Fire Fighting System Use Ductile Iron Worm Gear Operated Signal Butterfly Valve
Product introduction:
Fire fighting valve products are control accessories on industrial and building pipelines. Fire fighting valve is the most important controlled accessory on industrial and building pipelines, normally consisting of valve body, opening and closing mechanism, and valve cover. Simple structure and reliable sealing.
Most fire valves are connected with clamps, making the complex valve installation and pipeline connection process simple, fast, and convenient. Taking pipeline connection technology a big step forward.
Signal butterfly valve is equipped with a signal device, which can send out electrical signals to show the opening and state of the butterfly plate, it is an important component of automatic sprinkler system, normally it is installed at both ends of the alarm valve group or at the entrance of each branch pipe of the system. When the alarm valve set or pipe network is being repaired, turn it off, using worm gear drive shaft and butterfly plate rotation to realize opening and closing and control flow. By rotating the hand-wheel of worm gear and worm drive device, the butterfly plate can achieve the purpose of opening and closing and regulating the flow, and the hand-wheel rotates clockwise to close the valve. A micro switch is arranged in the transmission box, which can output the closing and opening signals of the valve and show the different positions of the butterfly plate.
