Abstract
The utility model relates to a rotary directional valve which comprises a valve body, a valve plate, a valve rod and a driving device, wherein the valve body is in a triangular, each of the three surfaces of which is provided with a valve hole, the inner side of two of the valve holes is respectively provided with a valve seat, and a seal ring is arranged on the valve seat. The valve rod is rotationally supported in one corner of the valve body; one end of the valve rod hermetically passes through one end of the valve body, and is connected with the driving device; the valve plate is positioned in the valve body, and is corresponding to the valve seat; one side of the valve plate is connected with the valve rod. The utility model has the advantages of fast commutating speed (which can reach one time /1-2 seconds), high temperature resistance (which can reach 300DEG. C), small size, simple structure, superior manufacture manufacturability, long service life, good tightness, strong interchange ability of parts, simple wearing part replacement, low cost, etc.
Description
Technical field
The utility model relates to a kind of rotary reversing valve, is mainly used in the gas reversing mechanism of the oven of metallurgy industry and high-efficiency thermal storage ladle baking facility etc.
Background technique
Mostly commutating device at present commonly used is the bigger welded structure of volume ratio, manufacturing process complexity, working life is short, versatility is poor, change shortcoming such as the difficult and cost height of easily damaged parts.
Summary of the invention
The purpose of this utility model just provides a kind of rotary reversing valve, and the volume ratio that existing commutating device exists is big, manufacturing process is complicated, working life is short, versatility is poor to solve, the replacing problem that easily damaged parts is difficult and cost is high.
The technical solution of the utility model is: comprise valve body, valve plate, valve rod and drive unit.Described valve body is a triangle, respectively is provided with a valve port on its three faces, and the inboard of two valve ports is equipped with valve seat therein, is provided with seal ring on valve seat; Described valve rod rotational support is in an angle of valve body, and the sealing of an end of valve rod passes valve body one end, and is connected with described drive unit; Described valve plate is positioned at valve body and corresponding with described valve seat, and one side of valve plate is connected with described valve rod.
Described drive unit is a cylinder.
Pass between end of valve body and the valve body at described valve rod and to be provided with seal ring.
Seal ring on the described valve seat and the seal ring on the valve rod are made by high-temperature resistant rubber.
The utlity model has commutating speed fast (can reach time/1-2 second), high temperature resistant (can reach 300 ℃), volume is little, simple in structure, anufacturability is good, long service life, good airproof performance, interchangeablity are strong, change the easy and low cost and other advantages of easily damaged parts.
Description of drawings
Fig. 1 is a general structure schematic representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
Referring to Fig. 1 and Fig. 2, the utility model comprises valve body 1, valve plate 2, valve rod 3 and drive unit 4.Described valve body 1 is a triangle, respectively is provided with valve port a, a b, c on its three faces, and the inboard of two valve port a, c is equipped with valve seat therein, is equipped with seal ring 5 on each valve seat.In an angle of valve body 1, an end of valve rod 3 passes valve body one end and is connected with described drive unit described valve rod 3 by bearing 6 rotational support, passes between end of valve body 1 and the valve body at valve rod 3 and is provided with seal ring 7.Described valve plate 2 is positioned at valve body 1 and corresponding with two valve seats, and one side of valve plate 2 is connected with described valve rod 3, makes valve plate 2 can deflection between two valve seats under the drive of valve rod 3.
Described drive unit 4 can adopt cylinder.
The utility model drives valve rod 3 reciprocal deflections by cylinder 4 when work, thereby drives valve plate 2 back and forth deflection between two valve seats, to reach the purpose that makes valve port b and a or b and c alternate conduction on request.Can adopt the to-and-fro motion of programmable controller PLC control cylinder.
