Wet spray eqnipment is automatic sprinkler system detects system features a simple and practical testing device. In the wet, preaction systems are called partition network terminal or system network terminal settings. Eqnipment General connection pipe, pressure gauge, control valves and pipes, conditional or remote pressure and flow measurement device and solenoid valve. General requirements for installation is simple, reliable measurement results.
1. fire water tank; 2. inlet elbow 1.2m×1.2m square anti Vortex Board, pool bottom distance suction pipe diameter 1.5 times, but a minimum 152mm; 3. suction pipe; 4. Frost cover; 5. eliminate the stress of flexible connection pipe; 6. gate valve; 7. eccentric reducer joints; 8. suction pressure gauge; 9. horizontal pump body can open fire pump; 10-automatic exhaust; 11-outlet pressure gauge; 12. reductive of outlet tee; 13. outlet check valve; 14. pressure valve; 15. outlet; 16. spherical valves or dripping water; 17. hose valve hose valves collection tube; 18. pipe support; 19. indicative gate or indicative butterfly valve.
Alarm set location, close to the alarm valve, make it easy to hear the ring tone. Distance alarm 3m, hydraulic pressure at the alarm injector .05mpa, its alarm intensity should be not less than 70dB.
On dry alarm valve group installation site requirements. Dry alarm valve group is dry sprinkler fire extinguishing system, the main component, dry extinguishing system applicable ambient temperature is below 4 ° c and above 70 ° c, low temperature, the system uses the site likely frozen, dry alarm valve groupShould be installed in a place without freezing. Mainly because of the dry alarm valve group is servo, water side of the pipeline is filled with water, dry valve system side-air Chamber, in order to ensure their tightness generally filled with the design requirements of seal water. If dry valve installation place frozen, dry valve water frozen parts may occur, especially in dry valve Chamber side of seal water more prone to freezing, the influence of light by opening of the valve, serious it may make dry valve is compromised.
