Abstract
The invention relates to a check valve which comprises a valve body and a valve plate matched with the valve body. A medium channel for circulating media is formed in the valve body, the valve plate is arranged in the medium channel, the valve body is provided with a fitting portion fitting with the valve plate, the fitting portion is provided with a fitting surface which is vertically inclined upwards, and the valve plate is attached on the fitting surface only under the action of gravity when closed. A surface of the valve body matched with the valve plate has a certain inclination angle, so that the valve plate can be automatically closed through the gravity without any external acting force, and the check valve is simple in structure, convenient to operate and low in machining cost.
Description
Technical field
the present invention relates to a kind of safety check.
Background technique
safety check is that a kind of dependence medium itself flows and automatic open and close valve plate, is used for preventing the valve that medium flows backwards.To different valves; The mode of closing of valve plate has nothing in common with each other; Close but special mechanism's operation valve plate generally all need be set, whether its structure complicacy that will compare on the one hand can close the place that puts in place and need consider when also being design with valve plate on the other hand.Therefore, very need need be a kind of simple in structure at present, closes stable safety check.
Summary of the invention
the purpose of this invention is to provide a kind of safety check.
For achieving the above object, the technological scheme that the present invention adopts is:
a kind of safety check; Comprise valve body, the valve plate that matches with described valve body; Be formed for the medium channel of circulation medium in the described valve body, described valve plate is arranged in the described medium channel, and described valve body has the sticking part that fits with described valve plate; Described sticking part has a faying surface; Described faying surface settings that on vertically, be inclined upwardly, and when described valve plate is in closed condition, described valve plate is fitted on the described faying surface under action of gravity.
preferably, the angle of inclination of described faying surface is the 3-7 degree.
preferably; Has a circle groove on the described faying surface; Be provided with the protuberance that is complementary with described groove near described faying surface one side on the described valve plate, when described valve plate was in closed condition, described protuberance was stuck in the described groove.
preferably, described valve body is provided with at least one hook, is connected with rotating shaft on the described valve plate, and when described valve body matched with valve plate, described rotating shaft hung in the described hook.
further preferably, described hook is provided with two.
further preferably, described hook and the moulding of valve body integrally casting.
further preferably, described rotating shaft is a stainless steel bar.
preferably, described valve plate is coated with rubber layer or adopts rubber material to process.
Because the technique scheme utilization, the present invention compared with prior art has advantage:
the present invention is through being provided with certain tilt angle with the face that matches with valve plate on the valve body; Make that valve plate also can closing through gravity automatically under need not be by the situation of any applied external force; It is simple in structure, and is easy to operate, and processing cost is low.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention;
accompanying drawing 2 is the structural representation of valve plate among the present invention.
wherein: 1, valve body; 10, medium channel; 11, sticking part; 110, faying surface; 12, groove; 13, hook; 2, valve plate; 20, protuberance; 3, rotating shaft.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described:
comprise valve body 1, the valve plate 2 that matches with valve body 1 like Fig. 1, a kind of safety check shown in 2, are formed for the medium channel 10 of circulation medium in the valve body 1, and valve plate 2 is arranged in the medium channel 10.In the present embodiment: valve body 1 has the sticking part 11 that fits with valve plate 2, and sticking part 11 has a faying surface 110, faying surface 110 settings that on vertically, be inclined upwardly, and the angle of inclination of its faying surface 110 is the 3-7 degree, spends as 5.Like this, do not having under the situation of circulation medium, valve plate 2 self also can be fitted on the faying surface 110 because of gravity, closes automatically.
in addition; On faying surface 110, has a circle groove 12; Be provided with the protuberance 20 that is complementary with groove 12 near faying surface 110 1 sides on the valve plate 2, like this, when valve plate 2 is fitted in 110 last times of faying surface; Protuberance 20 can be stuck in the groove 12, guarantees the sealing after valve plate 2 is closed.Valve plate 2 can be coated with rubber layer or directly adopt rubber material to process on its surface, can reduce the setting of seal ring through rubber layer.
the foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to let the personage who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed within protection scope of the present invention.
