Description

Technical Field

[0001] The invention belongs to the technical field of metal empty O-ring high-pressure gas filling, and specifically refers to a metal empty O-ring high-pressure gas filling device. Background Art

[0002] In the modern industrial system, metal O-rings, as important sealing components, are widely used in many fields such as petrochemical, aerospace, energy and electricity. The working environment of these industries is often accompanied by extreme conditions such as high temperature and high pressure, which puts extremely high demands on the sealing performance of metal O-rings.

[0003] When metal empty O-rings are in a high temperature and high pressure environment, the physical properties of the metal material will change significantly. High temperature will intensify the thermal vibration of the metal lattice structure, causing the bonding force between metal atoms to weaken, thereby causing the metal to soften. At the same time, high pressure will further increase the degree of deformation of the metal, causing the original tight sealing structure of the O-ring to be destroyed and the sealing performance to drop significantly. Once a leak occurs, it may not only lead to production interruption and damage to product quality, but may also cause serious safety accidents, such as explosions and fires, posing a huge threat to the safety of human life and property.

[0004] At present, although there are many types of metal empty O-rings on the market, most of them lack effective compensation mechanisms when dealing with high temperature and high pressure working conditions. The traditional design and manufacturing processes cannot fundamentally solve the sealing failure problem caused by the softening of metal under high temperature and high pressure. What is more serious is that in terms of the pressurized manufacturing process of metal empty O-rings, the country is still in a blank state and cannot achieve mass production of pressurized metal empty O-rings. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a metal empty O-ring high-pressure gas filling equipment, which effectively solves the problem that metal empty O-rings lack an effective compensation mechanism when dealing with high temperature and high pressure conditions and cannot achieve mass production of pressurized metal empty O-rings.

[0006] In order to achieve the above functions, the technical solution adopted by the present invention is as follows: a metal empty O-ring high-pressure gas filling device, comprising a box body, a three-axis adjustable working platform is arranged at the bottom of the box body, an O-ring is placed on the three-axis adjustable working platform, an air inlet pipe is connected to the top of the box body, and one end of the air inlet pipe is connected to a charging regulating device to charge gas into the box body;

[0007] The O-ring is provided with a defect, and a welding gun is also provided in the box body, and the defect on the O-ring is welded after the gas is filled.

[0008] Preferably, an observation port is provided on the top of the box body, and the observation port is made of a transparent material with high strength, high temperature resistance and high pressure resistance.

[0009] Preferably, the top of the box body is also connected to an air outlet pipe, and regulating valves are provided on the air inlet pipe and the air outlet pipe.

[0010] Preferably, the welding gun performs welding by one of laser welding and argon arc welding.

[0011] Preferably, the three-axis adjustable working platform fixes the metal hollow O-ring through a hydraulic self-locking structure.

[0012] Preferably, the box body is a sealed box body and is made of high-strength alloy steel, and the box body is sealed by a liquid or gas self-locking device.

[0013] The present invention adopts the above structure to achieve the following beneficial effects:

[0014] 1. The type and pressure of the gas charged are precisely controlled by the charging regulating device. Under high temperature and high pressure environment, the charged gas can effectively compensate for the softening of the metal. When the metal softens due to high temperature, the internal gas pressure can support the O-ring to maintain its shape and maintain the integrity of the sealing structure, which significantly improves the sealing performance and reliability of the O-ring under extreme conditions and ensures that the industrial system can operate stably and safely.

[0015] 2. During the filling and welding process of empty metal O-rings, the hydraulic self-locking structure greatly saves the time of positioning and clamping. It has high stability and reliability, and can always keep the correct position of the workpiece during the entire production process, avoiding production errors and rework caused by workpiece displacement. This series of advantages has greatly improved production efficiency, effectively reduced production costs, and improved the company's market competitiveness. When multiple O-rings need to be processed continuously, the hydraulic self-locking structure can greatly shorten the preparation time of each O-ring, thereby increasing the number of O-rings that can be processed per unit time, directly improving production efficiency.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. The present invention is further described in detail below in conjunction with the accompanying drawings.

[0021] like Figure 1-2 As shown, a metal empty O-ring high-pressure gas filling device proposed by the present invention includes a box body 1, which is a sealed box body 1 and is made of high-strength alloy steel. The box body 1 is sealed by a liquid or gas self-locking device to prevent leakage of high-pressure gas. A three-axis adjustable working platform 2 is arranged at the bottom of the box body 1, and an O-ring 3 is placed on the three-axis adjustable working platform 2. The three-axis adjustable working platform 2 fixes the metal empty O-ring 3 through a hydraulic self-locking structure to improve production efficiency. An air intake pipe 4 is connected to the top of the box body 1, and one end of the air intake pipe 4 is connected to a charging adjustment device 5 to fill gas into the box body 1; a defect 6 is opened on the O-ring 3, and a welding gun 7 is also arranged in the box body 1. After the gas filling is completed, the defect 6 on the O-ring 3 is welded, and the welding gun 7 performs welding by one of laser welding or argon arc welding.

[0022] like Figure 1 As shown, an observation port 8 is provided on the top of the box 1. The observation port 8 is made of a high-strength, high-temperature-resistant, high-pressure-resistant transparent material with good optical and mechanical properties. The surface of the observation port 8 is coated with a special photochromic coating, which can automatically adjust the transmittance according to the light intensity to achieve an automatic shading function, effectively protecting the operator's eyes from strong light damage. An outlet pipe 9 is also connected to the top of the box 1, and regulating valves 10 are provided on the air inlet pipe 4 and the air outlet pipe 9 to adjust the flow rate and switch of the gas to ensure that the pressure in the box 1 meets the requirements.

[0023] When in use, first, use high-precision processing equipment to open a hole of suitable diameter on the metal hollow O-ring 3. The size and position of this hole need to be accurately designed according to the specifications of the O-ring 3, the gas filling amount and the requirements of the subsequent welding process. The O-ring 3 with the hole opened is carefully placed on the three-axis adjustable working platform 2 in the box 1, and the box 1 is sealed. The three-axis adjustable working platform 2 has high-precision positioning capabilities, and its movement accuracy in the X, Y, and Z axis directions can reach ±0.01mm. Through the control interface of the operating platform, set the initial position of the O-ring 3 on the platform to ensure that it is in the subsequent filling and During the welding process, it can accurately move to the designated position. At the same time, the specific gas type and pressure value to be filled are set through the inflation adjustment device 5. The inflation adjustment device 5 is equipped with a high-precision gas flow controller and a pressure sensor, which can accurately control the gas filling amount and pressure. The operator can input the corresponding gas type, pressure, filling time and other parameters on the control interface according to different O-ring 3 specifications and usage scenarios. The inflation adjustment device 5 will inflate according to the set parameters, and through the regulating valve 10, ensure that the output gas pressure is stable near the set value, and the high-pressure gas is delivered to the box body 1 through the air inlet pipe 4;

[0024] During the filling process, the gas pressure in the box body 1 will gradually increase, and the gas will enter the O-ring 3 through the holes. The inflation regulating device 5 will monitor the change of the gas pressure in real time and feed back the data to the control system of the equipment. The control system will adjust the gas flow controller in the inflation regulating device 5 in real time according to the preset pressure value and filling time. At the same time, the operator can observe the filling situation in real time through the observation port. When the gas pressure in the box body 1 reaches the preset value, the inflation regulating device 5 will automatically close the inflation valve and stop inflation.

[0025] After the filling is completed, the three-axis adjustable work platform 2 drives the O-ring 3 to move precisely to the welding position by precisely controlling the movement of the X, Y, and Z axes according to the preset program, and the welding gun 7 welds and seals the opening of the O-ring 3 to complete the filling of the O-ring 3. After the welding is completed, the O-ring 3 can be taken out.

[0026] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
