Detailed description of the invention
Fig. 1 is the cross-sectional view of the balanced type gas electromagnetic valve in the embodiment of the present invention.
Fig. 2 is the perspective view of seal cap in the embodiment of the present invention.
Specific embodiment
The present invention will be described in further detail below with reference to the embodiments of the drawings.
As depicted in figs. 1 and 2, the present invention in balanced type gas electromagnetic valve, including valve body 1, shell 2, electromagnetic coil 3,
Spool 4, seal cap 5 and elastic component 7.
Wherein valve body 1 uses valve body 1 in the prior art, has blast tube 11 in valve body 1, blast tube 11 is in valve body
Inlet and outlet 111 is formed on 1.Furthermore also have on the valve body 1 and export 111 opposite opening portions, shell 2 is then fixed to be connected
It connects in the opening portion position of valve body 1.
Electromagnetic coil 3 in the present embodiment uses 3 finished product of electromagnetic coil in the prior art, and electromagnetic coil 3 is arranged in shell
In body 2.In order to facilitate assembly, there is the mounting hole passed through for spool 4 on shell 2, extend forward on the front end face of electromagnetic coil 3
It is provided with a circle position-limited edge 31, position-limited edge 31, which can match, to be inserted in the mounting hole of shell 2.During 3 center of electromagnetic coil has
Heart hole, spool 4 are then threaded through in the center of electromagnetic coil 3, and the front end of spool 4 is protruded by the opening portion on valve body 1
In the blast tube 11 of valve body 1.
Limited post 6 is also connected on the rear end face of electromagnetic coil 3, limited post 6 protrudes into the centre bore in electromagnetic coil 3
It is interior, the blind hole that can be protruded into for limited post 6 is offered on the rear end face of spool 4.Elastic component 7 is arranged outside limited post 6, in the present embodiment
Elastic component 7 use spring.One end of spring is against on the connecting end surface of limited post 6, and the other end of spring is against the interior of blind hole
On end face.After being powered in electromagnetic coil 3, electromagnetic coil 3 can drive spool 4 to move backward, at this time 4 compressed spring of spool,
So that spring is in compress energy storage state.And after 3 power loss of electromagnetic coil, then electromagnetic coil 3 disappears to the driving force of spool 4,
Then under the elastic force effect of spring, spring forces spool 4 travels forward, and realizes automatically reseting for spool 4.
In order to guarantee the leakproofness between valve body 1 and spool 4, isolation board is provided between shell 2 and the joint face of valve body 1
8, which can be convenient the installation of the connection between shell 2 and valve body 1, and spool 4 is passed through from the isolation board 8.For convenience
The Matching installation of the isolation board 8, one week forward end of 8 inward flange of isolation board, which is convexly curved, to arch upward.Isolation board 8 and shell 2
Between be folded with sealing element, between avoiding spool 4 during back-and-forth motion between electromagnetic coil 3, shell 2 by sealing element
The case where gap leaks air, while it being also equipped with sealing element between isolation board 8 and valve body 1, it can effectively ensure that valve body 1 and spool
Leakproofness between 4.
Seal cap 5 has rubber material to be made, and has certain elasticity.The hollow setting of seal cap 5 in the present embodiment, this is close
There is cavity 51,5 cross section of seal cap in the present embodiment is trapezoidal, that is, has front end face, rear end face and connection in sealing cap 5
Inclined end face between front end face and rear end face.It is uniformly distributed on the inclined end face of seal cap 5 and offers at least three apertures
53.There is the hole penetrated for 4 front end of spool, the outer peripheral edge of the front end of spool 4 is radially convexly equipped with one on the rear end face of seal cap 5
Convex shoulder 41 is enclosed, the front end of spool 4 is connected in seal cap 5 by 41 activity of convex shoulder, and spool 4 can be in the cavity 51 of seal cap 5
Inside move along the longitudinal direction.Offer aperture 52 on the front end face of seal cap 5, spool 4 is being moved forward and backward relative to seal cap 5
It can open and block in the process the aperture 52 in seal cap 5.In order to guarantee sealing of the spool 4 to 5 front end aperture 52 of seal cap
Property, corresponding to the front end of spool 4, recess is provided with to match for spool 4 front end and be caught on the inner wall of 5 front end face of seal cap
Groove 54, i.e., after spool 4 travels forward relative to seal cap 5, all sealing is snapped into for 4 front end face of spool and 41 part of convex shoulder
In groove 54.
And spool 4 is able to drive seal cap 5 and moves forward and backward during back-and-forth motion, so that seal cap 5 is beaten
Open and block the outlet 111 of blast tube 11.When blocking the outlet of blast tube 11 111 in order to further ensure seal cap 5, sealing
Leakproofness between cap 5 and the outlet of blast tube 11 111, one week of the outlet 111 of blast tube 11, which is inwardly extended, one
All edges 112, recess is provided with the annular groove 55 for the matching insertion of edge 112 on the front end face of seal cap 5, i.e. seal cap 5 blocks
Behind the outlet of blast tube 11 111, then one week edge 112 of the outlet 111 of blast tube 11 is snapped onto just in annular groove 55, effectively
Improve the leakproofness between seal cap 5 and the outlet 111 of blast tube 11.
The working principle of the balanced type gas electromagnetic valve are as follows: logical for electromagnetic coil 3 when gas electromagnetic valve carries out drawing valve operation
Electricity pulls spool 4 to move backward, is firing since seal cap 5 blocks at this time under the action of the electromagnetic force that electromagnetic coil 3 generates
At the outlet 111 in gas channel 11, the back pressure of seal cap 5 is big at this time, then spool 4 is first in the cavity 51 of seal cap 5 relative to close
Sealing cap 5 moves backward, then spool 4 opens the closure to aperture 52 in seal cap 5, the combustion entered from 11 entrance of blast tube
The aperture 53 of gas self-sealing cap 5 enters in the cavity 51 of seal cap 5, and then flows through the aperture 52 of seal cap 5, so that seal cap
The pressure difference of 5 rear and front ends reduces.As spool 4 continues to move backward, when the convex shoulder 41 of spool 4 is against the rear end face of seal cap 5
After upper, spool 4 then pulls seal cap 5 to move backward, and since the pressure difference of 5 rear and front end of seal cap constantly reduces, then spool 4 drives
Seal cap 5 moves the opposite reduction of required active force, and spool 4 drives seal cap 5 to move back together, and then opens to blast tube 11
The closure of outlet 111.The process then draws valve success rate to get a promotion, and draw since the pressure difference of 5 rear and front end of seal cap reduces
The energy consumption needed during valve reduces.In this way, on the one hand light current valve can be configured by the balanced type gas electromagnetic valve, reduce
The manufacturing cost of gas electromagnetic valve.Also it is applied to the biggish blast tube 11 of gas flow simultaneously for the balanced type gas electromagnetic valve
Outlet 111 provides possibility.
After 3 power loss of electromagnetic coil, spool 4 then moves forward under the action of the spring, and the front end of spool 4 is also by seal cap
Aperture 52 on 5 blocks, the final outlet 111 for driving seal cap 5 to block blast tube 11, i.e. closure valve port.
