Description

Technical Field

[0001] The utility model relates to the technical field of ball valves, in particular to a leakage-proof straight-tube regulating ball valve. Background Art

[0002] The opening and closing parts of the ball valve are driven by the valve stem and rotate around the axis of the ball valve. They are used for regulating and controlling fluids.

[0003] When connecting straight pipes, a ball valve is installed between two sections of straight pipes, and the fluid transported in the straight pipe is regulated and controlled by the ball valve. The ball valve in the prior art controls the fluid by rotating the ball to control the connection or sealing of the ball and the straight pipe. In order to ensure the sealing effect of the ball on the fluid in the straight pipe, a sealing gasket is provided inside the ball valve, and the sealing gasket fits with the ball to seal the fluid. However, in a working environment where the ball valve is frequently used, the rotation of the ball and the friction with the sealing gasket cause the sealing gasket to wear, thereby affecting the sealing effect of the ball valve. When it is necessary to continue to ensure the sealing effect of the ball, the ball valve needs to be disassembled and replaced with a new one. The ball valve is directly scrapped and cannot be reused, resulting in high consumption of the ball valve. Therefore, we propose a leak-proof straight pipe regulating ball valve. Utility Model Content

DETAILED DESCRIPTION

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The embodiment of the present application provides a leakage-proof straight pipe regulating ball valve, which solves the problem that the rotation of the ball 3 and the friction with the sealing gasket 401 cause the sealing gasket 401 to wear, thereby affecting the sealing effect of the ball valve 1. When it is necessary to continue to ensure the sealing effect of the ball 3, the ball valve 1 needs to be disassembled and replaced with a new ball valve 1, and the ball valve 1 is directly scrapped and cannot be reused. The flange seat 2 is installed on the ball valve 1. Under the action of the flange seat 2, the flange seat 2 is brought into contact with and squeezed with the extrusion seat 405, and the spring 404 is compressed by the extrusion seat 405. Under the rebound of the spring 404, the sealing gasket 401 is pushed to fit tightly with the ball 3. Under the action of the sealing gasket 401, the ball 3 is sealed to prevent leakage. When the sealing gasket 401 is worn, the flange seat 2 can be disassembled to remove the sealing gasket 401 in the ball valve 1. The sealing gasket 401 can be disassembled and replaced with a new sealing gasket 401 to ensure its sealing and prevent leakage again.

[0024] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] The utility model embodiment discloses an anti-leakage straight pipe regulating ball valve.

[0026] According to the attached Figure 1-4 As shown, it includes a ball valve 1, both sides of the ball valve 1 are connected with a flange seat 2 by bolts, the ball valve 1 is internally connected with a ball 3, and the ball valve 1 is opened or closed by rotating the ball 3. Between the flange seat 2 and the ball 3 are arranged:

[0027] The sealing unit 4 includes a sealing gasket 401 fitted with the ball 3 and an extrusion seat 405 fitted with the flange seat 2. A plurality of springs 404 are arranged between the sealing gasket 401 and the extrusion seat 405. The sealing gasket 401 is installed on the ball valve 1 through the flange seat 2. Under the action of the flange seat 2, the flange seat 2 is brought into contact with and extruded from the extrusion seat 405. The spring 404 is compressed through the extrusion seat 405. Under the rebound of the spring 404, the sealing gasket 401 is pushed to fit tightly with the ball 3. Under the action of the sealing gasket 401, the ball 3 is sealed to prevent leakage. When the sealing gasket 401 is worn, the sealing gasket 401 in the ball valve 1 can be taken out by disassembling the flange seat 2. The sealing gasket 401 can be disassembled and replaced with a new one to ensure its sealing performance and prevent leakage.

[0028] The installation unit 5 includes a sliding frame 501 fixed to the extrusion seat 405, and a fitting frame 502 is slidably connected to the inner wall of the sliding frame 501. The fitting frame 502 is slidably connected to the inner wall of the sliding frame 501, and the sliding frame 501 fits with the inner wall of the flange seat 2, and cooperates with the connecting seat 503 and the fitting frame 502 to perform secondary sealing on the ball valve 1, thereby improving the sealing effect and preventing leakage.

[0029] The upper and lower ends of the spherical body 3 are rotatably connected to a rotating seat 301 , and the rotating seat 301 is fixedly connected to the ball valve 1 .

[0030] Both sides of the rotating seat 301 are fixedly connected with plug blocks 302, and the outer peripheral wall of the plug block 302 is plugged with a positioning frame 303. The positioning frame 303 is fixedly connected to the sealing gasket 401. By disassembling the flange seat 2, the newly installed sealing gasket 401 is slidably connected to the ball valve 1, so that the positioning frame 303 is sleeved on the outer peripheral wall of the plug block 302. Under the action of the rotating seat 301 and the plug block 302, the position of the sealing gasket 401 is positioned.

[0031] A mounting seat 402 is installed on the outer wall of the sealing gasket 401, and a contact seat 403 is fixedly connected to the outer wall of the mounting seat 402. The sealing gasket 401 is installed on the mounting seat 402 by bolts. The sealing gasket 401 can be replaced by removing the sealing gasket 401 and then installing a new sealing gasket 401 on the mounting seat 402, thereby ensuring the sealing performance of the sealing gasket 401 again.

[0032] The contact seat 403 is fixedly connected to a plurality of springs 404, and the other end of the spring 404 is fixedly connected to the extrusion seat 405. By sliding the sealing gasket 401 in the ball valve 1 and then installing the flange seat 2 on the ball valve 1, the flange seat 2 makes contact with and squeezes the extrusion seat 405 under the action of the flange seat 2, compressing the spring 404.

The mounting seat 402 is connected to the connecting seat 503 through the connection between the mounting seat 402 and the bonding frame 502. When the sliding frame 501 and the bonding frame 502 slide, the movement of the mounting seat 402 and the connecting seat 503 is limited, so that the movement of the sealing gasket 401 installed with the mounting seat 402 is more stable.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
