[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. This pressure-resistant and corrosion-resistant water supply and drainage ball valve, when the pressure inside the valve housing is too high, the pressure pushes the top plate, causing the top plate to drive the connecting column, cross bar and slider to move, so that the top plate enters the middle section of the inner wall of the fixed pipe.

[0013] 2. This pressure-resistant and corrosion-resistant water supply and drainage ball valve rotates the rotating ring, which drives the threaded rod to move inside the rotating ring. The threaded rod drives the lock head to move, so that the lock head is disengaged from the insertion rod. At this time, the fixed relationship of the insertion rod disappears. Pull the filter upward and take out the filter together with the insertion rod. Take out the unused filter, insert the insertion rod at the bottom into the notch at the top of the fixed seat, so that the circular groove on the outer wall of the insertion rod is parallel to the lock head, reset the lock head, and complete its replacement.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] See also Figure 1 - Figure 5 , a pressure-resistant and corrosion-resistant water supply and drainage ball valve comprises a fixed seat 1, a valve housing 2 is fixedly installed on the top of the fixed seat 1, a fixed block 3 is fixedly assembled on the top of the valve housing 2, the inner wall of the fixed block 3 is rotatably connected to the rotating shaft 4, the outer wall of the valve housing 2 is provided with a pressure relief assembly 5, and a rotating valve ball 6 is fixedly installed on the bottom of the rotating shaft 4. The inner wall of the valve housing 2 is slidably connected to the filter screen 7, and the outer wall of the filter screen 7 is fixedly installed with a sealing strip 8. The outer wall of the fixed seat 1 is fixedly installed with a fixed sleeve 9, and the outer wall of the fixed sleeve 9 is rotatably connected to a rotating ring 10. The inner wall of the fixed sleeve 9 is slidably connected to a lock head 12, and the bottom of the filter screen 7 is fixedly installed with an inserted rod 13, and the lock head 12 is fixedly installed with a threaded rod 11 on the side close to the rotating ring 10. In the above structure, the inner wall of the valve housing 2 is provided with an anti-corrosion paint, so that the inner wall of the valve housing 2 will not rust due to long-term use during use.
[0023] In a preferred embodiment, the pressure relief assembly 5 includes a fixed tube 501, the inner wall of which is fixedly mounted a guide rail 502, the outer wall of which is slidably sleeved with a slider 503, the inner wall of which is fixedly mounted a cross bar 504, the outer wall of which is fixedly mounted one end of a connecting column 505, the other end of which is fixedly mounted a top plate 506, and the outer wall of the guide rail 502 is provided with a spring 507. In the above structure, when the internal pressure of the valve housing 2 is too high, the pressure pushes the top plate 506, causing the top plate 506 to move toward the inside of the fixed tube 501, thereby driving the connecting column 505, the cross bar 504 and the slider 503 to move, thereby causing the slider 503 to move toward the spring 507, causing the spring 507 to contract. At this time, since the inner wall diameter of the fixed tube 501 is larger than the top plate 506, the internal gas or liquid is discharged from the gap between the top plate 506 and the fixed tube 501, thereby causing the pressure inside the valve housing 2 to be discharged.
[0024] In a preferred embodiment, the guide rail 502 passes through the slider 503, and the number of the guide rails 502 and the slider 503 is two. The two guide rails 502 and the slider 503 are symmetrically distributed on the inner wall of the fixed tube 501, and the two sliders 503 are connected by a cross bar 504. In the above structure, the slider 503 is limited by the guide rail 502, so that the guide rail 502 can only move on the outer wall of the guide rail 502.
[0025] In a preferred embodiment, the threaded rod 11 is located on the inner wall of the rotating ring 10, and the inner wall of the rotating ring 10 is provided with a thread. The rotating ring 10 is threadedly connected to the outer wall of the threaded rod 11 through the thread on the inner wall. In the above structure, by rotating the rotating ring 10, the thread on the inner wall of the rotating ring 10 rotates, thereby driving the threaded rod 11 to move up and down on the inner wall of the rotating ring 10.
[0026] In a preferred embodiment, an extension block is provided on the top of the lock head 12, and the extension block on the top of the lock head 12 is adapted to the inner wall of the threaded rod 11. In the above structure, the lock head 12 is limited by the extension block on the top of the lock head 12, so that the lock head 12 will not rotate with the rotational force of the rotating ring 10 when it moves.
[0027] In a preferred embodiment, a notch is provided at the top of the fixing seat 1, and the size of the notch is adapted to the insertion rod 13, and a circular groove is provided on the outer wall of the insertion rod 13, and the diameter of the circular groove is adapted to the diameter of the lock head 12. In the above structure, by placing the insertion rod 13 in the notch at the top of the fixing seat 1 and moving it downward to the bottom, the circular groove on the outer wall of the insertion rod 13 reaches the outside of the lock head 12, and the lock head 12 is moved to the circular groove on the outer wall of the insertion rod 13, so that the insertion rod 13 is fixed by the lock head 12.
[0028] Working principle: when the device is used, by rotating the rotating shaft 4, the rotating shaft 4 drives the rotating valve ball 6 to rotate, and the direction of the port of the rotating valve ball 6 is controlled to open and close it. The liquid passes through the rotating valve ball 6 to reach the filter screen 7 and is filtered by the filter screen 7. When the internal pressure of the valve housing 2 is too high, the pressure will push the top plate 506, causing the top plate 506 to move toward the inside of the fixed tube 501, thereby driving the connecting column 505, the cross bar 504 and the slider 503 to move, thereby causing the slider 503 to move toward the spring 507, contracting the spring 507. At this time, since the inner wall diameter of the fixed tube 501 is larger than the top plate 506, the internal gas or liquid is discharged from the gap between the top plate 506 and the fixed tube 501, thereby discharging the pressure inside the valve housing 2, so that the valve housing 2 will not be damaged due to excessive internal pressure. When the filter screen needs to be repaired, the filter screen will be cleaned. The rotating ring 10 drives the threaded rod 11 to move toward the insertion rod 13, and the insertion rod 13 drives the lock head 12 to move toward the circular groove of the outer wall of the insertion rod 13, fixing the insertion rod 13, and completing the replacement of the filter 7.
[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
