Abstract
The utility model provides a divided type butterfly valve, comprising a valve body(1) which has a valve seat sealing body(2). The valve seat sealing body(2) is provided with a valve plate(3) which is connected with a valve opening and breaking framework. The utility model is characterized in that the valve body(1) consists of two symmetrical valve bodies which are able to separate along the axial direction of the interval channel of the valve. The two ends of the valve body(1) are provided with tubulatures(4) connected with a culvert whose end has an external border(5). The valve body(1) is provided with an inner border(6) matching with the external border(5) which is at the end of the tubulature(4). The valve(1) is fixed by a fastener. When in repairing, the valve bodies(1) are separated from each other along the axial direction of the interval channel of the valve, and the valve seat sealing body(2), the valve body(3) and the valve making and breaking framework are lifted down to repair, which has the advantages of easy operation, no access of damaging the valve, retrenchment of the flange, and low cost.
Description
One, technical field:
The utility model relates to a kind of butterfly valve that is used for the conveyance fluid medium pipeline, particularly split type butterfly valve.
Two, background technique:
Comparatively close with the utility model is known wafer type butterfly valve, this butterfly valve has valve body, has the valve base sealing body in the valve body, has valve plate in the valve base sealing body, valve plate is connected with valve opening and closing mechanism, the butterfly valve of this structure needs to have in the configuration of valve body two ends the flange of short tube when being connected with pipe, the deficiency of this structure is that valve body is an one, when breaking down maintenance, valve needs valve body is unloaded maintenance from pipeline, at the fragile valve body of maintenance process, and by dress and maintenance operation inconvenience, the overall cost of valve is than higher.
Three, summary of the invention:
Purpose in model utility is to provide a kind of split type butterfly valve, to overcome the deficiency of known technology.
The utility model is achieved in that a kind of split type butterfly valve, it comprises valve body (1), has valve base sealing body (2) in the valve body (1), has valve plate (3) in the valve base sealing body (2), valve plate (3) is connected with valve opening and closing mechanism, its special way is that valve body (1) can form along the symmetrical valve bodies that the axial direction of valve flowing channel separates by two, the two ends of valve body (1) are provided with the short tube (4) that is connected with pipeline, the end of short tube (4) has outer (5), have the interior edge (6) of matching with the outer (5) of short tube (4) end on the valve body (1), valve body (1) is fastenedly connected with fastening piece.
The split type butterfly valve that the utility model provides when maintenance, is separated from each other the axial direction of valve body (1) along valve flowing channel, take off valve base sealing body (2) and valve plate (3) and valve opening and closing mechanism and keep in repair, easy to operate, can not damage valve body, and the saving flange, cost is lower.
Four, description of drawings:
Fig. 1: a kind of structural representation of the utility model:
Five, embodiment:
The utility model is described in further detail in conjunction with embodiment with reference to accompanying drawing.
Embodiment 1, Fig. 1 has provided a kind of concrete structure of the utility model, consult figure (1), a kind of split type butterfly valve, it comprises valve body (1), has valve base sealing body (2) in the valve body (1), has valve plate (3) in the valve base sealing body (2), valve plate (3) is connected with valve opening and closing mechanism, valve body (1) is made up of two symmetrical valve bodies that can separate along the axial direction of valve flowing channel, and the two ends of valve body (1) are provided with the short tube (4) that is connected with pipeline, and the end of short tube (4) has outer (5), have the interior edge (6) of matching with the outer (5) of short tube (4) end on the valve body (1), valve body (1) is fastenedly connected with fastening piece.As being fastenedly connected with bolt and nut.Valve body (1) and short tube (4) can be metalworks, also can be working of plasticss.Valve plate (3) can be a stainless steel part, can be working of plastics.When maintenance, the axial direction of valve body (1) along valve flowing channel is separated from each other, take off valve base sealing body (2) and valve plate (3) and valve opening and closing mechanism and keep in repair, can not damage valve body, easy to operate, and saving flange cost is lower.
Claims (1)
1, a kind of split type butterfly valve, it comprises valve body (1), has valve base sealing body (2) in the valve body (1), has valve plate (3) in the valve base sealing body (2), valve plate (3) is connected with valve opening and closing mechanism, it is characterized in that valve body (1) can form along the symmetrical valve bodies that the axial direction of valve flowing channel separates by two, the two ends of valve body (1) are provided with the short tube (4) that is connected with pipeline, the end of short tube (4) has outer (5), have the interior edge (6) of matching with the outer (5) of short tube (4) end on the valve body (1), valve body (1) is fastenedly connected with fastening piece.
