Description

Technical Field

[0001] This utility model relates to a gate valve, and more specifically, to a buffer gate valve. Background Technology

[0002] The gate valve's opening and closing element is a gate, and the gate's movement direction is perpendicular to the fluid flow direction. This perpendicular movement of the gate achieves the purpose of opening and closing the gate valve.

[0003] The gate of a gate valve is subject to impacts and vibrations during operation, which can cause damage and reduce its service life. Therefore, many gate valves have a buffer structure installed at the inlet. For example, a buffer gate valve, publication number CN221170808U, achieves a buffering effect by setting a ring plate and a compression spring. However, the device has the following disadvantages: it is inconvenient to replace and maintain, and it is difficult to install, which affects the normal use of the equipment. Utility Model Content

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0026] Reference Figures 1 to 5 As shown, in order to achieve the above objectives, the present invention provides the following technical solution: a buffer gate valve, including a valve body 1, a valve stem and a valve plate, wherein the valve body 1 is provided with an inlet end 2 and an outlet end 3, the valve plate is connected to the valve stem and is used to control the connection between the inlet end 2 and the outlet end 3, the inlet end 2 is provided with a flange 21, and the flange 21 is detachably connected to a buffer element 4;

[0027] The buffer component 4 includes a connecting seat 41, a mounting seat 42, a mounting component 43, and a buffer plate 44. The connecting seat 41 is detachably mounted on the flange 21, and the mounting seat 42 is detachably mounted on the connecting seat 41.

[0028] Multiple sets of mounting components 43 are provided and are arranged at equal intervals along the inner wall of the mounting base 42. The buffer plate 44 is detachably installed on the mounting component 43.

[0029] Mounting component 43 includes mounting block 431, mounting rod 432, mounting spring 433 and limiting nut 434. One end of mounting rod 432 is fixedly connected to mounting block 431, and the other end of mounting rod 432 is screwed to limiting nut 434. Mounting spring 433 is sleeved on mounting rod 432.

[0030] The buffer plate 44 is provided with multiple sets of connection holes 441 and flow holes 442. The connection holes 441 are used to cooperate with the mounting rod 432.

[0031] The design of this utility model sets the buffer 4 to be connected to the outside of the valve inlet 2, so that the buffer 4 is placed outside the valve, which is convenient for replacement and maintenance. Moreover, it does not increase the original production process during the production and processing, thus avoiding unnecessary process costs.

[0032] With the design of the buffer plate 44, when liquid flows in the valve pipeline, the liquid will come into contact with the buffer plate 44. When the buffer plate 44 is impacted, it will squeeze the installed spring 433, thereby buffering the liquid that is about to enter the water inlet 2, reducing the impact of water pressure on the valve plate and internal sealing gasket, and ensuring the service life of the equipment.

[0033] After the mounting base 42 is removed, since both ends are open, the mounting component 43 and the buffer plate 44 can be easily cleaned and inspected.

[0034] The present invention is further configured such that: the connecting seat 41 is provided with a plurality of connecting holes 441 corresponding to the flange 21 along its circumference, and the connecting holes 441 are connected to the flange 21 by connecting bolts.

[0035] The design of this structure allows for easy installation and disassembly of the flange 21.

[0036] The present invention is further configured such that: a columnar connecting part 411 is provided at one end of the connecting seat 41 away from the flange 21, and a columnar mounting part 421 is provided at one end of the mounting seat 42. The outer diameter of the mounting part 421 is adapted to the inner diameter of the connecting part 411, and a sealing ring is provided between the mounting part 421 and the connecting part 411.

[0037] The design of this structure allows the mounting part 421 to be inserted into the connecting part 411, which ensures both the stability and sealing of the connection.

[0038] The present invention is further configured such that: a threaded hole is provided through the connecting part 411, and a positioning hole is provided on the outside of the mounting part 421; the threaded hole is connected to the positioning hole by a limiting bolt. This structural design allows the connecting part 411 and the mounting part 421 to be fixed by the limiting bolt.

[0039] The present invention is further configured such that: the connecting part 411 is provided with multiple sets of guide grooves 412, and the mounting part 421 is provided with multiple sets of guide protrusions 422.

[0040] The design of this structure allows the mounting part 421 to be easily inserted into the connecting part 411, and after insertion, it facilitates the alignment of the threaded hole and the positioning hole.

[0041] The present invention is further configured such that: the buffer plate 44 is provided with an adjustment member 5 for secondary buffering, and multiple sets of adjustment members 5 are provided and are arranged at equal intervals along the circumference of the buffer plate 44.

[0042] The design of this structure provides secondary buffering for the liquid passing through the buffer plate 44, and the adjusting member 5 is preferably located on the side of the buffer plate 44 to provide secondary buffering for the liquid on the side, thereby reducing the impact effect of the liquid on the side of the gate.

[0043] This utility model is further configured such that: the adjusting component 5 includes an adjusting rod 51, an adjusting spring 52, an adjusting plate 53, and an adjusting seat 54. One end of the adjusting rod 51 is connected to the adjusting plate 53, and the other end is connected to the adjusting seat 54. The adjusting spring 52 is sleeved on the adjusting rod 51. The adjusting plate 53 is slidably connected to the adjusting rod 51 and abuts against the adjusting spring 52. The adjusting plate 53 has an arc-shaped structure. When liquid impacts the adjusting plate 53, the adjusting spring 52 is compressed, thereby achieving a buffering effect.

[0044] The adjusting seat 54 is threadedly connected to the adjusting rod 51. The threaded groove on the adjusting seat 54 is through-hole, allowing it to rotate on the adjusting rod 51.

[0045] This structure is designed to change the compression of the adjusting spring 52 by rotating the adjusting seat 54, thereby altering the thrust of the adjusting spring 52 on the adjusting plate 53. (This assumes the distance between the adjusting plate 53 and the buffer plate 44 remains unchanged.)

[0046] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
