Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electro-hydraulic sector gates, and specifically relates to a double-push-rod sector gate. Background Art
[0002] In many industries such as industrial production, metallurgy, and coal mine power generation, sector gates are used to achieve the opening and closing of the bin discharging. It is mainly used to control the bin discharging by realizing the opening and closing of the discharging port of the bin in the production process. By operating the control power supply, the forward and reverse rotation of the electro-hydraulic push-rod motor is realized to make the electro-hydraulic push-rod extend and retract, so as to control the opening and closing of the sector gate. The existing sector gate uses an electro-hydraulic push-rod to drive the sector valve plate to realize the opening and closing action. Since the electro-hydraulic push-rod drives in the middle of the valve plate, when the valve plate encounters foreign objects stuck on both sides, the valve plate is prone to lateral deviation and the two sides of the valve plate are out of sync. The unstable driving will jam the valve plate, resulting in equipment failures. The single electro-hydraulic push-rod driving the sector gate has a small driving force, and it is difficult to drive the gate when encountering material caking and jamming, etc. These problems cause the bin to be unable to discharge materials, affect the production of the next process, cause the shutdown of the previous process, and even cause material caking due to long-term non-discharging, etc., affecting the stable operation of the production.
