Utility model content

The utility model is overcomes above-mentioned drawback, there is provided a kind of electromagnetic valve body, be integrated with inlet, outlet outlet, reduce with The installation accuracy of the other assemblies of magnetic valve, product fraction defective is reduced, as a component of magnetic valve, because to installation essence The reduction of degree, the design technology of magnetic valve is set to require to reduce.

To reach above-mentioned purpose, the technical solution adopted in the utility model is：A kind of electromagnetic valve body, including the He of magnetic conduction frame 1 The core structure 2 being erected on magnetic conduction frame 1, in addition to copper coil 3, core structure 2 include being successively set in sleeve pipe 21 determining Iron core 22, dynamic iron core 23 and valve 24, flexible member 25 is provided between fixed core 22 and dynamic iron core, between dynamic iron core 23 and valve 24 Provided with plug 26, copper coil 3 is arranged on the outside of sleeve pipe 21 by coil brace 4, and is provided with coil on coil brace 4 and accesses Device 41, facilitate the access of copper coil 3, and valve 24 is provided with the first stomata 241 and the second stomata 242 so that magnetic valve Air inlet and gas outlet can be integrated on valve body, rather than being arranged on valve seat similar to traditional design；

Specifically, the ring of the first stomata 241 is located at the outside of valve 24, the second stomata 242 is arranged on the end of valve 24, also, First stomata 241 and the second stomata 242 can air admission hole and venthole each other, i.e., when the first stomata 241 is air admission hole, the second gas Hole 242 is then venthole, opposite, when the first stomata 241 is venthole, the second stomata 242 is then air admission hole, and this kind designs The installation accuracy of electromagnetic valve body and miscellaneous part, convenient operation can be reduced, while practicality can be lifted；

Further, magnetic conduction frame 1 is U-shaped three-dimensional frame, and valve 24 passes through a side guide pillar, and fixed core 22 is led through opposite side Post so that core structure 2 is hung on magnetic conduction frame 1；

Further, core structure 2 is additionally provided with sealing ring 27 in the outside of magnetic conduction frame 1, specifically, sealing ring 27 is arranged on two Place, it ensure that air-tightness when this structure coordinates with other modules；

Because above-mentioned technical proposal is used, the utility model has following advantages compared with prior art：

A part of the utility model as magnetic valve, be integrated with inlet, outlet outlet, reduce with magnetic valve its The installation accuracy of his component, product fraction defective is reduced, as a component of magnetic valve, because the reduction to installation accuracy, The design technology of magnetic valve is set to require to reduce, meanwhile, iron core and gas nozzle structure are integrated into a set tube module, are easier to reality Existing assembly precision between iron core and valve, while the Double seal ring structure in outside, it ensure that this structure coordinates with other modules When air-tightness.

Embodiment

Below in conjunction with the accompanying drawings and embodiment is further described to the utility model：

Embodiment：

A kind of electromagnetic valve body, as depicted in figs. 1 and 2, core structure 2 are connected to the top of magnetic conduction frame 1, and magnetic conduction frame 1 is U-shaped vertical Body frame, core structure 2 include fixed core 22, dynamic iron core 23 and the valve 24 being successively set in sleeve pipe 21, and valve 24 passes through U-shaped One side guide pillar of three-dimensional frame, the fixed core 22 on core structure 2 pass through another side guide pillar so that core structure 2 is hung on magnetic conduction On frame 1, copper coil 3 is arranged on the outside of sleeve pipe 21 by coil brace 4, and coil access device is provided with coil brace 4 41, facilitate the access of copper coil 3.

Above, valve 24 is provided with the first stomata 241 and the second stomata 242 so that the air inlet and outlet of magnetic valve Mouth is different from being integrated on valve body of traditional design, rather than is arranged on valve seat, specifically, the ring of the first stomata 241 is located at valve 24 outsides, the second stomata 242 is arranged on the end of valve 24, also, the first stomata 241 and the second stomata 242 can air inlets each other Hole and venthole, i.e., when the first stomata 241 is air admission hole, the second stomata 242 is then venthole, opposite, when the first stomata 241 For venthole when, the second stomata 242 is then air admission hole, and this kind is designed to reduce the installation essence of electromagnetic valve body and miscellaneous part Degree, convenient operation, while practicality can be lifted.

To solve airtight sex chromosome mosaicism during other modules cooperation of this structure, core structure 2 is additionally provided with close in the outside of magnetic conduction frame 1 Seal 27, specifically, sealing ring 27 is arranged at two, it ensure that air-tightness when this structure coordinates with other modules.

Operation principle of the present utility model is as follows：

Due to the effect of flexible member 25, valve body is usually in normally off, i.e. plug 26 is acted on valve 24 so that Gas circuit is in off state, and in real work, valve connection air compressor machine and work package, when valve body is powered, i.e. copper coil 3 On have the function of current, because of electromagnetic induction principle, dynamic iron core 23 then can principle valve 24, now plug 26 is away from valve 24, gas circuit Connect.

When the first stomata 241 on valve 24 is air admission hole, the second stomata 242 is then venthole, opposite, when first When stomata 241 is venthole, the second stomata 242 is then air admission hole.

And during valve body power-off, electromagnetic induction disappears, and flexible member 25 plays a part of reseting plate again so that valve body is in normal Closed state, now gas circuit disconnection.

The utility model is integrated with core structure and valve, less demanding to the assembly precision between iron core and valve, together When avoid this structure and magnetic valve other intermodules high assembly precision requirement.

For above-mentioned embodiment only to illustrate technical concepts and features of the present utility model, its object is to allow be familiar with this skill The people of art can understand content of the present utility model and implement according to this, can not limit the scope of protection of the utility model with this. All equivalent transformations done according to the utility model Spirit Essence or modification, should all cover the scope of protection of the utility model it It is interior.
