Therefore, those skilled in the art have provided a LPG sampling and mixing device to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned deficiencies and provide a liquefied petroleum gas (LPG) sampling and mixing device. By using a sleeve and a sealing disc, this invention solves the technical problem of difficulty in accurately controlling the filling amount during the sample filling process in the prior art, which leads to deviations in subsequent detection and analysis results and affects the accurate assessment of LPG quality.

[0005] The objective of this utility model is achieved through the following means:

[0006] A liquefied petroleum gas (LPG) sampling and mixing device includes a tank body. A sleeve is sleeved through the bottom of the tank body, and a push rod is sleeved through the bottom of the sleeve. A sealing plate is installed on the top of the push rod. An arc-shaped locking block is installed on the top of the sleeve. A baffle is installed on the outer wall of the sleeve. After multiple samplings, the liquid and gas samples in the tank body can be mixed by reciprocating the pulling of the sleeve, which is beneficial for subsequent detection and analysis. A vent hole is opened at the bottom of the sleeve. An air inlet pipe is installed at the top of the tank body. A pressure gauge is installed on one side of the air inlet pipe. An exhaust pipe is connected to the side wall of the tank body. An arc-shaped locking groove is opened on the inner wall of the top of the tank body.

[0007] Furthermore, a handle is installed on the outer wall of the tank for easy carrying and handling, and corresponding valves are installed on the air inlet pipe and the exhaust pipe, which can control the opening and closing of the pipes.

[0008] Furthermore, the sleeve is slidably fitted with the bottom of the tank, and the top of the sleeve is rotatably engaged with the arc-shaped locking block and the arc-shaped locking groove.

[0009] Furthermore, the push rod and the sleeve are slidably connected, the outer wall of the sealing disc at the top of the push rod is in contact with the inner wall of the sleeve, and the upper side of the sealing disc is in contact with the top side wall of the tank. After opening the valve of the air inlet pipe at the top of the tank, the sample can be filled into the sleeve inside the tank through the air inlet pipe. As the sample is filled, the sealing disc moves the push rod downward under the pressure of the air until the sealing disc contacts the bottom side wall of the sleeve. At this time, a certain amount of sample gas is filled into the sleeve. Then, the sleeve is rotated to disengage the sleeve from the tank, and the push rod is pushed upward again, so that the sealing disc pushes the sample injected into the tank into the sleeve.

[0010] The beneficial effects of this utility model are as follows: This utility model's liquefied petroleum gas sampling and mixing device consists of a tank, a sleeve, and a push rod. A vent hole is provided on the bottom side of the sleeve. The sleeve is engaged with an arc-shaped groove on the top side wall of the tank via an arc-shaped locking block. A sealing disc is connected to the top of the push rod. When the sample is filled, the sealing disc, under air pressure, drives the push rod downwards until it contacts the bottom side wall of the sleeve, thus achieving quantitative filling of the sample gas inside the sleeve and ensuring accurate sampling each time. After rotating the sleeve to disengage it from the tank, pushing the push rod upwards allows the sealing disc to push the quantitatively injected sample from the sleeve into the tank. The operation is simple. Furthermore, after multiple samplings, by repeatedly pulling the sleeve, the baffles on the outer wall of the sleeve can mix the liquid and gas samples inside the tank, making the sample more uniform and beneficial for subsequent testing and analysis.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0017] In this embodiment, refer to Figures 1-4 The liquefied petroleum gas sampling and mixing device specifically implemented includes a tank 1. A handle 5 is installed on the outer wall of the tank 1 for easy carrying and handling. Corresponding valves are installed on the inlet pipe 2 and the exhaust pipe 3, which can control the opening and closing of the pipes. A sleeve 6 is sleeved through the bottom of the tank 1. A push rod 7 is sleeved through the bottom of the sleeve 6. A sealing plate 701 is installed on the top of the push rod 7. An arc-shaped locking block 601 is installed on the top of the sleeve 6. A baffle 602 is installed on the outer wall of the sleeve 6. A vent hole 603 is opened at the bottom of the sleeve 6. An inlet pipe 2 is installed on the top of the tank 1. A pressure gauge 4 is installed on one side of the inlet pipe 2. An exhaust pipe 3 is connected to the side wall of the tank 1. An arc-shaped locking groove 101 is opened on the inner wall of the top of the tank 1.

[0018] Reference Figures 1-4 The sleeve 6 is slidably sleeved with the bottom of the tank 1. The top of the sleeve 6 is rotatably engaged with the arc-shaped slot 101 via the arc-shaped locking block 601. The push rod 7 is slidably sleeved with the sleeve 6. The outer wall of the sealing disc 701 at the top of the push rod 7 is in close contact with the inner wall of the sleeve 6, and the upper side of the sealing disc 701 is in close contact with the top side wall of the tank 1. After opening the valve of the air inlet pipe 2 at the top of the tank 1, the sample can be filled into the sleeve 6 inside the tank 1 through the air inlet pipe 2. As the sample is filled, the sealing disc 701 is squeezed by the air pressure. The push rod 7 moves downward until the sealing disc 701 contacts the bottom side wall of the sleeve 6. At this time, a certain amount of sample gas is filled into the sleeve 6. Then, the sleeve 6 is rotated to disengage it from the tank 1. The push rod 7 is pushed upward again, so that the sealing disc 701 pushes the sleeve 6 to push the quantitatively injected sample into the tank 1. After multiple samplings, the sleeve 6 can be pulled back and forth to mix the liquid and gas samples in the tank 1 by the baffle 602 installed on the outer wall of the sleeve 6, which is beneficial for subsequent detection and analysis.

[0019] This practical internal liquefied petroleum gas sampling and mixing device consists of a tank 1, a sleeve 6, and a push rod 7. An air inlet pipe 2 is connected to the top of the tank 1, and an exhaust pipe 3 is connected to the side wall of the tank 1. Valves are installed on both the exhaust pipe 3 and the air inlet pipe 2. A pressure gauge 4 is also installed on the top of the tank 1. The sleeve 6 is slidably sleeved with the bottom of the tank 1, and a sealing element is installed in the sleeve contact. The push rod 7 is slidably inserted into the bottom of the sleeve 6. A vent hole 603 is opened on the bottom side of the sleeve 6, and an arc-shaped locking block 601 is installed on the upper end of the sleeve 6 inside the tank 1. An arc-shaped locking groove 101 is opened on the inner wall of the top of the tank 1. Rotating the sleeve 6 can cause the top of the sleeve 6 to engage with the arc-shaped locking block 601 and the arc-shaped locking groove 101. A sealing plate 701 is installed on the top of the push rod 7 inside the sleeve 6.

[0020] When the top of the sleeve 6 contacts the top side wall of the tank 1, the sealing disc 701 also contacts the top side wall of the tank 1. Then, the valve of the air inlet pipe 2 at the top of the tank 1 is opened, and the sample is filled into the sleeve 6 inside the tank 1 through the air inlet pipe 2. As the sample is filled, the sealing disc 701 moves the push rod 7 downward under the pressure of the air until the sealing disc 701 contacts the bottom side wall of the sleeve 6. At this time, a certain amount of sample gas is filled into the sleeve 6. Then, the sleeve 6 is rotated to disengage the sleeve 6 from the tank 1, and the push rod 7 is pushed upward again, so that the sealing disc 701 pushes the sleeve 6 with the quantitatively injected sample into the tank 1. After multiple samplings, the sleeve 6 can be pulled back and forth to mix the liquid and gas samples in the tank 1 by the baffle 602 installed on the outer wall of the sleeve 6, which is beneficial for subsequent detection and analysis.
