ZSJZ type water flow indicator

The water flow indicator is a component of the automatic sprinkler system. It uses plate blades in the water supply pipe network to control and measure the water flow signal, and connects the water flow signal to the controller to start the electric alarm system or other equipment. and determine the area where the fire occurred. The water flow indicator is suitable for wet, dry and pre-action systems.
1. The working principle and purpose of the water flow indicator:
The water flow indicator is used in automatic sprinkler fire extinguishing systems. It can be installed on the main water supply pipe or the crossbar water pipe to give the minimum information of a certain sub-area. The electrical signal of regional water flow can be sent to the electric control box and can also be used to start the control switch of the fire water pump.
The series of water flow indicators produced by our company include those with delay circuit (type) and without delay circuit (type B). Each model has: six specifications, for use in different pipelines, with delay circuit The delay time of the water flow indicator of the circuit is adjusted when leaving the factory. If the user needs other times, our company can supply it as required. The connection methods include: pipe thread, welding, and flange. There are three types for users to choose. Our company's water flow indicators are threaded type, welded type, groove type, saddle type, and flange type.
2. Main technical parameters of water flow indicator:
, Voltage: C
, Control capacity:
, Action flow:.
, Rated working pressure:.
, Delay time: (adjustable)
, Power consumption: < (when alarming)
3. Installation and maintenance of water flow indicator:
, Installation of type water flow indicator Use T-shaped pipe thread connection, connect the middle thread of the T-shaped pipe to the water flow indicator, and connect the other two ends to the pipe. This product is suitable for three pipe diameters.
The type (welded type) water flow indicator is installed at a predetermined position. Drill holes separately according to product specifications. Then remove the base of the water flow indicator and weld it on the pipe. Remove the iron knob left on the inner arm and drill holes. Dimensions below specs, drilled, above.
The type (flange type) water flow indicator is installed using a tee flange to directly connect with the pipe flange. It is suitable for pipe diameters above the pipe diameter and the length of the tee pipe is .

When connecting the water flow indicator pipeline, you must ensure that the length of the straight pipes at the front and rear is no less than twice the diameter of the pipeline. When installing, ensure that the water flow indicator is perpendicular to the horizontal plane in the center of the pipe. The direction of the arrow on the nameplate should be consistent with the direction of the water flow. For debugging and regular inspection of the water flow indicator port, you can open the test device at the end of the partition, let the water flow through for simulation testing, and check whether the water flow indicator has been modified. If a fault is found, check the water flow indicator and alarm device respectively to eliminate the fault and keep the system in the normal state. Servo status.
