[0002] The multi-way valve is an important component in crude oil extraction equipment. The multi-way valve has multiple oil ports (or called liquid inlets), and the multiple oil ports are all connected to pipelines for transporting oil (including metering pipelines, liquid pipelines and gathering pipelines). The application number CN201810179958.X is retrieved. It is a multi-way valve that controls the on-off of the liquid inlet and the metering port through two valve cores, making the method of measuring the oil flow more flexible; the liquid inlet is controlled by two valve cores, so that the number of single wells connected to the valve body is doubled, and it is more advantageous when used in limited spaces with high pressure and large size requiring multiple wells.

[0003] Similar to the above-mentioned multi-way valve: Although the opening and closing of the liquid port and the metering port are controlled by two valve cores, making the method of measuring oil flow more flexible, firstly, the multi-way valve is often fixedly connected to the drive motor at this stage. When facing a power outage or motor failure, the motor needs to be disassembled, and it requires the use of specific tools to disassemble and replace it. Secondly, when a leak occurs in the pipeline connected to the multi-way valve, it is impossible to quickly determine the specific location of the leaking pipeline.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a multi-way valve with a detection channel leakage structure is proposed to achieve a more practical purpose. Utility Model Content
