[0038] Embodiment 1

[0039] Figure 1 This is the structural schematic diagram of the disassembly and assembly tooling for this application; as Figure 1 shown, the disassembly and assembly tooling includes: a mounting pressure plate;

[0040] The joint flange 20 includes a flange plate 200 and a flange pipe; the flange plate 200 and the flange pipe 210 are integrally connected;

[0041] The mounting pressure plate includes a first cross plate 100 and a second cross plate 110 arranged in parallel; a first space is formed between the first cross plate 100 and the second cross plate 110 for mounting the flange plate 200 of the joint flange 20, and the second cross plate 110 supports the flange plate 200; the first cross plate 100 is provided with a first opening 101 to embed the flange pipe 210 of the joint flange 20; the joint flange 20 is detachably connected to the mounting pressure plate through a first fixing member;

[0042] The joint flange 20 is used for threaded connection with the threaded valve 30.

[0043] In practical applications, after the joint flange and the threaded valve of the water supply equipment are connected, a firm connection and sealing between pipeline systems, control of medium flow, and stability and safety of the system can be achieved; it is of great significance for ensuring the normal operation of the water supply equipment and the safe and stable operation of the water supply system. The disassembly and assembly tooling in this example is used for the installation of the joint flange 20 and the threaded valve 30; the joint flange 20 is composed of a flange plate 200 and a flange pipe 210 that are integrally connected. The disassembly and assembly tooling includes an installation pressing plate; the installation pressing plate includes a first cross plate 100 and a second cross plate 110, the first cross plate 100 and the second cross plate 110 are arranged in parallel, and a first space is formed between the first cross plate 100 and the second cross plate 110; the first space is used for installing the flange plate 200 of the joint flange 20, and the second cross plate 110 supports the flange plate 200. A first opening 101 is formed in the first cross plate 100, and the flange pipe 210 part of the joint flange 20 is embedded into the first opening 101; after the joint flange 20 is installed on the installation pressing plate, a first fixing member is used for fixing to stably fix the joint flange 20 on the installation pressing plate; then the fixed joint flange 20 is connected to the threaded valve 30. Before the threaded valve 30 is connected to the joint flange 20, the threaded valve 30 is placed to align the threads with the joint flange 20 and is tightened by rotating it to the right. Exemplarily, when the threaded valve 30 and the joint flange 20 are connected, an appropriate amount of sealing material, such as Teflon tape or sealant, is applied to the threaded interface of the threaded valve 30; to enhance the sealing performance of the connection and prevent medium leakage. Align the threaded interface of the threaded valve 30 with the threaded hole of the joint flange 20 and slowly rotate the threaded valve 30 to gradually screw it into the threaded hole of the flange; during the rotation process, it is necessary to ensure that the threaded interface of the threaded valve 30 is closely fitted with the threaded hole of the joint flange 20 to avoid skewing or jamming. When the threaded valve 30 is completely screwed into the threaded hole of the joint flange 20, tools such as a wrench are used to tighten the threaded valve 30; attention should be paid to applying appropriate force during tightening, ensuring both the firmness of the connection and avoiding over-tightening that may cause thread damage or sealant failure. The threaded connection has the advantages of simple structure, convenient installation, good sealing performance, etc., and is widely used in fields such as water supply equipment. In this example, the installation pressing plate is used to stably fix the joint flange, ensuring the reliability of the connection between the joint flange and the threaded valve and improving the installation efficiency.

[0044] Specifically, when fixing the joint flange 20 on the installation pressing plate, it is necessary to pass the fixing member through the installation pressing plate; correspondingly, as an example, the first cross plate 100 is also provided with a first through hole 102; the second cross plate 110 is provided with a second through hole 111; the first through hole 102 corresponds to the first bolt hole on the flange plate 200 and the second through hole 111, and the first fixing member sequentially passes through the first through hole 102, the first bolt hole on the flange plate, and the second through hole 111 to fix the joint flange 20 to the installation pressing plate.

[0045] In this example, a first through hole 102 is provided on the first horizontal plate 100 of the mounting pressing plate; at the same time, a second through hole 111 is provided on the second horizontal plate 110 supporting the flange 200; the first through hole 102 corresponds to the second through hole 111. The first fixing member needs to sequentially pass through the first through hole 102, the first bolt hole on the flange 200, and the second through hole 111 to fixedly install the joint flange 20 on the mounting pressing plate. In this example, by providing through holes on the first horizontal plate and the second horizontal plate and making the through holes correspond to each other, the first fixing member passes through the through holes and the bolt holes on the flange of the joint flange, and the joint flange is fixed to the mounting pressing plate, improving the stability of the joint flange and further enhancing the subsequent installation efficiency of the joint flange and the threaded valve.

[0046] Specifically, through holes need to be provided at appropriate positions; the number of the first through holes 102 is multiple, and the multiple first through holes 102 are symmetrically distributed with the first opening 101 as the center.

[0047] In this example, the number of the first through holes 102 is multiple, and the number of the first through holes 102 is not limited in this example. The multiple first through holes 102 are symmetrically distributed with the first opening 101 as the center. Correspondingly, the number of the corresponding second through holes 111 is also multiple. In this example, multiple first through holes are provided on the first horizontal plate, and the first through holes are arranged in a symmetric distribution form with the first opening as the center; the joint flange can be fixed at the central position of the mounting pressing plate, improving the stability of the fixation of the joint flange, thereby enhancing the accuracy of the connection between the joint flange and the threaded valve and improving the installation efficiency.

[0048] Specifically, in order to install the joint flanges 20 of different sizes and the corresponding threaded valves 30 of different sizes, as an example, the first horizontal plate 100 is provided with multiple groups of through holes, and each group includes multiple first through holes 102; the distances from the first through holes 102 in the same group to the center of the first opening 101 are the same, and the distances from the first through holes 102 in different groups to the center of the first opening 101 are different; the multiple groups of through holes are respectively used to adapt to and install the joint flanges 20 of different sizes.

[0049] In this example, multiple sets of first through holes 102 are provided on the first horizontal plate 100, and the number of first through holes 102 in each set is multiple. The number of first through holes 102 in each set is not limited in this example. The central distance of the first through holes 102 within the same group with respect to the center of the first opening 101 is equal, which can enable the joint flange 20 to be installed at the central position of the mounting pressing plate and enable the joint flange 20 to be stably installed on the mounting pressing plate. The central distances of the first through holes 102 in different groups from the center of the first opening 101 are different. Multiple sets of first through holes 102 with different central distances from the center of the first opening 101 can achieve the installation of joint flanges 20 of different sizes; correspondingly, the joint flanges 20 of different sizes correspond to the threaded valves 30 of corresponding sizes, so the installation of joint flanges 20 and threaded valves 30 of multiple sizes can be achieved. It should be noted that when multiple sets of first through holes are provided, multiple sets of second through holes 111 are also correspondingly provided, that is, multiple sets of second through holes 111 are also provided, and the number of second through holes 111 in each set is multiple, and the number is not limited. In this example, by providing multiple sets of first through holes, the installation of joint flanges and threaded valves of different sizes can be achieved, improving the installation efficiency and applicability.

[0050] Specifically, in order to achieve the stability of the installation of the joint flange 20, the mounting pressing plate needs to be stably fixed on the workbench. The mounting pressing plate further includes a connecting plate 130 and a third horizontal plate 120; the connecting plate 130 is vertically connected to the second horizontal plate 110 and the third horizontal plate 120; the third horizontal plate 120 is provided with a third through hole 121 to fix the mounting pressing plate to the workbench through the third through hole 121 using screws.

[0051] Exemplarily, the mounting pressing plate further includes a connecting plate 130 and a third horizontal plate 120; the connecting plate 130 is perpendicular to the second horizontal plate 110 and the third horizontal plate 120 and connects the second horizontal plate 110 and the third horizontal plate 120. The number of connecting plates 130 can be multiple, and the number of connecting plates 130 is not limited in this example. The third horizontal plate 120 is provided with a third through hole 121, and screws are passed through the third through hole 121 to fix the entire mounting pressing plate to the workbench. It should be noted that the number of third through holes 121 can be multiple, and the number of third through holes 121 is not limited in this example. In this example, other fixing methods can also be used to fix the mounting pressing plate on the workbench, such as bayonet fixing. In this example, by vertically connecting the second horizontal plate and the third horizontal plate through the connecting plate and passing through the through hole on the third horizontal plate to place the mounting pressing plate on the workbench, the mounting pressing plate is stably fixed on the workbench, further enabling the joint flange on the mounting pressing plate to be stably fixed, improving the reliability of the connection between the threaded valve and the joint flange, and thus improving the installation efficiency.

[0052] Figure 2 This is another structural schematic diagram of the disassembly and assembly tooling of the present application; as Figure 2As shown, the first cross plate 100 is provided with a first through hole 102, the second cross plate 110 is provided with a second through hole 111, and the first through hole 102 and the second through hole 111 correspond to each other; the third cross plate 120 is provided with a third through hole 121 for fixing the mounting pressing plate to the workbench.

[0053] Further, after the aforementioned first fixing member passes through the first through hole 102, the first bolt hole, and the second through hole 111, the first fixing member passes through the second cross plate 110 and is exposed. To prevent the first fixing member from falling off, correspondingly, as an example, the third cross plate 120 further includes: a support column 140; the support column 140 is vertically fixed to the third cross plate 120, and the support column 140 is located directly below the first fixing member for supporting the first fixing member.

[0054] Specifically, in this example, the third cross plate 120 of the mounting pressing plate is further provided with a support column 140, and the support column 140 is vertically fixed above the third cross plate 120; the support column 140 is located directly below the first fixing member for supporting the first fixing member to prevent the first fixing member from falling off. The number of support columns 140 in this example corresponds to the number of first fixing members, and the number of support columns 140 in this example is not limited. In this example, by providing a support column on the third cross plate to support the first fastener, the reliability of the joint flange installed on the mounting pressing plate is further increased, and the installation efficiency is improved.

[0055] Specifically, the joint flange 20 needs to be fixed by a first fixing member. Correspondingly, as an example, the number of first fixing members is multiple.

[0056] The first fixing member is a fixed pin, and the fixed pin passes through the first through hole 102, the first bolt hole on the flange 200, and the second through hole 111 to fixedly install the joint flange 20.

[0057] The number of first fixing members in this example is multiple, and the number is not limited. The number of multiple first fixing members is the same as the number of first through holes in each group; multiple first fixing members pass through the first through hole 102 in each group to fix the joint flange 20. The first fixing member in this example is a fixed pin, and the fixed pin passes through the first through hole 102 on the first cross plate 100, the first bolt hole on the flange 200 of the joint flange 20, and the second through hole 111 on the second cross plate 110 to fixedly install the joint flange 20. In this example, multiple fixed pins are used to fixedly install the joint flange to the mounting pressing plate, so that the joint flange is stably fixed to the mounting pressing plate, the reliability of the connection between the threaded valve and the joint flange is improved, and the installation efficiency of the joint flange and the threaded valve is thus improved.

[0058] Further, the disassembly and assembly tooling of the present application further includes: a centering ruler 150;

[0059] The centering ruler has a chassis, and the chassis is vertically connected to the bottom end of the centering ruler 150; the chassis is detachably connected to the mounting pressing plate or the flange plate so that the centering ruler 150 is perpendicular to the first cross plate 100 and the second cross plate 110.

[0060] Specifically, the disassembly and assembly tooling further includes a centering ruler 150, and the centering ruler 150 is detachably connected to the mounting pressing plate or the flange plate 200; the centering ruler 150 has a chassis, and the chassis is vertically connected to the bottom end of the centering ruler 150; the centering ruler 150 is perpendicular to the first cross plate 100 and the second cross plate 110. In practical applications, the threaded valve 30 has a valve handle 300; after the joint flange 20 is connected to the threaded valve 30, the centering ruler 150 can be used to detect whether the valve handle 300 of the threaded valve 30 is parallel to the centering ruler 150, so as to measure whether the valve handle 300 is vertical; when the centering ruler 150 detects that the valve handle 300 is not in the vertical position, the position of the threaded valve 30 can be adjusted accordingly so that the threaded valve 30 is in the vertical position. In this example, using the centering ruler to measure whether the valve handle of the threaded valve is in the vertical position further improves the reliability of the connection between the joint flange and the threaded valve and improves the installation efficiency of the threaded valve and the joint flange.

[0061] In one example, the size of the first cross plate 100 is smaller than the size of the second cross plate 110 so as to expose at least one second bolt hole of the flange plate 200; the chassis is provided with a first connection hole, and the first connection hole corresponds to the second bolt hole; the second fixing member passes through the first connection hole and the second bolt hole to fixedly install the centering ruler 150 to the flange plate.

[0062] In this example, the centering ruler 150 is installed on the flange plate 200 of the joint flange 20 that has been installed on the mounting pressing plate; specifically, the size of the first cross plate 100 is smaller than the size of the second cross plate 110 so that at least one second bolt hole of the flange plate 200 is exposed. The chassis of the centering ruler 150 is provided with a first connection hole, and the first connection hole corresponds to the second bolt hole of the flange plate 200; at this time, the second fixing member passes through the first connection hole and the second bolt hole to fixedly install the centering ruler 150 to the flange plate 200.

[0063] Figure 3 This is another structural schematic diagram of the disassembly and assembly tooling of the present application; as Figure 3 shown, in combination with the foregoing example, the centering ruler 150 is installed on the flange plate 200 of the joint flange 20 that has been installed on the mounting pressing plate; the chassis of the centering ruler 150 is provided with a first connection hole, and the first connection hole corresponds to the second bolt hole of the flange plate 200; the second fixing member passes through the first connection hole and the second bolt hole to fixedly install the centering ruler 150 to the flange plate 200.

[0064] In yet another example, the chassis is provided with a second connection hole; the second connection hole corresponds to the first through hole, and the second fixing member passes through the second connection hole and the first through hole 102 to fixedly install the centering ruler 150 to the first cross plate 100.

[0065] In this example, the centering ruler 150 is installed on the first cross plate 100; specifically, the chassis of the centering ruler 150 is provided with a second connection hole; the second connection hole corresponds to the aforementioned first through hole 102; at this time, the second fixing member passes through the second connection hole and the first through hole 102 to install the centering ruler 150 on the first cross plate 100.

[0066] Combining the above two examples, it should be noted that the type of the second fixing member is not limited, and the number of the second fasteners is multiple. In addition to measuring whether the valve handle 300 of the threaded valve 30 is vertical as described above, the centering ruler 150 of this solution is further used to measure whether the valve handle 300 and the centering ruler 150 are on the same straight line; thereby determining whether the position where the threaded valve 30 is installed on the joint flange 20 is centered. Further improves the reliability of the installation of the joint flange and the threaded valve, and improves the installation efficiency of the joint flange and the threaded valve.

[0067] The disassembly and assembly tooling of the present application includes: an installation pressing plate; the joint flange includes a flange plate and a flange pipe; the flange plate and the flange pipe are integrally connected; the installation pressing plate includes a first cross plate and a second cross plate arranged in parallel; a first space is formed between the first cross plate and the second cross plate for installing the flange plate of the joint flange, and the second cross plate supports the flange plate; the first cross plate is provided with a first opening to embed the flange pipe of the joint flange; the joint flange is detachably connected to the installation pressing plate through a first fixing member; the joint flange is used for threaded connection with the threaded valve. The solution of the present application, by arranging the parallel first cross plate and the second cross plate, and forming a space between the first cross plate and the second cross plate to install the interface flange; and fixing it through a fixing member, and then connecting the fixed joint flange with the threaded valve.
