7. If found 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. On the basis of using the target, function and place different can morph into remote sensing floating ball Industrial Valves, reduce the pressure valve, slow close check valve, flow stem valve, relief valve, water power electric stem valves, water pumps, stem valves, etc. Q: the classification of the hydrodynamic stem valve unique local protection and maintenance a: hydrodynamic stem valve is a hydraulic valve stem, it consists of a main valve and set the Marine valve catheter, pilot valve, needle valve, ball valve and pressure gauge, etc. 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. 8. Carefully examines the main valve seat, shaft core inner whether have damage, if there are other debris inside the main valve to sort out it outright. When entering the diaphragm ( The piston) Stem above the indoor pressure downstream of the water is discharged into atmosphere, or low pressure area, utility in the bottom of the valve plate above and below the diaphragm of the pressure value is greater than the pressure value, so the main valve disc to rev. The location of the full paper; When entering the diaphragm ( The piston) Upper stem indoor pressure downstream of the water can not be discharged into atmosphere, or low pressure zone, utility in the diaphragm ( The piston) At the top of the pressure value is greater than at the bottom of the pressure value, so will reduce the pressure of the main valve disc to the absolute closed position; When the diaphragm ( The piston) Upper stem indoor pressure value in the inlet pressure and outlet pressure halfway, the main valve disc is in adjustment, adjust the position is determined by the needle valve in the duct system and adjustable pilot valve to the conjugate. Adjustable valve can through the downstream outlet pressure and along with the change of it up or down its own small valve port, thus changes the diaphragm ( The piston) Upper stem pressure chamber, restrict the adjustment of the valve plate location. 5. To get off axis core, diaphragm, piston, do not damage the diaphragm. ( Note: the average consume loss elimination in the valve products for diaphragm and ring, other inner parts damaged little) 1. The main valve before and after the first side gate valve closed. Hydrodynamic stem valves according to the structure can be divided into two categories, the diaphragm and piston, office principle is the same, is more than the downstream pressure difference delta P, by the pilot valve stem, make diaphragm ( The piston) Hydrodynamic semi-automatic hydraulic differential operation, the absolute by adjustment, and therefore make full of the main valve disc paper or absolute closed or in the condition adjustment. 3. Will take off, all the screw cover stem line indispensable in the brass nut. 4. Take the cover and spring. 2. The piping on the main valve cover joint screw loosening, internal pressure release valve. Hydrodynamic stem valve repair and protection of hydrodynamic stem valve 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 follow the below list ordering disassembly. 。 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. 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. Three, it is very important when you use the occasion or the environment is more complex, would you please provide design drawings and detailed parameters, our engineers experts will concentrate on review and analysis for you.
