Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1-2 is referred to, the utility model provides a kind of technical scheme：A kind of pump discharge high-pressure check valve, including valve body
1, the inner chamber of the valve body 1 is provided with high pressure valve pocket 2, the left and right ends of the high pressure valve pocket 2 respectively with water inlet 3 and delivery port 4
It is connected, valve seat 5 is installed in the access way in the high pressure valve pocket 2, the right-hand end of the valve seat 5 is connected with flap 6,
It is connected on the right side wall of the flap 6 by lock-screw 8 with rocking bar 7, and the other end of rocking bar 7 passes through rocker shaft 14 and valve
Body 1 is flexibly connected, and the top of the high pressure valve pocket 2 is connected with end cover 9, and the left and right sides of upper end cover 9 passes through
Bolt 12 is fixedly connected with the gland 10 positioned at the top of valve body 1, and pendant collet is connected between the upper end cover 9 and gland 10
