Background technology
At present, be used for the calorimeter of measurement of species heating power, one of its central module is the oxygen bomb of built-in sample, must give the oxygen bomb sufficient oxygen with burning sample before each test.Its oxygen charging method generally is to adopt the method for hand to carry out, promptly oxygen bomb is placed in the frame cabinet frame shape oxygenator, the oxygen bomb head is aimed at the oxygenation head, air-filled pore air inlet spring valve pin on the oxygen bomb head is aimed at the inflation thimble in the middle of the inflation inlet, when with the handle of subordinate press box cabinet frame shape oxygenator, inflation thimble in the middle of the inflation inlet is driven the air inlet spring valve stylus printer on the oxygen bomb head, thereby makes oxygen enter oxygen bomb from needle, and the air inlet spring needle on this oxygen bomb top is easy to damage.Simultaneously,, and cause oxygen bomb gas leakage on the inflation thimble in the middle of the inflation inlet, be difficult for perfect combustion after making the sample igniting because the carbon distribution that sample combustion produces is easy to adhere to.
The portfire of the oxygen bomb of above-mentioned calorimeter is that external cord directly is inserted on the electrode fixture splice, if loose contact causes loss of ignition easily, has reduced the success ratio of igniting.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the shortcoming of above-mentioned calorimeter oxygen bomb device, the oxygen bomb device that provides a kind of Determination of Combustion Heat reasonable in design, simple in structure, that volume is little, cost of products is low, impermeability is good to use.
Solving the problems of the technologies described above the technical scheme that is adopted is: be provided with the oxygen bomb lid in oxygen bomb tube upper end, oxygen bomb covers the left side and is provided with the electrode fixture splice, electrode fixture splice lower end is positioned at the oxygen bomb tube and left electrode column links, oxygen bomb cover be provided with air intake valve, with air intake valve and oxygen bomb tube in the admission piece that links, be provided with right electrode column in the oxygen bomb tube, on a left side electrode column and the right electrode column ignition wire is set, the burning baffle plate that is positioned at the ignition wire top is set on the left electrode column, is positioned at the tripod that crucible is equipped with in the ignition wire below.Air intake valve of the present utility model is a needle valve.The admission piece lower end is provided with admission piece is fixed on the cutting ferrule that oxygen bomb covers, and right electrode column is arranged on the cutting ferrule, is provided with insulation course between admission piece, cutting ferrule, needle valve and the oxygen bomb lid.
The utility model adopts needle valve to replace existing valve as air intake valve, overcome existing air intake valve because the firmly big shortcoming of damaging easily, and needle valve upper end can by snorkel directly and welding bottle link, thereby the shaped as frame oxygenator parts in the middle of having removed, the volume that reduces product simple in structure has reduced the cost of product.Simultaneously, admission piece of the present utility model is fixed on oxygen bomb by cutting ferrule and covers, and the pressure of having avoided combustion gas in the oxygen bomb tube is excessive and admission piece is washed open, has improved the impermeability of oxygen bomb tube.The utlity model has advantages such as reasonable in design, simple in structure, that volume is little, cost of products is low, impermeability is good, can on calorimeter, promote the use of.
