Description

Technical Field

[0001] The utility model relates to the technical field of ball valves, in particular to an easily disassembled ball valve. Background Art

[0002] Ball valve is a valve whose opening and closing part (ball) is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control. The hard-sealed V-type ball valve has a strong shear force between its V-type ball core and the metal valve seat with hard alloy surfacing, which is particularly suitable for media containing fibers, tiny solid particles, etc. The multi-way ball valve can not only flexibly control the confluence, diversion, and flow direction switching of the medium on the pipeline, but also close any channel to connect the other two channels. This type of valve should generally be installed horizontally in the pipeline. Ball valves are divided into: pneumatic ball valves, electric ball valves, and manual ball valves according to the driving method.

[0003] The ball valve was introduced in the 1950s. With the rapid development of science and technology, the continuous improvement of production technology and product structure, it has rapidly developed into a major valve type in just 40 years. In Western industrially developed countries, the use of ball valves is increasing year by year.

[0004] For example, the authorization announcement number "CN214466273U" is called an easy-to-disassemble ball valve. Although the detachable valve stem can reduce maintenance costs during maintenance, it is also more convenient to disassemble and assemble. However, there are many factors that may cause ball valve damage. For ball valves in PPR pipes, they usually need to be replaced as a whole. The usual replacement method is to first cut off the PPR pipes at both ends of the ball valve. When replacing, the two ends of the ball valve need to be connected to a section of PPR pipe, and then the ball valve and the PPR pipe are hot-melt connected. The original pipe will be damaged during replacement, and non-professionals cannot install, disassemble or replace it; the ball valve is easily misoperated by unrelated personnel, resulting in adverse consequences.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-5A ball valve that is easy to disassemble and assemble comprises a ball valve body 1. First tube walls 2 are arranged on both side surfaces of the ball valve body 1. Second tube walls 3 are arranged on the ends of the two first tube walls 2 away from the ball valve body 1. Pipe connecting devices are arranged between the adjacent first tube walls 2 and the second tube walls 3. An installation cavity 4 is arranged inside the ball valve body 1. First cavities 5 are arranged inside the two first tube walls 2. The installation cavity 4 is communicated with the two first cavities 5. Second cavities 6 are arranged inside the two second tube walls 3. Two adjacent first cavities 5 are communicated with the second cavity 6. Filtering devices are arranged inside the two first cavities 5. A valve core 7 is arranged inside the installation cavity 4. A ball valve opening and closing device is arranged on the upper surface of the valve core 7. A core cavity 8 is arranged inside the valve core 7. When the core cavity 8 is communicated with the first cavity 5, the ball valve is in a connected state; when the core cavity 8 is not communicated with the first cavity 5, the ball valve is in a closed state.

[0022] The pipe connection device includes a first protrusion 9 and a second protrusion 10. The first protrusion 9 is annularly arranged on the surface of the first pipe wall 2, and the second protrusion 10 is annularly arranged on the surface of the second pipe wall 3. The first pipe wall 2 and the first protrusion 9 are integrally formed, so that the first pipe wall 2 and the first protrusion 9 are more firmly connected. The second pipe wall 3 and the second protrusion 10 are integrally formed, so that the second pipe wall 3 and the second protrusion 10 are more firmly connected. A plurality of first mounting holes 11 are arranged on the surface of the first protrusion 9, and a plurality of second mounting holes 12 are arranged on the surface of the second protrusion 10. The plurality of first mounting holes 11 correspond to the plurality of second mounting holes 12 one by one. Bolts 13 are arranged inside the first mounting holes 11 and the second mounting holes 12. Since the plurality of first mounting holes 11 correspond to the plurality of second mounting holes 12 one by one, it is ensured that the bolts 13 can pass through the first mounting holes 11 and the second mounting holes 12 at the same time. Nuts 14 are sleeved on the outside of the plurality of bolts 13, and screw holes 15 are arranged on the surface of the plurality of nuts 14. The plurality of bolts 13 are threadedly connected with the plurality of screw holes 15.

[0023] During installation, the bolt 13 is extended from the first mounting hole 11 and the second mounting hole 12, and then the bolt 13 is tightened clockwise. Through the threaded connection between the bolt 13 and the screw hole 15, the first pipe wall 2 and the second pipe wall 3 can be tightly connected, and the ball valve is installed; during disassembly, the bolt 13 is loosened and removed counterclockwise to remove the ball valve. Through the above operations, for the ball valve in the PPR pipeline, there is no need to cut off the PPR pipelines at both ends of the ball valve, and non-professionals can also complete the installation, disassembly and replacement.

[0024] A gasket 16 is provided between the first protrusion 9 and the second protrusion 10 to provide a better sealing effect and prevent water seepage.

[0025] A positioning groove 17 is provided in an annular manner at one end of the first pipe wall 2 away from the ball valve body 1, and a positioning block 18 is provided in an annular manner at one end of the second pipe wall 3 close to the first pipe wall 2, and the positioning groove 17 matches the positioning block 18. Since the PPR pipe has a certain toughness, when installing, the PPR pipes at both ends of the ball valve are first slightly moved outward, and then the positioning block 18 is inserted into the positioning groove 17, which plays a positioning role, facilitates installation, and avoids misalignment of the first pipe wall 2 and the second pipe wall 3 during installation, resulting in water seepage.

[0026] The ball valve opening and closing device includes a vertical rod 19, a through hole 20 is provided on the upper surface of the ball valve body 1, the vertical rod 19 extends out of the through hole 20, a sealing block 21 is provided on the inner wall of the ball valve body 1, a sealing hole 22 is provided on the surface of the sealing block 21, the through hole 20 is communicated with the sealing hole 22, a handle 23 is sleeved on the outside of the vertical rod 19, a handle hole 24 is provided on the surface of the handle 23, the vertical rod 19 extends out of the handle hole 24, a limit block 25 is provided above the handle 23, a limit hole 26 is provided on the surface of the limit block 25, the vertical rod 19 extends out of the limit hole 26, the vertical rod 19 is threadedly connected to the limit hole 26, so as to facilitate the installation and removal of the handle 23, a locking block 27 is provided between the upper surface of the ball valve body 1 and the lower surface of the handle 23, a locking hole 28 is provided on the surface of the locking block 27, and the vertical rod 19 is threadedly connected to the locking hole 28.

[0027] Working principle: When the ball valve needs to be locked in the connected state or the closed state, the locking block 27 only needs to be rotated clockwise. Since the vertical rod 19 is threadedly connected with the lock hole 28, the locking block 27 moves downward. When the locking block 27 presses the upper surface of the ball valve body 1, it is in the locked state, and the handle 23 will not rotate, preventing unauthorized personnel from misoperating and causing adverse consequences. When the ball valve is in the connected state, the handle 23 is first rotated to drive the vertical rod 19 through the handle 23, and then drive the valve core 7. When the core cavity 8 is not connected with the first cavity 5, the handle 23 is perpendicular to the first tube wall 2, and the ball valve is in the closed state; on the contrary, the handle 23 is rotated to drive the vertical rod 19 through the handle 23, and then drive the valve core 7. When the core cavity 8 is connected with the first cavity 5, the handle 23 is parallel to the first tube wall 2, and the ball valve is in the connected state.

[0028] The filter device includes a filter screen 29, and a mesh cavity 30 is provided inside the filter screen 29. The filter screen 29 can effectively filter out impurities in the pipeline, and the mesh cavity 30 can ensure the flow rate of water in the pipeline, and the flow rate of water in the pipeline will not be reduced due to the filter screen; at the same time, the filter screen 29 is arranged inside the first cavity 5, which is convenient for disassembly and installation.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
