[0002] In the prior art, a liquefied gas sampling and analysis device is disclosed in the utility model with the application number 20222237393.4. In order to solve the problem that when the heating and insulation belt heats the vaporization container, if the external temperature is relatively low, part of the heat heated by the heating and insulation belt is likely to be lost, thus reducing the heating effect and making it difficult for the liquefied gas to be quickly and completely vaporized, which brings inconvenience to sampling and analysis. By setting fastening bolts, fixing plates, fastening plates, mounting shells, felt bodies and heat insulation layers, the fastening bolts pass through the fastening plates and the fixing plates, so that the fixing plates and the fastening plates are fixed, realizing the function of fastening the mounting shell. Thus, the inner side of the felt body can closely adhere to the outer side of the heating and insulation belt main body, the mounting shell wraps the heating and insulation belt main body, and the heat insulation layer and the felt body play a role in heat insulation, making the heat during the heating of the heating and insulation belt main body not easily lost, so as to enable the heating and insulation belt main body to quickly heat the vaporization container main body, improving the heating effect and causing the liquefied gas to be quickly and completely vaporized.

The protection main body composed of a front sleeve and a rear sleeve is slidably connected between the front sleeve and the rear sleeve, which can be automatically adjusted according to the length of the vaporization container during use, improving the applicability of the device. In addition, annular air bags are arranged at the ends of the front sleeve and the rear sleeve, and are used in cooperation with the inflation mechanism composed of an arc-shaped clamping sleeve, a rubber ring and an internal screw pipe, so that the vaporization container can have a better sealing effect, reducing heat loss. By evenly arranging heat conduction plates along the circumferential direction on the side of the vaporization container, and the heat conduction plates all penetrate the vaporization container, the contact area with the liquefied gas can be increased during heating, improving the heating rate and effect.

[0021] To make the technical solutions of the present utility model clearer and more definite for those skilled in the art, the present utility model will be further described in detail below with reference to the embodiments and the accompanying drawings, but the embodiments of the present utility model are not limited thereto.

[0022] As Figures 1 - 3 shown, this embodiment provides a liquefied gas sampling and analysis device, including a vaporization container 1 and a heating and heat preservation belt 3 wrapped outside the vaporization container 1. A front sleeve 4 is sleeved at one end outside the vaporization container 1, and a rear sleeve 5 is sleeved at the other end outside the vaporization container 1. The front sleeve 4 and the rear sleeve 5 are slidably connected, and annular airbags 6 are provided at the inner ends of the front sleeve 4 and the rear sleeve 5. Inflating mechanisms are provided on the outer sides of the front sleeve 4 and the rear sleeve 5.

[0023] Overall working principle: After extracting and storing the liquefied gas sample inside the vaporization container 1, due to the different sizes of the selected vaporization container 1, then adjust the lengths of the front sleeve 4 and the rear sleeve 5 to ensure that the side of the vaporization container 1 can be completely wrapped. Then wrap the heating and heat preservation belt 3 outside the vaporization container 1 to heat the vaporization container 1 to ensure that the internal sample is completely vaporized. Finally, the vaporization container 1 passes through the inside of the front sleeve 4 and the rear sleeve 5. At this time, the annular airbags 6 on the front sleeve 4 and the rear sleeve 5 are located at both ends of the vaporization container 1. Use the inflating mechanism to inflate the inside of the annular airbags 6 to ensure the sealing inside the front sleeve 4 and the rear sleeve 5 and reduce the heat loss.

[0024] In this embodiment, heat conducting plates 2 are uniformly arranged along the circumference outside the vaporization container 1. The heat conducting plates 2 penetrate through the vaporization container 1, and the outer ends of the heat conducting plates 2 are attached to the inner wall of the heating and heat preservation belt 3.

[0025] Local working principle: The setting of the heat conducting plates 2 increases the contact area with the heat source, improves the heating and vaporization effect and rate of the liquefied gas, and has higher practicability.

The end of the front sleeve 4 is sleeved on the end of the rear sleeve 5. A slider 13 is slidably installed inside the strip-shaped groove 12, and the slider 13 is fixed on the inner wall of the front sleeve 4.

[0027] Local working principle: Due to the arrangement of the strip-shaped grooves 12 and the sliders 13, the separation between the front sleeve 4 and the rear sleeve 5 can be avoided, ensuring the stability of the connection.

[0028] In this embodiment, a sealing ring is fixed at one end of the rear sleeve 5 located inside the front sleeve 4, and the outer side of the sealing ring is attached to the inner wall of the front sleeve 4.

[0029] Local working principle: The arrangement of the sealing ring ensures the sealing effect at the joint between the rear sleeve 5 and the front sleeve 4, preventing hot air from leaking.

[0030] In this embodiment, the inflation mechanism includes an arc-shaped clamping sleeve 8, a rubber ring 9, an internal screw tube 10, and air holes 11. The arc-shaped clamping sleeve 8 is fixed at the ends of the front sleeve 4 and the rear sleeve 5. A rubber ring 9 is slidably arranged inside the arc-shaped clamping sleeve 8. Air holes 11 communicating with the inside of the arc-shaped clamping sleeve 8 are formed on both the front sleeve 4 and the rear sleeve 5. Internal screw tubes 10 are threadedly installed at the ends of the front sleeve 4 and the rear sleeve 5, and the ends of the internal screw tubes 10 are attached to the outer sides of the rubber rings 9.

[0031] Local working principle: During the inflation process, the internal screw tube 10 is rotated to squeeze the rubber ring 9, and the gas inside the arc-shaped clamping sleeve 8 is introduced into the internal of the annular airbag 6 through the air holes 11, ensuring the fitting effect between the inner side of the annular airbag 6 and the vaporization container 1.

[0032] In this embodiment, a handle 7 is fixed at one end of the outer side of the front sleeve 4 close to the rear sleeve 5, and the shape of the handle 7 is a U-shaped.

[0033] Local working principle: With the design of the handle 7, it is convenient to carry and move, making the use more convenient.
