Two-section type angle valve

The utility model relates to a two-section type angle valve used in pressure balancing work of a vacuum cabin. The two-section type angle valve comprises a valve body and a drive cylinder. The valve body is provided with a first pipeline and a second pipeline which are communicated. The drive cylinder is connected to the valve body. The drive cylinder is provided with a drive shaft moving in the axial direction. An airtight valve block located between the first pipeline and the second pipeline is arranged at the end of the drive shaft and is in movable airtight with the first pipeline. The two-section type angle valve has the advantages that the drive shaft can drive the airtight valve block to generate a first distance with the first pipeline, then the first pipeline and the second pipeline are controlled reduce the pressure difference with the small flow, and a second distance larger than the first distance is generated to finish pressure balance with the large flow. The problem that an object to be machined in the vacuum cabin is blown away due to airflow generated by the pressure difference of the first pipeline and the second pipeline is actually avoided.
