Many buildings are designed with fire dampers to ensure the safety of the design. Since valve manufacturers have to have corresponding effective methods in valve design and installation, only reasonable application design can allow them to give full play to their application effects. As the corrosion-resistant solenoid valve is installed, corresponding space needs to be reserved according to the later use and maintenance. Generally, the space is about 20cm, which is a hard standard requirement. Because the performance characteristics of the flame retardant valve are very obvious, it is a very popular product.

Fire damper has three outstanding advantages in building design:

The transmission of the actuator is flexible. Good gas tightness

Second, the electric start consumes little current.

Strong corrosion resistance and long service life.

When using a fire damper, certain conditions must be met, such as the temperature and humidity of the environment in which it is used. Only in this way can the fire be controlled. The electric signal can be set during installation, the fan can be linked, the operation is safe and reliable, and the solenoid valve of the water purifier is powerful.

The device is usually installed in the central air-conditioning duct system, and very precise temperature control can be obtained through the installation of valves, and gravity can be used. This is a high-performance gravity and spring mechanical action. The classification of diaphragm solenoid valves is very different. Different types have different functions and performances. When choosing, we have to choose the required model according to our needs.

The smoke control valve is composed of two separable actuators and a regulating valve part. The upper part is an actuator, which receives the output signal of 0~10mADC or 4~20mADC and converts it into the corresponding linear displacement to drive the lower part of the regulating valve. Action, directly adjust the flow of fluid. At present, the actuators of various fire dampers produced by valve manufacturers are basically the same, but due to the different conditions of use, the fire dampers (adjustment mechanism) have various structures. The most commonly used are straight-through single valve seat and straight-through double valve seat.
