[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1As shown, a hydraulic single-acting butterfly valve pipeline includes an oil tank 1. The oil tank 1 is used to store hydraulic oil and is the basic part of the hydraulic system. It provides the source of hydraulic oil. The large-capacity oil tank 1 can ensure the continuous operation of the system, reduce the need for frequent refueling, and maintain the stability of the system. An oil pipeline 2 is led out of the oil tank 1. The oil pipeline 2 is used to transmit hydraulic oil. The pipeline is reasonably designed to withstand high pressure, reduce the risk of oil leakage, and ensure efficient transmission of hydraulic oil.

[0024] The oil pipeline 2 is connected to the oil pump 3, which pressurizes and delivers the hydraulic oil. The efficient oil pump 3 can provide stable pressure to meet different workload requirements. After passing through the oil pump 3, the oil pipeline 2 is connected to the oil tank 8 through the reversing valve 6 and the speed regulating valve 7. The oil tank 8 serves as a temporary storage area or outflow part of the hydraulic oil to ensure that the hydraulic oil flows along the predetermined path, which can reduce the pulsation and pressure fluctuation of the oil and improve the stability of the system. The reversing valve 6 controls the flow direction of the hydraulic oil, and the speed regulating valve 7 controls the flow rate and flow of the hydraulic oil.

[0025] A return pipe 10 is led out from the oil pipeline 2 and connected to a collection tank 12 through a reversing valve 6. The collection tank 12 is used to collect the refluxed hydraulic oil to prevent leakage and oil waste, and can effectively recycle the hydraulic oil, reduce environmental pollution, and improve the reuse rate of the oil. The return pipe 10 returns the excess hydraulic oil to achieve the recycling of the oil, which can reduce the waste of the oil, improve the energy utilization rate, and reduce the operating cost.

[0026] A butterfly valve 11 is provided on the return pipe 10. The butterfly valve 11 is installed on the return pipe 10 to control the return flow of the hydraulic oil and adjust the pressure and flow. The butterfly valve 11 has a simple structure and a fast response speed and can quickly adjust the flow state of the fluid.

[0027] An overflow pipe 13 is led out of the oil pipeline 2 to the collecting tank 12. The overflow pipe 13 is used to guide the excess hydraulic oil into the collecting tank 12 when the pressure in the pipeline is too high. The overflow pipe 13 can prevent overpressure, reduce the occurrence of accidents, and improve safety.

[0028] The following is a detailed description of the design of the above key components:

[0029] The oil pump 3 is connected to a motor 4. The motor 4 drives the oil pump 3 to operate, and the motor 4 provides a stable power output, and can cooperate closely with the oil pump 3 to improve the response speed and operation efficiency.

[0030] An oil filter 5 is provided on the oil pipeline 2 at the front side of the oil pump 3. The oil filter 5 is used to filter impurities in the hydraulic oil. The oil filter 5 can extend the life of the equipment, reduce the failure rate of the equipment, and ensure the long-term stable operation of the hydraulic system.

[0031] A pressure gauge 9 is provided on the oil pipeline 2. The pressure gauge 9 is used to monitor the pressure of the hydraulic oil to ensure that it operates within a safe range. Real-time pressure monitoring can prevent the occurrence of overpressure, protect the safety of the system, and provide important operating data for the operator.

[0032] The overflow pipe 13 is provided with an overflow valve 14. The overflow valve is installed on the overflow pipe 13. When the system pressure exceeds the set value, the overflow valve 14 automatically opens to release the excess pressure. The overflow valve 14 can prevent accidents caused by excessive system pressure, ensure the safe operation of the system, and extend the service life of the equipment.

[0033] The reversing valve 6 is a three-position four-way O-type manual reversing valve. The three-position four-way O-type manual reversing valve is a common hydraulic control element used to control the flow direction of hydraulic oil. It has three main working positions and is connected to four oil ports to achieve various working states of the hydraulic system. It can be manually operated without power or automatic control, providing greater flexibility and operational safety.

[0034] The standard parts used in the utility model can all be purchased from the market, special-shaped parts can be customized according to the description in the specification and the drawings, the specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the prior art, the machinery, parts and equipment all adopt the conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here. The content not described in detail in this specification belongs to the prior art known to professional and technical personnel in this field.
