[0026] Figure 2 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] Embodiment 1:

[0029] See also Figure 1-2 , the utility model provides a technical solution:

[0030] A ball valve that is easy to disassemble comprises a valve body 4, a water inlet pipe 5 is arranged on one side of the valve body 4 for water inlet, and a water outlet pipe 7 is arranged on the other side for water outlet. In order to conveniently control the flow of fluid, a flow control ball 11 is installed inside the valve body 4, the water inlet pipe 5 and the water outlet pipe 7 are respectively extended to the inside of the valve body 4, and a sealing gasket 12 is installed at the part where the two are in close contact with the flow control ball 11, so as to avoid leakage when the fluid flows and achieve a sealing effect;

[0031] In order to ensure the circulation of fluid, a transverse through hole 13 is opened inside the flow control ball 11. At the same time, in order to pressurize the fluid, a reduction section for pressurization is set in the middle section of the through hole 13. A detachable base 6 is installed at the bottom of the flow control ball 11, which is convenient for the base and is conducive to cleaning the inside of the valve body 4. A detachable top seat 2 is provided on the top of the flow control ball 11, which is convenient for the base and is conducive to cleaning the inside of the valve body 4. In order to facilitate the rotation of the flow control ball 11 and realize opening and closing, a connecting rod 9 is installed on its top, so that the connecting rod 9 passes through the top seat 2 (provided with unmarked through holes) and extends to the outside. At the same time, a card 1 not connected to the top seat 2 is installed on the outer wall of the top seat 2, and the connecting rod 9 is vertically passed through the card 1 and matched with its thread (the rotation direction of the thread disassembly is opposite to the direction in which the connecting rod 9 drives the flow control ball 11 to rotate). When the card 1 is rotated, the flow control ball 11 can be driven to rotate by the connecting rod 9. In order to avoid excessive rotation angle and affect fluid transmission, a block 3 for limiting the 190-degree rotation of the card is provided on the outer wall of the top seat 2.

[0032] like Figure 2 As shown:

[0033] The narrowing section protrudes toward the inside of the through hole 13 and forms a V shape, and the protruding hypotenuse of the narrowing section is 45 degrees. The narrowed portion allows the fluid in the water inlet direction to be pressurized and discharged through the narrowed channel.

[0034] like Figure 2 As shown:

[0035] The connecting part 15 is installed on the base 6, and the connecting part 15 is threadedly connected to the bottom end of the valve body 4 to achieve a detachable connection. A ball seat 14 that cooperates with the flow control ball 11 is provided inside the connecting part 15 to facilitate the rotation of the ball without affecting the use.

[0036] like Figure 2 As shown:

[0037] A connector 10 is provided on the top seat 2, and the connector 10 is threadedly connected to the top end of the valve body 4 to achieve a detachable connection.

[0038] like Figure 2 As shown:

[0039] After passing the connecting rod 9 vertically through the card 1, it is fixed by the nut 8 (when the card 1 is rotated to drive the flow control ball 11 to close, its rotation direction is actually the direction of the card 1 thread disassembly, that is, upward movement. The card 1 can be restricted by fixing it with the nut 8) to avoid detachment from the connecting rod 9 and affecting its use.

[0040] Embodiment 2:

[0041] The difference between the embodiment described above and the embodiment described above is that the sealing pad 12 is provided as a waterproof sealing pad, which can further improve the waterproof property and provide a long-term use.

[0042] Working principle:

[0043] When in use, by twisting the card 1, the connecting rod 9 drives the flow control ball 11 to rotate, so that the through hole 13 inside the ball is connected with the water inlet pipe 5 and the water outlet pipe 7, and the fluid can pass smoothly. In this process, the narrowing section in the through hole 13 can make the channel smaller, so that the fluid is pressurized and discharged;

[0044] Due to the setting of the stoppers 3 (two), the rotation angle of the card 1 is limited to 90 degrees (maximum rotation), at which time the flow control ball 11 is completely connected with the water inlet pipe 5 and the water outlet pipe 7 to achieve circulation. When the card 1 is twisted and rotated to reset, the flow control ball 11 completely blocks the water inlet pipe 5 and the water outlet pipe 7 to achieve closure;

[0045] When disassembly is required, remove the nut 8, twist the card 1 to remove it, then twist the top seat 2 to remove it, and twist the base 6 to remove it. At this time, the inside of the valve body 4 is exposed, and the inside or the ball can be cleaned.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
