valve repair often said valve sealing performance means: the process of valve repair parts of the valve to prevent the sealing ability of media leaks, it is Jiangyin Oulei Si valve repairs of the most important technical performance indicators.
When valve repair Oulei Si most concerned about the maintenance part of the valve seal has the following three:
A valve repair parts on the headstock parts (spool) and the valve seat sealing surface contact between the two Offices, valve repair in the short sealed body repair, where the leakage is called the internal leakage, which is commonly referred to as non-customs Yan, media will affect the ability to cut off the valve, for example cut off valve, internal leakage is not allowed.
Two pieces of the filler valve repair with the valve stem and the stuffing of the distribution and the Branch; body and the valve cover of the connections, both in the maintenance of the valve seal body is called an external overhaul, the two leakage is called leakage, the flow of medium into the valve from the valve leak outside. Leakage would cause material loss, environmental pollution will result in serious accidents, thus sealing the valve repair process of foreign body detection and repair also can not be ignored; for inflammable, explosive, poisonous or radioactive medium, leakage is inadmissible and therefore the ultimate criterion for valve repair must have a reliable sealing performance.
