[0002] At present, the gas outlet of the traditional steel cylinder valve is an open threaded connection, that is, the gas cylinder is connected to the pressure reducing valve through the thread and connected to the gas appliance. When the gas in the cylinder is used up and the gas cylinder is replaced, the pressure reducing valve must be unscrewed. Then screw the pressure reducing valve into the gas cylinder. The replacement process is cumbersome and the operation is complicated. If the installation is not good, it will easily cause gas leakage.
And when replacing the gas cylinder, there will always be residual gas leaking out of the cylinder valve, polluting the air

Embodiment Construction
[0011] Such as figure 1 As shown, an intelligent charge-limiting spherical straight valve includes a valve body 1 connected to a steel cylinder. The valve body 1 is equipped with a spherical stop valve and an intelligent charge-limiting valve. The outer port of the valve body 1 is equipped with a quick connector 2 for quick A self-closing valve is installed in the joint 2. The quick connector 2 adopts the mother-in-law quick connector to realize the quick connection between the spherical straight valve and the pressure reducing valve. The spherical stop valve and the self-closing valve can prevent the gas in the valve body and pipeline from leaking out when changing the gas cylinder. When inflating legally, after the smart air gun recognizes that the electronic mark on the gas cylinder is valid, it activates the electromagnetic device to prevent the closing action of the smart filling limit valve, and the gas gun can inflate the gas cylinder. When inflating illegally, the sm...

The invention discloses an intelligent filling-limiting spherical straight valve comprising a valve body connected with a steel bottle. The valve body is provided with a spherical stop valve and an intelligent filling-limiting valve, and a rapid connector is mounted at an external end opening of the valve body and internally provided with a self-closing valve. The steel bottle provided with the spherical straight valve can be rapidly connected with a pressure reducing valve matched with the steel bottle through the rapid connector, so that replacement of the steel bottle is easy, rapid, safe and reliable. Through the spherical stop valve and the self-closing valve which are mounted in the straight valve, the situation that in gas bottle replacement, residual gas in the straight valve leakscan be prevented, and thus the air pollution problem is solved. Through the intelligent filling-limiting valve mounted in the spherical straight valve, illegal filling of the gas bottle can be effectively prevented, and internet-of-things management is achieved.
Description
technical field [0001] The invention relates to the technical field of steel cylinder valves, in particular to a straight valve with cut-off function and electronic intelligent filling limit. Background technique [0002] At present, the gas outlet of the traditional steel cylinder valve is an open threaded connection, that is, the gas cylinder is connected to the pressure reducing valve through the thread and connected to the gas appliance. When the gas in the cylinder is used up and the gas cylinder is replaced, the pressure reducing valve must be unscrewed. Screw the decompression valve into the gas cylinder with gas again, the replacement process is loaded down with trivial details, the operation is complicated, and installation is bad very easily causes gas leakage. And when changing the gas cylinder, there will always be residual gas leaking in the cylinder valve, polluting the air. [0003] Now, some private gas stations often carry out illegal filling, and the tradi...
