Technical Field

[0001] The utility model relates to the technical field of fireproof valves, in particular to a plate-type fireproof valve. Background Art

[0002] A fireproof valve is a fire-fighting component installed on the pipeline of a mechanical smoke exhaust system. When a fire occurs, it opens for smoke exhaust. When the temperature of the smoke inside the smoke exhaust pipeline is relatively high, the baffle is rotated manually by a rotating disk, and the clamping rod is pushed into the clamping hole by the first spring, thereby closing the valve, which can play a role in isolating smoke and fire.

When a fire occurs, the smoke exhaust is turned on. When the temperature of the smoke in the smoke exhaust pipe is relatively high, manually drive the baffle 3 to rotate through the rotating disk 4, and squeeze the positioning rod 6 into the positioning hole 10 through the first spring 7, thereby closing the valve, so as to play a role in isolating smoke and fire.

[0028] Refer to Figure 2 and Figure 3, the connecting device 8 includes a rectangular strip 804. A first connecting groove 801 is formed at the top of the baffle 3. A rotating plate 802 is fixedly connected to the surface of the rotating rod 2 close to the valve body 1. The rotating plate 802 is slidably connected to the inner wall of the first connecting groove 801. A rectangular groove 803 is formed in the inner wall of the first connecting groove 801. The inner wall of the rectangular groove 803 is slidably connected to the rectangular strip 804. A fixing groove 805 is formed on one side of the rotating plate 802. The inner wall of the fixing groove 805 is slidably connected to the rectangular strip 804. When using the connecting device 8, manually slide the rotating plate 802 into the first connecting groove 801, and then slide the rectangular strip 804 from the inner wall of the rectangular groove 803 into the fixing groove 805, so that the rotating plate 802 can be well fixed inside the first connecting groove 801. Reverse operation can move the rotating plate 802 away from the inside of the first connecting groove 801, which is convenient for replacing the baffle 3. One side of the inner wall of the rectangular groove 803 is fixedly connected to a damping rod 807.

One end of the sliding strip 810 is fixedly connected to one side of the rectangular strip 804 close to the damping rod 807. Manually control the sliding of the sliding strip 810 on the inner wall of the sliding groove 809, and then the sliding of the rectangular strip 804 on the inner wall of the rectangular groove 803 can be well controlled.

[0029] Refer to Figure 4, the fixing device 9 includes a connecting sleeve 902. An opening 901 is provided at the top of the valve body 1. The bottom of the valve body 1 is slidably connected to the connecting sleeve 902. When using the fixing device 9, manually sleeved the connecting sleeve 902 on the bottom of the valve body 1, so as to block the opening 901. Reverse operation can expose the opening 901, which is convenient for replacing the baffle 3 through the opening 901, and thus there is no need to disassemble the valve as a whole. A limiting groove 904 is provided on the surface of the valve body 1. A rubber frame 903 is arranged on the inner wall of the limiting groove 904. The rubber frame 903 is fixedly connected to the inner wall of the connecting sleeve 902. When the connecting sleeve 902 is sleeved on the bottom of the valve body 1, the rubber frame 903 is arranged inside the limiting groove 904. Since the valve is made of refractory material, the heat insulation effect is relatively good, so that the rubber frame 903 will not be melted, which can play a certain sealing effect. One side of the connecting sleeve 902 is fixedly connected with a first rectangular plate 905. A second rectangular plate 906 is arranged on the top of the connecting sleeve 902. One side of the second rectangular plate 906 is fixedly connected with one side of the valve body 1. A second connecting groove 907 is provided at the bottom of the first rectangular plate 905. A slider 908 is slidably connected to the inner wall of the second connecting groove 907. The bottom of the slider 908 is fixedly connected with a rectangular frame 909. The rectangular frame 909 is sleeved on the surfaces of the first rectangular plate 905 and the second rectangular plate 906. The length of the second rectangular plate 906 is shorter than that of the first rectangular plate 905. When the connecting sleeve 902 is sleeved on the bottom of the valve body 1, the first rectangular plate 905 and the second rectangular plate 906 are arranged together. Control the slider 908 to slide on the inner wall of the second connecting groove 907, so as to sleeve the rectangular frame 909 on the surfaces of the first rectangular plate 905 and the second rectangular plate 906, which can well limit the connecting sleeve 902 at the bottom of the valve body 1. One side of the inner wall of the second connecting groove 907 is fixedly connected with a third spring 910. One end of the third spring 910 close to the second connecting groove 907 is fixedly connected with one side of the slider 908. By squeezing the slider 908 in the direction close to the second connecting groove 907 through the third spring 910, the rectangular frame 909 can be well limited on the surfaces of the first rectangular plate 905 and the second rectangular plate 906. A notch 911 is provided on one side of the rectangular frame 909. A rubber block 912 is arranged on the inner wall of the notch 911. The rubber block 912 is fixedly connected with one side of the first rectangular plate 905. Squeeze the rubber block 912 into the notch 911, so that the rectangular frame 909 can be well limited on the surface of the first rectangular plate 905.

[0030] Working principle: When a fire occurs, the smoke exhaust is turned on. When the temperature of the smoke inside the smoke exhaust pipe is relatively high, manually rotate the rotating disk 4 to drive the baffle 3 to rotate, and squeeze the positioning rod 6 into the positioning hole 10 through the first spring 7, thereby closing the valve, which can play a role in blocking smoke and fire. When using the connecting device 8, manually slide the rotating plate 802 into the first connecting groove 801, and then slide the rectangular strip 804 from the inner wall of the rectangular groove 803 into the fixing groove 805, and slide it away from the rectangular groove 803 through the second spring 808, thereby restricting the rectangular strip 804 well inside the fixing groove 805, so that the rotating plate 802 can be well fixed inside the first connecting groove 801. Manually control the sliding of the sliding strip 810 on the inner wall of the sliding groove 809, and then the sliding of the rectangular strip 804 on the inner wall of the rectangular groove 803 can be well controlled, so that the rectangular strip 804 can be far away from the rectangular groove 803, and the rotating plate 802 can be far away from the inside of the first connecting groove 801, which is convenient for replacing the baffle 3, and thus extends the service life of the valve to a certain extent. When using the fixing device 9, manually sleeve the connecting sleeve 902 on the bottom of the valve body 1, thereby blocking the opening 901. When the connecting sleeve 902 is sleeved on the bottom of the valve body 1, the rubber frame 903 is arranged inside the limiting groove 904. Because the valve is made of fire-resistant material, the heat insulation effect is relatively good, so that the rubber frame 903 will not be melted, which can play a certain sealing effect. When the connecting sleeve 902 is sleeved on the bottom of the valve body 1, the first rectangular plate 905 and the second rectangular plate 906 are arranged together. Control the sliding of the slider 908 on the inner wall of the second connecting groove 907, and then sleeve the rectangular frame 909 on the surfaces of the first rectangular plate 905 and the second rectangular plate 906, and squeeze the slider 908 towards the second connecting groove 907 through the third spring 910, thereby restricting the rectangular frame 909 well on the surfaces of the first rectangular plate 905 and the second rectangular plate 906. At the same time, the rubber block 912 is squeezed into the notch 911, so that the rectangular frame 909 can be well restricted on the surface of the first rectangular plate 905, so that the connecting sleeve 902 can be well restricted on the bottom of the valve body 1. Reverse operation can expose the opening 901, which is convenient for replacing the baffle 3 through the opening 901, and thus there is no need to disassemble the valve as a whole.
