DY203X valve yo gucapa kandi yo gukumira inyuma

I. Ingeragire:

DY203X pressure-reducing and check valve is an intelligent valve installed at the outlet of water pumps in high-rise building water supply systems and other water supply systems, used to prevent medium backflow, water hammer and water surge. This valve integrates three functions: electric valve, check valve and water hammer eliminator, which can effectively improve the safety and reliability of the water supply system. It integrates the technical principles of slow opening, fast closing and slow closing to eliminate water hammer, preventing water hammer during pump start-up and pump shutdown. By simply operating the pump motor switch button, the valve can automatically open and close according to the pump operating procedures, with large flow and small pressure loss. This valve is installed at the pump outlet, sequentially realizing functions such as slow opening, full opening, fast closing and slow closing. This product is used at the pump outlet pipelines of high-rise building water supply systems and other water supply systems, preventing and reducing water hammer and water surge in the pipelines during pump start-up and shutdown, preventing water backflow to protect the pump and maintaining pipeline safety.

II. Imikorere y’ubwubatsi:

This product is composed of a main valve, a regulating valve and a pipeline system. The valve body adopts a straight-through type valve body. The main valve control chamber is a double-control chamber structure with a diaphragm or piston type. The control chamber has one more chamber than ordinary hydraulic control valves, increasing the control function of the main valve. It realizes multi-functional control of the pump outlet, including slow opening, full opening, slow closing and shut-off, achieving multi-functional control of the pump outlet with one valve and one adjustment. The pipeline system of this product is controlled by a regulating valve. By setting the opening degree of the regulating valve, various required control parameters can be easily realized, such as the opening speed and slow closing speed of the main valve.

III. Inyungu z’akazi:

When the pump starts, water pressure acts on the lower part of the main valve disc and the lower chamber of the control chamber. This pressure causes the main valve to open. The water in the upper chamber of the control chamber is slowly discharged to the outlet end through the regulating valve B, and the main valve opens slowly. By setting the opening degree of the regulating valve, an appropriate main valve opening speed can be obtained. When the pump stops working, the water pressure at the inlet end drops rapidly. Under the action of its own weight and spring pressure, most of the opening degree is closed quickly to prevent water backflow. The remaining opening degree is closed slowly under the combined action of the water pressure in the upper chamber and the lower chamber of the control chamber. The closing speed is slowed down to form a buffer, preventing a sharp increase in pressure.
By setting the opening degree and opening degree ratio of regulating valves A and B, appropriate valve opening and closing speeds can be obtained.

IV. Imikorere y’akazi:

1. It is very effective in preventing water hammer. It integrates the technologies of slow opening, fast closing and slow closing to eliminate water hammer, preventing damage to water supply pipelines and pumps caused by water hammer during pump start-up, water backflow during pump shutdown and water hammer.
2. It is easy to operate. There is no need to install an additional electric control system for the valve. The valve automatically completes the control functions in sequence along with the start and stop of the pump. Appropriate control parameters can be obtained by setting the opening degree of the regulating valve.
3. The valve body adopts a full-channel, straight-through and streamlined design. It has small hydraulic loss and good energy-saving effect.
