At present, some units of the Gas Valve For Water Heater model specifications, aperture size, working pressure rating and other technical indicators do not understand, the installation is not carefully checked before purchasing, resulting in equipment operating pressure relief valve spring pressure levels do not match. Some units chosen spring safety valve, the only mistake the entire Kai nominal diameter to Weiqi, emissions are far below standard safety valve flange interface according to the public. General safety valve suitable for emission of gases, vapors or liquid medium, Weiqi safety valve for discharging liquid medium. When the emissions of toxic or flammable media, you must choose a closed valve. The selection of the safety valve, should pay attention to the nature of the medium, temperature, corrosive material is suitable for the requirements of valves and sealing materials. General safety valve for cleaning, no fluid particles, low viscosity.
Pressure setting is not accurate to use the unit as a result of partial pressure safety valve set technical requirements are not clear, the safety valve is not required to purchase a new set pressure, directly. When the valve opening pressure factory adjusted, often do not meet the specific needs of the user. Therefore, the user must use the debug condition before installation. Some units use a spring safety valve opening pressure of the selected value is not accurate, constant pressure is high or low, can not guarantee the Natural Gas Safety Valve really play a security role.
The selection of an incorrect valve spring pressure levels only within the specified operating range, changing the amount of compression spring preload, although there is a certain amount of pressure adjustment, if out of range, you can only replace the spring or valve.
