Abstract
The utility model discloses a double-clip type check valve which comprises an annular valve body. A spindle and a guide pillar are fixedly arranged on the annular valve body in the diameter direction in a sealing mode. A double-clip type valve plate is arranged on the spindle in a rotating mode. A torsion spring is fixedly arranged on the guide pillar in a sleeved mode. The annular valve body is an annular valve body with a step. The diameter of the double-clip type valve plate is larger than the minor diameter in the annular valve body and is smaller than the major diameter in the annular valve body. A groove is formed in the step, wherein the groove corresponds to the double-clip type valve plate. A sealing ring is arranged at a position of an opening of the groove. Reinforcing ribs are connected between the guide pillar and the inner wall of the valve body. According to the double-clip type check valve, the guide pillar is prevented from fracturing when the check valve is used due to the arrangement of the reinforcing ribs between the guide pillar and the valve body, dumping of the check valve is avoided, the service life of the check valve is prolonged, and the sealing performance is good.
Description
Technical field
The utility model relates to valve technology field, relates in particular to a kind of Wafer Check Valves.
Background technique
Safety check claims again one-way valve or check valve, and its effect is to prevent that the medium in pipeline from flowing backwards, and open-shut device is opened voluntarily or closes by media flow and strength, to prevent that valve that medium flows backwards is on safety check.Safety check belongs to the self-acting valve class, is mainly used on the pipeline of medium one-way flow, only allows medium to flow to a direction, to try to avert accidents.
The flap of safety check is opened under fluid pressure action, and fluid flows to outlet side from suction side.During lower than outlet side, flap autoshutdown under the factor effects such as fluid pressure difference, gravity own flows backwards to prevent fluid when suction side pressure.If poor sealing between valve plate and valve body, safety check can lose the effect of himself, causes medium to flow backwards.
The model utility content
The utility model purpose is exactly in order to make up the defective of prior art, a kind of Wafer Check Valves to be provided.
The utility model is achieved through the following technical solutions:
A kind of Wafer Check Valves, include annular valve body, fix and be sealed and installed with rotating shaft and guide pillar on described annular valve body diametric(al), be rotatablely equipped with the wafer type valve plate in described rotating shaft, be set with and be fixed with torsion spring on described guide pillar, the feeler Elastic Contact at described torsion spring two ends is on described wafer type valve plate, when described torsion spring is in relaxed state, described wafer type valve plate is the V font, and described annular valve body is the annular valve body with step; The diameter of described wafer type valve plate is greater than the path in described annular valve body and less than its large footpath, have the groove corresponding with the wafer type valve plate on described step, described slot opening place is provided with seal ring, is connected with stiffening rib between described guide pillar and valve interior wall.
Described wafer type valve plate integral body is circular.
The utility model has the advantages that: the utility model prevents safety check in use by increase stiffening rib between guide pillar and valve interior wall, and the guide pillar fracture causes safety check to be scrapped, and extends the working life of safety check, good airproof performance.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of Wafer Check Valves, include annular valve body 1, fix and be sealed and installed with rotating shaft 2 and guide pillar 3 on described annular valve body 1 diametric(al), be rotatablely equipped with wafer type valve plate 4 in described rotating shaft 2, be set with and be fixed with torsion spring 5 on described guide pillar 3, the feeler Elastic Contact at described torsion spring 5 two ends is on described wafer type valve plate 4, when described torsion spring 5 is in relaxed state, described wafer type valve plate 4 is the V font, and described annular valve body 1 is the annular valve body with step; The diameter of described wafer type valve plate 4 is greater than the path in described annular valve body 1 and less than its large footpath, have the groove corresponding with wafer type valve plate 47 on described step, described groove 7 openings are provided with seal ring 6, are connected with stiffening rib 8 between described guide pillar 2 and valve body 1 inwall.
Described wafer type valve plate 4 integral body are circular.
