Embodiment
Below in conjunction with the accompanying drawings and specific embodiment is further described to the utility model, but of the present utility model protect
Shield scope is not limited to this.
As described in Figure 1, a kind of laboratory with the explosion prevention function that loses heart of the present invention prepares acetylene unit, including gas
Body generating means I, explosion-proof air releasing device II and gas bottle 10；The gas generating unit I includes three-neck flask 1 and separatory funnel
2, the separatory funnel 2 is arranged on the middle bottleneck of three-neck flask 1；The explosion-proof air releasing device II includes hollow circular tube 3, rubber
Ring 4, piston 5, choke dividing plate 6, spring 7, baffle plate 8 and breathable membrane 9；One end of the hollow circular tube 3 is by rubber stopper and leads
Pipe is connected with one end bottleneck of three-neck flask 1, and the other end of hollow circular tube 3 is connected by rubber stopper and conduit with gas bottle 10,
The gas bottle 10 is built with water, and water surface has one layer of oil；
The inwall of hollow circular tube 3 is provided with rubber ring 4 at the mouth of pipe of one end, and the inwall of hollow circular tube 3 is close to another end pipe
Breathable membrane 9 is fixed with mouthful, the piston 5 is arranged in rubber ring 4, and is fitted with rubber ring 4, and piston 5 can be in rubber
Horizontally slipped in ring, one end on piston 5 close to breathable membrane 9 is fixedly connected with choke dividing plate 6, the choke dividing plate 6 is circle
Plate, the diameter of choke dividing plate 6 is identical with the inner diameter of hollow circular tube 3, is provided with 4~6 on piston 5 at choke dividing plate 6
