Safe-operation gas safety valve control device and control method thereof

Abstract

The invention discloses a safe-operation gas safety valve control device and a control method thereof, and relates to the technical field of gas safety valves. The gas safety valve control valve comprises a valve body, a buffer mechanism is arranged at the top of the valve body, the top of the buffer mechanism is provided with a butt joint mechanism, the buffer mechanism comprises a first air outlet pipe, piston rings, first air conveying holes, air conveying pipes, second air conveying holes, pressure releasing holes, flow limiting holes, springs, plug covers and through holes, the bottom endof the first air outlet pipe fixedly communicate with an air outlet end of the valve body, the piston rings are located inside the first air outlet pipe, the outer surfaces of the piston rings are fixedly connected with the inner side walls of the first air outlet pipe, the first air conveying holes are formed in the outer surfaces of the piston rings, the air supply pipes are located inside thefirst air conveying holes, and the second air conveying holes are formed in the outer surfaces of the piston rings. The safe-operation gas safety valve control device and the control method have the advantages of being capable of adjusting the gas pressure and being convenient to butt joint.

Description

technical field [0001] The invention relates to the technical field of gas safety valves, in particular to a gas safety valve control device with safe operation and a control method thereof. Background technique [0002] Gas is formed by the decomposition of cellulose and organic matter by anaerobic bacteria in the initial stage of coal accumulation by ancient plants. In a high-temperature, high-pressure environment, while coal is formed, gas continues to be generated due to physical and chemical effects. Gas is a colorless, odorless gas, but sometimes it can smell like an apple, which is due to the aromatic carbon The reason why hydrogen gas and gas gushes out at the same time is that the relative density of gas to air is 0.554, and the density of gas in the standard state is 0.716kg / m³, and the permeability of gas is 1.6 times that of air. It cannot maintain breathing, and when it reaches a certain concentration, it can cause people to suffocate due to lack of oxygen, and...
