Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water meter testing, and more particularly to a pipeline structure for testing a straight industrial water meter and a method for installing the straight industrial water meter. BACKGROUND

[0002] When testing a straight industrial water meter, the straight industrial water meter needs to be installed between two pipeline sections. Generally, when multiple water meters need to be tested consecutively, multiple water meters need to be replaced consecutively. Since the straight industrial water meter is large and heavy, it is not easy to fix and align the straight industrial water meter during installation. Currently, the straight industrial water meter is replaced by continuously hanging the straight industrial water meter while adjusting the angle and position and then gradually fastening the straight industrial water meter, which results in low testing efficiency. SUMMARY

[0003] To improve the problem of low efficiency of disassembling and assembling a water meter when testing a straight industrial water meter, the present application provides a pipeline structure for testing a straight industrial water meter and a method for installing the straight industrial water meter, which can improve the efficiency of disassembling and assembling the water meter.

[0004] In a first aspect, the present application provides a pipeline structure for testing a straight industrial water meter, and adopts the following technical solution.

[0005] The pipeline structure for testing a straight industrial water meter includes a water inlet pipe and a water outlet pipe. The straight industrial water meter to be tested has a first flange and a second flange on two sides thereof. The water inlet pipe has a water inlet flange at one end thereof, and the water outlet pipe has a water outlet flange at one end thereof. At least two first support rods are fixed to the periphery of the water inlet flange, and at least two second support rods are fixed to the periphery of the water outlet flange. The two first support rods can support the first flange and make the water inlet flange abut against the first flange. Meanwhile, the two second support rods can support the second flange and make the water outlet flange abut against the second flange.

[0006] By adopting the above technical solution, the flanges on the two sides of the straight industrial water meter to be tested can be placed on the first support rods and the second support rods. The flanges on the two sides of the straight industrial water meter can abut against the water inlet pipe and the water outlet pipe, respectively, so that fastening work can be conveniently performed. The straight industrial water meter does not need to be continuously hung while the angle and position are adjusted and then gradually fastened. Therefore, the efficiency of disassembling and assembling the water meter is improved, and the efficiency of testing the water meter is improved.

[0007] As a preferred mode of the pipeline structure, the diameters of all the first support rods and all the second support rods are the same; each of the first support rods is perpendicular to the water inlet flange and has an equal distance to the center of the water inlet flange; each of the second support rods is perpendicular to the water outlet flange and has an equal distance to the center of the water outlet flange. The pipeline structure further comprises a plurality of groups of shaft sleeves with different outer diameters; each group of the shaft sleeves comprises at least four shaft sleeves with the same outer diameter, and after the shaft sleeves are sleeved on two first support rods and two second support rods and the straight industrial water meter is placed on the shaft sleeves, the first flange is directly connected to the water inlet flange, and the second flange is directly connected to the water outlet flange.

[0008] By adopting the technical scheme, the shaft sleeves matched with the sizes of the flanges at two ends of the straight industrial water meter can be selected, so that the flanges at two ends of the straight industrial water meter are directly connected to the water inlet flange and the water outlet flange, and the installation is more convenient.

[0009] As a further improvement of the preferred mode of the pipeline structure, protruding square limiting blocks are arranged on the first support rods and the second support rods; a sliding groove parallel to the axial direction is formed on one end surface of the shaft sleeve and extends inward along the inner wall of the shaft sleeve, and a limiting groove is formed in the inner section of the sliding groove and extends laterally, so that during the insertion of the shaft sleeve into the first support rod or the second support rod, the sliding groove can accommodate the limiting block until the inner end of the sliding groove abuts against the limiting block, and after the shaft sleeve is rotated in the downward and inward direction, the limiting block can slide into the limiting groove to limit the axial movement.

[0010] By adopting the technical scheme, the limiting block, the sliding groove and the limiting groove matched with the limiting block can limit the axial movement of the shaft sleeve along the first support rod or the second support rod, and prevent the shaft sleeve from being separated from the support rod. It should be noted that the "rotation in the inward direction" means that the two shaft sleeves on the same flange are rotated inwardly towards each other, so that after the straight industrial water meter is pressed on the shaft sleeves, the shaft sleeves will not continue to rotate. If the structure is set to be that the two shaft sleeves are rotated outwardly away from each other, after the straight industrial water meter is pressed on the shaft sleeves, the shaft sleeves may rotate inwardly to the position where the limiting block abuts against the sliding groove, and then the limiting block may move axially out of the first support rod or the second support rod, which brings inconvenience to the installation.

[0011] As a preferred mode of the pipeline structure, the diameters of the water inlet flange and the water outlet flange are equal; the diameters of the first flange and the second flange are equal.

[0012] By adopting the technical scheme, the water inlet flange and the water outlet flange with the same diameter are arranged, the inlet and outlet pipe structures are more symmetrical, and can better match the straight industrial water meters with the same flanges on both sides.

[0013] As a preferred mode of the pipeline structure, the central angle α formed by the two first support rods and the center of the water inlet flange is 85-115°; the central angle β formed by the two second support rods and the center of the water outlet flange is 85-115°.

[0014] By adopting the above technical scheme, the water meter is stable after being placed on the support rods and is not easy to be clamped between the two support rods. When the central angle formed by the two support rods and the center is from 85° to smaller, the stability of the water meter placed on the support rods decreases significantly; when the central angle formed by the two support rods and the center is from 115° to larger, the force of the water meter clamped between the two support rods increases significantly, increasing the difficulty of taking out.

[0015] As a further improvement of the preferred mode of the pipeline structure, the central angle α is equal to the central angle β, and the two first support rods and the two second support rods are all located on the same horizontal plane.

[0016] By adopting the above technical scheme, the structure on both sides of the water meter is more symmetrical, and the water meter is more stable after being placed on the support rods.

[0017] As a preferred mode of the support structure of the pipeline structure, the water inlet flange has two radially protruding ears at the periphery, each first support rod is vertically fixed on one ear; the water outlet flange has two radially protruding ears at the periphery, each second support rod is vertically fixed on one ear.

[0018] By adopting the above technical scheme, the outer diameter of the first support rod and the second support rod has a certain adjustment space, which can be adjusted to match the outer diameter of the flanges on both sides of the water meter, so that it is directly connected with the water inlet flange and the water outlet flange. This ear structure is more material-saving.

[0019] As another preferred mode of the support structure of the pipeline structure, the water inlet flange has an arc-shaped ring protruding radially at the periphery, each first support rod is vertically fixed on the arc-shaped ring; the water outlet flange has an arc-shaped ring protruding radially at the periphery, each second support rod is vertically fixed on the arc-shaped ring.

[0020] By adopting the above technical scheme, this arc-shaped ring structure is more solid and has a long service life.

[0021] As a preferred mode of the pipeline structure, a plurality of strip-shaped holes are provided on the water inlet flange, each strip-shaped hole points to the center of the water inlet flange; a plurality of strip-shaped holes are provided on the water outlet flange, each strip-shaped hole points to the center of the water outlet flange.

[0022] By adopting the technical scheme, each strip-shaped hole points to the center of the water outlet flange, the bolt has a range of optional installation positions, the bolt is suitable for the first flange and the second flange with different diameters in a certain range, and the applicability of the support structure is improved.

[0023] In the second aspect, the application further provides a mounting method of the straight industrial water meter, and adopts the following technical scheme.

[0024] The mounting method of the straight industrial water meter is applied to the pipeline structure for testing the straight industrial water meter, and the mounting method comprises the following steps.

[0025] The water inlet pipe and the water outlet pipe are placed horizontally opposite to each other, so that the water inlet flange and the water outlet flange are in a vertical direction.

[0026] According to the sizes of the first flange and the second flange of the straight industrial water meter to be tested, a matching shaft sleeve is selected, the shaft sleeve is sleeved on the first support rod and the second support rod one by one, and the straight industrial water meter to be tested is placed on the first support rod and the second support rod with the shaft sleeve sleeved thereon, so that the center of the first flange is opposite to the center of the water inlet flange, and the center of the second flange is opposite to the center of the water outlet flange.

[0027] The water inlet pipe or the water outlet pipe is translated, so that the water inlet pipe, the straight industrial water meter and the water outlet pipe are close to each other.

[0028] The circumferential rotation angle of the straight industrial water meter is adjusted, so that a plurality of bolt holes on the first flange are aligned with a plurality of bolt holes on the water inlet flange, and a plurality of bolt holes on the second flange are aligned with a plurality of bolt holes on the water outlet flange.

[0029] The first flange and the water inlet flange are connected by bolts, and the second flange and the water outlet flange are connected by bolts, so as to be in sealed communication, respectively.

[0030] By adopting the technical scheme, the straight industrial water meter can be conveniently, labor-savingly and quickly installed in the pipeline, the water inlet pipe and the water outlet pipe are connected, the difficulty of installing the water meter is reduced, and the efficiency of testing the water meter is improved. Meanwhile, when the water meter is disassembled, the bolts can be disassembled without hoisting the water meter, and then the water meter is moved, which is also labor-saving and convenient.

[0031] The pipeline structure for testing the straight industrial water meter and the mounting method of the application have the following beneficial effects:

[0032] The structure for supporting the water meter is arranged at the ports of the water inlet pipe and the water outlet pipe connected with the industrial water meter, the water meter can be placed on the support structure to install the bolts, and the water meter does not need to be installed by adjusting the angle and position of the water meter while hoisting the industrial water meter, and the scheme of the application significantly improves the work efficiency.

DETAILED DESCRIPTION

[0042] The application will be further described in detail below with reference to the embodiments.

[0043] Please refer to Figure 1 and Figure 2 , a pipeline structure for testing a straight industrial water meter, the straight industrial water meter 1 to be tested has a first flange 101 and a second flange 102 on both sides, respectively, for connecting to the pipelines on both sides. Among them, the first flange 101 of the straight industrial water meter 1 is generally parallel to the second flange 102. The first flange 101 and the second flange 102 are generally coaxial, but can also be decentered, i.e., there can be a certain misalignment. ​​​​​

[0044] The pipeline structure includes an inlet pipe 2 and an outlet pipe 3, both of which can be made of stainless steel. One end of the inlet pipe 2 has an inlet flange 201. One end of the outlet pipe 3 has an outlet flange 301. At least two first support rods 202 are fixed around the periphery of the inlet flange 201, preferably two symmetrically arranged, or three, one at the bottom and the other two symmetrically arranged on both sides.

[0045] like Figure 3 As shown, similarly, at least two second support rods 302 are fixed at the periphery of the outlet flange 301. Two or more first support rods 202 can support the first flange 101 and make the inlet flange 201 connect with the first flange 101. At the same time, two second support rods 302 can support the second flange 102 and make the outlet flange 301 connect with the second flange 102.

[0046] With the above setup, the flanges on both sides of the vertical industrial water meter 1 to be tested can be placed on the first support rod 202 and the second support rod 302. The flanges on both sides of the vertical industrial water meter 1 can be connected to the inlet pipe 2 and the outlet pipe 3 respectively, which can facilitate the tightening operation. It is not necessary to continuously suspend the vertical industrial water meter 1 while adjusting the angle and position and then gradually tightening it, thus improving the efficiency of water meter disassembly and assembly, that is, improving the efficiency of water meter testing.

[0047] In a preferred embodiment, please refer to Figure 4 and Figure 5 , Figure 4 for Figure 1 A frontal view schematic diagram of the inlet pipe end face of the pipeline structure. Figure 5 To be Figure 1 This is a schematic diagram of another embodiment of the pipeline structure with a modified shape at the bottom of the outlet pipe end face. All first support rods 202 and all second support rods 302 have the same diameter. Each first support rod 202 is perpendicular to the inlet flange 201 and is equidistant from the center of the inlet flange 201. Each second support rod 302 is perpendicular to the outlet flange 301 and is equidistant from the center of the outlet flange 301. Based on the fact that the first flanges 101 and second flanges 102 on both sides of a typical vertical industrial water meter 1 are the same size, it is preferable that the diameters of the inlet flange 201 and the outlet flange 301 are also set to be equal to adapt to a typical vertical industrial water meter 1.

[0048] It should be noted that the first flange 101 and the second flange 102 on both sides of the straight industrial water meter 1 are generally circular, at this time, the water inlet flange 201 and the water outlet flange 301 are also correspondingly set to be circular. When the first flange 101 and the second flange 102 are both square, the water inlet flange 201 and the water outlet flange 301 are also correspondingly set to be circular, at this time, the plurality of first supporting rods 202 and the plurality of second supporting rods 302 are arranged on the bottom edges of the water inlet flange 201 and the water outlet flange 301 to support the first flange 101 and the second flange 102.

[0049] It should be noted that since a plurality of straight industrial water meters 1 are to be tested, the plurality of straight industrial water meters 1 can have size differences, that is, the first flange 101 has a plurality of diameters. In order to match the plurality of diameters of the straight industrial water meter 1, on the basis of the above preferred embodiment, the pipe structure further includes a plurality of groups of shaft sleeves 4 with different outer diameters. The shaft sleeve 4 can be made of polytetrafluoroethylene. Each group of shaft sleeves 4 includes at least four shaft sleeves 4 with the same outer diameter, which are sleeved on two first supporting rods 202 and two second supporting rods 302, which are already a combined assembly sufficient to support the straight industrial water meter 1.

[0050] The matching shaft sleeve 4 can be selected according to the size of the flanges at both ends of the straight industrial water meter 1 to be tested. After the straight industrial water meter 1 is placed on the shaft sleeve 4, the first flange 101 is directly connected to the water inlet flange 201, and the second flange 102 is directly connected to the water outlet flange 301. Without hoisting the straight industrial water meter 1, the installation and fastening of the bolts can be completed, and the installation is more convenient.

[0051] As a preferred embodiment, please continue to refer to Figure 4 and Figure 5 In the process of replacing and installing a plurality of straight industrial water meters 1, since the flanges at both ends of the straight industrial water meter 1 have a plurality of sizes, the diameters of the circular holes surrounded by the plurality of bolt holes 1010 on the water meter flange are different, and therefore a plurality of (such as eight) strip-shaped holes 2010 are uniformly arranged on the water inlet flange 201, each strip-shaped hole 2010 (which can be waist-shaped) points to the center of the water inlet flange 201; a plurality of (such as eight) strip-shaped holes 2010 are uniformly arranged on the water outlet flange 301, each strip-shaped hole 2010 (which can be waist-shaped) points to the center of the water outlet flange 301. The bolt holes 1010 on the water meter flange are generally circular, and the width of the strip-shaped hole 2010 arranged on the water inlet flange 201 and the water outlet flange 301 is equal to the diameter of the bolt hole 1010 on the water meter flange. By using the above technical solution, the strip-shaped hole 2010 allows the bolt to have a certain range of optional installation positions, and the bolt is adapted to the first flange 101 and the second flange 102 with different diameters within a certain range, thereby improving the applicability of the support structure.

[0052] Further preferably, as shown in FIG. 1, the first support rod 202 and the second support rod 302 are provided with protruding square limiting blocks 2020 during the adjustment process after the straight industrial water meter 1 is placed on the shaft sleeve 4, in order to prevent the shaft sleeve 4 from being detached from the support rod. Accordingly, a sliding groove 401 parallel to the axial direction is formed on one end surface of the shaft sleeve 4 along the inner wall of the shaft sleeve 4, and a limiting groove 402 is formed on the inner segment of the sliding groove 401 in the lateral direction, so that the sliding groove 401 can accommodate the limiting block 2020 until the limiting block 2020 is stopped by the inner end of the sliding groove 401 during the insertion of the shaft sleeve 4 into the first support rod 202 or the second support rod 302, and the limiting block 2020 can be slid into the limiting groove 402 to limit the axial movement after the shaft sleeve 4 is rotated in the downward and inward direction. Figure 6 Figure 7

[0053] By providing the limiting block 2020 and the sliding groove 401 and the limiting groove 402 cooperating with the limiting block 2020, the axial movement of the shaft sleeve 4 along the first support rod 202 or the second support rod 302 can be limited, and the shaft sleeve 4 can be prevented from being detached from the support rod. It should be noted that the "rotation in the inward direction" refers to the rotation of the two shaft sleeves 4 in the same flange in the opposite and inward direction, so that the shaft sleeve 4 will not continue to rotate after the straight industrial water meter 1 is pressed on the shaft sleeve 4. If the structure is designed such that the two shaft sleeves 4 are rotated in the opposite and outward direction, the shaft sleeve 4 may be rotated inwardly to the position where the limiting block 2020 is stopped by the sliding groove 401 after the straight industrial water meter 1 is pressed on the shaft sleeve 4, and then the limiting block 2020 may be axially detached from the first support rod 202 or the second support rod 302, which brings inconvenience to the installation.

[0054] As preferred, as shown in FIG. 1, the central angle α between the two first support rods 202 and the center of the water inlet flange 201 is 85-115°, and the central angle β between the two second support rods 302 and the center of the water outlet flange 301 is 85-115°. Figure 4 Figure 5 It is found through experiments that, by using the above-mentioned angle, the water meter is more stable after being placed on the support rod and is not easily clamped between the two support rods. If the central angle between the two support rods and the center is set to be smaller than 85°, the stability of the water meter placed on the support rod decreases significantly, and if the central angle between the two support rods and the center is set to be larger than 115°, the force with which the water meter is clamped between the two support rods increases significantly, which increases the difficulty of taking out the water meter.

[0055] ​​​As a further preferred, the circle center angle α = the circle center angle β, and both the two first support rods 202 and the two second support rods 302 are located on the same horizontal plane, so that the structure supporting the water meter on both sides is more symmetrical, and the water meter is more stable after being placed on the support rods.

[0056] The above-mentioned water inlet flange 201 is fixed with at least two first support rods 202 at the periphery, and the water outlet flange 301 is fixed with at least two second support rods 302 at the periphery, preferably two first support rods 202 are fixed at the periphery of the water inlet flange 201, and two second support rods 302 are fixed at the periphery of the water outlet flange 301, so that the structure is simple and stable.

[0057] A. Please refer to Figure 4 , the water inlet flange 201 has two radially protruding ears 203 at the periphery, which can be square, can be welded at the periphery of the water inlet flange 201, or can be integrally formed with the water inlet flange 201. Each first support rod 202 is fixed vertically on one ear 203, which can be integrally formed with the first support rod 202 and the ear 203, or the ear 203 can be provided with one or more threaded holes 2030, and the threaded holes 2030 of the two ears 203 are symmetrically arranged one by one. One end of the first support rod 202 is provided with external threads, the first support rod 202 is screwed into one of the threaded holes 2030 of the ear 203, and is locked with a nut 204 on the back, and the two first support rods 202 are symmetrically installed. Similarly, the periphery of the water outlet flange 301 can be provided with two radially protruding ears 203, each second support rod 302 is fixed vertically on one ear 203, and the optional way is the same as the fixing way of the first support rod 202. This ear 203 structure is more material-saving. A plurality of symmetrically arranged threaded holes 2030 are provided on the two ears 203, and a group of symmetrically arranged threaded holes 2030 can be selected to install the support rods to obtain a support rod-circle center-support rod structure with different circle center angles, so as to load different sizes of straight industrial water meters 1.

[0058] B. Please refer to Figure 5The periphery of the water inlet flange 201 is provided with a radially protruding arc-shaped ring 205, and each first supporting rod 202 is vertically fixed on the arc-shaped ring 205. The arc-shaped ring 205 can be welded on the lower periphery of the water inlet flange 201 or can be integrally formed with the water inlet flange 201. The first supporting rod 202 can be integrally formed with the arc-shaped ring 205, or the arc-shaped ring 205 is provided with one pair or two pairs or more than two pairs of threaded holes 2030, and one end of the first supporting rod 202 is provided with external threads, and two first supporting rods 202 are screwed into two symmetrical threaded holes 2030 on the arc-shaped ring 205 and locked by nuts 204 from the back. Similarly, the periphery of the water outlet flange 301 is provided with a radially protruding arc-shaped ring 205, and the arc-shaped ring 205 can be welded on the lower periphery of the water outlet flange 301 or can be integrally formed with the water outlet flange 301. Each second supporting rod 302 is vertically fixed on the arc-shaped ring 205. The second supporting rod 302 can be integrally formed with the arc-shaped ring 205, or the arc-shaped ring 205 is provided with one pair or two pairs or more than two pairs of threaded holes 2030, and one end of the second supporting rod 302 is provided with external threads, and two second supporting rods 302 are screwed into one pair of symmetrical threaded holes 2030 on the arc-shaped ring 205 and locked by nuts 204 from the back. The arc-shaped ring 205 structure is relatively firm and has a long service life.

[0060] In the case that the straight industrial water meter 1 is not installed between the water inlet pipe 2 and the water outlet pipe 3, the water inlet pipe 2 and the water outlet pipe 3 are placed horizontally opposite to each other, so that the water inlet flange 201 and the water outlet flange 301 are in the vertical direction;

[0061] According to the size of the first flange 101 and the second flange 102 of the straight industrial water meter 1 to be tested, a matching shaft sleeve 4 is selected, the shaft sleeve 4 is sleeved on the first supporting rod 202 and the second supporting rod 302, and the straight industrial water meter 1 to be tested is placed on the first supporting rod 202 and the second supporting rod 302 with the shaft sleeve 4, so that the center of the first flange 101 is opposite to the center of the water inlet flange 201, and the center of the second flange 102 is opposite to the center of the water outlet flange 301;

[0062] The water inlet pipe 2 or the water outlet pipe 3 is translated so that the water inlet pipe 2, the straight industrial water meter 1 and the water outlet pipe 3 are close to each other. Here, the translation can be the movement of the water inlet pipe 2 or the water outlet pipe 3 pushed by the pre-installed electric push rod, or can be pushed by hand.

[0063] The circumferential rotation angle of the straight industrial water meter 1 is adjusted, so that the plurality of bolt holes 1010 on the first flange 101 are aligned with the plurality of bolt holes 1010 on the water inlet flange 201, and the plurality of bolt holes 1010 on the second flange 102 are aligned with the plurality of bolt holes 1010 on the water outlet flange 301.

[0064] The first flange 101 and the water inlet flange 201 are connected by bolts, and the second flange 102 and the water outlet flange 301 are connected by bolts, so as to be in airtight communication, respectively.
