Specific embodiment
The following examples illustrate the utility model, but is not intended to limit the scope of the present invention.
A kind of novel slow-closing check-valves provided by the embodiment of the utility model, refering to Figure 1, include valve body 1, it is described
Enter aquaporin port inner ring equipped with valve seat 3 inside valve body 1, it is described enter aquaporin be tubular structure, it is described enter aquaporin inside
Position close to the valve seat 3 is connected with fixed frame 2；Described 2 one end of fixed frame is connected with shaft 4；It is arranged in the shaft 4
Flap sealing plate 5；5 outer ring of flap sealing plate is equipped with screw wing 6；The flap sealing plate 5 is set close to 3 side of valve seat
There is rubber ring 7；The rubber ring 7 is trapezoidal.
In use, blow-off valve flap seal plate is flowed out to the other end after fluid enters valve body, when fluid reflux, will push
Flap sealing plate will finally enter aquaporin closure of openings to valve body movement, prevent water adverse current；Due to the presence by screw wing 6, make
Flap sealing plate is rotating to valve seat movement, reduces its directly mobile impact force, simultaneous rubber ring can either be in valve
Flap seal plate and valve seat play buffer function when meeting, with can play sealing function.
In order to improve stablizing effect, please refer to shown in Fig. 2, the fixed frame 2 include with it is described enter aquaporin inner wall fix
The annulus pedestal 21 of connection and the support base 22 connected by several connecting rods 23；The support base 22 is in the valve seat 3
At the heart and the annulus pedestal 21, support base 22 and valve seat 3 are on same axial line；The support base 22 is far from the annulus
The side of pedestal 21 is vertical with the shaft 4 to be connect, the shaft 4 with it is described enter aquaporin it is parallel；The shaft 4 is far from branch
Support 22 one end of seat is connected with block；Not only fluid smooth flow had been achieved the purpose that, but also can play a part of stablizing support.
It should be noted that the flap sealing plate 5 is close to the support base in order to reach better counterflow-preventing effect
The disk-shaped structure of 22 side indent and the evagination far from the support base 22；5 diameter of flap sealing plate is greater than and institute
State 3 internal diameter of valve seat.
In order to reach preferably buffering and counterflow-preventing effect, the rubber ring 7 is close to the 5 indent side of flap sealing plate
Edge and close to 22 side of support base diameter be less than 3 internal diameter of valve seat, the rubber ring 7 is far from the support
The diameter of 22 sides of seat is greater than the internal diameter of the valve seat 3.
In use, when flap sealing plate is mobile to valve seat, rubber loop diameter be less than the side of valve seat first with enter valve seat,
Since rubber ring outer ring is inclined so when rubber ring outer ring and valve seat inner ring meet, indent can occur for rubber ring outer peripheral surface
Phenomenon, at the same structure also can deformation occurs, both changes can all reduce flap sealing plate and bring the impact force of valve seat, to mention
The service life of high slow-closure type valve.
In order to reach better buffering effect, please refer to shown in Fig. 3 and Fig. 4, elongatedness direction is set on 4 axial plane of shaft
There is spiral chute 41；5 inner ring of flap sealing plate is fixedly connected with the sliding block 51 with 41 shiding matching of spiral chute.
Although above having made detailed description to the utility model with generality explanation and specific embodiment,
On the basis of the utility model, it can be made some modifications or improvements, this is apparent to those skilled in the art
's.Therefore, these modifications or improvements on the basis of without departing from the spirit of the present invention, belong to the utility model and want
Seek the range of protection.
