Description
Technical field
The utility model is related to valve field, more particularly, to be a kind of check valve.
Background technology
Check-valves is arranged on fluid line, for allowing fluid only to flow in one direction, the check-valves when reverse flow of fluids
It can close automatically.But if closure of check ring obtains too fast, it is possible to create there is the water hammer of destruction to pipeline, present one
As by check-valves be configured with damping structure, to slow down the shut-in time of check-valves.But the sky that existing damping structure takes
Between bigger or connector it is much complicated.
Utility model content
A kind of the purpose of this utility model is to overcome above-mentioned deficiency, there is provided valve simple in construction.
To achieve the above object, technical solution of the present utility model is：A kind of valve, including valve body, set in valve body
There is cavity, cavity is respectively equipped with inlet and outlet at the both ends of valve body, and cavity is provided with flap seat in entrance, is hinged on flap seat
There is flap, the import of cavity can be opened and closed by rotating flap, and the back side of flap is provided with bar hole, and the lateral wall of valve body is provided with oil
Cylinder, the piston rod of oil cylinder are stretched into cavity, and the piston rod of oil cylinder is provided with bearing pin, and pin sleeve is in the bar hole of flap.
Preferably, oil cylinder is inclined on valve body, and the sidepiece of valve body is provided with the side window of UNICOM's cavity, is set on side window
There is cover plate.
Preferably, flap seat is provided with the through hole matched with the import of cavity, and through hole is provided with the taper hole matched with flap.
By using above-mentioned technical scheme, the beneficial effects of the utility model are：The utility model passes through on flap
Bar hole can is set to connect oil cylinder as damping unit, it is simple in construction.Side window is used for the installation and maintenance of flap, can make ratio
The also big flap of valve body import or outlet can load, and flap is installed in the case where oil cylinder is fixed on valve body.Flap
The use of seat can reduce the difficulty of processing in the cavity of valve body, make the sealing of flap more preferable.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is structural representation when the utility model flap is closed.
Main Reference Numerals explanation：
Valve body 1；Cavity 11；Import 12；Outlet 13；Side window 14；Cylinder 2；Piston rod 21；Bearing pin 22；Flap 3；Bar shaped
Hole 31；Flap seat 4；Through hole 41；Cover plate 5.
Embodiment
The utility model is further illustrated below in conjunction with the drawings and specific embodiments.
As Figure 1-Figure 2, the utility model, including a kind of valve, including valve body 1, valve body 1 is interior to be provided with cavity 11, chamber
Body 11 is respectively equipped with import 12 and outlet 13 at the both ends of valve body 1, and cavity 11 is provided with flap seat 4 at import 12, and flap seat 4 can
Processing in addition, precision is higher, and flap 3 is hinged with flap seat 4, and flap seat 4 is logical provided with what is matched with the import 12 of cavity 11
Hole 41, through hole 41 are provided with the taper hole that match with flap 3, and rotation flap 3 can be opened and closed the import 12 of cavity, on the back side of flap 3
Provided with bar hole 31, the lateral wall of valve body 11 is provided with oil cylinder 2, and the piston rod 21 of oil cylinder 2 is stretched into cavity 11, the work of oil cylinder 2
Stopper rod 21 is provided with bearing pin 22, and bearing pin 22 is enclosed in the bar hole 31 of flap 3.When oil cylinder stretches, bearing pin 22 is in bar hole 31
Slide driving flap 3 to rotate, realize opening and closing of the flap 3 to import 12.The structure can reduce linkage between cylinder and flap
Setting, structure is simpler, easy to maintenance.
Oil cylinder 2 is inclined on valve body 1, can reduce overall volume, facilitates push-and-pull action of the oil cylinder to flap, valve body 1
Sidepiece be provided with the side window 14 of UNICOM's cavity 11, side window 14 is provided with cover plate, and flap 3 can load from side window 14.
It is above-described, preferred embodiment only of the present utility model, it is impossible to limit the model of the utility model implementation
Enclose, every equivalent change made according to present utility model application the scope of the claims and decoration, should all still fall within the utility model and cover
In the range of.
