The structure of electric globe valve in the pump valve fittings is simple and convenient for manufacturing and maintenance.Sealing of this pump valve fittings are not prone to wear and tear, sealed performance is very good, open/close the valve and the valve sealing surface relative sliding won't appear, the wear phenomenon is small in the actual use , good sealing performance, long service life.
When the valve is closed, the disc travel is small. The electric globe valve in the pump valve fittings is smaller than the gate valve, but the length of structure is longer than the gate valve.When open and closed, it is more difficult to open and close, suitable for long opening and closing.By fluid resistance, cause by the fluid channel is more twists and turns inside, fluid resistance become big,then power consumption is very big also, if use full-time disc will often erosion, at this time we need to choose a suitable other pump valve fitting.
The electric globe valve in the pump valve fittings is one of the important truncated valve, which plays a very important role in the aerospace field.As an important element used in the space equipment, the globe valve realizes the related functions of medium transportation, cut-off and adjustment, and its sealing performance directly affects the safe and reliable operation of the space equipment.
Research of the influence factor and influence rule for typical electric cut-off valve seal characteristics of pump valve fittings, it has guiding significance for the structure design for valve seal, also has intuitive sense to improve the valve's sealing performance and reliability.This fitting only has the sealing surface, because the manufacturing process is very convenient to carry on the maintenance.In the small and medium enterprises the application is also very wide.
For example ， the pipe or device made by the high temperature, high pressure which select this pump valve fittings，normally used in thermal power plant, nuclear power plant, such as high temperature and high pressure pipeline system. The effect is very good , at the same time it’s also very fast and convenient for installation and application,the turn on height is smaller and easy to adjust the flow, also pressure on the applicable scope is very wide.http://www.dmgcastings.com/
