Description

Technical Field

[0001] This utility model relates to the field of pneumatic air valve technology, specifically to a linkage-type pneumatic air valve. Background Technology

[0002] A pneumatic damper is a device for diverting or merging flow or switching the direction of flow.

[0003] A search revealed a pneumatic ventilation butterfly valve in publication number CN219911778U, comprising a valve body, an inner cavity of which is provided with a valve plate, the valve plate being disposed in the inner cavity of the valve body via a valve rod, a housing being fixedly connected to the top of the valve body, an adjusting gear, a rack and a cylinder being disposed in the inner cavity of the housing, a connecting pin being disposed at the top of the rack, an adjusting groove being provided on the left side of the housing, an adjusting block being disposed in the inner cavity of the adjusting groove, and an adjusting screw being disposed on the left side of the rack.

[0004] When using the aforementioned known technology, the connecting pin is first pulled out from the inner cavity of the rack to separate the cylinder from the rack. Then, the adjusting screw is rotated, and under the action of the adjusting screw hole, the rack is driven to move to the left, so that the rack is separated from the adjusting gear. At this time, the control lever can be rotated to drive the control gear to rotate, which in turn drives the valve rod on the adjusting gear to rotate, thereby adjusting the valve plate. The whole process is relatively cumbersome to operate and inconvenient for the operator, making the overall use of the device inconvenient.

[0005] Based on this, the present invention designs a linkage-type pneumatic air valve to solve the above problems. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0031] The present invention will be further described below with reference to the embodiments.

[0032] Example 1: Please refer to the accompanying drawings in the instruction manual. Figure 1 - Figure 6A linkage-type pneumatic air valve includes an air valve body 1; a baffle plate 2 rotatably installed inside the air valve body 1; a mounting bracket 3 fixedly installed on the outer wall of the air valve body 1; a connecting rod 4 rotatably installed on the outer wall of the air valve body 1 and fixedly connected to the baffle plate 2; and an adjustment device 5 disposed on the mounting bracket 3, the adjustment device 5 including a manual adjustment mechanism 51 and an automatic adjustment mechanism 52 disposed on the mounting bracket 3; an operating rod 53 disposed inside the connecting rod 4 and extending through its top, the operating rod 53 being rectangular and slidably connected to the connecting rod 4, the top of the operating rod 53 having a rectangular auxiliary groove; and a transmission sleeve 54 rotatably installed on the bottom wall of the mounting bracket 3 and slidably connected to the operating rod 53. The interior of 4 is rectangular, and the outer wall of the operating rod 53 is movably inserted into the interior of the transmission sleeve 54; the mounting box 55 is fixedly installed on the top of the mounting bracket 3, and the outer wall of the transmission sleeve 54 extends into the interior of the mounting box 55; the limiting plate 56 is slidably installed inside the connecting rod 4 and fixedly connected to the operating rod 53; the spring 57 is fixedly installed on the wall surface of the limiting plate 56 and the connecting rod 4, close to each other; the manual adjustment mechanism 51 includes a connecting rod 512 disposed inside the transmission sleeve 54, the connecting rod 512 is rectangular, the outer wall of the connecting rod 512 is adapted to the auxiliary groove, the connecting rod 512 is slidably connected to the top of the mounting box 55; and the auxiliary rotating wheel 511 is fixedly installed on the top wall surface of the connecting rod 512.

[0033] In practical use, when an abnormal air supply prevents the baffle 2 from opening, press the auxiliary rotating wheel 511 downwards. The connecting rod 512 will then be inserted downwards into the auxiliary groove, and the connecting rod 512 will press the operating rod 53 downwards. The limiting plate 56 will compress the spring 3 57 downwards until the connecting rod 512 can no longer move. At this time, the operating rod 53 is located outside the transmission sleeve 54. Then, hold the auxiliary rotating wheel 511 and rotate it 180 degrees. With the cooperation of the auxiliary groove and the connecting rod 512, the operating rod 53 will rotate the connecting rotating rod 4 and the baffle 2 180 degrees, thereby opening the baffle 2. After the operation is completed, release the auxiliary rotating wheel 511. The spring 3 57 returns to its original state and begins to extend. The limiting plate 56 moves the operating rod 53 upwards. Finally, the operating rod 53 is inserted back into the transmission sleeve 54. The operation is simple and convenient, and easy to use.

[0034] Example 2: Based on Example 1, please refer to the accompanying drawings in the specification. Figure 2 - Figure 8The automatic adjustment mechanism 52 includes a mounting box 522 fixedly mounted on the top of the mounting bracket 3; an air supply mechanism 521 disposed on the mounting box 522; a sealing piston 523 slidably connected inside the mounting box 522; a movable push rod 524 fixedly mounted on the right side wall of the sealing piston 523, the outer wall of the movable push rod 524 movably passing through the right side wall of the mounting box 522 and the left side wall of the mounting box 55, and the movable push rod 524 slidably connected to both the mounting box 522 and the mounting box 55; and a spring 525 fixedly mounted on the sealing piston 523 and the mounting box 522 near the wall, the outer wall of the movable push rod 524 movably passing through the interior of the spring 525, and the springs 525 slidably connected.

[0035] The automatic adjustment mechanism 52 also includes a rack 526 that is slidably installed inside the mounting box 55, the rack 526 and the movable push rod 524 being fixedly connected; and a gear 527 that is fixedly installed on the outer wall of the transmission sleeve 54, the gear 527 and the rack 526 being meshed together.

[0036] The gas supply mechanism 521 includes a connecting pipe 5211 sealed to the left side wall of the mounting box 522; an auxiliary collar 5212 threaded to the outer wall of the connecting pipe 5211; a regulating pipe 5214 fixedly installed on the left side wall of the auxiliary collar 5212; a regulating pipe 5213 fixedly installed on the left side wall of the connecting pipe 5211, the regulating pipe 5213 being tapered, with uniformly distributed air inlets on its outer wall, the left end of the regulating pipe 5213 being located inside the regulating pipe 5214, the inner wall of the regulating pipe 5214 being tapered, the taper of the regulating pipe 5214 being the same as the taper of the regulating pipe 5213; and a gas pipe connector 5215 rotatably installed on the left side wall of the regulating pipe 5214.

[0037] The manual adjustment mechanism 51 also includes a limiting sleeve 513 fixedly installed on the top wall of the mounting box 2 55, the outer circular wall of the auxiliary rotating wheel 511 and the limiting sleeve 513 are slidably connected; and a spring 1 514 fixedly installed on the top wall of the mounting box 2 55, the upper side wall of the spring 1 514 and the lower side wall of the auxiliary rotating wheel 511 are in contact with each other, the outer wall of the connecting rod 512 moves through the interior of the spring 1 514, and the connecting rod 512 and the spring 1 514 are slidably connected.

[0038] In practical use, an external air pipe is connected through the air pipe connector 5215. Gas enters the interior of the regulating pipe two 5214 from the interior of the air pipe connector 5215, then enters the interior of the regulating pipe one 5213 through the air inlet, and finally enters the interior of the mounting box one 522 through the connecting pipe 5211. As the gas increases, the internal pressure of the mounting box one 522 increases. The gas pushes the sealing piston 523, causing the moving push rod 524 to move to the right. The spring two 525 is compressed, the rack 526 moves to the right, and the gear 527 rotates the transmission sleeve 54. Under the limit of the transmission sleeve 54, the operating rod 53 rotates the connecting rotating rod 4, thereby realizing the automatic rotation of the wind deflector 2. By rotating the auxiliary collar 5212, the regulating pipe two 5214 can be moved. When the regulating pipe two 5214 moves to the right, the inner wall of the regulating pipe two 5214 approaches the regulating pipe one. 5213 reduces the gap between the inner wall of regulating pipe 2 5214 and the outer wall of regulating pipe 1 5213, thus reducing the amount of gas entering regulating pipe 2 5214. This changes the amount of air entering the mounting box 1 522 under the same pressure, allowing adjustment of the opening of the baffle 2. It can be used according to specific circumstances, increasing functionality. In addition, when the auxiliary wheel 511 is pressed down, the spring 1 514 is compressed. When the auxiliary wheel 511 is released, the spring 1 514 extends, causing the auxiliary wheel 511 to move upward with the connecting rod 512. The auxiliary wheel 511 returns to its original position, and the connecting rod 512 separates from the auxiliary groove. During automatic control, the connecting rod 512 will not rotate with the operating lever 53, so the auxiliary wheel 511 is stationary during automatic control, preventing rotation that could cause injury and improving safety.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
