Embodiment 1
[0021] Example 1, such as Figure 1-4 As shown, a natural gas valve with good fixing effect includes a valve body 1 and a limiting device 4, the surface of the valve body 1 is provided with a limiting device 4, the left end of the valve body 1 is connected with an outlet pipe 3, and the right end of the valve body 1 is connected to There are intake pipes 2.
[0022] Let’s talk about how to solve the problem that the existing natural gas valve lacks a limit fixing device for the valve when a naughty child inadvertently rotates it, causing the natural gas to leak, which is prone to fire and other accidents. The natural gas valve lacks the fixing measures for the connected pipeline, and it is easy to collide with the external force or leak easily after the external torque.
[0023] Such as figure 1 with image 3 As shown, the limiting device 4 includes an annular seat 401, the annular seat 401 is fixedly connected to the surface of the valve body 1, the surface of the annular ...

The invention provides a natural gas valve with a good fixing effect, and belongs to the technical field of natural gas valves. The natural gas valve with the good fixing effect comprises a valve body and a limiting device, wherein the limiting device comprises an annular seat; a groove is formed in the surface of the annular seat; a plurality of limiting holes are annularly formed in the groove; a rotating handle is rotationally connected to the surface of the annular seat; a connecting rod is fixedly installed on the surface of the rotating handle; a fixing plate is fixedly installed at the end, away from the rotating handle, of the connecting rod; a first spring is fixedly installed at the end, away from the connecting rod, of the fixing plate; a limiting ball is fixedly installed at the end, away from the first spring, of a vertical rod; a supporting plate is fixedly installed on the side face of the vertical rod; and a pull ring is fixedly installed at the end, away from the supporting plate, of a lifting rod. According to the natural gas valve with the good fixing effect provided by the invention, the problems that when an existing natural gas valve is used, a limiting and fixing device for the valve is lacked, and when a naughty child unintentionally rotates the valve, natural gas leaks, and accidents such as a fire disaster are likely to happen are solved.
Description
technical field [0001] The invention belongs to the technical field of natural gas valves, in particular to a natural gas valve with good fixing effect. Background technique [0002] Natural gas valve is a new type of safety supporting device for gas pipeline engineering. It is used to cut off, connect and adjust the gas in the pipeline. It is suitable for various gas medium pipelines such as city gas, liquefied petroleum gas, natural gas, and oxygen. [0003] When the parents are not at home and young children are left alone, because the existing natural gas valve is in use, there is no limit and fixing device for the valve. When the naughty children unintentionally rotate it, the natural gas will leak and it is easy to cause a fire. Wait for an accident. Contents of the invention [0004] The purpose of the present invention is to solve the shortcomings of the existing natural gas valve, which lacks a limiting and fixing device for the valve, and when a naughty child un...
