[0028] The following is combined with Figure 1-3 This application is described in further detail.
[0029] See also Figure 1-3, an oil-water transport sealing structure, including an oil-water exchanger 1, the oil-water exchanger 1 is used for heat exchange with an air compressor, and the oil-water exchanger 1 is composed of a built-in water pipe and an external oil pipe. The side walls of the oil-water exchanger 1 are fixedly connected with joints 2 for oil and water, wherein there are four joints 2, which are respectively for oil input and output, and water input and output. The joints 2 are connected with connecting pipes 3, which are used to transport oil or water. The side wall fixing ring of the connecting pipe 3 is provided with a sealing ring 4, and a sealing ring 5 is fixedly connected to one side of the sealing ring 4, and the sealing ring 4 is in contact with the joint 2 through the sealing ring 5. The connecting pipe 3 is installed with a fixing part, which is used to connect and fix with the joint 2. An anti-drip component is installed at the connecting pipe 3 and the joint 2.
[0030] When connecting the connecting pipe 3 to the joint 2, the connecting pipe 3 is first pressed against the joint 2 using the sealing ring 5, and then the connecting pipe 3 and the joint 2 are fixed together using the fixing member. The sealing ring 5 tightens the connecting pipe 3 and the joint 2, thereby reducing oil or water leakage from the connection between the connecting pipe 3 and the joint 2. If leakage occurs at the connection between the connecting pipe 3 and the joint 2, the dripping prevention assembly collects the dripping oil or water, preventing it from dripping onto the floor and affecting the workshop environment.
[0031] For details, see Figure 3 The fixing member is a fixed tube 6, which is slidably mounted on the connecting tube 3. One end of the fixed tube 6 is open and plugs into the sealing ring 4. The inner wall of the fixed tube 6 is fixedly connected to an internal thread 7, and the outer wall of the connector 2 is fixedly connected to an external thread 8 corresponding to the internal thread 7. Under the action of the external thread 8 and the internal thread 7, the fixed tube 6 and the connector 2 are threadedly connected.
[0032] When it is necessary to connect and fix the connecting pipe 3 and the joint 2, first press the connecting pipe 3 against the joint 2 through the sealing ring 4, then drive the fixing cylinder 6 to move toward the joint 2, and then tighten the fixing cylinder 6 with threads until the sealing ring 4 is completely inserted into the fixing cylinder 6. At this time, the connecting pipe 3 and the joint 2 are sealed and fixedly connected.
[0033] For details, see Figure 1 and Figure 2 The anti-drip component includes a drip shield 9, which is arranged at the connection between the joint 2 and the connecting pipe 3, and the drip shield 9 is transparent.
[0034] In addition, the drip shield 9 further includes an upper cover 10 and a lower cover 11, which are arranged opposite to each other. A clearance groove 12 is respectively opened on the opposite side of the upper cover 10 and the lower cover 11, and the connecting pipe 3 and the joint 2 are respectively plugged into the clearance groove 12.
[0035] See also Figure 2To facilitate the connection and fixation between the upper cover 10 and the lower cover 11, the drip shield 9 is equipped with a connecting assembly comprising bolts 13 and nuts 14. Connecting lugs 15 are fixedly connected to each side of the upper cover 10 and the lower cover 11. The number of bolts 13 and nuts 14 corresponds to the number of connecting lugs 15. The fixed end of the bolt 13 passes through the connecting lug 15 and extends outside the connecting lug 15. The nut 14 is threadedly connected to the fixed end of the bolt 13.
[0036] Drip shield 9 is used to collect oil or water leaking from the connecting pipe 3 and the joint 2. To install drip shield 9, first align the upper cover 10 with the lower cover 11, and then close the upper and lower covers 10 and 11 together. The connecting pipe 3 and the joint 2 are now inserted into the connecting groove. Bolts 13 are then inserted through the connecting lugs 15, and finally, nuts 14 are tightened. The upper and lower covers 10 and 11 are now fixed together, and the drip shield 9 is placed over the connection between the connecting pipe 3 and the joint 2.
[0037] See also Figure 2 A sealing gasket 16 is installed between the upper cover 10 and the lower cover 11. Under the action of the sealing gasket 16, it is beneficial to prevent oil or water from seeping out from between the upper cover 10 and the lower cover 11, thereby improving the sealing between the upper cover 10 and the lower cover 11.
[0038] See also Figure 2 In order to facilitate the directional collection of oil or water in the drip shield 9, the side wall of the lower cover 11 is fixedly connected to an oil drain pipe 17, and the oil drain pipe 17 is fixedly connected to a valve 18.
[0039] When the oil or water in the anti-drip cover 9 needs to be drained, the valve 18 is opened, and the oil or water in the anti-drip cover 9 is then drained from the oil drain pipe 17 .
[0040] It is worth noting that see Figure 3 The side wall fixing ring of the joint 2 is provided with a limiting ring 19, and a limiting groove 20 is opened on the side opposite to the upper cover 10 and the lower cover 11. The limiting ring 19 is plugged into the limiting groove 20, thereby improving the convenience of installation and positioning of the drip-proof cover 9.
[0041] Working principle of an oil-water transport sealing structure:
[0042] When it is necessary to connect and fix the connecting pipe 3 and the joint 2, first press the connecting pipe 3 against the joint 2 through the sealing ring 4, then drive the fixing cylinder 6 to move toward the joint 2, and then tighten the fixing cylinder 6 with threads until the sealing ring 4 is completely inserted into the fixing cylinder 6. At this time, the connecting pipe 3 and the joint 2 are sealed and fixedly connected.
[0043] To prevent leakage at the connecting pipe 3 and joint 2 over time, after the connecting pipe 3 and joint 2 are sealed and securely connected, align the upper cover 10 with the lower cover 11, and then close the upper cover 10 and lower cover 11 together. At this point, the connecting pipe 3 and joint 2 are inserted into the connecting groove. Bolts 13 are then inserted through the connecting ears 15, and finally, nuts 14 are tightened. At this point, the upper cover 10 and lower cover 11 are fixed together, and the drip shield 9 is installed at the connection between the connecting pipe 3 and joint 2.
[0044] In summary, the connecting pipe 3 and the joint 2 are pressed against each other by the sealing ring 5, which helps to reduce the leakage of oil or water from the connection between the connecting pipe 3 and the joint 2. In addition, when the connection between the connecting pipe 3 and the joint 2 leaks, the dripping oil or water is collected by the anti-drip assembly to prevent the oil or water from dripping onto the ground and affecting the workshop environment.
[0045] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
