Mechanism includes valve element, valve rod and installing plate, and valve element upper end coordinates with water inlet closure, and valve element lower end is mutually socketed with valve rod upper end
And the first spring is set therebetween, installing plate is fixed in valve pocket, and installing plate is provided with opening, and stem outer circumference is arranged
There is second spring, valve rod upper end is provided with the first nut with the spacing cooperation of second spring, and valve rod lower end is through installing plate and is provided with
With the second nut of the spacing cooperation of installing plate.
Further, valve body is covered by upper valve body and lower valve body and formed, and upper valve body passes through locked clip device with lower valve body.
Further, the sealing ring coordinated with valve interior wall sealing is embedded with the closure face of valve element.
Further, valve element is provided with the lead being bonded with water inlet perisporium.
The utility model has the beneficial effect that：The utility model sets the second spiral shell with the spacing cooperation of installing plate in valve rod lower end
Mother, it is capable of the socket distance of regulating valve stem and valve element, and ensures that valve element blocks with water inlet under the elastic reaction of the first spring
Coordinate, second spring is arranged in the periphery of valve rod and the first nut is set in valve rod upper end, in the elastic reaction of second spring
Under be able to ensure that the socket distance of valve rod and valve element, effectively prevent spring decline caused by valve leak in addition can not open
Closing is opened, extends the service life of check-valves.The utility model structure setting is reasonable, can prevent spring from declining to be made
Into valve leak even can not open and close, extend the service life of check-valves.

Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of check-valves described in the utility model, including valve body 1, valve body 1 are interior formed with valve pocket 2, valve
Body 1 is provided with the water inlet 3 connected with valve pocket 2, the opening 6 of the opening of discharge outlet 4, first 5 and second, and the first opening 5 and second is opened
Mouth 6 passes through for medium, and be provided with valve pocket 2 includes valve element 7, valve rod 8 and pacify with 3 corresponding controlling organization of water inlet, controlling organization
Loading board 9, the upper end of valve element 7 coordinate with the closure of water inlet 3, and the lower end of valve element 7 is mutually socketed with the upper end of valve rod 8 and set therebetween
First spring 10, installing plate 9 are fixed in valve pocket 2, and installing plate 9 is provided with opening 19, and the periphery of valve rod 8 is arranged with the second bullet
Spring 11, the upper end of valve rod 8 are provided with the first nut 12 with 11 spacing cooperation of second spring, and the lower end of valve rod 8 is through installing plate 9 and is provided with
With the second nut 13 of 9 spacing cooperation of installing plate；The second nut 13 is set to be capable of the socket distance of regulating valve stem 8 and valve element 7, and
Ensure that valve element 7 coordinates with the closure of water inlet 3 under the elastic reaction of the first spring 10；The nut of second spring 11 and first is set
12, the socket distance of valve rod 8 and valve element 7 is able to ensure that under the elastic reaction of second spring 11, is effectively prevented under spring
Valve leak caused by drop even can not open and close, extend the service life of check-valves.
Valve body 1 is covered and formed by upper valve body 14 and lower valve body 15, and upper valve body 14 is locked with lower valve body 15 by clip 16；Valve
The sealing ring 17 coordinated with the inner wall sealing of valve body 1 is embedded with the closure face of core 7, sealing effectiveness is preferable；Valve element 7 is provided with entering
The lead 18 of the perisporium fitting of the mouth of a river 3, can prevent valve element 7 from being offset when moving reciprocatingly.
Operation principle of the present utility model is intake from water inlet 3, and valve element 7 is moved down by the pressure of medium, first
Spring 10 is compressed, and medium is flowed through by opening 19, is discharged from discharge outlet 4, and when inflow is smaller, the first spring 10 is multiple
Position, valve element 7 coordinate with the closure of water inlet 3；After water check valve usage time is longer, during the flexibility decrease of second spring 11, valve rod 8
Because self gravitation can move down, valve element 7 is caused to move down so that valve element 7 departs from spacing cooperation, it is necessary to adjust first with water inlet 3
Nut 12, valve element 7 can be supported by ensureing the elastic force of second spring 11；When the flexibility decrease of the first spring 10, valve element 7 will decline
And depart from spacing cooperation, it is necessary to adjust the second nut 13 with water inlet 3, valve rod 8 is moved up, and the first nut 12 is adjusted, make valve
Bar 8 can keep stable.
Described above is only better embodiment of the present utility model, therefore all according to described in the utility model patent application range
