The products are summed up:
ZSFM series lack of mutual understanding rainforest by main valve , water conservancy alarm bell , pressure switch , manual ball valve , electromagnetic valve , three direct links ball valve valve, needle valve and controlling the pipeline ,etc. make up . Mix shower nozzle , water curtain shower nozzle of making etc. with , person who close shower nozzle and fire warning control system can make up corresponding water spray the fire extinguishing system. It is of simple structure , operate and easy , safe and reliable, install and safeguard conveniently when the characteristic. While catching fire, drenched with rain the valve and opened, the system starting type shower nozzle sprays water and puts out a fire automatically in unison, not only can put out the fire in the place fire source but also can spray water automatically to the whole area protected at the same time , thus prevent fire from spreading and enlargement . It is easy to be suitable for the frozen building and place with dangerous and large fire needing to lay special stress on protecting. |

The structure and use:
The main valve of rainforest valve of the ZSFM series lack of mutual understanding adopts diaphragms and divides the main valve into upper and lower two, have it in order to control. Utilize of bad to produce water pressure strength realize main valve seal area from head to foot. When not catching fire , the ball valve handle of three direct links is downward, needle valve , overhauling the ball valve, the end ball valve, in order to open the state , the electromagnetic valve , manual ball valve , discharging the ball valve in order to hold the state of closing, manometer 1 is the inlet pressure , manometer 2 is 0. The main valve, in order to close the state at this moment. While catching fire , three kinds of control methods control the main valve to open and put out a fire . After the main valve is opened, the pressure enters the pressure switch and water conservancy alarm bell to give out alert sound; The pressure switch sends out the signal or turns on the fire control pump to the control centre. Lack of mutual understanding rainforest valve is it defend structure of restoring to the throne to have, main valve open after the 10%, is it restore to the throne device start automatically to defend, prevent operate by mistake but make the main valve go back to the location . After putting out a fire, cut off the sensing pipe network , closing electromagnetic valve , manual ball valve and end ball valve can close the main valve . The structure is rational , beautiful : Drenched with rain the valve and controlled the pipeline and selected the high-quality steel tube for use, dispose and control the component rationally, enable controlling the valve simply , clearly. Control, easy to operate , reliable: Three kinds of control methods guarantee the main valve is opened, and enable a kind of control method to open the main valve in three kinds of control methods.
Put and defend and reduce the device inside: Have defended and has been restored to the throne and put and simplified controlling and is worthy of managing in the device . Defend the arrival which is restored to the throne the device and automatically control by the main valve , is restored to the throne and operated simply.
