Electric remote control valve J145X
Other Products
I. Introduction:
The J145X electric remote control valve consists of a main valve, a regulating valve, and a piping system. The valve body adopts a straight-through type, and the main valve control chamber has a double-chamber structure with either a diaphragm or a piston. Compared with general hydraulic control valves, an additional control chamber is added, which enhances the control function over the main valve. It realizes multi-functional control of the pump outlet, including slow opening, full opening, slow closing, and shut-off, enabling multi-functional control of the pump outlet with a single valve and one adjustment. The piping system of this product is controlled by the regulating valve. By setting the opening degree of the regulating valve, various required control parameters, such as the opening speed and slow closing speed of the main valve, can be easily achieved.
II. Product Features:
1. Excellent water hammer prevention effect: It integrates technologies such as slow opening, check quick closing, and slow closing to eliminate water hammer, preventing damage to the water supply pipeline and pump caused by pump start-up water hammer, pump shutdown backflow, and water hammer.
2. Easy operation: No additional electronic control system is required for the valve. The valve automatically completes 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, with small hydraulic loss and good energy-saving effect.
III. Working Principle:
1. 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 opens the main valve, and the water in the upper chamber of the control chamber is slowly discharged to the outlet end through the regulating valve B, causing the main valve to open slowly. An appropriate main valve opening speed can be obtained by setting the opening degree of the regulating valve.
2. When the pump stops working, the water pressure at the inlet end drops rapidly. Under the action of self-weight and spring pressure, most of the opening degree is quickly closed to prevent backflow. The remaining opening degree is slowly closed under the combined action of water pressure in the upper and lower chambers of the control chamber. The slow closing speed forms a buffer to prevent a sharp increase in pressure.
Appropriate valve opening and closing speeds can be obtained by setting the opening degree and opening degree ratio of regulating valves A and B.
