API6D Single Plate Gate Valve
Introduction:
API6D single plate gate valve is a kind of sliding valve with parallel gate as the closing part. The closing member can be a single ram or a double ram with a spreading mechanism between them. The pressing force of the gate to the valve seat is controlled by the medium pressure acting on the floating gate or the floating valve seat. If it is a double ram flat gate valve, the stretching mechanism between the two rams can supplement this pressing force.
Use, maintenance, care and precautions:
1. The strength and sealing tests have been carried out on the valves before delivery, and all connections shall be kept in the initial state during use.
2. The operating handwheel of this series of valves is marked with the opening and closing direction sign, and the upper part of the rising stem is equipped with the opening and closing height scale for adjustment and indication.
3. When the valve is welded with the pipeline, the valve shall be opened, and the neck shall be properly protected with damp objects to minimize high temperature heat conduction to prevent damage to the sealing filler.
4. It is strictly prohibited to use an afterburner when closing the valve. When the ram is closed to the top, the hand wheel shall rotate 1/2 circle to make the ram floating.
5. During the use of the valve, a certain amount of lubricating grease shall be regularly injected into the valve cap grease fitting.
6. If the valve leaks due to wearing parts during use, it shall be replaced in time.
7. During the maintenance of the valve, the inner chamber shall be cleaned, and the transmission parts shall be greased during assembly.
8. During the storage and shutdown of the valve, the ram shall be in the closed position, and the valve shall be placed in a ventilated and dry place for long-term storage, and shall be inspected and maintained regularly.
