Description
Technical Field
The invention relates to an internal pressure experiment platform.
Background
Because different initial geometric defects are inevitably introduced on the surface of the container due to different production processes in the production process of the pressure container, the actual bearable load value of the pressure container is greatly different from the theoretical value, and the different initial geometric defects are different from the theoretical value, so that the influence of the defects and other factors on the load capacity needs to be tested through a pressure experiment at the beginning of the design and manufacture of various pressure-bearing containers.
The existing external pressure experiment platform does not consider the discharge of gas in the container, and the experiment result is influenced by the way of additionally opening a hole at the top of the container; the existing experiment platform does not fully consider the installation mode of the sensor, cannot avoid the relative displacement between the bracket and the sample by building an external sensor bracket so as to influence the experiment result, and cannot ensure that the installation position of the sensor such as similar displacement is relatively fixed every time so as to eliminate the installation error; the sample connecting end of the existing external pressure experiment platform can not be reused, which can cause resource waste.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention provides an internal pressure experiment platform which is simple to operate, high in experiment efficiency and low in experiment difficulty.
The technical scheme adopted by the invention for solving the technical problems is as follows:
the utility model provides an interior pressure experiment platform, includes support, lower flange and upper flange, lower flange installs on the support, and upper flange passes through bolt fixed connection with lower flange, the up end of upper flange be through welded connection with the test piece, and the blast pipe stretches into the inner chamber of lower flange, the blast pipe has last exhaust pipe mouth and lower exhaust pipe mouth, lower flange and drain pipe connection, the last manometer of connecting of drain pipe, the drain pipe is equipped with the mouth of pipe of intaking and the mouth of pipe of pressurizing.
Furthermore, the upper flange is connected with a sensor bracket, and a mounting hole for mounting the sensor is formed in the sensor bracket.
The internal pressure experiment platform has the characteristics of repeated use and suitability for various internal pressure tests. The test samples are connected with the experiment platform through the upper flange, and different types or flanges with different transition sections can be selected for connecting the test samples with different specifications and sizes, so that the universality is wide; other parts of this experiment platform have higher thickness relatively, can not produce plastic deformation in the experiment and influence the experimental result, but reuse with sample spare welded connection, the sexual valence is higher. The platform is pressurized with liquid for safety. The experiment platform is simple to operate, high in experiment efficiency and low in experiment difficulty.
The invention has the following beneficial effects: the operation is simple, the experiment efficiency is higher, the experiment difficulty is smaller, and the experiment device can be repeatedly used.

In this example, the experimental procedure was as follows:
(1) and welding a sample to be tested on the upper flange, and selecting a proper exhaust pipe according to the size of the sample to be mounted on the upper exhaust pipe opening 3.
(2) The upper half part of the experiment platform is hoisted to a proper position of the experiment platform, a plurality of proper sensor supports are selected for installation, the sensors are directly installed on the screw rods after the bolts are completely installed, and the sensors are fixed through nuts.
(3) And (5) installing various sensors required by the experiment, debugging to a proper position, and installing a pressure gauge.
(4) The installation inlet tube, force pump, add the liquid operation in advance to experimental apparatus, both the container has been full of when treating mouth of pipe 5 beginning outflow liquid, closes the gas vent valve, closes the water inlet valve.
The experiments were carried out: the pressure pump was turned on to perform the internal pressure test.
And after the experiment is finished, relevant experimental data, photos and other information are stored. And opening a valve at the water inlet opening 8 of the water inlet pipe, slowly releasing the pressure in the pressure cavity, and discharging the liquid in the cavity. And unloading the bolts, and taking down the sensor directly and the upper flange. The test specimen from which the experiment was completed was cut off from the upper flange for use.
