High Temperature Gate Valve
Introduction:
1. The valve is mainly composed of valve body, valve cover, gate, valve stem, sealing ring, double-layer cylinder and its piston, piston rod, diaphragm, buffer mechanism, manual mechanism, manual conversion device and valve cover packing device. composition.
2. When the upper piston travels to the upper end of the stroke, the upper feedback device can be pushed up to make it send a signal; the lower end of the stroke of the lower piston can push down the lower feedback device to send a signal, which is used as the gate valve opening and closing information in the central operating room displayed on the analog instrument panel.
3. The rise and fall of the outstretched indicator rod on the upper part of the handwheel indicates whether the gate of the valve is in a rising state or a falling state.
When the gate valve is closed, the overhanging indicator rod is at the lowest position; on the contrary, when the gate valve is fully opened, the overhanging indicator rod is at the highest position. This is the on-site indication of the opening and closing status of the valve.
