Description

Technical Field

[0001] This utility model relates to the field of gate valve technology, specifically a novel gate valve. Background Technology

[0002] Gate valves, as a type of shut-off valve widely used in the industrial field, work by precisely controlling the opening and closing of the valve through the lifting and lowering movement of the gate, thereby realizing the flow or cut-off of the medium in the pipeline.

[0003] However, existing gate valve technology exhibits significant drawbacks when applied to liquid environments with high sediment content. Specifically, when the gate valve is open, the lower end of the valve plate easily becomes a sediment deposition area. With prolonged use, sediment accumulates, increasing in volume. This phenomenon can ultimately lead to serious consequences, such as the gate failing to close properly due to sediment obstruction, severely impacting the normal operation of the gate valve and the stable functioning of the pipeline system.

[0004] In view of the above problems, a new type of gate valve is needed for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a novel gate valve to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A novel gate valve, comprising a housing, with connecting pipes fixedly disposed at both ends of the housing surface, and a gate structure for closing the connecting pipes disposed inside the housing, the gate mechanism comprising a gate plate, a connecting groove, and a screw, the gate plate being movably engaged inside the housing, the connecting groove being disposed in the middle of the inner side of the gate plate, the screw being movably screwed onto the upper end of the housing via a bearing, and a collection mechanism for collecting impurities disposed at the lower end of the housing, the collection mechanism comprising a collection chamber, a fixing screw, and a flushing pipe, the collection chamber being fixedly disposed at the lower end of the housing, the fixing screw being disposed between the collection chamber and the housing, and flushing pipes being fixedly disposed on both sides of the surface of the collection chamber.

[0007] Preferably, the lower end of the shell is through-hole, so that the interior of the shell and the interior of the collection chamber are interconnected. The sand and soil remaining in the movement path of the gate will be pushed into the collection chamber for storage when the gate is closed.

[0008] Preferably, a first flange is fixedly provided at the end of the connecting pipe away from the shell, and a first mounting hole is provided on the outer surface of the first flange, so that the connecting pipe can be easily connected to the entire pipeline through the first flange.

[0009] Preferably, the outer surface of the screw is provided inside the connecting groove by a threaded connection, so that the rotation of the screw can drive the gate to move up and down. When the gate moves up, it can make the two connecting pipes connected, and vice versa.

[0010] Preferably, a second flange is fixedly installed at the end of the flushing pipe away from the collection chamber. A second mounting hole is provided on the outer surface of the second flange, and a sealing cap is provided on the outer side of the second flange through the second mounting hole. The flushing pipe of the collection chamber of this device needs to be connected through the second flange and the sealing cap to ensure that the flushing pipe is in a sealed state when the device is in normal use. Subsequently, this device is provided with two cleaning methods. If it is convenient to connect the pipe, pump body and clean water source, the operator can periodically remove the sealing cap and then connect the flushing pipe to the pump body, valve and clean water source through the second flange. In this way, the inside of the collection chamber can be flushed with clean water through the flushing pipe periodically.

[0011] The second cleaning method is to use the flushing pipe through the second flange to keep the cover sealed when it is inconvenient to connect the pipe, pump and clean water source. After the device has been used for a long time, the collection chamber can be disassembled manually, removed and then emptied for cleaning.

[0012] Preferably, a handwheel is fixedly provided at the upper end of the screw, which allows the screw to be rotated easily.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model has a collection chamber at the lower end of the traditional gate valve, which can be used to collect impurities. Each time the gate is opened and closed, these impurities can be automatically squeezed into the collection chamber for collection, so that the impurities will not block the gate and cause the gate to fail to close, thus improving the reliability and stability of the gate valve.

[0014] 2. The collection chamber of this device is also equipped with a flushing pipe, which facilitates cleaning of the inside of the collection chamber. By employing two different cleaning methods, it can adapt to different usage scenarios and conditions, ensuring that the collection chamber remains clean at all times and extending the service life of the gate valve.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 This utility model provides a technical solution: a novel gate valve, including a housing 1, with connecting pipes 2 fixedly provided at both ends of the surface of the housing 1, and a gate structure for closing the connecting pipes 2 provided inside the housing 1. The gate mechanism includes a gate plate 3, a connecting groove 4, and a screw 5.

[0019] A gate 3 is movably engaged inside the housing 1. A connecting groove 4 is provided in the middle of the inner side of the gate 3. A screw 5 is movably engaged with the upper end of the housing 1 via a bearing. The outer surface of the screw 5 is movably engaged with the connecting groove 4 via a thread. Thus, rotating the screw 5 drives the gate 3 to move up and down. When the gate 3 moves upward, it opens the connection between the two connecting pipes 2, allowing the medium to flow in the pipeline; conversely, moving the gate 3 downward closes the connecting pipes 2, cutting off the flow of the medium in the pipeline. A handwheel 11 is fixedly provided at the upper end of the screw 5, allowing the screw 5 to be easily rotated. Operators can easily control the gate 3 without using complicated tools.

[0020] The lower end of the housing 1 is equipped with a collection mechanism for collecting impurities. The collection mechanism includes a collection chamber 6, a fixing screw 7, and a flushing pipe 8. The collection chamber 6 is fixedly installed at the lower end of the housing 1, and the lower end of the housing 1 extends through it, so that the interior of the housing 1 and the interior of the collection chamber 6 are interconnected. Sand and soil remaining in the moving path of the gate 3 will be pushed into the collection chamber 6 for storage when the gate 3 is closed, effectively preventing the accumulation of mud and sand at the lower end of the gate 3.

[0021] A fixing screw 7 is provided between the collection chamber 6 and the shell 1. The collection chamber 6 can be easily fixed to the lower end of the shell 1 by fixing screw 7, and it is also convenient to disassemble and maintain the collection chamber 6 in the future.

[0022] A flushing pipe 8 is fixedly installed on both sides of the surface of the collection chamber 6. A second flange 10 is fixedly installed at the end of the flushing pipe 8 away from the collection chamber 6. A second mounting hole 14 is provided on the outside of the second flange 10, and a sealing cover 12 is installed through the second mounting hole 14 and screws. The flushing pipe 8 can be easily connected to external pipelines and pump bodies through the second flange 10, or directly connected to the sealing cover 12.

[0023] A first flange 9 is fixedly installed at the end of the connecting pipe 2 away from the shell 1. A first mounting hole 13 is opened on the surface of the first flange 9. The connecting pipe 2 can be easily connected to the entire pipeline through the first flange 9, which improves the installation convenience and sealing performance of the gate valve and the pipeline system.

[0024] Working principle: The operator rotates the handwheel 11, which drives the screw 5 to rotate, thereby moving the gate 3 upward, connecting the two connecting pipes 2, and allowing the medium in the pipeline to flow.

[0025] To close the gate valve: Turn handwheel 11 again, causing screw 5 to rotate in the opposite direction, and gate 3 to move downwards, closing connecting pipe 2 and cutting off the flow of medium in the pipeline. During the closing process of gate 3, any sand remaining in the movement path of gate 3 will be pushed into the collection chamber 6 for storage.

[0026] As the device is used for an extended period, the collection chamber 6 needs to be cleaned. When the necessary connections for the pipes, pump, and clean water source are available, remove the sealing cap 12 from the flushing pipe 8 and connect the flushing pipe 8 to the pump, valves, and clean water source via the second flange 10. Turn on the pump and inject clean water into the collection chamber 6 through the flushing pipe 8 to flush the inside of the collection chamber 6, removing accumulated mud, sand, and impurities. After flushing, turn off the pump, disconnect the connecting pipes, and reinstall the sealing cap 12.

[0027] When it is inconvenient to connect pipes, pumps, and clean water sources, keep the sealing cap 12 on the flushing pipe 8 sealed. After the device has been used for a long time, use tools to remove the fixing screws 7, remove the collection chamber 6 from the bottom of the housing 1, and empty and clean it to remove impurities. After cleaning, reinstall the collection chamber 6 back into the bottom of the housing 1 and secure it with the fixing screws 7.

[0028] Throughout the entire process, it must be ensured that both cleaning methods are performed when the gate 3 is closed and the entire pipeline is in a sealed state to ensure the safety and effectiveness of the operation.

[0029] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
