    Description Spring ball check valve with good sealing Technical field The invention relates to a spring ball check valve.
    More specifically, the invention relates to a spring ball check valve with good sealing, which belongs to the technical field of the spring ball check valve.
    Background Art The spring loaded ball check valve only needs to turn 90 degrees and a small torque to connect the flow of fluid, upon releasing the valve handle, the valve will rebound and reset. automatically under the action of the spring.
    The current spring loaded ball check valve often does not have a good seal when connected to the water pipe.
    A technician wraps a layer of sealing tape over the thread of the flange where the ball valve connects to the pipe, then connects it to the pipe connection end to prevent water from overflowing.
    However, the aging and erosion of the sealing tape will gradually thin out when used for a long time, causing further deterioration of the pipe sealing.
    At the same time, the sealing tape will flow with the water flow in the pipe and affect the water quality. Summary of the Invention The invention relates to a spring-loaded ball check valve with good sealing to solve the technical problem of the prior art.
    The current spring loaded ball check valve often does not have a good seal when connected to the water pipe. A technician wraps a layer of sealing tape over the thread of the flange where the ball valve connects to the pipe, then connects it to the pipe connection end to prevent water from overflowing. However, the aging and erosion of the sealing tape will gradually thin out when used for a long time, causing further deterioration of the pipe sealing. At the same time, the sealing tape will flow with the water flow in the pipe and affect the water quality.
    In order to solve the above technical problems, the present invention provides the following technical solutions: The invention describes a spring ball check valve with good sealing, comprising a valve body, a flange provided at one end of the valve. valve body, a return spring and a push handle provided on the valve body, threads provided on the flange, a limit chute provided on the valve body, a gear plate provided in the limit chute, the plate to gears meshing with a gear, the upper end of the gear fixedly connected to the rotating rod, the rotating rod passing through the upper end of the valve body and fixedly connected to a handle, the lower end of the gear plate fixedly connected to a limit plate, the lower end of the limit chute fixedly connected to a telescopic plate, a spring fixedly connected inside the plate telescopic. According to a preferred embodiment, an anti-slip pattern is provided on said handle.
    In a preferred embodiment, said limit plate is arcuate, and said limit plate is provided with a slider at the end remote from the gear plate.
    In a preferred embodiment, there are four limit plates and limit chutes, and these limit plates are matched to each other.
    According to a preferred embodiment, a sealing sleeve is connected in a fixed manner at the level of the articulation between said rotary rod and said valve body.
    In a preferred embodiment, one end of the telescopic plate near the limit plate is fixedly connected with a pad.
    The beneficial effects of the present invention are as follows: The gear is driven by the handle and the rotating rod, the gear plate is driven by the gear, the limit chute is also driven. This could prevent water from entering the threaded connection of the flange when water passes through the connection of the flange, in order to tighten the spring loaded ball check valve.
    The slider can be easily adapted when connecting with the flange and the pipe, the telescopic plate and the spring can be used to protect the limit chute to prevent water pressure from generating an impulse towards the limit chute.

Obviously, the described embodiments are only part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts are within the scope of protection of the present invention. Embodiment: Referring to Figures 1, 2 and 3, the invention describes a spring-loaded ball check valve with good sealing, comprising a valve body 1, a flange 2 provided at one end of the body valve 1, a return spring 3 and a push handle 4 provided on the valve body 1, threads 5 provided on the flange 2, the threads 5 intended to make a fixed connection with the pipe, a limit chute 8 provided on the valve body 1, a gear plate 10 provided in the limit chute 8, the limit chute 8 having a protective function, the gear plate 10 meshing with a gear 9,
    the upper end of the gear 9 fixedly connected to the rotating rod 6, the rotating rod 6 passing through the upper end of the valve body | and fixedly connected to a handle 16, the rotation of the handle 16 causing the rotation of the gear 9, the lower end of the gear plate 10 fixedly connected to a limit plate 11, the lower end of the limit chute 8 fixedly connected to a telescopic plate 13, a spring 14 fixedly connected inside the telescopic plate 13, the spring 14 causing the restoration of the telescopic plate 13.
    There are four limit plates 11 and limit chutes 8, and these limit plates 11 are matched to each other providing a good seal. An anti-slip pattern 17 is provided on the handle 16, which is convenient for turning the handle 16. One end of the telescopic plate 13 near the limit plate 11 is fixedly connected with a pad 15, the pad 15 protects against damage. damage caused by friction. A sealing sleeve 7 is connected in a fixed manner at the level of the articulation between said rotary rod 6 and said valve body 1, the sealing sleeve 7 has the effect of maintaining the seal. The limit plate 11 is arc-shaped, and the limit plate 11 has a slider 12 at the far end of the gear plate 10, the slider 12 makes the contact more suitable and prevents abrasion .
