1. Attention during Transportation and Installation
Do not clamp down on the pipeline during transportation, otherwise pipeline will damage and leak easily.
2. Product Introduction
This deluge valve is a directly sealed diaphragm valve. Diaphragm is made of rubber material which is imported form America with many advantages such as simple structure, reliable performance, agile installation and easy maintenance etc. Because there is no metal component such as axis and beamed seat etc, there is no rust and corrosion problem.
3. Product Composition and Work Theory
Deluge valve system is electrical control deluge valve system which is composed of electrical control deluge valve, open or automatic sprinkler (additional purchase), water flow indicator (additional purchase), hydraulic warning bell, pressure switch (additional purchase), electrical control cabinet (additional purchase) etc. When it is in standby state, there is no water in the pipeline of the system because water is closed down by the deluge valve in the water supply side of the pipeline.
First electrical detector in the protected area transmits the detected fire signal to the electrical control cabinet. Then the electrical control cabinet filtrates and deals with the signal and sends starting signal to solenoid valve on the deluge valve. The solenoid valve opens, diaphragm chamber releases pressure, the deluge valve opens and water enters into system pipeline through water supply side, discharges to the protected area through sprinkler to put out the fire.
The high or low water pressure in the diaphragm lumen of the deluge valve controls the open and close of the deluge valve. If open solenoid valve or open emergent manual quick opening valve by staff then water pressure in the diaphragm lumen falls to a certain value, diaphragm is opened by outer water supply and water enters into system pipeline to put out the fire.
Water pressure in the diaphragm lumen also can be controlled by wet-type pipeline or dry-type pipeline, viz constitutes wet-type or dry-type control system. When the sprinkler which controls pipeline cracks, water pressure in diaphragm lumen falls, valve opens.
Due to there is anti-replacement device, with correct operation, when water pressure in the diaphragm lumen releases, diaphragm pressure lumen can't increase pressure again and the valve keeps open state no matter solenoid valve or manual quick opening valve closes or not, so that during extinguishing process, the deluge valve will not close again when the solenoid valve closed due to sudden service interruption. After extinguishing, the staff open replacement ball valve then pressure lumen can increase pressure again and valve closes.
