Description

Technical Field

[0001] This utility model relates to the field of pressure testing technology for high-pressure reactors, specifically a high-precision pressure testing device for special equipment. Background Technology

[0002] In modern industrial production, high-pressure reactors are widely used in numerous fields such as chemical engineering, pharmaceuticals, and materials synthesis. They can conduct various chemical reactions under extreme conditions of high temperature and pressure, playing a crucial role in producing high-value-added products and driving the development of new processes. For example, in the chemical industry, high-pressure reactors are commonly used in important production processes such as hydrocracking and ammonia synthesis in petrochemicals. In the pharmaceutical industry, they are used to synthesize certain special drug intermediates. However, the safe operation of high-pressure reactors is paramount. A malfunction, such as an explosion or leak caused by pressure runaway, can cause extremely serious harm to personnel safety, the environment, and company property. Therefore, pressure testing of high-pressure reactors is a necessary means to ensure their safe and reliable operation. Through pressure testing, the pressure resistance, sealing performance, and stability of the pressure control system of the reactor can be accurately detected. However, existing high-pressure reactor pressure testing devices still have some problems in use: First, the inflation head in the existing pressure testing device is generally fixedly installed on the device. Since the shape of the air inlet of different reaction vessels is different, different inflation heads are required when testing different reaction vessels. The fixed installation of the inflation head is not conducive to the replacement of the inflation head, which reduces the convenience of operating the pressure testing device. Secondly, existing testing equipment generally uses manual valves to control the pressure loading rate. The manual method is difficult to adjust precisely, making it difficult to accurately control the pressure changes during the pressure test, thus affecting the accuracy of the pressure test results. Utility Model Content

[0003] To address the problems of inconvenient replacement of the inflation head and difficulty in accurately controlling pressure by manually adjusting the valve in existing pressure testing devices, the purpose of this utility model is to provide a high-precision pressure testing device for special equipment.

[0004] To solve the above technical problems, the present invention adopts the following technical solution: a high-precision special equipment pressure testing device, comprising a base, an air compressor body fixedly mounted on the upper surface of the base, an air outlet pipe connected to one side of the air compressor body, a valve provided on the outer surface of the air outlet pipe, an adjustment mechanism for use with the valve provided on one side of the air compressor body, a conveying pipe connected to one end of the air outlet pipe, an inflation pipe connected to one end of the conveying pipe, an inflation head provided on one side of the inflation pipe, a connecting assembly provided between the inflation pipe and the inflation head, the connecting assembly comprising a first connecting flange, the first connecting flange being fixedly connected to one side of the inflation pipe, a second connecting flange for use with the first connecting flange being fixedly connected to one side of the inflation head, and locking bolts being symmetrically threaded to one side of the first connecting flange and the second connecting flange.

[0005] Preferably, the adjusting mechanism includes a support shell, which is fixedly installed on one side of the air compressor body. A cylinder is fixedly installed on the upper surface of the support shell, and a moving plate is fixedly connected to the output end of the cylinder. A rack is fixedly connected to the lower surface of the moving plate through the support shell. A round rod is fixedly connected to the upper surface of the valve, and a gear is fixedly sleeved on the outer surface of the round rod. The gear meshes with the rack.

[0006] Compared with the prior art, the beneficial effects of this utility model are as follows: This application provides a connecting component between the gas filling pipe and the gas filling head, which facilitates the flexible and quick replacement of the appropriate gas filling head according to the actual test reactor conditions. The appropriate gas filling head is more conducive to pressure detection, thereby improving the ease of operation of the pressure testing device. 2.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Example: Figure 1-4 As shown, this utility model provides a high-precision pressure testing device for special equipment, including a base 1. An air compressor body 4 is fixedly installed on the upper surface of the base 1. An air outlet pipe 5 is connected to one side of the air compressor body 4. Compressed air generated by the air compressor body 4 is transported through the air outlet pipe 5. A valve 9 is provided on the outer surface of the air outlet pipe 5. The valve 9 can control the flow and cut-off of compressed air in the air outlet pipe 5. An adjustment mechanism 3 is provided on one side of the air compressor body 4 to cooperate with the valve 9. The adjustment mechanism 3 can precisely control the opening and closing degree of the valve 9. Compared with manually operating the valve 9, it can more accurately control the flow and pressure of compressed air, improve the accuracy and stability of pressure test results, and meet the requirements of high-precision special equipment pressure testing for precise pressure control.

[0015] The upper surface of the air outlet pipe 5 is provided with a pressure gauge body 10, which displays the pressure value inside the air outlet pipe 5 in real time, allowing the operator to intuitively understand the current pressure situation. One end of the air outlet pipe 5 is connected to a delivery pipe 8, which is a flexible hose of sufficient length. The delivery pipe 8 serves as a channel connecting the air outlet pipe 5 and the inflation pipe 6. Its flexible nature allows for flexible arrangement of pipelines in different testing environments. One end of the delivery pipe 8 is connected to an inflation pipe 6, and an inflation head 7 is provided on one side of the inflation pipe 6. The inflation pipe 6 and the inflation head 7 deliver compressed air to high-precision special equipment for pressure testing. A connecting component 2 is provided between the inflation pipe 6 and the inflation head 7. The connecting component 2 facilitates flexible and quick replacement of the appropriate inflation head 7 according to the air inlet conditions of different high-precision special equipment, improving the ease of operation of the pressure testing device.

[0016] The connecting assembly 2 includes a first connecting flange 26, which is fixedly connected to one side of the inflation tube 6. A second connecting flange 29, which is used in conjunction with the first connecting flange 26, is fixedly connected to one side of the inflation head 7. Locking bolts 24 are symmetrically threaded onto one side of the first connecting flange 26 and the second connecting flange 29. Through the cooperation of the first connecting flange 26, the second connecting flange 29 and the locking bolts 24, a detachable connection between the inflation tube 6 and the inflation head 7 is achieved. When it is necessary to replace different types of inflation heads 7, it is easy to disassemble and replace them by simply unscrewing the locking bolts 24. The operation is simple and convenient. A first screw hole 21 and a second screw hole 201, which are used in conjunction with the locking bolts 24, are respectively provided on one side of the first connecting flange 26 and the second connecting flange 29. The locking bolts 24 are threadedly connected to the first screw hole 21 and the second screw hole 201, which provide accurate connection positions for the locking bolts 24.

[0017] A positioning rod 28 is fixedly connected to one side of the second connecting flange 29 in an annular array. A positioning groove 23 is opened on one side of the first connecting flange 26 in an annular array to cooperate with the positioning rod 28. The positioning rod 28 and the positioning groove 23 are movably inserted into each other. The cooperation between the positioning rod 28 and the positioning groove 23 plays a role in precise positioning when installing the inflation head 7, ensuring that the screw holes on the first connecting flange 26 and the second connecting flange 29 are accurately aligned, which facilitates the installation of the locking bolt 24.

[0018] The first connecting flange 26 and the second connecting flange 29 are respectively provided with a first annular groove 25 and a second annular groove 202 at one end of their opposite faces. A first rubber ring 22 and a second rubber ring 27 are respectively fixedly installed in the first annular groove 25 and the second annular groove 202. The first rubber ring 22 and the second rubber ring 27 play a good sealing role, preventing compressed air from leaking at the connection and ensuring the accuracy of the pressure test.

[0019] The adjustment mechanism 3 includes a support shell 37, which is fixedly installed on one side of the air compressor body 4. A cylinder 34 is fixedly installed on the upper surface of the support shell 37, and a movable plate 35 is fixedly connected to the output end of the cylinder 34, so that the output end of the cylinder 34 can push the movable plate 35 to slide. A guide groove 36 is provided on the upper surface of the support shell 37 to cooperate with the movable plate 35. The movable plate 35 is slidably connected to the guide groove 36. The guide groove 36 plays a role in guiding and limiting the movement of the movable plate 35, ensuring the stability and accuracy of the movement of the movable plate 35.

[0020] The lower surface of the movable plate 35 penetrates the support shell 37 and is fixedly connected to a rack 31. The movement of the movable plate 35 drives the rack 31 to move. The upper surface of the valve 9 is fixedly connected to a round rod 33, and a gear 32 is fixedly sleeved on the outer surface of the round rod 33. The gear 32 meshes with the rack 31. Because the gear 32 meshes with the rack 31, the gear 32 will rotate as the rack 31 moves, thereby driving the round rod 33 and the valve 9 to rotate, realizing precise control of the opening and closing degree of the valve 9. It can accurately adjust the flow rate and pressure of compressed air according to the needs of pressure testing, and improve the accuracy of pressure test results.

[0021] Working principle: First, select the appropriate inflation head 7 and install it through the connecting component 2. During connection, the positioning rods 28 of the annular array on one side of the second connecting flange 29 are inserted into the positioning grooves 23 of the annular array on one side of the first connecting flange 26, which plays a role in precise positioning and ensures that the screw holes on the first connecting flange 26 and the second connecting flange 29 are accurately aligned.

[0022] Then, by passing the locking bolt 24 through the first screw hole 21 and the second screw hole 201 and tightening it with threads, a firm connection is achieved between the air inlet tube 6 and the air inlet head 7. At the same time, the first rubber ring 22 and the second rubber ring 27 play a sealing role after connection to prevent compressed air from leaking at the connection. This installation method improves the ease of operation of the pressure testing device.

[0023] After the air inlet 7 is connected, connect it to the air inlet of the reactor.

[0024] Then, start the air compressor body 4. Compressed air is output from one side of the air compressor body 4 through the air outlet pipe 5. At this time, the valve 9 is in the closed state to prevent gas leakage.

[0025] When preparing for a pressure test, the opening and closing of valve 9 is controlled by adjusting mechanism 3. Cylinder 34 is activated, and the output end of cylinder 34 pushes the movable plate 35 fixedly connected to it. The movable plate 35 slides in the guide groove 36. The guide groove 36 guides and limits the movement of the movable plate 35, ensuring smooth and precise movement. The movement of movable plate 35 drives rack 31 to move, rack 31 drives gear 32 to rotate, gear 32 rotates, rod 33 rotates, and rod 33 rotates, which in turn drives valve 9 to rotate, thereby achieving precise control of the opening and closing degree of valve 9, and thus regulating the flow rate and pressure of compressed air in outlet pipe 5.

[0026] After adjustment, the compressed air enters the delivery pipe 8 from one end of the outlet pipe 5. The gas in the delivery pipe 8 is smoothly delivered to the inflation pipe 6. The compressed air in the inflation pipe 6 enters the special equipment through the inflation head 7 for pressure testing.

[0027] During this process, the pressure gauge body 10 on the upper surface of the vent pipe 5 displays the pressure value inside the pipe in real time. The operator can judge the current pressure status based on this value and complete the pressure test of the high-precision special equipment.

[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
