DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0020] Please refer to Figures 1 - 3, a fire hydrant valve with a fireproof double-sealing structure, including a valve body 1. An installation seat 11 is fixedly arranged at the top of the valve body 1. A second jack 112 is opened on the left side of the installation seat 11, and a first jack 111 is opened on the rear side of the installation seat 11. A valve plate 21 is rotatably arranged inside the valve body 1. A group of connecting rods 23 are fixedly arranged on both the left and right sides of the valve plate 21. A group of sealing plates 24 are fixedly arranged on the opposite sides of the two groups of connecting rods 23. A group of second high-temperature resistant sealing gaskets 25 are fixedly arranged on the opposite sides of the two groups of sealing plates 24. A first high-temperature resistant sealing gasket 22 is fixedly arranged on the outer side wall of the valve plate 21. The outer side walls of the first high-temperature resistant sealing gasket 22 and the second high-temperature resistant sealing gasket 25 are in contact with the inner side wall of the valve body 1. The two groups of second high-temperature resistant sealing gaskets 25 correspond to the water inlet and outlet of the valve body 1 respectively. The valve plate 21 separates and seals the inner cavity of the valve body 1 through the first high-temperature resistant sealing gasket 22. The two groups of sealing plates 24 seal the water inlet and outlet of the valve body 1 respectively through the second high-temperature resistant sealing gaskets 25 on the outside, thereby double-sealing the inside of the valve body 1, and effectively preventing the occurrence of water leakage inside the valve body 1 due to poor sealing. A turntable 12 is rotatably arranged on the top of the installation seat 11. A rotating rod 2 is fixedly arranged at the bottom of the turntable 12. The rotating rod 2 passes through the bottom of the installation seat 11 and the top of the valve body 1 and is connected to the valve plate 21. A limiting rod 14 is fixedly arranged on the right side of the top of the installation seat 11. A limiting groove 15 is opened through the top of the turntable 12. The limiting rod 14 is slidably arranged in the limiting groove 15. A square rod 16 is fixedly arranged on the left side of the turntable 12. A limiting disk 18 is fixedly arranged on the left side of the square rod 16. A spring 17 is placed on the outer circle of the square rod 16. A handle 13 is placed on the left side of the turntable 12. A square groove is opened on the right side of the handle 13, and a guiding groove is opened on the left side of the square groove. The square rod 16 is slidably arranged in the square groove. The limiting disk 18 is slidably arranged in the guiding groove. The spring 17 is fixedly arranged between the turntable 12 and the handle 13. A bolt 19 is fixedly arranged on the right side of the handle 13. The bolt 19 is inserted into the second jack 112 and corresponds to the first jack 111. When water needs to be taken from the valve body 1 for fire extinguishing, pull the handle 13 to the left to drive the bolt 19 to separate from the second jack 112. At this time, the spring 17 is in a stretched state. The outer pulling distance of the handle 13 is limited by the limiting disk 18. Then push the handle 13 backward to drive the turntable 12 to rotate through the square rod 16. The rotation angle of the turntable 12 can be limited by the sliding of the limiting rod 14 in the limiting groove 15. The turntable 12 drives the valve plate 21 to rotate through the rotating rod 2. The valve plate 21 drives the sealing plates 24 to rotate through the connecting rods 23, so that the two groups of sealing plates 24 are misaligned with the water inlet and outlet of the valve body 1, and then the valve body 1 can be quickly opened. At this time, the bolt 19 is aligned with the first jack 111 as the handle 13 rotates. When the handle 13 is released, the spring 17 uses its own resilience to drive the bolt 19 to insert into the first jack 111 through the handle 13, thereby completing the position fixation of the valve plate 21 and the sealing plates 24.
[0021] Working principle: The valve plate 21 separates and seals the inner cavity of the valve body 1 through the first high-temperature resistant gasket 22. The two groups of sealing plates 24 respectively seal the water inlet and outlet of the valve body 1 through the second high-temperature resistant gaskets 25 on the outside, thereby double-sealing the inside of the valve body 1, and effectively preventing water leakage caused by poor sealing inside the valve body 1. When it is necessary to draw water from the valve body 1 for fire extinguishing, pull the handle 13 to the left to drive the bolt 19 to separate from the second jack 112. At this time, the spring 17 is in a stretched state, and the outer pulling distance of the handle 13 is limited by the limit disc 18. Then, push the handle 13 backward to drive the turntable 12 to rotate through the square rod 16. The rotation angle of the turntable 12 can be limited by the sliding of the limit rod 14 in the limit groove 15. The turntable 12 drives the valve plate 21 to rotate through the rotating rod 2, and the valve plate 21 drives the sealing plate 24 to rotate through the connecting rod 23, so that the two groups of sealing plates 24 are misaligned with the water inlet and outlet of the valve body 1, and then the valve body 1 can be quickly opened. At this time, the bolt 19 aligns with the first jack 111 as the handle 13 rotates. When the handle 13 is released, the spring 17 uses its own resilience to drive the bolt 19 to insert into the first jack 111 through the handle 13, thereby completing the position fixation of the valve plate 21 and the sealing plate 24.
