Description

A kind of two-position-five-way solenoid valve
Technical field
The utility model relates to Pneumatic Control Technology field, particularly a kind of two-position-five-way solenoid valve.
Background technique
Existing two-position-five-way solenoid valve utilizes spring force to make valve core reset when commutating and resetting more, " two five-way valves ", the patent No. that are 201120338256.5 as the patent No. are " two-position-five-way solenoid valve " of 201420375993.6 etc., the structure of this valve is somewhat complicated, and spring easily gets rusty by erosion medium resistance, affects valve core reset speed.In actual applications, often there is the faults such as valve core seal ring wearing and tearing, the fracture of electromagnetic coil lighting outlet, off-line in solenoid valve, affects solenoid valve working life.In a word, the structure of existing solenoid valve haves much room for improvement, and reliability has much room for improvement.
Summary of the invention
The utility model is the above-mentioned deficiency in order to solve existing for prior art, provide a kind of simple for structure, commutating speed is fast, sealing reliability good, long service life, to install, the two-position-five-way solenoid valve of easy-to-connect simultaneously.
The utility model realizes by the following technical solutions for solving the problems of the technologies described above:
A kind of two-position-five-way solenoid valve, comprises valve body, bonnet, pilot head component, spool.Cavity before described valve body and described pilot head component are formed, have secondary piston in described front cavity, described secondary piston and pilot head component form ante-chamber; Described valve body and described bonnet form rear chamber, back piston is had in described rear chamber, described back piston and bonnet form back cavity, described back cavity is communicated with suction port in described valve body by the rear gas circuit on described bonnet, and described ante-chamber sagittal plane sum secondary piston diameter is larger than described back cavity sagittal plane sum back piston diameter respectively.
Described pilot head component, comprise gas control lid, cover plate, iron core sleeve, dynamic iron core, spring, static iron core, electromagnetic coil, trim ring stud, trim ring nut, terminal box, plug wire base, debugging stud, described gas control covers and arranges first gas port, gas control mouth, front gas circuit, described static iron core is fixed on described iron core sleeve upper end, described dynamic iron core can be axially movable in described iron core sleeve, and make iron core one end block up in gas control mouth under the action of the spring.
When described electromagnetic coil is not energized, described dynamic iron core blocks described gas control mouth under the action of the spring, now because described back cavity is communicated with suction port in described valve body by the rear gas circuit on described bonnet, therefore back piston pushes spool toward moving left under air inlet pressure effect, when described electromagnetic coil energising, described dynamic iron core overcomes described spring force and static iron core adhesive, open described gas control mouth, described ante-chamber is by described first gas port, described gas control mouth, described front gas circuit communicates with suction port in described valve body, described secondary piston pushes described spool and to turn right mobile trend under suction pressure effect, because secondary piston diameter described in described ante-chamber sagittal plane sum is larger than back piston diameter described in described back cavity sagittal plane sum respectively, so in same pressure situation, the thrust that described secondary piston acts on described spool is greater than the thrust that described back piston acts on described spool, finally make described spool toward moving right.When described electromagnetic coil power-off, described back piston pushes described spool again toward moving left under air inlet pressure effect, so makes described spool move back and forth, realizes commutation control.
Working principle of the present utility model is: when the solenoid is activated, the secondary piston of ante-chamber and the back piston of back cavity, according to: (P is that air pressure is strong to F=P × S, F is piston thrust, and S is that piston cross-section amasss) theory relation, in the strong situation of same pressure, piston thrust is directly proportional to piston cross-section is long-pending, because secondary piston diameter is larger than back piston diameter, thus it is poor to produce thrust, therefore spool is moved right and realizes commutation.
Described dynamic iron core is fixedly mounted with sealing gasket A and sealing gasket B, to strengthen the sealing of described dynamic iron core to described gas control mouth.
Described static iron core, trim ring stud, trim ring nut three arrange through hole, to avoid the airtight space that is made up of described iron core sleeve and described static iron core, described dynamic iron core and to produce air pressure, affect the adhesive of described static iron core and described dynamic iron core.
Described terminal box is fixed on electromagnetic coil shell side, and arranges plug wire base, makes electromagnetic coil lighting outlet substitute direct lead wire with extraneous with plug Placement like this, avoids the fault such as wire breaking, off-line, simultaneously easy-to-operat.
Described spool coordinates with valve body and lengthens, and to increase spool mobile range, increases solenoid valve flow, wear ring A and wear ring B is housed on described spool simultaneously, to prevent the ring wear on described spool, improves sealing reliability.
The beneficial effect that the utility model has is: electromagnetic valve structure is succinct, and soon, cushioning effect is obvious for commutating speed, and working flow is large, and sealing reliability improves, and working life extends, simultaneously installation, easy-to-connect.
