Description
Technical field
The invention belongs to metallurgical technology field, it relates to a kind of elastic sealed body structure for the outer a refining unit vacuum hopper of vacuum oven.
Background technology
In the outer a refining unit of vacuum oven, vacuum hopper is installed on the top of vacuum chamber feed opening, is connected by tremie pipe. In vacuum process, cone valve sealing realizes and atmospheric isolation, is then added under vacuum conditions in molten steel by the alloying element in feed bin.
At present, the cone valve structure of known vacuum hopper, its elastic sealed body adopts rubber, by the sealing cone of cylinder press seal flange. The cross-sectional shape of elastic sealed body is non-isosceles trapezoid, and the skeletal lines in cross section is straight line, and like this when by the upper and lower surface of Interal fixation elastomerics, owing to contact area is relatively big, pressure is uneven everywhere, may cause leakage on the contrary; Simultaneously owing to trim is inclined-plane, when only overlapping completely with the center of sealing socket, just being sealed reliably, be face contact in theory during the two sealing, same reason also can cause leakage.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, it is an object of the invention to provide a kind of elastic sealed body structure for the outer a refining unit vacuum hopper of vacuum oven, elastic sealed body can be made more effective by the sealing of bolt group retaining plate upper and lower with it, can make extend the work-ing life of the trim of elastic sealed body simultaneously, improve the reliability of sealing, reduce and leak.
In order to realize above-mentioned purpose, the technical solution used in the present invention is:
A kind of elastic sealed body structure for the outer a refining unit vacuum hopper of vacuum oven, upper fixed face 2 and lower fixed face 4 at elastic sealed body arrange boss 1 respectively, arranging boss 27 in the middle part of the inner hole surface 6 of elastic sealed body, the cross-sectional shape of boss 1 and boss 27 is semi arch; In the inside of elastic sealed body, steel plate 5 is set, the skeletal lines of steel plate 5 and the inner hole surface 6 of elastic sealed body, lower fixed face 4 and trim 3 are arranged in parallel respectively, on steel plate 5, the part being parallel to inner hole surface 6 adopts round-corner transition with the junction of the part being parallel to lower fixed face 4, and the part being parallel to lower fixed face 4 adopts circular arc with the junction of the part being parallel to trim 3.
The quantity of described boss 1 is 1～3; The quantity of described boss 27 is 1.
The height of described boss 1 and boss 27 is determined according to the material of elastic sealed body so that it is distortion is within the scope of elasticity distortion, and the thickness of described steel plate 5 is determined according to required elasticity, and the coefficient of elasticity scope of employing is 1.25～2 times of elastic sealed body.
The cross-sectional shape of the trim 3 of described elastic sealed body is circular arc.
Arc transition is all adopted between described boss 1 and upper fixed face 2 and lower fixed face 4.
Vacuum hopper cone valve of the present invention is except the structure of elastic sealed body, and the structure of other parts is known technology, does not describe one by one at this.
Compared with prior art, the present invention adopts the structure of the elastic sealed body of a kind of optimization, utilize the boss arranged in the upper and lower fixed face of resilient seal surface and inner hole surface, reduce contact seal area, ensureing the sealing between elastic sealed body top and bottom and retaining plate, the trim of elastomerics adopts circular arc face simultaneously, and is linear contact lay between sealing socket, the reliability of sealing can be increased, simultaneously can the contact position of easier adjusting and optimizing sealing.
Accompanying drawing explanation
Fig. 1 is elastic sealed body cross-sectional view of the present invention.
Embodiment
Below in conjunction with drawings and Examples, embodiments of the present invention are described in detail.
As shown in Figure 1, a kind of elastic sealed body structure for the outer a refining unit vacuum hopper of vacuum oven, upper fixed face 2 and lower fixed face 4 at elastic sealed body arrange 2 boss 1 respectively, arranging 1 boss 27 in the middle part of the inner hole surface 6 of elastic sealed body, the cross-sectional shape of boss 1 and boss 27 is semi arch. The height of boss 1 and boss 27 should be determined according to the material of elastic sealed body, and after fixed face 2 and lower fixed face 4 are fixed thereon, the distortion of boss 1 and boss 27 should be within the scope of elasticity distortion. Arc transition is all adopted between boss 1 and upper fixed face 2 and lower fixed face 4. Contact area when boss 1 can reduce sealing is set, improves sealing property at the same pressure; The cross-sectional shape of the trim 3 of elastic sealed body is circular arc, it is possible to controlled in the reasonable scope zone of action during sealing, extends sealing effect and the life-span of elastic sealed body.
The inside of elastic sealed body is provided with steel plate 5, the skeletal lines of steel plate 5 and the inner hole surface 6 of elastic sealed body, lower fixed face 4 and trim 3 equidistant parallel layout respectively, on steel plate 5, the part being parallel to inner hole surface 6 adopts round-corner transition with the junction (in Fig. 1 A place) of the part being parallel to lower fixed face 4, and the junction (in Fig. 1 B place) of the part and the part being parallel to trim 3 that are parallel to lower fixed face 4 adopts circular arc. The thickness of steel plate 5 should be determined according to required elasticity, the general coefficient of elasticity scope adopted is 1.25～2 times of elastic sealed body, when elastic sealed body coefficient of elasticity is lower, the coefficient of elasticity of steel plate 5 adopts the numerical value of higher range, namely the thickness of steel plate 5 is bigger, otherwise, the coefficient of elasticity of steel plate 5 adopts the numerical value of lower scope, and namely the thickness of steel plate 5 is less.
Vacuum hopper cone valve of the present invention is except the structure of elastic sealed body, and the structure of other parts is known technology, does not describe one by one at this.
To sum up, the present invention designs the annular small embossment of more than twice or twice at the contact surface up and down that elastic sealed body is connected with retaining plate by bolt group, can ensure that when bolt group is tightened the contact surface sealing of the two is reliable;The trim of elastic sealed body adopts circular arc face in addition, reduces the contact surface between elastic sealed body and stationary seal face, it is to increase stopping property, can ensure the reasonableness of sealing contact surface simultaneously.
