Novel structure capable of monitoring state of large-stroke hydraulic valve

Abstract

A novel structure capable of monitoring the state of a large-stroke hydraulic valve comprises a valve element, a monitoring assembly and a cover plate body. A cover plate body center hole is formed inside the cover plate body, and the valve element is arranged in the cover plate body center hole in a slidable mode. A piston sleeve installation hole is formed in one side of the cover plate body, and the monitoring assembly is fixedly connected with the interior of the piston sleeve installation hole. The monitoring assembly comprises a piston sleeve, an induction piston, a reset spring, a sensor, a feedback rod, a piston sleeve center hole, a sensor center hole, oil holes, a spherical surface, a center screw hole, a sensor installation hole and a threaded head. The responsiveness, the stability and the reliability of a detection device are improved, the cost is greatly reduced, the accuracy of measurement is guaranteed, the accurate control over the working state of the large-specification hydraulic valve can be possibly achieved, and the control level of a large hydraulic system and the working quality of a main machine facility can be greatly improved.

Description

Technical field: [0001] The invention relates to the technical field of large-stroke hydraulic valve equipment, and more specifically relates to a new structure capable of monitoring the state of a large-stroke hydraulic valve. Background technique: [0002] At present, with the concept of intelligent manufacturing becoming more and more in-depth in various industrial production activities, intelligent control technology is also more and more applied to various industrial equipment. The hydraulic transmission control system is the core part of mechanical equipment. Various hydraulic valves work State detection and control is the foundation of intelligent hydraulic system. However, limited by the effective measurement stroke of high-performance sensors, it is difficult to detect and control large-scale and large-stroke hydraulic valves, which limits the improvement of the control level and work performance of large hydraulic systems.

AI Technical Summary

Problems solved by technology

However, limited by the effective measuring stroke of high-performance sensors, it is very difficult to detect and control large-scale and large-stroke hydraulic valves, which limits the control level and work performance of large hydraulic systems.

[0003] Cartridge valves with ordinary structures, because the movement stroke of the spool is too long, has far exceeded the range of high-precision sensors, and the sensor cannot be used to monitor the movement state of the spool, so the working state of the valve cannot be accurately controlled
