Ordinary switch type electric fire gate valve

1Ordinary switch type electric fire gate valveBriefly describe

Fire gate valve is an industrial product. The opening and closing component of the fire gate valve is the gate plate, and the movement direction of the gate plate is perpendicular to the fluid direction. The gate valve can only be fully opened and fully closed It cannot be adjusted or throttled. The gate valve has two sealing surfaces, and the two sealing surfaces of the commonly used mode gate valve form a wedge shape. The wedge angle varies with the valve parameters, usually 50 degrees, and 2 ° 52 'when the medium temperature is not high. The gate of a wedge gate valve can be made as a whole, called a rigid gate; It can also be made into a gate that can produce slight deformation to improve its processability and compensate for the deviation of the sealing surface angle during the processing. This type of gate is called an elastic gate.

Types of fire gate valves According to the sealing surface configuration, wedge gate valves can be divided into wedge gate valves and parallel gate valves. Wedge gate valves can also be divided into single gate, double gate, and elastic gate valves; Parallel gate valves can be divided into single gate plate and double gate plate. According to the thread position of the valve stem, it can be divided into two types: rising stem gate valves and hidden stem gate valves.

IIOrdinary switch type electric fire gate valveMaintenance and troubleshooting

Quarterly inspection:

manual/Electric switching test, lubricating grease injection (lithium based grease, replaced annually).

Sealing surface leakage detection (pressure gauge pressure drop method).

Common faults:

Valve blockage: blockage caused by impurities in the pipelineInstall a Y-shaped filter.

Overload of actuator: torque set too lowRe calibrate the overload protection value.

Signal loss: Check the grounding of the circuit and eliminate electromagnetic interference.

IIIOrdinary switch type fire protectionelectricgate valveComparative advantages with traditional valves

Response speed: Electric control can be used inWithin 30 seconds, the manual valve needs personnel to arrive at the site.

System Integration: Support andBIM system and intelligent fire protection platform data exchange to achieve remote monitoring.

Safety: In emergency situations, the smoke exhaust system can be linked to close the valve first and then extinguish the fire to prevent the spread of the fire.

summary

Electric fire gate valve is the core component of fire automation, and its selection requires comprehensive system pressure, medium, control mode, and certification requirements. Under the trend of smart fire protection, valves with high integration and IoT functionality (such as support for...)LoRa wireless communication will become mainstream, further enhancing disaster response efficiency.
