  在家里的燃气管道上,我们都能看到一个这样的装置———自闭阀。自闭阀就是在异常的条件下阻止燃气输出,自动关闭的阀门。那么市民在使用天然气过程中,自闭阀用不用每天开关?关火时应该先关哪个阀门? 错:关自闭阀 对:不人为操作 案例:市民罗女士说,两三年来,她每天做完饭都要关闭安全自闭阀,这样做对不对? 解答:安全自闭阀是在供气异常条件下自动关闭的阀门,是一种自动保护装置,不能作为开关阀门人为操作。自闭阀在管网停气或者压力过大时会自动关闭,在正常状态下,自闭阀复位钮拉杆处于绿线刻度状态,当复位钮拉杆上的红色线弹出时,证明燃气管道内压力过大,自闭阀自行关闭;当复位钮拉杆全部收回时,则说明管网停气或者发生燃气软管脱落,自闭阀也自行关闭。 错:不关灶前阀 对:做完饭就关 案例:家住桃园路的刘先生说,他家人都有个习惯,就是做完饭不关灶前阀,这样做是否有隐患? 解答:除了错误使用自闭阀外,不关闭灶前阀也是市民的一个"通病",所谓灶前阀就是自闭阀下面的红色铜旋钮,天然气使用结束后应先将灶前阀关闭,呈横向,然后再关闭天然气灶具的阀门,否则有可能发生泄漏气体。 自闭阀状态可自检 为了保证自闭阀在管网停气或者压力过大时能够自动关闭,隔一段时间,用户可对自闭阀工作状态进行自检。检查方法为:在正常用气状态下关闭表前阀,此时自闭阀自动关闭,火焰熄灭;再打开表前阀,点燃灶具,如果灶具不能点燃,表明自闭阀关闭良好。如出现故障,用户可拨打96777服务热线请燃气公司的专业人员进行检测和维修。

Gas self-closing valve can not be a human operator In the gas pipeline on the home, we can see such a device - the self-closing valve. Self-closing valve to prevent gas output under abnormal conditions, self-closing valve. The public in the use of natural gas, self-closing valve with no switch every day? Which valve should shut off the heat? Wrong: off: self-closing valve without a human operator Case: public She has said, in 2023, she finished a day rice should turn off the security self-closing valve, do so right? Answer: Safety self-closing valve is self-closing valves in gas abnormal conditions, is an automatic protection device, the human operator can not be used as the switching valve. Will be automatically closed, closed valve in the pipe network to stop gas or excessive pressure in the normal state, self-closing valve reset button rod in the scale state of the Green Line, when the red line on the reset button rod when it pops up to prove that the pressure in the gas pipeline too large, self-closing valve itself off; when the reset button rod fully recovered, then the pipe network to stop the gas or the occurrence of gas hose off, self-closing valve itself off. Wrong: the right to do with the stove valve: finish the meal off Case: Mr. Liu, who lives in Taoyuan Road, said his family has a habit is to finish the meal off the stove valve, do so whether there are hidden dangers? Answer: In addition to the incorrect use of the self-closing valve, turn off the stove valves are also the people of a "common problem" after the end of the so-called stove valve is self-closing valve below the red copper knob, the use of natural gas should be the first stove valve closed, was horizontal, and then close the valve of the gas stove, or they may leak gas. State can be self-test self-closing valve In order to ensure self-closing valve to stop gas in the pipe network can automatically shut down when excessive pressure from time to time, the user can self-test state of self-closing valve. Inspection methods are: the table before the valve in the closed state of the normal gas, self-closing valve automatically shut down, the flame goes out; and then open the table before the valve, lit the stove if the stove is not lit, indicating good self-closing valve to close. In case of failure, the user can call 96777 service hotline professionals for testing and maintenance of the gas company.
