Abstract
The invention belongs to the field of vacuum metallurgical equipment, and in particular relates to an oil cylinder lifting type isolating valve special for a vacuum induction furnace, which is applied between a main chamber and a feeding cabin or temperature measurement cabin of the vacuum induction furnace for isolating or communicating two chamber parts. The isolating valve comprises a valve body (1), wherein a track (3), a valve plate (2), a lifting mechanism (4) and a push and pull mechanism (5) are arranged in the valve body (1); the valve plate (2) is slidably connected with the track (3); one end of the lifting mechanism (4) is fixedly connected with the valve body (1), while the other end is connected with one end of the track (3) through a shaft; the other end of the track (3) is connected with the valve body (1) through the shaft; and one end of the push and pull mechanism (5) is fixedly connected with the valve plate (2), while the other end is connected with the valve body (1) through a shaft. The isolating valve has the characteristics of high sealing property, heat insulation, long service life and the like.
Description
Technical field
The invention 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 valve plate produce motion 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.The such structural requirement machining and the precision of assembling are high, designing and calculating is accurate, motive sealing is unreliable, or high drawback is crossed in quality of materials, the making required precision of gas-flow closure cushion rubber, are unfavorable for the production and the use of equipment.
Summary of the invention
The present invention is intended to overcome the deficiency of existing technology 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 present invention is achieved in that
A kind of oil cylinder lifting type isolating valve special for vacuum induction furnace comprises valve body; In said valve body, be provided with track, valve plate, lifting gear and push-pull mechanism; Said valve plate and slide are joined; Said 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 said track are coupling; Said 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 according to the invention and push-pull mechanism adopt lift cylinder and push cylinder successively respectively.
As another kind of preferred version, track according to the invention joins through hinge and valve body.
Further, valve plate according to the invention can be positioned on the center line of valve body.
Further, valve plate according to the invention can adopt the water cooled seal valve plate.
Water cooled seal valve plate of the present invention is arranged on valve body central authorities, and is set up on the track that an end can hoist through oil cylinder, isolates the position and is communicated with through the push cylinder displacement, with break-make valve body both sides chamber.Advantage of the present invention is to be static seal all, and 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.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.Protection scope of the present invention not only is confined to the statement of following content.
Fig. 1 is an overall structure schematic representation of the present invention;
Fig. 2 is the top plan view of Fig. 1 of the present invention.
Among the figure: 1 is valve body; 2 is valve plate; 3 is track; 4 is lift cylinder; 5 is push cylinder; 6 is the track hinge; 7 is push-pull mechanism hinge I; 8 is push-pull mechanism hinge II.
Embodiment
Referring to Fig. 1 and shown in Figure 2, oil cylinder lifting type isolating valve special for vacuum induction furnace comprises valve body 1; In said valve body 1, be provided with track 3, valve plate 2, lifting gear 4 and push-pull mechanism 5; Said valve plate 2 slides with track 3 and joins; Said lifting gear 4 one ends and valve body 1 are fixedly connected, and its other end and track 3 one ends are coupling; The other end of said track 3 and valve body 1 are coupling; Said push-pull mechanism 5 one ends are coupling with valve plate 2 through push-pull mechanism hinge II 8, and its other end is coupling with valve body 1 through push-pull mechanism hinge I 7.
Referring to shown in Figure 2, be simplified structure, lifting gear 4 according to the invention and push-pull mechanism 5 adopt lift cylinder and push cylinder successively respectively.Track 3 according to the invention joins through hinge 6 and valve body 1.
Set up track 3 in the valve body 1 of the present invention, an end of track 3 is fixed in valve body 1 through hinge 6, and the other end of track 3 can promote through being fixed in the lift cylinder 4 on the valve body 1.
Otherwise, lift cylinder 4 withdrawals, track 3 lifts, push cylinder 5 withdrawals, valve plate 2 moves to the other end of track 3, exposes valve port, accomplishes the connection of separating valve two side cavity.
Be with being appreciated that; More than about specific descriptions of the present invention; Only be used to the present invention is described and be not to be subject to the described technological scheme of the embodiment of the invention; Those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the present invention, to reach identical technique effect; As long as satisfy the use needs, all within protection scope of the present invention.
