[0020] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.
[0021] Reference Figures 1 to 3The utility model discloses a gas phase pipe structure of a pressure vessel, wherein the pressure vessel 1 includes a straight section 10, an upper head 11 sealed at the upper end of the straight section 10, and a lower head 12 sealed at the lower end of the straight section 10. The pressure vessel 1 is also provided with a channel for loading and unloading a medium (not shown). This embodiment focuses on the gas phase pipe structure of the pressure vessel, that is, the exhaust pipe structure of the pressure vessel 1.
[0022] Reference Figure 1 The gas phase pipe structure of the pressure vessel 1 includes a pipe body 2, which is divided into an inner pipe section 20 located inside the pressure vessel 1 and an outer pipe section 23 located outside the pressure vessel 1. The inner pipe section 20 and the outer pipe section 23 are connected through a pipe joint installed on the shell of the pressure vessel 1, wherein the pipe joint is installed on the lower side wall of the straight tube section 10, that is, the pipe body 2 is finally passed through the straight tube section 10 close to the side of the lower head 12.
[0023] The inner pipe section 20 is connected to the inner wall of the pressure vessel 1 through a plurality of support structures 21. Figure 1 The support structure 21 includes a sleeve 211 sleeved on the inner pipe section 20, and the sleeve 211 is welded to the inner wall of the pressure vessel 1 through the connecting ear 210; the inner pipe section 20 is inserted into the sleeve 211, so that the inner pipe section 20 adopts a movable support structure. When low\high temperature (pressure) gas enters the pipeline body 2, the inner pipe section 20 can freely expand and contract due to the change in temperature difference, thereby reducing the local stress increased by the support constraint and extending the service life of the emptying pipeline.
[0024] In addition, the upper end of the inner pipe section 20 extends to the inner top of the upper head 11 and is located on the central axis of the pressure vessel 1 , and the upper end of the inner pipe section 20 is welded to the inner top of the pressure vessel 1 .
[0025] Reference Figure 1 A safety valve 3 and a pressure gauge 4 are provided on the outer pipe section 23, wherein the safety valve 3 and the pressure gauge 4 are both installed on the outer pipe section 23 through a reducing joint, and instrument valves that can be opened and closed independently are provided on the pipelines of the safety valve 3 and the pressure gauge 4, so as to facilitate the closure of the pipelines of the safety valve 3 and the pressure gauge 4 during the disassembly and maintenance.
[0026] Reference Figure 2 and Figure 3In one embodiment, a plurality of air inlets 22 are provided on the side wall of the upper end of the inner pipe section 20. During the exhaust process, the gas in the pressure vessel 1 enters the pipe body 2 along the air inlets 22, wherein the plurality of air inlets 22 are evenly arranged around the axis of the inner pipe section 20, and each group of air inlets 22 are long holes extending along the axis of the inner pipe section 20. Therefore, the gas in the top space of the pressure vessel 1 enters the inner pipe section 20 from the long holes in multiple directions and evenly disperses to form a plurality of uniform flows, and the airflow will not form a vortex. When evacuating, the gas will not form a screaming noise to generate sound pollution, and the operation will be more environmentally friendly. In addition, no impact fluid will be generated, so that the reading of the pressure gauge 4 is stable.
[0027] In the gas phase pipe structure of the pressure vessel 1 of the utility model, the three pipes of the exhaust pipe, the safety valve 3 connecting pipe and the pressure gauge 4 connecting pipe are integrated into one, which simplifies the manufacturing process and saves material and labor costs. Therefore, the openings on the pressure vessel 1 are reduced to one hole, reducing the potential leakage points of the pressure vessel 1, reducing the leakage risk, and making the use of the pressure vessel 1 safer and extending the service life. In addition, the outer pipe section 23 is arranged at the lower part of the pressure vessel 1, and the calibration and disassembly operations of the safety valve 3 and the pressure gauge 4 are convenient, reducing the risk of safety accidents caused by high-altitude operations.
[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
