take place in its vacuum.
Description of drawings
Accompanying drawing is a structure principle chart of the present invention.
Shown in the figure: 1, valve core housing; 2, Returnning spring; 3, valve core housing seal ring; 4, spool; 5, valve opening and closing rubber; 6, import and export the joint sealing circle; 7, import and export joint; 8, valve body; 9, valve bonnet seal circle; 10, valve gap; 11, electromagnetic coil; 12, maintenance screw.
Embodiment
The invention will be further described below in conjunction with drawings and Examples.
To import and export joint sealing circle (6) and be enclosed within the suitable position of importing and exporting joint (7), and import and export joint (7) is screwed in the respective threads hole of valve body (8), the Returnning spring (2) of packing in valve core housing (1) spool (4) of then packing into uses suitable method valve opening and closing rubber (5) to be fixed on the head of spool (4) simultaneously, valve core housing seal ring (3) is enclosed within the tram of valve core housing (1), simultaneously valve core housing (1) is screwed in the pairing hole of valve body (8), with valve gap (10) correct be installed to valve body (8) above, on the cylindrical of valve core housing, install electromagnetic coil (11) and load onto at last when overhauling screw (2) maintenance screw (2), should guarantee reliable sealing with valve body (8) installation.Its working principle is: after electromagnetic coil (11) energising, the electromagnetic force that is produced sucks back spool (4), the valve opening and closing rubber (5) that spool (4) just drives on it is open state by blocking the joint channel status of importing and exporting joint (7), and under the situation of electromagnetic coil (11) dead electricity, then spool (4) is under the effect of spring, drive the valve opening and closing rubber (5) of its end, the passage that to import and export joint (7) blocks, different electromagnetic coil (11) energising and powering-off state just realize importing and exporting the different break-make situations between the joint.
