1. The spring gas brass safety valve leakage in any leaks under operating pressure must be processed as quickly as possible, otherwise it will lead to scale and dust build-up of impurities in the sealing surface of the valve and seat. When lifting the stem, if the impurities can not afford to blow, then easily sandwiched between the sealing surface, causing the sealing surface wear, leakage increased. Some units in the safety valve leakage, self-adjusting spring safety valve spring compression, which to some with heavy compression or ten brittle locks tied with wire to make the safety valve completely ineffective.
2. The spring safety valve safety valve is not installed correctly because of its structural requirements, spring safety valve on the device or pipe should be installed vertically, especially leveraged safety valve, if not installed vertically due to the stem failure to maintain a vertical position and affect the normal timely action. When the inspection found that some non-standard equipment fails to equipment design requirements placed, resulting in horizontal or inverted safety gas aluminum valves settings affect the normal use of the safety valve. Some equipment at the time of installation, ease of maintenance, regardless of whether and check valve can not be removed so that the long-term can not be verified.
