Abstract

The utility model provides a modified butterfly valve, relates to valve body technical field, including valve body, valve gap, valve clack, valve shaft, the valve body passes through screw and valve gap fixed connection, have in valve body, the valve gap with the cylindrical cavity of valve shaft complex, the valve shaft passes from this cylindrical cavity, one end is connected with the handle, the other end and valve clack fixed connection, the valve shaft fuses with the valve clack and follows the valve clack diameter and pass the valve clack sets up the supporting shoe with the valve shaft overlap section along perpendicular valve shaft bilateral symmetry. Through fusing valve shaft and valve clack and following the valve clack diameter and pass, when pressure medium is higher in the pipeline, rotate the drive valve clack rotation that the valve shaft can more stabilize. It can cross the deformation of ambassador's valve clack for more effective support valve clack blocks the mobile unlikely pressure of medium to set up supporting shoe with the valve shaft overlap section along perpendicular valve shaft bilateral symmetry at the valve clack.

Description

Improved butterfly valve
Technical field
This utility model is related to valve body technical field and in particular to a kind of butterfly valve.
Background technology
Butterfly valve is flap valve again, it is a kind of simple regulating valve of structure, the butterfly valve that can be used for the on-off control of low pressure pipeline medium refers to that closure member (flap or butterfly plate) is disk, rotate to reach a kind of valve of open and close around valve shaft, valve can be used for controlling the flowing of all kinds fluids such as empty gas and water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.Cut-out and throttling action are acted primarily as on pipeline.Butterfly valve opening and closing element is a discoidal butterfly plate, rotates around the axis of its own in valve body, thus reaching the purpose opening and closing or adjusting.
Butterfly valve on market is typically all to be connected at end points with flap by valve rod, is rotated thus reaching the purpose of the flowing turning off or on pipeline internal medium by the flap that rotarily drives of valve rod.This structure design easily makes flap be deformed when pipeline internal medium pressure is excessive when blocking media flow, because flap need to rotate in pipeline section, can not realize flap by increase flap thickness again and be unlikely to deform problem in high-pressure medium.
Utility model content
Technical problem to be solved in the utility model is to overcome existing technological deficiency, provides a kind of improved butterfly valve.
Technical problem to be solved in the utility model to be realized using following technical scheme:
A kind of improved butterfly valve, including valve body, valve gap, flap, valve shaft, circular groove is arranged on described valve body with valve gap contact surface, built with sealing ring, described valve body is fixedly connected with valve gap groove by screw, has the circular cylindrical cavity with the cooperation of described valve shaft in described valve body, valve gap, valve shaft passes through from this circular cylindrical cavity, one end is connected with handle, and the other end is fixedly connected with flap, and valve shaft is connected with flap and passes through along flap diameter, when pipeline medium pressure is higher, rotate the drive flap rotation that valve shaft can be more firm.
Being symmetrical arranged support block in described flap and valve shaft lap along vertical valve shaft both sides can support flap to block media flow and unlikely pressure crosses the deformation of ambassador's flap for more effective, further described support block is set to hollow structure, when flap does not completely close, the impact to flap for the medium can be reduced, make medium flow through flap along the space in support block.
When needing flap edge to block media flow clockwise or counterclockwise, support block can be respectively provided with flap two sides.
Further, in described valve shaft, packing seal is set with valve gap contact position, prevents valve shaft from causing when rotating poorly sealed and valve gap between.
The beneficial effects of the utility model are: pass through by valve shaft is connected with flap and along flap diameter, when pipeline medium pressure is higher, rotate the drive flap rotation that valve shaft can be more firm.It is symmetrical arranged support block in flap and valve shaft lap along vertical valve shaft both sides and can support that flap blocks media flow and unlikely pressure crosses the deformation of ambassador's flap for more effective.
Brief description
Fig. 1 is this utility model schematic diagram;
Fig. 2 is Fig. 1 along a-a face sectional view.
Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that this utility model is realized are easy to understand, with reference to being specifically illustrating, this utility model is expanded on further.
As Fig. 1, shown in 2, a kind of improved butterfly valve, including valve body 1, valve gap 2, flap 3, valve shaft 4, circular groove is arranged on valve body 1 with valve gap 2 contact surface, groove is built with sealing ring 8, valve body 1 is fixedly connected with valve gap 2 by screw, valve body 1, there is the circular cylindrical cavity with valve shaft 4 cooperation in valve gap 2, valve shaft 4 passes through from this circular cylindrical cavity, one end is connected with handle 6, the other end is fixedly connected with flap 3, valve shaft 4 is connected with flap 3 and passes through along flap 3 diameter, when pipeline medium pressure is higher, rotate valve shaft 4 can be more firm drive flap 3 rotate.
It is symmetrical arranged support block 5 in flap 3 and valve shaft 4 lap along vertical valve rod 4 both sides and can support that flap 3 blocks media flow and unlikely pressure is crossed ambassador's flap 3 and deformed for more effective, further support block 5 is set to hollow structure, when flap does not completely close, the impact to flap for the medium can be reduced, make medium flow through flap 3 along the space in support block 5.
When need flap 3 along block media flow clockwise or counterclockwise when, support block 5 can be respectively provided with flap 3 two sides.
Further, in valve shaft 4, packing seal 7 is set with valve gap 2 contact position, prevents valve shaft 4 from causing when rotating poorly sealed and valve gap 2 between.
Of the present utility model ultimate principle and principal character and of the present utility model advantage have been shown and described above.It should be understood by those skilled in the art that; this utility model is not restricted to the described embodiments; described in above-described embodiment and description, principle of the present utility model is simply described; on the premise of without departing from this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements both fall within the range of claimed this utility model.This utility model claims scope by appending claims and its equivalent thereof.
