Description

Technical Field

[0001] This utility model relates to the field of gate valve technology, and in particular to a wear-resistant gate valve. Background Technology

[0002] A gate valve is a valve that uses a gate or wedge-shaped disc that moves perpendicular to the fluid to open or close the flow of fluid in a pipeline. The gate is the opening and closing element of a gate valve, and its movement is perpendicular to the direction of fluid flow. Gate valves can only be fully open or fully closed; they cannot be used for regulation or throttling.

[0003] In the long-term use of traditional gate valves, the current state of the valve is adjusted by the up and down movement of the valve plate. Some water flows contain a small amount of sand and gravel, and a small amount of sand and gravel will accumulate inside the gate valve. When the valve plate comes into contact with the sand and gravel inside the gate valve, the sand and gravel will cause abrasion on the surface of the valve plate. This continuous wear will inevitably reduce the effective service life of the gate valve. Utility Model Content

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Therefore, the purpose of this utility model is to provide a wear-resistant gate valve, which solves the problem that "in the long-term use of traditional gate valves, the current state of the valve is adjusted by the up and down movement of the valve plate. Some water flow contains a small amount of sand and gravel, and a small amount of sand and gravel will accumulate inside the gate valve. When the valve plate comes into contact with the sand and gravel inside the gate valve, the sand and gravel will cause abrasion on the surface of the valve plate.

[0030] Reference Figure 1-6 This utility model provides a wear-resistant gate valve, comprising:

[0031] The main unit 100 includes a valve body 101. A fixing block 102 is fixedly connected to the upper end face of the valve body 101. Two connecting pipes 103 are symmetrically fixedly connected to the valve body 101. A square block 107 is fixedly sleeved on the left end connecting pipe 103. The fixing block 102 has a cavity, and the square block 107 has a connecting cavity. Two connecting ports are symmetrically opened on the upper end face of the square block 107.

[0032] The working component 200 includes a connecting block 201, an auxiliary component 208, and a lifting component 209. The connecting block 201 is mounted on a square block 107. Two vertical blocks 210 are symmetrically fixedly connected to the connecting block 201. Both vertical blocks 210 pass through the connecting port and are connected to a vertical plate 202. The vertical plate 202 has a circular opening, in which a filter circular plate 203 is fixedly installed. Vertical plates 204 are symmetrically fixedly connected to the inner wall of the connecting cavity. The two vertical plates 204 abut against the filter circular plate 203. Two mounting plates are fixedly connected to the upper end face of the square block 107. A threaded rod 205 is rotatably connected to the left mounting plate. A threaded sleeve 206 is threaded onto the threaded rod 205. A first moving rod 207 is fixedly connected to the threaded sleeve 206. Two vertical slots are symmetrically opened on the connecting block 201. The end of the first moving rod 207 facing away from the threaded sleeve 206 is located in one of the vertical slots. The auxiliary component 208 is installed on the right end mounting plate, the lifting component 209 is installed in the connecting cavity, the vertical plate 202 has an installation cavity, and the lower end of each vertical block 210 passes through the upper end of the vertical plate 202 and is installed in the installation cavity. Each vertical block 210 is fixedly connected to a connecting clip 211. The filter disc 203 can filter sand and other impurities in the flowing water, thereby avoiding wear and damage to the gate valve caused by sand and other impurities and improving the sealing performance of the gate valve. Rotating the threaded rod 205, the threaded rod 205 drives the connecting block 201 to move upward through the threaded sleeve 206 and the first moving rod 207, thereby facilitating the lifting of the vertical plate 202 and the filter disc 203. The vertical plate 202 and the filter disc 203 are moved out of the square block 107, which facilitates the cleaning of impurities filtered on the filter disc 203 and ensures the filtration effect of the filter disc 203 on sand and other impurities in the water flow.

[0033] The auxiliary component 208 includes a vertical rod 208a, which is fixedly connected to the right end mounting plate. A sliding sleeve 208b is slidably sleeved on the vertical rod 208a. A second moving rod 208c is fixedly connected to the sliding sleeve 208b. The end of the second moving rod 208c away from the sliding sleeve 208b is set in the vertical groove. A square plate 208d is fixedly connected to the upper end of the vertical rod 208a. When the connecting block 201 moves up and down, the sliding sleeve 208b is driven to move up and down on the vertical rod 208a through the second moving rod 208c.

[0034] Furthermore, the lifting assembly 209 includes a connecting shaft 209a and a sealing valve plate 209d. The connecting shaft 209a is rotatably inserted through the upper end face of the fixed block 102. A handle 209b is fixedly connected to the connecting shaft 209a, and a screw 209c is fixedly connected to the lower end of the handle 209b. A through-hole is opened on the upper end face of the valve body 101, through which the sealing valve plate 209d passes. The sealing valve plate 209d has a threaded groove, and the screw 209c is disposed in the threaded groove. Two connecting plates 209e are symmetrically fixedly connected to the inner wall of the valve body 101. Each connecting plate 209e is provided with a sliding groove. The sealing valve plate 209d is set in the two sliding grooves. When the handle 209b is rotated, the handle 209b drives the screw 209c to rotate through the connecting shaft 209a, which in turn drives the sealing valve plate 209d to move up and down, adjusting the opening and closing of the gate valve. The filter disc 203 can filter sand and other impurities in the flowing water.

[0035] Furthermore, the left end of the left connecting pipe 103 is provided with an inlet pipe 104, and the right end of the right connecting pipe 103 is provided with an outlet pipe 105. Both connecting pipes 103, the inlet pipe 104, and the outlet pipe 105 are provided with a connecting flange 106. The inlet pipe 104 and the outlet pipe 105 can be installed on the connecting pipe 103 through the connecting flange 106.

[0036] During use, rotating the handle 209b causes the screw 209c to rotate via the connecting shaft 209a, which in turn moves the sealing valve plate 209d up and down, adjusting the opening and closing of the gate valve. The filter disc 203 filters out impurities such as sand and gravel in the flowing water, preventing them from contacting the sealing valve plate 209d and causing wear and damage, thus improving the sealing performance of the gate valve. Rotating the threaded rod 205 causes the connecting block 201 to move upward via the threaded sleeve 206 and the first moving rod 207, which in turn moves the vertical block 210 and the connecting clamp block 211 upward. The vertical plate 202 and the filter disc 203 can be lifted by the connecting block 201, the vertical block 210, and the connecting clamp block 211, removing the square block 107 for easy cleaning of the impurities filtered out by the filter disc 203, ensuring the filtering effect of the filter disc 203 on impurities such as sand and gravel in the water flow.

[0037] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
