ZDFQ907YX Double Seal Hydraulic Automatic Valve
ZDFQ907YX double seal hydraulic automatic valve designed by Dazhong Valve Group, hydraulic automatic valve closing micro-resistance slow-closing check valve, hydraulic control butterfly valve, multi-functional hydraulic (pump) control valve and many other valves are based on the excellent performance. finished product. It also has the functions of electric gate valve, electric butterfly valve and check valve. The opening and closing parts adopt butterfly plate type, with small displacement, smooth water flow and slow closing device and valve plate interlocking opening and closing; automatic quick closing.
Small flow resistance, significant energy saving effect: the opening and closing parts are disc type, with small displacement, smooth water flow, and small loss along the way and local loss.
The slow-closing device and the valve plate are interlocked to open and close; the quick-closing is automatically realized, which is not affected by the actual flow rate and head change of the pump, does not need to calculate the quick-closing time, does not need on-site adjustment by professionals, and does not need electrical components and External power, less failure points.
The three-dimensional eccentric structure of the inclined sealing pair is adopted, and the oval valve plate is inclined at 75 degrees, which shortens the valve closing stroke, shortens the sliding distance of the sealing ring, reduces the friction torque, and achieves the effect of instant clutching. .
Reliable sealing and zero leakage: It adopts the first soft and hard double sealing structure at home and abroad. The soft and hard sealing pair has the functions of anti-sand and automatic pressure compensation, and achieves the best sealing effect with the smallest friction torque.
After starting the pump, the inlet pressure of the valve must reach the predetermined value before the valve is opened, which can reach the minimum starting current of the pump to ensure the safety of the motor and electronic control facilities.
Just turn on or off the power supply of the water pump unit, and the valve will automatically open and close according to the operating procedures of the water pump. The maintenance of the components in the hydraulic cylinder can be carried out while the unit is working normally, and the key parts are made of high-quality materials, which basically do not require maintenance. .
There is a scale indicator plate that reflects the opening and closing angle of the butterfly plate, which can observe the opening and closing process of the valve. It can also send a 4-20mA analog valve position signal to the remote main control screen through the valve position signal generator to realize remote control. monitor.
