Description

Technical Field

[0001] This utility model relates to the field of sealing technology for tee fittings, and in particular to a sealing device for a jacketed high-pressure seamless eccentric tee fitting. Background Technology

[0002] Jacketed high-pressure seamless eccentric tee fittings are special-purpose fittings used in industrial piping systems. The jacketed design typically involves adding a sleeve to the outer layer of the tee fitting, creating a certain space between the jacket and the inner pipe. This space allows for the introduction of heating or cooling media (e.g., steam, hot water, cooling water) to heat or cool the fluid in the inner pipe, achieving precise temperature control during the process. In use, the jacketed high-pressure seamless eccentric tee fitting needs to be connected to connecting pipe fittings. Ensuring a tight seal between the jacketed high-pressure seamless eccentric tee fitting and the connecting pipe fitting is crucial. Therefore, a sealing device for jacketed high-pressure seamless eccentric tee fittings is urgently needed.

[0003] Currently, the three sealing parts of the tee fitting sealing device function independently without mutual constraint. Under such operation, each sealing part is prone to loosening due to vibration, which will affect the sealing effect of the jacketed high-pressure seamless eccentric tee fitting. Utility Model Content

[0004] To address the shortcomings of the existing production technology, the applicant provides a sealing device for a jacketed high-pressure seamless eccentric tee pipe fitting. By improving the structure of the sealing device, the three sealing components of the tee pipe fitting are mutually constrained, thereby improving the sealing effect of the jacketed high-pressure seamless eccentric tee pipe fitting.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A sealing device for a jacketed high-pressure seamless eccentric tee pipe fitting includes: three sealing connection mechanisms and three telescopic rods. The three sealing connection mechanisms are respectively installed at the three ends of the jacketed high-pressure seamless eccentric tee pipe fitting and are used for sealing connections between the three ends of the tee pipe fitting and the three connecting pipe fittings. Each sealing connection mechanism includes: an inner sealing connection part and an outer sealing connection part. The inner sealing connection part is embedded in the outer sealing connection part and connected to the outer sealing connection part. The inner sealing connection part is used for sealing connections between the inner pipe of the tee pipe fitting and the connecting pipe fittings. The outer sealing connection part is used for sealing connections between the jacket of the tee pipe fitting and the connecting pipe fittings. Adjacent outer sealing connection parts are connected by the telescopic rods, and the outer sealing connection parts are hinged to the telescopic rods.

[0007] Therefore, a telescopic rod is hinged between two adjacent outer sealing connections to allow them to be mutually constrained. Compared to the existing sealing method where three sealing components act independently, this method is simpler in structure and easier to operate. The mutual constraint between the three sealing connections can prevent loosening due to vibration of the jacketed high-pressure seamless eccentric tee fitting, thereby improving the sealing effect of the jacketed high-pressure seamless eccentric tee fitting.

[0008] As a further improvement to the above technical solution: the telescopic rod includes a sleeve rod, a sliding rod, and a locking part. One end of the sleeve rod is hinged to one of the external sealing connection parts, and one end of the sliding rod is hinged to another external sealing connection part. The other end of the sliding rod is inserted into the other end of the sleeve rod and slidably connected to the sleeve rod. The locking part passes through the sleeve rod and is threadedly connected to the sleeve rod. The sliding rod is used to control the telescopic movement of the sliding rod relative to the sleeve rod. Therefore, during connection, the locking part and the sliding rod do not abut against each other, allowing the sliding rod to slide relative to the sleeve rod, adjusting the position of the sealing connection mechanism relative to the tee fitting and the connecting fitting, facilitating the installation and disassembly of the tee fitting and the connecting fitting. During sealing, the locking part abuts against the sliding rod, preventing the sliding rod from sliding relative to the sleeve rod, thus constraining the relative movement between two adjacent external sealing connection parts, ensuring that the external sealing connection parts do not loosen, and improving the sealing effect of the jacketed high-pressure seamless eccentric tee fitting.

[0009] As a further improvement to the above technical solution: the inner sealing connection includes an inner connecting block, a mounting groove, and a sealing gasket. One end of the inner connecting block is connected to the inner tube of the tee fitting. The mounting groove is located at the other end of the inner connecting block. The sealing gasket is embedded in the mounting groove. The connecting pipe fitting is inserted into the mounting groove to connect with the inner tube of the tee fitting. Therefore, the sealing effect between the inner tube of the tee fitting and the connecting pipe fitting can be improved by using the sealing gasket.

[0010] As a further improvement to the above technical solution: the external sealing connection includes an annular connecting block, an outer connecting block, and a sealing part. One end of the annular connecting block is connected to the sleeve of the tee fitting. The outer connecting block is sleeved outside the annular connecting block and the tee fitting sleeve, and is slidably connected to the annular connecting block and the tee fitting sleeve. The sealing part is installed at the other end of the annular connecting block. Thus, the sealing effect between the tee fitting sleeve and the connecting pipe can be improved through the sealing part. Furthermore, the slidable connection between the outer connecting block and the annular connecting block and the tee fitting sleeve allows the outer connecting block to slide relative to the annular connecting block and the tee fitting sleeve. The external sealing connection has sufficient space for the installation of the inner sealing connection, without interfering with the installation and disassembly of the inner pipe of the tee fitting and the connecting pipe.

[0011] As a further improvement to the above technical solution: the sealing part includes an annular connecting piece and an air bladder. The annular connecting piece is located at the other end of the annular connecting block, and the air bladder is installed at the end of the annular connecting piece away from the annular connecting block. Therefore, during sealing, the connecting pipe can compress the air bladder, making the connection between the connecting pipe and the annular connecting block more tightly fitted, thus preventing leakage of the heating or cooling medium and improving the sealing effect between the tee fitting jacket and the connecting pipe.

[0012] As a further improvement to the above technical solution, it also includes a support block, wherein the inner sealing connection part and the outer sealing connection part are connected through the support block.

[0013] As a further improvement to the above technical solution, it also includes: a first connecting mechanism, wherein the inner sealing connection part is connected to the connecting pipe through the first connecting mechanism.

[0014] As a further improvement to the above technical solution: the first connecting mechanism includes: a first plug block, a first plug groove, and a first locking member. The first plug block is installed on the outer wall of the connecting pipe, the first plug groove is formed on the inner sealing connection part, the first plug block is adapted to the first plug groove, and the first locking member passes through the inner sealing connection part and is threadedly connected to the inner sealing connection part. Multiple first plug blocks are provided, and the number of first plug grooves and the number of first locking members are equal to the number of first plug blocks. When the first plug block is inserted into the first plug groove, the first locking member is inserted into the first plug block to realize the connection between the inner sealing connection part and the connecting pipe. Therefore, during sealing, the first plug block is inserted into the first plug groove, and the first locking member is inserted into the first plug block to achieve the fixed installation of the inner sealing connection and the connecting pipe fitting. This can prevent loosening due to the vibration of the jacketed high-pressure seamless eccentric tee pipe fitting, thereby improving the sealing effect of the jacketed high-pressure seamless eccentric tee pipe fitting. The design of multiple first plug blocks and multiple first plug grooves can prevent relative rotation between the tee pipe fitting and the connecting pipe fitting.

[0015] As a further improvement to the above technical solution, it also includes a second connecting mechanism, wherein the outer sealing connection part is connected to the connecting pipe through the second connecting mechanism.

[0016] As a further improvement to the above technical solution: the second connecting mechanism includes: a second plug block, a second plug groove, and a second locking member. The second plug block is installed on the outer wall of the connecting pipe, the second plug groove is formed on the outer sealing connection part, the second plug block is adapted to the second plug groove, and the second locking member passes through the outer sealing connection part and is threadedly connected to the outer sealing connection part. Multiple second plug blocks are provided, and the number of second plug grooves and the number of second locking members are equal to the number of second plug blocks. When the second plug block is inserted into the second plug groove, the second locking member is inserted into the second plug block to realize the connection between the outer sealing connection part and the connecting pipe. Therefore, during sealing, the second plug block is inserted into the second plug groove, and the second locking member is inserted into the second plug block to achieve fixed installation of the outer sealing connection and the connecting pipe fitting. This can prevent loosening due to vibration of the jacketed high-pressure seamless eccentric tee pipe fitting, thereby improving the sealing effect of the jacketed high-pressure seamless eccentric tee pipe fitting. The design of multiple second plug blocks and multiple second plug grooves can prevent relative rotation between the tee pipe fitting and the connecting pipe fitting.

[0017] The beneficial effects of this utility model are as follows:

[0018] A telescopic rod is hinged between two adjacent outer sealing connections to allow them to be mutually constrained. Compared to the existing sealing method where three sealing components act independently, this method is simpler in structure and easier to operate. The mutual constraint between the three sealing connections can prevent loosening due to vibration of the jacketed high-pressure seamless eccentric tee fitting, thereby improving the sealing effect of the jacketed high-pressure seamless eccentric tee fitting.

[0019] This utility model also has the following advantages:

[0020] 1. In this utility model, when connected, the locking part does not abut against the sliding rod, so the sliding rod can slide relative to the sleeve rod, which can adjust the position of the sealing connection mechanism relative to the tee fitting and the connecting fitting, so as to facilitate the installation and disassembly of the tee fitting and the connecting fitting; when sealing, the locking part abuts against the sliding rod, so the sliding rod cannot slide relative to the sleeve rod, which can restrain the relative movement between two adjacent outer sealing connection parts, so as to ensure that the outer sealing connection parts will not loosen, thereby improving the sealing effect of the jacketed high-pressure seamless eccentric tee fitting.

[0021] 2. When sealing, the connecting pipe can compress the air bladder, so that the connecting pipe and the annular connecting block fit more tightly, so as to avoid leakage of heating or cooling medium, thereby improving the sealing effect between the tee fitting jacket and the connecting pipe.

[0044] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0045] like Figures 1 to 10 The diagram shows the preferred embodiment of this utility model. The sealing device for the jacketed high-pressure seamless eccentric tee fitting in this embodiment includes: three sealing connection mechanisms 1 and three telescopic rods 4. The three sealing connection mechanisms 1 are respectively installed at the three ends of the jacketed high-pressure seamless eccentric tee fitting and are respectively used for sealing connection between the three ends of the tee fitting and the three connecting fittings. Each sealing connection mechanism 1 includes: an inner sealing connection part 2 and an outer sealing connection part 3. The inner sealing connection part 2 is embedded in the outer sealing connection part 3 and connected to the outer sealing connection part 3. The inner sealing connection part 2 is used for sealing connection between the inner pipe of the tee fitting and the connecting fitting. The outer sealing connection part 3 is used for sealing connection between the jacket of the tee fitting and the connecting fitting. Adjacent two outer sealing connection parts 3 are connected by telescopic rods 4, and the outer sealing connection part 3 and the telescopic rods 4 are hinged. Therefore, a telescopic rod 4 is hinged between two adjacent outer sealing connection parts 3, so that the two adjacent outer sealing connection parts 3 are mutually constrained by the telescopic rod 4. Compared with the existing sealing method in which the three sealing parts 303 act independently, this method has a simple structure and is easy to operate. The mutual constraint between the three sealing connection parts can prevent loosening due to the vibration of the high pressure seamless eccentric tee fitting for jacket, thereby improving the sealing effect of the high pressure seamless eccentric tee fitting for jacket.

[0046] In other words, the jacketed high-pressure seamless eccentric tee fitting is prone to vibration during use. By using three telescopic rods 4, the three sealing connection mechanisms 1 can be mutually constrained, thereby strengthening the constraint effect between the three sealing connection mechanisms 1 (i.e., the three sealing connection mechanisms 1 cannot move independently). In this way, each sealing connection mechanism 1 will not loosen due to the vibration of the tee fitting, thereby improving the sealing effect of the jacketed high-pressure seamless eccentric tee fitting.

[0047] In this embodiment, the telescopic rod 4 includes: a sleeve rod 401, a sliding rod 402, and a locking part 403. One end of the sleeve rod 401 is hinged to an outer sealing connection part 3, and one end of the sliding rod 402 is hinged to another outer sealing connection part 3. The other end of the sliding rod 402 is inserted into the other end of the sleeve rod 401 and is slidably connected to the sleeve rod 401. The locking part 403 passes through the sleeve rod 401 and is threadedly connected to the sleeve rod 401. The sliding rod 402 is used to control the telescopic movement of the sliding rod 402 relative to the sleeve rod 401. Therefore, during connection, the locking part 403 does not abut against the slide rod 402, allowing the slide rod 402 to slide relative to the sleeve rod 401. This allows adjustment of the position of the sealing connection mechanism 1 relative to the tee fitting and the connecting fitting, facilitating the installation and disassembly of the tee fitting and the connecting fitting. During sealing, the locking part 403 abuts against the slide rod 402, preventing the slide rod 402 from sliding relative to the sleeve rod 401. This restrains the relative movement between two adjacent outer sealing connection parts 3, ensuring that the outer sealing connection parts 3 do not loosen, thereby improving the sealing effect of the jacketed high-pressure seamless eccentric tee fitting.

[0048] Specifically, one end of the sleeve rod 401 is hinged to the outer connecting block 302, and one end of the slide rod 402 is hinged to the outer connecting block 302.

[0049] For example, the locking part 403 uses bolts.

[0050] In this embodiment, the inner sealing connection part 2 includes: an inner connecting block 201, a mounting groove 202, and a sealing gasket 203. One end of the inner connecting block 201 is connected to the inner tube of the tee fitting, the mounting groove 202 is formed at the other end of the inner connecting block 201, and the sealing gasket 203 is embedded in the mounting groove 202. The connecting pipe fitting is inserted into the mounting groove 202 so that the connecting pipe fitting is connected to the inner tube of the tee fitting. Thus, the sealing effect between the inner tube of the tee fitting and the connecting pipe fitting can be improved by the sealing gasket 203.

[0051] In this embodiment, the outer sealing connection part 3 includes: an annular connecting block 301, an outer connecting block 302, and a sealing part 303. One end of the annular connecting block 301 is connected to the sleeve of the tee fitting. The outer connecting block 302 is sleeved on the outside of the annular connecting block 301 and the sleeve of the tee fitting, and is slidably connected to the annular connecting block 301 and the sleeve of the tee fitting. The sealing part 303 is installed at the other end of the annular connecting block 301. The sealing part 303 includes: an annular connecting piece 3031 and an airbag 3032. The annular connecting piece 3031 is located at the other end of the annular connecting block 301, and the airbag 3032 is installed at the end of the annular connecting piece 3031 away from the annular connecting block 301. Therefore, the sealing part 303 can improve the sealing effect between the tee fitting jacket and the connecting pipe fitting; in addition, the connection method of the outer connecting block 302 slidingly connecting the annular connecting block 301 and the tee fitting jacket allows the outer connecting block 302 to slide relative to the annular connecting block 301 and the tee fitting jacket, and the outer sealing connection part 3 has enough space (that is, when operating the inner sealing connection part 2, the outer sealing connection part 3 can move closer to the tee fitting to generate clearance space) for the installation of the inner sealing connection part 2, without interfering with the installation and disassembly between the inner pipe of the tee fitting and the connecting pipe fitting; during sealing, the connecting pipe fitting can squeeze the air bag 3032, so that the connecting pipe fitting and the annular connecting block 301 fit more tightly, so as to avoid leakage of heating or cooling medium, thereby improving the sealing effect between the tee fitting jacket and the connecting pipe fitting.

[0052] In this embodiment, it also includes: a support block 5, and the inner sealing connection part 2 and the outer sealing connection part 3 are connected through the support block 5.

[0053] In this embodiment, it further includes: a first connecting mechanism 6, through which the inner sealing connection part 2 is connected to the connecting pipe fitting; the first connecting mechanism 6 includes: a first insertion block 601, a first insertion groove 602, and a first locking member 603. The first insertion block 601 is installed on the outer wall of the connecting pipe fitting, the first insertion groove 602 is formed on the inner sealing connection part 2, the first insertion block 601 is adapted to the first insertion groove 602, and the first locking member 603 penetrates the inner sealing connection part 2 and is threadedly connected to the inner sealing connection part 2; multiple first insertion blocks 601 are provided, and the number of first insertion grooves 602 and the number of first locking members 603 are equal to the number of first insertion blocks 601; when the first insertion block 601 is inserted into the first insertion groove 602, the first locking member 603 is inserted into the first insertion block 601, so as to realize the connection between the inner sealing connection part 2 and the connecting pipe fitting. Therefore, during sealing, the first plug-in block 601 is inserted into the first plug-in groove 602, and the first locking member 603 is inserted into the first plug-in block 601 to achieve the fixed installation of the inner sealing connection part 2 and the connecting pipe fitting. This can prevent loosening due to the vibration of the jacketed high-pressure seamless eccentric tee pipe fitting, thereby improving the sealing effect of the jacketed high-pressure seamless eccentric tee pipe fitting. The design of multiple first plug-in blocks 601 and multiple first plug-in grooves 602 can prevent relative rotation between the tee pipe fitting and the connecting pipe fitting.

[0054] Specifically, the first insertion slot 602 is formed on the inner connecting block 201, and the first locking member 603 passes through the inner connecting block 201.

[0055] For example, the first locking part 403 uses bolts.

[0056] In this embodiment, a second connecting mechanism 7 is also included. The outer sealing connection part 3 is connected to the connecting pipe through the second connecting mechanism 7. The second connecting mechanism 7 includes a second insertion block 701, a second insertion groove 702, and a second locking member 703. The second insertion block 701 is installed on the outer wall of the connecting pipe, and the second insertion groove 702 is formed on the outer sealing connection part 3. The second insertion block 701 and the second insertion groove 702 are adapted to each other. The second locking member 703 passes through the outer sealing connection part 3 and is threadedly connected to the outer sealing connection part 3. Multiple second insertion blocks 701 are provided. The number of second insertion grooves 702 and the number of second locking members 703 are equal to the number of second insertion blocks 701. When the second insertion block 701 is inserted into the second insertion groove 702, the second locking member 703 is inserted into the second insertion block 701 to realize the connection between the outer sealing connection part 3 and the connecting pipe. Therefore, during sealing, the second plug block 701 is inserted into the second plug groove 702, and the second locking member 703 is inserted into the second plug block 701 to achieve fixed installation of the outer sealing connection part 3 and the connecting pipe fitting. This can prevent loosening due to the vibration of the jacketed high-pressure seamless eccentric tee pipe fitting, thereby improving the sealing effect of the jacketed high-pressure seamless eccentric tee pipe fitting. The design of multiple second plug blocks 701 and multiple second plug grooves 702 can prevent relative rotation between the tee pipe fitting and the connecting pipe fitting.

[0057] Specifically, the second insertion slot 702 is formed on the outer connecting block 302, and the second locking member 703 passes through the outer connecting block 302.

[0058] For example, the second locking part 403 uses bolts.

[0059] The connection process of this utility model for a jacketed high-pressure seamless eccentric tee fitting is as follows: First, rotate and loosen the locking part 403 so that the sliding rod 402 can move relative to the sleeve rod 401, and move the outer connecting block 302 closer to the tee fitting; next, insert the connecting fitting into the mounting groove 202, and use the first connecting mechanism 6 to achieve fixed installation between the connecting fitting and the inner connecting block 201, thereby achieving fixed installation between the connecting fitting and the inner tube of the tee fitting, and use the sealing gasket 203 to achieve sealing between the connecting fitting and the inner tube of the tee fitting; then, move the outer connecting block 302 away from the tee fitting, and use the second connecting mechanism 7 to... The connecting pipe fitting and the outer connecting block 302 are fixedly installed to achieve the fixed installation between the connecting pipe fitting and the tee fitting jacket, and the sealing part 303 is used to achieve the seal between the connecting pipe fitting and the tee fitting jacket. Finally, the locking part 403 is rotated and tightened so that the slide rod 402 moves relative to the sleeve rod 401 without contact. The three telescopic rods 4 constrain the three sealing connection mechanisms 1. In addition, during use, the inner pipe of the connecting pipe fitting and the tee fitting is used to transport fluid, and the jacket of the connecting pipe fitting and the tee fitting is used to transport heating or cooling media (e.g., steam, hot water, cooling water) to achieve the heating or cooling treatment of the transported fluid.

[0060] In summary, the present invention has a telescopic rod 4 hinged between two adjacent outer sealing connection parts 3, so that the two adjacent outer sealing connection parts 3 are mutually constrained by the telescopic rod 4. Compared with the existing sealing method in which the three sealing parts 303 act independently, this method has a simple structure and is easy to operate. The mutual constraint between the three sealing connection parts can prevent loosening due to the vibration of the high pressure seamless eccentric tee pipe fitting for jacket, thereby improving the sealing effect of the high pressure seamless eccentric tee pipe fitting for jacket.
