Description

Ultra-large electrohydraulic rod valve Technical Field The invention relates to the technical field of valve devices, in particular to an oversized electrohydraulic rod valve which can meet the closing requirement of an oversized stock bin. Background The electrohydraulic rod valve is an industrial valve for controlling the flow of bulk materials such as solid particles, powder and the like, combines electric and hydraulic driving technologies, realizes remote automatic control, and has the working principle that the material granularity is larger than the gap distance and the internal friction between the materials is utilized to separate the materials. The material conveying system is widely applied to industries such as ‌ metallurgy, mines, building materials, electric power, chemical industry, environmental protection ‌ and the like, is particularly suitable for a material conveying system under high-dust, high-temperature or heavy-load working conditions, and is suitable for granular, crystalline or blocky materials. At present, the electro-hydraulic rod valve has small caliber and small bearing force, is driven by manual operation, an air cylinder or an oil cylinder and the like, cannot realize automatic control, cannot meet the closing requirement of an oversized storage bin, and is limited in application scene. Disclosure of Invention The invention aims to provide an oversized electrohydraulic rod inserting valve which is suitable for a heavy-load storage bin, and can be selectively inserted and pulled through an electric pin inserting and pulling device, so that the size of an opening can be manually controlled, and the discharging amount can be adjusted.
