Abstract
The utility model discloses a muting check valve. The muting check valve comprises valve bodies, water inlets and water outlets. Each water inlet and each water outlet are formed in the two ends of each valve body, guide groove assemblies are arranged on the water inlets and extend to a hollow cavity in the valve bodies, limiting assemblies are arranged at the ends of the guide groove assemblies, a movable ball plug is arranged in the guide groove assemblies, and arc grooves matched with the ball plug are arranged at the positions where the ball plug makes contact with the water inlets. The muting check valve has the advantages of being simple in structure and long in service life, achieving muting and the like.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of DRV door.
Background technique
DRV refers to and relies on medium itself to flow and automatic open and close flap, is used for preventing the valve that medium flows backwards, and claims again check valve, one-way valve, reflux valve and back pressure valve.Safety check belongs to a kind of automatic valve, and its Main Function is to prevent that medium from flowing backwards, preventing pump and drive motor reversion, and the releasing of vessel media.Safety check also can be used for may rising to the auxiliary system of pressing over system to pressure wherein to be provided on the pipeline of supply.But the problem that the common existence of current safety check is certain, when water pump is out of service, the refluence of water easily causes the flap in valve to close the sound of generation, affects the working life of valve and easily produces noise pollution.
The model utility content
The technical problem existed for prior art, the utility model provides a kind of DRV door simple in structure.
In order to solve existing technical problem, the technical solution adopted in the utility model is:
A kind of DRV door, the water intake and the water outlet that comprise valve body and valve body two ends, described water inlet is provided with the guide groove assembly, hollow cavity and end that described guide groove assembly extends to valve body inside are provided with limit assembly, described guide groove component internal is provided with movable ball plug, and described ball plug is provided with the water intake contacting point curve bath matched with the ball plug.
Further improvement as check valve of the present utility model:
Be provided with sealing gasket on described curve bath.
Described guide groove assembly comprises that two symmetrically arranged arcs are rectangular.
Described limit assembly is the block that is arranged on guide groove assembly end.
Described valve body and guide groove assembly are one-body molded.
Compared with prior art, the beneficial effects of the utility model are:
Safety check of the present utility model has been made improvement on existing valve, be provided with guide groove assembly and ball plug in the cavity of valve body, and ball plug and water intake are also the arc close contacts, separately on curve bath, be provided with sealing gasket, can effectively prevent the reverse flow of current, when the ball plug contacts with water intake, area is less, when flow reversal is flowed, the sound produced is less, can effective noise reduction function.
The accompanying drawing explanation
Fig. 1 is sectional drawing of the present utility model.
Fig. 2 is the A-A sectional drawing of Fig. 1.
The number in the figure explanation:
1, valve body; 2, water intake; 3, water outlet; 4, arc is rectangular; 5, ball plug; 6, block; 7, curve bath; 8, sealing gasket.
Embodiment
Below in conjunction with Figure of description and specific embodiment, the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of DRV door of the present utility model, the water intake 2 and the water outlet 3 that comprise valve body 1 and valve body 1 two ends, water intake 2 places are provided with the guide groove assembly, hollow cavity and end that the guide groove assembly extends to valve body 1 inside are provided with limit assembly, the guide groove component internal is provided with movable ball plug 5, and ball plug 5 is provided with water intake 2 contacting points the curve bath 7 matched with ball plug 5.Check valve of the present utility model is provided with guide groove assembly and ball plug 5 in the cavity of valve body 1, and ball plug 5 is also the arc close contact with water intake 2, can effectively prevent the reverse flow of current, when ball plug 5 contacts with water intake 2, area is less, when flow reversal is flowed, the sound produced is less, can effective noise reduction function.
In the present embodiment, be provided with sealing gasket 8 on curve bath 7.Sealing gasket 8 can effectively prevent aqueous reflux, and can effectively alleviate the impact of 5 pairs of water intakes 2 of ball plug, reduces noise.
In the present embodiment, the guide groove assembly comprises two symmetrically arranged arcs rectangular 4.
In the present embodiment, limit assembly is the block 6 that is arranged on guide groove assembly end.
In the present embodiment, valve body 1 is one-body molded with the guide groove assembly.Integrated setting, the stability of increase structure, increase its working life.
Working procedure: when the current proper flow, current rush the left end to valve by ball plug 5, water enters into the cavity in valve body 1 from water intake 2, from water outlet 3, flow out, when current change direction, ball plug 5 is under the impact of current again, slide into water intake 2 along the guide groove assembly, rely on ball plug 5 to contact with the curve bath 7 of water intake 2, water seal is lived, make it no longer mobile.
To the above-mentioned explanation of the disclosed embodiments, make professional and technical personnel in the field can realize or use the utility model.Multiple modification to these embodiments will be apparent for those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from spirit or scope of the present utility model realization in other embodiments.Therefore, the utility model will can not be limited to these embodiments shown in this article, but will accord with principle disclosed herein and features of novelty the widest consistent scope.
