Abstract
The utility model discloses a big diameter flat panel valve, which comprises a valve cavity, a flat panel valve core and a valve core linkage device, wherein the valve cavity is formed by a feed opening, and the flat panel valve core is matched with the valve cavity. The big diameter flat panel valve overcomes the problem that a stirring dead angle exists when a traditional valve is combined with a container, and has the characteristics of big diameter of valve core, excellent air tightness and simple structure, and does not have a stirring dead angle when combining with the container.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of large caliber flat plate valve.
Background technique
At present, the tankage of interior agitating device, its feed opening generally is set directly at container bottom, and the tightness during simultaneously for assurance work all can be provided with a control valve on the feed opening.At this, at present the traditional control valve that uses has two kinds on ball valve and dish valve, but because of both structural limitations, with container combination the time, all can produce certain stirring dead angle at container bottom, the material that promptly is arranged in the dead angle can not be stirred device at work and stir, and this result has had a strong impact on the end product quality of mixing quality and material.
As shown in Figure 1, for ball valve 1 ' with container 2 ' combine schematic representation, because of ball valve core 11 ' the surface be a spherical cap structure, make stirring apparatus 21 ' can't go deep into fully ball valve import 12 ' position and produce at this place and to stir the dead angle.
As shown in Figure 2, the schematic representation that combines for dish valve 1 " with container 2 ", because of dish valve core 11 " need when opening to rotate 90 ° around the center; simultaneously the one side will on turn over; this action feature makes the movement clearance 12 of dish valve core 11 " side must be reserved and be not less than spool 11 " radius thereon ", and this gap can not have thing to stop, promptly stirring apparatus 21 " can't enter and form and stir the dead angle.
The model utility content
At the problems referred to above, the utility model provides a kind of large caliber flat plate valve, it has, and the spool bore is big, tightness good, simple in structure, do not have the characteristics that stir the dead angle with container combination.
For achieving the above object, the utility model is by the following technical solutions:
A kind of large caliber flat plate valve is characterized in that: comprise valve pocket, the dull and stereotyped spool that cooperates with valve pocket and a spool linkage that is formed by feed opening.
Above-mentioned valve pocket is provided with the annular flange flange of internal diameter less than the valve pocket internal diameter at the import position.
Above-mentioned dull and stereotyped spool is provided with near the lower end surface of annular flange flange, and one of spool is free end, and the other end is docked by screw with the internal chamber wall of valve pocket.
Above-mentioned spool linkage is arranged on the connection side of spool, and it comprises a line shaft, driving gear and an arc-shaped rack, and wherein the downside of arc-shaped rack one end and spool is hinged, and the other end is realized being connected with line shaft by driving gear.
The joint of above-mentioned annular flange flange lower end surface and spool is provided with seal washer.
Above-mentioned line shaft connects manual handwheel, starting drive or motor.
In use, the rotation of line shaft rotates arc-shaped rack by driving gear, and then the hinged dull and stereotyped spool of drive and arc-shaped rack rotates around its tie point, finishes the unlatching of valve.The valve closing motion action just in contrast.
At this, following the stirring as process of above dull and stereotyped spool determined spool top need not reserve movement clearance, dull and stereotyped spool upper surface can flush setting with container bottom, and it is few as far as possible that the span of stirring apparatus and dull and stereotyped spool upper surface can be provided with, and can not cause stirring the appearance at dead angle.
Dull and stereotyped spool of the present utility model is located by arc-shaped rack, and its motion also drives by arc-shaped rack, and valve core movement is steady.Be provided with seal washer in the joint of annular flange flange lower end surface and spool in addition, can guarantee the tightness of heavy caliber spool well.
Line shaft of the present utility model connects manual handwheel, in use by manually-operable.Line shaft also can be realized operation automatically directly by Pneumatic actuator or driven by motor simultaneously.

Embodiment
Shown in Fig. 3 and 4, a kind of large caliber flat plate valve comprises valve pocket 11, the dull and stereotyped spool 12 that cooperates with valve pocket and a spool linkage 3 that is formed by feed opening.
Described valve pocket 11 is provided with annular flange flange 111 at the import position, and the internal diameter at annular flange flange 111 positions is less than valve pocket 11 internal diameters.
Described spool 12 is provided with near the lower end surface of annular flange flange 111, and one of spool 12 is free end, and dock with screw with the internal chamber wall of valve pocket 11 other end.For strengthening the tightness of spool 12, be provided with seal washer 4 in the joint of annular flange flange 111 lower end surfaces and spool 12 simultaneously, its structure as shown in Figure 4.
Described spool linkage 3 is arranged on the connection side of spool 12, it comprises a line shaft 31, driving gear 32 and an arc-shaped rack 33, wherein the downside center of arc-shaped rack 33 1 ends and spool 12 is hinged, and the other end is by being connected with line shaft 32 with the engagement realization of driving gear 32.
In use, by the rotation of line shaft 31 and the engagement driving of driving gear 32, realize the rotation of arc-shaped rack 33, and then the hinged dull and stereotyped spool 12 of drive and arc-shaped rack 33 is around its screw docking point rotation, finish the operation of feed opening valve opening, its structure such as Fig. 5 show.The closing operation process just in contrast to this.
At this, following the stirring as process of above dull and stereotyped spool 12 determined spool 12 tops need not reserve movement clearance, dull and stereotyped spool 12 upper surfaces can flush setting with container 5 bottoms, it is few as far as possible that the span of stirring apparatus 51 and dull and stereotyped spool 12 upper surfaces can be provided with, and can not cause stirring the appearance at dead angle.
In addition, dull and stereotyped spool 12 of the present utility model is by arc-shaped rack 33 location, and its motion also drives by arc-shaped rack 33, and spool 12 motions steadily.And be arranged on the seal washer 4 of annular flange flange 111 lower end surfaces and spool 12 joints, can guarantee the tightness of heavy caliber spool 12 well.
In sum, the utility model provides a kind of novel vacuum desiccator charging aperture control valve, it has, and the spool bore is big, air-tightness good, simple in structure, do not have the characteristics that stir the dead angle with container combination.
