Description

Technical Field

[0001] This utility model belongs to the field of valve technology, and in particular relates to a valve structure that is easy to disassemble. Background Technology

[0002] A valve is a common mechanical device mainly used to control fluids, thereby achieving functions such as cutting off or connecting fluids, controlling flow or pressure, preventing backflow, diverting or mixing fluids. Valves are mainly composed of valve bodies, valve covers, opening and closing parts, valve stems, sealing systems, and drive devices.

[0003] The existing authorization announcement document with CN220082245U discloses a valve that is easy to disassemble, including a valve body, with a first flange fixedly connected to both ends of the valve body, a second flange provided on the side of the first flange away from the valve body, a pipe fixedly connected to the side of the second flange away from the first flange, and a limit block provided on one side of both second flanges and above the pipe.

[0004] However, it still has the following drawbacks in practical use:

[0005] 1. In the valves mentioned above, the opening and closing components inside the valve body are generally installed inside the valve body by snap-fit. In order to ensure its sealing performance, the size of the opening and closing components is almost the same as the size of the internal space of the valve body, which makes it inconvenient to install and disassemble the opening and closing components.

[0006] 2. The valve body described above is connected to an external pipeline via a first flange and a second flange. However, since the distance between the first flange and the valve body is fixed, it is inconvenient to install between pipelines with different distances, thus making it inconvenient to connect the valve body to the pipeline.

[0007] To address these issues, we provide a valve structure that is easy to disassemble. Utility Model Content

[0008] The purpose of this utility model is to provide a valve structure that is easy to disassemble. The ball is installed in the valve body by means of a bottom cover, and the bottom cover is locked to the bottom of the valve body by a rotating strip, which facilitates the installation and disassembly of the ball and solves the problem of the ball being inconvenient to disassemble in the existing system. At the same time, the first and second sleeve plates are driven to move relative to each other by the sleeve and the threaded rod, which makes it easy to install the valve body between pipes with different spacings, and solves the problem of the valve body being inconvenient to install between pipes with different spacings in the existing system.

[0013] A further feature of this invention is that: sealing rings are fixedly connected to the inner walls of both sides of the valve body, and the ends of the sealing rings away from the inner wall of the valve body are respectively attached to the two sides of the ball. A valve stem is movably connected to the upper part of the valve body through a valve cover. The bottom end of the valve stem is snapped into the top of the ball, and a handle is fixedly connected to the top end of the valve stem.

[0014] A further feature of this invention is that a groove is provided on the top of the ball, and a protrusion fits into the internal gap of the groove, with the top of the protrusion welded to the bottom of the valve stem.

[0015] A further feature of this invention is that: a mounting block is welded to the top of the valve stem, the mounting block is fitted with a through groove located at the center of the handle surface, a third fixing rod is welded to the top of the mounting block, a third fastening nut is threaded to the top of the third fixing rod, and the third fastening nut is attached to the top of the handle.

[0019] This utility model has the following beneficial effects:

[0020] 1. This utility model, by setting up a main component, allows the first fastening nut to be tightened, causing it to separate from the rotating bar. The rotating bar is then rotated, causing it to separate from the first fixed rod, and a downward force is applied to the bottom cover. This causes the bottom cover to pull the ball off the valve body, thus achieving the disassembly of the ball. This facilitates the replacement of the ball inside the valve body and makes it easier to inspect and replace valve components.

[0021] 2. By setting up a connecting component, rotating the sleeve causes the second sleeve plate to move relative to the first sleeve plate through the threaded rod, which in turn causes the connecting pipe to move relative to the valve body. The connecting pipe is then connected to an external pipe through a flange, enabling the valve to be installed between adjacent pipes with different spacings. This facilitates the connection between the valve and the pipe, expands its application range, and improves its practicality. Attached Figure Description
