Embodiment Construction
[0021] The present invention is specifically described below in conjunction with accompanying drawing, as Figure 1-5 shown.
[0022] In this embodiment, the first step, fixed installation: the fixed plate 4 is placed on the wall, the flat pad 7 is put on the connecting nail 6 and one end of the pointed thread 8 passes through the through hole 5, and a Phillips screwdriver is used. Fix it on the wall, connect the natural gas pipeline 2 with both ends of the valve body 1 respectively, put the lower end of the flexible rubber tube 10 on the natural gas pipeline 2, and fix it on the ring groove 11 with the fastening steel wire 12 To prevent air leakage, the controller 3 starts the small air pump 16, which inflates the air bag 14, and is detected by the barometer 15. During this process, this device is connected with the natural gas pipeline 2 to prevent natural gas leakage;
[0023] Second step, detection: when detecting the top, feel the position of the rotary switch 26 by the ...

The invention discloses a domestic natural gas safety protection valve comprising a valve body. The two ends of the valve body are respectively connected with a domestic natural gas pipeline, a fixingmechanism is arranged on one side of the valve body, detecting mechanisms are arranged at the two ends of the valve body, the valve body is provided with an automatic closing mechanism, one side o the valve body is provided with an alarm mechanism, one side of the alarm mechanism is provided with an air extractor, the valve body is provided with a cooling mechanism, one side of the valve body isprovided with a remote control mechanism, and one side of the valve body is provided with a controller. The valve is fixed to a wall through the fixing mechanism, whether natural gas is leaked or notcan be detected through the detecting mechanism, the valve body is closed through the automatic closing mechanism, an alarm is give through the alarm mechanism, air is extracted to the external environment through the air extractor, and the valve is cooled through the cooling mechanism when the temperature is too high. The domestic natural gas safety protection valve has the beneficial effects ofbeing simple in structure and high in practicability.
Description
technical field [0001] The invention relates to the field of valves, in particular to a domestic natural gas safety protection valve. Background technique [0002] As a common fuel, natural gas is widely used in various households. It is inflammable and explosive in nature. To prevent its leakage, a protective valve is needed. [0003] For example, the patent number is CN201820346915, and the patent name is a patent for a natural gas safety valve. Its main structure is: the two second installation balls do not block the first through hole. At this time, the pipeline is in a through state. When the valve needs to be closed, pass Manually rotate the handle to make the screw rotate 90 degrees. Since the insertion rod is a cuboid structure, the insertion rod will also rotate 90 degrees, which will drive the rotating rod to rotate 90 degrees, and drive the first installation ball to rotate 90 degrees. The rotation of the installation ball, the two second installation balls are p...
