Electric enclosed flashboard valve structure and working principle of

electric enclosed flashboard valve by the main valve body, valve plate, expansion joints, a fixed set of clamping mechanism and electric hydraulic draw stem, denso, stop walking, left, on the right side of the body and other parts. : electric hydraulic draw stem drive spring clamping mechanism, the valve plate release, after putting in place, denso start walking, drive disc walk from open to close, in place after the electric hydraulic draw stem retrorse motion, automatic clamping spring clamping mechanism in place, close the Industrial Valves. Open the valve.

open flashboard valve, enclosed flashboard valve is suitable for metallurgy, chemical industry, municipal gas pipes, accord with GB6222 - The provisions of the 86 'industry coal gas safety regulation. In electric enclosed flashboard valve closed, completely cut off the line in the medium, to achieve zero leakage and sealing the electric enclosed flashboard valve product can live, remote operation, is an ideal and harmful gas, toxic gas pipeline safety shutdown devices.
