Abstract
The invention discloses a kettle bottom top bottom valve structure of a graphite reaction kettle. The kettle bottom top bottom valve structure comprises a kettle bottom and a kettle bottom cover plate, wherein a screw rod penetrates through the kettle bottom and the kettle bottom cover plate, one end of the screw rod extends to the inside of the kettle bottom, and in addition, the end part is provided with a valve core; the other end of the screw rod extends to the outer part of the kettle bottom cover plate, in addition, the end part is respectively provided with a holding ring and a flange, and a positioning pin is also arranged on the screw rod; a discharging opening is also formed in the bottle bottom cover plate, and is connected with a discharging passage of the kettle bottom through a pipeline. The kettle bottom top bottom valve structure has the advantages that the structure is simple, the design is reasonable, and the valve core and the holding ring are designed into the graphite structure, so that the discharging opening cannot be easily blocked during the material discharging, the discharging speed is ensured, in addition, the partial graphite structure is adopted, the whole top bottom valve has the anticorrosion effect, and the application range is increased.
Description
Technical field
The present invention relates to a kind of overhead valve and bottom valve structure, be specifically related to a kind of overhead valve and bottom valve structure be applied at the bottom of graphite reactor still.
Background technique
In conventional large-scale graphite reactor equipment, need discharging valve is installed bottom reactor.This discharging valve is generally manually operated valve, and conventional is adopt overhead valve and bottom valve structure, carries out blowing operation by the operation of overhead valve and bottom valve.Existing conventional overhead valve and bottom valve, due to the problem of selecting of structure and material, causes easily blocking discharging pipeline when blowing, thus have impact on discharging speed, reduce working efficiency.
Summary of the invention
Goal of the invention: the object of the invention is to solve deficiency of the prior art, provides a kind of discharging speed, easy to operate of ensureing, overhead valve and bottom valve structure at the bottom of the graphite reactor still that can increase work efficiency.
Technological scheme: overhead valve and bottom valve structure at the bottom of a kind of graphite reactor still of the present invention, comprises at the bottom of still and still bottom plate, and running through at the bottom of described still and in still bottom plate has a screw rod, one end of described screw rod extends at the bottom of described still inner, and is provided with spool in end; The other end of described screw rod extends to described still bottom plate outside, and is respectively equipped with circle holding and flange in end, and described screw rod is also provided with locating stud; Described still bottom plate is also provided with discharge port, and described discharge port is connected to the tapping channel at the bottom of described still by pipeline.
As optimization, described spool and circle holding are graphite structure.
As optimization, between at the bottom of described spool and described still, be provided with fluorine rubber.
As optimization, between described still bottom plate and described circle holding, be provided with polytetrafluoroethylene sealing gasket.
As optimization, between described circle holding and described flange, be provided with O type circle.
Beneficial effect: structure of the present invention is simple, reasonable in design, and by spool and circle holding are designed to graphite structure, thus ensure that discharge port is not easily plugged when discharging, thus ensure that the speed of discharging, and adopt part graphite structure, make whole overhead valve and bottom valve have corrosion-resistant effect, thus add application area.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Overhead valve and bottom valve structure at the bottom of a kind of graphite reactor still as shown in Figure 1, to comprise at the bottom of still 1 and still bottom plate 2, at the bottom of described still 1 and still bottom plate 2 in run through and have a screw rod 3, one end of described screw rod 3 to extend at the bottom of described still 1 inner, and is provided with spool 4 in end; The other end of described screw rod 3 extends to described still bottom plate 2 outside, and is respectively equipped with circle holding 7 and flange 8 in end, and described screw rod 3 is also provided with locating stud 5; Described still bottom plate 2 is also provided with discharge port 6, and described discharge port 6 is connected to the tapping channel of at the bottom of described still 1 by pipeline.
As the further optimization of technique scheme, in order to ensure the sealability between overhead valve and bottom valve and reactor: described spool 4 and circle holding 7 are graphite structure.Fluorine rubber 10 is provided with between 1 at the bottom of described spool 4 and described still.Polytetrafluoroethylene sealing gasket 9 is provided with between described still bottom plate 2 and described circle holding 7.O type circle 11 is provided with between described circle holding 7 and described flange 8.
Structure of the present invention is simple, reasonable in design, and by spool and circle holding are designed to graphite structure, thus ensure that discharge port is not easily plugged when discharging, thus ensure that the speed of discharging, and adopt part graphite structure, make whole overhead valve and bottom valve have corrosion-resistant effect, thus add application area.
