Jiangyin Europe race valve equipment overhaul Limited company specialized valve service; In the high-pressured gate valve service, the high-pressured gate valve service, the ceramic high pressure gate valve service, the platoon dregs high pressure gate valve service, the high temperature high pressure gate valve, ceramic high pressure high-pressured gate valve repairs and so on gate valve service, import high pressure gate valve had more than 30 year technical backgrounds, valve service quality and new valve same level you approve absolutely. Is quite complex in the valve service mesohigh gate valve service; The gate valve opens shuts is the damper plate, damper plate's heading and the fluid direction is vertical, moreover the damper plate has two packing surfaces, between the packing surface easy to cause eroding and the abrasion, the structure is complex, the service is quite difficult. The most commonly used pattern gate valve's two packing surfaces form wedge-shaped, the wedge-shaped angle along with the valve parameter, but different, usually is 50, medium temperature not Gao Shiwei 2°52', therefore most is mainly controls this gate valve core packing surface angle in the high-pressured gate valve service to tally absolutely with valve seat's packing surface angle ...........
