Description
Technical field
The utility model relates to a kind of ball valve, especially relates to a kind of close ball valve of elastomeric perseverance that is provided with.
Background technique
The application of ball valve is very general, and all needing to use ball valve, traditional ball valve as water pipe, oil pipe, tracheae etc. is all to adopt ball sealer is set in valve body, utilizes the switching of ball sealer to control the switching of pipeline.The existing major defect of traditional ball valve is that the long-term use due to ball sealer easily causes it to leak or leak gas because of wearing and tearing.Thereby affect its working life.
Summary of the invention
The purpose of this utility model is to provide a kind of reasonable in design for the existing defective of above-mentioned ball valve, can increase the service life increase sealability be provided with the permanent close ball valve of elastomer.
In order to achieve the above object, the utility model is mainly realized by the following technical solutions, the utility model mainly is comprised of ball valve body, the two ends water outlet of ball valve body is respectively equipped with male connection, male connection matches with the internal thread nut that matches, connecting water pipe on two water outlets.The both sides of ball valve body are respectively equipped with ball bowl seat, be respectively equipped with the ball bowl in ball bowl seat, the centre of ball valve body is provided with ball sealer, two ball bowls are with the ball sealer inclusion, ball sealer is provided with groove, groove is provided with the ball valve swing arm, and an end of ball valve swing arm stretches out above valve body, and the end of ball valve swing arm is provided with spanner.Rear portion at the ball bowl also is respectively equipped with spring support, is provided with elastomer in spring support.
The utility model compared with prior art has following obvious advantage and progress.The ball bowl back of the utility model in valve body adds spring support and elastomer, strengthened the sealing between ball bowl and ball sealer, after the ball bowl was worn, the elastomer of being located in spring support will automatic impaction ball bowl, guarantee the sealing between ball bowl and ball sealer, prevent from leaking.
The utility model is applicable to ball valve.
Below in conjunction with the drawings and specific embodiments, the utility model is done the description of further detail.
