Abstract
The utility model provides a diaphragm type electromagnetic valve which comprises a cavity formed by assembling a valve seat and valve cover. The middle of the cavity is provided with a diaphragm; the valve cover, the diaphragm and the valve seat are assembled by screw nails; the upper part of the valve cover and the round plane of the lower end of a sleeve are welded or drawn into a whole; the upper part of the sleeve is matched and welded with an end enclosure; the sleeve is internally provided with a core iron; the inner hole of the upper part of the core iron is provided with a compression spring; and a pilot valve which is arranged at the lower part of the core iron and riveted with the diaphragm is connected with a tension spring. The diaphragm type electromagnetic valve is characterized in that the valve cover and the sleeve are combined into a whole. Because the diaphragm type electromagnetic valve does not have a screw nut connecting part and a sealing ring, and the valve cover is made by drawing a stainless steel sheet and welded with the sleeve into a whole, or the valve cover and the sleeve are directly drawn into a whole, the structure is relatively simple, the finishing machining is not needed, and the hidden trouble of leakage is greatly reduced; and because the valve cover and the sleeve are made of thin stainless steel sheets, the material cost is reduced, and the volume is small.

The model utility content
The technical problems to be solved in the utility model be overcome exist in the prior art easily cause hidden danger of quality and the high problem of manufacture cost because of the structural design reason causes valve gap and sleeve pipe, a kind of diaphragm electromagnetic valve of novel structure is provided.
For achieving the above object, the utility model is by the following technical solutions:
A kind of diaphragm electromagnetic valve, have by a valve seat and a cavity of valve gap assembling formation, be provided with diaphragm in the middle of the cavity, valve gap, diaphragm and valve base chamber are assembled with screw, valve gap top and sleeve pipe lower end disk weld or are drawn into one, and sleeve pipe top cooperates with end socket and is welded, and is provided with core iron in the sleeve pipe, core iron top endoporus is provided with pressure spring, and the core iron bottom has extension spring to be connected with the pilot valve of diaphragm riveted joint.It is characterized in that: valve gap and sleeve pipe are that metallic material drawing moulding forms, and valve gap and sleeve combination are integral.
As the embodiment of the utility model diaphragm electromagnetic valve, valve gap is that the stainless steel materials drawing forms.
As the embodiment of the utility model diaphragm electromagnetic valve, sleeve pipe be stainless steel materials be drawn into "
" shape, the circular hole external diameter is consistent in the middle of the disk diameter valve gap of lower end.
As the embodiment of the utility model diaphragm electromagnetic valve, circular hole upper end plane butt welding is argon arc welding or plasma welding in the middle of sleeve pipe lower end disk and the bonnet 13.
As the embodiment of the utility model diaphragm electromagnetic valve, valve gap and sleeve pipe can be made of one, and directly draw with stainless steel materials to form.
The utility model is because above structure has been cancelled screw connector and seal ring, valve gap draws with stainless steel materials and forms, integrally welded with sleeve pipe, or valve gap and sleeve pipe directly be drawn into one, so structure is simple relatively, does not need fine finishing, reduce greatly and leak hidden danger, because both are Stainless Sheet Steel, the cost of material is low again, and volume is little.

Specific embodiments
Describe the embodiment of the utility model diaphragm electromagnetic valve below with reference to the accompanying drawings in detail.
Fig. 2 is the utility model diaphragm electromagnetic valve embodiment explanatory drawing, because the diaphragm electromagnetic valve of illustrated embodiment uses in pipeline, therefore, it includes valve seat 10, be provided with snout cavity 10a in the valve seat 10, outlet plenum 10b, primary valve 10c, Vehicle Processing after Vehicle Processing or the stainless steel investment casting after adopting brass to forge, diaphragm 11 is arranged at valve seat 10 tops, diaphragm 11 forms sealing pair with primary valve 10c, there is pad 25 below in the middle of the diaphragm 11, the top has packing ring 24 successively, pilot valve 12, be riveted together with diaphragm 11, there is valve gap 13 diaphragm 11 outer rims top, and valve gap has four holes for 13 4 jiaos, with diaphragm 11, valve seat 10 usefulness screws 26 are fastening, there is sleeve pipe 17 valve gap 13 tops, adopt stainless steels to draw with valve gap 13 and form, and two parts form with argon arc welding or plasma welding, see Fig. 4, perhaps valve gap 13 directly is drawn into one with stainless steel with sleeve pipe 17, see Fig. 5, sleeve pipe 17 top endoporus cooperate with end socket 20 and the argon arc welding welding, and core iron 16 is arranged in the sleeve pipe 17, core iron 16 upper end endoporus are equipped with pressure spring 18, sealing block 15 is equipped with in the lower end, and core iron 16 lower ends are connected with extension spring 14 with pilot valve 12 upper ends simultaneously, the sleeve pipe 17 outer coils 21 that are equipped with.
In the working procedure: when coil 21 energisings, the electromagnetic force that produces moves upward and end socket 20 adhesives core iron 16, pilot valve mouth 12a opens, at this moment diaphragm 11 epicoele media are through pilot valve 12 orifice flow inlet/outlet chamber 10b, pressure reduces, and this moment, the pushed at high pressure diaphragm 11 of snout cavity 10a was opened primary valve 10c, simultaneously because extension spring 14 effects make diaphragm 11 be in the state that upwards draws, valve is opened, and has realized the circulation of medium; When coil 21 outages, magnetic force disappears, and core iron 16 resets under pressure spring 18 effects, closes 12 mouthfuls of pilot valves and primary valve 10c successively, and the pressure of diaphragm 11 epicoeles is by equalizing orifice 11a and snout cavity 10a pressure balance, and valve cuts out, and has realized the disconnection of medium.
Because valve gap 13 adopts argon arc welding or plasma welding with sleeve pipe 17, or directly be drawn into one, avoided because vibration or certain operation feasible being threaded become loosening the cause leakage of valve in long-term work, increase reliability, screw connector 22 and 23 2 parts of seal ring have been reduced simultaneously, structure is simple relatively, low cost of manufacture.
At last, should be pointed out that above embodiment only is the more representational example of the utility model.Obviously, the technical solution of the utility model is not limited to the foregoing description, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
