Description

Technical Field

[0001] The utility model relates to the technical field of flow calibration columns, in particular to a leak-proof flow calibration column with sufficient protection. Background Technique

[0002] A flow calibration column is a pipeline component used to calibrate the flow rate of a pump, and is widely used in metering pumps and other pump systems to accurately calibrate the flow rate output by the metering pump.

[0003] However, the overall structure of the existing flow calibration column is relatively simple, mostly using an integrated structure. The container material mostly uses plexiglass, and no corresponding protective structure is provided outside, making it easy to be damaged during normal use, increasing the working cost. Moreover, the assembly structure of the existing flow calibration column mostly uses a single thread or flange assembly, and the overall assembly tightness is relatively general, and it is easy to leak due to wear during long-term use, which greatly affects the overall use effect. At the same time, the installation between the existing flow calibration column and the equipment requires determining the installation direction, which has a certain impact on the convenience of overall assembly and use, resulting in a relatively narrow scope of application.

[0004] Based on this, the utility model proposes a leak-proof flow calibration column with sufficient protection to solve the above problems. Summary of the Utility Model

[0005] The purpose of this part is to outline some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this part, as well as in the abstract and the name of the utility model of the specification, to avoid obscuring the purpose of this part, the abstract of the specification, and the name of the utility model. However, such simplifications or omissions shall not be used to limit the scope of the utility model.

[0006] In view of the above and / or existing problems in the design of flow calibration columns, the present utility model is proposed.

[0007] Therefore, one of the purposes of the present utility model is to provide a leak-proof flow calibration column with sufficient protection, which greatly optimizes and improves the container structure of the traditional flow calibration column, slews a metal shell outside to provide external protection for the internal container, and uses a grooving structure to enable the observation of the flow scale of the internal container without affecting the basic protection effect, enriching the overall use functionality.

[0008] To achieve the above effects, the present utility model provides the following technical solutions: A fully protected anti-leakage flow calibration column, including a protective housing, inside which a liquid accumulation container is fixedly installed. A scale viewing window groove is penetrated and opened on the outside of the protective housing. On both sides of the outside of the liquid accumulation container, flow scales are preset in a reverse symmetrical manner. The preset positions of the flow scales on the outside of the liquid accumulation container correspond and match with the penetrated opening positions of the scale viewing window groove on the outside of the protective housing. At the upper end position of the outside of the protective housing, a first-stage double sleeve flange is movably installed, and at the lower end position of the outside of the protective housing, a second-stage double sleeve flange is movably installed.

[0009] As a preferred scheme of the fully protected anti-leakage flow calibration column of the present utility model, wherein: The overall protective housing is a hollow sleeve structure made of metal stainless steel, and the inner diameter size of the protective housing corresponds and matches with the outer diameter size of the liquid accumulation container. The overall liquid accumulation container is a hollow cylindrical sleeve structure made of tempered glass;

[0010] Through the structural and material characteristics of the adopted protective housing, it is possible to improve the external protection use effect of itself, reduce the damage risk, and improve the use strength without affecting the basic use performance of the flow calibration column.

[0011] As a preferred scheme of the fully protected anti-leakage flow calibration column of the present utility model, wherein: At the middle positions of the upper end and the bottom of the protective housing, docking mounting sleeves are symmetrically and fixedly installed. The inside of the docking mounting sleeves penetrates through the protective housing and is interconnected with the inside of the liquid accumulation container. Sealing gaskets are symmetrically and fixedly installed on the outer ring positions at the joints of the docking mounting sleeves at the upper end and the bottom of the protective housing;

[0012] By adding the sealing gaskets, it is possible to further improve the use sealing performance after the assembly of the flow calibration column.

[0013] As a preferred scheme of the fully protected anti-leakage flow calibration column of the present utility model, wherein: On the outside of the first-stage double sleeve flange and the second-stage double sleeve flange, docking flange holes are symmetrically opened at equal intervals in a ring shape. At the middle position of the bottom of the first-stage double sleeve flange and the middle position of the upper end of the second-stage double sleeve flange, internal thread docking sleeves are fixedly installed;

[0014] By adopting a flange connection structure with double-end tight assembly and combining the two-way setting of the flow scales, when the flow calibration column is assembled and docked with the equipment, there is no need to deliberately determine the assembly direction, and it can be used normally with double-end alignment installation, effectively enriching the overall use functionality.

[0015] As a preferred solution of the fully protected anti-leakage flow calibration column of the utility model, wherein: the inner wall of the docking assembly sleeve is preset with an internal thread groove, and the outer wall of the docking assembly sleeve is preset with an external thread groove, and the internal thread groove and the external thread groove are thread grooves in the same direction;

[0016] Through the double thread structure design of the internal and external thread grooves corresponding to the inside and outside of the docking assembly sleeve, the flow calibration column can be stably double-threadedly docked with the external first-level double-set flange and the second-level double-set flange, and then the alignment assembly operation with the external designated equipment can be carried out, thereby effectively improving the overall structural stability.

[0017] As a preferred solution of the fully protected anti-leakage flow calibration column described in the utility model, wherein: an externally threaded docking sleeve is fixedly installed in the middle position inside the internally threaded docking sleeve, the internal thread of the internally threaded docking sleeve and the external thread of the externally threaded docking sleeve are both unidirectional threads, the inner diameter size of the internally threaded docking sleeve is mutually adapted to the outer diameter size of the docking assembly sleeve, and the outer diameter size of the externally threaded docking sleeve is mutually corresponding to the inner diameter size of the docking assembly sleeve, the internal thread specification of the internally threaded docking sleeve is mutually corresponding to the external thread groove specification on the outside of the docking assembly sleeve, and the external thread specification of the externally threaded docking sleeve is mutually adapted to the specification of the external thread groove opened inside the docking assembly sleeve;

[0018] By adopting a double-thread assembly structure, the overall assembly convenience is improved while the overall assembly stability is correspondingly enhanced. The double-thread structure can be used to minimize the occurrence of liquid leakage during the use of the flow calibration column, and the overall use effect is optimized and improved.

[0019] The beneficial effects of the utility model: the utility model optimizes and improves the container structure of the traditional flow calibration column to a great extent, sets a metal shell on the outside to provide external protection for the internal container, and utilizes a slotted structure to achieve basic protection effects without affecting the flow scale observation of the internal container, thereby enriching the overall functionality of use and correspondingly improving the overall structural strength and comprehensive performance. The traditional flange docking structure is structurally optimized and a double-threaded docking structure is adopted. While ensuring that the overall fluidity is not affected, the anti-leakage effect of the flow calibration column in normal use is effectively enhanced, thereby effectively improving the overall assembly and use sealing. At the same time, the design of the double-threaded assembly structure also effectively improves the assembly speed of the flange on the outside of the flow calibration column, which helps to improve the overall convenience of assembly and use, greatly improves the overall comprehensive performance, expands the scope of application to a certain extent, and has a relatively broad application prospect.

[0030] Please refer to Figures 1 - 5, the present utility model provides a technical solution: a fully protected leak-proof flow calibration column, comprising a protective housing 1, a liquid accumulation container 2, a scale viewing window groove 3, a docking fitting sleeve 4, a first-stage double sleeve flange 5, a second-stage double sleeve flange 6, a flow scale 7, a sealing gasket 8, an internal thread groove 9, an external thread groove 10, a docking flange hole 11, an internal thread docking sleeve 12 and an external thread docking sleeve 13. A liquid accumulation container 2 is fixedly installed inside the protective housing 1. A scale viewing window groove 3 is penetratingly opened on the outside of the protective housing 1. Flow scales 7 are symmetrically preset on both sides of the outside of the liquid accumulation container 2 in opposite directions. The preset position of the flow scales 7 on the outside of the liquid accumulation container 2 corresponds and coincides with the penetrating opening position of the scale viewing window groove 3 on the outside of the protective housing 1. A first-stage double sleeve flange 5 is movably installed at the upper end position of the outside of the protective housing 1. A second-stage double sleeve flange 6 is movably installed at the lower end position of the outside of the protective housing 1. The protective housing 1 is an overall hollow sleeve structure made of metal stainless steel, and the inner diameter dimension of the protective housing 1 corresponds and matches the outer diameter dimension of the liquid accumulation container 2. The liquid accumulation container 2 is an overall hollow cylindrical sleeve structure made of tempered glass. Docking fitting sleeves 4 are symmetrically and fixedly installed at the middle positions of the upper end and the bottom of the protective housing 1. The inside of the docking fitting sleeves 4 passes through the protective housing 1 and is interconnected with the inside of the liquid accumulation container 2. Sealing gaskets 8 are symmetrically and fixedly installed on the outer ring positions of the connections between the docking fitting sleeves 4 at the upper end and the bottom of the protective housing 1. Docking flange holes 11 are symmetrically opened at equal intervals in a ring shape on the outside of both the first-stage double sleeve flange 5 and the second-stage double sleeve flange 6. Internal thread docking sleeves 12 are fixedly installed at the middle positions of the bottom of the first-stage double sleeve flange 5 and the upper end of the second-stage double sleeve flange 6. An internal thread groove 9 is preset on the inner wall of the docking fitting sleeve 4, and an external thread groove 10 is preset on the outer wall of the docking fitting sleeve 4. The internal thread groove 9 and the external thread groove 10 are the same-direction thread grooves. An external thread docking sleeve 13 is fixedly installed at the middle position inside the internal thread docking sleeve 12. The internal thread of the internal thread docking sleeve 12 and the external thread of the external thread docking sleeve 13 are the same-direction threads. The inner diameter dimension of the internal thread docking sleeve 12 corresponds and matches the outer diameter dimension of the docking fitting sleeve 4, and the outer diameter dimension of the external thread docking sleeve 13 corresponds and matches the inner diameter dimension of the docking fitting sleeve 4. The internal thread specification of the internal thread docking sleeve 12 corresponds and matches the external thread groove 10 specification on the outside of the docking fitting sleeve 4. The external thread specification of the external thread docking sleeve 13 corresponds and matches the external thread groove 10 specification opened inside the docking fitting sleeve 4;

[0031] Through the structural and material characteristics of the adopted protective housing 1, it is possible to improve the external protection effect of itself, reduce the damage risk, and enhance the service strength without affecting the basic performance of the flow calibration column. By adding a sealing gasket 8, the sealing performance after assembly of the flow calibration column can be further improved. By adopting a flange connection structure with double-end tight assembly and combining the bidirectional setting of the flow scale 7, when the flow calibration column is assembled and docked with the equipment, there is no need to deliberately determine the assembly direction, and it can work normally with double-end alignment installation. The overall service functionality is effectively enriched. Through the double-thread structure design of the inner thread groove 9 and the outer thread groove 10 correspondingly opened inside and outside the docking sleeve 4, after the flow calibration column is stably double-threaded docked with the external primary double flange 5 and the secondary double flange 6, the alignment assembly operation with the external specified equipment is carried out, thus effectively improving the overall structural stability. By adopting the double-thread assembly structure, on the basis of improving the overall assembly convenience, the overall assembly stability is correspondingly enhanced, and the double-thread structure can be used to minimize the liquid leakage during the use of the flow calibration column. The overall use effect is optimized and improved.

[0032] Working principle:

[0033] During normal use, the flow calibration column should first complete its own alignment and assembly. The first-stage double flange 5 and the second-stage double flange 6 are respectively and stably double-threadedly docked and assembled with the docking sleeves 4 at the upper end and the bottom of the outer part of the protective housing 1 through the internal-thread docking sleeve 12. By using the alignment and adaptation structure between the internal thread of the internal-thread docking sleeve 12 and the external thread groove 10 on the outside of the docking sleeve 4, and the alignment and adaptation structure between the external thread of the external-thread docking sleeve 13 and the internal thread groove 9 on the inner wall of the docking sleeve 4, combined with the same-direction thread structure of the internal thread groove 9 and the external thread groove 10, the first-stage double flange 5 and the second-stage double flange 6 can be tightly threadedly connected at both ends of the outside of the protective housing 1, effectively ensuring the internal sealing of the liquid accumulation container 2 after the first-stage double flange 5 and the second-stage double flange 6 are assembled with the protective housing 1. And the sealing gasket 8 can seal the connection between the first-stage double flange 5 and the second-stage double flange 6 and the outside of the protective housing 1, further preventing leakage during the use of the flow calibration column. On the basis of achieving the use effect of quick assembly, the use sealing performance of itself is guaranteed to the greatest extent. Then, through the alignment and assembly between the first-stage double flange 5 and the second-stage double flange 6 and the corresponding equipment, the installation operation of the flow calibration column on the designated equipment is realized and it can be used normally. The hollow structure of the scale window groove 3 helps the flow calibration column to more quickly observe the internal flow of the liquid accumulation container 2 during use. The two-way preset structure of the flow scale 7 on the outside of the liquid accumulation container 2 enables the flow calibration column to not need to deliberately determine the installation direction during installation, improving the overall installation convenience and correspondingly improving the overall use effect, and reducing the occurrence of leakage during use.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
