Description

Technical Field

[0001] This utility model relates to the field of valve equipment technology, and in particular to a linkage wedge mechanism for a gate. Background Technology

[0002] Gate valves are a commonly used valve structure. Due to assembly errors or excessively low operating head, the gate may not seal properly during opening and closing, and existing methods cannot solve this problem. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a linkage wedge mechanism for a gate.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a linkage wedge-type mechanism for a gate, including a guide rail, a retainer extending along the sliding direction of the gate plate, a reinforcing member fixed to the retainer, a first sliding member disposed on the gate plate, and a second sliding member disposed on the retainer. The first sliding member is connected to the second sliding member, and the first sliding member has a downward pulling effect on the second sliding member. The bottom of the reinforcing member abuts against the top of the first sliding member at the end of its upper stroke. The gate plate is provided with a plurality of first sliding members, which are arranged along the extending direction of the retainer. The second sliding members cooperate with the first sliding members one by one. The reinforcing member is located between two adjacent second sliding members. The retainer is slidably engaged with the guide rail, and the gate plate is slidably engaged with the guide rail.

[0005] As a further improvement to this design, both the first and second sliding members are wedge structures, with the inclined surface of the second sliding member facing the gate plate, and the lowest end of the inclined surface of the second sliding member being closest to the gate plate.

[0006] As a further improvement to this design, the guide rail has a U-shaped structure, the first sliding member is detachably connected to one side of the guide rail, and a reinforcing strip is provided on the other side of the guide rail, with the reinforcing strip facing the gate.

[0007] As a further improvement to this design, the guide rail is provided with a guide rail flange on one side edge of the reinforcing strip, and a sealing strip is provided between the edge of the guide rail flange and the reinforcing strip.

[0008] As a further improvement to this design, a detachable sliding shoe is also included, which is made of nylon and extends beyond the edge of the gate, i.e., the distance between the outermost edges of the oppositely positioned sliding shoes is greater than the width of the gate.

[0009] As a further improvement to this design, the second sliding element is made of molded nylon.

[0010] As a further improvement to this design, the retainer is provided with a through hole on the side facing the first slider, and the first slider is provided with a connecting part that extends into the through hole.

[0011] As a further improvement to this design, the cage is provided with a retaining flange along the length of the cage on the side facing the guide rail.

[0012] As a further improvement to this design, the two guide rails are connected at both ends of the top and bottom by connecting beams.

[0013] The beneficial effects of this utility model are: by increasing the guide area and stabilizing the gate through the retainer, this utility model effectively prevents the gate from jamming. The sliding connection between the first sliding member and the second sliding member compensates for the installation error of the gate, further avoiding the gate jamming.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The illustrative embodiments and descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0021] Example: A linkage wedge-type clamping mechanism 3 for a gate includes a guide rail, a retainer 35 extending along the sliding direction of a gate plate 1, a reinforcing member 34 fixed to the retainer 35, a first sliding member 36 disposed on the gate plate 1, and a second sliding member 33 disposed on the retainer 35. The first sliding member 36 is connected to the second sliding member 33, and the first sliding member 36 has a downward pulling effect on the second sliding member 33. The bottom of the reinforcing member 34 abuts against the top of the first sliding member 36 at the end of its upper stroke. The gate plate 1 is provided with a plurality of first sliding members 36, which are arranged along the extending direction of the retainer 35. The second sliding members 33 cooperate with the first sliding members 36 one by one. The reinforcing member 34 is located between two adjacent second sliding members 33. The retainer 35 is slidably engaged with the guide rail 30, and the gate plate 1 is slidably engaged with the guide rail 30.

[0022] The cage 35 increases the guiding area and stabilizes the gate 1, effectively preventing the gate 1 from jamming. The sliding connection between the first sliding member 36 and the second sliding member 33 compensates for installation errors of the gate 1, further preventing the gate 1 from jamming. The reinforcing member 34 facilitates the enhancement of the strength of the cage 35 and facilitates the transmission of the upward pulling force of the first sliding member 36.

[0023] Please see Figure 3 Both the first sliding member 36 and the second sliding member 33 are wedge structures. The inclined surface of the second sliding member 33 faces the gate plate 1, and the lowest point of the inclined surface of the second sliding member 33 is closest to the gate plate 1. This ensures that the gate plate 1 has a certain amount of sliding with the retainer 35 when it is tilted, and the structure is simple.

[0024] Please see Figure 4 To ensure stable contact between the retainer 35 and the guide rail 30 and to provide stability for the gate 1, the guide rail 30 adopts a U-shaped structure. To reduce maintenance costs, the first sliding member 36 is detachably connected to one side of the guide rail 30. A reinforcing strip 301 is provided on the other side of the guide rail 30 to further strengthen the guide rail 30, and the reinforcing strip 301 faces the gate 1.

[0025] Please see Figure 4 The guide rail 30 has a guide rail flange 300 on one side edge of the reinforcing strip 301, and a sealing strip 31 is provided between the edge of the guide rail flange 300 and the reinforcing strip 301. The sealing strip 31 is provided between the guide rail flange 300 and the reinforcing strip 301, which can prevent the sealing strip 31 from being excessively squeezed and deformed, thus preventing the seal from failing.

[0026] Please see Figure 3It also includes a detachable sliding shoe 32 connected to the edge of the gate plate 1 to reduce the friction between the gate plate 1 and the guide rail 30. The sliding shoe 32 is made of nylon to reduce noise. The sliding shoe 32 extends beyond the edge of the gate plate 1, that is, the distance between the outermost sliding shoes 32 that are relatively arranged is greater than the width of the gate plate 1.

[0027] Please see Figure 3 The second sliding member 33 is made of nylon molding material, which reduces noise and has a low coefficient of friction.

[0028] Please see Figure 4 To facilitate the replacement and installation of the second sliding member 33, the retainer 35 is provided with a through hole 351 on the side facing the first sliding member 36, and the first sliding member 36 is provided with a connecting part 352 extending into the through hole 351.

[0029] Please see Figure 4 The retainer 35 has a retaining flange 350 along the length of the retainer 35 on the side facing the guide rail 30, which improves the strength of the retainer 35.

[0030] Please see Figure 1 To improve the strength of the valve, the two guide rails 30 are connected by connecting beams 2 at both the top and bottom ends.

[0031] During operation, when the gate 1 moves upward, the retainer 35 moves upward through the reinforcing member 34. When the gate 1 moves downward, the retainer 35 moves through the first sliding member 36 and the second sliding member 33.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
