Description
Technical Field
[0001] This utility model relates to the field of bypass valve processing technology, and in particular to a tightening mechanism suitable for a double-sided knob of a bypass valve. Background Technology
[0002] A bypass pipe is installed on the bypass pipe section of the inlet valve to balance the water pressure before and after the inlet valve. Valves such as pressure reducing valves, control valves and steam traps are usually equipped with bypass pipes. Valves installed on bypass pipes are called bypass valves. Bypass valves refer to valves installed on bypass pipes. During the production process of bypass valves, it is necessary to tighten both sides of the bypass valve through a tightening device.
[0003] In the process of realizing this utility model, the inventors discovered that the technology has at least the following problems: when the existing tightening device clamps the two sides of the bypass valve, it only uses a simple clamping tool to clamp the bypass valve, and the bypass valve will swing out and shake due to the high speed of the motor rotation.
[0004] Secondly, the existing tightening device lacks a protective structure for the bypass valve, which is prone to damage when tightened.
[0005] Therefore, a tightening mechanism suitable for dual-sided knobs of bypass valves is now proposed. Utility Model Content

[0033] The following description, in conjunction with the embodiments of this utility model, includes appendices. Figure 1-4 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0034] Please refer to Figure 1-4A tightening mechanism for a bypass valve dual-sided knob includes a main body 1. The four corners of the bottom of the main body 1 are provided with support feet 101. One side of each support foot 101 is provided with a caster wheel 102. The front edge of the main body 1 is provided with a placement box 103. The upper edge of the main body 1 is provided with a control console 104. The rear edge of the main body 1 is provided with a control panel 105. The upper surface of the main body 1 is symmetrically provided with protective boxes 2 on the left and right sides. The protective boxes 2 contain motors. The upper surface of the main body 1 is provided with a mounting plate 3 between the two protective boxes 2. The upper surface of the main body 1 is provided with a column 4 behind the mounting plate 3.
[0035] The motor output end inside the protective box 2 is provided with a clamping plate 201. The clamping plate 201 is circular in shape. The middle part of the clamping plate 201 is a through structure. A clamping ring 202 is provided at the through part of the middle part of the clamping plate 201. Both the clamping plate 201 and the clamping ring 202 are elastic structures.
[0036] The clamping ring 202 is surrounded by a clamping block 203, which is trapezoidal in shape. The clamping plate 201 has an adjustment port 204 on one side, and an electric telescopic rod 205 is provided at the adjustment port 204.
[0037] The bypass valve is placed between two clamping plates 201. The two clamping plates 201 clamp the left and right sides of the bypass valve. The motor is started to drive the clamping plates 201 to rotate, thereby achieving the tightening of the bypass valve.
[0038] Meanwhile, when clamping bypass valves of different diameters, the electric telescopic rod 205 is controlled to open the adjustment port 204 of the clamping ring 202, and then clamps the bypass valve, thereby achieving the clamping of bypass valves of different diameters and increasing its applicability.
[0039] Reference Figure 2 The upper surface of the mounting plate 3 is provided with a card holder 301. The card holder 301 is irregularly concave in shape. Placement slots 302 are opened on the front and rear top of the card holder 301. The placement slots 302 are semi-circular in shape.
[0040] Card slots 303 are provided on both sides of the interior depth of the card holder 301, and the card slots 303 are circular in shape.
[0041] The left and right sides of the placement groove 302 are provided with protective grooves 304, and the edges of the protective grooves 304 are provided with rubber gaskets.
[0042] The bypass valve is placed inside the holder 301, and the head of the bypass valve is placed inside the placement groove 302. The semi-circular placement groove 302 can effectively fit the head of the bypass valve. At the same time, the protective groove 304 inside the placement groove 302 can effectively protect the bypass valve. Furthermore, the bottom of the bypass valve is embedded in the holder 303, thereby achieving a further protective effect on the bypass valve.
[0043] Reference Figure 3 The top of the column 4 is equipped with a cylinder 401, and the output end of the cylinder 401 is equipped with a pressure plate 402, which is located directly above the card holder 301.
[0044] The pressure plate 402 is generally arranged in an inverted T-shape. A pressure groove 403 is opened at the bottom of the pressure plate 402. The pressure groove 403 is semi-circular. An adjustment block 404 is provided on the inner side of the pressure groove 403. The adjustment block 404 is a movable and telescopic structure.
[0045] When the bypass valve is placed inside the seat 301, the control cylinder 401 drives the pressure plate 402 to press down, thereby making the pressure plate 402 contact the top of the outer surface of the bypass valve, and pressing the pressure groove 403 into the top of the bypass valve, thereby achieving the effect of limiting and fixing the bypass valve, preventing it from shifting or loosening when tightening the bypass valve. At the same time, the adjusting block 404 can limit the bypass valves of different diameters. By extending and retracting the adjusting block 404 inside the pressure plate 402, the limiting effect of bypass valves of different diameters can be achieved.
[0046] The implementation principle of this utility model is as follows: First, the bypass valve is placed inside the card holder 301, and the bypass valve is limited by the card holder 301. At the same time, the control motor drives the two clamping plates 201 to clamp the left and right sides of the bypass valve. The control cylinder 401 drives the pressure plate 402 to press down, thereby protecting the bypass valve. The motor is started to drive the clamping plates 201 to rotate, thereby tightening the bypass valve.
[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
