Abstract
Without impacting Double-deck cinder discharge valve, relating to the unloading valve structure of metallurgy industry, comprising power plant and two groups of valve groups, often organize valve group and include valve body, valve seat, rotating shaft, rubber seal; One end of two rotating shafts is connected by spring, the other end connecting crank respectively of two rotating shafts, and the other end of each crank connects follower respectively; Power plant connect cam, the profile of cam comprises the opening side arc shaped surface of asymmetric setting and closes side arc shaped surface, the radius of opening side arc shaped surface is diminished to the other end gradually by one end, the radius of closing side arc shaped surface is slowly diminished to the other end gradually by one end, control spring slowly resets, the large end radius of opening side arc shaped surface is equal with the large end radius of closing side arc shaped surface and connect, and the small end radius of opening side arc shaped surface is equal with the small end radius of closedown side arc shaped surface and connect.Valve seat is when closing, and cam contacts completely with follower, and valve seat is closed slowly under spring tension effect, extends the working life of rubber seal.
Description
Technical field
The utility model relates to the unloading valve structure of metallurgy industry.
Background technique
Double-deck cinder discharge valve is made up of upper and lower two unloading valves, operationally upper and lower layer interlocks open and close, pipeline pressure is kept to have very high air locking energy, valve seat adopts special material manufacture, there is heatproof, wear-resisting feature, valve seat is connected with rotating shaft by connecting plate, one end mounting spring of rotating shaft, the other end installs follower, and the output shaft end of speed reducer installs cam, and cam drives the rotation of follower in the process of rotating, thus realize valve seat and open, rely on the pulling force of spring to pull rotating shaft again, valve seat is closed, ash work is unloaded in motion realization and so forth.When valve seat is closed, cam and follower move and there is certain gap, valve seat quick closedown under spring tension effect, now valve seat is very large to rubber seal impact force, work long hours impact, rubber seal is damaged by pressure soon, Double-deck cinder discharge valve cannot seal, unload ash, finally cannot use.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of nothing impact Double-deck cinder discharge valve extending rubber seal working life.
The purpose of this utility model is achieved in that without impacting Double-deck cinder discharge valve, the two groups of valve groups comprising power plant and arrange up and down, often organize valve group and include valve body, valve seat, rotating shaft, each valve body arranges material feeding mouth and discharge port respectively, difference connecting rubber sealing part in the valve body at each material feeding mouth place, each rotating shaft is laterally set on corresponding valve body respectively, respectively by connecting plate connecting valve seat in the rotating shaft in each valve body, one end of two rotating shafts is connected by spring, the other end connecting crank respectively of two rotating shafts, and the other end of each crank connects follower respectively, described power plant connect cam, cam is arranged between two followers, cam and two follower interlacing contact, the profile of described cam comprises the opening side arc shaped surface of asymmetric setting and closes side arc shaped surface, the radius of opening side arc shaped surface is diminished to the other end gradually by one end, the radius of closing side arc shaped surface is slowly diminished to the other end gradually by one end, control spring slowly resets, the large end radius of opening side arc shaped surface is equal with the large end radius of closing side arc shaped surface and connect, the small end radius of opening side arc shaped surface is equal with the small end radius of closing side arc shaped surface and connect.
The utility model is by above design, two surface of contact of cam are asymmetric, valve seat is in the process opened, and cam can contact completely with follower, and valve seat is in the process of closing, cam and follower also can contact completely, diminish before the tension force of spring improves relatively, valve seat is closed slowly under spring tension effect, very little to the impact force of rubber seal, substantially prolongs the working life of rubber seal, the overall performance of unloading valve is more reliable.
