ZSFW type temperature sensing deluge valve

Instructions for use of temperature-sensing deluge valve:
The temperature-sensing deluge valve is a small-diameter device that uses a temperature-sensing nozzle with beautiful appearance and reliable performance as the temperature-sensing control element and a compact valve body. Deluge valve. It is mainly used for fire separation in small areas such as door openings and windows. It can also be used for directional fire separation for certain equipment and areas.
Type temperature sensing deluge valve structure and working principle:
This valve system has a diaphragm structure, and the diaphragm divides the valve into a working chamber and a control chamber. While the water flow (pressure.~.) acts on the working chamber, it also enters the control chamber from the water diversion hole and acts on the diaphragm (connected to the temperature-sensing nozzle). Due to the difference in the water-receiving area of the upper and lower diaphragms, the sealing performance of the valve disc is guaranteed. .
When a fire occurs, the pressure in the control chamber is reduced due to the heating action of the temperature-sensing nozzle and the valve is opened, and the water flow is supplied to the open or water curtain nozzle to spray water to extinguish the fire.
Main specifications of temperature sensing deluge valve:
Nominal diameter:
Connection method: flange, thread
Working pressure:.~.
Nominal operating temperature: ℃, ℃, ℃, ℃
Instructions for the design, installation, operation and maintenance of type temperature-sensing deluge valve:
This valve is generally installed above the middle part of a protected and separated door or window. As a water curtain fire isolation, it can also be used for fire (roller shutter) doors for cooling protection. The nozzle on the valve body is a temperature-sensing release starting element, which is used to open the deluge valve, but it does not have a fire extinguishing effect.
.The outlet end of this valve can be connected to a water curtain nozzle or an open nozzle through a reducing tee.
.A gate valve or butterfly valve should be installed on the water supply branch pipe for debugging and maintenance.
.The temperature-sensing nozzle of this valve operates. After starting the sprinkler to extinguish the fire, you only need to turn off the water source, replace it with a new temperature-sensing nozzle, and then turn on the water source to return to the standby state.
.Users can lengthen the distance between the temperature sensing nozzle and the valve body as needed, but the length should not be too long.
.When the valve is first filled with water, it cannot be completely sealed until the control chamber is filled with water, so there may be a little water leaking from the open (water curtain) nozzle, which is normal. If the user lengthens the distance between the nozzle and the valve body, the amount of leakage during the first water supply will also increase, which is also a reasonable phenomenon.
Installation diagram of type temperature sensing deluge valve:
The manual ball valve in the picture is used for manual emergency opening when a fire occurs and the temperature rise does not reach the action of the temperature sensing element. The manual ball valve is concealed in the circle and has appropriate protection devices to prevent accidental spraying caused by arbitrary operation.
