[0002] With the continuous upgrading of oilfield development technology, skid-mounted water distribution rooms have been widely used for fractional water injection in oilfield injection wells. While skid-mounted water distribution rooms can meet the requirements of fractional water injection, their structural characteristics bring a series of problems to subsequent maintenance. Due to the compact installation and limited operating space—with only 14cm between gate handwheels—cleaning and disassembling the water meter core is inconvenient. The water meter core is installed horizontally into the process flow, and positioning pins ensure concentricity between the meter and the flow flow, making disassembly and cleaning even more difficult. Currently, the common method is to tap it with a small hammer, which can damage the meter counter, cause improper installation, and in severe cases, result in personal injury. To address these issues, it is necessary to design specialized wrenches and water meter core disassembly and assembly tools to overcome the current bottleneck of limited operating space and the risk of personal injury.

[0044] Based on Example 1, this city provides a method for using an integrated tool for disassembling and assembling water meter cores in skid-mounted water installation rooms, and prepares an auxiliary tool, an open-end wrench 20.

[0045] like Figure 1 As shown, when using this tool to disassemble the water meter core, first use the open-end wrench 20 to remove the pressure cap 34, then use the chuck clamp 9 of the chuck body 10 to clamp onto the water meter assembly housing 31. The two ends of the chuck body 10 are fixed with the chuck fastening rod 8 to form a tension point; the front end of the hydraulic plunger 3 is fitted with a small baffle 23 and fixed with a locking nut 24. The first thread 7 of the hydraulic cylinder body 2 is connected to the second thread on the center hole 19 of the support frame body, and then the threaded connector of the connecting rod assembly is connected to the chuck screw hole 12 of the chuck body 10.

[0046] like Figure 2 As shown, when installing the water meter core, the water meter core chuck 9 is engaged with the front end cap 34 of the water meter core 29, forming a tension point for the water meter core. The front end 4 of the hydraulic plunger is fitted with a large baffle 22 and secured with a locking nut 24. The large baffle 22 acts on the rear end of the water meter assembly housing 31 to form a support point. When the support frame is balanced, the handle 1 is pushed back and forth by hand to continuously extend the hydraulic plunger 3. Through the combined action of the connecting support frame and the water meter core chuck, the water meter core 29 is pulled to the right, enters the water meter assembly housing 31 and is installed in place. The cap 34 is then tightened, thus realizing the integrated operation of water meter core disassembly and assembly.

[0047] This invention provides an "integrated tool for disassembling and assembling water meter cores in a pry-and-place machine." The tool mainly consists of four parts: a hydraulic drive assembly, a water meter core chuck, a connecting support frame, and auxiliary components. First, the hydraulic drive assembly features a dedicated hydraulic jack to ensure the required pulling force for disassembling and assembling the water meter core, while also meeting the needs of operation in confined spaces. The jack plunger rod has a T-shaped thread at its front end for docking with the connecting support frame, and a baffle screw hole at its top for docking with baffles of varying sizes. Second, the water meter core chuck is a dedicated chuck designed to secure the water meter core housing during disassembly and the water meter core cap during installation. Third, the connecting support frame is a dedicated connecting support frame for the jack and the water meter core chuck, ensuring a seamless connection between the jack and the chuck. Fourth, the auxiliary components include a dedicated wrench for disassembling and assembling the water meter core cap, and a dedicated "concave" baffle for disassembling and assembling the water meter core to observe whether the keyway is properly installed.

[0048] How to use:

[0049] When disassembling the water meter core, first use an open-end wrench to remove the water meter core pressure cap, then use the water meter core chuck to clamp onto the water meter assembly housing to form a tension point. Install a small baffle at the front end of the hydraulic plunger. The size of the small baffle should be slightly smaller than the mounting hole at the bottom of the water meter core. Connect the support frame to integrate the hydraulic jack and the water meter core chuck. The hydraulic plunger and the small baffle together push the water meter core out of the housing and remove it.

[0050] When installing the water meter core, the water meter core chuck is engaged with the front pressure cap of the water meter core, forming a tension point for the water meter core. A large baffle is installed at the front end of the hydraulic plunger. The bottom area of ​​the large baffle is larger than the bottom mounting hole of the water meter core. The large baffle acts on the rear housing of the water meter core assembly to form a support point. As the hydraulic plunger extends, the water meter core is pulled into the assembly and installed in place by the combined action of the connecting support frame and the water meter core chuck. The pressure cap is then tightened, thus realizing the integrated operation of water meter core installation and removal.

[0051] This method solves the problem of using a small hammer to knock and clean the water meter core, eliminating issues such as damage to the water meter counter and improper installation, shortening operation time, and improving work efficiency.
