Brief introduction of water hammer preventive valve
Water hammer valve is my company's engineering and technical personnel, referring to the United States, France and domestic water hammer type of advanced products designed and manufactured. In the transmission mode, hydraulic operation is adopted and automatic control is adopted. The valve body adopts a streamlined design with little internal head loss.
The main feature of water hammer preventive valve is that it can be used as a protection valve as well as a preventive valve. When the protective valve is applied, the pressure of the safety setting value of the guide valve in the water supply pipe can be released, and the pressure in the pipe can be kept below a safe setting value to prevent the pipe from being damaged or damaged by the high pressure or the pressure. Can be used for high-rise building fire water supply system and the system test cycle for protection, to prevent the high pressure caused by risk prevention system, can maintain the valve main valve upstream water pressure to a set value, in order to protect the main valve upstream water pressure in the region, water hammer prevention valve is used in water supply system of ideal products.
Installation and adjustment of water hammer prevention valve
1, the best way to install the main valve is horizontal and horizontal installation, valve cover facing up, before installation, to completely remove the debris in the pipe. Pay attention to the main valve flow mark arrow. After installation, make sure that no pipe stress is applied to the valve body and valve parts.
2, before the main valve to install a gate valve and a filter, the main valve should also install a gate valve in order to facilitate maintenance.
3, pressure regulating valve is closed before the first and then open the semi circle, ball valve is closed, the valve is in the open state, adjustable pressure, loosen the lock nut and the valve handwheel enlighten, clockwise screw guide valves to increase the pressure, and to reduce the pressure. Lock the lock nut after adjusting.
4. Rinse the pipe thoroughly before passing through the water.
