Description
Technical field
The utility model relates to field of check valves, is specially a kind of check vavle device.
Background technique
Safety check is a kind of valve class device commonly used, and its principle is to rely on the strength of media flow to realize opening and closing, to prevent the refluence of medium.Safety check is mainly used on the pipeline of medium one-way flow, only allows medium to flow to a direction.Safety check comprises valve body and the valve plate that is arranged in valve body, and the check valve structure of existing technology is simple, contains the medium of solid sundries for some; Solid sundries in the medium can hinder valve plate and close; Cause the safety check can't proper functioning, and when there not being media flow in the pipeline during gassy, valve plate can undesired opening under gas pressure; Cause safety check non-return effect to lose efficacy, make the pipeline medium occur refluxing.
The model utility content
The utility model purpose provides a kind of check vavle device, receives undesired the opening of gas pressure effect meeting in the pipeline to solve existing technology safety check valve plate, the safety check valve plate close be prone to be obstructed problem.
In order to achieve the above object, the technological scheme that the utility model adopted is:
A kind of check vavle device includes the valve body with horizontal cavity, it is characterized in that: said valve body top inner wall is provided with the last arc seat of shape and valve body top inner wall coupling; The valve body bottom interior wall is provided with the arc lower seat of shape and valve body bottom interior wall coupling, and upper and lower arc seat lateral alternate certain distance, also comprises the valve plate that tilts to place the valve body cavity; Said valve plate top one-way rotation is connected on the arc seat, and the valve plate bottom is pressed on behind the arc lower seat valve body cavity is cut off, and is positioned at valve plate and opens on the valve body top inner wall of direction one side and also be provided with swivel base; Be rotatablely equipped with push rod on the swivel base, said push rod one end is hinged on the valve plate, and the push rod the other end stretches out from the valve body cavity; Said valve body bottom outer wall is provided with hinged seat; Be hinged with turning handle on the hinged seat, said turning handle pommel is hinged with pull bar, is positioned on the valve body bottom interior wall of valve plate closing direction one side also to be provided with draw-bar seat; Be provided with slide opening in the draw-bar seat; Said pull bar stretches into valve plate closing direction one side in the valve body cavity from the slide opening of draw-bar seat, and the rod end of pull bar is connected with claw, is connected with the deck that supplies pull bar rod end claw to snap on the said valve plate.
The utility model is simple in structure, is easy to realize.Be connected with swivel base on the valve interior wall, be rotatably installed on the swivel base in the middle of the push rod, push rod one end is hinged on the valve plate; The other end stretches out valve body; If not closed fully under the influence of valve plate solid sundries in medium, can promote valve plate through push rod and close, make safety check valve plate return in time.Be hinged with turning handle on the hinged seat that is provided with on the valve body bottom outer wall, the pull bar that the turning handle pommel connects stretches in the valve body cavity, and the pull bar rod end is connected with claw; Be connected with deck on the valve plate; When not having media flow in the pipeline, can drive pull bar through turning handle and move down, the claw on the pull bar is stuck on the deck; Thereby fix valve plate, to prevent the excessive undesired valve plate of opening of gas pressure in the pipeline.The utility model has solved the problem that the safety check valve plate can not in time be closed effectively, and when safety check is not worked, can effectively improve the sealing of valve plate, and then has improved the unidirectional make-break capacity of safety check.
