DETAILED DESCRIPTION

[0020] The technical solution in the embodiment of the present application is to solve the problem that the existing one-way valve is not easy to remove from the oil outlet pipe. The overall idea is as follows:

[0021] Embodiment 1:

[0022] See also Figure 1-Figure 4 , an oil pump oil outlet pipe structure with a detachable one-way valve, comprising an oil pump 2, an oil outlet pipe 1, a one-way valve 3 and a one-way valve auxiliary disassembly component 4:

[0023] One side of the oil outlet pipe 1 is connected to the oil outlet of the oil pump 2, and the other side opposite to it is opened with a mounting port 11;

[0024] The one-way valve 3 includes a one-way valve housing 31 located in the inner cavity of the oil outlet pipe 1, and one end of the one-way valve housing 31 abuts against the oil outlet of the oil pump 2;

[0025] The one-way valve auxiliary disassembly member 4 is detachably fixed at the installation opening 11 and pressed against the other end of the one-way valve housing 31 .

[0026] In this embodiment, a mounting port 11 is designed on the other side of the oil outlet pipe 1 , and a one-way valve auxiliary disassembly component 4 is provided, which is convenient for disassembling and assembling the one-way valve 3 .

[0027] The one-way valve housing 31 includes a flange 41 which is sealed at the installation opening 11 and is used to press against the other end of the one-way valve housing 31 . A locking bolt 42 is installed on the flange 41 to detachably fix it to the outer side of the oil outlet pipe 1 .

[0028] During disassembly, the locking bolt 42 is unscrewed to remove the flange 41 blocking the installation opening 11, and the one-way valve 3 can be taken out, thereby improving the convenience of disassembly and assembly.

[0029] An annular groove A411 is formed on the peripheral side of the flange 41 at the installation opening 11, and a sealing rubber ring A43 is provided in the annular groove A411, which is closely attached to the inner wall of the installation opening 11. Specifically, the design of the sealing rubber ring A43 is conducive to increasing the sealing performance of the connection between the flange 41 and the oil outlet pipe 1, and reducing the probability of oil in the oil outlet pipe 1 leaking out from the gap between the two.

[0030] An annular groove B311 is provided on the outer wall of the one side of the one-way valve housing 31 close to the oil pump 2, and a sealing rubber ring B32 is provided in the annular groove B311, which is close to the connecting port between the oil outlet pipe 1 and the oil pump 2. Specifically, the design of the sealing rubber ring B32 is conducive to increasing the sealing performance of the connection between the one-way valve housing 31 and the oil outlet pipe 1, and reducing the probability of the oil in the oil pump 2 leaking from the gap between the one-way valve 3 and the oil outlet pipe 1 to the inside of the oil outlet pipe 1 when the one-way valve 3 is closed.

[0031] An annular groove C12 is provided on one side of the oil outlet pipe 1 that is in contact with the oil pump 2, and a sealing rubber ring C13 is provided in the annular groove C12 that is in contact with the oil outlet pipe 1. Specifically, the design of the sealing rubber ring C13 is conducive to increasing the sealing performance of the joint between the oil pump 2 and the oil outlet pipe 1, and reducing the probability of the oil in the oil pump 2 leaking out from the gap between the oil outlet pipe 1 and the oil pump 2.

[0032] When using this application:

[0033] An installation opening 11 is designed on the other side of the oil outlet pipe 1, and a one-way valve auxiliary disassembly part 4 is provided. During disassembly, the flange 41 blocking the installation opening 11 is removed by unscrewing the locking bolt 42, and the one-way valve 3 can be taken out, thereby improving the convenience of disassembly and assembly.

[0034] At the same time from Figure 1 It can be seen that both ends of the one-way valve housing 31 are respectively supported by the flange 41 and the oil discharge port of the oil pump 2, and the stability is good.

[0035] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present application, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present application.
