Description

Technical Field

[0001] This utility model relates to the field of liquid level gauge technology, specifically to a segmented liquid level gauge. Background Technology

[0002] With the development of the chemical industry, tanks of various materials and volumes are ubiquitous in every corner of chemical processes. To meet the needs of operators for observing liquid levels in these tanks, various types of level gauges have been developed. The latest developments include capacitive level gauges and radar level lights, which detect liquid level height using capacitance difference or radar waves. While capacitive and radar level gauges are superior to traditional level gauges in terms of non-contact measurement and pressure and corrosion resistance, they have significant drawbacks such as media dependence, weak anti-interference ability, and high cost. Therefore, to stabilize liquid level detection and reduce costs, current methods for measuring tank liquid levels... Most still use conventional level gauges; conventional level gauges include magnetic level gauges, float level gauges, glass tube level gauges, and weighted level gauges. For example, Chinese Patent 201721456003.1 discloses a combined magnetic level gauge, which includes an outer cylinder assembly, a magnetic float disposed in the outer cylinder assembly, and a magnetic level gauge connected to the outside of the outer cylinder assembly. The inner wall of the outer cylinder assembly and the outer wall of the magnetic float are provided with a composite anti-stick coating. The outer cylinder assembly is composed of multiple cylinder sections connected by flanges.

[0003] For the aforementioned existing technologies, whether it is a traditional single-stage level gauge or the combined level gauge mentioned above, when the height of the container being measured is high (more than 3 meters), due to the two-end connection at the upper and lower ends, the long level gauge itself has considerable weight. When there is internal medium pressure, external vibration or accidental collision, its bending stress will increase greatly, which can easily lead to fatigue fracture of the level gauge body (such as conduit, panel) or connecting flange. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a segmented liquid level gauge to solve the technical problem of easy fatigue fracture at the main body or connecting flange of the liquid level gauge in the prior art.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: This utility model provides a segmented liquid level gauge, comprising: The bracket has several detachable support components attached to it; The diversion valve body is mounted on the bracket and has a connection end and multiple diversion ends. The connection end is used to connect to the bottom of the container under test and to divert the medium in parallel to the multiple diversion ends. A buffer container, mounted on the support, for connection to the top of the container under test; and The liquid level assembly includes several liquid level cylinder segments, which are connected one-to-one with the support member and connected to the buffer container and the diversion end respectively through pipes, so that the multiple liquid level cylinder segments are arranged alternately from bottom to top, and the end lengths of adjacent liquid level cylinder segments overlap.

[0006] In some embodiments, a plurality of liquid level cylinder segments are arranged in two rows on the support, and the liquid level cylinder segments in the same row are connected in series and communicate with each other through pipes to form two rows of liquid level cylinder groups. The two ends of the liquid level cylinder groups are respectively connected and communicated with the corresponding diversion end and the buffer container.

[0007] In some embodiments, the support includes a mounting base and a support platform. The mounting base is detachably connected to the bracket, and the support platform is fixedly connected to the side of the mounting base away from the bracket. Both ends of the liquid level cylinder section and the pipeline are provided with flanges, and both ends of the support platform are respectively connected to the corresponding flanges by bolts and nuts.

[0008] In some embodiments, the support platform is provided with an expansion joint, which is connected to the flange on the corresponding side by bolts and nuts.

[0009] In some embodiments, the bracket has a plurality of positioning holes arranged in an array for positioning and installing the support member by means of bolts and nuts.

[0010] In some embodiments, the bracket is provided with reinforcing ribs along its length.

[0011] In some embodiments, the buffer container includes a container body, a bend, and a connecting flange. The connecting flange is disposed at the bottom of the container body in a one-to-one correspondence with the liquid level cylinder assembly. The bend is disposed on one side of the container and extends downward.

[0012] In some embodiments, a drain valve is provided on the connection end of the diversion valve body.

[0013] In some embodiments, a valve is provided on the connection end of the flow divider valve body.

[0014] In some embodiments, a ruler plate is also included, which is mounted on the bracket and arranged on both sides of the bracket.

[0015] Compared with the prior art, the segmented level gauge provided by this utility model uses a bracket as the main support part, with multiple segmented level cylinders alternately arranged on the bracket. This enhances the overall support and shortens the effective span of each segment of the level gauge, reducing the probability of bending deformation and breakage of each segment, thus improving safety. Furthermore, the staggered arrangement of the level cylinders can alternately complete the level display at the segment, avoiding the problem of partial display blind spots in the detected level range due to segmented connection, link, or arrangement.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] To address the technical problem that traditional single-section long level gauges are quite heavy, and that their bending stress increases significantly under internal medium pressure, external vibration, or accidental impact, easily leading to fatigue fracture at the level gauge body or connecting flange 33, this invention provides a segmented level gauge. This gauge utilizes a support frame 1 as the main support, with multiple segmented level cylinder segments 41 alternately arranged on the support frame 1. This enhances overall support, shortens the effective span of each segment, reduces the probability of bending deformation and fracture in each segment, and improves safety. Furthermore, the staggered arrangement of the level cylinder segments 41 can intermittently complete the level display at each segment, avoiding blind spots in the detected level range due to segmented connections or arrangements.

[0020] It should be noted that the segmented level gauge described in this utility model is used for, but not limited to, level detection in tanks exceeding three meters but less than nine meters. For ease of explanation, this utility model only uses the application of the segmented level gauge to level detection in tanks exceeding three meters but less than nine meters as an example. The principle of the segmented level gauge applied to other types of equipment is essentially the same as that applied to level detection in tanks exceeding three meters but less than nine meters, and will not be elaborated here.

[0021] Please see Figure 1-6 This utility model provides a segmented level gauge, which includes a support 1, a diversion valve body 2, a buffer container 3, and a level assembly 4. Several support members 5 are detachably connected to the support 1, providing support for each segment of the level cylinder 41, forming a segmented support. The diversion valve body 2 is mounted on the support 1 and has a connecting end 201 and two diversion ends 202. The connecting end 201 connects to the bottom of the container being measured and diverts the medium in parallel to the two diversion ends 202. The buffer container 3 is mounted on the support 1 and connects to the top of the container being measured, connecting each level cylinder 41 to the liquid surface inside the container for pressure balance. Under the connection and communication of the diversion valve body 2... The liquid level assembly 4 is constructed using a communicating vessel structure. Based on the principle of communicating vessels, the liquid level in the measured container and the liquid level cylinder 41 are the same, thus displaying the liquid level height of the measured container. The liquid level assembly 4 includes several liquid level cylinders 41, each connected to a support member 5 in a one-to-one correspondence. These cylinders are also connected to the buffer container 3 and the diversion end 202 via pipes 42, respectively. The multiple liquid level cylinders 41 are arranged alternately from bottom to top, with the end lengths of adjacent liquid level cylinders 41 partially overlapping. These multiple liquid level cylinders 41 cover the entire height range of the measurement height. Furthermore, the partial overlap in length avoids measurement blind spots that may occur with segmentation, achieving uninterrupted liquid level feedback across the entire height range.

[0022] Understandably, the bracket 1 serves as the main support component, with multiple liquid level cylinder segments 41 arranged alternately on the bracket 1 to enhance overall support and shorten the effective span of each segment of the liquid level gauge, thereby reducing the probability of bending deformation and breakage of each liquid level cylinder segment and improving safety.

[0023] It should be noted that there can be multiple diversion ends 202. When there are multiple diversion ends 202, there are correspondingly multiple rows of liquid level cylinder sections 41. This is not a unique limitation, but only a preferred implementation method is provided.

[0024] In one embodiment, please refer to Figure 3 To cover the entire height range of liquid level detection and to streamline the layout space, several liquid level cylinder sections 41 are arranged in two rows on the support 1. The liquid level cylinder sections 41 in the same row are connected in series via pipes 42, forming two rows of liquid level cylinder groups 401. The two ends of each liquid level cylinder group 401 are connected to the corresponding diversion end 202 and the buffer container 3, respectively, thus connecting the two liquid level cylinder groups 41 in parallel with the container being measured, forming a communicating vessel. The liquid level height in both liquid level cylinder sections 41 is flush with the liquid level height in the container being measured. Therefore, in the two liquid level cylinder groups 401, the corresponding liquid level can be observed in one of the liquid level cylinder sections 41.

[0025] In this embodiment, the pipe material of the liquid level cylinder section 41 is required to be semi-transparent or transparent, with a thickness of 2-10mm and a diameter of 5-80mm. The liquid level in the container being measured can be determined by the height of the medium inside the transparent liquid level cylinder section 41, thus achieving the purpose of liquid level visualization.

[0026] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 6 To provide connection support for the pipeline and the liquid level cylinder section 41, the support member 5 includes a mounting base 51 and a support platform 52. The mounting base 51 is detachably connected to the bracket 1 and is bolted to the bracket 1. The support platform 52 is fixedly connected to the side of the mounting base 51 away from the bracket 1. The support platform 52 and the mounting base 51 are integrally formed, and the support platform 51 is flange-shaped. Both ends of the liquid level cylinder section 41 and the pipeline 42 are provided with flanges 43. The two ends of the support platform 52 are respectively connected to the corresponding flanges 43 by bolts and nuts, so that it can be connected to both the pipeline 42 and the liquid level cylinder section 41.

[0027] For further details, please refer to Figure 6In order to compensate for axial thermal expansion, an expansion joint 501 is provided on the support platform 52 based on the original support member 5. The expansion joint 501 is connected to the flange 43 on the corresponding side by bolts and nuts. The other end of the support platform 52 is also connected to the corresponding flange 43 by bolts and nuts.

[0028] Understandably, the support platform 52 provides fixed support for at least one end of the liquid level cylinder section 41, while the expansion joint 501 provides compensation for possible thermal expansion and contraction along the axial direction, thereby improving the safety of the overall structure.

[0029] In one embodiment, please refer to Figure 1 and Figure 3 In order to position and install the support member 5 and to adapt to the increase or decrease of the liquid level cylinder section 41, the bracket 1 is provided with a number of positioning holes 101 in an array for positioning and installing the support member 5 by bolts and nuts. The support member 5 can be installed on the bracket 1 by bolts and nuts according to the required installation position.

[0030] Furthermore, in order to improve the structural stability of the support 1 in the length direction, the support 1 is provided with reinforcing ribs 102 along the length direction to improve the structural strength.

[0031] In one embodiment, please refer to Figure 1 and Figure 2 In order to connect and communicate both liquid level cylinder groups 401 with the buffer container 3, the buffer container 3 includes a container body 31, a bend 32 and a connecting flange 33. The connecting flange 33 is set at the bottom of the container body 31 in a one-to-one correspondence with the liquid level cylinder group 401. The bend 32 is set on one side of the container and extends downward. Through the downward extension of the bend 32, the top liquid level cylinder section 41 is higher than the air pressure communication position of the container being measured.

[0032] It should be noted that the bend 32 is designed to run from the center bisector to the rear of the support 1, requiring a slot to be cut in the top of the support 1. Furthermore, a slotted hole is provided on the support 1, allowing for bolt fastening and adjustment of the height of the buffer container 3. In practical implementation, the bend 32 can also be arranged in a U-shape, bypassing the support 1 from the side to its rear, eliminating the need for a slot in the top center of the support 1. In other words, the bend 32 only needs to extend to the rear of the support 1, adapting to the actual height of the support 1 and structural requirements; no single limitation is imposed here.

[0033] In one embodiment, please refer to Figure 1In order to facilitate maintenance when the liquid level cylinder assembly 401 fails and needs to be replaced or maintained, a drain valve 203 is provided on the connection end 201 of the diversion valve body 2, through which the medium in the liquid level cylinder assembly 401 can be drained.

[0034] Furthermore, a valve 204 is provided on the connection end 201 of the diversion valve body 2, which can cut off the flow of medium from the measured container to the level gauge. When there is still medium in the measured container, the valve 204 needs to be cut off. After opening the drain valve 203 to drain the medium from the level gauge, the corresponding level cylinder section 41 of the level cylinder group 401 can be disassembled for replacement or maintenance.

[0035] In one embodiment, please refer to Figure 5 In order to facilitate observation of the liquid level height when two sets of liquid level cylinder groups 401 are arranged, a scale plate 6 is also included. The scale plate 6 is installed on the bracket 1 and is arranged on both sides of the bracket 1 to display the liquid level height value, so that the liquid level height value can be determined from both sides.

[0036] To better understand this utility model, the following is combined with... Figures 1 to 6 The technical solution of this utility model is described in detail as follows: The bottom of the container being measured is connected to the connecting end 201 of the diversion valve body 2, and the top of the container being measured is connected to the bent pipe 32 of the buffer container 3. Two liquid level cylinder groups 401 are connected in parallel with the container being measured, and both constitute a communicating vessel structure. The two liquid level cylinder groups 401 are arranged alternately from bottom to top and left to right on the support 1, and the lengths of two adjacent liquid level cylinder segments 41 overlap, covering the liquid level detection of the entire height range, and there are no blind spots in the detection display. The liquid level cylinder segments 41 are installed in multiple segments on the support 1. With the connection of the pipe 42 and the support member 5, multi-point support is provided, which enhances the overall support and shortens the effective span of each segment of the liquid level gauge, reducing the probability of bending deformation and breakage of each liquid level cylinder segment, improving safety, and the segmented liquid level cylinder segments 41 are convenient for production, transportation and replacement.

[0037] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
