Description
Technical Field
The utility model relates to a pressure vessel technical field, concretely relates to can bear pressure vessel of inside additional load.
Background
At present, in tests in the fields of geology, mineral products (such as coal), new materials and the like, test objects (such as rocks, coal beds and the like) are required to bear higher pressure, the stress state of the underground of hundreds of meters or thousands of meters is simulated, and test data are obtained. But sometimes require testing while under a pressurized gas medium, such as a gas, air + nitrogen + carbon dioxide medium, and the like. Because the equipment for loading the test object is arranged in the pressure container filled with the gas medium, the load transmitted by the test object needs to be borne by the structure of the pressure container, the stress condition of the original container only bearing the gas pressure can be seriously damaged, and the safety performance is not ensured. At present, a plurality of laboratories are operated separately, namely, a loading test is firstly carried out, then a gas medium test is carried out, and the initial purpose of simulating the actual condition of the test is not reflected.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a can bear inside additional load's pressure vessel, it can realize carrying out the load test to the test object under the condition of gas pressure, has guaranteed pressure vessel's security effectively.
In order to achieve the purpose, the pressure vessel capable of bearing the internal additional load comprises a cylinder body and an end cover, wherein the end cover is fixedly arranged on a foundation, an annular flange of the cylinder body is hermetically connected with the end cover, and the cylinder body is provided with a gas pipeline, an inlet and outlet hole and an observation hole; the end cover is provided with a test bed, a test object is placed on the test bed, the test bed is provided with a loading device, and the loading device loads pressure on the test object.
Furthermore, an annular boss is arranged on the end cover, and an opening of an annular flange of the cylinder body is sleeved on the annular boss.
Further, the annular flange on the cylinder body is fixedly connected with the end cover through bolts.
Furthermore, a lifting lug is arranged on the upper part of the cylinder body.
Further, the loading device is a weight.
Further, the loading device is a hydraulic oil cylinder.
The utility model has the advantages that: through setting up the end cover on the ground, the cover is located to the barrel opening inversion, and on the end cover was applied and then conducted to the ground to the gravity of loading device and experimental object to can significantly reduce the pressure of barrel, it only bore gaseous pressure, and this kind of mode can be gone on simultaneously at gas pressure environment and loading test, has guaranteed whole pressure vessel's security.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
As shown in fig. 1, a pressure vessel capable of bearing internal additional load comprises a cylinder 1 and an end cover 2, wherein the end cover 2 is fixedly arranged on a foundation 3, the cylinder 1 is a circular shell, an annular flange is welded at the bottom of the cylinder, and a plurality of bolt holes are formed in the flange. The annular flange of barrel 1 and end cover 2 sealing connection, specifically, the annular flange on barrel 1 passes through bolt fixed connection with end cover 2, is equipped with sealed cushion between barrel 1 and end cover 2. The cylinder body 1 is provided with a gas pipeline 4, a personnel inlet and outlet hole 5 and an observation hole 6, wherein the gas pipeline 4 is used for inputting gas required by various test objects. A test bed 7 is arranged on the end cover 2, a test object 8 is placed on the test bed 7, a loading device 9 is arranged on the test bed 7, and the loading device 9 loads pressure on the test object 8. The material of the cylinder 1 is common carbon steel.
The loading device 9 referred to herein is a weighted mass (dead weight). Of course, if the required loading pressure is variable, the loading device can be set as a hydraulic cylinder (dynamic load), the cylinder body of the hydraulic cylinder is fixed on a bracket which is arranged on an end cover, the cylinder rod head faces downwards, and the cylinder rod head moves downwards when being pressurized to apply different pressures to the test object. And a pressure gauge is arranged on the loading device. The pressure gauge is used for measuring the pressure exerted by the hydraulic oil cylinder. The pressure control is provided to the outside of the cylinder 1 through a pipe. The end cover 2 is provided with an annular boss, and the annular boss is sleeved with an annular flange of the cylinder body 1, so that the cylinder body 1 and the end cover 2 can be conveniently installed and positioned. In order to facilitate the movement of the cylinder body, the upper part of the cylinder body 1 is provided with a lifting lug 10, so that the cylinder body is convenient to hoist.
The working principle of the utility model is as follows:
firstly, a test object 8 and a loading device 9 are placed on an end cover 2, test equipment is adjusted, a barrel body 1 is hoisted to the position above the end cover 2, positioning is carried out through a positioning bolt and an annular boss on the end cover 2, the end cover 2 is in flange connection with the barrel body 1 through a bolt, a tester can debug an instrument and check the test equipment in the barrel body 1 through a personnel inlet and outlet hole 5, the tester climbs out the personnel inlet and outlet hole 5 and then seals the hole, at the moment, gas media for testing is filled, the loading device is started to load the test object, normal testing is carried out, the test can be static load, the static load can also be applied to the test object through changing of the loading device, all downward loads can be transmitted to a base, and the strength of the whole container is not influenced basically. When a fault occurs in the test or according to the requirement, the gas medium in the cylinder body 1 can be discharged in a decompression mode, the personnel access hole 5 is opened, and the tester enters into maintenance without hoisting the cylinder body 1 every time.
By means of the structure, the force generated by the test object of the cylinder body 1 and the loading device can be applied to the end cover 2 instead of being borne by the cylinder body 1, so that the cylinder body 1 only needs to bear gas pressure, the test safety of the pressure container for the test is guaranteed, and a safe and reliable test platform is provided for the test object loading test and the simulation of a real gas pressure environment.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes that can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those skilled in the art can be made within the scope of the claims of the present invention.
