[0002] Stainless steel pipe is a pipe made of stainless steel. Stainless steel is an alloy steel whose main components include iron, chromium, nickel, etc. It has excellent corrosion resistance, high temperature resistance and mechanical strength. Stainless steel pipe is widely used in many industries due to its good physical and chemical properties, such as chemical industry, petroleum, food, medicine, construction, aerospace, etc. Stainless steel pipe consists of a pipe body and a containing cavity. The containing cavity is used for medium transmission, so it is very important to improve the thermal insulation performance of the pipe body. Specifically, if the pipeline transports high-temperature media (such as steam, hot oil, etc.), thermal insulation can reduce heat loss, maintain the temperature of the medium, and improve energy utilization efficiency; for transporting low-temperature media (such as liquefied natural gas, refrigerant, etc.), thermal insulation can prevent external heat from entering the pipeline, avoid the medium temperature from rising, and ensure the normal operation of the system.

[0003] Therefore, how to improve the thermal insulation performance of stainless steel pipes has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: it includes a tube body extending axially to the left and right and a accommodating cavity located in the tube body, and also includes a left thermal insulation sleeve and a right thermal insulation sleeve made of thermal insulation material, the left thermal insulation sleeve and the right thermal insulation sleeve are respectively arranged on the left and right sides of the tube body and the left thermal insulation sleeve and the right thermal insulation sleeve are detachably connected, the left side of the left thermal insulation sleeve is detachably connected to the left side of the tube body, and the right side of the right thermal insulation sleeve is detachably connected to the right side of the tube body.

[0006] The utility model is further configured as follows: a plurality of left positioning grooves and right positioning grooves are respectively arranged at intervals along the circumferential direction on the left and right sides of the tube body; the left heat insulation sleeve is provided with a left positioning strip corresponding to each left positioning groove; and the right heat insulation sleeve is provided with a right positioning strip corresponding to each right positioning groove.

[0007] The utility model is further configured as follows: each of the left positioning strips comprises an inner alignment section and an outer installation section, and the width of each alignment section is smaller than the corresponding installation section.

[0008] The utility model is further configured as follows: the left thermal insulation sleeve is provided with a plurality of connecting plugs made of a deformable material protruding to the right, the connecting plugs are arranged at intervals along the circumference of the left thermal insulation sleeve, and the right thermal insulation sleeve is provided with a connecting slot corresponding to each connecting plug.

[0009] The utility model is further configured as follows: each connecting plug includes a fixed section fixedly connected to the left thermal insulation sleeve and a connecting section located on the right side of each fixed section, each fixed section is arranged in a long strip, and each connecting section is arranged in a circular ring shape, and the connecting slot includes a fixing groove corresponding to the fixed section and a connecting groove corresponding to the connecting section.

[0010] The present invention is further configured as follows: the left heat-insulating sleeve includes a fitting section located on the left side, the right end face of the fitting section abuts against the left end face of the tube body, and the fitting section is detachably connected to the tube body.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] like Figures 1-11As shown, the utility model discloses a heat-insulating stainless steel pipe, comprising a pipe body 1 extending axially left and right and a receiving cavity 11 located in the pipe body 1. The pipe body 1 usually plays the role of medium transmission, so the medium / fluid to be transmitted flows into the receiving cavity 11 of the pipe body 1 from one end and flows out toward the other end (this is the prior art and will not be described in detail here). It also includes a left heat-insulating sleeve 2 and a right heat-insulating sleeve 3 made of heat-insulating materials such as aluminum silicate fiber. The left heat-insulating sleeve 2 and the right heat-insulating sleeve 3 are respectively provided with heat-insulating materials such as aluminum silicate fiber and aluminum silicate fiber. The heat-insulating sleeves 3 are respectively sleeved on the left and right sides of the tube body 1, and the left heat-insulating sleeve 2 and the right heat-insulating sleeve 3 are detachably connected by buckling, magnetic attraction, etc. The left side of the left heat-insulating sleeve 2 is detachably connected to the left side of the tube body 1 by buckling, magnetic attraction, etc., and the right side of the right heat-insulating sleeve 3 is detachably connected to the right side of the tube body 1 by buckling, magnetic attraction, etc. Since the left heat-insulating sleeve 2 and the right heat-insulating sleeve 3 are made of heat-insulating material, when the left heat-insulating sleeve 2 and the right heat-insulating sleeve 3 are respectively sleeved on After the left and right sides of the tube body 1 are connected, the left insulation sleeve 2 and the right insulation sleeve 3 are fixed to achieve a stable connection between the left insulation sleeve 2 and the right insulation sleeve 3 and are sleeved on the circumference of the tube body 1. At this time, the left insulation sleeve 2 and the right insulation sleeve 3 can effectively reduce heat conduction and protect the external environment from high temperature. At the same time, they can also protect the internal fluid from the influence of external temperature. Moreover, since the left insulation sleeve 2 is detachably connected to the left side of the tube body 1 and the right insulation sleeve 3 is detachably connected to the right side of the tube body 1, after the left insulation sleeve 2 and the right insulation sleeve 3 are connected, the left insulation sleeve 2 and the right insulation sleeve 3 cannot be rotated compared with the tube body 1, thereby further improving the connection stability with the tube body 1, thereby maintaining the temperature of the fluid and improving the energy utilization efficiency. Moreover, when the left insulation sleeve 2 or the right insulation sleeve 3 needs to be replaced or cleaned, there is no need to dismantle the entire pipeline system. Only the left insulation sleeve 2 and the right insulation sleeve 3 need to be separated and then removed from the left and right sides of the tube body 1.

[0030] Among them, the left and right sides of the tube body 1 are respectively provided with a plurality of left positioning grooves 12 and right positioning grooves 13 at intervals along the circumferential direction, the left thermal insulation sleeve 2 is provided with a left positioning strip 21 corresponding to each left positioning groove 12, and the right thermal insulation sleeve 3 is provided with a right positioning strip 31 corresponding to each right positioning groove 13. Since the tube body 1 is provided with left positioning grooves 12 and right positioning grooves 13 along the circumferential direction, in the process of respectively sleeved the left thermal insulation sleeve 2 and the right thermal insulation sleeve 3 on the tube body 1 circumferentially, when the left positioning strips 21 in the left thermal insulation sleeve 2 are inserted into the corresponding left positioning groove 12, and the right positioning strips 31 of the right thermal insulation sleeve 3 are inserted into the corresponding right positioning groove 13, the left thermal insulation sleeve 2 and the right thermal insulation sleeve 3 cannot be rotated compared with the tube body 1 after the circumferential sleeve of the tube body 1 is completed, thereby providing convenience for the fixed connection of the left thermal insulation sleeve 2 and the right thermal insulation sleeve 3 and the fixation to the tube body 1 respectively.

[0031] Preferably, each of the left positioning strips 21 includes an inner alignment section 211 and an outer installation section 212, and the width of each alignment section 211 is smaller than the corresponding installation section 212. Therefore, in the process of sleevening the left thermal insulation sleeve 2 on the circumferential left side of the tube body 1, the inner alignment section 211 corresponding to the left positioning groove 12 is inserted first. Since the width of the alignment section 211 is smaller than the corresponding installation section 212, each left positioning strip 21 can enter the corresponding left positioning groove 12 more smoothly in the process of sleevening the left thermal insulation sleeve 2 on the left side of the tube body 1.

[0032] Among them, the left thermal insulation sleeve 2 is provided with a number of connecting plugs 22 made of rubber or other easily deformable materials protruding to the right, and each connecting plug 22 is arranged at intervals along the circumference of the left thermal insulation sleeve 2, and the right thermal insulation sleeve 3 is provided with a connecting slot 32 corresponding to each connecting plug 22. After the left thermal insulation sleeve 2 is sleeved on the left side of the tube body 1, the right thermal insulation sleeve 3 is installed from the right side of the tube body 1. Since each right positioning strip 31 will be located in the corresponding right positioning groove 13, the right positioning strip 31 needs to be aligned with each right positioning groove 13 and smoothly installed from right to left. When each connecting groove 322 contacts the connecting plug 22 of the left thermal insulation sleeve 2, each connecting plug 22 will enter the corresponding connecting slot 32, thereby connecting the left thermal insulation sleeve 2 and the right thermal insulation sleeve 3 together.

[0033] Preferably, each connecting plug 22 includes a fixed section 221 fixedly connected to the left heat insulation sleeve 2 by means of integral molding or the like, and a connecting section 222 located on the right side of each fixing section 221. Each fixing section 221 is arranged in a long strip, and each connecting section 222 is arranged in a circular ring shape. The connecting slot 32 includes a fixing groove 321 corresponding to the fixing section 221 and a connecting groove 322 corresponding to the connecting section 222. 1. Since each fixing section 221 is in a long strip and each connecting section 222 is in a circular ring, the connecting plug 22 on the left heat insulation sleeve 2 first enters the connecting slot 32 with the right connecting section 222. Therefore, the connecting section 222 needs to forcibly cross the fixing groove 321 and then be installed in the connecting groove 322. After the connection section 222 and the connecting groove 322 are matched, the fixing section 221 is located at 321, so in the absence of external force, the connecting plug 22 can be stably located in the corresponding connecting slot 32. Similarly, when it is necessary to separate the connecting plug 22 from the corresponding connecting slot 32, it is necessary to apply a rightward force to the right thermal insulation sleeve 3 or a leftward force to the left thermal insulation sleeve 2 so that each connecting section 222 is forced to cross the fixing slot 321 to the left to achieve the separation of the connecting plug 22 from the connecting slot 32; 2. Because each connecting section 222 is annular, that is, hollow inside, when each connecting section 222 crosses the fixing slot 321 to the right and separates the left thermal insulation sleeve 2 and the right thermal insulation sleeve 3, the connecting section 222 can deform toward the internal hollow position and thus cross the fixing slot 321 more smoothly.

[0034] In addition, the left thermal insulation sleeve 2 includes a mating section 23 located on the left side, and the right end face of the mating section 23 is abutted against the left end face of the tube body 1. The mating section 23 and the tube body 1 are detachably connected by snapping, magnetic attraction, etc. After the positions of the left thermal insulation sleeve 2 and the left side of the tube body 1 are determined, the mating section 23 is located on the left side of the tube body 1, and then after the connection between the mating section 23 and the tube body 1 is completed, the connection between the left thermal insulation sleeve 2 and the left side of the tube body 1 can be achieved, so that the left thermal insulation sleeve 2 is stably located on the outer periphery of the tube body 1.

[0035] Preferably, the mating section 23 is provided with a limiting plug 231 protruding to the right and made of a deformable material such as rubber, and a mating groove 2311 is provided on the limiting plug 231. The tube body 1 is provided with a mating slot 14 corresponding to the limiting plug 231, and the tube body 1 is provided with a mating plug 15 located in the mating slot 14. In the process of connecting the mating section 23 with the left side of the tube body 1, the limiting plug 231 needs to forcibly cross the mating plug 15 in the mating slot 14 so that the mating section 23 can be stably connected to the left side of the tube body 1. When the left thermal insulation sleeve 2 needs to be separated from the tube body 1, the separation of the mating block 15 and the mating groove 2311 can be achieved by applying force to the mating section 23 of the left thermal insulation sleeve 2 and causing it to deform toward the left, thereby separating the left side of the left thermal insulation sleeve 2 from the tube body 1.

[0036] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
