Above-mentioned valve body is connected through screw with valve gap.
Be respectively arranged with filter screen on the inner chamber boss of the water-in and water-out joint of above-mentioned valve body.
The lower surface of above-mentioned spool is provided with the projection of three location seal rings, and middle projection is provided with barb, and described through hole is arranged on the center line that stretches into another projection in the water output connector inner chamber.
Above-mentioned through hole is provided with the conducting bar of internal diameter less than the through hole internal diameter, can prevent that sealing is back to water intake.
Above-mentioned seal ring is provided with the relatively thinner U type or the axial stretching portion of S type.
Above-mentioned spool is provided with the spring that makes spool in the closed position in the movable chamber.
The utility model is compared existing technology and is had following outstanding and beneficial technical effects:
1, the utility model product can be put arbitrarily according to the water pipe needs under the correct situation of assurance water-in and water-out installation direction, does not receive the restriction of mounting point;
2, the utility model product adds filter screen respectively between entery and delivery port and water pipe, can play the effect of impurity in the filtered water, thereby makes one-way valve that higher sensitivity arranged;
3, valve body of the utility model and valve gap are independent separate structure, the retaining screw of valve body and valve cover chamber under maintenance needs only and dismantles like need, the convenient cleaning or the replacing spool;
4, simple in structure, the good seal performance of the utility model, long service life are fit to be installed in various occasions such as indoor, outdoor.

Embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to accompanying drawing 1-6:
A kind of novel one-way valve; Comprise valve body 2, valve gap 6 and sealed valve core 4; One end of valve body 2 is provided with that water supply connector 1, the other end are provided with water output connector 3, the middle part is provided with the valve pocket 22 with valve gap 6 sealings, and water supply connector 1 extends in the valve pocket 22 and forms valve seat 23 to a side bending of valve gap 6, and valve seat 23 is provided with spool 4; On spool 4 bottom surfaces of valve seat 23 and external cylindrical surface, be set with telescopic seal ring 8; The inwall fitted seal of the outer side wall of seal ring 8 and valve pocket 22 is provided with spool 4 movable chambeies 21 between spool 4 and the valve gap 6, be provided with the through hole 42 that connects spool 4 and seal ring 8 between water output connector 3 inner chambers and the movable chamber 21.
Above-mentioned valve body 2 is connected through screw 9 with valve gap 6.
Be respectively arranged with filter screen 10 on the inner chamber boss of the water-in and water-out joint (1,3) of above-mentioned valve body 2.
