Fire Fighting Signal butterfly valve
● Brief
This butterfly valve is suitable on system such as petroleum, chemical industry, foodstuff, medicine, papermaking, water and electricity, shipping, plumbing, the smelting and sources of energy etc the pipe route. Can regard on gas, liquid, semifluid as well as sloid powder pipes and power lines and the container of many kinds of corrosive ness and non-corrosiveness adjusts and dams ariver the equipment use. Especially extensively being suitable in high layer of building fire prctection system reaches other to show in the pipes and power lines system of valve switch state.
● Technical DATA
Nominal Diameter DN(mm)：50(2”)~250(10”)
Nominal Pressure PN(MPa)：1.0~1.6
Testing Pressure (MPa)：Shell:1.5~2.4 Sealing:1.1~1.76
Suitable Mediums:Fresh water、Sewage、Sea water、Air、Steam、Food、Medicine、etc.
Working Temperature: -15~+150
Microswitch capacity:AC 220V 1A DC 30V 0.5A
● Features
1, Small in size and light in weight. Easy instllation and maintenance. It can be mounted wherever nedded.
2, Siple and compact construction, quick 90 degrees on-off operation.
3, Miniminzed operating to rque, energy saving.
4, Flow curve tending to straight line. Excellent regulation performance.
5, Long service life. Standing the test of tens of thousands opening/closing operations.
6, Bubbles-tight sealing with no leakage under the pressure test.
7, Wide selection of materials, app;icable for various mdeilum.
8, Gate valve, globe valve, cock, glue pipe valve and diaphragm valve altogether, especially reaching and need show in the pipes and power lines system of valve switch state at high layer of building fire protection system, all available this valve is replaced.
● The Work Principle
1, This signal butterfly valve is by the pot wheel worm-drive device drive tuming axle and the butterfly board revolving realizes opening and close and controls the volume of flow.
2, Revolving the worm gear worm-drive device handwheel, making butterfly board achieve the purpose opening and close and adjusts the volume of flow, that the handwheel clockwise revolves closes down for the valve.
2, The worm gearworm-drive device chest is set up the microswitch inside the body andis had two kinds of versions:
(1) At the gearing chest has out inside the body to and the pass to two microswitchs. Two switches move respectively at the valve standard-sized sheet with when cutting out, the pilot lamp power supply in the connection control room “valve leaves” “valve pass”, mades accurately shows the valve switch state.
(2) In the gearing chest body. The signalis closed down by the export valve to the microswitch action when the butterfly biard is by 0~40°seat, and another can be sended out the valve and opening the signal to often closing the contact during 40~90°seat. Can adjust the cam that the pressure was touches the microswitch, and show the different seats of buttfefly board place.
