Description

Technical Field

[0001] This utility model relates to the field of air pressure adjustment technology for intake valves, and in particular to an air pressure adjustment mechanism for intake valves. Background Technology

[0002] In piping systems, air intake valves are primarily used to control the entry of air or gas to ensure the normal operation of the system. For example, in water supply piping systems, air intake valves can be used to control the entry of air to prevent water hammer; in gas piping systems, air intake valves can be used to control the entry of gas to regulate the combustion process.

[0003] During the operation of air intake valves, it is often necessary to adjust their air pressure. For example, in systems such as water supply pipelines, if the air pressure of the air intake valve is too low, it may lead to cavitation, affecting the normal operation of the system. Adjusting the air pressure can prevent cavitation. In systems such as gas pipelines, adjusting the air pressure of the air intake valve can prevent overpressure or underpressure, protecting the safe operation of the system. In short, adjusting the air pressure of the air intake valve is an important measure to ensure the normal operation of the system, improve performance, reduce failures, and extend equipment life.

[0004] Currently, intake valve pressure adjustment typically relies on manual operation using tools like wrenches to rotate the pressure adjusting nut. However, in certain situations, manually rotating the pressure adjusting nut becomes difficult or impossible. For example, if the nut has been unused for a long time or exposed to a humid environment, it may corrode, causing the nut and bolt to stick together and making manual rotation difficult. Alternatively, the nut may have been over-tightened, exceeding the torque range of a manual wrench, making manual rotation impossible. Therefore, there is an urgent need for an intake valve pressure adjustment mechanism to solve these technical problems. Utility Model Content

[0005] This utility model discloses a pneumatic pressure adjustment mechanism for an intake valve. By incorporating a drive adjustment mechanism, when the pneumatic pressure adjustment nut of the intake valve cannot be turned manually due to special circumstances, the device can be mounted on top of the intake valve and pipeline. A socket wrench is then engaged with the pneumatic pressure adjustment nut, and the device is clamped and fixed to the pipeline by a clamping mechanism. Since the height of the clamping mechanism can be adjusted using a telescopic guide rod, it is applicable to various clamping and fixing situations. After the device is clamped and fixed, a reduction motor is activated. The reduction motor, in conjunction with two gears, drives a rotating shaft to rotate with a large torque. This rotating shaft, in conjunction with a mounting base and a mounting post, drives the socket wrench to rotate with a large torque, thereby rotating the pneumatic pressure adjustment nut and achieving the purpose of adjusting the pneumatic pressure of the intake valve. In summary, this invention solves the problems in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] The present invention provides an air pressure adjustment mechanism for an air intake valve, including a mounting base, wherein two sets of telescopic guide rods are fixedly connected to the bottom of the mounting base, and a connecting base is fixedly connected to the bottom of each set of telescopic guide rods.

[0008] The drive adjustment mechanism includes a geared motor, a rotating shaft, a mounting base, a mounting post, and a locking bolt.

Gears are fixedly connected to both the output end of the geared motor and the outside of the rotating shaft. The two gears mesh with each other. The top of the mounting base is fixedly connected to the bottom end of the rotating shaft. The bottom of the mounting base has a mounting groove extending into it. The mounting groove is rectangular. The mounting post matches and engages with the mounting groove. The mounting base and the mounting post are locked together by a locking bolt. A socket wrench is fixedly connected to the bottom of the mounting post.

[0009] A clamping and fixing mechanism is located at the bottom of the two connecting seats.

[0010] Furthermore, two handles are fixedly connected to the top of the mounting base, with the two handles located near the front and rear sides of the mounting base, respectively.

[0011] Furthermore, the clamping post and the socket wrench are fixedly connected by welding, and the clamping seat and the rotating shaft are also fixedly connected by welding.

[0012] Furthermore, the clamping and fixing mechanism includes a fixing plate, clamping knobs, and clamping blocks. The clamping and fixing mechanism is provided in four sets. The four fixing plates are arranged in pairs, and the two sets of fixing plates are respectively fixedly installed on the bottom of two connecting seats. The four clamping knobs are arranged in pairs, and one end of the two clamping knobs in the same set passes through the two fixing plates by screwing. One side of the four clamping blocks is rotatably connected to the four clamping knobs by rotating connectors. V-shaped grooves are opened on the opposite sides of the two clamping blocks in the same set.

[0013] Furthermore, the bottom of the connecting seat is provided with two sliding grooves, and the top of the clamping block is slidably connected to the two sliding grooves through multiple sliding connectors.

[0014] Furthermore, anti-slip pads are attached and fixed to the inner wall of the V-shaped groove of the clamping block, and the anti-slip pads are made of rubber material.

[0015] Furthermore, the fixing plate is made of aluminum alloy, and the fixing plate and the connecting seat are fixedly connected by welding.

This solution is highly practical.

[0018] 2. This technical solution incorporates a clamping and fixing mechanism, which allows the device to be clamped and fixed to the pipe near the air inlet valve during operation. This facilitates the subsequent rotation of the air pressure adjusting nut and is applicable to various pipe sizes, thereby further improving the practicality of the device.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "surface", "side", "gap", "peripheral", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements 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. Specific Implementation Example 1:

[0030] Reference Figures 1-4 An intake valve pressure adjustment mechanism includes a mounting base 1, with two sets of telescopic guide rods 2 fixedly connected to the bottom of the mounting base 1, and connecting seats 3 fixedly connected to the bottom of each set of telescopic guide rods 2; and a drive adjustment mechanism 4, which includes a reduction motor 401, a rotating shaft 402, a clamping seat 403, a clamping post 404, and a locking bolt 405. The reduction motor 401 is fixedly mounted on the top of the mounting base 1, and the rotating shaft 402 movably passes through the mounting base 1 and is rotatably connected to the mounting base 1. The output end of the reduction motor 401 and the outside of the rotating shaft 402 are connected. Gears 406 are fixedly connected to each of the two connecting seats 3, and the two gears 406 mesh with each other. The top of the mounting seat 403 is fixedly connected to the bottom of the rotating shaft 402. The bottom of the mounting seat 403 has a mounting groove 407 extending into it. The mounting groove 407 is a rectangular groove. The mounting post 404 matches and engages with the mounting groove 407. The mounting seat 403 and the mounting post 404 are locked and fixed by locking bolts 405. A socket wrench 408 is fixedly connected to the bottom of the mounting post 404. The clamping and fixing mechanism 5 is located at the bottom of the two connecting seats 3.

[0031] The top of the mounting base 1 is fixedly connected to two handles 6, which are located near the front and rear sides of the mounting base 1 respectively; the clamping post 404 and the socket wrench 408 are fixedly connected by welding, and the clamping base 403 and the rotating shaft 402 are also fixedly connected by welding.

[0032] In the specific implementation process, when the air pressure adjusting nut of the intake valve cannot be turned by manual torque due to special circumstances, the device can be set up on the top of the intake valve and the pipeline, and the socket wrench 408 can be connected and engaged with the air pressure adjusting nut. At this time, the device can be clamped and fixed to the pipeline by the clamping and fixing mechanism 5. Since the position and height of the clamping and fixing mechanism 5 can be adjusted by the telescopic guide rod 2, it can be used for clamping and fixing the device in a variety of different situations. After the device is clamped and fixed, the reduction motor 401 can be started. The reduction motor 401, in conjunction with two gears 406, drives the rotating shaft 402 to rotate with a large torque. The rotating shaft 402, in conjunction with the clamping seat 403 and the clamping post 404, drives the socket wrench 408 to rotate with a large torque, thereby rotating the air pressure adjusting nut and achieving the purpose of adjusting the air pressure of the intake valve.

[0033] As needed, the locking bolt 405 can be removed, and then the clamping post 404 can be removed from the clamping seat 403. A socket wrench 408 of different size or a wrench tool of different shape can be replaced to make it suitable for various sizes and shapes of air pressure adjusting nuts.

[0034] Among them, the handle 6 makes it convenient for users to move, transfer, and install the device;

[0035] The clamping post 404 and the socket wrench 408 are fixedly connected by welding to ensure that the clamping post 404 and the socket wrench 408 have sufficient connection strength. Similarly, the clamping seat 403 and the rotating shaft 402 are fixedly connected by welding to ensure that the clamping seat 403 and the rotating shaft 402 have sufficient connection strength and are not easily broken or damaged. Specific Implementation Example 2:

[0037] Reference Figure 5 and Figure 6In a preferred embodiment, the clamping and fixing mechanism 5 includes a fixing plate 501, a clamping knob 502, and a clamping block 503. The clamping and fixing mechanism 5 is provided with four sets. The four fixing plates 501 are in pairs, and the two sets of fixing plates 501 are respectively fixedly installed on the bottom of the two connecting seats 3. The four clamping knobs 502 are in pairs, and one end of the two clamping knobs 502 in the same set passes through the two fixing plates 501 by screwing. One side of the four clamping blocks 503 is rotatably connected to the four clamping knobs 502 by a rotating connector. V-shaped grooves are opened on the opposite sides of the two clamping blocks 503 in the same set.

[0038] The bottom of the connecting seat 3 is provided with two sliding grooves 504, and the top of the clamping block 503 is slidably connected to the two sliding grooves 504 through multiple sliding connectors; the inner wall of the V-shaped groove of the clamping block 503 is fitted with an anti-slip pad 505, which is made of rubber material; the fixing plate 501 is made of aluminum alloy material, and the fixing plate 501 is fixedly connected to the connecting seat 3 by welding.

[0039] In the specific implementation process, when working, the device can be first set up on top of the air inlet valve and the pipeline, and the socket wrench 408 can be connected and locked with the air pressure adjusting nut. At this time, the height of the connecting seat 3 can be adjusted by the telescopic guide rod 2 according to actual needs, thereby adjusting the height of the two sets of clamping blocks 503 until the position height of the two sets of clamping blocks 503 matches the position height of the pipeline. Then, the four clamping knobs 502 can be rotated in sequence to drive the two sets of clamping blocks 503 to move until the V-groove of the two sets of clamping blocks 503 is in contact with the outside of the pipeline, and the device can be fixed. Due to the V-groove design of the clamping block 503, it can be used for pipelines of various sizes.

[0040] The top of the clamping block 503 is slidably connected to the two sliding grooves 504 through multiple sliding connectors to improve the stability of the clamping block 503 when it moves, so that the clamping block 503 can be moved and pressed tightly against the pipe without manual assistance.

[0041] Among them, the anti-slip pad 505 can increase the friction between the clamping block 503 and the pipe after they are pressed together, thereby improving the stability of the device after it is clamped and fixed, making it less prone to shaking and moving.

[0042] The fixing plate 501 is made of aluminum alloy to ensure that it has sufficient rigidity and is not easily deformed or damaged. The fixing plate 501 and the connecting seat 3 are fixedly connected by welding to ensure that the fixing plate 501 and the connecting seat 3 have sufficient connection strength and are not easily broken or damaged.

[0043] Working principle: When the air pressure adjusting nut of the intake valve cannot be turned manually due to special circumstances, the device can be set up on top of the intake valve and pipeline, and the socket wrench 408 can be connected and engaged with the air pressure adjusting nut. At this time, the height of the connecting seat 3 can be adjusted by the telescopic guide rod 2 as needed, thereby adjusting the height of the two sets of clamping blocks 503 until the position height of the two sets of clamping blocks 503 matches the position height of the pipeline. Then, the four clamping knobs 502 can be turned in sequence to move the two sets of clamping blocks 503 until the two sets of clamping blocks 503 are aligned. The V-grooves of clamp 503 are all tightly abutted against the outside of the pipe to fix the device. Due to the V-groove design of clamp 503, it can be used for pipes of various sizes. After the device is clamped and fixed, the reduction motor 401 can be started. The reduction motor 401, together with two gears 406, drives the rotating shaft 402 to rotate with a large torque. The rotating shaft 402, together with the clamping seat 403 and the clamping post 404, drives the socket wrench 408 to rotate with a large torque, which in turn rotates the air pressure adjusting nut to achieve the purpose of adjusting the air pressure of the air inlet valve.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
