[0031] Schematic diagram of an integrally sealed oil pipe, see Figures 2 to 6 According to a preferred embodiment of the present invention, an integrated sealed oil pipe includes an oil pipe body 10, a quick-install gasket 20 and a hollow bolt 30.

[0032] Specifically, if Figure 3 and Figure 4As shown, one end of the oil pipe body 10 has an annular joint 101 and an oil delivery chamber 102, the annular joint 101 has a first through-hole 1011, and the oil delivery chamber 102 is connected to the first through-hole 1011. The quick-release gasket 20 includes two gasket parts 201 and a connecting part 202. The connecting part 202 is located between the two gasket parts 201 in the thickness direction of the annular joint 101, and the two ends of the connecting part 202 are respectively spaced a predetermined distance from the two gasket parts 201. Both gasket parts 201 have a second through-hole 2011. The hollow bolt 30 has a circulation chamber 301. One end of the hollow bolt 30 passes through the first through-hole 1011 and each of the second through-holes 2011, and the circulation chamber 301 is connected to the oil delivery chamber 102.

[0033] It should be noted that, during assembly, it is only necessary to place the quick-release gasket 20 directly close to the annular joint 101, and make the two gasket parts 201 respectively abut against the two sides of the annular joint 101. Then, the end of the hollow bolt 30 with the opening of the flow cavity 301 is passed through the gasket part 201 and the first through hole 1011, and the nut part of the hollow bolt 30 is abutted against one of the gasket parts 201. At this time, the flow cavity 301 of the hollow bolt 30 is connected to the oil delivery cavity 102. It is easy to see that In the above-mentioned assembly process, compared with the prior art which requires assembling two gaskets separately, the embodiment of the present application connects the two gasket parts 201 into one body through the connecting part 202. During assembly, the sealing of both sides of the annular joint 101 can be completed with one installation. In addition, by connecting the two gasket parts 201 into one body, limiting any one of the gasket parts 201 will also limit the other gasket part 201 at the same time, which has the advantages of better stability and sealing both sides of the annular joint 101 at the same time, thereby helping to improve assembly efficiency.

[0034] Furthermore, in order to improve the stability of the quick-install gasket 20, as Figure 3 and Figure 5 As shown, the quick-release gasket 20 further includes a tightening portion 203, which extends outward from one side of the gasket portion 201 by a predetermined distance. The tightening portion 203 has two bent ends 2031. When the second through hole 2011 is opposite to the first through hole 1011, the two bent ends 2031 are bent at a predetermined angle and fit against the side wall of the oil pipe body 10.

[0035] It should be noted that the two bent ends 2031 are initially arranged horizontally. When the two gasket portions 201 abut against the two surfaces of the annular joint 101 and the bent ends 2031 are located on one side of the oil pipe body 10, a downward force is applied to the two bent ends 2031, and the two bent ends 2031 are bent toward the oil pipe body 10 until the bent ends 2031 are in contact with the side surfaces of the oil pipe body 10. Then, the two bent ends 2031 are formed into a ring as a whole and clamp the oil pipe body 10, thereby improving the overall stability of the quick-release gasket 20.

[0036] Furthermore, the first through hole 1011 is a stepped hole, and the maximum radial dimension of one end of the hollow bolt 30 close to the opening of the flow cavity 301 is equal to the aperture of the smaller hole of the first through hole 1011 .

[0037] In addition, in the embodiment of the present application, the flow cavity 301 has two flow inlets and one flow outlet (not marked in the figure), and the flow outlet is the cavity opening of the flow cavity 301.

[0038] It should be noted that, when the end of the hollow bolt 30 having the outflow port passes through the first through hole 1011 and the second through hole 2011, since the maximum radial dimension of the end of the hollow bolt 30 close to the opening of the circulation chamber 301 is equal to the aperture of the smaller hole of the first through hole 1011, the hole wall of the first through hole 1011 and the side surface of the bolt body of the hollow bolt 30 jointly form an annular chamber, and the oil flows out from the oil delivery chamber 102 and flows into this annular chamber, and then flows from this annular chamber along the two inflow ports into the circulation chamber 301 and flows out from the outflow port.

[0039] Furthermore, in order to improve the sealing performance of the other end of the oil pipe body 10, Figure 6 As shown, a long joint 103 is provided at one end of the oil pipe body 10 away from the annular joint 101 . The middle section of the long joint 103 has an annular groove 1031 , and a sealing ring 1032 is sleeved in the annular groove 1031 .

[0040] In addition, the center of the long joint 103 has a third through hole (not marked in the figure), and the long joint 103 is fixedly connected to the oil pipe body 10, and its fixed connection method includes but is not limited to welding, and the third through hole is connected to the oil delivery cavity 102.

[0041] It should be noted that the oil can flow along the third through hole to the oil delivery cavity 102. It should also be noted that when the long joint 103 is connected to the external pipeline, the long joint 103 is inserted into the hole of the external pipeline, and the sealing ring 1032 fits against the hole wall of the external pipeline.

[0042] Furthermore, in order to ensure that the length of the long connector 103 extending into the external pipeline can be visually confirmed, as shown in FIG. Figure 6 As shown, the end of the long joint 103 close to the oil pipe body 10 has a supporting portion 1034 , and the maximum radial dimension of the supporting portion 1034 is greater than the maximum radial dimension of the other end of the long joint 103 .

[0043] It should be noted that, when the long connector 103 is inserted into the external pipeline by a predetermined distance, the abutting portion 1034 abuts against the end of the external pipeline.

[0044] Furthermore, to facilitate the insertion of the long connector 103 , the end of the long connector 103 away from the abutting portion 1034 has a chamfer.

[0045] Furthermore, in the embodiment of the present application, the quick-release gasket 20 is made of metal, but because of its thin thickness, during assembly, the quick-release gasket 20 is allowed to deform to a certain extent after being subjected to force. In order to improve the passability of the quick-release gasket 20 when it is close to the annular joint 101, as shown in FIG. Figure 4 and Figure 5 As shown, the connecting portion 202 is C-shaped, so that when the two gasket portions 201 come into contact with the annular joint 101 and encounter resistance, the two gasket portions 201 can be slightly deformed outward.

[0046] Furthermore, in order to make the oil pipe body 10 have good high temperature resistance and corrosion resistance, in the embodiment of the present application, the material of the oil pipe body 10 is 304 stainless steel.

[0047] In summary, the integrally sealed oil pipe according to the embodiment of the present application is explained, which provides the integrally sealed oil pipe with advantages such as simultaneous sealing of both sides of the annular joint, which helps to improve assembly efficiency.

[0048] It is worth noting that the integrated sealed oil pipe in the embodiments of this application has a simple structure, does not involve complex manufacturing processes and does not require expensive materials, and is highly economical. Furthermore, for manufacturers, the integrated sealed oil pipe provided in this application is easy to produce and is low-cost, which is more conducive to controlling production costs and further promoting product promotion and use.

[0049] Those skilled in the art will appreciate that the embodiments of the present invention described above and shown in the accompanying drawings are provided for illustrative purposes only and are not intended to limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functional and structural principles of the present invention have been demonstrated and illustrated in the embodiments.
