The invention discloses a safety oxyhydrogen flame extinction device for ampule filling and sealing, which can solve the problem that the flow rate of gas at a nozzle is reduced because oxyhydrogen gas supply pressure is reduced during use. When gas pressure is lower than a first set pressure value, a two-position three-way valve cuts off oxyhydrogen gas supply, and is connected with compressed air (or nitrogen), and the compressed air is conveyed to the nozzle to extinct the flame on the nozzle and prevent backfire. When the flame on the nozzle returns to a fire-stopping pipe, the temperature of a shell of the fire-stopping pipe is raised, and when the temperature reaches a set temperature value, a temperature control switch sends a control signal to cut off the oxyhydrogen gas supply and connect compressed air to extinct the flame on the fire-stopping pipe and prevent the flame from entering gas supply equipment after the flame burns through the fire-stopping pipe. Moreover, after the compressed air (or hydrogen) is connected, an oxyhydrogen supplementing gas source is used for supplementing gas into the oxyhydrogen gas source to assist in restoring the normal pressure of the oxyhydrogen gas source and an oxyhydrogen mixed gas source of a pipeline of the nozzle.
Description
technical field [0001] The invention relates to a hydrogen-oxygen flame safety extinguishing device for ampoule filling. Background technique [0002] In the past, fossil fuel gas combustion flames were used in the filling and sealing of ampoules in the pharmaceutical industry (water injection drawing and sealing). Non-corrosive, non-polluting, no solid combustion particles, and the combustion product is water. Therefore, the hydrogen gas source is widely used in the sealing of pharmaceutical ampoules. However, because hydrogen-oxygen mixtures burn several times faster than fossil fuels, hydrogen-oxygen mixtures are more prone to backfire and deflagration than fossil fuels. Although the hydrogen-oxygen generator equipment adopts the working method of production and use, the equipment does not store gas, the energy storage in the gas pipeline is small, and there is no safety hazard, but the sound produced by backfire and deflagration still brings psychological barriers to us...
