Description

Technical Field

[0001] This utility model relates to the field of long-distance pipeline technology, and in particular to a high-sealing quick-installation ball valve forging assembly for long-distance pipelines. Background Technology

[0002] Long-distance pipelines are industrial pipeline systems used to transport fluid media such as natural gas, fuel oil, and chemicals over long distances. They are classified into two categories based on materials: metallic and non-metallic. Design pressures range from vacuum to ultra-high pressure (up to 100 MPa and above). They are widely used in oil and gas gathering and transportation, urban gas supply, and energy base transportation. The system consists of pipelines, compressor stations, and distribution valve chambers. Construction processes include welding and anti-corrosion treatment. By efficiently and stably transporting energy resources (such as natural gas and crude oil) from production sites to consumption sites, long-distance pipelines effectively alleviate regional energy supply and demand contradictions, reduce transportation risks, and safeguard national energy security strategies.

[0003] The existing technical solutions mentioned above have the following drawbacks: when the existing ball valve forging assembly is connected to the pipeline as a whole, there is a lack of convenient and quick installation methods, and subsequent disassembly and maintenance are inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a high-sealing, quick-installation ball valve forging assembly for long-distance pipelines.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A high-sealing, quick-installation ball valve forging assembly for long-distance pipelines includes a valve body, a connecting pipe installed on the outer side of the valve body, a connecting flange fixedly connected to the outer side of the connecting pipe, an installation bolt inserted into the inner side of the connecting flange, an installation nut threaded onto the outer side of the installation bolt, a pipe provided on the outer side of the connecting pipe, a first connector and a second connector installed on the outer side of the pipe, and a locking bolt inserted into the inner side of the first connector.

[0007] By adopting the above technical solution, a structure for connection via flange is added to the outside of the valve body. At the same time, there is a pipe on the outside of the structure. The pipe and the connecting pipe are combined and installed, so that the pipe that needs to be laid can be installed without adding a flange to the outside of the pipe. It can be directly snapped together and installed, which is convenient for installation and use.

[0008] Furthermore, a first limiting plate is fixedly connected to the inner side of the first connector, and the same first sealing element is fixedly connected to both ends of the first limiting plate on the inner side of the first connector. A first mounting block is fixedly connected to the outer side of the first connector, and a locking block is fixedly connected to the outer side of the first mounting block. The locking block has a through hole inside.

[0009] By adopting the above technical solution, the inner side of the first connector has a limiting plate and a sealing element, which can seal the pipe installed inside, and at the same time facilitate the docking of the pipe and the connecting pipe.

[0010] Furthermore, a second limiting plate is fixedly connected to the inner side of the second connector, and the same second sealing element is fixedly connected to both ends of the second limiting plate on the inner side of the second connector. A second mounting block is fixedly connected to the outer side of the second connector, and the interior of the second mounting block is provided with a slot and a threaded hole.

[0011] By adopting the above technical solution, the inner side of the second connector has the same limiting plate and sealing element, which can seal the connecting pipe of the pipeline and facilitate installation and use.

[0012] Furthermore, one end of both the connecting pipe and the outer side of the pipe is placed inside the first connector and the second connector, and the inner and outer diameters of the connecting pipe and the pipe are the same.

[0013] By adopting the above technical solution, the pipes and connecting pipes can be installed together by combining and splicing the two connectors. At the same time, a sealing treatment can be provided. The installation method of connecting the top and bottom is also very convenient for disassembly later.

[0014] Furthermore, both the first and second connectors adopt a semi-circular structure. The first and second connectors are the same size and have the same specifications. The first and second mounting blocks are in contact with each other. The locking block and the locking slot are engaged. The locking bolt passes through the first and second mounting blocks and extends into the interior of the threaded hole, and is threadedly connected to the threaded hole.

[0015] By adopting the above technical solution, the two sets of connecting parts can be quickly installed through the cooperation of locking bolts and threaded holes, which facilitates disassembly and installation at any time and makes it convenient for later maintenance and use.

[0016] In summary, the beneficial technical effects of this utility model are as follows:

[0017] The system employs connecting pipes, pipes, locking bolts, a first connector, and a second connector. The pipes and connecting pipes are installed using the first and second connectors. The two sets of connectors can seal the connection between the pipes and connecting pipes. The connecting pipes are connected to the valve body via connecting flanges, allowing for quick installation and disassembly. Attached Figure Description
