Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Bi-bit bi-pass high-frequency electromagnetic valve as shown in Figure 1, comprise valve body 1 and first guide assembly, valve body 1 is respectively equipped with suction port 11 and air outlet 12, the gas port 13 being communicated with suction port 11 and air outlet 12 is provided with in valve body 1, first guide assembly comprises sleeve pipe 21, dynamic iron core 22, static iron core 23 and coil block 24, dynamic iron core 22 is movably set with in sleeve pipe 21, be fixedly installed static iron core 23, sleeve pipe 21, air chamber A is formed between static iron core 23 and dynamic iron core 22, coil block 24 is fixed at the outside of sleeve pipe 21, the bottom of dynamic iron core 22 to be inserted in valve body 1 and to be fixedly connected with the Sealing 25 be sealed and matched with the input end of gas port 13, preferably, Sealing 25 adopts rubber material to make, the working life of rubber seal 25 is longer, plugging effect is better, Returnning spring 26 is provided with between Sealing 25 and static iron core 23.
The bottom of sleeve pipe 21 is extended with male threaded joint 27, and sleeve pipe 21 is threaded with valve body 1 by male threaded joint 27, compared with prior art, the utility model is welded and fixed without the need to adopting, install more convenient, and dismounting also more for convenience, is convenient to safeguard the utility model and overhaul.
The inner diameter of male threaded joint 27 is greater than the inner diameter of sleeve pipe 21, the bottom outer wall of dynamic iron core 22 is provided with undergauge inclined-plane 221, with the outer diameter making the lower end outer diameter of iron core 22 be less than its upper end, by arranging said structure, increase effectively the space near gas port 13 input end, make can gather more gas near gas port 13 input end, thus effectively ensure that when the servo-actuated iron core 22 of Sealing 25 departs from gas port 13, the output flow of air outlet 12 is comparatively large, serves the effect that large discharge exports.
The outer wall of dynamic iron core 22 is also provided with some gas guide grooves 222 be communicated with air chamber A by suction port 11, compared with prior art, the utility model without the need to arranging exhaust passage in static iron core 23, both the residual gas between dynamic iron core 22 and static iron core 23 had effectively been discharged, ensure that the sensitivity of dynamic iron core 22 action, also be beneficial to simultaneously and improve sealing effect of the present utility model, avoid the generation of gas leak phenomenon.
In order to improve tightness of the present utility model further, between threaded joints and valve body 1, be provided with seal ring 28.The boss 14 coordinated that to offset with Sealing 25 is provided with in valve body 1, boss 14 is provided with gas port 13 vertically, by arranging boss 14, when coil block 24 is not energized, Sealing 25 seals with boss 14 and contacts, thus effectively ensure that the plugging effect to gas port 13, make service behaviour of the present utility model more stable.
