Normal sealing surface understands deposited metal material to increase wearability, such as built-up welding 1Cr13, STL6, stainless steel.Flashboard have rigid flashboard and
Flexible disc, according to the difference of flashboard, gate valve is divided into rigid gate valve and resilient gate valve.
Gate valve structure opens and closes form according to flashboard can be divided into two kinds of structures of rising stem (RS.) and dark bar, be widely used in oil transportation, supply water
It waits in fluid circuits.Also sluice valve is applied in the equipment such as the tank car tank case of transport special media.General structure by valve body,
The compositions such as valve deck, flashboard, valve rod, sealing element, gland and handwheel.
It being rotated during conventional structure inside screw nonrising stem type gate valve by rotating handwheel band ovable valve stem, valve rod lower end screw thread is engaged with lead screw pair,
And lead screw pair coordinates with flashboard.Flashboard is so driven by lead screw pair, so as to complete the switching motion of flashboard.Prior art defect
It is that operator intuitively can not timely observe flashboard open/close states.Or the complicated heaviness of instruction device, it is unfavorable for using
It safeguards.
