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 is generally slightly acidic, leading to long-term effects of internal rusting valve serious, and even lead to valve scrapped; ② some birds nest in the discharge pipe gas station, gas station consulting, used by nesting leaves, twigs and other debris accumulated in the valve exhaust port gas station, gas station storage tanks, resulting in difficulty can not even jump off valve, and the formation of risk. 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 direction, because there is no cushion gas station procedures, easily lead to an emergency can not be fully discharged proliferation, 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. Japanese investment in the construction of a liquefied gas plant in Russia's Far East, February 21, according to the Moscow Times reported that the gas station recently, president of Gazprom in Moscow met with Japanese delegation natural resources and energy companies. Both sides said that in the Russian Far East city of Vladivostok to invest in liquefied gas plant project feasibility study has been completed. Japanese investment in the construction of a liquefied gas plant in the Russian Far East, is out of the national strategic considerations, which can be expanded to store natural gas in Japan in its offshore areas. The first phase of the plant's annual production capacity of 7.5 million tons of liquefied gas design. Gas stations formalities | May Yuen Industrial (certified) | gas stations Ltd.
