Description

Technical Field

[0001] This utility model belongs to the field of valve body technology, specifically relating to a repositionable sampling valve. Background Technology

[0002] In fields such as chemical, pharmaceutical, and food processing, which involve fluid production and quality control, sampling valves are key equipment for ensuring fluid quality testing. Their main purpose is to extract representative samples from continuously transported fluid pipelines, and then conduct subsequent testing and analysis on indicators such as fluid composition, purity, and impurity content to ensure that the fluid meets production standards, safety regulations, or process requirements.

[0003] Current sampling valves are mostly single-channel sampling structures, which basically achieve single sample collection by manually controlling the valve opening and closing. The sampling efficiency is low. If multiple sets of parallel samples are needed for comparison and testing, multiple sampling operations need to be repeated, which is time-consuming. In addition, the subsequent dispensing of a large amount of fluid collected at one time also needs to be done separately, which is not convenient. Therefore, a dispensing sampling valve is proposed. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Given the following technical problems in the existing technology: low sampling efficiency, if multiple sets of parallel samples are required for comparative testing, multiple sampling operations need to be repeated, which is time-consuming, and the subsequent dispensing of a large amount of fluid taken at one time also needs to be done separately, which is not convenient.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a resizable sampling valve, comprising a valve body, a connecting pipe installed in the lower middle part of the valve body, a valve installed on the connecting pipe, a branch pipe threaded to the bottom of the connecting pipe, a liquid collecting shell fixedly connected to the bottom of the branch pipe, a plurality of mounting cylinders evenly connected to the bottom of the liquid collecting shell, a sampling bottle installed below the mounting cylinder, a bottle connecting assembly installed in the lower part of the mounting cylinder, and an on / off assembly provided in the upper part of the mounting cylinder.

[0007] By adopting the above technical solution, the valve body is used to connect to the fluid pipeline, and the valve on the connecting pipe controls the flow of liquid to the liquid collection shell. The fluid flows into the branch pipe through the connecting pipe, and then into the liquid collection shell for distribution. The liquid collection shell evenly distributes the fluid to each mounting cylinder. The bottle connecting assembly enables the sampling bottle and the mounting cylinder to be detachably fixed. The on / off assembly controls the flow of fluid in the mounting cylinder, thereby enabling the simultaneous dispensing and sampling of multiple fluids or individual sampling.

[0008] Furthermore, the bottom of the liquid collecting shell is provided with several evenly distributed through openings, and each mounting cylinder is installed in the corresponding mounting opening, with the top of the mounting cylinder flush with the inner bottom wall of the liquid collecting shell.

[0009] By adopting the above technical solution, the uniformly distributed through-holes at the bottom of the liquid collecting shell provide installation conditions for the mounting cylinder. The top of the mounting cylinder is flush with the bottom wall of the liquid collecting shell, avoiding dead corners for fluid residue inside the liquid collecting shell and ensuring that the fluid can flow smoothly into the mounting cylinder.

[0010] Furthermore, the bottle connecting assembly includes a sliding sleeve, which is slidably connected to the inner wall of the mounting cylinder. A support frame is fixedly connected to the inner wall of the sliding sleeve, and a top rod is fixedly connected to the top center of the support frame. A slider is fixedly connected to the wall surface of the sliding sleeve, and a sliding cavity matching the slider is opened in the inner wall of the mounting cylinder.

[0011] By adopting the above technical solution, after the sampling bottle is connected and fixed to the sliding sleeve, the sliding sleeve is pushed to slide along the inner wall of the mounting cylinder, and the slider moves synchronously along the sliding cavity to achieve the guiding and positioning of the sliding sleeve. When the sliding sleeve slides upward, it drives the support frame and the top rod to rise synchronously. The top rod contacts the on / off component and triggers its conduction, allowing the fluid to flow into the sampling bottle. At this time, it can then rotate in the direction of screwing on the sampling bottle and enter the transverse section of the sliding cavity. At this time, the sampling bottle can be automatically collected without pushing it. After sampling is completed, it rotates in the opposite direction, allowing the sampling bottle to rotate in the opposite direction and return to the vertical section of the sliding cavity, resetting and allowing the top rod to disengage from the on / off component, thus closing the on / off component.

[0012] Furthermore, the support frame is cross-shaped, the outer wall of the sliding sleeve slides against the inner wall of the mounting cylinder, and the sliding cavity is divided into a vertical section and a horizontal section, presenting an inverted L-shape.

[0013] By adopting the above technical solution, the "+" shaped support frame ensures the stable installation of the top rod and also ensures that the fluid flows smoothly into the sampling bottle through the sliding sleeve. The outer wall of the sliding sleeve slides in close contact with the inner wall of the mounting cylinder and is sealed to prevent leakage. The vertical section of the inverted L-shaped sliding cavity is used for the slider to move up and down, realizing the triggering and resetting of the on / off component by the top rod. The horizontal section is used for the slider to rotate and position, so that the sliding sleeve is fixed at a specific height, ensuring that the on / off component is continuously conductive.

[0014] Furthermore, the switching component includes a fixing sleeve, which is fixed to the inner wall of the mounting cylinder. Several annularly distributed support bars are fixedly connected to the top side of the fixing sleeve. A connecting bar is fixedly connected to the top of each support bar. The ends of the connecting bars that are close to each other are fixedly connected to the same circular plate. An outer cylinder is fixedly connected to the bottom of the circular plate. A sliding plate is slidably connected in the outer cylinder. An inner rod protruding from the outer cylinder is fixedly connected to the bottom of the sliding plate. A spring is installed between the sliding plate and the circular plate. A blocking platform is fixedly connected to the bottom of the inner rod.

[0015] By adopting the above technical solution, the fixed sleeve provides the installation base for the on / off assembly, and the support bar and connecting bar support the circular plate and the outer cylinder. When there is no external force, the spring is in a naturally extended state, pushing the sliding plate to move downward, which drives the inner rod and the plug to move downward synchronously, so that the plug fits with the fixed sleeve and realizes the closure of the installation cylinder. When the top rod pushes the inner rod upward, the inner rod drives the sliding plate to compress the spring and slide upward, the plug separates from the fixed sleeve, the installation cylinder is open, and the fluid can flow into the sampling bottle through the gap between the fixed sleeve and the plug.

[0016] Furthermore, the cross-section of the blocking platform is an isosceles trapezoid, and the middle of the fixing sleeve is provided with a blocking opening that matches the blocking platform.

[0017] By adopting the above technical solution, the plug and the plug form a conical seal to prevent fluid leakage when closed.

[0018] Furthermore, one end of the spring is connected to the circular plate, the other end of the spring is connected to the sliding plate, the bottom of the inner wall of the sliding sleeve is provided with threads, and the mouth of the sampling bottle is connected to the sliding sleeve through the threads.

[0019] By adopting the above technical solution, the two ends of the spring are fixed to the circular plate and the sliding plate respectively, providing a stable restoring force for the blocking platform and ensuring the sealing reliability of the on / off component when it is closed. The thread at the bottom of the inner wall of the sliding sleeve is engaged with the thread at the mouth of the sampling bottle, realizing the detachable fixed connection between the sampling bottle and the sliding sleeve. The connection is firm and has good sealing performance, avoiding fluid leakage during the sampling process.

[0020] The beneficial effects of this utility model are as follows:

[0021] This invention, through the combined design of a liquid collection shell and multiple mounting cylinders, enables the simultaneous dispensing and sampling of multiple fluid samples, eliminating the need for repeated single-sample sampling operations and significantly reducing sampling time. The bottom penetrations of the liquid collection shell are evenly distributed, and the tops of the mounting cylinders are flush with the inner bottom wall of the liquid collection shell, effectively avoiding fluid residue dead zones and preventing contamination of new samples by previous fluids, thus ensuring sample purity. Simultaneously, the valves on the connecting pipes only need to be opened once to complete the fluid distribution of multiple samples, reducing damage caused by repeated valve opening and closing, extending the equipment's service life. Furthermore, the fluid is evenly distributed to each mounting cylinder through the liquid collection shell, ensuring the consistency of composition and concentration of each sample and improving the accuracy of subsequent test results.

[0034] Reference Figures 1-5 This utility model embodiment proposes a repositionable sampling valve, including a valve body 100. A connecting pipe 200 is installed in the lower middle part of the valve body 100, and a valve is installed on the connecting pipe 200. A branch pipe 300 is threadedly connected to the bottom of the connecting pipe 200, and a liquid collecting shell 400 is fixedly connected to the bottom of the branch pipe 300. A plurality of mounting cylinders 500 are evenly connected to the bottom of the liquid collecting shell 400. A sampling bottle 600 is installed below the mounting cylinder 500. A bottle connecting assembly is installed in the lower part of the mounting cylinder 500, and an on / off assembly is provided in the upper part of the mounting cylinder 500. The valve body 100 is used to connect to a fluid pipe. The valve on the connecting pipe 200 controls the flow of liquid to the liquid collection shell 400. The fluid flows into the branch pipe 300 through the connecting pipe 200, and then into the liquid collection shell 400 for distribution. The liquid collection shell 400 evenly distributes the fluid to each mounting cylinder 500. The bottle connecting assembly enables the detachable fixing of the sampling bottle 600 and the mounting cylinder 500. The on / off assembly controls the flow and closing of the fluid in the mounting cylinder 500, thereby enabling simultaneous sampling of multiple fluid samples or individual sampling. The connection between the valve body 100 and the external pipeline is well known to those skilled in the art and will not be described in detail.

[0035] The bottom of the liquid collecting shell 400 has several evenly distributed through-holes. Each mounting cylinder 500 is installed in the corresponding mounting hole. The top of the mounting cylinder 500 is flush with the inner bottom wall of the liquid collecting shell 400. The evenly distributed through-holes at the bottom of the liquid collecting shell 400 provide installation conditions for the mounting cylinder 500. The flushness between the top of the mounting cylinder 500 and the inner bottom wall of the liquid collecting shell 400 avoids dead corners for fluid residue inside the liquid collecting shell 400 and ensures that the fluid can flow smoothly into the mounting cylinder 500.

[0036] The bottle connecting assembly includes a sliding sleeve 701, which is slidably connected to the inner wall of the mounting cylinder 500. A support frame 702 is fixedly connected to the inner wall of the sliding sleeve 701, and a top rod 703 is fixedly connected to the top center of the support frame 702. A slider 704 is fixedly connected to the wall of the sliding sleeve 701. A sliding cavity 705 matching the slider 704 is formed in the inner wall of the mounting cylinder 500. After the sampling bottle 600 is connected and fixed to the sliding sleeve 701, the sliding sleeve 701 is pushed to slide along the inner wall of the mounting cylinder 500, and the slider 704 moves synchronously along the sliding cavity 705, realizing the guiding of the sliding sleeve 701. When the sliding sleeve 701 slides upward, it drives the support frame 702 and the top rod 703 to rise synchronously. The top rod 703 contacts the on / off assembly and triggers its conduction, allowing the fluid to flow into the sampling bottle 600. At this time, it can then rotate in the direction of screwing on the sampling bottle 600, entering the horizontal section of the sliding cavity 705. At this point, the sampling bottle 600 can be automatically collected without pushing it. After sampling is completed, it rotates in the opposite direction, allowing the sampling bottle 600 to return to the vertical section of the sliding cavity 705, resetting and disengaging the top rod 703 from the on / off assembly, thus closing the on / off assembly.

[0037] The support frame 702 is cross-shaped. The outer wall of the sliding sleeve 701 slides against the inner wall of the mounting cylinder 500. The sliding cavity 705 is divided into a vertical section and a horizontal section, which are inverted L-shaped. The cross-shaped support frame 702 ensures the stable installation of the top rod 703 and also ensures that the fluid flows smoothly through the sliding sleeve 701 into the sampling bottle 600. The outer wall of the sliding sleeve 701 slides against the inner wall of the mounting cylinder 500 and is sealed to prevent leakage. The vertical section of the inverted L-shaped sliding cavity 705 is used for the slider 704 to move up and down, so as to trigger and reset the on / off component of the top rod 703. The horizontal section is used for the slider 704 to rotate and position, so that the sliding sleeve 701 is fixed at a specific height, ensuring that the on / off component is continuously conductive.

[0038] The switching assembly includes a fixed sleeve 801, which is fixed to the inner wall of the mounting cylinder 500. Several annularly distributed support bars 802 are fixedly connected to the top side of the fixed sleeve 801. A connecting bar 803 is fixedly connected to the top of each support bar 802. A circular plate 804 is fixedly connected to the ends of the connecting bars 803 that are close to each other. An outer cylinder 805 is fixedly connected to the bottom of the circular plate 804. A sliding plate 807 is slidably connected within the outer cylinder 805. An inner rod 808 protruding from the outer cylinder 805 is fixedly connected to the bottom of the sliding plate 807. A spring 806 is installed between the sliding plate 807 and the circular plate 804. A blocking platform 809 is fixedly connected to the bottom of the inner rod 808. The fixed sleeve 801 provides an installation base for the on / off assembly. The support bar 802 and the connecting bar 803 support the circular plate 804 and the outer cylinder 805. When no external force is applied, the spring 806 is in a naturally extended state, pushing the sliding plate 807 to move downward, which in turn drives the inner rod 808 and the blocking platform 809 to move downward simultaneously, so that the blocking platform 809 fits with the fixed sleeve 801, thereby closing the installation cylinder 500. When the top rod 703 pushes the inner rod 808 upward, the inner rod 808 drives the sliding plate 807 to compress the spring 806 and slide upward. The blocking platform 809 separates from the fixed sleeve 801, and the installation cylinder 500 becomes open. Fluid can flow into the sampling bottle 600 through the gap between the fixed sleeve 801 and the blocking platform 809.

[0039] The cross-section of the plug 809 is an isosceles trapezoid, and the middle of the fixed sleeve 801 is provided with a plug that matches the plug 809. The plug 809 and the plug form a conical seal to prevent fluid leakage in the closed state.

[0040] One end of the spring 806 is connected to the circular plate 804, and the other end of the spring 806 is connected to the sliding plate 807. The bottom of the inner wall of the sliding sleeve 701 is provided with threads. The mouth of the sampling bottle 600 is connected to the sliding sleeve 701 through threads. The two ends of the spring 806 are fixed to the circular plate 804 and the sliding plate 807 respectively, providing a stable reset force for the blocking platform 809 and ensuring the sealing reliability of the on / off component when it is closed. The threads at the bottom of the inner wall of the sliding sleeve 701 are engaged with the threads at the mouth of the sampling bottle 600, realizing the detachable fixed connection between the sampling bottle 600 and the sliding sleeve 701. The connection is firm and has good sealing performance, avoiding fluid leakage during the sampling process.

[0041] The specific implementation method is as follows: After the valve body 100 is connected to the fluid pipeline, the valve on the connecting pipe 200 controls the flow of fluid. The valve does not need to be opened multiple times. Only once is the fluid passing through the valve body 100 diverted to the liquid collection shell 400, reducing the damage caused by multiple valve openings. The fluid flows into the branch pipe 300 through the connecting pipe 200, and then is introduced into the liquid collection shell 400 for confluence and distribution through the branch pipe 300. The liquid collection shell 400 smoothly distributes the fluid to each mounting cylinder 500 through the evenly distributed through holes at the bottom. The top of the mounting cylinder 500 is flush with the bottom wall of the inner wall of the liquid collection shell 400 to avoid dead corners where fluid remains.

[0042] During sampling, the sampling bottle 600 is fixedly connected to the sliding sleeve 701 inside the mounting cylinder 500 via the bottle neck thread. Pushing the sampling bottle 600 causes the sliding sleeve 701 to slide upward along the inner wall of the mounting cylinder 500. The slider 704 on the wall of the sliding sleeve 701 moves synchronously along the vertical section of the inverted L-shaped sliding cavity 705. At the same time, the push rod 703 moves upward and pushes the blocking platform 809 of the on / off component. The inner rod 808 drives the sliding plate 807 to compress the spring 806 and slide upward. The blocking platform 809 separates from the plug, and the mounting cylinder 500 is opened. The fluid flows into the sampling bottle 600 through the gap between the fixed sleeve 801 and the blocking platform 809. As the sampling bottle 600 is screwed on, the slider 704 enters the horizontal section of the sliding cavity 705 for positioning. The fluid can be automatically collected without continuous pushing.

[0043] After sampling is completed, the sampling bottle 600 is rotated in the reverse direction, the slider 704 returns to the vertical section of the sliding cavity 705, the top rod 703 disengages from the inner rod 808, the spring 806 returns to its natural extension state, pushing the sliding plate 807, the inner rod 808 and the blocking platform 809 to move down, the blocking platform 809 and the plug of the fixed sleeve 801 form a reliable conical surface seal, and the mounting cylinder 500 is closed, thus realizing the synchronous dispensing and sampling of multiple fluids or individual sampling, and the sampling bottle 600 can be easily disassembled for subsequent operations after sampling.

[0044] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
