Description

Fire control is with disjunctor preaction valve

Technical Field

The utility model particularly relates to a conjoined pre-acting valve for fire fighting.

Background

The pre-action system combines the automatic fire detecting and alarming technology with the automatic water spraying and fire extinguishing system, and a closed type sprinkling nozzle is installed in the system. The system is characterized by a dry system because the system is usually filled with low-pressure air or nitrogen for monitoring when a fire is not occurring. It is therefore suitable for installation in places where water is required to extinguish a fire but where it is absolutely not permissible to bubble water in a fire. The pre-acting valve on the market at present usually comprises a one-way valve and a rain valve which are separated, the joint strength of the two valves is crossed, the two valves cannot be connected with larger pressure, and the pre-acting valve is very inconvenient to transport and install when entering a field.
