Specific implementation mode
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, it should be understood that preferred reality described herein
Apply example only for the purpose of illustrating and explaining the present invention and is not intended to limit the present invention.
Embodiment：As shown in Figs. 1-2, including valve body 3,3 one end of the valve body are provided with water inlet 1, and the other end is provided with
Water outlet 2,1 side of the water inlet are provided with flashboard seat 4, and 4 side of flashboard seat is provided with valve plug A7, the valve plug A7 mono-
Side is provided with the first sliding groove 10, and pipelined channel 8 is provided between the first sliding groove 10 and valve body 3, is provided on the valve plug A7
First fixed pin 5, is provided with the second fixed pin 6 in the first sliding groove 10, first fixed pin, 5 and second fixed pin 6 it
Between be connected with the one end spring A9, the valve plug A7 and be provided with connecting rod 11,11 other end of the connecting rod passes through the first sliding groove 10
It is fixed with valve plug B13, the sides the valve plug B13 are provided with second sliding slot 12, and third fixed pin is provided on the valve plug B13
14, the 4th fixed pin 15 is provided in the second sliding slot 12, is connected between 14 and the 4th fixed pin 15 of the third fixed pin
There is spring B 16.
In order to keep this kind of high-voltage one-way valve easy to use, 3 top of the valve body is slightly wide, relatively narrow by tail portion, the valve
Fill in A7 in the first sliding groove 10, the valve plug B13 in second sliding slot 12, be arranged on the flashboard seat 4 it is fluted, it is described
Valve plug A9 is in pointed design, and wedge angle is inserted into groove and agrees with, and the valve plug B13 is located at the narrow place in 3 tail portion of valve body, and and valve body
3 inner walls are bonded, and second fixed pin 6, the third fixed pin 14 are in hollow cylinder, and size is respectively than the first fixed pin
5,15 size of the 4th fixed pin is big.
Structure of the invention reasonable design, at work, high pressure water flow push valve plug A7 into the first sliding groove 10, valve plug A7
Wedge angle detached with the groove of flashboard seat 4, while valve plug B13 is pushed into second sliding slot 12, the inner wall of valve plug B13 and valve body 3
It is no longer bonded, flow is discharged by pipelined channel 8 from water outlet 2.When being no longer passed through high pressure water flow, valve plug A7 is spring A9's
It is popped up under effect, the groove of the wedge angle for making valve plug A7 and flashboard seat 4 agrees with again, shuts the entrance of pipelined channel 8, prevents
Flow passes through the ball-and-seat.At the same time valve plug B13 is made valve plug B13 again by the elastic force of the pulling force and spring B 16 of valve plug A7
