Description

Technical Field

[0001] The utility model relates to the technical field of gas pipelines, and in particular to a wrapping protection structure for indoor gas pipelines. Background Art

[0002] A natural gas pipeline refers to a pipeline that transports natural gas (including associated gas produced in oil fields) from the production site or processing plant to urban gas distribution centers or industrial enterprise users. It is also called a gas transmission pipeline. The use of natural gas pipelines to transport natural gas is a way to transport large quantities of natural gas on land. Natural gas pipelines account for about half of the world's total pipeline length.

[0003] Existing indoor gas pipeline wrapping protection structures, for example, Chinese patent application N216896103U discloses an installation structure suitable for household gas pipelines, which records: fixing the fixing base plate to the installation wall by fixing screws, connecting the first gas pipeline and the second gas pipeline by plugging and installing them on the installation interface, closing the upper cover plate and the lower cover plate, tightly closing the upper cover plate and the lower cover plate by bolts and nuts, and then wrapping the joints to prevent gas leakage, fixing the first gas pipeline and the second gas pipeline by anti-slip pads in the upper cover plate and the lower cover plate, and then preventing the first gas pipeline and the second gas pipeline from sliding due to external force.

[0004] When the above-mentioned wrapping protection structure for indoor gas pipelines is in use, since the common sizes of indoor gas pipelines are divided into DN32, DN25, DN20 and DN15, the upper cover plate and the lower cover plate cannot be used to install and protect small gas pipelines. It is necessary to replace the cover plates that match the size of the small gas pipelines for fixing. Too many bolts will cause stress concentration, especially in the cover plate connection area. This stress concentration will cause fatigue failure or fracture of components. A large number of bolts may make the assembly process complicated and difficult, and will also increase assembly time and cost. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model is further described below in conjunction with embodiments.

[0025] Example 1

[0026] Reference Figure 1-2, which is the first embodiment of the utility model, provides a wrapping protection structure for an indoor gas pipeline, which includes a cover body 100, in which a sleeve mechanism 200 is installed, and is suitable for indoor gas pipelines of different sizes. The sleeve mechanism 200 includes a threaded hole 201, an installation interface 202, a limit block 203, a sealing ring 204 and a threaded sleeve 205. The threaded hole 201 is opened in the cover body 100, and the installation interface 202 is installed in the cover body 100. The limit block 203 is fixedly connected in the installation interface 202, the sealing ring 204 is sleeved on both ends of the installation interface 202, and the threaded sleeve 205 is rotatably connected in the cover body 100. When a DN20 gas pipeline is used, it can be directly inserted into the cover body 100. Through the cooperation of the bolt 211 and the nut stacked with the self-locking washer 214, the cover body 100 can be installed and protected for its different large gas pipelines. The setting of the sealing ring 204 can prevent gas leakage, so that the DN20 gas pipelines at both ends can be installed smoothly.

[0027] One end of the threaded sleeve 205 away from the cover body 100 is fixedly connected to a pulse wheel 206, and a threaded hole 201 is engaged on the threaded sleeve 205. When a DN15 gas pipeline is used, it is inserted into the threaded sleeve 205 and fixed. By rotating the pulse wheel 206, the threaded sleeve 205 is rotated along the threaded hole 201 and enters the cover body 100, driving the DN15 gas pipeline to be plugged into the installation interface 202, so that the DN15 gas pipelines at both ends can be installed smoothly.

[0028] During use, the DN15 gas pipe is inserted into the threaded sleeve 205, and the impeller 206 is rotated to make the threaded sleeve 205 rotate along the threaded hole 201 into the cover body 100, thereby driving the DN15 gas pipe to be plugged into the installation interface 202, so that the DN15 gas pipes at both ends can be installed smoothly, thereby providing installation protection for small pipes and increasing the applicability of the equipment.

[0029] Example 2

[0030] Reference Figure 1-4 , which is the second embodiment of the utility model, provides a wrapping protection structure for an indoor gas pipeline, and this wrapping protection structure for an indoor gas pipeline includes a mounting hole 207 opened on the cover plate body 100, and an upper matching block 208 is slidably connected in the mounting hole 207, and a lower matching block 209 is slidably connected on the upper matching block 208. There are six mounting holes 207, which are fixed by the sliding fit of the upper matching block 208 and the lower matching block 209, so that the four middle mounting holes 207 do not need to be fixed with bolts 211 and nuts stacked with self-locking washers 214, thereby reducing the use of bolts 211 and nuts stacked with self-locking washers 214 and reducing the complexity of installation and disassembly.

[0031] Both ends of the upper matching block 208 are provided with fixing holes 210 , and both ends of the lower matching block 209 are provided with fixing holes 210 .

[0032] The lower surface of the lower mating block 209 is provided with an upper stacked self-locking washer 212, and the lower surface of the upper stacked self-locking washer 212 is engaged with a lower stacked self-locking washer 213. The cooperation between the upper stacked self-locking washer 212 and the lower stacked self-locking washer 213 prevents the bolt 211 and the nut stacked self-locking washer 214 from falling off.

[0033] A bolt 211 is provided in the fixing hole 210 , and a lower stacked self-locking washer 213 is sleeved on the bolt 211 , and a nut stacked self-locking washer 214 is rotatably connected to the lower surface of the lower stacked self-locking washer 213 , and the bolt 211 and the nut stacked self-locking washer 214 cooperate to achieve fixation.

[0034] During use, the upper mating block 208 and the lower mating block 209 are slidingly fitted and fixed, so that the four middle mounting holes 207 no longer need to be fixed with bolts 211 and nuts stacked self-locking washers 214, thereby reducing the use of bolts 211 and nuts stacked self-locking washers 214 and reducing the complexity of installation and disassembly. The upper stacked self-locking washers 212 and the lower stacked self-locking washers 213 are fitted to prevent the bolts 211 and nuts stacked self-locking washers 214 from falling off.

[0035] The remaining structure is the same as that of Example 1.
