Description
Technical field
The present invention relates to a kind of butterfly valve, and in particular to a kind of double-channel butterfly valve.
Background technology
Butterfly valve is called flap valve, is a kind of regulating valve simple in construction, what the switch available for low pressure pipeline medium controlled
Butterfly valve refers to closure member（Flap or butterfly plate）For disk, a kind of valve of open and close is reached around valve shaft rotation, valve can
For controlling all kinds such as empty gas and water, steam, various Korrosionsmediums, mud, oil product, liquid metal and radiating medium
The flowing of fluid.It is main on pipeline to play cut-out and throttling action.Butterfly valve opening and closing element is a discoidal butterfly plate, in valve body
Rotated around the axis of its own, so as to reach the purpose for opening and closing or adjusting.Existing butterfly valve is generally single channel valve, function list
One, the flow velocity and break-make of liquid can only be controlled, it is impossible to change flow direction, two single-passes are generally required needing to change when liquid flows to
Road valve, very inconvenient and cost are higher.
The content of the invention
In order to overcome deficiency of the prior art, the invention provides a kind of double-channel butterfly valve.
In order to solve the above-mentioned technical problem, the present invention adopts the following technical scheme that：
A kind of double-channel butterfly valve, including valve body, valve rod are equipped with the valve body, the side of the valve rod is fixed with semicircle
The valve plate one of shape, sleeve is arranged with the valve rod, the cross section of the sleeve is 3/4ths annulus, and the sleeve can phase
Rotated for valve rod in 90 degree, semicircular valve plate two is fixed with the sleeve, when sleeve and valve rod turn to 90 from 0 degree
When spending, the angle between valve plate one and valve plate two goes to 180 degree from 90 degree, and the upper end of the valve rod is provided with rotating disk, the sleeve
Upper end be provided with regulation ring, the side of the valve body is provided with two tube channels side by side.
Preferably, being provided with sealing gasket between the sleeve and valve rod, the sealing gasket is fixed on the sleeve.
Preferably, the sealing gasket is made up of rubber.
Preferably, the regulation ring is provided with locking mechanism, it is provided with and institute 0 degree and 90 degree of position on the valve rod
State the neck that locking mechanism is engaged.
Preferably, the inwall of the valve body and the surface of valve plate one and valve plate two are equipped with sealant.
Preferably, the sealant is abrasive rubber.
Preferably, the cavity of the valve inner is spherical.
Preferably, multiple equally distributed necks are additionally provided with the valve rod between 0 degree and 90 degree.
The beneficial effects of the invention are as follows：
The present invention is provided with valve plate one and valve plate two in valve body, because the angle between valve plate one and valve plate two can be 90
Spend between 180 degree and adjust, when valve plate one and valve plate two are in 180 degree angle, unlatching and the pass of two passages can be realized simultaneously
Close, when valve plate one and valve plate two are in an angle of 90 degrees, a passage can be closed and open a passage, change stream so as to reach
To purpose, the present invention it is rational in infrastructure, it is practical, a pipeline can be divided into two branch roads, it is not necessary to add extra
Valve, save cost.

Embodiment
The invention will be further described with reference to the accompanying drawings and detailed description：
As shown in Fig. 1 to Fig. 4, a kind of double-channel butterfly valve, including valve body 1 is equipped with valve rod 2 on valve body 1, and the one of valve rod 2
Side is fixed with semicircular valve plate 1, is arranged with sleeve 3 on valve rod 2, and the cross section of sleeve 3 is 3/4ths annulus, sleeve 3
It can be rotated relative to valve rod 2 in 90 degree, semicircular valve plate 25 is fixed with sleeve 3, when sleeve 3 and valve rod 2 are from 0 degree
When turning to 90 degree, the angle between valve plate 1 and valve plate 25 goes to 180 degree from 90 degree, and the upper end of valve rod 2 is provided with rotating disk 6,
The upper end of sleeve 3 is provided with regulation ring 7, and the side of valve body 1 is provided with two tube channels 8 side by side, and the cavity inside valve body 1 is spherical.
Sealing gasket 9 is provided between sleeve 3 and valve rod 2, sealing gasket 9 is fixed on sleeve 3.Sealing gasket 9 is made up of rubber.
Regulation ring 7 is provided with locking mechanism 10, is provided with 0 degree and 90 degree of position on valve rod 2 and matches with locking mechanism 10
The neck 11 of conjunction.In order to more flexibly adjust flow, multiple uniform points are additionally provided with valve rod 2 between 0 degree and 90 degree
