Abstract
The utility model discloses the butterfly valve that a kind of valve shaft and butterfly plate can overall shift out, comprise drive unit, valve gap, valve body, valve seat, butterfly plate seal ring, upper valve shaft, butterfly plate, lower valve shaft and bearing support, the upper axle head of described valve body has the slotted hole that major diameter is greater than butterfly plate external diameter, width is greater than butterfly plate thickness; The lower shaft end of valve body is provided with the through hole for installation shaft bearing, and via bottoms end bracket enclosed, described end cap is also for supporting bearing base.During on-bne repair, remove the drive unit of this butterfly valve, valve gap, end cap and bearing support, upper valve shaft, butterfly plate, lower valve shaft can be shifted out valve body together from slotted hole; Again valve gap is connected the system that pipeline can be made easily to become closed with end cap, makes the System recover at butterfly valve place to working state.
Description
Technical field
The utility model relates to a kind of butterfly valve, specifically a kind of valve shaft and the butterfly plate butterfly valve that can overall shift out.
Background technique
Butterfly valve is Flap valve again, it is the simple modulating valve of a kind of structure, the butterfly valve that can be used for the switch control rule of low pressure pipeline medium refers to that closure member (flap or butterfly plate) is disk, rotate a kind of valve reaching open and close around valve shaft, valve can be used for the flowing controlling all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.On pipeline, main rising is cut off and throttling action.Butterfly valve open-shut device is a discoidal butterfly plate, rotates in valve body around the axis of himself, thus reaches the object opening and closing or regulate.
When existing butterfly valve is installed and need be overhauled on pipeline, butterfly plate can not shift out in valve body.For butterfly plate is shifted out maintenance, butterfly valve must be disassembled from pipeline.Waste time and energy, and pipeline can not be resumed work as early as possible.
Model utility content
The purpose of this utility model is the butterfly valve providing a kind of valve shaft and butterfly plate overall to shift out, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technological scheme:
The butterfly valve that a kind of valve shaft and butterfly plate can overall shift out, comprise drive unit, valve gap, valve body, valve seat, butterfly plate seal ring, upper valve shaft, butterfly plate, lower valve shaft and bearing support, the upper axle head of described valve body has the slotted hole that major diameter is greater than butterfly plate external diameter, width is greater than butterfly plate thickness; The lower shaft end of valve body is provided with the through hole for installation shaft bearing, and via bottoms end bracket enclosed, described end cap is also for supporting bearing base.
As further program of the utility model: the upper axle head of described valve body is provided with flange, and is connected with valve gap by flange.
As the utility model further scheme: the through hole of the lower shaft end of described valve body and bearing support Spielpassung.
Compared with prior art, the beneficial effects of the utility model are:
During on-bne repair, remove the drive unit of this butterfly valve, valve gap, end cap and bearing support, upper valve shaft, butterfly plate, lower valve shaft can be shifted out valve body together from slotted hole; Again valve gap is connected the system that pipeline can be made easily to become closed with end cap, makes the System recover at butterfly valve place to working state.
Accompanying drawing explanation
Fig. 1 is the plan view of the butterfly valve that valve shaft and butterfly plate can overall shift out;
Fig. 2 is the I portion enlarged view in Fig. 1;
Fig. 3 is the side view of the butterfly valve that valve shaft and butterfly plate can overall shift out;
In figure: 1-O shape circle, 2-end cap, 3-bearing support, 4-bearing, 5-lower valve shaft, 6-butterfly plate, the upper valve shaft of 7-, 8-connecting pin, 9-butterfly plate seal ring, 10-valve seat, 11-valve body, 12-valve gap, 13-drive unit.
Embodiment
Be described in more detail below in conjunction with the technological scheme of embodiment to this patent.
Refer to Fig. 1-3, the butterfly valve that a kind of valve shaft and butterfly plate can overall shift out, comprise drive unit 13, valve gap 12, valve body 11, valve seat 10, butterfly plate seal ring 9, upper valve shaft 7, butterfly plate 6, lower valve shaft 5 and bearing support 3, the upper axle head of described valve body 11 has the slotted hole that major diameter is greater than butterfly plate 6 external diameter, width is greater than butterfly plate 6 thickness, and be provided with flange, and be connected with valve gap 12 by flange; The lower shaft end of valve body 11 is provided with for installation shaft bearing 3, and with the through hole of bearing support 3 Spielpassung, via bottoms end cap 2 seals, and described end cap 2 is also for supporting bearing base 3; Opening end cap 2 can make bearing support 3 shift out from through hole easily.
Working principle of the present utility model is:
During work that this butterfly valve is opened (or closedown), drive unit 13 drives upper valve shaft 7 and drives butterfly plate 6 to do center line along upper valve shaft 7 relative to valve body 11 horizontal stroke (or vertical) 90 degree, cross section revolution, connect (or blocking) pipeline, medium is circulated or cut-off.During on-bne repair, remove the drive unit 13 of this butterfly valve, valve gap 12, end cap 2 and bearing support 3, upper valve shaft 7, butterfly plate 6, lower valve shaft 5 can be shifted out valve body 11 together from slotted hole; Again valve gap is connected the system that pipeline can be made easily to become closed with end cap, makes the System recover at butterfly valve place to working state.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned mode of execution, in the ken that one skilled in the relevant art possesses, can also makes a variety of changes under the prerequisite not departing from this patent aim.
Claims (3)
