Abstract
Description
Technical Field
[0001] This utility model relates to the field of laboratory glassware, and in particular to a pressure-resistant single-row tube device. Background Technology
[0002] In the field of laboratory glassware, single-row tube devices are commonly used gas path control equipment in laboratories and are widely used in chemical synthesis, material preparation and other experimental processes. They are mainly used to realize functions such as gas conduction, diversion and pressure regulation, and are one of the key components to ensure the stable operation of experimental systems.
[0003] Currently, traditional single-row tube devices have significant shortcomings in terms of pressure resistance. Because they mostly use ordinary glass materials or simple sealing structures, when the pressure inside the experimental system increases, problems such as air leakage at the joints and tube rupture are prone to occur. This not only affects the normal conduct of the experiment, but may also cause safety hazards due to gas leakage. This risk is even more prominent in experiments involving flammable, explosive, or toxic gases.
[0004] In addition, the pressure monitoring and pressure relief functions of traditional single-row tube devices are often poorly integrated, and most require additional complex external monitoring instruments and pressure relief equipment. This not only increases the difficulty of assembling the experimental device, but may also further reduce the overall sealing and pressure resistance of the system due to compatibility issues between the external equipment and the single-row tube, making it difficult to meet the requirements of high-precision and high-safety experiments.
[0005] Based on this, we propose a pressure-resistant single-row pipe device. Utility Model Content
[0006] To address the significant shortcomings in pressure resistance of traditional single-row pipe devices, this invention provides a pressure-resistant single-row pipe device.
[0007] This utility model is achieved by the following technical solution: a pressure-resistant single-row pipe device, characterized in that it includes a single-row pipe, the inner diameter of the top end of the single-row pipe is provided with a threaded head, the left end of the single-row pipe is sealed with a PEEK head, one end of the PEEK pipe passes through the inner side of the PEEK head, and the other end of the PEEK pipe is connected to a pressure-resistant bottle.
[0008] During the media transport process, the pressure gauge connected above the first PTFE plug on the inner side of the first branch head can monitor the pressure inside the single-row pipe in real time, so that the operator can keep track of the system pressure status.
[0009] A pressure gauge is connected to the top of the first PTFE plug, and a second PTFE plug is connected to the inside of the second branch. A pressure relief valve is connected to the top of the second PTFE plug. The pressure relief valve can be selected according to different experimental pressure requirements to ensure that the system pressure is always within a safe range. Similarly, the threaded connection and sealing design between the second PTFE plug and the second branch also ensure the stability and sealing performance of the pressure relief process.
[0010] As a further optimization of this utility model, when the device is put into use, the medium inside the pressure-resistant bottle is transported to the inside of the single-row pipe through the PEEK pipe. The PEEK head seals the connection between the PEEK pipe and the single-row pipe, ensuring that no leakage occurs during the transport process. The threaded head on the inner diameter of the top of the single-row pipe can be connected to an external pipeline according to actual needs to achieve further transmission or diversion of the medium.
[0011] As a further optimization of this utility model, a first branch head and a second branch head are connected to the top of the single-row pipe, and the first branch head and the second branch head are integrally formed with the single-row pipe.
[0012] As a further optimization of this utility model, the first branch head and the second branch head are integrally formed with the single-row pipe. This structural design enhances the overall pressure resistance of the device, avoids the problem of reduced pressure resistance caused by unstable connection, and further ensures the stable operation of the device under high pressure environment.
[0013] As a further optimization of this utility model, a first PTFE plug is connected to the inner side of the first branch head, and the first PTFE plug and the first branch head are detachably connected. The outer periphery of the first PTFE plug and the second PTFE plug are provided with external threads, which are adapted to the internal threads on the inner side of the corresponding branch head.
[0014] As a further optimization of this utility model, since the external thread on the outer periphery of the first PTFE plug is compatible with the internal thread on the inner side of the first branch head, and a sealing layer is provided on the connecting surface, the stability of the connection is ensured and the sealing performance at this point is enhanced, thus avoiding the impact of media leakage on monitoring accuracy during pressure monitoring.
[0015] As a further optimization of this utility model, the pressure relief valve can be matched with a suitable pressure relief valve according to the experimental requirements. When the internal pressure of the single-row pipe reaches the preset threshold, the pressure relief valve connected above the second PTFE plug on the inner side of the second branch head will automatically open to relieve pressure.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] 1. This utility model significantly improves the overall sealing performance of the device by using a PEEK head to seal the connection between the PEEK pipe and the single-row pipe, combined with the thread adaptation and sealing layer design of the first PTFE plug, the second PTFE plug and the corresponding branch head. This effectively solves the problem of air leakage at the interface of traditional devices, ensures stable medium transmission under high pressure, and reduces safety hazards.
[0018] 2. This utility model enhances the overall structural strength and pressure resistance by making the first branch head, the second branch head and the single row of pipes into an integrated structure, avoiding the decrease in pressure resistance caused by unstable connection. Compared with the traditional split structure, it can better adapt to high-pressure test scenarios and extend the service life of the device.
[0019] 3. This utility model integrates a pressure gauge and a pressure relief valve. The pressure relief valve can be matched with a suitable pressure relief valve according to the experimental requirements to realize real-time pressure monitoring and on-demand pressure relief without the need for additional external equipment. This simplifies the device assembly process, solves the problems of low functional integration and poor adaptability of traditional equipment, and improves the convenience of experimental operation.
[0020] 4. This utility model features a detachable connection between the first PTFE plug and the first branch head, facilitating the inspection and replacement of the pressure gauge and related components, thus reducing maintenance costs. Simultaneously, the threaded connection design ensures the stability and sealing of the connection after component replacement, balancing practicality and safety. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0025] Example 1:
[0026] Please combine Figure 1This embodiment proposes a pressure-resistant single-row pipe device, characterized by comprising a single-row pipe 1, with a threaded head 2 on the inner diameter of the top end of the single-row pipe 1. A PEEK head 3 is sealed to the left end of the single-row pipe 1, and one end of a PEEK pipe 4 passes through the inner side of the PEEK head 3. The other end of the PEEK pipe 4 is connected to a pressure-resistant bottle. When the device is put into use, the medium in the pressure-resistant bottle is transported to the inside of the single-row pipe 1 through the PEEK pipe 4. The PEEK head 3 seals the connection between the PEEK pipe 4 and the single-row pipe 1, ensuring that the medium does not leak during transportation. The threaded head 2 on the inner diameter of the top end of the single-row pipe 1 can be connected to external pipelines as needed to achieve further transmission or diversion of the medium.
[0027] A first branch head 5 and a second branch head 6 are connected to the top of the single-row pipe 1. The first branch head 5 and the second branch head 6 are integrally formed with the single-row pipe 1. This integrally formed structure enhances the overall pressure resistance of the device, avoids the problem of reduced pressure resistance due to unstable connection, and further ensures the stable operation of the device under high pressure environment.
[0028] The inner side of the first branch head 5 is connected to a first PTFE plug 7, and the connection between the first PTFE plug 7 and the first branch head 5 is detachable. The outer circumferences of the first PTFE plug 7 and the second PTFE plug 9 are provided with external threads, which are adapted to the internal threads on the corresponding branch heads. During media transportation, the pressure gauge 8 connected above the first PTFE plug 7 on the inner side of the first branch head 5 can monitor the pressure inside the single-row pipe 1 in real time, allowing operators to promptly grasp the system pressure status. Because the external threads on the outer circumference of the first PTFE plug 7 are adapted to the internal threads on the inner side of the first branch head 5, and the connection surface is provided with a sealing layer, both the stability of the connection and the sealing performance at this point are enhanced, preventing media leakage during pressure monitoring from affecting the monitoring accuracy.
[0029] A pressure gauge 8 is connected above the first PTFE plug 7, and a second PTFE plug 9 is connected to the inside of the second branch 6. A pressure relief valve 10 is connected above the second PTFE plug 9. The pressure relief valve 10 can be matched with a suitable pressure relief valve according to experimental requirements. When the internal pressure of the single-row pipe 1 reaches a preset threshold, the pressure relief valve 10 connected above the second PTFE plug 9 on the inside of the second branch 6 will automatically open to release pressure. The pressure relief valve 10 can be selected according to different experimental pressure requirements to ensure that the system pressure is always within a safe range. Similarly, the threaded connection and sealing design between the second PTFE plug 9 and the second branch 6 also ensure the stability and sealing performance of the pressure relief process.
[0030] The working principle of this pressure-resistant single-row pipe device is as follows:
[0031] When the device is put into use, the medium in the pressure-resistant bottle is transported to the inside of the single-row pipe 1 through the PEEK pipe 4. The PEEK head 3 seals the connection between the PEEK pipe 4 and the single-row pipe 1, ensuring that the medium does not leak during transportation. The threaded head 2 on the inner diameter of the top of the single-row pipe 1 can be connected to external pipelines as needed to achieve further transmission or diversion of the medium.
[0032] During media transportation, the pressure gauge 8 connected above the first PTFE plug 7 on the inner side of the first branch head 5 can monitor the pressure inside the single-row pipe 1 in real time, so that operators can keep track of the system pressure status. Since the external thread on the outer circumference of the first PTFE plug 7 is compatible with the internal thread on the inner side of the first branch head 5, and the connection surface is provided with a sealing layer, the stability of the connection is ensured and the sealing performance at this point is enhanced, preventing media leakage during pressure monitoring from affecting the monitoring accuracy.
[0033] When the internal pressure of the single-row pipe 1 reaches a preset threshold, the pressure relief valve 10 connected above the second PTFE plug 9 on the inner side of the second branch head 6 will automatically open to relieve pressure. The pressure relief valve 10 can be selected according to different experimental pressure requirements to ensure that the system pressure is always within a safe range. Similarly, the threaded connection and sealing design between the second PTFE plug 9 and the second branch head 6 also ensure the stability and sealing performance of the pressure relief process.
[0034] In addition, the first branch head 5 and the second branch head 6 are integrally formed with the single-row pipe 1. This structural design enhances the overall pressure resistance of the device, avoids the problem of reduced pressure resistance caused by unstable connection, and further ensures the stable operation of the device under high pressure environment.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
