Description

Technical Field

[0001] The utility model relates to the technical field of gate valves, and in particular to a gate valve for preventing material accumulation. Background Art

[0002] A gate valve that prevents material accumulation can effectively reduce the problem of material accumulation in the valve through design and technical means, ensuring the normal operation of the valve and the smooth flow of the fluid.

[0003] The patent with patent announcement number CN 216590023 U discloses a gate valve for preventing material accumulation, including a hydraulic rod, a hydraulic rod sleeve, a hydraulic gate valve upper frame, a hydraulic gate valve frame, and a hydraulic gate valve gate, wherein the lower end port of the hydraulic gate valve gate is an angled port, and the groove of the lower frame of the hydraulic gate valve matched therewith is an L-shaped groove in cross section, a triangular support block is arranged in the L-shaped groove of the lower frame of the hydraulic gate valve, and the angled port at the lower end of the hydraulic gate valve gate is matched with the triangular support block, and the matching interface is an inclined surface.

[0004] However, during the use of the gate valve, dirt and grime may accumulate over time, resulting in the valve not being able to operate smoothly. Through the coordination between the angled ports, support blocks and other components, it is difficult to ensure the smooth flow of the medium, avoid the accumulation and scaling of dirt, and maintain the normal operation of the valve. Therefore, we propose a gate valve that prevents material accumulation. Utility Model Content

[0005] The utility model provides a gate valve for preventing material accumulation, which solves the problem of a gate valve for preventing material accumulation in the related technology.

[0006] The technical solution of the utility model is as follows: the utility model is a gate valve for preventing material accumulation, comprising a gate valve, a cylinder is fixedly connected to the top of the gate valve, an anti-accumulation device is arranged on the side of the gate valve, the anti-accumulation device comprises a valve seat, the side of the valve seat is fixedly connected to the side of the gate valve, the top of the valve seat is fixedly connected to a motor, a threaded rod is fixedly connected to the output shaft of the motor, a threaded sleeve is threadedly connected on the circumferential surface of the threaded rod, a limiting rod is fixedly connected to the top of the motor, an end of the limiting rod away from the motor passes through the bottom of the threaded sleeve, and a hanging plate is fixedly connected to the side of the threaded sleeve.

[0007] According to the above technical solution, there are two motors, threaded rods and threaded sleeves, and they are symmetrical to each other along the vertical center axis of the gate valve. The hanging plate is located on the inner wall of the gate valve and is provided in two groups, which is conducive to the simultaneous operation of both sides. The inner walls on both sides of the gate valve can be scraped at the same time to remove dirt.

[0008] According to the above technical solution, the hanging plate is set to a rectangular shape. There are two hanging plates, which are symmetrical to each other along the vertical center axis of the plug valve. The rectangular shape makes the contact area of ​​the hanging plate larger, and most of the dirt can be scraped off at one time.

[0009] When the cam is in the air, the cam is moved upwards to move the piston in the hydraulic cylinder to move upwards, and the piston movement pushes the liquid inside to move, and the liquid inside will push the round rod at the other end out, and the round rod movement will drive the moving plate to move, and the moving plate is located on the inner wall of the gate valve, and the moving plate will scrape back and forth on the top of the inner wall of the gate valve to scrape off the dirt on the top of the gate valve, so as to effectively prevent the material from accumulating on the top of the gate valve, and avoid the poor operation or blockage of the valve caused by the accumulation.

[0010] According to the above technical solution, an end of the push rod away from the hydraulic cylinder is fixedly connected with an inclined block, and the inclined block is located on the displacement track of the extrusion rod. The design of the inclined block is conducive to the extrusion of the extrusion rod.

[0011] According to the above technical solution, a spring is fixedly sleeved on the circumferential surface of the push rod, and one end of the spring away from the push rod is fixedly connected to the side of the hydraulic cylinder. The design of the spring is conducive to automatic reset of the extrusion rod when it is not squeezed.

[0012] According to the above technical solution, the movable plate is located on the inner wall of the gate valve, a shovel plate is fixedly connected to the top of the hanging plate, and a pressure gauge is provided on the side of the cylinder. The design of the shovel plate is conducive to scraping the inner wall of the gate valve when the hanging plate moves up and down, thereby enhancing the cleaning effect.

[0013] The working principle and beneficial effects of the utility model are:

[0014] 1. The utility model realizes that when material accumulates on the inner wall of the gate valve, the motor is started and the rotation of the motor drives the threaded rod to rotate. The rotation of the threaded rod drives the threaded sleeve to move up and down. The up and down movement of the threaded sleeve drives the hanging plate to move up and down. The up and down movement scrapes the inner wall of the gate valve to clean the dirt on both sides of the inner wall of the gate valve, thereby preventing the accumulation of materials on both sides of the valve, ensuring the smooth flow of the medium, avoiding the occurrence of poor flow or blockage, avoiding the accumulation and scaling of dirt, and maintaining the normal operation of the valve.

[0015] 2. The utility model realizes that the upward and downward movement of the hanging plate drives the vertical rod and the extrusion rod to move up and down through the mutual cooperation between the hydraulic cylinder, the push rod, the vertical rod, the extrusion rod and other components inside the anti-accumulation equipment. The extrusion rod will squeeze the inclined block in the process of moving upward. The extrusion of the inclined block will drive the push rod to move. The movement of the push rod will squeeze the piston inside the hydraulic cylinder to move. The movement of the piston will push the internal liquid to move. The movement of the internal liquid will push out the round rod at the other end. The movement of the round rod will drive the movement of the moving plate. The moving plate is located on the inner wall of the gate valve. The movement of the moving plate will scrape back and forth on the top of the inner wall of the gate valve to scrape off the dirt on the top of the gate valve, so as to effectively prevent the material from accumulating on the top of the gate valve and avoid poor operation or blockage of the valve due to accumulation.

[0026] There are two motors 32, threaded rods 33, and threaded sleeves 34, which are symmetrical to each other along the vertical center axis of the gate valve 1. The hanging plate 36 is located on the inner wall of the gate valve 1 and is provided with two groups, which is conducive to the simultaneous operation of both sides. The inner walls of both sides of the gate valve 1 can be scraped at the same time to remove dirt.

[0027] The hanging plate 36 is arranged in a rectangular shape. Two hanging plates 36 are arranged and are symmetrical to each other along the vertical center axis of the gate valve 1. The rectangular shape makes the contact area of ​​the hanging plate 36 larger and most of the dirt can be scraped off at one time.

[0028] In this embodiment, when material accumulates on the inner wall of the gate valve 1, the motor 32 is started, and the rotation of the motor 32 drives the threaded rod 33 to rotate.
