Days of wide fire monitor fixed fire water cannons fire water cannons fire artillery fire fighting is an important long-range fire-fighting equipment, fire water cannons (PS). Fire water cannons are spraying water, long-distance fire fighting equipment in general solid substances. Gun fire from the base, into the water, rotors, lodgement, jet adjustment ring, handle and locking mechanism and other components can be used for horizontal rotary barrel rotation and pitch, and to achieve positioning. Gun wide pressure range, long range and can perform DC up to 90 ° blossom, spray jet stepless adjustment. Its light weight, small size, full-featured, good fire effect, is the most important feature specification model gun flow (L / S) range (M) Working Pressure (Mpa) Weight (Kg) connecting flange PS20 20 ≥48 0.8-1.0 ≤35 DN80PS25 25 ≥50 PS30 30 ≥55 0.5-1.2 ≤38 DN80PS40 40 ≥60 PS50 50 ≥65 PS60 60 ≥70 0.9-1.2 ≤45 DN100PS70 70 ≥75 PS80 80 ≥80 Hong Anguo standard fire hydrant fire hydrant SN65 \ 50 type indoor fire water supply pipe network to interface with the valve, factory, warehouse, high-rise buildings, public buildings and ships and other indoor fixed fire-fighting facilities, fire extinguishers, usually installed in the hydrant box, with fire hoses and nozzles, etc. supporting the use of equipment. Fire hydrant, is an important part of fire water system, which is installed in the indoor fire box, usually nominal diameter (mm): DN50, DN65 are two, nominal working pressure 1.6MPa, strength test pressure 2.4MPa, use dry powder fire extinguisher for medium: Clean quality water, foam mixture. Fire hydrant generally be divided into ordinary type, vacuum regulator type, rotary type, etc., fire extinguisher validity fire way of doing it is connected to the water with a bolt opening fire, in addition there is the fire hydrant hydrant box button, press this button remote Start the fire pump to supply water hydrant. Fire extinguishers, ultra-fire extinguishers validity provided by the Dongguan City, South City Super Fire Department equipment operators. Fire extinguishers, ultra-fire extinguishers valid Dongguan Nancheng Super Fire Department equipment operators (www.jyfire.com) this year introduced a new upgrade, the above picture is for reference only, please call the contact phone book pages or pictures on request The latest information, contact: Lishao Ji.
