Description

Technical Field

[0001] The utility model belongs to the technical field of balance valves, and particularly relates to an adjustable balance valve assembly. Background Technique

[0002] A compressor balance valve is an automatic control device, and its main function is to change the output pressure of the compressor. When the gas flow or pressure entering the compressor changes, the balance valve will automatically adjust the gas flow and pressure entering the compressor according to the pressure difference to maintain the balance state of the system. The adjustment process of the balance valve is achieved by using static pressure, spring force, and feedback signals.

[0003] The balance valve mainly consists of components such as a valve body, a valve core, and an adjustment handle. During the long-term use of the existing valve core, wear will occur on the surface of the valve core, resulting in poor sealing between the valve core and the valve body. To ensure the effective use of the balance valve, generally, the entire balance valve will be directly replaced, which not only wastes resources but also increases the use cost, thus making it inconvenient for people to use. Content of the Utility Model

[0004] The purpose of the utility model is to provide an adjustable balance valve assembly with a simple structure and reasonable design to solve the above problems.

[0005] The utility model realizes the above purpose through the following technical solutions:

[0006] An adjustable balance valve assembly includes a valve body, a through hole opened in the valve body, and an installation cylinder installed at the top of the valve body and arranged obliquely. A fixing cylinder is detachably installed outside the installation cylinder. A valve pipe is installed on one side of the fixing cylinder. A valve rod is threadedly connected inside the valve pipe. The bottom of the valve rod passes through the fixing cylinder and extends into the through hole and is detachably installed with a valve core. An intercepting member is arranged in the through hole. A circulation port for cooperating with the valve core is opened on the intercepting member. The top end of the valve rod extends to the top of the valve pipe and is installed with a rotating disk.

[0007] As a further optimized scheme of the utility model, an external thread is arranged outside the installation cylinder, and an internal thread for cooperating with the external thread is arranged on the inner wall of the fixing cylinder.

[0008] As a further optimized scheme of the utility model, a threaded rod is installed at the top of the valve core. A threaded cavity for cooperating with the threaded rod is opened at the bottom of the valve rod. A flared opening is opened at the bottom of the threaded cavity. A fixing mechanism is installed on the threaded rod, and a pressing mechanism for cooperating with the fixing mechanism is arranged on the valve rod.

[0009] As a further optimized solution of the present utility model, the fixing mechanism includes an installation cavity opened in the threaded rod, two sliding plates slidably connected in the installation cavity, and a first spring installed between the two sliding plates. Fixed rods extending to the outside of the threaded rod are installed on one side of each of the two sliding plates away from each other. Ball bearings are rotatably connected to one end of each of the two fixed rods, and two clamping grooves for cooperating with the fixed rods are opened on the inner wall of the threaded cavity.

[0010] As a further optimized solution of the present utility model, the pressing mechanism includes pressing components installed on both sides of the valve rod and corresponding to each other. The pressing component includes a pressing plate, a pressing rod installed on one side of the pressing plate, and a second spring sleeved outside the pressing rod. Two ends of the second spring are respectively fixedly connected to the pressing plate and the outside of the valve rod, and the pressing rod extends into the clamping groove.

[0011] As a further optimized solution of the present utility model, a sealing plate that fits the inner wall of the installation cylinder is installed on the inner wall of the top of the fixed cylinder, and an opening for facilitating the valve rod to pass through is opened at the center of the sealing plate.

[0012] As a further optimized solution of the present utility model, two pressure gauges are installed on the valve body and located on both sides of the installation cylinder.

[0013] The beneficial effect of the present utility model is that during the use of the present utility model, when the outer surface of the valve core is worn, only the valve core can be replaced, which reduces the waste of resources, saves the use cost, and thus is more convenient for people to use.

Specific implementation manner

[0022] The present application will be further described in detail below with reference to the accompanying drawings. It is necessary to point out here that the following specific implementation manners are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0023] As Figure 1 - Figure 3 shown, an adjustable balance valve assembly includes a valve body 1, a through hole 2 opened in the valve body 1, and a mounting cylinder 3 installed at the top of the valve body 1 and inclined. A fixing cylinder 4 is detachably installed outside the mounting cylinder 3. Two pressure gauges 7 are installed on the valve body 1 on both sides of the mounting cylinder 3. The outside of the mounting cylinder 3 is provided with an external thread, and the inner wall of the fixing cylinder 4 is provided with an internal thread that cooperates with the external thread. A valve pipe 5 is installed on one side of the fixing cylinder 4. A valve rod 8 is threadedly connected inside the valve pipe 5. The bottom of the valve rod 8 passes through the fixing cylinder 4 and extends into the through hole 2 and is detachably installed with a valve core 10. An intercepting member 21 is arranged in the through hole 2, and a flow port 22 that cooperates with the valve core 10 is opened on the intercepting member 21. The top of the valve rod 8 extends to the top of the valve pipe 5 and is installed with a rotating disk 6. The top of the valve core 10 is installed with a threaded rod 11. A threaded cavity 12 that cooperates with the threaded rod 11 is opened at the bottom of the valve rod 8. A rubber sealing layer is arranged outside the valve core 10, thereby improving the sealing performance between the valve core 10 and the flow port 22;

[0024] During use, the rotating disk 6 can be rotated, and the valve rod 5 will move inside the valve pipe 5. When the valve rod 5 moves, it will drive the valve core 10 to move inside the flow port 22, thereby adjusting the flow rate of gas or liquid in the through hole 2 and making the pressure in the channels at both ends of the valve body 1 relatively balanced;

[0025] As Figure 2 shown, a sealing plate 9 that fits the inner wall of the mounting cylinder 3 is installed on the top inner wall of the fixing cylinder 4, and an opening for the valve rod 8 to pass through is opened at the center of the sealing plate 9;

[0026] By providing the sealing plate 9, the connection between the mounting cylinder 3 and the fixing cylinder 4 can be sealed, thereby improving the sealing performance of the balance valve during use and reducing the occurrence of liquid leakage.

[0027] As Figure 1 - Figure 7 shown, a fixing mechanism is installed on the threaded rod 11, and a pressing mechanism cooperating with the fixing mechanism is provided on the valve rod 8. The fixing mechanism includes an installation cavity 16 opened in the threaded rod 11, two sliding plates 18 slidably connected in the installation cavity 16, and a first spring 17 installed between the two sliding plates 18. Fixing rods 19 extending to the outside of the threaded rod 11 are installed on one side of the two sliding plates 18 away from each other. Ball bearings 20 are rotatably connected to one end of the two fixing rods 19. By providing the ball bearings 20, the friction generated between the fixing rod 19 and the inside of the threaded cavity 12 during the rotation of the threaded rod 11 can be reduced, thereby increasing the service life of the fixing rod 19. Two card slots 23 cooperating with the fixing rod 19 are opened on the inner wall of the threaded cavity 12. The pressing mechanism includes pressing components installed on both sides of the valve rod 8 and corresponding to each other. The pressing component includes a pressing plate 13, a pressing rod 15 installed on one side of the pressing plate 13, and a second spring 14 sleeved outside the pressing rod 15. The two ends of the second spring 14 are respectively fixedly connected to the pressing plate 13 and the outside of the valve rod 8, and the pressing rod 15 extends into the card slot 23. A trumpet-shaped opening is opened at the bottom of the threaded cavity 12. By providing the opening, it is convenient to receive the fixing rod 19 into the threaded cavity 12, and thus it is convenient to install the threaded rod 11;

[0028] During the use process, when it is necessary to replace the valve core 10, the fixing cylinder 4 can be rotated, so that the fixing cylinder 4 is screwed off from the outside of the installation cylinder 3. After being screwed off, the pressing plate 13 is pushed towards the valve rod 8. At this time, the pressing plate 13 will compress the second spring 14, so that the pressing rod 15 will push the fixing rod 19 to move, so as to push the fixing rod 19 into the threaded cavity 12. Then the threaded rod 11 is rotated, so that the threaded rod 11 is taken out from the inside of the threaded cavity 12. When it is necessary to install a new valve core 10 on the valve rod 8, the threaded rod 11 is rotated. At this time, the fixing rod 10 will move towards the inside of the threaded cavity 12 along the opening, so that the two fixing rods 19 will compress the first spring 17 and rotate inside the threaded cavity 12. When it is screwed to the position where the fixing rod 19 corresponds to the card slot, under the action of the elastic force of the first spring 17, the fixing rod 19 will be directly located in the card slot, so as to fix the threaded rod 11 at the bottom of the valve rod 8. During the use process, not only can the valve core 10 be replaced, but also when the valve rod 8 is damaged, a new valve rod 8 can be replaced.

[0029] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model.
