Abstract

The utility model discloses overhead valve and bottom valve structure at the bottom of a kind of graphite reactor still, comprise at the bottom of still and still bottom plate, running through at the bottom of described still and in still bottom plate has a screw rod, and 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.The utility model structure 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.

Description

Overhead valve and bottom valve structure at the bottom of a kind of graphite reactor still
Technical field
The utility model relates to a kind of overhead valve and bottom valve structure, is 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.
Model utility content
Model utility object: the purpose of this utility model 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 described in the utility model, comprise at the bottom of still and still bottom plate, run through at the bottom of described still and in still bottom plate and have 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: the utility model structure 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 utility model.
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.
The utility model structure 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.
