▷The google valve plate sealing ring adopts special silicone rubber sealing ring, and the sealing pair is special silicone
rubber/stainless steel. The valve plate movement adopts two-way rolling structure.
▷In case of power failure or failure, the google valve can be opened and closed manually on site.
▷The shaft head seal of the transmission shaft of the traverse mechanism adopts the form of packing gland, which is
reliable and easy to maintain.
▷The transversal mechanism is located above the valve and adopts stainless steel tooth pin drive, which is wear-
resistant, corrosion-resistant and has a long service life.
Closed Type Electric Google Valve For Blast Furnace Gas
The horizontal movement of the closed type electric google valve plate and the loosening and clamping of the google valve sealing pair are driven by explosion-proof electric devices. The top opening compression adopts an electric spiral synchronization mechanism, and a rigid shaft connection is used to ensure reliable synchronization. The transmission parts are all enclosed and not affected by dust on site.
The closed electric google plate valve has a unique and novel structural design. When it is opened, the google valve has the characteristics of a diversion hole flat gate valve; the sealing surface is not washed by the medium and will not coke; when closed, the mechanical seal structure ensures reliable two-way sealing performance.
