As shown in fig. 2, 3 and 5, specifically, during the installation and process, the two ends of the wire frame 20 respectively abut against the supporting surface 28 and the lower cover 15, the static valve core 14 is also supported on the lower cover 15, the lower cover 15 is supported on the supporting seat 21, and the supporting seat 21 is supported on the spin riveting surface 30.

In addition, when the spin riveting surface 30 is inwards bent and wrapped, the supporting seat 21 can be compressed in layout, so that the fit between the spin riveting surface 30 and the supporting seat 21 can be prevented from loosening in the long-term use process, and the reliability of the fit between the electromagnetic driving mechanism 2 and the shell mechanism 1 is improved. Meanwhile, the spin riveting surface 30 can support the supporting seat 21 through a spin riveting process, and other accessories are not needed to support the supporting seat 21, so that the rib plate of the electromagnetic diaphragm valve is matched, and meanwhile, the assembly efficiency of the electromagnetic diaphragm valve can be improved due to the simplicity and rapidness of the spin riveting process. In the present embodiment, the middle cover 9 and the upper cover 6 are integrally formed with the wire frame 20 and are disposed directly on the support surface 28, that is, directly on the support surface 28. The diaphragm 10 is supported above the support surface 28, and the support surface 28 is also used as a reference surface. This can greatly reduce the influence of tolerances of intermediate members, and eventually improve the accuracy of the engagement between the electromagnetic drive mechanism 2 and the housing mechanism 1 in the up-down direction.
As shown in fig. 3 and 4, in the present embodiment, the body mechanism has a support pad 11 disposed on the middle cover 9, and the diaphragm 10 is disposed on the support pad 11. Namely: the diaphragm 10 is sandwiched between the middle cap 9 and the support pad 11. In this embodiment, the material of the support pad 11 and the support base 21 is PA66+20gf, wherein the support pad 11 is a ring-shaped geometric body.

In this embodiment, the wall thickness of the housing 18 is 0.6mm. In another embodiment, the wall thickness of the housing 18 may be 0.4-1 mm.
In the present embodiment, as shown in fig. 2 to 4, the diaphragm 10 is provided with a ring of sealing protrusions protruding upwards, and the sealing protrusions are matched with the middle cover 9, so that the middle cover 9 and the diaphragm 10 are sealed in an up-down compression manner, and the tightness between the middle cover 9 and the diaphragm 10 is improved.
In this embodiment, as shown in fig. 5, the tubular section 29 is a cylindrical tubular body. The tubular section 29, the support surface 28 and the rivet surface 30 are integrally formed, and the housing 18 is made of stainless steel. The rivet face 30 is bent and deformed inward by a rivet process.
As shown in fig. 5 and 6, in the present embodiment, the clinching face 30 is provided with a first positioning port 31; the lower cover 15 is provided with a second positioning opening 32 and a first limiting protrusion 33 matched with the first positioning opening 31; the supporting seat 21 is provided with a second limiting protrusion 34 which is matched with the second positioning opening 32. Specifically, the lower cover 15 is clamped at the first positioning opening 31 through the first limiting protrusion 33, so that the lower cover 15 cannot rotate relative to the housing 18; the supporting seat 21 is clamped at the second positioning opening 32 through the second limiting protrusion 34, so that the supporting seat 21 cannot rotate relative to the shell 18 and the lower cover 15.
The electromagnetic diaphragm valve of the embodiment can ensure that in a long-term working process, the electromagnetic driving mechanism 2 and the shell mechanism 1 still have accurate matching precision, and ensure the reliability of switching the first liquid outlet section 23 and the second liquid outlet section 24 by the electromagnetic driving mechanism 2. Meanwhile, the arrangement of the spin riveting surface 30 can improve the assembly efficiency of the electromagnetic diaphragm valve. In addition, in the electromagnetic diaphragm valve of the embodiment, when the shell 18, the middle cover 9 and the upper cover 6 in the shell mechanism 1 are detachably assembled through the connecting screw 7, a liquid containing cavity can be formed between the upper cover 6 and the middle cover 9; simultaneously, the liquid inlet section 22 and the first liquid outlet section 23 of the upper cover 6 and the second liquid outlet section 24 of the middle cover 9 are respectively communicated with the liquid containing cavity. Not only simplifying the connection structure among the shell 18, the middle cover 9 and the upper cover 6, and facilitating the installation; while also greatly simplifying the specific structure of the housing 18, the middle cap 9 and the upper cap 6.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, and various modifications and variations may be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
