Abstract
The utility model relates to a flame-proof two-way electromagnetic valve. The inside of a valve body is provided with a piston type valve core; an integral type priority valve is connected between the valve body and a flame-proof cassette; a valve core of the priority valve is linked with a movable iron core in the flame-proof cassette; the priority valve controls the communication of an inlet and an outlet of a priority hole, and the inlet and the outlet are respectively arranged on an inlet end and an outlet end of the valve body; the priority hole is communicated with a back cavity of the piston type valve core simultaneously; the piston type valve core and the valve core of the priority valve are respectively provided with a return spring; one side of the flame-proof cassette is also provided with a small end cover of the flame-proof cassette of a connecting terminal. The utility model overcomes the defects that the compressive strength of an ordinary flame-proof two-way electromagnetic valve is low, the corrosion resistance is low, and the wiring is not convenient. The utility model has the advantages of compact structure, good overpressure resistant property, good corrosion resistant property, and convenient connection.
Description
The utility model relates to a kind of flame proof two-way electromagnetic valve.
The flame proof two-way electromagnetic valve of known use, its main valve structural type is diaphragm type, the material of diaphragm is a nitrile butadiene rubber, the service behaviour instability, meeting make intensity reduce and tear along with increasing of working pressure.If in some special medias, use, as at No. 120 gasoline through the manipulating an of week, diaphragm will occur and bubble, out-of-flatness, deterioration phenomenon such as nonelastic, so that two-way electromagnetic valve can not normally open and close.Simultaneously, the same chamber of the tenminal block of this two-way electromagnetic valve and armored cassette, on-the-spot installation wiring is very inconvenient.
The purpose of this utility model is the above-mentioned deficiency that overcomes prior art, thereby provides a kind of being suitable for to use under hyperbaric environment, and corrosion resistance is strong, and the flame proof two-way electromagnetic valve of easy-to-connect safety is installed.
The utility model comprises valve body and armored cassette, be provided with electromagnet and movable core in the armored cassette, be provided with a piston valve core in the valve body, spool is provided with Returnning spring, be connected with the integrated type pilot valve between valve body and armored cassette, also be provided with spring on the spool of pilot valve and link with movable core, and control the import of the pilot hole that is separately positioned on valve body entrance point and outlet end and the connection of outlet, pilot hole is communicated with the back cavity of piston valve core simultaneously, side at armored cassette also is provided with the little end cap of armored cassette, is provided with tenminal block in the little end cap of armored cassette.
Below in conjunction with drawings and Examples detailed content of the present utility model is described.
Accompanying drawing is a structural representation of the present utility model.
As shown in the figure, the utility model comprises valve body 1 and armored cassette 2, in valve body 1, be provided with a piston valve core 5, piston valve core 5 is provided with Returnning spring 12, be provided with electromagnet 3 and movable core 4 in the armored cassette 2,2 of valve body 1 and armored cassettes are connected with integrated type pilot valve 6, also be provided with on the spool 7 of pilot valve spring 13 and with movable core 4 interlock, and control the import of the pilot hole 8 that is separately positioned on valve body 1 entrance point and outlet end and the connection of outlet, pilot hole 8 is communicated with the back cavity 9 of piston valve core 5 simultaneously, side at armored cassette 2 also is provided with armored cassette small end lid 10, is provided with tenminal block 11 in the armored cassette small end lid 10.During use, connect circuit on the tenminal block 11 in armored cassette small end lid 10 earlier, after the energising, the electromagnetic force that electromagnet 3 produces makes movable core 4 overcome the elastic force of weight own and spring 13 and promotes, the flap of pilot valve 6 is opened, the back cavity 9 of the import of pilot hole 8, outlet and piston valve core 5 is switched on, thereby produces pressure reduction between ante-chamber 14 in the valve body 1 and the back cavity 9, utilizes the main valve piston equilibrium principle and raises and open primary valve.Behind the deenergization, electromagnetic force disappears, and the pilot valve flap is closed the back cavity 9 of working medium from the outlet infiltration piston valve core 5 of pilot hole 8, and piston valve core 5 tends to balance, and each spring reset is closed primary valve.
The utility model has compact conformation by above-mentioned concrete structure, the compressive resistance height, The advantage of easy-to-connect safety is a kind of flame proof two-way electromagnetic valve that is worthy of popularization.
