Safety valve should pay attention to the use of the problem
Safety valve should be noted that the use of the problem: 1. Do not press the deadline for the maintenance and inspection "steam boiler safety technology supervision regulations" and "pressure vessel safety technology supervision regulations" are provided, the safety valve should be implemented regular inspection system, generally at least annually Conduct a tuning and calibration, at the same time in the calibration of the safety valve for maintenance, to ensure its sensitive and reliable. Safety valve in use once the take-off, fall back between the valve core and the seat there will be a layer of water stains, when asked for a long time will generate iron oxide. Non-take-off safety valve after long-term use of the general sealing surface will remain some debris, generate rust and corrosion, so that the safety valve sealing performance degradation. Safety valve from the management of the use of terms, the safety valve should be a year grinding, the inspection and maintenance combined inspection. The test found that the phenomenon of overdue unverified is still more common. 2. Inaccurate pressure setting part of the use of units due to the safety valve pressure technology is not clear, the new safety valve does not press the pressure setting, direct use. Safety valve factory opened by the adjustment of the pressure, often can not meet the specific needs of users. Therefore, users must use the conditions for debugging before installation. Some use of the safety valve opening pressure of the selected value is not accurate, high or low pressure, can not guarantee the safety valve to play a real security role. 3. Safety valve selection is not correct Each safety valve only within the specified spring pressure level range, change the spring preload compression, although there is a certain amount of pressure adjustment, if the specified range, you can only change the spring Or safety valve. At present, some units do not understand the technical specifications of the safety valve, such as the type and size of the safety valve, the size of the working pressure, the level of the working pressure, etc., and do not check carefully before the installation and installation, resulting in mismatch between the operating pressure of the equipment and the pressure level of the safety valve. Some units use safety valve, only according to the flange nominal diameter of the flange will be changed to the all-Kai micro-Kai type, the safety valve emissions far below the requirement. General safety valve is suitable for all the exhaust gas, steam or liquid medium, micro-valve for the discharge of liquid safety valve. When discharging toxic or flammable media, a closed safety valve must be used. Selection of safety valve, should pay attention to the nature of the medium, temperature, corrosivity applicable to the valve material and sealing material requirements. Safety valves are generally suitable for clean, particle-free, low-viscosity fluids. 4. Leakage of safety valve Any leakage of the safety valve under operating pressure must be dealt with as soon as possible, otherwise dirt and scale of scale and dust will build up on the sealing surface of disc and valve seat. When the valve stem is raised, if the impurities can not be blown, it is easy to be caught between the sealing surfaces, causing the sealing surfaces to wear out and the leakage to intensify. Some units in the safety valve leakage, the safety valve to adjust the amount of spring compression, and its use of heavy objects or ten crisp with wire lock, the safety valve failure. 5. Safety valve installation is not correct Safety valve due to its structural requirements, the safety valve on the device or pipe should be mounted vertically, especially lever-type safety valve, if not vertical installation will stem the vertical position of the stem can not affect Its normal and timely action. Inspection found that some non-standard equipment, equipment design requirements are not placed, resulting in the level of the valve or set up, affecting the normal use of safety valve. Some equipment in the installation, regardless of whether the safety valve is easy to maintain and check, making the safety valve can not be removed and can not be long-term calibration. 6. Part of the safety valve there is a poor manufacturing quality At present, the state has implemented a safety valve manufacturing permit system, the market supply of safety valves are mostly marked by the TS logo of the professional production units. But there are still a certain number of safety valve manufacturing quality is low, geometric dimensions, machining errors greater accuracy, technical performance failed to meet the requirements, resulting in early leakage of safety valve. When purchasing a safety valve, the production unit and the real object should be carefully inspected and verified.
