Requirements to build gas stations: the eighth, the safety valve on the tank vent pipe design simpler gas station LPG tank valve vent pipe is very simple, vent nozzle towards the sky, according to the "norms" 6.7.11, paragraph 3, "the nozzle should be higher than 2m above the tank operating platform." However, this will give rise to two serious problems: ① lot of rainwater at the outlet valve, but also due to the deterioration of air quality, acid rain phenomenon is more serious, so the accumulation of rainwater generally weakly acidic gas station design, long-term effects lead to security Rusty serious internal valve, and even lead to valve scrapped; ② some birds nest in the discharge pipe, used by nesting leaves, twigs and other debris accumulate in the relief valve discharge port, resulting in difficulty can not even jump off valve gas stations while the formation of risk. Time and some gas stations in order to avoid the problem of rain poured, the safety valve exhaust port near the mouth of the direct installation of 90 ° elbow, pointing horizontal gas station, gas station consulting, because there is no cushion, easily lead to emergency discharge can not be sufficiently diffused, especially in the case of a fire accident occurred when the tank is more complex. According to some good experience, the exhaust pipe should be pointing to the sky, but the rain spout, measures should also be fortified birds, such as the nozzle diameter slightly put a light (such as aluminum) tube or in location of the discharge pipe to a minimum. No plumbing vent valve settings and other methods. Problems and Solutions of LPG filling stations exist due to various reasons, many stations there are some fire hazards in the construction, design, construction and use of the different degrees, mainly in: 1, without the approval of illegal construction. Because gas cars in China has just started, yet the introduction of national standards designed stations, each city building department this is not clearly defined, the lack of effective supervision, making the construction of the stations very irregular, some units without the approval of , illegal design gas stations, gas station tanks, illegal construction, illegal construction of stations, resulting in a number of congenital problems.
