Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, specifically to a magnetically controlled metal hard-seal ball valve. Background Technology

[0002] A ball valve is a type of valve that controls fluid flow by rotating a ball. It has advantages such as simple structure, good sealing performance, convenient operation, and strong flow capacity.

[0003] Metal hard-seal ball valves are ball valves that use metal materials as the sealing pair. They are characterized by high temperature resistance, high pressure resistance, wear resistance, and stable sealing performance. They are usually used to transport corrosive media, high temperature and high pressure media, and other fluids. In fluids containing particles, some impurities enter the ball and valve seat during transportation. When the valve seat is opened and closed, the ball and valve seat rub against each other, which reduces the service life of the ball valve and is not conducive to the use of metal hard-seal ball valves. Therefore, we propose a magnetically controlled metal hard-seal ball valve. Utility Model Content

[0004] The purpose of this invention is to provide a magnetically controlled metal hard-seal ball valve to solve the problems mentioned in the background art.

[0005] A magnetically controlled metal hard-seal ball valve includes a ball with a valve seat rotatably connected therein. An inlet and an outlet are respectively located on both sides of the ball. A mounting base is installed in both the inlet and outlet. A sealing unit is located on one side of each mounting base. The mounting base is used to install the sealing unit in the ball. The sealing unit includes:

[0006] A connecting seat that fits into a mounting seat, the connecting seat being fixed in the sphere by the mounting seat;

[0007] A sliding seat is slidably connected to the liquid inlet and liquid outlet of the ball;

[0008] The second bonding column is fixedly connected to the inner wall of the sliding seat. The second bonding column is inserted into the valve seat. The side of the second bonding column inserted into the valve seat is set as an arc surface. The second bonding column is used to seal the valve seat.

[0009] A sealing gasket is located on one side of the sliding seat and is in contact with both sides of the valve seat. The sealing gasket is used to provide a secondary seal for the valve seat.

[0010] Preferably, a rotating shaft is fixedly connected to the top end face of the valve seat, and a drive motor is installed above the ball, with the output end of the drive motor connected to the rotating shaft.

[0011] Preferably, a first bonding post is fixedly connected to the inner wall of the connecting seat, and the inner wall of the first bonding post is bonded to the inner wall of the second bonding post.

[0012] Preferably, a guide rod is slidably connected to the inner wall of the connecting seat and the sliding seat, one end of the guide rod is fixedly connected to the sealing gasket, and the guide rod is used to limit the sliding of the sliding seat and the sealing gasket.

[0013] Preferably, a first spring is fixedly connected between the connecting seat and the sliding seat, and the first spring is sleeved on the outer peripheral wall of the guide rod.

[0014] Preferably, a second spring is provided between the guide rod and the sealing gasket, and the second spring is sleeved on the outer peripheral wall of the guide rod.

[0015] Preferably, the mounting base can be configured as mounting bases of different sizes to adjust the installation position of the connecting base.

[0016] By adopting the above technical solution, when the second bonding column is bonded to the valve seat, the sealing performance of the valve seat is effectively guaranteed. Under the rebound of the second spring, the sealing gasket is pushed to bond with the valve seat. Under the action of the sealing gasket, the valve seat is sealed a second time, effectively preventing impurities from entering the valve seat and the ball.

[0017] Compared with the prior art, the beneficial effects of this utility model are: this magnetically controlled metal hard-seal ball valve,

[0018] A ball is provided, and the mounting seat and sealing unit are located on both sides of the mounting ball. Under the rebound of the first spring, the first spring exerts pressure on the sliding seat and the second contact post. When the second contact post is in contact with the valve seat, it effectively ensures the sealing of the valve seat. Under the rebound of the second spring, it pushes the sealing gasket to be in contact with the valve seat. Under the action of the sealing gasket, the valve seat is sealed a second time, effectively preventing impurities from entering the valve seat and the ball.

[0019] When the second bonding column moves, it drives the sliding seat to move as well. The sliding seat compresses the first spring, and the rebound of the first spring causes the first spring to exert pressure on the sliding seat and the second bonding column. When the second bonding column is in contact with the valve seat, it effectively ensures the sealing of the valve seat. When the second bonding column drives the sliding seat to move, the sliding seat drives the second spring to move as well. The second spring then drives the sealing gasket to move, separating the sealing gasket from the valve seat. This prevents the sealing gasket from rubbing against the valve seat, thus avoiding wear on the valve seat and shortening its service life. Attached Figure Description

[0025] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] Please see Figure 1-4 This utility model provides a technical solution: a magnetically controlled metal hard-seal ball valve, including a ball 1, a valve seat 2 rotatably connected in the ball 1, an inlet and an outlet respectively provided on both sides of the ball 1, and a mounting seat 4 installed in both the inlet and outlet. A sealing unit 5 is provided on one side of the mounting seat 4. The mounting seat 4 is used to install the sealing unit 5 in the ball 1. The sealing unit 5 includes:

[0028] The connecting seat 51 fits into the mounting seat 4, and the connecting seat 51 is fixed in the ball 1 by the mounting seat 4;

[0029] The connecting seat 51 is used to install the sliding seat 52, the second bonding post 54 and the sealing gasket 57. By disassembling the connecting seat 51, the sliding seat 52, the second bonding post 54 and the sealing gasket 57 can be replaced.

[0030] The sliding seat 52 is slidably connected to the liquid inlet and liquid outlet of the ball 1;

[0031] The second bonding column 54 is fixedly connected to the inner wall of the sliding seat 52. The second bonding column 54 is inserted into the valve seat 2. The side of the second bonding column 54 inserted into the valve seat 2 is set as an arc surface. The second bonding column 54 is used to seal the valve seat 2.

[0032] The sealing gasket 57 is located on one side of the sliding seat 52. The sealing gasket 57 is in contact with both sides of the valve seat 2 and is used to provide a secondary seal for the valve seat 2.

[0033] By sealing the valve seat 2 with the gasket 57, the valve seat 2 is sealed, effectively preventing impurities in the liquid from entering between the valve seat 2 and the ball 1, which would cause the ball 1 and the valve seat 2 to become stuck, preventing the metal hard-seal ball valve from switching the flow direction normally. At the same time, it also prevents impurities from entering the valve seat 2 and the ball 1, which would cause wear on the valve seat 2.

[0034] A rotating shaft is fixedly connected to the top end face of the valve seat 2. A drive motor 3 is installed above the ball 1. The output end of the drive motor 3 is connected to the rotating shaft. The drive motor 3 is a mature existing technology. The valve seat 2 is precisely steered by magnetic control. This application will not elaborate on this.

[0035] The drive motor 3 is used to control the rotation of the valve seat 2 in the ball 1. The rotation of the valve seat 2 facilitates the opening and closing of the metal hard-seal ball valve.

[0036] A first fitting post 53 is fixedly connected to the inner wall of the connecting seat 51, and the first fitting post 53 fits against the inner wall of the second fitting post 54.

[0037] A guide rod 58 is slidably connected to the inner wall of the connecting seat 51 and the sliding seat 52. One end of the guide rod 58 is fixedly connected to the sealing gasket 57. The guide rod 58 is used to limit the sliding of the sliding seat 52 and the sealing gasket 57.

[0038] When the drive motor 3 starts and controls the valve seat 2 to rotate, the valve seat 2 contacts and presses against the inclined surface of the second contact post 54 under the rotation of the valve seat 2. At this time, the second contact post 54 is pushed, which in turn causes the second contact post 54 to drive the sliding seat 52 to move. The sliding seat 52 slides along the outer peripheral wall of the guide rod 58.

[0039] A first spring 55 is fixedly connected between the connecting seat 51 and the sliding seat 52, and the first spring 55 is sleeved on the outer peripheral wall of the guide rod 58.

[0040] Under the action of the first spring 55, the first spring 55 pushes the sliding seat 52 and the second contacting post 54 to move, so that the second contacting post 54 is inserted into the valve seat 2, ensuring the sealing of the valve seat 2.

[0041] When the second bonding column 54 moves, it drives the sliding seat 52 to move accordingly. At this time, the sliding seat 52 compresses the first spring 55. Under the rebound of the first spring 55, the first spring 55 exerts pressure on the sliding seat 52 and the second bonding column 54. When the second bonding column 54 is in contact with the valve seat 2, it effectively ensures the sealing of the valve seat 2.

[0042] A second spring 56 is provided between the guide rod 58 and the sealing gasket 57, and the second spring 56 is sleeved on the outer peripheral wall of the guide rod 58.

[0043] Under the rebound of the second spring 56, the sealing gasket 57 is pushed to fit against the valve seat 2. Under the action of the sealing gasket 57, the valve seat 2 is sealed a second time, effectively preventing impurities from entering the valve seat 2 and the ball 1.

[0044] When the second contact post 54 moves the sliding seat 52, the sliding seat 52 moves the second spring 56 accordingly. At this time, the second spring 56 moves the sealing gasket 57, and the sealing gasket 57 separates from the valve seat 2, thereby avoiding friction between the sealing gasket 57 and the valve seat 2, which would cause wear on the valve seat 2 and shorten its service life.

[0045] Example 2:

[0046] Please see Figure 1-4 This utility model provides a technical solution: a magnetically controlled metal hard-seal ball valve, including...

[0047] Mounting base 4 can be configured with mounting bases of different sizes to adjust the installation position of connecting base 51. A ball 1 has a valve seat 2 rotatably connected within it. An inlet and an outlet are respectively provided on both sides of the ball 1. Mounting base 4 is installed in both the inlet and outlet. A sealing unit 5 is provided on one side of the mounting base 4. The mounting base 4 is used to install the sealing unit 5 in the ball 1. The sealing unit 5 includes:

[0048] The connecting seat 51 fits into the mounting seat 4, and the connecting seat 51 is fixed in the ball 1 by the mounting seat 4;

[0049] The sliding seat 52 is slidably connected to the liquid inlet and liquid outlet of the ball 1;

[0050] The second bonding column 54 is fixedly connected to the inner wall of the sliding seat 52. The second bonding column 54 is inserted into the valve seat 2. The side of the second bonding column 54 inserted into the valve seat 2 is set as an arc surface. The second bonding column 54 is used to seal the valve seat 2.

[0051] The sealing gasket 57 is located on one side of the sliding seat 52. The sealing gasket 57 is in contact with both sides of the valve seat 2 and is used to provide a secondary seal for the valve seat 2.

[0052] By replacing the mounting base 4 on the ball 1, the mounting base 4 pushes the connecting base 51, changing the initial position of the connecting base 51. At this time, the connecting base 51 compresses the first spring 55. Under the rebound of the first spring 55, the sliding base 52 is pushed to move. At this time, the sliding base 52 compresses the second spring 56. The pressure of the second spring 56 on the sealing gasket 57 increases, improving the sealing performance of the valve seat 2.
