Description

Technical Field

[0001] The invention belongs to the technical field of sealing of heterogeneous combination containers, and in particular relates to a sealing device for a heterogeneous pressure combination container. Background Art

[0002] Pressure vessels are sealed containers that bear gas or liquid pressure internally or externally. In modern industry and scientific research, pressure vessels are widely used in many industries such as chemical industry, petroleum, natural gas, aerospace, etc. The main function of pressure vessels is to safely store and handle high-pressure gas or liquid, so the safety and reliability of their design and manufacturing are crucial. However, containers made of a single material still cannot meet the needs of complex working conditions in certain specific cases. Therefore, researchers and engineers began to explore the combined use of different materials to give full play to their respective advantages. For example, the combination of metal and composite materials can reduce weight and improve corrosion resistance while maintaining the strength of the container. In addition, combining the characteristics of different materials, more efficient sealing devices can be designed to ensure the sealing and safety of the container under high-pressure environments. However, the existing pressure vessel sealing technologies on the market are mostly focused on the design of a single material, and lack in-depth research on the combined application of multiple materials, resulting in safety hazards such as sealing failure and leakage in actual applications.

[0021] In order to ensure the integrity of the sealing ring 7 during long-term use, the sealing ring 7 is made of an integral open-mold pressure-resistant and waterproof material, a groove for the sealing ring 7 is processed on the bottom plane of the loading container 2, and the sealing ring 7 is placed in the groove to form a seamless sealing mechanism; a number of through holes 8 and threaded holes are provided in the loading container 2 and the load object 1, and the sizes and positions of the through holes 8 and threaded holes in the loading container 2 and the load object 1 need to correspond one to one.

[0022] According to a further optimized solution, the high-pressure loading mechanism includes an electric pressure test pump, which is connected to the liquid cavity 3 through a pressure pipe.

[0023] To further optimize the solution, a pressure regulating valve is provided on the electric pressure test pump.

[0024] The electric pressure test pump is a pressure supply device with a pressure regulating valve, and the pressure regulating valve is a component for adjusting the pressure supply power of the electric pressure test pump. The pressure pipe is a water pipe that can withstand high pressure liquid and has negligible deformation, and has the function of connecting the electric pressure test pump and the liquid cavity 3.

[0025] A method for using a sealing device for a heterogeneous pressure combination container comprises the following steps:

[0026] S1. Prepare the load-bearing object 1: Design the component according to its working environment, including factors such as temperature, humidity, and corrosiveness. Clarify the maximum and minimum loads that the component needs to bear;

[0027] Select appropriate materials according to design requirements, such as steel, aluminum alloy, composite materials, etc.;.

[0028] To ensure the good sealing mechanism, the components are subjected to surface treatment as required, such as coating, plating or heat treatment, to improve their corrosion resistance and wear resistance;

[0029] Bolt holes are dug on the pressure-bearing object to ensure the assembly of subsequent connecting devices.

[0030] S2. Preparation of sealing mechanism: The sealing mechanism tightly connects the loading container 2 and the load object 1 so that there is no gap between them as a whole; the sealing mechanism is composed of anchor rods 9 or bolts and nuts and sealing rings 7. In order to ensure the integrity of the sealing ring 7 during long-term use, the sealing ring 7 is made of an integral molded pressure-resistant and waterproof material. A groove for the sealing ring 7 is machined on the bottom plane of the loading container 2, and the sealing ring 7 is placed in the groove to form a seamless sealing device; a plurality of through holes 8 and threaded holes are provided in the loading container 2 and the load object 1, and the sizes and positions of the through holes 8 and threaded holes in the loading container 2 and the load object 1 need to correspond one to one;

[0031] S3. Connect the high-pressure loading mechanism: connect the pressure pipe to the water outlet of the electric pressure test pump, and then fill the water tank of the electric pressure test pump with liquid;

[0032] S4. Conduct the test: connect the power supply of the electric pressure test pump, turn on the switch, start the monitoring system and the electric pressure test pump according to the pressure value required for the test; during the process, adjust the pressure regulating valve according to the pressure value displayed on the pressure gauge, fill the combined container with liquid and pressurize it, and when the pressure value required for the test is reached, turn off the electric pressure test pump, maintain the test pressure value, and maintain the time required for the test.

[0033] There is also a stainless steel loading and stabilizing water cylinder, which is powered by a hydraulic cylinder articulated with it. The hydraulic pressure value collected by the digital pressure transmitter set in the hydraulic system proportionally controls the oil pressure of the hydraulic cylinder, thereby achieving an accurate stabilizing head loading force value. Considering that a large amount of liquid may be required instantaneously when the test reaches cracking, the water tank is connected to an external water pipe and equipped with a liquid level meter for control. When the water level in the water tank is low, the solenoid valve is automatically opened to allow the liquid to enter, so as to always ensure that the water tank is fully stocked with liquid.
