Selector Valve for Fire Fighting Fire Suppression System Accessories

Selector valve of fire suppression system
1 Purpose :
For combined distribution system, header pipe are connected at one end, and other end with protection area network connection, normally closed, pneumatic or manual way to open it. System starts up, driven by electromagnetic device releases starting order to open the gas to the fire protection zone corresponding to choose container valve valve and fire extinguishing agent storage device, to release agent into the implementation of fireprotection.
2 Structure:
by the valve, piston, cylinder, inward and outward pressure arm, jib, drive union or connecting flange and so on,has the advantages of simple structure, convenient operation and reliable characteristics

4Installation instructions:
1) the operating handle shall be installed at the side of the surface operation, when installing height more than 1.7m measures should be taken to facilitate operation. Should have corresponding protection zone protection objectname or number of permanent marks. 2) need to be manually opened the selector valve, open revolving arm whilepull pressure arm
5 Maintenance instructions:
appearance inspection should be monthly, no collision deformation and mechanical damage, surface rust,derrick and pressure arm flexible rotation without binding may continue to use.
6 Note: after installation should check whether the pressure arm is pressure, there is no loose phenomenon. Regular checks should be put into use after turning arm can normal rotation, whether normal pressure arm is raised, found a binding should be dealt with immediately.
