The electric flow regulating valve 5 is controlled by the controller 3 to reduce the opening degree of the electric flow regulating valve 5 along with the consumption of organic matters in the methane tank, so that the flow signal b is reduced along with the reduction of the flow signal a, a large amount of methane is generated and flows into the gas pipe 1 and the spherical tank 4 after a worker feeds the methane tank, the pressure in the gas pipe 1 and the spherical tank 4 is larger due to the fact that the opening degree of the electric flow regulating valve 5 is smaller at the moment, the impact action of the methane borne by the electric flow regulating valve 5 can be relieved due to the fact that the methane extrudes a piston mechanism in the buffer cylinder 6, the loosening degree of the electric flow regulating valve 5 caused by the impact of the methane is reduced, enough time is reserved for the opening degree of the electric flow regulating valve 5, accordingly, the flow signal b is increased along with the increase of the flow signal a, the electric flow regulating valve 5 is convenient to stably regulate the methane flow, and the methane flow of methane generated by anaerobic use equipment is kept to be dynamically balanced.
And finally, closing the designated air valve a8, sealing the corresponding branch pipe 7, rotating the corresponding buffer cylinder 6 forward to drive the internal thread pipe 9 to be separated from the branch pipe 7 along the threads, and facilitating the disassembly and maintenance of the designated buffer cylinder 6 while conveying the biogas, wherein at least one air valve a8 is required to be opened to keep the air path in at least one branch pipe 7 smooth.
The above description is only of the preferred embodiments of the present invention; the scope of the invention is not limited in this respect. Any person skilled in the art, within the technical scope of the present disclosure, may apply to the present invention, and the technical solution and the improvement thereof are all covered by the protection scope of the present invention.
