(1) technical problem that will solve
The purpose of this utility model will overcome above-mentioned shortcoming exactly, aims to provide a kind of leading type plastic electromagnetic valve.
(2) technological scheme
For achieving the above object, leading type plastic electromagnetic valve of the present utility model, comprise valve body, valve gap and electromagnetic mechanism, described valve body comprises import and outlet, described outlet upper end is provided with primary valve, forms a chamber between described primary valve and valve gap, is provided with diaphragm group in this chamber, between described diaphragm group and chamber, be provided with diaphragm spring, described diaphragm group one side is provided with pilot hole; Described electromagnetic mechanism comprises movable spool, iron core spring, every group and electromagnetic coil, described movable spool is positioned at the central authorities of electromagnetic coil, by described iron core spring, be connected every group elasticity with described, describedly every group, be connected with valve gap employing fine thread, described valve body and valve gap material are modified nylon plastic, and described valve body is provided with copper threaded insert.
Further, between described valve gap and valve body, be provided with pilot port.
Further, described valve body and valve gap are fixed by socket cap screw.
Further, described socket cap screw and copper threaded insert are fixed.
Further, described copper threaded insert directly embeds in injection process.
(3) beneficial effect
Compared with prior art, the technical solution of the utility model has the following advantages: leading type plastic electromagnetic valve of the present utility model, the means of fixation of valve body, valve gap adopts the mode that is directly bumped into copper threaded insert in injection course of working, when greatly having simplified mounting process, also strengthened to greatest extent the intensity being threaded, thereby improved the voltage endurance capability of solenoid valve, can be under the medium of certain pressure switch normal, there is no external leakage phenomenon and produce.
Accompanying drawing explanation
Fig. 1 is leading type plastic electromagnetic valve closed condition structural representation of the present utility model;
Fig. 2 is the unlatching situation structural representation of the utility model leading type plastic electromagnetic valve;
Fig. 3 is the A portion enlarged view of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1 to Figure 3, leading type plastic electromagnetic valve of the present utility model, comprise valve body 1, valve gap 2 and electromagnetic mechanism, described valve body 1 comprises import 11 and outlet 12, described outlet 12 upper ends are provided with primary valve 13, form a chamber 21 between described primary valve 13 and valve gap 2, in this chamber 21, are provided with diaphragm group 3, between described diaphragm group 3 and chamber 21, be provided with diaphragm spring 4, described diaphragm group 3 one sides are provided with pilot hole 31; Described electromagnetic mechanism comprises movable spool 4, iron core spring 5, every group 6 and electromagnetic coil 7, described movable spool 4 is positioned at the central authorities of electromagnetic coil 7, by described iron core spring 5, be connected every group 6 elasticity with described, describedly every group 6, be connected with valve gap 2 employing fine threads 8, described valve body 1 and valve gap 2 materials are modified nylon plastic, and described valve body 1 is provided with copper threaded insert 9.
Between described valve gap 2 and valve body 1, be provided with pilot port 32, when solenoid valve conduction, liquid flows into by pilot port 32, thereby reduces chamber 21 internal pressures, makes to move in diaphragm group 3.
Described valve body 1 is fixing by socket cap screw 91 and copper threaded insert 9 with valve gap 2, and this copper threaded insert 9 directly embeds in injection process, has guaranteed the sealing of whole solenoid valve.
During electromagnetic coil 7 energising, movable core overcomes iron core spring 5 to top offset, and the pressure of diaphragm group 3 epicoeles reduces, and overcomes diaphragm spring 4, and diaphragm group 3 is to top offset, thereby makes fluid can pass through smoothly solenoid valve.During electromagnetic coil 7 power-off, movable core is under the effect of iron core spring 5, and to bottom offset, the pressure of diaphragm group 3 epicoeles increases, and diaphragm group 3 is to bottom offset, thereby block fluid is passed through solenoid valve.
Leading type plastic electromagnetic valve of the present utility model, the means of fixation of valve body, valve gap adopts the mode that is directly bumped into copper threaded insert in injection course of working, when greatly having simplified mounting process, also strengthened to greatest extent the intensity being threaded, thereby improved the voltage endurance capability of solenoid valve, can be under the medium of certain pressure switch normal, there is no external leakage phenomenon and produce.
In sum, above-mentioned mode of execution is not restricted mode of execution of the present utility model, and the modification that all those skilled in the art carry out on the basis of flesh and blood of the present utility model or equivalent deformation, all at technology category of the present utility model.
