Problems solved by technology

Although the traditional fire damper has the function of preventing fire, it cannot adjust the fresh air and the air supply of the air conditioner according to the needs of the indoor environment.
In addition, after the traditional fire damper is installed, it is necessary to install additional regulating valves for fresh air and air-conditioning air supply. After the two are superimposed, the installation volume increases, the space occupied is too large, the manufacturing cost increases, and it is not easy to install.
Secondly, the existing fire dampers are not sensitive enough to the fire protection temperature, and the fire protection action time is too long, which cannot meet the new requirements of customers

Embodiment Construction

[0014] like figure 1 As shown, a double valve for fire protection, including a fresh air regulating valve and an air conditioning regulating valve, is installed in the tee 1 connected with the main pipe in the fresh air pipe and the air regulating pipe. Both the fresh air control valve and the air conditioner control valve include a motor 5, a screw rod 6, a guide sleeve 7, a valve plate 8, a temperature sensor 3, and a control panel 4. The motor 5 is fixedly installed in the pipeline, and its output shaft is equipped with a screw rod 6. The screw rod 6 is installed inside the guide sleeve 7 and is connected with the guide sleeve 7 in a spiral pair. The valve plate 8 of ring, sealing ring and valve plate 8 all adopt fireproof material to make. A travel rod is installed on the guide sleeve 7, and two travel switches 2 matched with the travel rod are arranged above the guide sleeve 7.

Abstract

The invention relates to ventilating fireproof equipment, in particular to a fireproof dual valve. The fireproof dual valve is formed by motors, threaded rods, guide sleeves, valve plates and temperature sensors. Each threaded rod is installed on an output shaft of the corresponding motor, the threaded rods are installed inside the guide sleeves and spirally and movably connected with the guide sleeves, and the end of each guide sleeve is provided with the corresponding valve plate with sealing rings. The fireproof dual valve has the functions of ventilation, fire prevention, fresh air volume adjustment and air conditioner air regulation, and has the advantages of being complete in function, small in size and high in intelligentization degree.

Description

technical field [0001] The invention relates to a fire prevention device, in particular to a ventilation fire damper. Background technique [0002] In air-conditioning air supply or fresh air ventilation ducts, fire dampers are usually installed for fire prevention. Although the traditional fire damper has the function of preventing fire, it cannot adjust the fresh air and the air supply of the air conditioner according to the needs of the indoor environment. In addition, after the traditional fire damper is installed, it is necessary to install additional regulating valves for fresh air and air-conditioning air supply. The superposition of the two increases the installation volume, takes up too much space, increases the manufacturing cost, and is not easy to install. Secondly, the existing fire dampers are not sensitive enough to the fire protection temperature, and the fire protection action time is too long, which cannot meet the new requirements of customers.
