Description

Technical Field

[0001] This utility model relates to the field of smoke exhaust valve technology, and in particular to a smoke exhaust valve. Background Technology

[0002] A smoke exhaust valve is a valve installed at the end of each branch pipe of a mechanical smoke exhaust system. It is normally closed and meets the air leakage requirements. It is opened manually or electrically in case of fire or when smoke exhaust is required, and serves the function of smoke exhaust.

[0003] Existing smoke exhaust valves typically use bolted connections during installation. While this improves the stability of the connection, it requires external tools for disassembly and installation. Furthermore, if there are many connecting bolts, the operation can be time-consuming and labor-intensive. Therefore, a new type of mounting base structure is needed to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a smoke exhaust valve to solve the problem mentioned in the background art, where existing smoke exhaust valves usually adopt a bolt connection structure during installation. Although this improves the stability of the connection, external tools are required for disassembly and installation, and if there are many connecting bolts, it will lead to time-consuming and labor-intensive operation.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a smoke exhaust valve, comprising:

[0007] The mounting assembly includes a valve body, a plug, a receiving plate, and a concave base. One end of the valve body is fixedly connected to the plug, the top of the receiving plate is fixedly connected to the concave base, the plug movably inserts into the concave base, and the bottom end of the receiving plate is fixedly welded to an external device.

[0008] A quick-installation component includes a rectangular placement slot, a first spring, a locking block, and a locking groove. The insertion block has rectangular placement slots at both ends. One end of the first spring is fixedly connected to the inner end of the rectangular placement slot, and the locking block is fixedly connected to the other end of the first spring. The concave base has locking grooves through both ends, and the locking block is movably connected in the locking groove.

[0009] Furthermore, the card block is shaped like a right-angled trapezoid.

[0010] Furthermore, it also includes a convenient disassembly assembly, which includes an L-shaped support plate, a receiving groove, and a rectangular top rod. The L-shaped support plate is fixedly connected to both sides of the concave base, and a receiving groove is formed through the L-shaped support plate. The rectangular top rod is movably connected in the receiving groove.

[0011] Furthermore, the easy-to-disassemble assembly also includes a pressure plate, one side of which is movably connected to the L-shaped support plate, and a rectangular top rod is fixedly connected to the side of the pressure plate.

[0012] Furthermore, the easy-to-disassemble assembly also includes a circular groove, a cylindrical rod, and a second spring. The pressure plate has circular grooves extending through both ends. The cylindrical rod is fixedly connected to both sides of the L-shaped support plate. The cylindrical rod is movably connected in the circular groove. The second spring is movably connected to the outer ring of the cylindrical rod.

[0013] Furthermore, the easy-to-disassemble component also includes a limiting ring, one end of which is fixedly connected to the limiting ring, and the diameter of the limiting ring is larger than the diameter of the circular groove.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] This invention involves contacting the inclined surface of the locking block with the concave base, and then pressing down on the valve body. At this time, the locking block transmits the external force to the first spring. Under the action of the inclined surface, the locking block gradually moves into the rectangular placement groove. Then, the insert block is inserted into the concave base, and the first spring pushes the locking block into the groove. This enables convenient positioning and installation of the valve body, and the friction between the insert block and the concave base prevents the installed valve body from shifting.

[0016] Based on the aforementioned beneficial effects, by pressing the pressure plates on both sides, the rectangular top rod will move towards the locking block until the locking block is pushed into the rectangular placement slot. Then, the valve body is pulled upwards, and the insert block is removed from the concave base, thereby realizing the quick disassembly of the valve body, which facilitates the maintenance and replacement of the valve body.

[0035] Card block 203 is shaped like a right trapezoid.

[0036] The shape of the card block 203 ensures its smooth downward movement.

[0037] It also includes a convenient disassembly component, which includes an L-shaped support plate 301, a receiving groove 302 and a rectangular top rod 303. The L-shaped support plate 301 is fixedly connected to both sides of the concave base 104. The receiving groove 302 is opened through the L-shaped support plate 301, and the rectangular top rod 303 is movably connected in the receiving groove 302.

[0038] The L-shaped support plate 301 provides a guarantee for the opening of the receiving groove 302, and the receiving groove 302 provides a guarantee for the receiving and movement of the rectangular top rod 303.

[0039] The easy-to-disassemble components also include a pressure plate 304, an L-shaped support plate 301 is movably connected to the pressure plate 304 on one side, and a rectangular top rod 303 is fixedly connected to the side of the pressure plate 304;

[0045] Working principle: First, the receiving plate 103 is welded to the external equipment. The insert block 102 installed at the bottom of the valve body 101 is inserted into the concave base 104. At this time, the inclined surface of the bottom of the locking block 203 will contact the inner walls on both sides of the concave base 104. During continuous pressing, the locking block 203 will move into the rectangular placement groove 201 with the cooperation of the first spring 202. During continued pressing, when the locking block 203 moves to the position of the slot 204, the squeezing force on the first spring 202 disappears. At this time, the first spring 202 pushes the locking block 203 into the slot 204, realizing the valve... When the valve body 101 needs to be disassembled, press the pressure plates 304 at both ends inward. At this time, the rectangular top rod 303 moves at the receiving groove 302, and the second spring 307 is compressed until the locking block 203 is pushed from the locking groove 204 into the rectangular placement groove 201. Then, move the valve body 101 outward, and the insert block 102 is taken out from the concave base 104. Then, release the pressure plate 304, and the second spring 307 returns to its original position, pushing the pressure plate 304 together with the rectangular top rod 303 back to its original position. This step can realize convenient positioning and installation of the valve body 101 and quick disassembly.
