Abstract
The utility model provides a high-security heat-accumulating reversing device for a heating furnace. The high-security heat-accumulating reversing device for the heating furnace comprises a valve body, an upper right valve plate, a lower right valve plate, a right valve rod, a left valve rod, an upper left valve rod, a lower left valve rod, a left reversing cylinder and a right reversing cylinder. A valve cavity of the valve body is composed of an upper cavity, a lower cavity, a center right cavity and a center left cavity. The upper right valve plate and the lower right valve plate are arranged in the center right cavity which is fixedly connected with the right valve rod. The upper left valve plate and the lower left valve plate are arranged in the center left cavity which is fixedly connected with the left valve rod. The left reversing cylinder and the right reversing cylinder are respectively connected with the left valve rod and the right valve rod in a separate mode. Grooves are formed in the bottom face of the left valve rod and the right valve rod, wherein a card slot end cover is embedded in the grooves, and the card slot end cover is connected with the valve plates through a fastener. According to mutual noninterference between the left valve rod and the right valve rod, the high-security heat-accumulating reversing device for the heating furnace has the advantages that reliability is high, the phenomena of loosing and falling off of the valve plates are effectively avoided, and the safety performance is high.
Description
Technical field
The utility model relates to a kind of valve, particularly relates to the high-performance selector valve that uses in a kind of heat-accumulating industrial furnace kiln.
Background technique
At present, be connected by lever between the high-performance selector valve that uses in the heat-accumulating industrial furnace kiln, left valve rod and right valve rod, realize synchronous drive, the lever stuck phenomenon easily appears in this structure; Valve rod and valve plate are threaded connection rear common employing nut screwing clamping and prevent that valve plate is loosening because turn around time is fast, operating frequency is high, often easily just cause nut loosening after valve plate come off, reliability is low, poor safety performance.
The model utility content
In order to overcome the above-mentioned shortcoming of existing recuperative heater reversing arrangement, the utility model provides a kind of high security recuperative heater reversing arrangement, and its left valve rod and right valve rod are controlled respectively by left and right oil cylinder, mutual noninterference, and reliability is high; And section has groove at the bottom of the left and right valve rod, is inlaid with the draw-in groove end cap in the groove, the draw-in groove end cap is fixed on the valve plate again, has effectively avoided the loosening obscission that reaches of valve plate, and Safety performance is high.
The technological scheme that its technical problem that solves the utility model adopts is a kind of high security recuperative heater reversing arrangement, comprise valve body, upper right valve plate, the bottom right valve plate, right valve rod, left valve rod, upper left valve rod, the lower-left valve rod, left commutation oil cylinder, right commutation oil cylinder, the valve pocket of valve body is divided into epicoele, cavity of resorption, right chamber, left chamber, upper right valve plate and bottom right valve plate are set in the right chamber, and be fixedly connected with right valve rod, upper left valve plate and lower-left valve plate are set in the left chamber, and be fixedly connected with left valve rod, described left commutation oil cylinder be connected the commutation oil cylinder respectively with left valve rod be connected valve rod and be connected separately, described left valve rod and right valve rod bottom end have groove, inlay the draw-in groove end cap in the groove, the draw-in groove end cap is connected with valve plate by fastening piece.
The beneficial effects of the utility model are as follows:
1, left commutation oil cylinder be connected the commutation oil cylinder respectively with left valve rod be connected valve rod and be connected separately, but the independent control of valve rod, mutual noninterference, safe;
2, valve rod and right valve rod bottom end have groove, inlay the draw-in groove end cap in the groove, and the draw-in groove end cap is connected with valve body by fastening piece, guarantee that valve plate can not come off in long-term movement process, and reliability is high, and Security is good.
