Detailed Implementation
[0045] The following is in conjunction with the appendix Figure 1-14 The present invention will be described in further detail below.
[0046] Example 1, as Figure 1-8As shown, an adjustable-spacing liquid level gauge measuring cylinder includes a cylinder module 1, a variable-spacing module 3, and a connecting module 2. The connecting module 2 is connected to one end of the cylinder module 1, and the variable-spacing module 3 is connected to the other end of the cylinder module 1. The cylinder module 1 is a hollow tubular container that directly contacts and contains the liquid being measured; the material in contact with the liquid can be metal or non-metal. The variable-spacing module 3 has a hollow structure, ensuring the free passage of the liquid or gas being measured. The material in contact with the liquid can be metal or non-metal, and the corresponding material can withstand the corrosion of the medium, meeting the temperature requirements of the process. Pressure requirements; there can be two variable measurement length modules 3, meaning that the connection points between the two devices both use variable length modules, making the installation and use of the level gauge measuring cylinder convenient; the connection module 2 is a connector between the measuring cylinder and the device being measured, achieving a sealed connection to ensure that the liquid level inside the cylinder is consistent with the liquid level inside the container. Its connection form can be flange, thread, welding, quick coupling, etc.; the cylinder module 1 and the variable measurement distance module 3 are combined to form the main body of the level gauge measuring cylinder. By adjusting the relative displacement between the variable measurement distance module 3 and the cylinder module 1, a measuring cylinder that meets the actual measurement distance requirements can be obtained.
[0047] Example 2, as Figure 1-7 As shown, based on the same concept as in Embodiment 1 above, the adjustable spacing liquid level gauge measuring cylinder: one end of the variable measuring spacing module 3 is connected to the outside of the cylinder module 1 through a fixed bracket 6. The fixed bracket 6 is used to fix the variable measuring spacing 3 to a certain length to prevent the spacing from changing during the assembly process.
[0048] Example 3, as Figure 1-4 , Figure 13 and Figure 14As shown, based on the same concept as Embodiment 2 above, the adjustable-spacing liquid level gauge measuring cylinder: the variable measuring spacing module 3 consists of an adjusting cylinder and a connecting cylinder. The outer wall of the adjusting cylinder or connecting cylinder is provided with graduations, providing clear graduation marks so that users can accurately read and set the required length. The length of the liquid level gauge measuring cylinder is adjusted by the vertical movement of the variable measuring spacing module 3 and the fixed measuring spacing module. This ensures that the adjusting cylinder can be smoothly inserted into the inner cavity of the connecting cylinder, facilitating adjustment of the vertical position of the adjusting cylinder within the connecting cylinder. The other end of the variable measuring spacing module 3 is sleeved on the outside of the other end of the cylinder module 1, or... The other end of the measuring interval module 3 is inserted into the other end of the cylindrical module 1 and sealed by the seal 4. The hollow pipe of the variable measuring interval module 3 is of a different size than the hollow pipe of the cylindrical module 1. The smaller hollow pipe is inserted into the larger hollow pipe. The measuring interval is adjusted by changing the length of the smaller hollow pipe. At this time, the diameters of the variable measuring interval module 3 and the cylindrical module 1 are not the same. During assembly, the seal 4 is used to prevent leakage of the measured medium and ensure safe production. A pressure cap 5 is installed at the end of the cylindrical module 1 away from the connecting module 2. The pressure cap 5 is used to protect the seal between the variable measuring interval module 3 and the cylindrical module 1 and prevent leakage.
[0049] Example 4, as Figure 5 and Figure 6 As shown, based on the same concept as in Embodiment 2 above, the adjustable spacing liquid level gauge measuring cylinder: the variable measuring spacing module 3 is a flexible hose 7, and the other end of the flexible hose 7 is connected to the top or outside of the cylinder module 1. The length of the liquid level gauge measuring cylinder is adjusted by moving the flexible hose 7 in the vertical direction, thereby achieving a measuring cylinder of a specific length by bending the flexible hose 7.
[0050] Example 5, as Figure 8-12 As shown, based on the same concept as in Embodiment 1 above, the adjustable-spacing liquid level gauge measuring cylinder consists of a variable measuring spacing module 3 composed of a sliding flange 4-2 and a fixed flange 4-1 connected together. By changing the position of the sliding flange 4-2 relative to the fixed flange 4-1, a measuring cylinder with a specific measuring spacing can be obtained. Both the sliding flange 4-2 and the fixed flange 4-1 have a medium channel 4-3 at their connection surfaces. The medium channel 4-3 can be a long channel 4-31, a short channel 4-32, a large channel 4-33, or a small channel 4-34, ensuring that the medium will not be blocked due to changes in the installation position of the variable measuring spacing module. A sliding fixing hole 9 is provided on the sliding flange 4-2; a fixing connection hole 10 is provided on the fixed flange 4-1.
[0051] Example a: Select the following for the fixed flange 4-1 Figure 10For the flange shown, select the sliding flange 4-2 as follows: Figure 9 or Figure 11 The flange shown can move a small distance in the measuring distance by sliding the bolt in the sliding fixing hole 9 when the change in the measuring distance is less than the length of the sliding fixing hole 9, thus meeting the requirements for the change in the measuring cylinder flange distance.
[0052] Example b: Select the following for fixed flange 4-1 Figure 10 For the flange shown, select the sliding flange 4-2 as follows: Figure 10 ,or Figure 12 The flange shown can be fixed by bolts to the sliding fixing holes 9 and the fixed connection holes 10 at different positions when the required measurement distance is greater than the length of the sliding fixing hole 9. This allows for a larger range of movement of the measurement distance and meets the requirements for changing the measurement cylinder flange distance.
[0053] Example 6, as Figure 2 As shown, based on the same concept as in Embodiment 3 above, the adjustable spacing liquid level gauge measuring cylinder: cylinder module 1 includes a connecting cylinder 1-1 and a variable spacing cylinder 1-2; the variable spacing cylinder 1-2 is connected to the top of the connecting cylinder 1-1, and the connecting module 2 is connected to the outside end of the connecting cylinder 1-1 in the cylinder module 1.
[0054] The other end of the variable measuring spacing module 3 is sleeved on the outside of the other end of the variable spacing cylinder 1-2 in the cylinder module 1, or inserted into the other end of the variable spacing cylinder 1-2 in the cylinder module 1 and sealed by the seal 4. This structure connects the connecting cylinder 1-1, the variable spacing cylinder 1-2, the variable measuring spacing module 3 and the connecting module 2. The measuring spacing is changed by adjusting the insertion depth of the variable measuring spacing module 3 in the variable spacing cylinder 1-2, and finally the spacing of the level gauge measuring cylinder required by the process is obtained. The seal 4 prevents leakage of the measured medium and ensures safe production. The pressure cap 5 is used to protect the seal between the variable measuring spacing module 3 and the variable spacing cylinder 1-2 in the cylinder module 1 and prevent leakage.
[0055] Example 7, as Figure 3As shown, based on the same concept as in Embodiment Six above, the adjustable-spacing liquid level gauge measuring cylinder: cylinder module 1 further includes a straight-through cylinder 1-3; this structure connects the connecting cylinder 1-1, the variable-spacing cylinder 1-2, the straight-through cylinder 1-3, the connecting module 2, and the variable-spacing measuring module 3, wherein the straight-through cylinder 1-3 is installed between the variable-spacing cylinder 1-2 and the connecting cylinder 1-1, extending the overall length of the cylinder module 1; similarly, the measurement spacing is changed by adjusting the insertion depth of the variable-spacing measuring module 3 in the variable-spacing cylinder 1-2, ultimately obtaining the spacing of the liquid level gauge measuring cylinder required by the process, and the sealing element 4 prevents leakage of the measured medium, ensuring safe production, while the pressure cap 5 is used to protect the sealing between the variable-spacing measuring module 3 and the variable-spacing cylinder 1-2 in the cylinder module 1, preventing leakage.
[0056] Example 8, as Figure 4 As shown, based on the same concept as in Embodiment 7 above, the adjustable-spacing liquid level gauge measuring cylinder: the straight-through cylinder 1-3 is composed of several hollow cylinders 1-31 connected end to end, the number of hollow cylinders 1-31 is N, N≥2; the straight-through cylinder 1-3 composed of several hollow cylinders 1-31 connected end to end is also installed between the variable-spacing cylinder 1-2 and the connecting cylinder 1-1, thereby facilitating the extension of the overall length of the cylinder module 1; similarly, the measurement spacing is changed by adjusting the insertion depth of the variable-spacing module 3 in the variable-spacing cylinder 1-2, and finally the spacing of the liquid level gauge measuring cylinder required by the process is obtained. The sealing element 4 prevents leakage of the measured medium and ensures safe production. The pressure cap 5 is used to protect the sealing between the variable-spacing module 3 and the variable-spacing cylinder 1-2 in the cylinder module 1 to prevent leakage.
[0057] Example 9, as Figure 7 As shown, based on the same concept as in Embodiment 1 above, the adjustable spacing liquid level gauge measuring cylinder can be assembled by placing the variable measuring spacing module 3 at the bottom of the entire measuring cylinder.
[0058] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
