ZSJZSaddle type water flow indicator

Water flow indicator ZSJZ is automatic sprinkler extinguishing systems components, with the help of water supply pipe network within the plate blade

Water flow indicator ZSJZ is automatic sprinkler extinguishing systems components, with the help of water supply pipe network within the plate blade measurement control flow signal, and the flow signal is connected with the controller, in order to start the electric alarm system or other equipment, and to determine the fire. Water flow indicator applied to wet, dry, preaction system.
A flow indicator, ZSJZ work principle and application:
ZSJZ flow indicator, used for automatic sprinkler system, it can be installed in the main water supply pipe or rod pipe, given a regional area of water flow signal, the electric signal can be sent to the electronic control box, can also be used to start the fire pump control switch.
I produced a flow indicator series products, with a time delay circuit ZSJZ （ A ） and without the ZSJZ delay circuit （ B ）, each model are: 50,65,80,100,125,150, six kinds of specifications, for different conduit is used, with the delay circuit flow indicator, the factory Shi Yanchi time to30s, such as user needs other time, my company can according to the requirements of suppliers, connecting method are: pipe thread, flange, welding three types for the user to choose. My company flow indicator respectively thread, welding type, groove, saddle type, flange type.
In two, the main technical parameters of ZSJZ flow indicator:
1, voltage: DC24v
2, control volume:10W
In 3, the action flow rate:15-37.5Lmin
4, rated working pressure:1.2Mpa
In 5, the delay time:2-90s （ adjustable ）
6, power: < 200mA （ alarm ）
In three, ZSJZ flow indicator installation and maintenance:
In 1, ZSJZ ' thread ' flow indicator installed by tee pipe thread connection, the T-shaped pipe thread connection with the middle flow indicator, the other ends are connected with the pipeline, the product applicable to diameter 50,65,80, three.
In 2, ZSJZ ' welded ' flow indicator installed at a predetermined position, according to the product specification, hole drilling, then the flow indicator base down welding in pipeline, remove stay arm iron aneurysm, borehole size below 80specifications, more than 100drilling drilling33mm,48mm.
In 3, ZSJZ ' flange type ' flow indicator is installed with three links flange directly with the pipe flange connection, applicable to diameter above 100mm, three way pipe length is 180mm.
4, wiring, according to the line end" +"" +" DC24V line connected with the power supply end," -" black ground" open" end yellow line alarm system signal end," public " blue line for the reduction of lead with" +" end.
5, is connected with the water flow indicator line, must ensure that the same before and after the straight length of not less than5 times the diameter of the pipeline, should be installed to ensure the water flow indicator and the center line is vertical to the horizontal plane, the direction of the arrow on the nameplate shall be in line with the direction of flow, water flow indicator debug and check regularly, can open partition terminal test device, pass water flow simulation test, check whether the transformation of flow indicator, if found fault, should check water flow indicator and alarm device, troubleshooting, make the system in servo.
