Abstract
The utility model provides an explosion-proof device used for chemistry teaching. The explosion-proof device used for chemistry teaching includes an explosion-proof film, a deflating tube port, an air tube, a copper mesh coil, an explosion-proof tube, an explosion-proof necking-down tube, a one-way valve floater and a one-way valve. The explosion-proof tube is a main piece. The explosion-proof tube is integrally in a cylindrical structure. The lower end of the explosion-proof tube connects with the explosion-proof necking-down tube. An inner lower part of the explosion-proof tube penetrates into the explosion-proof necking-down tube and is provided with the copper mesh coil. The lower end of the explosion-proof necking-down tube is connected to the one-way valve. The one-way valve floater is arranged in the one-way valve. An upper end port of the explosion-proof tube is the deflating tube port. The explosion-proof film is arranged on the deflating tube port. The air tube in a form of a three-way pipe is arranged in a position slightly lower than the upper end of the explosion-proof tube. The explosion-proof device used for chemistry teaching in the utility model is simple in integral structure, convenient in operation and usage, and has good stability and high reliability. By using the explosion-proof device used for chemistry teaching in the utility model, the generation of tempering phenomenon can be prevented, thereby avoiding accidents caused by tempering.
Description
Technical field:
The utility model relates to chemistry teaching and uses teaching aid, relates in particular to a kind of chemistry teaching and uses explosion-protection equipment.
Background technology:
In the process of general chemistry teaching; Especially in the chemical experiment in process of general chemistry teaching; Often to carry out the chemical reaction experiment of the combustion experiment and the related properties of a series of inflammable gass; Such as: carbon monoxide, hydrogen, sulfuretted hydrogen, ammonia, methane, methyl alcohol, ethene, ethane, ethanol, acetylene, ether, propylene, propane, butane and benzene etc.; Sneak into air in certain amount in inflammable gas that these are commonly used or the steam, when reaching explosion limits scope and ignition temperature, violent blast will take place.What especially in the chemical experiment process, often adopt is the glass reaction container, and the consequence that explosion time caused can be more serious.
The utility model content:
The purpose of the utility model is, overcomes the weak point of prior art, provides a kind of chemistry teaching to use explosion-protection equipment, especially prevents the generation of tempering phenomenon, avoids the accident that takes place because of tempering.
The described a kind of chemistry teaching of the utility model is used explosion-protection equipment, includes blow-out disc, nosepipe, wireway, copper wire net volume, explosion stack, explosion-proof necking down pipe, retaining valve float and check valve body and forms.Explosion stack is the main component of the utility model, and integral body is structure cylindraceous, and the lower end of explosion stack is connected with explosion-proof necking down pipe, and the bottom is provided with the copper wire net volume in the explosion stack in explosion-proof necking down pipe.The lower end of explosion-proof necking down pipe is connected with check valve body, is provided with the retaining valve float in the check valve body.The port of explosion stack is a nosepipe, and nosepipe is provided with blow-out disc, in downward slightly position, the upper end of explosion stack, is provided with the wireway of three-way pipe form.
The described a kind of chemistry teaching of the utility model is used explosion-protection equipment, and one-piece construction is simple, and is easy for operation, good stability, and reliability is high.Use the described a kind of chemistry teaching of the utility model to use explosion-protection equipment, especially can prevent the generation of tempering phenomenon, avoid the accident that takes place because of tempering.
Description of drawings:
Accompanying drawing 1 is the structural representation of the said a kind of chemistry teaching of the utility model with explosion-protection equipment.The explosion-proof necking down pipe of 1-blow-out disc 2-nosepipe 3-wireway 4-copper wire net volume 5-explosion stack 6-7-retaining valve float 8-check valve body.
Embodiment:
Existing with reference to accompanying drawing 1; Explain as follows in conjunction with embodiment: the described a kind of chemistry teaching of the utility model is used explosion-protection equipment, includes blow-out disc 1, nosepipe 2, wireway 3, copper wire net volume 4, explosion stack 5, explosion-proof necking down pipe 6, retaining valve float 7 and check valve body 8 and forms.Explosion stack 5 is main components of the utility model, and integral body is structure cylindraceous, and the lower end of explosion stack 5 is connected with explosion-proof necking down pipe 6, and the bottom is provided with copper wire net volume 4 in the explosion stack 5 in explosion-proof necking down pipe 6.The lower end of explosion-proof necking down pipe 6 is connected with check valve body 8, is provided with retaining valve float 7 in the check valve body 8.The port of explosion stack 5 is nosepipes 2, and nosepipe 2 is provided with blow-out disc 1, in downward slightly position, the upper end of explosion stack 5, is provided with the wireway 3 of three-way pipe form.The described a kind of chemistry teaching of the utility model is used explosion-protection equipment, and one-piece construction is simple, and is easy for operation, good stability, and reliability is high.Use the described a kind of chemistry teaching of the utility model to use explosion-protection equipment, especially can prevent the generation of tempering phenomenon, avoid the accident that takes place because of tempering.
