Description

Technical Field

[0001] The utility model relates to the technical field of ball valves, in particular to a ball valve with a quick disassembly and assembly structure. Background Art

[0002] In my country, ball valves are widely used in industries such as oil refining, long-distance pipelines, water conservancy and municipal administration. They have the function of rotating 90°. The plug body is a sphere with a circular through hole or channel passing through its axis. They are widely used in the fields of water, acid, oil, and natural gas. The ball valve includes a valve body, a ball, and a valve stem. The ball is arranged in the valve body.

[0003] However, the existing ball valves still have some defects. For example, a ball valve with a convenient disassembly and assembly number of CN203202270U has a ball body, i.e., a valve core, which is arranged inside the valve body and the valve body has only an opening at the upper end. During the disassembly and maintenance process, it is rather troublesome to take the ball body out of the valve body. At the same time, in order to ensure the sealing effect of the ball valve, the valve body is usually an integrally formed structure, and the inside of the ball valve can only be maintained through the cover of the upper end opening of the ball valve, which is inconvenient for maintenance personnel to insert tools into the interior for operation.

[0004] Therefore, we propose a ball valve with a quick disassembly structure to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a ball valve with a quick disassembly structure to solve the problem that the existing ball valves on the market are not easy to disassemble and maintain, as mentioned in the above background technology.

[0006] To achieve the above object, the utility model provides the following technical solution: a ball valve with a quick disassembly structure, comprising a first valve body, a second valve body and a cover plate, wherein the cover plate is rotatably connected to a rotating shaft, and the lower end of the rotating shaft is connected to a valve core, and both ends of the first valve body and the second valve body are connected to a butt joint;

[0007] The upper ends of the first valve body and the second valve body are provided with thread grooves matched with fixing bolts, and the other ends of the fixing bolts are screwed into the cover plate;

[0008] A base is provided at the bottom of the first valve body and the second valve body, and the base is connected to the mounting plate through a clamping structure.

[0009] The above technical solution can be used to conveniently remove the ball valve from the mounting plate without the need for additional tools, thereby effectively improving the efficiency of disassembly. The ball valve adopts a combined splicing installation structure, which divides the complete ball valve into three major parts: a first valve body, a second valve body and a cover plate. When the ball valve body needs to be disassembled, the fixing bolts at the upper ends of the first valve body and the second valve body are unscrewed to remove the valve core, thereby facilitating maintenance of the interior of the ball valve body.

[0010] As a preferred technical solution of the utility model, the interior of the butt joint pipe is provided with an internal thread, and the end of the butt joint pipe is provided with a through hole that cooperates with the flange.

[0011] As a preferred technical solution of the utility model, an arc-shaped groove is opened inside the cover plate, a first sealing ring is arranged in the arc-shaped groove, and the ends of the first valve body and the second valve body are connected to the second sealing ring.

[0012] As a preferred technical solution of the utility model, the engaging structure includes a card slot, which is provided at the bottom of the base, and the card slot cooperates with a card block on the upper end of the mounting plate.

[0013] As a preferred technical solution of the utility model, an inner groove is opened inside the base, and a stopper is movably connected in the inner groove, and the stopper is connected to a spring, the stopper is engaged with a clamping block, and the tail end of the stopper is connected to a pull rod.

[0014] As a preferred technical solution of the present utility model, a non-slip pad is also provided at the bottom of the base.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The ball valve is provided with a snap-fit ​​structure at the bottom, which is convenient for removing the ball valve from the mounting plate. The hand pull rod drives the stopper to move, so that the stopper and the block on the upper end of the mounting plate are disengaged, so that the ball valve can be separated from the mounting plate without the need for additional tools, which effectively improves the efficiency of disassembly;

[0017] 2. The ball valve adopts a combined splicing installation structure, which divides the complete ball valve into three parts: the first valve body, the second valve body and the cover plate. When the ball valve body needs to be disassembled, unscrew the fixing bolts on the upper ends of the first valve body and the second valve body, so that the other ends of the fixing bolts are disconnected from the cover plate, so that the cover plate can be pulled out from the space formed by the first valve body and the second valve body, and the first valve body and the second valve body are broken apart to take out the valve core, thereby facilitating the maintenance of the interior of the ball valve body.

[0030] Working principle: When using a ball valve with a quick disassembly structure, when disassembly is required, the hand pull rod 18 drives the stopper 16 to move, so that the stopper 16 is disengaged from the block 14 at the upper end of the mounting plate 13, so that the ball valve can be separated from the mounting plate 13; when the ball valve body needs to be disassembled, the fixing bolts 9 at the upper ends of the first valve body 1 and the second valve body 4 are unscrewed, so that the other end of the fixing bolts 9 is disconnected from the cover plate 5, so that the cover plate 5 can be pulled out from the space formed by the first valve body 1 and the second valve body 4, and the first valve body 1 and the second valve body 4 are broken apart, and the valve core 7 can be taken out;

[0031] Since a first sealing ring 10 is provided inside the cover plate 5, the first sealing ring 10 can improve the sealing between the cover plate 5 and the gap between the upper ends of the first valve body 1 and the second valve body 4, thereby preventing leakage. Similarly, the second sealing ring 20 can fill the gap between the first valve body 1 and the second valve body 4, thereby playing the role of interference fit and plugging leakage. Since an anti-slip gasket 19 is provided at the bottom of the base 11, the anti-slip gasket 19 can increase the friction between the contact surface between the base 11 and the upper end of the mounting plate 13, thereby improving the stability of the installation.
