Description

Technical Field

[0001] The utility model belongs to the technical field of a new type of stainless steel pipe for machinery and structure, and more specifically, particularly relates to a new type of stainless steel pipe for machinery and structure. Background Art

[0002] Stainless steel pipe is a hollow long round steel, which is widely used in industrial pipelines such as petroleum, chemical, medical, food, light industry, mechanical instruments, and mechanical structural parts. This kind of steel is light in weight when the bending and torsional strength are the same, so it is also widely used in the manufacture of mechanical parts and engineering structures. The corrosion resistance of stainless steel pipe depends on the alloy elements contained in the steel, and it can resist corrosion from weak corrosive media such as air, steam, and water, and chemically corrosive media such as acids, alkalis, and salts. Due to its excellent corrosion resistance and light weight, stainless steel pipe plays an important role in many industrial fields.

[0003] Based on the above, the inventors have found the following problems: the existing stainless steel pipes do not have a heat-insulating effect. When liquids that require temperature are transported in stainless steel pipes, sponge and other materials need to be wrapped on the outer layer to achieve heat preservation. The steps are cumbersome and troublesome.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and new stainless steel pipes for machinery and structures are provided, in order to achieve a more practical purpose. Utility Model Content

[0006] A new type of stainless steel pipe for machinery and structure, comprising a main body, an insulation layer, a sealing layer, a protrusion and a connecting ring, wherein connecting rings are provided at both ends of the main body, a sealing layer is provided inside the main body, an insulation layer is provided inside the sealing layer, a protrusion is provided at one end of the insulation layer, a threaded block is provided on the outer surface of the protrusion, a threaded groove is provided at one end of the insulation layer away from the protrusion, a plurality of threaded holes are provided on the connecting ring, bolts are provided in the threaded holes, a fixing assembly is provided on the connecting ring at one end of the main body, and sealing assemblies are provided on the side walls at both ends of the main body.

[0007] Furthermore, the fixing assembly includes a chamber, a rotating member is provided in the chamber, one end of the rotating member passes through the chamber and extends out of the connecting ring to be connected with a threaded cap, and the threaded cap is located on the side of the connecting ring opposite to the position of the protrusion.

[0008] Furthermore, the sealing assembly includes a sealing block, a push piece and a connecting hole, the connecting hole is located on the side walls at both ends of the main body, and a push piece is provided in the connecting hole, the push piece passes through the connecting hole and extends into the sealing layer, and the bottom of the push piece is in contact with the sealing block, the part where the sealing block and the push piece are in contact is an inclined surface, and the other end of the sealing block is flush with the end face of the main body.

[0009] Furthermore, the thermal insulation layer is made of PB pipe material, and a polyurethane foam layer is provided in the thermal insulation layer.

[0010] Furthermore, one end of the sealing block away from the pushing piece is made of silicone rubber.

[0011] Furthermore, one end of the push piece close to the sealing block is arc-shaped, and the push piece is threadedly connected to the connecting hole, and the sealing block moves between the main body and the insulation layer without being separated from the main body.

[0012] Furthermore, the bolt is threadedly connected to the threaded hole and the threaded cap, and the bolt matches the threaded hole and the threaded cap, and the threaded block matches the threaded groove.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The utility model has a rotating part at one end of the threaded cap, and the rotating part is movably arranged on the connecting ring, so that the threaded cap can be prevented from falling off when it is loose, thereby avoiding the loss of the threaded cap, and the rotating part can be flexibly rotated in the chamber, so that it can be installed in coordination with the bolt;

[0015] The push piece is rotated to pass through the connection hole and enter the sealing layer. When the bottom of the rotating piece gradually approaches the bottom of the sealing layer, the side wall of the bottom of the push piece squeezes the sealing block, causing the sealing block to move away from the push piece. Combined with the sealing block at the tail of the other main body, the connection between the main body and the other main body can be sealed.

[0016] The heat preservation effect can be achieved by providing a polyurethane foam layer in the heat preservation layer, and the heat preservation layer is designed as a PB pipe, which can make the heat preservation layer have high temperature resistance, durability, chemical stability, plasticity and long life, thereby improving the service life of the device.
