Description

Technical Field

[0001] This utility model relates to the field of electric gate valve technology, and more specifically, to an electric gate valve. Background Technology

[0002] An electric valve is a valve controlled by an electric actuator, thereby realizing the opening and closing of the valve. It is generally divided into two parts: the upper part is the electric actuator and the lower part is the valve. The electric actuator controls the opening and closing of the valve.

[0003] With the development of society, not only are there more water pipes in cities, but also more and more water pipes for rural households. In order to make convenient and rational use of water resources, electric gate valves are often installed on water pipes. When water is needed, the valve is opened to allow water to flow in the pipe, and when the valve is closed, the water flow in the pipe is cut off.

[0004] With the development of valves, different shapes, sizes, and application characteristics have emerged, but the basic principle remains the same. The advent of valves has facilitated people's management and control of water resources.

[0005] Since rural households often rely on wells dug in the mountains for water, and the water in these wells may contain some mud, if the gate valve is closed for too long, the mud may accumulate on the gate plate. When there is too much mud, the valve may become unable to open.

[0006] Meanwhile, the conditions inside the well are complex, and small debris such as dry branches and leaves are often pumped away with the water, causing them to enter the water pipes and cause blockages.

[0007] Therefore, it is necessary to provide a new electric gate valve to solve the above-mentioned technical problems. Utility Model Content

[0008] The purpose of this utility model is to provide an electric gate valve that is easy to use, has high movement precision, and can better ensure the personal safety of workers.

[0009] The embodiments of this utility model are implemented as follows:

[0010] An electric gate valve, comprising:

[0011] The valve body has a gate plate installed inside it, and the gate plate has an installation groove A. The gate plate has an installation cavity inside it, and the other side of the gate plate has an installation groove B. The gate plate is an alloy component that blocks the flow of water. By extending the gate plate, the water flow in the pipe can be cut off. When the gate plate is retracted into the cavity, the pipe can be connected and the water flow can be allowed to pass through.

[0012] A sludge removal assembly, located on a gate plate, includes a rotary motor, gear A, a transmission rod, gear B, a threaded rod, gear C, a sludge removal plate, and a shock-absorbing spring. The rotary motor is fixedly connected to the mounting groove A, and gear A is fixedly connected to the output end of the rotary motor. A transmission rod is rotatably connected to the mounting cavity, and gears B are fixedly connected to both ends of the transmission rod. A threaded rod is rotatably connected to the mounting groove B, and gear C is fixedly connected to one end of the threaded rod. A threaded sludge removal plate is mounted on the threaded rod. The gate is equipped with a mud plate, and multiple shock-absorbing springs are fixedly connected between the mud plate and the inner wall of the installation groove B. When the gate is covered by mud in the water flow and cannot be opened, the rotary motor is started, which drives the transmission rod to rotate through gears A and B, and then drives the threaded rod to rotate through gears B and C. When the threaded rod rotates, it will drive the mud plate to move, push the mud, and make it soft. Then the valve can be opened normally, avoiding the problem that traditional electric gate valves cannot be opened normally due to mud in the water flow. This effectively improves the applicability of the valve to the installation environment.

[0013] A docking plate is mounted on the valve body and docks with a fastening plate. A loading assembly is installed between the docking plate and the fastening plate.

[0014] In some embodiments of this utility model, the docking plate is provided with multiple limiting grooves, and the inner top wall of the limiting groove is provided with a fixing groove. The limiting groove is connected with the locking block, and the fixing groove is connected with the docking block.

[0015] In some embodiments of this utility model, a fastening plate is installed on the docking plate, and multiple fixedly connected locking blocks are installed on the fastening plate. The top of each locking block has a positioning groove, and two fixedly connected telescopic springs are installed in the positioning groove. The top of each telescopic spring is fixedly connected to a docking block. When the fastening plate is pressed against the docking plate, the locking block will extend into the limiting groove. At this time, the limiting groove squeezes the docking block and the telescopic spring, causing the docking block to retract into the positioning groove. When the docking block moves to the bottom of the fixed groove, the telescopic spring will pop out the docking block due to the disappearance of the squeezing force of the limiting groove, causing the docking block to lock into the fixed groove, thus fixing the docking plate and the fastening plate.

[0016] In some embodiments of this utility model, a fixing component is installed on the docking plate and the fastening plate. The fixing component includes a fixing ring, a mounting base and a connecting rod. The docking plate and the fastening plate are both fixedly connected to the fixing ring, and the fixing ring is fixedly connected to the mounting base. The mounting base is connected to the connecting rod in a sliding manner. The fixing component limits the docking plate and the fastening plate to prevent the fastening plate from detaching from the docking plate.

[0017] In some embodiments of this utility model, the loading assembly includes an installation plate, a collection net, and a docking hole. The installation plate is slidably connected to the locking block through the docking hole, and the collection net is fixedly connected to the inner wall of the installation plate. When the gate valve is installed and in use, the installation plate is locked onto the locking block through the docking hole. Then, the fastening plate is moved by the connecting rod, the locking block is locked into the limiting groove, and the docking block is embedded into the fixing groove. At this time, the docking plate and the fastening plate cooperate to fix the installation plate. When water flows through, the collection net will block larger impurities such as dead branches and leaves in the water flow, avoiding the problem of subsequent pipeline blockage caused by dead branches and leaves, effectively improving the protection of the pipeline by the gate valve.

[0018] In some embodiments of this utility model, the valve body is fitted with a fixedly connected outer cover, and the top of the outer cover is fitted with two rotatably connected sealing caps. Since gate valves in rural areas are usually buried underground along with water pipes, and the air in the soil is relatively humid, it will corrode the electric gate valve and cause it to rust. The outer cover is added to protect the electric gate valve from corrosion, and the sealing caps can be opened to inspect the electric gate valve.

[0019] In some embodiments of this utility model, a fixedly connected receiving cavity is installed on the top of the valve body, and the diameter of the receiving cavity is the same as that of the gate. The gate can be retracted into the receiving cavity to expand the pipe and increase the water flow in the pipe.

[0020] In some embodiments of this utility model, a drive assembly is installed on the top of the receiving cavity. The drive assembly includes a fixed frame, a drive motor, a valve stem, and a handwheel. The fixed frame is fixedly connected to the top of the receiving cavity, and the drive motor is fixedly connected to the top of the fixed frame. The output end of the drive motor is fixedly connected to the valve stem, and the other end of the valve stem is fixedly connected to the gate. The handwheel is fixedly connected to the top of the drive motor. By turning on the drive motor, the valve stem is rotated, which in turn moves the gate up and down to complete the opening and closing of the valve. When the drive motor is damaged and the gate cannot be opened, the gate can be opened or closed manually by rotating the handwheel.

[0021] In some embodiments of this utility model, the gears B at both ends of the transmission rod are respectively engaged with gears A and C, and gears A, B and C are of the same size.

[0022] In some embodiments of this utility model, the outer cover is provided in two parts and fixed by bolts, and each of the sealing covers is equipped with a handle on the top.

[0023] The embodiments of this utility model have at least the following advantages or beneficial effects:

[0024] 1. When the gate valve is covered by mud in the water flow and cannot be opened, the present invention starts a rotary motor, which drives the transmission rod to rotate through gears A and B, and then drives the threaded rod to rotate through gears B and C. When the threaded rod rotates, it will drive the mud removal plate to move, push the mud and make it soft, and then the valve can be opened normally. This avoids the problem of traditional electric gate valves being unable to open normally due to mud in the water flow, and effectively improves the applicability of the valve to the installation environment.

[0025] 2. This utility model embodiment provides an electric gate valve that, after installation, has its mounting plate secured to the locking block via the mating hole. Then, the fastening plate is moved via the connecting rod, causing the locking block to engage in the limiting groove and the mating block to embed in the fixing groove. At this point, the mating plate and the fastening plate work together to fix the mounting plate. When water flows through, the collecting net blocks larger impurities such as dead branches and leaves, preventing subsequent pipe blockages caused by dead branches and leaves, effectively improving the gate valve's protection of the pipeline.

[0042] Example

[0043] Please see Figures 1 to 8 The present invention provides an electric gate valve, which includes: a valve body 1, a mud removal assembly 3 and a docking plate 6. A fixedly connected receiving cavity 11 is installed on the top of the valve body 1, and the diameter of the receiving cavity 11 is the same as that of the gate plate 2. The gate plate 2 is installed inside the valve body 1, and an installation groove A21 is opened on the gate plate 2. An installation cavity 22 is opened inside the gate plate 2, and an installation groove B23 is opened on the other side of the gate plate 2.

[0044] The sludge removal assembly 3 is located on the gate plate 2. The sludge removal assembly 3 includes a rotary motor 31, gear A32, transmission rod 33, gear B34, threaded rod 35, gear C36, sludge removal plate 37, and shock-absorbing springs 38. The rotary motor 31 is fixedly connected in the mounting groove A21, and the output end of the rotary motor 31 is fixedly connected to the gear A32. The transmission rod 33 is rotatably connected in the mounting cavity 22, and both ends of the transmission rod 33 are fixedly connected to the gear B34. The threaded rod 35 is rotatably connected in the mounting groove B23, and one end of the threaded rod 35 is fixedly connected to the gear C36. The threaded sludge removal plate 37 is threadedly connected on the threaded rod 35, and multiple fixedly connected shock-absorbing springs 38 are installed between the sludge removal plate 37 and the inner wall of the mounting groove B23. The gears B34 at both ends of the transmission rod 33 are respectively engaged with gears A32 and C36, and gears A32, B34, and C36 are the same size.

[0045] It should be noted that: Gate 2 is an alloy component that blocks the flow of water. By extending Gate 2, the water flow in the pipe can be cut off. When Gate 2 is retracted into the receiving cavity 11, the pipe can be connected and the water flow can be allowed to pass through.

[0046] It should also be noted that when the gate 2 is covered by mud in the water flow and cannot be opened, the rotary motor 31 is started, which drives the transmission rod 33 to rotate through gears A32 and B34. Then, through gears B34 and C36, the threaded rod 35 is rotated. When the threaded rod 35 rotates, it will move the mud removal plate 37, pushing the mud and making it soft. Then the valve can be opened normally. This avoids the problem of traditional electric gate valves being unable to open normally due to mud in the water flow. It effectively improves the applicability of the valve to the installation environment. At the same time, the shock-absorbing spring 38 provides shock absorption for the mud removal plate 37 and can also fix the mud removal plate 37 to prevent it from falling off the threaded rod 35.

[0047] refer to Figure 2 and Figure 3 As shown, a drive assembly 4 is installed on the top of the storage cavity 11. The drive assembly 4 includes a fixed frame 41, a drive motor 42, a valve stem 43, and a handwheel 44. The fixed frame 41 is fixedly connected to the top of the storage cavity 11, and the drive motor 42 is fixedly connected to the top of the fixed frame 41. The valve stem 43 is fixedly connected to the output end of the drive motor 42, and the other end of the valve stem 43 is fixedly connected to the gate plate 2. The handwheel 44 is fixedly connected to the top of the drive motor 42.

[0048] It should be noted that: by turning on the drive motor 42, it drives the valve stem 43 to rotate, and drives the gate 2 to move up and down to complete the opening and closing of the valve. When the drive motor 42 is damaged and the gate 2 cannot be opened, it can be manually turned by the handwheel 44 to open or close the gate 2.

[0049] refer to Figure 1 As shown, a fixedly connected outer cover 5 is installed on the valve body 1, and two rotatably connected sealing covers 51 are installed on the top of the outer cover 5. The outer cover 5 has two covers and is fixed by bolts, and each sealing cover 51 has a handle installed on its top.

[0050] It should be noted that since gate valves in rural areas are usually buried underground along with water pipes, and the air in the soil is relatively humid, it will corrode the electric gate valve and cause it to rust. The outer cover 5 is added to protect the electric gate valve and prevent it from being corroded. At the same time, the sealing cover 51 can be opened to inspect the electric gate valve.

[0051] refer to Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the docking plate 6 is installed on the valve body 1. The docking plate 6 has multiple limiting grooves 61, and the inner top wall of the limiting grooves 61 has a fixing groove 62. The docking plate 6 is equipped with a fastening plate 8, and the fastening plate 8 is equipped with multiple fixedly connected locking blocks 81. The top of the locking blocks 81 has a positioning groove 82, and two fixedly connected telescopic springs 83 are installed in the positioning groove 82. The top of the telescopic springs 83 is equipped with a fixedly connected docking block 84. The docking plate 6 and the fastening plate 8 are equipped with a fixing assembly 7. The fixing assembly 7 includes a fixing ring 71, a mounting base 72 and a connecting rod 73. The docking plate 6 and the fastening plate 8 are both equipped with fixedly connected fixing rings 71, and the fixing rings 71 are both equipped with fixedly connected mounting bases 72. The mounting bases 72 are connected by a sliding connecting rod 73.

[0052] The loading assembly 9 includes a mounting plate 91, a collection net 92, and a docking hole 93. The mounting plate 91 is slidably connected to the locking block 81 through the docking hole 93, and the collection net 92 is fixedly connected to the inner wall of the mounting plate 91.

[0053] It should be noted that when the fastening plate 8 is pressed against the mating plate 6, the locking block 81 will extend into the limiting groove 61. At this time, the limiting groove 61 will squeeze the mating block 84 and the telescopic spring 83, causing the mating block 84 to retract into the positioning groove 82. When the mating block 84 moves to the bottom of the fixing groove 62, the telescopic spring 83 will pop out the mating block 84 due to the disappearance of the squeezing force of the limiting groove 61, so that the mating block 84 is locked into the fixing groove 62, fixing the mating plate 6 and the fastening plate 8. The fixing component 7 limits the mating plate 6 and the fastening plate 8 to prevent the fastening plate 8 from detaching from the mating plate 6.

[0054] It should also be noted that: the mounting plate 91 is secured to the locking block 81 through the docking hole 93, and then the fastening plate 8 is moved by the connecting rod 73. The locking block 81 is engaged in the limiting groove 61, and the docking block 84 is embedded in the fixing groove 62. At this time, the docking plate 6 and the fastening plate 8 cooperate to fix the mounting plate 91. When water flows through, the collecting net 92 will block larger impurities such as dead branches and leaves in the water flow, avoiding the problem of subsequent pipeline blockage caused by dead branches and leaves, and effectively improving the protection of the pipeline by the gate valve.

[0055] The working principle of an electric gate valve is:

[0056] First, the electric gate valve is installed on the pipeline. Since gate valves in rural areas are usually buried underground along with water pipes, and the air in the soil is relatively humid, it will corrode the electric gate valve and cause it to rust. An outer cover 5 is added to protect the electric gate valve and prevent it from being corroded. At the same time, the sealing cover 51 can be opened to inspect the electric gate valve. Then, it is buried underground together with the outer cover 5. When water is needed or when the water supply is interrupted, the drive motor 42 is turned on, which drives the valve stem 43 to rotate and moves the gate plate 2 up and down to complete the opening and closing of the valve. When the drive motor 42 is damaged and the gate plate 2 cannot be opened, it can be manually turned by the handwheel 44 to open or close the gate plate 2.

[0057] When the fastening disc 8 is pressed against the mating disc 6, the locking block 81 extends into the limiting groove 61. At this time, the limiting groove 61 compresses the mating block 84 and the telescopic spring 83, causing the mating block 84 to retract into the positioning groove 82. When the mating block 84 moves below the fixing groove 62, the compressive force of the limiting groove 61 disappears, and the telescopic spring 83 pops the mating block 84 out, causing it to lock into the fixing groove 62, thus fixing the mating disc 6 and the fastening disc 8. The fixing component 7 limits the mating disc 6 and the fastening disc 8, preventing the fastening disc 8 from being stopped. Disconnect from the docking plate 6, and simultaneously, the mounting plate 91 is secured to the locking block 81 through the docking hole 93. Then, the fastening plate 8 is moved by the connecting rod 73, the locking block 81 is engaged in the limiting groove 61, and the docking block 84 is embedded in the fixing groove 62. At this time, the docking plate 6 and the fastening plate 8 cooperate to fix the mounting plate 91. When water flows through, the collecting net 92 will block larger impurities such as dead branches and leaves in the water flow, avoiding the problem of subsequent pipeline blockage caused by dead branches and leaves, effectively improving the protection of the pipeline by the gate valve.

[0058] Furthermore, when the gate 2 is covered by mud in the water flow and cannot be opened, the rotary motor 31 is started, which drives the transmission rod 33 to rotate through gears A32 and B34. Then, through gears B34 and C36, the threaded rod 35 is rotated. When the threaded rod 35 rotates, it will move the mud removal plate 37, pushing the mud and making it soft. Then the valve can be opened normally. This avoids the problem of traditional electric gate valves being unable to open normally due to mud in the water flow. It effectively improves the applicability of the valve to the installation environment. At the same time, the shock-absorbing spring 38 provides shock absorption for the mud removal plate 37 and can also fix the mud removal plate 37 to prevent it from falling off the threaded rod 35.

[0059] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
