2. Cover the valve on the main hydrodynamic stem piping joint screw loosening, internal pressure release valve. 6. After the above items to extract, seizing type, diaphragm and a. circle is destroyed; Such as shape do not bad points to contend for its inner parts. 。 Hydrodynamic stem Industrial Valves is a kind of water is used since embellish body, no other oil lubricating oil, in case of the main valve in the zero parts damaged, please refer to the following list refers to the Marine valve in disassembly. When the electromagnetic pilot valve closing, the main valve stem water can not flow chamber, stem chamber pressure, push the diaphragm close the main valve. 7. Such as hydrodynamic stem valve diaphragm or ring has destroyed, please loose the nut on the axis core, get to decompose the diaphragm or circle, after extracting anew with a new diaphragm or ring. Electronically controlled hydrodynamic stem valve protection: hydrodynamic stem valve before to install filter, and should be easy to drain. Electronically controlled hydrodynamic stem valve products are widely used in high-rise building and living area and urban water supply network system for water conservancy project. Can replace other large valve electric device. Electronically controlled hydrodynamic stem valve using the pilot valve stem valve opening and closing, saving energy material. 5. To get off axis core, diaphragm, piston, do not damage the diaphragm. 8. Carefully examines the main valve inside of hydrodynamic stem seat, shaft core whether have damage, if there are other debris inside the main valve to sort out it outright. ( Note: the average consume loss elimination in the valve products for diaphragm and ring, other inner parts damaged little) 1. Before and after the valve on the main hydrodynamic stem end of the first gate valve closed. After adding attached plus devices, can restrict the speed of opening and closing. 4. Water power stem valve cover and spring. Ball valve opening is greater than the needle valve opening, the main valve stem indoor pressure is low, the main valve in the whole paper. Electricity flows through the magnetic valve can be successfully implemented remote sensing to open and close the valve. Q: electric hydrodynamic stem valve structure unique place and use a: electric hydrodynamic stem valve by the main valve, solenoid valve, needle valve, ball valve, micro filter device and pressure gauge of hydrodynamic stem receives and management system. 9. According to the reverse is down the order will change the zero combination device installed after the main valve, pay attention to the valve which permits jam phenomenon. Office principle of electronically controlled hydraulic valve stem when the valve from the inlet water supply, water flows through the needle valve in the main valve stem chamber, when electromagnetic pilot valve open, stem water through indoor electromagnetic pilot valve, ball valve. 3. Will take off, all the screw cover stem line indispensable in the brass nut. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you. Second, if the valve has been selected by design unit of our company model, please order according to the valves parameters directly with our sales center.
