Valve repair and maintenance---2009-10-22
Long-term storage of the valves, should be regularly checked, the processing of exposed surfaces shall be kept clean and remove dirt, storage, and when the ball valve should be blocked at both ends is turned on, gate valve, globe valve, check valve, both ends of passage should be blocked and turned off, neatly stored in a room ventilated, dry place, stacked, or open storage is strictly prohibited.
Pre-installation, you must carefully check the pressure of the valve signs, path compliance with application requirements, eliminating defects caused by the transportation process and the elimination of valves of the dirt.
Installation, the valve can be installed by connecting directly in the pipe on the road. Under normal circumstances, can be installed anywhere in the pipeline, but the need to facilitate maintenance operations, pay attention to the flow medium valve should be vertical upward flow valve disc below, elevating the level of check valve can only be installed.
Ball valve, globe valve, gate valve when it is used only for full-or full closures, are not allowed to do with regulating traffic to avoid sealing surface by erosion, accelerated wear and tear. Gate valve and globe valve on the screw down sealed within the device, hand wheel rotation to tighten the top position, you can prevent media leaks from the filler Department.
Ball valve, stop valve, gate valve opening and closing should be hand wheel, lever, or other tools do not help to avoid damage to valves. Hand-wheel clockwise to shut down, otherwise open.
Packing gland bolts should be tightened evenly and should not be pressed into a distorted state, so as not to impede stem movement or bumps caused by leakage.
Valve in the use process, should always be kept clean, drive screw must be regularly lubricated and found that failure should immediately stop using, to identify clear reasons for failure.
