The invention provides a manufacturing process for a fire protection regulating valve. The manufacturing process for the fire protection regulating valve is characterized in that the fire protection regulating valve comprises a valve body, a temperature sensor, a torsion spring, blades and a blade linkage support. An electrical signal linkage device is arranged on the left side of the valve body. The temperature sensor and an automatic closing device are arranged on the right side of the valve body. The electrical signal linkage device, the temperature sensor and the automatic closing device are electrically connected, and are all fixedly connected to the valve body. The three blades are arranged inside the valve body. The two ends of each blade are connected with the inner wall of the valve body through a shaft. The torsion spring is arranged in the middle of the inner wall of the left side of the valve body. The torsion spring is connected with one end of the middle blade inside the valve body, and is electrically connected with the automatic closing device. The blade linkage support is arranged inside the valve body, and is connected with the three blades. A reset handle is arranged at the top of the outer wall of the valve body, and is connected with the blade linkage support. The manufacturing process for the fire protection regulating valve effective prevents the fire behavior and smoke from spreading along air pipes.
Description
technical field [0001] The invention belongs to the field of air-conditioning and ventilating equipment, and in particular relates to a manufacturing process of a fire-proof regulating valve. Background technique [0002] In modern buildings, ventilation facilities are essential. Since the air duct is an important part of building ventilation equipment, it connects the various rooms of the building. When a fire breaks out, a large amount of dense smoke will gather inside the building. When the temperature in the air duct exceeds 70°C, the fire control valve installed in the air duct The temperature sensor outputs the signal to the control center, and the control center outputs the electric signal to the automatic closing device and the electric signal linkage device, so that the blades are automatically closed, which basically meets the fire resistance stability and fire resistance requirements. However, due to the use of electrical signal transmission, the fire control val...
