Slag discharge valve structure features: 1, the use of flange bolts, both ends of the branch flange connection or butt welding connection 2, the opening and closing parts with semi-seal forced seal, excellent performance 3, the sealing material is wear-resistant ceramic Or wear-resistant alloy, strong abrasion resistance, abrasion resistance, durable erosion, abrasion resistance, small friction, reliable sealing 4, the body outlet flow junction knot is reasonable, not slag, opening and closing flexible, not card Resistance 5, the stem by quenching and nitriding the surface treatment, good engage in corrosive, abrasion resistance and wear resistance 6, the large diameter set rolling bearings, easy to open and close the gate valve installation and maintenance Notes: 1, Hand wheel, handle and transmission mechanism are not allowed to lift, and no collision. 2, double gate valve should be mounted vertically (ie stem in a vertical position, the hand wheel at the top). 3, with bypass valve gate valve should be opened before opening the bypass valve (to balance the pressure difference between import and export and reduce the opening force). 4, with the gear valve, according to the instructions of the product installation instructions. 5, if the valve is often used switch, lubrication at least once a month.
