Description
Technical field
Valve technology field is the utility model is related to, more particularly, to a kind of integral type flap damping check valve.
Background technology
Damping check valve is widely used on the pipeline of the industries such as metallurgy, chemical industry, power industry, urban water supply and sewerage, is played anti-
The only effect of medium counter flow, it is one of most widely used valve in various fluid conveying engineerings.Existing damping check valve valve
Valve requirement on machining accuracy is high, and parts are more, complicated, can be in any more production cost.
Utility model content
The utility model is to overcome above-mentioned at least one defect of the prior art, there is provided a kind of integral type flap, which is eliminated the noise, to be stopped
Return valve.The utility model is simple in construction, easy to use, and sealing effectiveness is preferable, and production cost is low.
In order to solve the above technical problems, the technical solution adopted in the utility model is：A kind of integral type flap noise elimination non-return
Valve, including valve body, bonnet and valve element, the valve inner are provided with valve pocket, and the valve element is in the valve pocket, the valve body top
Portion is provided with the open top with valve pocket insertion, and the bonnet is covered in the open top, wherein, the valve element includes
Flap and the spring being set on the flap, the bonnet are provided with through hole, and the top of the flap is worn in the through hole,
The bottom of the flap is provided with pressing plate, and caulking gum is coated with the pressing plate, and so, the flap and caulking gum are just formed
Integral piece, it is simple in construction, it is easy to process；And in traditional check-valves, flap and rubber sheet gasket are two separated parts, are added
Man-hour will also process the position of installation rubber sheet gasket on flap, and then rubber sheet gasket is arranged on flap again, complicated,
Processing industry is inconvenient.The caulking gum of the pressing plate bottom surface is provided with annular flange, and the spring one end withstands the bonnet, separately
The pressing plate is withstood in one end, and the annular flange is flexible, and in the presence of spring force, annular flange is compressed so that
The sealing property of pressing plate is more excellent, can effective prevent leakage.
Further, the inwall of the body top opening is provided with internal thread, and the peripheral outer wall of the bonnet is provided with
With the external screw thread of the screw-internal thread fit, the bonnet is connected with the valve body by screw thread rotation, when valve element breaks down,
Bonnet is easy to open to be repaired.
Further, the through hole on the bonnet is provided with close to the side of the valve pocket facilitates the flap to penetrate described lead to
The problem of guide rib in hole, can effectively preventing flap from deviating from from the through hole of bonnet, and causing check-valves work failure.
Compared with prior art, its advantage is the utility model：
The utility model is that traditional flap and rubber sheet gasket are designed into a part, i.e., the cladding sealing rubber on flap
Glue, flap integral type reduce part, and requirement on machining accuracy is low, and assembling is simple；And the utility model is also on caulking gum
There is provided annular flange, it is this it is simple in construction, sealing property is more preferable, can improve the quality of product, reduce production cost.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
Fig. 2 is the structural representation of the utility model flap.
Embodiment
Accompanying drawing being given for example only property explanation, it is impossible to be interpreted as the limitation to this patent；It is attached in order to more preferably illustrate the present embodiment
