Description
Technical field
The utility model belongs to the vacuum metallurgy apparatus field, relate in particular to a kind of be applied to the vacuum induction furnace main chamber and add feed bin or the thermometric storehouse between, isolate or be communicated with the oil cylinder lifting type isolating valve special for vacuum induction furnace of two-part chamber.
Background technique
The large-scale vacuum induction furnace is the heavy alloyed smelting equipment of present melting, and the development of material industry then requires the purity of molten alloy more and more high, except require impurity content low, also require gas content to lack.
Domestic be applied to the vacuum induction furnace main chamber at present and add feed bin or the thermometric storehouse between the structure type of separating valve mainly be that the cylinder bar of valve body outside cylinder passes the valve plate that the motive sealing push-and-pull places rail slot, connecting rod is arranged on the valve plate, when valve plate move to sealed mouth top collision spacing after, the connecting rod rotation, make the motion of valve plate generation perpendicular to cylinder bar direction, thereby reach the purpose of sealing, perhaps do not have the valve of connecting rod, use modes such as inflating cushion rubber to seal.Such structural requirement machining and precision height, the designing and calculating of assembling is accurate, motive sealing is unreliable, or to the quality of materials of gas-flow closure cushion rubber, make required precision and cross high drawback, be unfavorable for the production and the use of equipment.
The model utility content
The utility model is intended to overcome the deficiencies in the prior art part and provides a kind of simple in structure, and is heat insulation, good seal performance, the oil cylinder lifting type isolating valve special for vacuum induction furnace of long service life.
For achieving the above object, the utility model is achieved in that
A kind of oil cylinder lifting type isolating valve special for vacuum induction furnace comprises valve body; In described valve body, be provided with track, valve plate, lifting gear and push-pull mechanism; Described valve plate and slide are joined; Described lifting gear one end and valve body are fixedly connected, and its other end and track one end are coupling; The other end and the valve body of described track are coupling; Described push-pull mechanism one end and valve plate are coupling, and its other end and valve body are coupling.
As a kind of preferred version, lifting gear described in the utility model and push-pull mechanism adopt lift cylinder and push cylinder successively respectively.
As another kind of preferred version, track described in the utility model joins through hinge and valve body.
Further, valve plate described in the utility model can be positioned on the center line of valve body.
Further, valve plate described in the utility model can adopt the water cooled seal valve plate.
The utility model water cooled seal valve plate is arranged on valve body central authorities, and is set up on the track that an end can hoist by oil cylinder, isolates the position and is communicated with by the push cylinder displacement, with break-make valve body both sides chamber.The utility model has the advantages that to be static seal all, track vertically hoists, thus the chamber good leak tightness, ne-leakage gas phenomenon; After track hoisted, valve plate moved again, does not wipe and bumps seal ring; Valve plate is a water-cooling structure, and is heat insulation fully, stopped thermal radiation and transmission of heat, and this valve also has simple and reliable for structurely, easy to operate, non-maintaining in addition, advantage such as can use for a long time.
