Embodiment

Like Fig. 1,2,3, shown in 4; Province of the present invention water valve can use on the inlet pipeline that is installed on various watering equipments (like tap, the gondola water faucet of sanitaryware); By a valve body 1; Spool 2 and elastic component 3 formed, and this spool 2 is with in elastic component 3 combines to be located at this valve body 1, and this spool 2 can axially move back and forth in valve body 1 under its pressure at two ends difference effect.

Said valve body 1 tool hollow chamber, two ends are for being communicated with the water intake 11 and the water outlet 12 of chamber, and the aperture of this water intake 11 is greater than the aperture of water outlet 12, the water intake 11 corresponding water pipes that are communicated with, 12 corresponding watering equipments that are communicated with of water outlet; These valve body 1 water intake 11 port outer rims are protrusion one flange 13 outwards; Use spacing when being installed on pipeline for valve body 1; And being divided into the upper and

lower chamber

14,15 that communicates in this hollow reservoir, the internal diameter of epicoele 14 is greater than the internal diameter of cavity of resorption 15, and this cavity of resorption 15 is provided with retaining edge 16 with epicoele 14 joining places; This retaining edge 16 is on the axially symmetrical port that is molded over cavity of resorption 15; And the inwall correspondence of cavity of resorption 15 the retaining edge 16 below be absorbed in a groove 17, also can connect to epicoele 14 for ease of making this groove, the retaining edge 16 then be molded between the groove in upper and lower chamber; In addition another mode of execution of the present invention be this retaining edge 16 can be one the protrusion the port that is located on cavity of resorption 15 on collar flange (seeing shown in Figure 7).
