[0031] Further, the outer circle of the straight pipe 102a-1 is fixedly connected to the connecting position of the straight pipe 102a-1 and the reinforcing ring 102, and the bottom of the straight pipe 102a-1 is in communication with the inner cavity of the reinforcing ring 102.

[0032] Further, the top of the straight pipe 102a-1 is fixedly connected to the bottom of the receiving hopper 102a-2, and the straight pipe 102a-1 is in a communication state with the receiving hopper 102a-2.

[0033] Further, the end, away from the sealing seat 102a-3b, of the vertical rod 102a-3 penetrates the receiving hopper 102a-2 and is in sliding contact with the receiving hopper 102a-2 and is sealed.

[0034] Further, one end of the spring 102a-3a is fixedly connected to the inner wall of the receiving hopper 102a-2, and the other end of the spring 102a-3a is fixedly connected to the surface of the sealing seat 102a-3b.

[0035] Further, the sealing seat 102a-3b is located in the straight pipe 102a-1, and the outer circle of the sealing seat 102a-3b is in sliding contact with the inner wall of the straight pipe 102a-1 and is sealed.

[0036] Further, the number of the flow protection pieces 102a is three, and the three flow protection pieces 102a are distributed on the top of the reinforcing ring 102.

[0037] Further, the number of the vertical rods 102a-3 is three, and the three vertical rods 102a-3 are distributed around the outside of the flow pipe 102a-2a.

[0038] Further, the bottom of the drain pipe 102a-2a is in communication with the inner cavity of the receiving hopper 102a-2, and the inner diameter of the top of the inner cavity of the receiving hopper 102a-2 is greater than the inner diameter of the straight pipe 102a-1.

[0039] It should be noted that the warning control member 101b includes a controller, a buzzer fixedly installed on the controller, and a battery installed inside the controller, wherein the flow sensor 102a-2a1 is electrically connected to the controller, and the detection signal of the flow sensor 102a-2a1 is transmitted to the controller, and the controller can control the working state of the buzzer;

[0040] The inside of the transition pipe 101 and the reinforcing ring 102 are fixedly embedded with PVDF plastic, which has excellent mechanical properties and can achieve internal reinforcement, thereby improving the overall strength of the transition pipe 101 and the reinforcing ring 102;

[0041] By setting the external thread joint 101a, the liquid system pipeline can be conveniently communicated with the outside, thereby meeting the hydraulic oil transmission requirement. By setting the reinforcing ring 102, the installation requirement of the three drain protection members 102a can be met at the same time. By setting the straight pipe 102a-1, the receiving hopper 102a-2 and the reinforcing ring 102 can be communicated, and the displacement space requirement of the sealing seat 102a-3b can be met. By setting the receiving hopper 102a-2, the installation requirement of the drain pipe 102a-2a can be met, and the receiving hopper 102a-2 has a larger transmission space than the sealing seat 102a-3b, so that the oil liquid can be guided to the drain pipe 102a-2a for discharge. By setting the drain pipe 102a-2a, the transmitted oil liquid can be guided and discharged. By setting the flow sensor 102a-2a1, the flow rate of the hydraulic oil flowing through the drain pipe 102a-2a can be monitored in real time. By setting the vertical rod 102a-3, the vertical rod 102a-3 can be installed through the receiving hopper 102a-2, thereby guiding the displacement of the sealing seat 102a-3b. By setting the spring 102a-3a, the sealing seat 102a-3b can be elastically supported, so that the sealing seat 102a-3b can be prevented from being randomly displaced under the action of external force. By setting the sealing seat 102a-3b, the sealing seat 102a-3b can be slidingly and sealingly installed in the straight pipe 102a-1, thereby preventing the hydraulic oil from being randomly transmitted outward.

[0042] In use, each component is in the initial installation state, first cooperate with the outer thread joint 101a and the pipeline in the hydraulic system can be communicated, can make the hydraulic oil normal flow through the outer thread joint 101a, transition pipe 101 and reinforcing ring 102, at the same time, due to the pressure of the hydraulic oil in the hydraulic system, the sealing seat 102a-3b can be displaced outwardly in the straight pipe 102a-1, and because the spring 102a-3a elastically supports the sealing seat 102a-3b, the sealing seat 102a-3b can be maintained in the straight pipe 102a-1 under normal hydraulic system, when the hydraulic system appears unexpected and the transmission pressure of the hydraulic oil is too large, the sealing seat 102a-3b will be further driven to displace outwardly, the spring 102a-3a will be further compressed, until the sealing seat 102a-3b enters the receiving hopper 102a-2, so that the hydraulic oil enters the receiving hopper 102a-2 through the gap between the sealing seat 102a-3b and the receiving hopper 102a-2, and finally is discharged through the drain pipe 102a-2a, completing the safety pressure relief, at this time, the flow sensor 102a-2a1 detects the passage of the hydraulic oil, generates a flow signal, and the signal is transmitted to the controller in the warning control 101b, the buzzer is controlled to work by the controller to warn and remind, in actual use, due to unexpected factors, the hydraulic oil pressure is not the same, and because the three straight pipes 102a-1 are of different lengths, when the sealing seat 102a-3b in the shorter straight pipe 102a-1 is placed in the receiving hopper 102a-2, single-point pressure relief can be completed, the high-pressure hydraulic oil will continue to drive the sealing seat 102a-3b in the medium-length straight pipe 102a-1 to slide, until double-point pressure relief is completed, and similarly, when the internal pressure of the hydraulic oil is higher, the sealing seat 102a-3b in the longer straight pipe 102a-1 is placed in the receiving hopper 102a-2 to complete three-point pressure relief, meeting the needs of various safety pressure relief protection, and the explosion-proof performance is better.

[0043] In summary, by setting the reinforcing ring 102 and the pressure relief protection 102a, when the hydraulic system is unexpectedly high pressure, the hydraulic oil will push the sealing seat 102a-3b to automatically displace outwardly, the spring 102a-3a is compressed, until the sealing seat 102a-3b is placed in the receiving hopper 102a-2, so that the hydraulic oil enters the receiving hopper 102a-2 and is discharged by the drain pipe 102a-2a, and because the straight pipes 102a-1 are of different lengths, different high pressures in the hydraulic system can make the hydraulic oil be shunted and discharged through different positions of the drain pipe 102a-2a, which is more in line with the actual use requirements.
