Description
Technical field
The present invention relates to check-valves, in particular to a kind of differential Slow Close Valve of angie type belongs to check-valves technical field.
Background technique
The reliability and leakproofness that traditional check-valves flap is contacted with valve base sealing pair cannot be reinforced, it is difficult to reduce valve
The service life of impact force between valve and valve base sealing pair, valve is short.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the defects of the prior art, provide a kind of differential Slow Close non-return of angie type
Valve.
In order to solve the above-mentioned technical problems, the present invention provides the following technical solutions:
A kind of differential Slow Close Valve of angie type of the present invention, including valve body, flap, cavity, guide rod, piston and valve deck, it is described
Valve body inner top is equipped with cavity, and the cavity inner top is equipped with flap, connects guide rod, the guiding below the flap
Bar end is equipped with piston, and the flap is connect by guide rod with piston, and the valve body end is equipped with valve deck.
Preferably, the piston end is equipped with sealing ring made of rubber material.
Preferably, the outer diameter of the piston is identical as the internal diameter at the top of valve deck.
Preferably, the body top is equipped with capping, and fixed by two groups of bolts.
Preferably, digging on the guide rod and the cavity of cavity junction has sliding groove, the guide rod and cavity
It is slidably connected.
The beneficial effects obtained by the present invention are as follows being: the present invention realizes closing and breakdown action under pressure medium effect,
In opening process, pressure medium is acted below flap, and flap is pushed to open, and in flap opening process, pressure medium can be through chamber
After body lower part many places deflector hole enters below piston, piston is continued to press on, facilitates flap and quickly opens.In the initial rank of closing
Section, under the action of pressure medium, piston by guide rod drive flap quickly move down, when outside piston garden with cavity internal diameter
When generating the cooperation stage, damping effect can be generated, flap can slow down movement at this time, reach Slow Close purpose, until the same valve seat of flap
Contact closes medium, plays the role of non-return, and the reliability and leakproofness that flap is contacted with valve base sealing pair are strengthened, reduction
The service life of valve can be improved in impact force between flap and valve base sealing pair.
Detailed description of the invention
Fig. 1 is open state schematic diagram of the invention；
Fig. 2 is closed mode schematic diagram of the invention.
Specific embodiment
With reference to the accompanying drawings and examples, further description of the specific embodiments of the present invention.Following embodiment is only
For clearly illustrating technical solution of the present invention, and not intended to limit the protection scope of the present invention.
As shown in Figs. 1-2, the present invention provides a kind of differential Slow Close Valve of angie type, including valve body 1, flap 2, cavity 3, leads
To bar 4, piston 5 and valve deck 6,1 inner top of valve body is equipped with cavity 3, and 3 inner top of cavity is equipped with flap 2, institute
Connection guide rod 4 below flap 2 is stated, 4 end of guide rod is equipped with piston 5, and the flap 2 is connected by guide rod 4 and piston 5
It connects, 1 end of valve body is equipped with valve deck 6.
Further, 5 end of piston is equipped with sealing ring made of rubber material, guarantees good air-tightness.
Further, the outer diameter of the piston 5 is identical as the internal diameter at 6 top of valve deck, facilitates the folding at 6 top of valve deck.
Further, it is equipped with capping at the top of the valve body 1, and is fixed by two groups of bolts, makes more compact structure.
Further, digging on the cavity 3 of 3 junction of the guide rod 4 and cavity has sliding groove, 4 He of guide rod
Cavity 3 is slidably connected, and guide rod 4 is facilitated to move up and down with piston 5.
Specifically, guide rod 4 of the present invention connects building block with flap 2, piston 5, which can pump,
Pressure medium effect is lower to realize closing and breakdown action, and in opening process, pressure medium acts on 2 lower section of flap, pushes valve
Valve 2 is opened, and in 2 opening process of flap, pressure medium can continue to push away after 3 lower part many places deflector hole of cavity enters 5 lower section of piston
Piston 5 facilitates flap 2 and quickly opens.In the initial stage of closing, under the action of pressure medium, piston 5 passes through guiding
Bar 4 drives flap 2 quickly to move down, and when the outer garden of piston 5 generates the cooperation stage with 3 internal diameter of cavity, can generate damping effect,
Flap 2 can slow down movement at this time, reach Slow Close purpose, until flap 2 is contacted with valve seat, close medium, play the role of non-return, this
The design advantage of structure is, the reliability and leakproofness that flap 2 is contacted with valve base sealing pair are strengthened, reduce flap 2 with
The service life of valve can be improved in impact force between valve base sealing pair.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvements and modifications can also be made, these improvements and modifications
Also it should be regarded as protection scope of the present invention.
