Abstract
Description
Technical Field
[0001] The utility model relates to the field of rubber experimental equipment, in particular to a rubber corrosion-resistant liquid experimental device with adjustable pressure. Background Art
[0002] Rubber products come into contact with various liquids during use (including non-volatile oils and volatile, corrosive reagents). Therefore, their liquid resistance must be tested before use. Test items primarily include changes in hardness, tensile strength, elongation at break, and volume. Currently, sealed cans lack sufficient corrosion resistance, which can easily affect test results. Furthermore, they lack pressure relief devices, making it impossible to control the internal pressure of the can. This makes it impossible to determine the pressure inside the can after the test, making it dangerous to open it rashly. Therefore, the development of a test device with excellent sealing and high safety is urgently needed. Summary of the Invention
[0003] The utility model aims to provide a rubber corrosion-resistant liquid experimental device with adjustable pressure, aiming to solve the existing problems.
[0004] The technical solution adopted by the utility model is: a rubber corrosion-resistant liquid experimental device with adjustable pressure, comprising a tank body, the tank body is cylindrical, the top of the tank body is a tank mouth, the tank mouth is provided with an outer eaves, an annular groove and a plurality of screw holes are provided on the end surface of the outer eaves, a sealing ring is installed in the annular groove, the sealing ring is positioned in the annular groove and protrudes upward, a sealed tank cover is provided on the tank mouth, the sealed tank cover is fastened to the tank mouth by bolts, a pressure gauge and a pressure relief valve are provided on the sealed tank cover, the pressure gauge and the pressure relief valve are respectively fastened to the upper end of the sealed tank cover, and a polytetrafluoroethylene coating is respectively provided on the inner wall of the tank body and the bottom surface of the tank cover.
[0005] A further technical solution of the present invention is: the thickness of the polytetrafluoroethylene coating is 0.02 mm.
[0006] A further technical solution of the present invention is that the cross-sectional thickness of the sealing ring is 5 to 10 mm.
[0007] A further technical solution of the present invention is that a handle is provided on the sealed can cover for easy access.
[0008] The beneficial effects of the present invention are as follows: due to the adoption of the above technical scheme, the present invention is a rubber corrosion-resistant liquid experimental device with adjustable pressure, which can always detect and maintain the internal pressure of the sealed tank through the cooperation of the pressure gauge and the pressure relief valve. The set pressure relief valve can also ensure that the sealed tank will not be over-pressurized, avoiding the risk of explosion. It has corrosion resistance, good sealing performance, and high safety. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 This is a structural schematic diagram of a rubber liquid resistance test device with a pressure relief valve according to the present invention;
[0010] Figure 2 It is a schematic diagram of the top structure of the sealed can cover of the utility model. DETAILED DESCRIPTION
[0011] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0012] Example:
[0013] like Figure 1 、 2 The shown device is a rubber corrosion-resistant liquid experimental device with adjustable pressure, comprising a tank body 1, which is cylindrical and has a tank mouth at the top. The tank mouth is provided with an outer eaves 11, and an annular groove and a plurality of screw holes are provided on the end face of the outer eaves 11. A sealing ring 3 is installed in the annular groove, and the sealing ring is positioned in the annular groove and protrudes upward. A sealed tank cover 2 is provided on the tank mouth, and the sealed tank cover 2 is fastened to the tank mouth by bolts 8. The sealed tank cover generates deformation pressure on the sealing ring through the extrusion force of the bolts to achieve a sealing effect. A pressure gauge 4 and a pressure relief valve 5 are provided on the sealed tank cover, and the pressure gauge and the pressure relief valve are respectively fastened to the upper end of the sealed tank cover. The pressure gauge includes but is not limited to a pointer pressure gauge and an electric pressure gauge. The pressure gauge can display the internal pressure of the sealed tank in real time, and the pressure relief valve can release the pressure inside the sealed tank that exceeds the experimental requirements by adjusting the pressure relief pressure. The pressure gauge and the pressure relief valve can be used together to detect and maintain the internal pressure of the sealed tank at all times. The pressure relief valve setting also ensures that the sealed tank will not be over-pressurized and cause explosion risks. The pressure gauge reading can be displayed to avoid danger when removing the sealed tank cover. All parts that come into contact with experimental materials are provided with a polytetrafluoroethylene coating 7, including the inner wall of the tank and the bottom of the tank cover. This ensures that the experimental materials in the tank will not be contaminated by reasons such as tank corrosion, which will affect the experimental results. At the same time, the non-stick properties of polytetrafluoroethylene facilitate cleaning of the inside of the tank after the experiment, preventing the experimental materials from being uncleaned and affecting the results of the next experiment.
[0014] Furthermore, the thickness of the polytetrafluoroethylene coating is 0.02 mm.
[0015] Furthermore, the cross-sectional thickness of the sealing ring is 5 to 10 mm.
[0016] Furthermore, a handle 6 is provided on the sealed can lid for easy use.
[0017] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
