Abstract
The utility model discloses a double-clip type disc type check valve with good sealing performance. The double-clip type disc type check valve with the good sealing performance comprises an annular valve body. A revolving shaft and a guiding column are fixed and installed on the annular valve body in a sealed mode in the diameter direction, a double-clip type valve plate is installed on the revolving shaft in a rolling mode, and a torsional spring is sleeved and fixed on the guiding column. Feelers arranged at two ends of the torsional spring are contacted with the double-clip type valve plate in an elastic mode, and the annular valve body is provided with a step. A groove corresponding to the double-clip type valve plate is formed in the step, and a sealing ring is arranged at an opening of the groove. The double-clip type disc type check valve with the good sealing performance is simple in structure and procedure of manufacture and installation. The double-clip type valve plate is contacted with the groove of the valve body and the sealing ring is used for sealing, so that the sealing performance is improved, the function of preventing backflow is good and safety is high.
Description
Technical field
The utility model relates to valve technology field, relates in particular to a kind of wafer type dish check valve of good airproof performance.
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 type dish check valve of good airproof performance to be provided.
The utility model is achieved through the following technical solutions:
A kind of wafer type dish check valve of good airproof performance, 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, and described annular valve body is the annular valve body with step; The diameter of described wafer type valve plate has the groove corresponding with the wafer type valve plate greater than the path in described annular valve body and less than its large footpath on described step, described slot opening place is provided with seal ring.
When described torsion spring was in relaxed state, described wafer type valve plate was the V font, and described wafer type valve plate integral body is circular.
The utility model has the advantages that: the utility model is simple in structure, makes installation procedure simple, contacts with the groove type of valve body by the wafer type valve plate, with the seal ring sealing, has improved sealability, and anti-backflow effect is good, safe.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
