Abstract

The invention belongs to the technical field of valve bodies, and relates to a three-position four-way water pressure proportional valve based on a high-speed switch valve. The three-position four-waywater pressure proportional valve comprises a valve block, four main valve core assemblies are installed on the valve block, the upper end of each main valve core assembly is provided with a pilot valve assembly in a matched mode, the upper end of each pilot valve assembly is provided with an electromagnet assembly in a matched mode, each main valve core assembly comprises a main valve core arranged in an inner hole of the valve block in a sliding sealing mode, the lower portion of an inner cavity of each main valve core is provided with a damper, main valve core pretightening springs are arranged above the dampers, and main valve core seat pads are arranged between the bottom faces of the main valve cores and the inner hole of the valve block to from soft seal. The proportional valve caneffectively meet operation environment requirements, and the valve core response speed is high.

Description

technical field [0001] The invention belongs to the technical field of valve bodies, and relates to a three-position four-way water pressure proportional valve based on a high-speed switching valve. Background technique [0002] Water-hydraulic transmission technology has attracted widespread attention due to its safety, environmental protection and many other advantages. With the continuous improvement of the categories and specifications of water hydraulic components, their application range is also expanding. [0003] As the core component of hydraulic transmission, the proportional valve works by using electromechanical conversion mechanisms such as proportional electromagnets and stepping motors to drive the movement of the spool, so that the displacement of the spool changes proportionally, thereby controlling the flow rate through the valve port to change proportionally. higher control requirements. [0004] The spool structure of traditional proportional valves is ...
