Specific embodiment
Now in conjunction with the drawings and specific embodiments, the present invention will be further described.
With reference to Fig. 1, Fig. 2, Fig. 3, revealed the utility model embodiment is a kind of check-valves, including upper valve body 1, lower valve
Body 2, valve seat 3, flap 4, valve shaft 5, the upper valve body 1 are connect with lower valve body 2 by bolt 11, the upper valve body 1 and lower valve body 2
Between be provided with the second sealing ring 12 for sealing upper valve body 1 Yu lower valve body 2, second sealing ring 12 is around being set to institute
The joint of upper valve body 1 Yu lower valve body 2 is stated, the upper valve body 1 offers inner cavity with lower valve body 2, and the upper valve body 1 offers out
The mouth of a river, the lower valve body 2 offer water inlet, and the flap 4 can close water inlet and be set to the water inlet, the flap
The retention bead 21 for preventing the flap 4 from skidding off the inner cavity, the retention bead 21 are provided between 4 and lower valve body 2
It is fixedly installed on 2 inner wall of lower valve body, 21 upper surface of retention bead and 4 lower end surface of flap are inconsistent, the valve
The first sealing ring 41 is provided between valve 4 and lower valve body 2, first sealing ring 41 surround and is set to 4 lower end surface of flap,
5 lower end of valve shaft is fixedly installed on 4 upper surface of flap, and 3 center of valve seat offers the limit passed through for the valve shaft 5
Position hole 31,5 upper end of valve shaft are arranged in the limit hole 31, and the valve seat 3 is located at 31 side of limit hole and offers
For the water-flowing trough 32 that fluid passes through, being provided between the valve seat 3 and flap 4 makes the sealing of flap 4 contact at the water inlet
The spring 42 of mouth, the spring 42 are sheathed on the valve shaft 5, and 42 upper end of spring and valve seat 3 are inconsistent, 5 edge of valve shaft
Radially fixed to be provided with supporting table 51,42 lower end of spring and the supporting table 51 are inconsistent, described interior intracavitary to be provided with use
