Description

Technical Field

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

[0002] Knife gate valves, also known as knife gate valves, slurry valves, or mud valves, use a gate as their opening and closing element. The gate moves in a direction perpendicular to the fluid direction. The medium is cut off by the blade-shaped gate that can cut through fibrous materials. If a higher level of media sealing is required, an O-ring seal valve seat can be used to achieve bidirectional high-pressure sealing.

[0003] However, when a knife gate valve is installed outdoors for long-term use, external factors such as strong winds or ground vibrations caused by vehicles can easily cause the pipeline to shake, causing the knife gate valve to shake along with the pipeline. Prolonged shaking can affect the sealing of the connection between the knife gate valve and the pipeline, leading to leakage. Therefore, mounting brackets are needed to ensure the stability of the knife gate valve installation. Utility Model Content

[0004] This invention provides a support for a knife gate valve to solve the problems mentioned in the background art.

[0005] To address the aforementioned issues, this utility model provides a support for a knife gate valve, comprising a mounting plate. A support frame is fixedly mounted at each of the top two ends of the mounting plate. Two slide rails are symmetrically arranged between the two support frames in the mounting plate. Two clamping frames are slidably connected between the two support frames in the mounting plate. A telescopic support leg is mounted at each of the four corners of the bottom of the mounting plate. A sliding frame, slidably connected to the slide rails, is mounted at the bottom of the clamping frame. Several threaded holes are symmetrically and equidistantly arranged on both sides of the slide rails at the bottom of the mounting plate. A positioning hole matching the threaded hole is provided at each end of the sliding frame. The sliding frame is positioned in the mounting plate by bolts engaging the positioning holes and threaded holes.

[0006] Preferably, the top of the support frame is fixed with a semi-circular fixed hoop, and the upper part of the fixed hoop is connected to a semi-circular movable hoop by bolts. The fixed hoop and the movable hoop form a ring, and its inner diameter matches the outer diameter of the pipe.

[0007] Preferably, the top of the clamping frame is semi-circular, and the inner side of the clamping frame abuts against the outer surface of the knife gate valve, and a rubber pad is provided in the inner side of the clamping frame that abuts against the outer surface of the knife gate valve.

[0008] Preferably, the telescopic support leg is composed of a support column and a telescopic column. The top end of the telescopic column is fixedly connected to the mounting plate, and the bottom end of the telescopic column is slidably inserted into the support column. The telescopic column has several positioning through holes, and the top of the support column has a connecting through hole that matches the positioning through hole. The telescopic column and the support column are fixedly connected by bolts through the connecting through hole and the positioning through hole.

[0009] The beneficial effects of adopting the above technical solutions are:

[0010] By setting up the support frame, the pipes connected to both ends of the knife gate valve can be fixed. The clamping frame can clamp the knife gate valve onto the mounting plate. Then, by using bolts in conjunction with the positioning holes and threaded holes, the clamping frame is fixed onto the mounting plate, thereby making the connection between the knife gate valve and the pipe more stable and in a supported state, preventing it from being suspended after installation, and thus avoiding leakage caused by shaking due to external forces.

Detailed Implementation

[0014] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0015] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, a movable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] like Figure 1-2 In this embodiment, a support for a knife gate valve includes a mounting plate 1. A support frame 2 is fixedly mounted at each of the top two ends of the mounting plate 1. Two slide rails 11 are symmetrically arranged between the two support frames 2 in the mounting plate 1. Two clamping frames 3 are slidably connected between the two support frames 2 in the mounting plate 1. A telescopic support leg 4 is installed at each of the four corners of the bottom of the mounting plate 1. A sliding frame 31, slidably connected to the slide rails 11, is installed at the bottom of the clamping frame 3. Several threaded holes 12 are symmetrically and equidistantly arranged on both sides of the slide rails 11 at the bottom of the mounting plate 1. A positioning hole 32 matching the threaded hole 12 is opened at each end of the sliding frame 31. The sliding frame 31 is positioned in the mounting plate 1 by bolts engaging the positioning hole 32 and the threaded hole 12.

[0018] With the above technical solution, the knife gate valve is installed on the mounting plate 1 between two clamping frames 3. The clamping frames 3, in conjunction with the sliding frame 31 and the slide rail 11, slide from both sides of the knife gate valve and abut against the sides of the knife gate valve to clamp it. Then, bolts are used to fit the positioning holes 32 in the sliding frame 31 and the threaded holes 12 in the mounting plate 1, thereby firmly clamping the knife gate valve on the mounting plate 1. Then, the pipes connected to both sides of the valve body are fixed by the support frame 2, thereby making the connection between the knife gate valve and the pipes more stable. The setting of the telescopic support leg 4 provides support to the mounting plate 1, thereby preventing the knife gate valve and the pipes from being suspended after installation, further improving the stability after installation, and preventing shaking caused by external forces, thus preventing leakage. The setting of the telescopic support leg 4 makes the height of the mounting plate 1 adjustable, thereby improving applicability.

[0019] Preferably, the top of the support frame 2 is fixed with a semi-circular fixed hoop 21, and the upper part of the fixed hoop 21 is connected to a semi-circular movable hoop 22 by bolts. The fixed hoop 21 and the movable hoop 22 form a ring, and its inner diameter matches the outer diameter of the pipe.

[0020] Through the above technical solution, the movable clamp 22 in the support frame 2 cooperates with the fixed clamp 21 to facilitate the mounting of the pipe on the mounting plate 1 and ensure the stability after fixing.

[0021] Preferably, the top of the clamping frame 3 is semi-circular, and the inner side of the clamping frame 3 abuts against the outer surface of the knife gate valve. A rubber pad 31 is provided in the inner side of the clamping frame 3 that abuts against the outer surface of the knife gate valve.

[0022] Through the above technical solution, the semi-circular top of the clamping frame 3 allows the clamping frame 3 to clamp the valve body relatively stably without hindering the connection between the gate valve and the pipeline. At the same time, the rubber pad can prevent the clamping frame 3 from rigidly colliding with the valve body surface of the gate valve.

[0023] Preferably, the telescopic support leg 4 is composed of a support column 41 and a telescopic column 42. The top end of the telescopic column 41 is fixedly connected to the mounting plate 1, and the bottom end of the telescopic column 42 is slidably inserted into the support column 41. The telescopic column 42 has several positioning through holes 43. The top of the support column 41 has a connecting through hole 44 that matches the positioning through hole 43. The telescopic column 42 and the support column 41 are fixedly connected by bolts through the connecting through hole 44 and the positioning through hole 43.

[0024] Through the above technical solution, the telescopic column 42 is slidably connected to the inside of the support column 41, so that the length of the telescopic support leg 4 is adjustable, and thus the height of the mounting plate 1 is adjustable, improving applicability. By using bolts to connect the through hole 44 in the support column 42 and the positioning through hole 43 in the telescopic column 41, the adjusted telescopic column 42 and the support column 41 can be positioned to ensure the stability after length adjustment.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate this utility model and are not intended to limit the technical solutions described in this utility model. Therefore, although this specification has described this utility model in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model, and all technical solutions and improvements that do not depart from the spirit and scope of this utility model should be covered within the scope of the claims of this utility model; technologies not described in detail in this utility model are implemented using existing technologies.
