Description

Technical Field

[0001] This utility model relates to the technical field of fireproof valve components, and in particular to a smoke exhaust fireproof reinforced valve frame for air conditioning systems. Background Technology

[0002] Fire dampers are critical fire-fighting devices used in building ventilation and air conditioning systems. They are typically installed in ventilation ducts and are used to automatically or manually close the valve in the event of a fire, preventing the spread of flames and high-temperature smoke along the duct and effectively protecting personnel and the building structure. Existing fire dampers are generally housed in a metal frame, which is connected to the ventilation system via ductwork. The valve's opening and closing is driven and regulated by an electronic control panel. A typical structure involves the valve body fixed within a rectangular or circular metal frame, with the electronic control panel mounted on the outer wall or internal support of the frame. A motor or actuator drives the valve disc to rotate.

[0003] However, because the piping containing the fire damper heats up significantly during fires or prolonged operation, the frame itself, as a metal heat conductor, rapidly transfers heat to the area where the electronic control board is installed. Existing structures generally lack effective heat dissipation designs, causing the electronic control board to be prone to electronic component aging, performance drift, or even failure under high-temperature environments. Once the electronic control board malfunctions, the valve plate may not be able to close or open accurately or in a timely manner, directly affecting the reliability of the fire damper's operation in emergency situations. Even more seriously, some... Utility Model Content

[0004] The technical problem this utility model aims to solve is that the existing structure's electrical control board is arranged close to the frame, which easily causes heat to accumulate, resulting in excessively high internal temperature of the pipe, accelerating the occurrence of malfunctions, and posing potential hazards to subsequent fire safety management and maintenance.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a smoke exhaust and fireproof reinforced valve frame for an air conditioning system, including a compartment body. An electric control board is fixedly installed on one side of the compartment body, and the electric control board is electrically connected to a smoke exhaust and fireproof valve located on the inner wall of the compartment body. A pair of sliding seats are fixedly installed at the top and bottom of the compartment body, and a heat collection plate is slidably installed between the sliding seats. A side handle is detachably installed on one side of the heat collection plate. A connecting plate is fastened to the heat collection plate by mounting bolts, and two cooling fans are fixedly installed on the connecting plate. An injection groove is opened at the top of both the connecting plate and the heat collection plate, and a cavity located inside the heat collection plate is connected below the injection groove. The bottom of the cavity is set as a mesh plate.

[0006] As a further improvement of this utility model, a sliding groove is provided on the inner side of the sliding seat, and rib frames that are slidably connected to the sliding groove are fixedly provided on both sides of the heat collection plate.

[0007] As a further improvement of this utility model, the heat collection plate is configured as a copper plate structure, and a combined sleeve is fixedly provided on the outside, and the combined sleeve is fastened to the side handle by combined bolts.

[0008] As a further improvement of this utility model, the outer sleeve of the side handle is made of rubber anti-scalding sleeve, and two sliding plugs are fixedly provided on the other side.

[0009] As a further improvement of this utility model, the mesh plate has a plurality of mesh holes for silicone grease to pass through, and the mesh hole diameter is set to 0.18-0.25cm.

[0010] As a further improvement of this utility model, a reinforcing side plate is fixedly provided on the outer side of the silo body, and reinforcing bolts are threadedly connected at the four corners of the reinforcing side plate.

[0011] The beneficial effects of this utility model are as follows: By adding sliding seats at the top and bottom of the chamber, the heat collection plate can be easily inserted and removed. Combined with the fastening design of the side handle and the combined sleeve, it not only improves the convenience of heat collection plate replacement and maintenance, but also avoids safety hazards during operation through the anti-scalding sleeve. The heat collection plate adopts a copper plate structure, combined with an internal injection groove and mesh plate, which can be filled with silicone grease and form a highly efficient heat conduction channel. With the cooperation of the cooling fan, it can quickly remove the heat accumulated inside the chamber, thereby reducing the ambient temperature around the electronic control board, effectively delaying the aging of components, ensuring the stable operation of the electronic control board, and ensuring that the electronic control board on one side of the chamber is always in a suitable working environment.

A pair of sliding seats 3 are fixedly installed at the top and bottom of the chamber 1, respectively, and a heat collection plate 4 is slidably installed between the sliding seats 3. A sliding groove is opened on the inner side of the sliding seat 3, and rib frames 8 are fixedly installed on both sides of the heat collection plate 4, which are slidably connected to the sliding groove; this facilitates the sliding insertion of the heat collection plate 4. A side handle 5 is detachably installed on one side of the heat collection plate 4. The heat collection plate 4 is made of copper plate structure, and a combined sleeve 9 is fixedly installed on the outer side, and the combined sleeve 9 is fastened to the side handle 5 by combined bolts. The outer side of the side handle 5 is covered with a rubber anti-scalding sleeve to avoid burns from residual heat during disassembly. Two sliding rods 10 are fixedly installed on the other side.

[0022] As attached Figure 1 , 2 As shown, the heat collector plate 4 is fastened to the connecting plate 6 by mounting bolts, and the connecting plate 6 is fixedly equipped with two cooling fans. Both the connecting plate 6 and the top of the heat collector plate 4 have injection grooves 7, and the injection grooves 7 are connected to a cavity located inside the heat collector plate 4.

[0023] Working Principle: In this invention, an electrical control board 2 is fixedly installed inside the chamber 1. The electrical control board 2 is electrically connected to the smoke exhaust and fire damper on the inner wall of the chamber 1 to control the opening and closing of the valve. To prevent the electrical control board 2 from failing due to overheating when the pipeline heats up, sliding seats 3 are respectively provided at the top and bottom of the chamber 1. The sliding seats 3 have internal grooves, and the rib frame 8 slides in the grooves, allowing the heat collection plate 4 to be smoothly pushed in or pulled out on the sliding seats 3. The heat collection plate 4 is made of copper plate with excellent thermal conductivity. One side of it is detachably connected to the side handle 5 through a combined sleeve 9. The outside of the side handle 5 is covered with a rubber anti-scalding sleeve to prevent residual high temperature from causing burns to the operator during manual disassembly.

[0024] A connecting plate 6 is securely mounted on the heat collection plate 4.
