Description

Technical Field

[0001] The present application relates to the technical field of water meter testing, and more specifically, to a pipeline for testing angle-type industrial water meters, a pipeline system for parallel connection of angle-type and vertical-type industrial water meters, and a method for testing angle-type and vertical-type industrial water meters using the pipeline system. Background Art

[0002] Currently, testing of both vertical and angled industrial water meters uses a single pipeline. This means that after testing a vertical meter, to test an angled meter, the vertical meter must first be removed from the test pipeline and then replaced with the angled meter. Because the inlet and outlet of a vertical meter are aligned or parallel, while the inlet and outlet of an angled meter are typically perpendicular, switching from a vertical meter to an angled meter requires installing a conversion tube before installing the angled meter into the pipeline. This makes both installation and removal of the angled meter extremely inconvenient. Summary of the Invention

[0003] In order to improve the current problem that angle-type industrial water meters and vertical-type industrial water meters share a single test pipeline, and the installation and removal of angle-type industrial water meters are extremely inconvenient, the present application proposes a pipeline for testing angle-type industrial water meters, a pipeline system for angle-type and vertical-type industrial water meters in parallel, and a method for using the pipeline system to test angle-type and vertical-type industrial water meters.

[0004] In a first aspect, the present application proposes an angle-type water meter test pipeline and adopts the following technical solution.

[0005] An angled water meter test pipe includes an inlet pipe and an outlet pipe, the inlet and outlet pipes being arranged perpendicular to each other and capable of aligning with the water inlet and outlet of an angled industrial water meter to be tested, respectively. The angled water meter test pipe also includes a power mechanism capable of translating the outlet pipe toward or away from the outlet.

[0006] By adopting the above technical solution, the angle-type industrial water meter has a separate test pipe, eliminating the need to share a test pipe with a straight-type industrial water meter. This makes both installation and removal of the angle-type industrial water meter more convenient. A power mechanism is provided to drive the outlet pipe toward or away from the outlet, facilitating installation or removal of the angle-type industrial water meter, thereby improving the convenience of meter installation and removal.

[0007] As a preferred form of the angle water meter test pipeline, the water outlet pipe includes a first water outlet pipe section and a second water outlet pipe section that are sealed and interconnected; the power mechanism can push the first water outlet pipe section to translate relative to the second water outlet pipe section, so that the first water outlet pipe section docks with the water outlet, and maintains the sealed connection between the first water outlet pipe section and the second water outlet pipe section during the translation process.

[0008] By adopting the above technical solution, the power mechanism can push the first water outlet pipe section and the angle-type industrial water meter to dock, install or disassemble, and during the docking process, the first water outlet pipe section and the second water outlet pipe section remain connected and sealed, which facilitates installation and disassembly while preventing water leakage.

[0009] As a preferred embodiment of the angle water meter test pipeline, the first water outlet pipe section and the second water outlet pipe section are coaxially connected; the power mechanism includes a cylinder, the cylinder includes a shell and a push rod, the shell is installed on the outer wall of the second water outlet pipe section, and the push rod is parallel to and fixed to the first water outlet pipe section.

[0010] By adopting the above technical solution, the cylinder and the first water outlet pipe section and the second water outlet pipe section are all parallel, and the cylinder can push the first water outlet pipe section to move relative to the second water outlet pipe section. The movement is smooth and efficient, and the structure is simple.

[0011] As a preferred form of the angle water meter test pipeline, the outer wall of the first water outlet pipe section has a first bracket protruding laterally, and the push rod is fixed on the first bracket; the outer wall of the second water outlet pipe section has a second bracket protruding laterally; the shell of the cylinder is hinged to the second bracket.

[0012] By adopting the above technical solution, the push rod and the shell of the cylinder are respectively connected to the first bracket and the second bracket, which can better set the cylinder to be parallel to the first water outlet pipe section and the second water outlet pipe section; and the shell of the cylinder is hinged to the second bracket, which can adapt to the relative angular offset (not on the original axis) of the first water outlet pipe section and the second water outlet pipe section that may occur due to the relative movement of the first water outlet pipe section and the second water outlet pipe section, thereby protecting the cylinder.

[0013] As a further improvement of the angle water meter test pipeline, the power mechanism includes two cylinders, which are symmetrically arranged on both sides of the second water outlet pipe section; the outer wall of the first water outlet pipe section has the first brackets protruding to both sides, and the first brackets are perpendicular to the first water outlet pipe section; the outer wall of the second water outlet pipe section has the second brackets protruding to both sides, and the second brackets are perpendicular to the second water outlet pipe section; the two push rods are respectively fixed to the first brackets on both sides of the first water outlet pipe section; the shell parts of the two cylinders are respectively hinged to the second brackets on both sides of the second water outlet pipe section.

[0014] By adopting this technical solution, two cylinders are symmetrically arranged on either side of the second outlet pipe section, creating a stable structure. The push and pull force lines exerted by the two cylinders on the first outlet pipe section are straighter and more stable than those of a single cylinder. The two cylinders are mounted using first and second brackets that protrude outward from the pipe wall, resulting in a stable overall structure and high adjustment efficiency.

[0015] As an improvement to the angled water meter test pipe, the test pipe further includes a support base and a guide rail. The upper end of the support base is fixed to the first outlet pipe section, and the lower end of the support base is adapted to be mounted on the guide rail. The guide rail is parallel to the first outlet pipe section. The support base can slide along the guide rail when the power mechanism pushes the first outlet pipe section.

[0016] By adopting the above technical solution, the support seat supports the first water outlet pipe section; the support seat is installed on the guide rail, so that the support seat can maintain its supporting role for the first water outlet pipe section during the translation of the first water outlet pipe section. During this process, the first water outlet pipe section only translates and does not move vertically, thereby maintaining a high stability.

[0017] As an improvement to the angle water meter test pipeline, the test pipeline also includes a base, the water inlet pipe is fixed to one end of the base, and the second water outlet pipe section is fixed to the other end of the base; a trough body is provided inside the base; a faucet is installed on the side wall of the water inlet pipe to drain the water in the water inlet pipe, and the faucet faces the trough body; a drain pipe is installed at the bottom of the trough body.

[0018] By adopting the above technical solution, when disassembling the angle-type industrial water meter, the residual water in the pipeline can be discharged into the tank through the faucet, and there is no need to use additional equipment to collect the residual water, which is convenient to use.

[0019] As an improvement to the angle water meter test pipeline, the base and the trough body are both rectangular; the first water outlet pipe section is arranged above the trough body and parallel to the trough body; two support rods and two guide rails are arranged in the trough body; the two support rods are fixed on the trough wall of the trough body in a direction parallel to the width of the trough body but do not contact the bottom of the trough, and the two guide rails are fixed on the two support rods; the two guide rails are located in the same horizontal plane and are parallel to the length direction of the trough body; the support seat is adaptively arranged on the two guide rails.

[0020] By adopting the above technical solution, the first outlet pipe section is positioned above and parallel to the tank, minimizing branching of the test pipeline and keeping its volume small. The guide rail and support base are suspended within the tank, preventing contact with residual water at the bottom while still supporting the first outlet pipe section. This arrangement keeps the test pipeline volume small. These multiple components are integrated into the base, maintaining an orderly and tidy worksite.

[0021] On the second aspect, the present application also proposes a piping system in which an angled water meter test pipe is connected in parallel with a straight meter pipe, and adopts the following technical solution.

[0022] A piping system comprising an angled water meter test line and a straight meter line in parallel, the piping system comprising the angled water meter test line described above, a straight meter line, and a detection line. The straight meter line is used to test straight industrial water meters; the detection line is provided with a flow meter; the angled water meter test line and the straight meter line merge into the detection line; a first on-off valve is installed near the merging point of the angled water meter test line; and a second on-off valve is installed near the merging point of the straight meter line.

[0023] By adopting the above technical solution, the piping system can independently test both angled and straight industrial water meters, while sharing a common test pipeline. This maintains test independence, facilitates disassembly and installation, and improves test pipeline utilization. The placement of a first on-off valve and a second on-off valve near the junction minimizes interference from the non-test branch (the angled water meter test pipeline or the straight meter pipeline) on the test results of the other branch (the straight meter pipeline or the angled water meter test pipeline), ensuring accurate test results. It should be noted that the term "junction" indicates the direction of water flow: water from the angled water meter test pipeline and the straight meter pipeline flows toward the test pipeline. The fact that the angled water meter test pipeline and the straight meter pipeline merge into the test pipeline indicates that the angled water meter test pipeline and the straight meter pipeline are connected in parallel.

[0024] On the third aspect, the present application also proposes a testing method for angular industrial water meters and vertical industrial water meters, and adopts the following technical solution.

[0025] A method for testing an angle-type industrial water meter and a vertical-type industrial water meter is applied to the piping system described above, the method comprising:

[0026] The angle water meter test pipe only tests angle industrial water meters, and the straight meter pipe only tests straight industrial water meters;

[0027] When testing an angle-type industrial water meter, if another angle-type industrial water meter is already installed on the angle-type water meter test pipeline, first remove the bolts connecting the water inlet and water outlet of the other angle-type industrial water meter, start the power mechanism, move the water outlet pipe away from the water outlet, remove the other angle-type industrial water meter, then align the water inlet of the angle-type industrial water meter to be tested with the water inlet pipe, start the power mechanism, move the water outlet pipe against the water outlet of the angle-type industrial water meter to be tested, install the bolts and tighten them, close the second on-off valve, open the first on-off valve, and conduct a water flow test;

[0028] When testing an angle-type industrial water meter, if no angle-type industrial water meter is installed on the angle-type water meter test pipeline, align the water inlet of the angle-type industrial water meter to be tested with the water inlet pipe, start the power mechanism, make the water outlet pipe press against the water outlet of the angle-type industrial water meter to be tested, install and tighten the bolts, close the second on-off valve, open the first on-off valve, and conduct a water flow test;

[0029] When testing a vertical industrial water meter, the vertical industrial water meter to be tested is installed in the vertical meter pipeline, the first switch valve is closed, the second switch valve is opened, and a water flow test is performed.

[0030] By adopting this technical solution, angled and vertical industrial water meters can be tested in two separate branches, making installation and removal of either meter relatively easy. Both branches share a common test pipe, which is equipped with flowmeters and other testing devices, reducing the number of test devices installed and lowering costs. A power mechanism connects the water pipe and water meter, making connection and removal efficient.

[0031] Based on the above description, this application has the following beneficial effects:

[0032] The angled water meter has an independent test line, eliminating the need to share a test line with the straight industrial water meter, making installation and removal of each easier. A pneumatic cylinder or other power mechanism is used to horizontally move the outlet pipe, making it easier to connect and install the angled industrial water meter.

[0033] An angle water meter test pipeline is designed to be connected in parallel with a straight meter pipeline and merge into a pipeline system of a detection pipeline. An angle industrial water meter and a straight industrial water meter are tested in two branches respectively, and it is convenient to dismantle and install any water meter. The two branches share a detection pipeline, and detection devices such as flow meters are installed on the detection pipeline, which reduces the number of detection devices to be installed and reduces costs.

DETAILED DESCRIPTION

[0039] The present application is further described in detail below with reference to the embodiments.

[0040] Please refer to Figure 1 , an angle water meter test pipeline 1, comprising a water inlet pipe 101 and a water outlet pipe 102. The water inlet pipe 101 and the water outlet pipe 102 are arranged perpendicular to each other.

[0041] Please refer to Figure 1 and Figure 2The inlet pipe 101 is used to connect to the water inlet 401 of the angled industrial water meter 4 to be tested, and the outlet pipe 102 is used to connect to the water outlet 402 of the angled industrial water meter 4 to be tested. Optionally, the inlet pipe 101 is arranged vertically, and the outlet pipe 102 is arranged horizontally. It should be noted that the vertical arrangement of the inlet pipe 101 refers to the vertical arrangement of the section near the angled industrial water meter 4, and the horizontal arrangement of the outlet pipe 102 refers to the horizontal arrangement of the section near the angled industrial water meter 4.

[0042] The angle water meter test pipeline 1 further includes a power mechanism capable of translating the water outlet pipe 102 to move the water outlet pipe 102 closer to or away from the water outlet 402 , so as to install or remove the angle industrial water meter 4 .

[0043] In the above test pipeline, the angle industrial water meter 4 has a separate pipeline, which does not need to share a test pipeline with the vertical industrial water meter 201, and the removal and installation of each are relatively convenient. The power mechanism further facilitates the installation and removal of the angle industrial water meter 4.

[0044] Please refer to Figure 1 and Figure 3 , Figure 3 for Figure 1 A partial exploded view of the pipeline. An optional structure of the outlet pipe 102 is that the outlet pipe 102 includes a first outlet pipe section 1021 and a second outlet pipe section 1022 that are sealed and interconnected. For example, the first outlet pipe section 1021 and the second outlet pipe section 1022 are both uniformly cylindrical (in other embodiments, both water pipes can be square, which can also form a sealed connection). The head of the first outlet pipe section 1021 is embedded with a sealing ring 103, which is inserted into the second outlet pipe section 1022. The sealing ring 103 abuts against the inner wall of the second outlet pipe section 1022 to achieve a sealed connection. This design allows the first outlet pipe section 1021 to move relative to the second outlet pipe section 1022 while maintaining a sealed state. Moving the first outlet pipe section 1021 can connect to or move away from the water outlet 402 of the angular industrial water meter 4 to install or remove the angular industrial water meter 4.

[0045] In which, the power mechanism can push the first water outlet pipe section 1021 to translate relative to the second water outlet pipe section 1022, so that the first water outlet pipe section 1021 docks with the water outlet 402, and maintains the sealed connection between the first water outlet pipe section 1021 and the second water outlet pipe section 1022 during the translation process, so that the power mechanism can push the first water outlet pipe section 1021 and the angular industrial water meter 4 to dock, so as to install or dismantle the water meter, and there is no water leakage during the docking process.

[0046] The first water outlet pipe section 1021 and the second water outlet pipe section 1022 can be coaxially connected, that is, at least at the connection point, the first water outlet pipe section 1021 and the second water outlet pipe section 1022 are straight pipes and are on the same straight line. Preferably, the first water outlet pipe section 1021 is a straight pipe as a whole.

[0047] Please refer to Figure 1 In an optional embodiment, the power mechanism includes two cylinders 104, which are symmetrically arranged on both sides of the second water outlet pipe section 1022. Each cylinder 104 includes a shell 1041 and an internal push rod 1042. The shell 1041 is installed on the outer wall of the second water outlet pipe section 1022, preferably installed on the straight pipe section of the second water outlet pipe section 1022 and connected to the first water outlet pipe section 1021. The push rod 1042 is parallel to and fixed to the first water outlet pipe section 1021. Please refer to Figure 3 A preferred method for securing the push rod 1042 parallel to the pipe section is as follows: the outer wall of the first outlet pipe section 1021 has two protruding first brackets 1023, each perpendicular to the first outlet pipe section 1021. The outer wall of the second outlet pipe section 1022 has two protruding second brackets 1024, each perpendicular to the second outlet pipe section 1022. The two push rods 1042 are respectively secured to the first brackets 1023 on either side of the first outlet pipe section 1021. The housings 1041 of the two cylinders 104 are respectively hinged to the second brackets 1024 on either side of the second outlet pipe section 1022.

[0048] The two cylinders 104 are mounted using the first bracket 1023 and the second bracket 1024, which protrude outward from the sides of the pipe wall. This creates a stable overall structure and a straight output force line. Because the housing 1041 of the cylinder 104 is hinged to the second bracket 1024, it can accommodate angular offset (differences in alignment) between the first outlet pipe section 1021 and the second outlet pipe section 1022, which may occur due to movement of the first outlet pipe section 1021 relative to the second outlet pipe section 1022. This synchronizes the angular offset between the cylinders 104 and the second outlet pipe section 1022, thus protecting them.

[0049] Please refer to Figure 1Optionally, the test pipeline also includes a base 105. The water inlet pipe 101 is fixed to one end of the base 105, and the second water outlet pipe section 1022 is fixed to the other end of the base 105. A trough body 1051 is provided in the base 105. A faucet 106 is installed on the side wall of the water inlet pipe 101 to drain the water in the water inlet pipe 101, and the faucet 106 faces the trough body 1051. A drain pipe 107 is installed at the bottom of the trough body 1051, and a valve 108 is installed on the drain pipe 107. When disassembling the angle-type industrial water meter 4, the residual water in the pipeline can be discharged into the trough body 1051 through the faucet 106, and there is no need to use other equipment to collect the residual water, which is convenient to use.

[0050] Alternatively, the base 105 and the tank body 1051 are both rectangular. The base 105 is horizontally arranged, and the first water outlet pipe section 1021 is horizontally arranged above the tank body 1051 and parallel to the tank body 1051, so that the overall structure is neat and orderly.

[0051] Please refer to Figure 1 In a further improved embodiment, the test pipeline further includes a support base 109 and a guide rail 110. The upper end of the support base 109 is a concave arc-shaped plate that fits around and is welded to the lower end of the first outlet pipe section 1021. The lower end of the support base 109 is embedded in the guide rail 110, which is fixedly mounted in the tank body 1051. The guide rails 110 can be installed in the following manner: two support rods 111 and two guide rails 110 are provided in the trough body 1051; the two support rods 111 are fixed to the upper and middle sections of the trough body 1051 in a direction parallel to the width of the trough body 1051, i.e., they do not contact the water at the bottom of the trough; the two guide rails 110 are fixed to the two support rods 111 to form a grid structure; the two guide rails 110 are located in the same horizontal plane and are parallel to the length of the trough body 1051, i.e., parallel to the first water outlet pipe section 1021, to facilitate the translation of the first water outlet pipe section 1021 along the guide rails 110. The support base 109 is adaptively provided on the two guide rails 110.

[0052] Mounting the guide rail 110 and support base 109 in the upper middle portion of the tank 1051 prevents contact with residual water at the bottom of the tank 1051 while still supporting the first outlet pipe section 1021. This arrangement minimizes the volume of the test pipeline. The integration of these components on the base 105 facilitates the overall relocation and installation of the test pipeline.

[0053] Please refer to Figure 4This application also proposes a piping system comprising an angled water meter test pipe 1 connected in parallel with a straight meter pipe 2. The piping system comprises the angled water meter test pipe 1 described above, as well as the straight meter pipe 2 and a detection pipe 3. The straight meter pipe 2 is used to test a straight industrial water meter 201; the detection pipe 3 is provided with an electromagnetic flowmeter 301; the angled water meter test pipe 1 and the straight meter pipe 2 merge at the detection pipe 3; a first on-off valve 112 is installed near the merging position of the angled water meter test pipe 1; and a second on-off valve 202 is installed near the merging position of the straight meter pipe 2.

[0054] The above piping system can independently test both the angled industrial water meter 4 and the straight industrial water meter 201. Both water meters share a common test pipeline 3, maintaining independent testing, facilitating their removal and installation, and improving the utilization of the testing instruments in the test pipeline 3. The first on-off valve 112 and the second on-off valve 202 are positioned near the junction to minimize interference from the non-test branch (angled water meter test pipeline 1 or straight meter pipeline 2) on the test results of the other branch (straight meter pipeline 2 or angled water meter test pipeline 1), ensuring accurate test results. It should be noted that the term "junction" indicates the direction of water flow: water from the angled water meter test pipeline 1 and the straight meter pipeline 2 flows toward the test pipeline 3. The fact that the angled water meter test pipeline 1 and the straight meter pipeline 2 merge into the test pipeline 3 indicates that the angled water meter test pipeline 1 and the straight meter pipeline 2 are connected in parallel.

[0055] Finally, the present application also proposes a test method for the angle-type industrial water meter 4 and the vertical-type industrial water meter 201, which is applied to the piping system described above. The test method includes:

[0056] 1 angle water meter test pipe is used to test angle industrial water meter 4, 2 straight meter test pipes are used to test straight industrial water meter 201;

[0057] When testing the angle-type industrial water meter 4, if another angle-type industrial water meter 4 is already installed on the angle-type water meter test pipeline 1, first remove the bolts connecting the water inlet 401 and the water outlet 402 of the other angle-type industrial water meter 4, start the power mechanism, move the water outlet pipe 102 away from the water outlet 402, remove the other angle-type industrial water meter 4, then align the water inlet 401 of the angle-type industrial water meter 4 to be tested with the water inlet pipe 101, start the power mechanism, move the water outlet pipe 102 against the water outlet 402 of the angle-type industrial water meter 4 to be tested, install the bolts and tighten them, close the second on-off valve 202, open the first on-off valve 112, and conduct a water flow test;

[0058] When testing the angle-type industrial water meter 4, if the angle-type industrial water meter 4 is not installed on the angle-type water meter test pipeline 1, align the water inlet 401 of the angle-type industrial water meter 4 to be tested with the water inlet pipe 101, start the power mechanism, make the water outlet pipe 102 press against the water outlet 402 of the angle-type industrial water meter 4 to be tested, install the bolts and tighten them, close the second on-off valve 202, open the first on-off valve 112, and conduct a water flow test;

[0059] When testing the vertical industrial water meter 201 , the vertical industrial water meter 201 to be tested is installed in the vertical meter pipeline 2 , the first switch valve 112 is closed, and the second switch valve 202 is opened to conduct a water flow test.

[0060] In the above-described testing method, two branches are set up, and the angle-type industrial water meter 4 and the vertical industrial water meter 201 are tested in each branch. Disassembly and assembly of either water meter is relatively convenient. The two branches share a common detection pipe 3, which is equipped with detection devices such as a flow meter. This reduces the number of detection devices installed and reduces costs. The water pipe and water meter are connected by a power mechanism, making connection and disassembly efficient.

[0061] The above are only preferred embodiments of the present application. The scope of protection of the present application is not limited to the above embodiments. All technical solutions based on the concept of the present application are within the scope of protection of the present application. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present application should also be considered within the scope of protection of the present application.
