Description
Technical field
The utility model relates to a kind of pressure vessel overbottom pressure explosion hazard proving installation, specifically relates to a kind of horizontal excess pressure explosion hazard of fast-open pressure container proving installation.
Background technology
The container that has mutually nested fast sealing shrinking device between end cap or the end socket that fast opening type pressure container is meant the turnover container path and main body; Because its keying speed is fast, is widely used in industries such as chemical industry, light industry, weaving, building materials and medical and health as key production equipment.For various reasons, fast opening type pressure container frequently takes place in the explosion accident of these industries.According to statistics, the fast opening type pressure container explosion accident accounts for 1/3rd of domestic pressure container accident.And the fast opening type pressure container of blasting is horizontal fast opening type pressure container more than 90%.
" fixed safe technology of pressure vessel supervision rules " regulation: the internal pressure of fast opening type pressure container discharges fully, can open quick operating valve.Be difficult to reach because of internal pressure in the practical work process discharges to put in place fully, often have overbottom pressure, accidents such as the fast opening type pressure container blast that causes thus happen occasionally.At present; The test of fast opening type pressure container mainly contains type approval test, hydro-test and air-tight test; Type approval test verifies mainly whether quick operating valve has specified action; Be functional trial, hydro-test and air-tight test are also only tested the strength character that whether satisfies regulation and are required and the sealing property requirement.The disclosed at present patent No. is ZL201010166899.6; Denomination of invention is the patent of invention of " a kind of excess pressure explosion hazard of fast-open pressure container test method and device "; But what it was directed against is vertical vessel, because the pressure vessels of great majority blast are horizontal, so it is also inapplicable.And from patent figure, see,, can't carry out exhaust and be reduced to test pressure if get into the hypertonia in the container.
Summary of the invention
The purpose of the utility model is to provide a kind of horizontal excess pressure explosion hazard of fast-open pressure container proving installation; Solve the shortcoming of no horizontal excess pressure explosion hazard of fast-open pressure container test method in the existing test method, open the door reliable scientific method is provided for horizontal fast opening type pressure container contains overbottom pressure safety.
The technical scheme that the utility model adopts is:
The utility model comprises entrance pressure pipe, first stop valve, second stop valve, exhausting pipeline, rule and tensimeter; The shell portion of horizontal door-opening pressure vessel is fixed on above the testing table; And the clip of horizontal door-opening pressure vessel is exposed outside testing table with exterior portions; The entrance pressure pipe is divided into two-way behind first stop valve; One road warp, second stop valve connects exhausting pipeline, and another road is inserted in the horizontal door-opening pressure vessel, and in inserting horizontal door-opening pressure vessel pipeline, is provided with tensimeter; Exposing bottom surface outside testing table at clip rises to stretch out and is provided with rule.
The beneficial effect that the utlity model has is:
The utility model is novel in design, reasonable idea; This device can accurately be derived explosion energy through weight, tensimeter record pressure and the volume of a container of test flight distance, fixed station height, door closure; Thereby realize containing the horizontal excess pressure explosion hazard of fast-open pressure container quantitative evaluation of overbottom pressure, open the door reliable scientific basis is provided for horizontal fast opening type pressure container contains overbottom pressure safety.
Description of drawings
Accompanying drawing is horizontal fast opening type pressure container explosion hazard proving installation.
Among the figure: 1. entrance pressure pipe, 2. first stop valve, 3. second stop valve, 4. exhausting pipeline, 5. set bolt, 6. fixed band, 7. cylindrical shell, 8. gearing, 9. clip, 10. testing table, 11. container door closures, 12. rules, 13. tensimeters.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Shown in accompanying drawing, the utility model comprises entrance pressure pipe 1, first stop valve 2, second stop valve 3, exhausting pipeline 4, set bolt 5, fixed band 6, rule 12 and tensimeter 13; Cylindrical shell 7 parts of horizontal door-opening pressure vessel are fixed on above the testing table 10 with fixed band 6 and set bolt 5; And the clip 9 of horizontal door-opening pressure vessel is exposed outside testing table 10 with exterior portions; Entrance pressure pipe 1 is divided into two-way behind first stop valve 2; One road warp, second stop valve 3 connects exhausting pipeline 4, and another road is inserted in the horizontal door-opening pressure vessel, and in inserting horizontal door-opening pressure vessel pipeline, is provided with tensimeter 13; When container inner pressure is higher than test pressure, can open exhausting pipeline 4 through second stop valve 3 to regulate according to tensimeter 13; Exposing bottom surface outside testing table 10 at clip 9 rises to stretch out and is provided with rule 12.
Described horizontal door-opening pressure vessel is made up of cylindrical shell 7, container door closure 11, clip 9 and gearing 8, and cylindrical shell 7 is connected through clip 9 with container door closure 11.
Fixing horizontal door-opening pressure vessel on testing table, capstan is connected with horizontal door-opening pressure vessel makes it have certain overbottom pressure, and tensimeter is used for measuring and control loaded pressure.Rotate clip through gearing, the container door closure of horizontal door-opening pressure vessel is in released state gradually, because interior pressure effect, the container door closure flies out, rule measuring vessel door closure flying distance.The weight of the flying distance through writing down on the rule, testing table height, container door closure, tensimeter record pressure and volume of a container can calculate explosion energy through computing formula, thereby realize containing the horizontal excess pressure explosion hazard of fast-open pressure container quantitative evaluation of overbottom pressure.
When horizontal fast opening type pressure container internal pressure is higher than test pressure, can opens exhausting pipeline 4 through second stop valve 3 and regulate according to tensimeter 13.
Judge that through end cap flying distance and testing table height overbottom pressure is dangerous, and calculate explosion energy through weight, pressure and the volume of a container of flying distance, testing table height, door closure.
The end cap flying distance is measured by rule.The initial velocity of door closure calculates in the time of can realizing opening the door through flying distance and testing table height.The door closure level flew out when the engaging tooth of clip and door closure can guarantee to open the door.
