Abstract
A high-pressure container explosion suppression device is manufactured under the bursting pressure, wherein the bursting pressure of an explosive tube is lower than tubular wall bursting pressure of a pressure container but is higher than the working pressure of the pressure container. Due to the fact that the explosion suppression device can be disposable, the pressure container can normally work after the explosion suppression device is replaced. Therefore, the potential safety hazard brought by non-timely replacement of a fusible piece is eliminated.
Description
Technical field
This technology belongs to high-pressure bottle technology.
Background technology
The decompression during hypertonia of current pressure cooker equal pressure container, generally adopt the composition such as air vent and fuse sheet, other bleed passages of also employing had, such pressure cooker, if air vent is blocked, when pressure raises, just dependence fuse sheet is only had, but, fuse sheet is but easily aging, if consumer does not know to change fuse sheet or be unwilling to change fuse sheet for various reasons, if the food boiled is that the consistency ratios such as starchiness are higher, if and pressure cooker is long for service life, metallicity is aging, then be easy to blocking air vent accidents caused.
Summary of the invention
Technical scheme: detonation seal comprises following three necessary assemblies, explosive, securing member and safety screen, the burst pressure of explosive is between the operating pressure and the burst pressure of container inner wall of pressure vessel, generally to ensure safety higher than the certain value of operating pressure, when the operating pressure of pressure vessel is inadequate, easy booster can use sealing ring to seal.
Detailed description of the invention: in the proper site design and installation hole of pressure vessel, the installing hole design of general high voltage pot is advisable on pot cover, explosive is generally easy booster, its rear end end face diameter is greater than installing hole, easy booster outer wall there is screw thread in order to installation, securing member is generally nut, easy booster pierces into installing hole, work is got final product with nut check, easy booster front end is closed, rear end will communicate with container, its pipe thickness is greater than nose thickness, burst to avoid tube wall and destroy chamber wall, different explosion values is obtained to adapt to the container of different pressures by the thickness changing front end, if identical with container material quality, its nose thickness is lower than container wall thickness, when container normally works, the burst pressure of easy booster is greater than the pressure of normal work, easy booster can not burst, when container inner pressure raises extremely, easy booster front inner wall is the same with the pressure that container inner wall is subject to large, because easy booster front end burst pressure is less than the burst pressure of container inner wall, therefore, front end bursts, easy booster becomes siphunculus by not siphunculus, gases at high pressure in release container, protection vessel safety, after this user must change easy booster, pressure vessel could normally work, safety screen is fixed on pressure vessel, block the front end of easy booster, but there is certain safe distance apart from easy booster, with the easy booster of applicable installation for basic principle, after explosive pipe explosion, its front end sliver and gases at high pressure are blocked by safety screen, in case cause the accident, the scope that when impact resistance of safety screen should be greater than explosion, the impulsive force of sliver is certain.
Claims (4)
1. a high-pressure bottle detonation seal, it is characterized in that: high-pressure bottle detonation seal comprises following three necessary assemblies, explosive, securing member and safety screen, the burst pressure of explosive is between the operating pressure and the burst pressure of container inner wall of pressure vessel, generally that when the operating pressure of pressure vessel is inadequate, easy booster can use sealing ring to seal higher than the certain value of operating pressure to ensure safety.
2. according to high-pressure bottle detonation seal according to claim 1, described explosive is characterized in that: explosive is easy booster, its rear end end face is greater than the installing hole of pressure vessel in order to installation, its front end is closed, rear end will communicate with container, and the pipe thickness of easy booster is greater than nose thickness, when easy booster is identical with pressure vessel material, its nose thickness will be thinner than the thickness of container tube wall, and the outer wall of easy booster has screw thread in order to installation.
3. according to high-pressure bottle detonation seal according to claim 1, described securing member is characterized in that: securing member is generally nut, and the external screw thread of its internal thread and easy booster outer wall coordinates to be installed.
4. according to high-pressure bottle detonation seal according to claim 1, described safety screen is characterized in that: safety screen is fixed on pressure vessel, in the front end of easy booster, certain safe distance is had apart from easy booster front end, principle is installed as with what do not hinder explosive pipe, safety screen is sliver and the gases at high pressure of the easy booster front end blocking explosion, the scope that when impact resistance of safety screen should be greater than explosion, the impulsive force of sliver is certain.
