Embodiment
Please refer to Fig. 1 to Figure 12, a kind of water-saving check valve, it comprises a valve body 100, a spool 200, a spring 300 and a valve seat 400.
Described valve body 100 is established in it and is run through the water route 110 of pushing up the end, the fitting recess 120 of peripheral hardware annular, described fitting recess 120 places cover seal ring 130.Described water route 110 inner hole surface comprise the seal section 111 arranged according to water route 110 current forwards, water saving section 112 and affixed section 114 at least.Among the present embodiment, described seal section 111 is set as conical surface section, and described conical surface section constantly becomes big according to the current positive flow to internal diameter, but not as limit, as required, described seal section 111 also can be set as shoulder hole (abut against the ladder surface of shoulder hole by seal ring, realize sealing).Described water saving section 112 inner hole surface are established the raised items 113 of a plurality of annular displays, and among the present embodiment, the slightly larger in diameter that described raised item 113 terminal surfaces surround is in the maximum diameter of conical surface section, but do not exceed according to this, also can equal the maximum diameter of conical surface section.Described affixed section 114 inner hole surface established screw thread.
Described valve seat 400, it comprises that a body 410, is positioned at the center base 420 of body 410 and the spoke 430 of some affixed bodies 410 and center base 420.Described body 410 peripheral hardware buckles, affixed section 114 of the affixed valve body 100 of described body 410 buckles is with affixed valve seat 400 and valve body 100.
Described spool 200, it is slidingly installed with in water route 110.Described spool 200 outer turning surface are arranged with a circular groove 240, and circular groove 240 has ring surface 241 on, once a ring surface 242 and a cylndrical surface 243, and last ring surface 241 external diameters are less than ring surface 242 external diameters down.The seal ring 210 that the sheathed flexible material of described spool 200 outer turning surface is made, and, described normality seal ring 210 outer periphery diameters are greater than last ring surface 241 external diameters, so that seal ring 210 has at least part directly acted on by forward current water pressure, described normality seal ring 210 outer periphery diameters are less than following ring surface 242 external diameters, so that seal ring 210 supports are located at down on the ring surface 242, be out of shape to increase.Among the present embodiment: the maximum outside diameter that is positioned at the part on the seal ring 210 of described spool 200 is less than normality seal ring 210 outer periphery diameters; Normality seal ring 210 outer periphery diameters constitute diameter less than a plurality of protruding platform 113 terminal surfaces; Normality seal ring 210 outer periphery diameters are between the maximum diameter and minimum diameter of seal section 111.
Described spring 300, its contact make spool 200 be subjected to the direction water saving section 112 of serving as reasons and point to the elastic force of seal sections 111 between center base 420 and spool 200.
In order to guarantee spool 200 glide directions, best, to establish in the described center base 420 and run through sliding eye 421, spool is convexly equipped with guide rod 220 200 times, guide rod 220 adaptive insertion sliding eyes 421.
For retaining spring 300, best, described center base 420 end faces are arranged with down circular groove 422, and described spool 200 bottom surfaces are arranged with circular groove 230, and spring 300 socket guide rods 220 and upper and lower end are adaptive respectively to be located in circular groove 230 and the following circular groove 422.
If water route 110 current forward flow and water pressure be greater than elastic force, then spool 200 downstream the pressure direction activity make seal ring 210 be positioned at water saving section 112; Because last ring surface 241 external diameters are less than seal ring 210 external diameters, make seal ring 210 can be subjected to effect of water pressure, under ring surface 242 supports cooperate down, seal ring 210 radially extends out distortion, and fill in interval between adjacent two raised items 113, to reduce the section area between seal ring 210 outer periphery and water saving section 112 inner hole surface; Wherein: pressure is big more, is out of shape greatly more, extends out greatly more, and section area is more little;
Otherwise seal ring 210 is positioned at seal section 111, and seal ring 210 sealing seal sections 111 inner hole surface, is in non-return state.
Among another preferred embodiment, it and a last preferred embodiment difference are: please refer to Figure 13, middle part, described spool 200 upper-end surfaces is convexly equipped with a projection 250, turning surface annular display is convexly equipped with card protruding 260 outside described projection 250 tops, described upper-end surface also is formed with the following ring surface 251 around projection 250, described down ring surface 251 and block the circular groove 240 that forms fitting tight circle 210 between protruding 260.Wherein: since adjacent two cards protruding 260 gapped, therefore be subjected to hydraulic action power area bigger, be out of shape more obvious, better effects if.
The above, only for preferred embodiment of the present invention, so can not limit scope of the invention process according to this, i.e. the equivalence of doing according to claim of the present invention and description changes and modification, all should still belong in the scope that the present invention contains.
