Hydraulic valve of the main valve with single cavity and double cavity type two kinds. Single cavity the main Industrial Valves by the diaphragm drive can be divided into upper and lower two stem cavity, on stem cavity after piping and upstream petition, stem cavity under the downstream. Hydrodynamic stem valve which is driven by hydraulic power and the diaphragm of the stem valve, main valve ordinary consists of basic body and driving devices. The differential pressure valve is mainly depend on, lumen operating the movement of the diaphragm. The differential pressure valve is mainly depend on, inferior vena operating the movement of the diaphragm. Hydrodynamic valve widely used in building pipelines, industrial water supply, fire fighting equipment, hvac and border irrigation system and so on various aspects of Marine valves, ordinary as lower pressure, holding pressure, pressure, flow adjustment, stem water standard and the prevention of water hammer, etc. 。 Double cavity of main valve is tightly in the disc close and add a piece of isolation between the diaphragm plate, so it is, in the three stem cavity, on stem cavity after piping and upstream petition, stem cavity can be arbitrary power supply period, in the stem cavity still downstream of the petition. Q: hydrodynamic stem valve structure and work principle of a: hydrodynamic stem valve is one of many people is very common in the daily life of the valve, and the survival of many people, the other is in danger. 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.
