Description

Technical Field

[0001] This utility model relates to the field of check valve technology, specifically a check valve structure for unloading from ships and trucks. Background Technology

[0002] A check valve, or loading / unloading disconnect valve, is a type of valve used to prevent fluid backflow. It is primarily used in ships and vehicles to ensure that fluid flows in only one direction during loading and unloading, thus avoiding damage caused by backflow.

[0003] Traditional check valves mostly use a spring structure for reset. During use, as the spring force weakens, the valve body is prone to repeated reciprocating reset, which in turn affects the normal operation of the check valve. Summary of the Invention

[0004] The purpose of this invention is to solve or at least alleviate the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a check valve structure for unloading ships and trucks, comprising a valve body, a control component installed on the outer wall of the valve body, and two interconnected conical cavities opened on the inner wall of the valve body. A valve core assembly is installed on the inner wall of each of the two cavities. A drive component connected to the control component is installed at the midpoint of the inner wall of the valve body. A liquid flow direction sensor is installed on the outer wall of the drive component. Flanges are fixedly connected to both ends of the valve body.

[0006] By adopting the above structure, the valve body facilitates the delivery of liquid, the valve core assembly in the cavity facilitates the control of the opening and closing of the cavity, the control component facilitates the control of the drive component, the control component facilitates the direct actuation of the two valve core assemblies, the liquid flow direction sensor facilitates the control of the liquid flow direction in the valve body, and the flange facilitates the connection of the auxiliary valve body to the liquid delivery pipe.

[0007] Optionally, the valve core assembly includes a guide frame fixedly connected to the inner wall of the cavity, and the valve core is slidably connected to the inner wall of the guide frame.

[0008] By adopting the above structure, the guide frame facilitates the sliding installation of the auxiliary valve core, which has a frustum-shaped structure.

[0009] Optionally, the drive assembly includes a drive housing fixedly connected to the inner wall of the valve body, and the liquid flow direction sensor is fixedly connected to the drive housing.

[0010] By adopting the above structure, the liquid flow direction sensor can be easily installed through the drive box, and the liquid flow direction sensor can be easily monitored in real time for the liquid flow direction in the valve body.

[0011] Optionally, the outer walls on both sides of the drive box are provided with circular openings, and the inner walls of the two circular openings are slidably connected with drive frames. The drive frames are T-shaped structures, and one end of each drive frame is fixedly connected to a valve core.

[0012] By adopting the above structure, the drive frame can be easily connected to the valve core, thereby facilitating the movement of the drive frame to drive the valve core and control the opening and closing of the valve body.

[0013] Optionally, the inner wall of the drive box is fixedly connected to two fixed brackets, and the inner walls of the two fixed brackets are rotatably connected to the same bidirectional screw. Both drive brackets are screwed to both ends of the bidirectional screw. A worm gear is fixedly connected at the midpoint of the bidirectional screw, and a worm that meshes with the worm gear is rotatably connected to the inner wall of the top of the drive box.

[0014] By adopting the above structure, the bidirectional screw can be easily installed by setting the fixing frame. When the bidirectional screw rotates, it directly drives the two drive frames to move towards or away from each other. When the worm rotates, it directly drives the worm wheel to drive the bidirectional screw to rotate.

[0015] Optionally, the control assembly includes a control box fixedly connected to the valve body, and a servo motor is fixedly connected to the inner wall of the control box, with the output shaft of the servo motor fixedly connected to a worm gear.

[0016] By adopting the above structure, the servo motor can be easily installed through the control box. When the servo motor starts, it directly drives the worm gear to rotate, which in turn drives the worm wheel to drive the bidirectional screw to rotate.

[0017] Optionally, a plurality of equally spaced heat dissipation holes are provided on one side of the outer wall of the control box, and a controller is fixedly connected to the top outer wall of the control box, and the controller is electrically connected to the servo motor and the liquid flow direction sensor.

[0018] By adopting the above structure, the heat dissipation holes on the control box facilitate the cooling of the auxiliary servo motor, and the controller settings facilitate the control of electrical components.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This utility model sets two valve core assemblies in the valve body. The valve core assemblies facilitate the control of the on / off state at both ends of the valve body. The cooperation between the drive assembly and the control assembly facilitates the adjustment and control of the two valve core assemblies, improves the stability of the two valve core assemblies, and solves the problem of poor stability of existing check valves affecting the normal delivery of liquids.

[0021] This invention features a liquid flow direction sensor installed on the drive housing. This sensor facilitates real-time monitoring of the liquid flow direction in the valve body. When the liquid flow direction changes, the control component directly adjusts the drive component to drive the two valve core assemblies to close the valve body, thus effectively preventing liquid backflow.

Both outer walls of the drive housing 15 have circular openings, and the inner walls of both openings are slidably connected to drive frames 12. The drive frames 12 have a T-shaped structure, and one end of each drive frame 12 is fixedly connected to two valve cores 8. The drive frames 12 facilitate connection with the valve cores 8, thereby facilitating the flow of liquid through the drive frames 12.
