Specific embodiment

Below in conjunction with the attached drawing of the utility model, the technical scheme in the embodiment of the utility model is carried out clear, complete Site preparation description, it is clear that the described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments. Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts Every other embodiment, fall within the protection scope of the utility model.

As shown in figs. 1-7, the integral check valve of the present embodiment, the integral check valve include valve body 1,3 and of ball sealer Valve deck 2.

Referring to Fig. 9-12, the shape of valve body 1 is in cylindrical shape, and one end of valve body 1 is machined with fixing groove 12, fixing groove 12 Bottom processing fluted 11, the bottom of groove 11 is machined with the first cone tank 13, and the other end of valve body 1 is machined with one first Through-hole 14 and two the second through-holes 15, one end of two the second through-holes 15 extend to the bottom of fixing groove 12,14 He of first through hole Second through-hole 15 is connect with the first cone tank 13, and two the second through-holes 15 are located at the two sides of first through hole 14, and first is logical The center line of the center line in hole 14 and two the second through-holes 15 is parallel to each other and the center line of first through hole 14 and two second The center line of through-hole 15 in the same plane, connect with first through hole 14 respectively, 14 He of first through hole by two the second through-holes 15 Second through-hole 15 forms outlet.The shape of 3-17 referring to Fig.1, valve deck 2 are in cylindrical shape, and one end of valve deck 2 is machined with import 21, the other end is machined with the second cone tank 22, and import 21 is connect with the second cone tank 22.Referring to Fig. 8, valve deck 2 is loaded on valve body 1 Fixing groove 12, valve deck 2 and the interference fit of valve body 1 are to make valve deck 2 be fixed on fixing groove 12, the first cone tank 13,11 and of groove Second cone tank 22 forms the chamber 4 for accommodating ball sealer 3.Ball sealer 3 loaded in chamber 4, ball sealer 3 respectively with import 21 It is corresponded to each other with outlet, when integral check valve is in sealing state, ball sealer 3 is bonded with valve deck 2, and the sealing of ball sealer 3 is lived in Mouth 21.
