AI Technical Summary
Technical Problem
Existing two-dimensional solenoid valves are bulky, complex in structure, and difficult to zero, resulting in low stability and low production efficiency.
Method used
The valve body pilot stage and main valve stage are combined into one by adopting a straight groove structure. Combined with a rotary electromagnet assembly, transmission mechanism and reset mechanism, precise zeroing is achieved by using a ball screw pair. The zeroing mechanism is fixed by a magnetic base, simplifying the operation process.
Benefits of technology
It achieves efficient zeroing of two-dimensional valves, improves production efficiency, ensures valve reliability and anti-pollution capability, and is suitable for important industries such as aviation and shipbuilding.

Abstract
This invention discloses a two-dimensional solenoid valve and its zeroing device, relating to the field of solenoid valve technology. The valve body has an installation cavity, within which a valve core is movably disposed. One end of the valve core extends out of the valve body as an input end. The torque output device includes a rotating electromagnet assembly disposed within the valve body. A transmission mechanism is provided between the output end of the rotating electromagnet assembly and the input end of the valve core. A reset mechanism is also provided within the valve body corresponding to the valve core position. The valve core has a straight groove structure, comprising a straight groove and high / low pressure holes. This straight groove structure integrates the pilot stage and the main valve stage into one, solving the problems of bulky and complex conventional valves, as well as the difficulty and low efficiency of zeroing two-dimensional valves.
