Fig. 1 be this utility model cleaning machine low voltage starter static time one preferred embodiment structural representation；
The structural representation of one preferred embodiment when Fig. 2 is the work of this utility model cleaning machine low voltage starter.
Detailed description of the invention
Technical scheme in this utility model embodiment will be clearly and completely described below, it is clear that described embodiment is only a part of embodiment of the present utility model rather than whole embodiments.Based on the embodiment in this utility model, all other embodiments that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Referring to Fig. 1 and Fig. 2, this utility model embodiment includes:
A kind of cleaning machine low voltage starter, including: water-outlet body 10, it is provided with valve pocket 6 in the intake tunnel of described water-outlet body 10, it is equipped with valve rod 3 in described valve pocket 6, described valve rod closure support end is provided with ball sealer 8, and ball sealer 8 is connected with valve rod 3 by ejector pin 11, and valve rod 3 other end is pressure adjustable side.
Preferably ball sealer 8 is plugging steel ball.
Being equipped with pressure spring 4 on the valve rod 3 of described pressure adjustable side, the pressure of pressure spring 4 is regulated by look nut 5.Described pressure spring 4 and look nut 5 are assemblied on the valve rod 3 extended to outside water-outlet body 10.
Described ejector pin 11 shank is provided with guide part, guide part is provided with annular protrusion, valve rod 3 main body is provided with the ejector pin installing hole of accommodating ejector pin 11, and described ejector pin installing hole includes that the first pilot hole and the second pilot hole, the first pilot hole and the second pilot hole are the different stepped holes of diameter.The diameter of the first pilot hole is less than the diameter of the second pilot hole.
