Abstract
Description
Technical Field
[0001] The utility model relates to a buffer device, in particular to a novel multi-section spiral pressure buffer device. Background Art
[0002] In industrial production and various pressure measurement applications, accurately measuring pressure and protecting the reliability of measurement equipment are crucial. Traditional pressure measurement devices often have difficulties in coping with pressure fluctuations, which can lead to inaccurate pressure gauge readings, shortened service life, and equipment failure.
[0003] Common pressure buffering methods may simply rely on straight pipe connections or a single buffer structure, which cannot effectively cope with complex pressure fluctuations. For example, when faced with transient high pressure or frequent pressure fluctuations, straight pipe connections cannot fully absorb and buffer pressure shocks, easily damaging the pressure gauge and affecting its measurement accuracy and stability. A single buffer structure may have limitations in material selection or structural design, and cannot simultaneously ensure pressure resistance, wear resistance, and good elastic buffering performance.
[0004] In addition, traditional pressure buffer devices may also be inconvenient in installation and maintenance. The connections between components are not stable enough, and leakage and other problems may easily occur, affecting the performance and safety of the entire system. Utility Model Content
[0005] In order to solve the above problems, the following technical solutions are proposed:
[0006] A new multi-section spiral pressure buffer device includes an air pipe and a pressure gauge arranged on the air pipe. The pressure gauge is installed on the air pipe through a buffer base. It also includes a buffer device. The buffer device includes a buffer tube. The buffer tube is a multi-section spiral tube. The two ends of the buffer tube are respectively connected to the pressure gauge and the air pipe. The pressure gauge and the air pipe are connected through the buffer tube. The buffer tube is made of a multi-layer composite material, the inner layer is an elastic pressure-resistant layer, the middle layer is a metal reinforcement layer, and the outer layer is a wear-resistant protective layer.
[0007] Furthermore, it also includes a support tube, which is a hollow cylindrical tube and has an outer diameter that is the same as the inner diameter of the spiral buffer tube. The buffer tube is sleeved outside the support tube, and the inner wall of the support tube is provided with evenly distributed buffer protrusions, which are hemispherical.
[0008] Furthermore, one end of the support tube is connected to the mounting sleeve through a thread, the bottom of the mounting sleeve is installed on the buffer base through a connecting seat, the other end of the support tube is sleeved in the support sleeve, the support sleeve is installed on the sliding sleeve through a connecting seat, the sliding sleeve is sleeved on the trachea, the sliding sleeve can slide on the trachea, and sealing gaskets are provided on the inner sides of the mounting sleeve and the support sleeve.
[0009] Furthermore, one end of the buffer tube is mounted on the buffer base through a mounting nut, and an anti-slip groove is provided on the outer side of the mounting nut.
[0010] The beneficial effects of the utility model are as follows:
[0011] The unique multi-section spiral tubular buffer tube and the multi-layer composite material inside can effectively slow down pressure fluctuations, making the pressure transmitted to the pressure gauge more stable, thereby significantly improving measurement accuracy.
[0012] The buffer tube's middle metal reinforcement layer and outer wear-resistant protective layer increase the structural strength and durability of the entire device, reducing equipment failures caused by pressure shock and external wear.
[0013] The optimized design of the buffer device and the use of high-quality materials can reduce pressure damage to the pressure gauge and other components, extending the overall service life of the equipment.
[0014] One end of the buffer tube is installed on the buffer base through a mounting nut with anti-slip grooves, which facilitates installation and disassembly. At the same time, the reasonable connection structure between the various components also makes maintenance work more convenient.
[0015] The sealing gaskets inside the mounting sleeve and the support sleeve effectively prevent pressure leakage, ensuring the stability of the system and the accuracy of measurement.

[0022] The present invention will be further described below with reference to the accompanying drawings:
[0023] A novel multi-segment spiral pressure buffer device comprises an air pipe 1 and a pressure gauge 3 mounted on the air pipe 1. The pressure gauge 3 is mounted on the air pipe 1 via a buffer base 21. The device also comprises a buffer device, which includes a buffer tube 22. The buffer tube 22 is a multi-segment spiral tube. The pressure gauge 3 and the air pipe 1 are connected at both ends of the buffer tube 22, respectively. The buffer tube 22 connects the pressure gauge 3 and the air pipe 1. The buffer tube 22 is made of a multi-layer composite material, with an inner elastic pressure-resistant layer, a middle metal reinforcement layer, and an outer wear-resistant protective layer. The device also comprises a support tube 5. The support tube 5 is a hollow cylindrical tube with an outer diameter equal to the inner diameter of the spiral buffer tube 22. The buffer tube 22 is sleeved on the outside of the support tube 5. The inner wall of the support tube 5 is provided with evenly distributed hemispherical buffer protrusions. One end of the support tube 5 is threadedly connected to the mounting sleeve 41. The bottom of the mounting sleeve 41 is mounted on the buffer base 21 via a connecting seat 43. The other end of the support tube 5 is sleeved within the support sleeve 42. The support sleeve 42 is mounted on a sliding sleeve 421 via a connecting seat 43. The sliding sleeve 421 is sleeved on the trachea 1 and can slide on the trachea 1. The inner sides of both the mounting sleeve 41 and the support sleeve 42 are equipped with sealing washers. One end of the buffer tube 22 is mounted on the buffer base 21 via a mounting nut 221. The outer side of the mounting nut 221 is provided with anti-slip grooves.
[0024] The working principle of this utility model is as follows:
[0025] During operation of this pressure buffer device, when pressure is transmitted from the air pipe 1, it first encounters the multi-section, spiral-shaped buffer tube 22. Due to the unique spiral structure of the buffer tube 22, the pressure path within the tube becomes tortuous, thereby prolonging the pressure transmission time and initially mitigating the pressure impact. Simultaneously, the multi-layer composite material of the buffer tube 22 takes effect. The inner elastic pressure-resistant layer quickly absorbs the pressure energy and buffers the pressure through its own elastic deformation. The middle metal reinforcement layer provides structural support, preventing excessive deformation of the buffer tube 22 under high pressure. The outer wear-resistant protective layer protects the buffer tube 22 from wear and erosion by the external environment.
[0026] The support tube 5 sleeved on the outside of the buffer tube 22 also plays an important auxiliary buffering role. The evenly distributed hemispherical buffering protrusions on the inner wall of the support tube 5 disperse and refract the pressure when it passes through, further reducing the impact of the pressure.
[0027] One end of the support tube 5 is threadedly connected to a mounting sleeve 41, which is securely mounted on the buffer base 21 via a connector 43, ensuring stability at this end. The other end is sheathed within a support sleeve 42, which is in turn mounted on a slidable sleeve 421 via a connector 43. Sleeve 421 slides over the trachea 1. This design allows the entire device to adapt to pressure changes and mitigates stress concentration caused by rigid connections between components.
[0028] When installing or removing the buffer tube 22, the operator can easily do so with the help of the anti-slip grooves on the outside of the mounting nut 221. The sealing gaskets on the inside of the mounting sleeve 41 and the support sleeve 42 form a good seal at the connection between the components, preventing pressure leakage and ensuring accurate pressure transmission and measurement.
[0029] In practice, various embodiments are possible. For example, the number of turns, length, and diameter of the buffer tube 22, as well as the length of the support tube 5 and the density of the buffer protrusions, can be adjusted to suit different pressure ranges and measurement accuracy requirements. Furthermore, multi-layer composite materials with varying properties can be selected to meet specific requirements for corrosion resistance, high-temperature resistance, and other requirements for different operating environments.
[0030] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements shall fall within the scope of the present invention as claimed.
