Description

Technical Field

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

[0002] Gate valves, also known as shut-off valves, are among the most widely used valves. Their popularity stems from the low friction between the sealing surfaces during opening and closing, resulting in durability. They also have a small opening height, are easy to manufacture and maintain, and are suitable for both low and medium pressures as well as high pressures. However, existing gate valves may not effectively intercept impurities in the fluid, allowing these impurities to enter downstream equipment or systems, causing blockages or damage. Furthermore, existing gate valves may have insufficient sealing performance, leading to fluid leakage even when the valve is closed. This not only wastes resources but may also damage the environment and equipment. For example, a Chinese patent discloses "a novel gate valve" with application number "202123142561.X". This valve uses bolts and threaded grooves to fix the cover plate and valve body together with bolts and threaded holes. Because the valve body is filled with water for a long time, the inner wall of the valve body needs to be inspected regularly for cracks. By turning the bolts and removing them from the threaded grooves, the cover plate can be separated from the valve body. This achieves the effect of simple installation and disassembly and easy inspection of the inner wall of the valve body. However, the sealing structure and sealing effect of this valve are relatively weak, and there is still a risk of fluid leakage, which affects the reliable operation of the gate valve. Utility Model Content

[0003] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a novel shut-off valve. By manually rotating the rotating handle, the upper and lower rotating plates are driven to rotate via the rotating rod, precisely controlling the alignment or misalignment of the upper and lower delivery pipes, thus achieving flexible opening and closing of the fluid channel. At the same time, the upper and lower sealing gaskets are tightly fitted with the rotating plate, and the sealing ring enhances the sealing between the rotating rod, the upper and lower delivery pipes and the housing, effectively preventing fluid leakage and ensuring reliable operation of the shut-off valve. The upper and lower delivery pipes are connected to the filter box via a threaded connector. The packing inside the filter box can intercept fluid impurities, achieving efficient filtration. Meanwhile, a protective cover with a locking handle is rotatably connected to the front surface of the housing, with the filter box located behind it. When maintenance or replacement of the filter box is required, the locking handle can be opened and the protective cover rotated to expose the filter box for operation, making maintenance convenient, extending the service life of the shut-off valve and ensuring fluid purity.

[0004] This utility model also provides a novel shut-off valve, comprising: a housing; an upper sealing gasket fixedly connected to the inner side wall of the housing; an upper rotating plate rotatably connected to the inside of the housing; an upper conveying pipe embedded inside the upper rotating plate; a rotating rod fixedly connected to the upper surface of the upper rotating plate; a rotating handle fixedly connected to the upper end of the rotating rod; a lower sealing gasket fixedly connected to the inner side wall of the housing; a lower rotating plate rotatably connected to the inside of the housing; a lower conveying pipe embedded inside the lower rotating plate; a filter box threadedly connected to the lower end of the upper conveying pipe and the upper end of the lower conveying pipe via a connector; packing material disposed inside the filter box; a protective cover rotatably connected to the front surface of the housing via a hinge; an input pipe fixedly connected to the right surface of the housing; and an output pipe fixedly connected to the left surface of the housing.

[0011] According to the present invention, a novel shut-off valve is provided, wherein the upper conveying pipe, the filter box, and the lower conveying pipe are interconnected, and the above device is beneficial to achieving the filtration effect.

[0012] Compared with existing technologies, this new type of gate valve allows for precise control of the alignment or misalignment of the upper and lower delivery pipes by manually rotating the handle, which in turn drives the upper and lower rotating plates to rotate via a rotating rod. This enables flexible opening and closing of the fluid passage. Simultaneously, the upper and lower sealing gaskets fit tightly against the rotating plates, and the sealing ring further enhances the sealing between the rotating rod, the upper and lower delivery pipes, and the housing, effectively preventing fluid leakage and ensuring reliable operation of the gate valve.

[0020] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4This utility model discloses a novel shut-off valve, comprising: a housing 1, an upper sealing gasket 8 fixedly connected to the inner side wall of the housing 1, an upper rotating plate 13 rotatably connected inside the housing 1, the upper rotating plate 13 being located at the center of the upper sealing gasket 8, an upper conveying pipe 9 embedded inside the upper rotating plate 13, a rotating rod 6 fixedly connected to the upper surface of the upper rotating plate 13, a rotating handle 3 fixedly connected to the upper end of the rotating rod 6, the rotating rod 6 penetrating the upper top wall of the housing 1, the rotating handle 3 being located above the housing 1, a lower sealing gasket 17 fixedly connected to the inner side wall of the housing 1, a lower rotating plate 16 rotatably connected inside the housing 1, the lower rotating plate 16 being located at the center of the lower sealing gasket 17, a lower conveying pipe 15 embedded inside the lower rotating plate 16, and a sealing ring 7 fixedly connected inside the housing 1, the sealing ring 7 being located on the side surfaces of the rotating rod 6, the upper conveying pipe 9, and the lower conveying pipe 15.

[0022] Specifically, the housing 1 serves as the main support structure of the entire shut-off valve, providing space for the installation and fixing of various internal components. It houses components such as the upper rotating plate 13, lower rotating plate 16, upper sealing gasket 8, lower sealing gasket 17, and sealing ring 7. Through its connection with the input pipe 2 and output pipe 5, it forms the overall path for fluid flow. Manually rotating the rotating handle 3 transmits rotational force to the rotating rod 6, thereby controlling the rotation of the upper rotating plate 13 and lower rotating plate 16, thus enabling the shut-off valve to flow. The upper delivery pipe 9 and lower delivery pipe 15 are respectively embedded inside the upper rotating plate 13 and lower rotating plate 16. When the rotating plate 16 rotates to the position where the upper conveying pipe 9 and the lower conveying pipe 15 are aligned, the fluid can flow from the input pipe 2 through the connection port 14, the upper conveying pipe 9, the filter box 11, the lower conveying pipe 15 and another connection port 14 to the output pipe 5; when the upper rotating plate 13 and the lower rotating plate 16 rotate to the position where the upper conveying pipe 9 and the lower conveying pipe 15 are misaligned, the fluid passage is cut off and the fluid cannot pass through the shut-off valve. During this process, the upper sealing gasket 8 and the lower sealing gasket 17 will fit tightly against the rotating plate. By utilizing the elasticity and surface characteristics of the sealing gasket, the fluid is prevented from passing through the gap between the rotating plate and the inner wall of the housing 1, thus achieving a sealing effect.

[0023] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4The upper conveying pipe 9 and the lower conveying pipe 15 are connected to the filter box 11 by a threaded connector 10. The upper conveying pipe 9 is located above the filter box 11, and the lower conveying pipe 15 is located below the filter box 11. The upper conveying pipe 9, the filter box 11, and the lower conveying pipe 15 are interconnected. The filter box 11 is filled with packing material 12. The front surface of the housing 1 is connected to the protective cover 4 by a hinge. The front surface of the protective cover 4 is provided with a locking handle. The filter box 11 is located directly behind the protective cover 4. The right surface of the housing 1 is fixedly connected to the input pipe 2, and the left surface of the housing 1 is fixedly connected to the output pipe 5. The upper sealing gasket 8 and the lower sealing gasket 17 are provided with a connection port 14. The input pipe 2 and the output pipe 5 are connected to the housing 1 and the connection port 14.

[0024] Specifically, the lower end of the upper delivery pipe 9 and the upper end of the lower delivery pipe 15 are threadedly connected to a filter box 11 via a connector 10. When the fluid passes through the shut-off valve, it will pass through the filter box 11. The packing 12 inside the filter box 11 can intercept impurities in the fluid and play a filtering role. The protective cover 4 is rotatably connected to the front surface of the housing 1 via a hinge and is provided with a locking handle, which can lock the protective cover 4 in the closed state. When it is necessary to maintain or replace the filter box 11, the locking handle is opened and the protective cover 4 is rotated to expose the filter box 11 for operation. During the flow of fluid in the shut-off valve, the connection port 14 is located inside the upper sealing gasket 8 and the lower sealing gasket 17 and is connected to the inlet pipe 2, the outlet pipe 5 and the fluid channel inside the housing 1. When the shut-off valve is open, the fluid can flow through the connection port 14 between the inlet pipe 2, the upper delivery pipe 9, the filter box 11, the lower delivery pipe 15 and the outlet pipe 5.

[0025] Working principle: The housing 1 serves as the main supporting structure, housing components such as the upper rotating plate 13, lower rotating plate 16, upper sealing gasket 8, lower sealing gasket 17, and sealing ring 7. It is connected to the input pipe 2 and the output pipe 5 to form a fluid flow path. By manually rotating the rotating handle 3 located above the housing 1, the rotational force is transmitted to the upper rotating plate 13 through the rotating rod 6, which in turn drives the upper rotating plate 13 and the lower rotating plate 16 to rotate. When the upper rotating plate 13 and the lower rotating plate 16 rotate to align the upper delivery pipe 9 and the lower delivery pipe 15 embedded inside, the fluid flows from the input pipe 2 through the connection port 14, the upper delivery pipe 9, the filter box 11 (with packing 12 inside the filter box 11 to intercept fluid impurities) threaded between the lower end of the upper delivery pipe 9 and the upper end of the lower delivery pipe 15 through the connector 10, to the output pipe 5. When the two rotate to make the upper delivery pipe 9 and the lower delivery pipe 15 misaligned, the fluid channel is cut off, and the fluid cannot pass through. During this process, the upper sealing gasket 8 and the lower sealing gasket 17 are tightly fitted to the rotating plate, using their own elasticity and surface properties to prevent fluid from passing through the gap between the rotating plate and the inner wall of the housing 1, thus achieving a seal. The sealing ring 7 enhances the sealing performance between the rotating rod 6, the upper delivery pipe 9, the lower delivery pipe 15, and the housing 1. In addition, a protective cover 4 with a locking handle is rotatably connected to the front surface of the housing 1 via a hinge, with the filter box 11 located directly behind it. When maintenance or replacement of the filter box 11 is required, the locking handle can be opened and the protective cover 4 can be rotated to expose the filter box 11 for operation.

[0026] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
