Simple welding flanged ball valves and ball valves feature a few big each flange ball valve is must maintain in use process, and the maintenance is daily work, to do every day. Only the maintenance of good can prolong the service life of flanged ball valves, let it give full play to the advantage for our service. Flanged ball valves, then, how to maintain? A, be sure to check out the valve switch number plate, plate and valve to ensure clear identification. If you have any damage or loss of identity, to timely subsidies. 2, to check each bracket of the flanged ball valves and joint bolt, see whether each part connection is good, if loose, be retightened. Three flange ball valve, check the status of the key parts, including the packing gland, lubrication, lubrication nut, plug, expansion joints, each part of the bonnet and valve body, look at these parts if there were any abnormal situation. Ensure that all parts can work normally. Four, in addition to these daily inspection work, to do once a year overhaul. Inspection equipment in detail all aspects of the situation, it can timely troubleshooting, to avoid a big loss due to failure. In brief, flanged ball valve maintenance is very important, stick to it can have a good effect. If improper operation or do not pay attention to maintenance, so inevitably valve failure. Like flange ball valve leakage is a common problem, when the flange ball valve failure, then to the first treatment, but be careful to find a professional maintenance staff to deal with. Generally if buy from big manufacturer flanged ball valves, so manufacturers can provide after-sales service, so you have any problem, contact the manufacturer that can solve your troubles. Pipeline conveying system in natural gas, coal, oil, water, chemical solvents and other energy transportation occupies the important position of fluid, it is said that more than 90% of the country's transportation of pipeline system for natural gas is used, the valve control is an important part of a piping system, then, what are the basic performance welded ball valve need? To introduce the below. One, zero order seal welded ball valve, place the order, butterfly valve, cut-off Industrial Valves sealing requirements must be zero level, so as to ensure effective truncation of downstream piping. If the delivery with metal particles in liquid medium, may affect the Industrial Valves seal, valve seal and the difference between primary and secondary seal, the former is metal to metal seal, the latter is the metal to rubber or PTFE material. In the event of seal failure in transmission medium, medium leakage, shall be emergency seal loss will affect the control to a minimum. Second, the fire retardant anti-static fire retardant anti-static design of welded ball Industrial Valves also to do the best, otherwise once the fire caused the leakage and leakage, damage is the second, if it is pipeline system problems of natural gas, chemical plants, there are a lot of potential safety problems. When welding ball valve ball part is non-metallic friction clamping, prone to static electricity, so the sphere conduction must be connected to the valve body. If it is transport corrosive chemical fluid medium, then choose made of anti-corrosion materials welded ball valve. In addition, poor welding ball valve and heat resistance, pressure, the basic properties such as wear resistance, the quality of the welding ball valve performance and its production is directly related to the material and production technology, so at the time of purchase welded ball valve must be looking for a reliable manufacturer is top priority.
