Description

Technical Field

[0001] This utility model belongs to the field of air valve technology, and more specifically, it relates to a PP flame-retardant electric air valve. Background Technology

[0002] In the event of a fire, the flame-retardant air valve can automatically close, blocking the airflow channels and preventing flames and high-temperature smoke from spreading to other areas through the ventilation ducts, thereby controlling the fire's extent and buying time for personnel evacuation and fire rescue.

[0003] However, existing dampers only block flames and high-temperature smoke, and cannot extinguish flames. The continuous high temperature of the flames can damage the dampers, limiting their practical application. Therefore, this paper studies and improves upon existing structures and shortcomings to provide a PP flame-retardant electric damper, aiming to achieve greater practical value. Utility Model Content

[0021] Example:

[0022] As attached Figure 1 To be continued Figure 4 As shown: This utility model provides a PP flame-retardant electric air valve, including a main housing 1 made of PP material. A mounting base 4 is connected to the outer side of the main housing 1. A gas storage tank 5 containing heptafluoropropane is fixedly installed on the top side of the mounting base 4 by fasteners. The main housing 1 has a through hole. A connecting pipe 6 is fixedly installed on the inner side of the through hole. The bottom end of the connecting pipe 6 is located inside the main housing 1, and one end of the top side of the connecting pipe 6 is connected to the output end of the gas storage tank 5. A valve shaft 2 is rotatably connected to the inner side of the main housing 1, and a valve plate 3 is fixedly installed on the outer side of the valve shaft 2.

[0023] A geared motor 7 is fixedly installed on the outer side of the main housing 1. One end of the valve shaft 2 passes through the main housing 1 and is fixedly connected to the output end of the geared motor 7, which can realize the automatic rotation of the valve shaft 2 to automatically adjust the valve plate 3.

[0024] The mounting base 4 has clamping plates 9 installed on both sides. Two sets of light rods 8 are symmetrically slidably connected to the clamping plates 9. One end of each light rod 8 is fixedly connected to one side of the mounting base 4, which allows the clamping plates 9 to move flexibly.

[0025] Limiting blocks 10 are fixedly installed on the other end of each of the light rods 8 to prevent the clamping plate 9 from falling off the light rod 8.

[0026] The mounting base 4 is rotatably connected to a bidirectional screw 11. The outer ends of the bidirectional screw 11 are threaded to the inner sides of the two sets of clamping plates 9, respectively, which can drive the clamping plates 9 to move and achieve self-locking. A crank handle 12 is fixedly installed on one end of the bidirectional screw 11, which can drive the bidirectional screw 11 to rotate flexibly.

[0027] A solenoid valve 13 is fixedly installed in the middle of the connecting pipe 6, which can enable flexible control of the gas storage tank 5.

[0028] The main housing 1 has a through hole 2, in which a temperature sensor 14 is installed. The top of the temperature sensor 14 passes through the through hole 2 and is fixedly connected to the bottom side of the mounting base 4. A controller is fixedly installed on one side of the mounting base 4. The controller is connected to the temperature sensor 14 and the solenoid valve 13 through wires to realize real-time temperature monitoring so that the solenoid valve 13 will be automatically opened after the set threshold temperature is reached to release the gas inside the gas storage tank 5.

[0029] The working principle of this embodiment is as follows: When the electric air valve is needed, first place the mounting base 4 on the outside of the main housing 1, turn the crank handle 12 to drive the bidirectional screw 11 to rotate, and the bidirectional screw 11 drives the clamping plate 9 to tighten the main housing 1. Connect the electrical components such as the geared motor 7, solenoid valve 13, and temperature sensor 14 to the power supply and control unit. Connect the output end of the gas storage tank 5 to the connecting pipe 6. When a flame appears in the main housing 1, the temperature sensor 14 detects the high temperature, and the geared motor 7 drives the valve shaft 2 and valve plate 3 to rotate to block the flame. At the same time, the solenoid valve 13 opens, and the heptafluoropropane stored in the gas storage tank 5 enters the connecting pipe 6 and is injected into the main housing 1 to extinguish the flame and cool the main housing 1, preventing damage to the main housing 1.

[0030] Finally, it should be noted that the gas storage tank 5 is an existing device or equipment, or a device or equipment that can be implemented with existing technology. Its power supply, specific composition and principle are clear to those skilled in the art and are common knowledge in the field, so they will not be described in detail.
