Description
Technical field
The present invention relates to butterfly valve, more particularly to a kind of center line stretches butterfly valve.
Background technology
The last century 30's, American invention butterfly valve, when fifties, are passed to Japan, are just generally adopted in Japan to the sixties
With, and promote the thing after being then the seventies in China.Butterfly valve is mainly characterized by：Operational torque is small, installation space it is small and
It is light-weight.By taking DN1000 as an example, butterfly valve about 2T, and gate valve about 3.5T, and butterfly valve has good easily with various combination of drive means
Durability and reliability.Rubber seal butterfly valve shortcoming is throttled in use, can produce cavitation erosion due to the use of improper, makes rubber base
Situations such as peeling off, damaging, then will be according to working condition requirement so how correctly to select.Pass between the aperture and flow of butterfly valve
System, substantially linear ratio change.If for controlling flow, the flow resistance of its discharge characteristic and pipe arrangement also has substantial connection,
Such as two Pipe installing valve apertures, forms are exactly the same, and trunking loss coefficient is different, and the flow difference of valve also can be very
Greatly.If valve is in the larger state of throttling amplitude, the back side of valve plate is easily cavitated, and has the possibility of damage valve, generally
Used outside 15 °.When butterfly valve is in middle aperture, the opening shape that valve body and butterfly plate front end are formed centered on valve shaft,
Both sides, which are formed, completes different states, and the butterfly plate front end of side is moved along current direction, opposite side counter-flow water direction
And move, therefore, side valve body is formed like nozzle shape opening, the similar throttling bore openings of opposite side with valve plate, and nozzle side is than throttling
Effluent speed is much faster, and negative pressure can be produced below the side valve door that throttles, and often occurs that rubber seal comes off.Butterfly valve operating force
Square, because its different value of aperture and valve opening and closing direction is different, horizontal butterfly valve, is particularly large diameter valve, due to the depth of water, on valve shaft,
Torque caused by lower head difference also can not be ignored.In addition, during the device elbow of valve inlet side, bias current is formed, torque has increasing
Add.When valve is in middle aperture, since water flowing torque works, operating mechanism needs self-locking.
In the prior art, butterfly valve is set as just switch, but the butterfly valve often ignored of people also has connect at the same time
The function of part exists.In different environments, for butterfly valve body length to need be different, this just needs to produce many differences
The butterfly valve of specification, this mode is very inflexible and efficiency is low, how to set a kind of connection that can adjust pipe portion passage length
Formula butterfly valve, is the direction that we need to study.
The content of the invention
The present invention proposes that a kind of center line stretches butterfly valve, solves the problems of the prior art.
The technical proposal of the invention is realized in this way：
Center line stretches butterfly valve, including valve body, and the central axial valve body is middle siphunculus, and middle siphunculus inner wall is equipped with valve seat, institute
State middle part section in valve seat and be equipped with butterfly plate, valve shaft is equipped with the middle part of butterfly plate, the valve shaft drives butterfly plate axis to stir and completes opening for butterfly valve
Open and close, the middle siphunculus port grafting flange, adjusts between the flange and valve body especially by bolt adjustment part.
As the preferred solution of the present invention, the valve shaft side elevation and the diameter place in middle siphunculus side cross-sectional are straight
Line coincides.
As the preferred solution of the present invention, body wall is fixed in the valve body shaft lower end, outside valve body upper portion side wall
Equipped with valve neck, the valve shaft upper end is pierced by valve neck, and is plugged in a turbine box.
As the preferred solution of the present invention, the turbine box is secured by bolts at the top surface of the valve neck.
As the preferred solution of the present invention, one handwheel of turbine box external connection, user rotates handwheel, passes through turbine
Turbine and worm is driven in case, and handwheel twisting is converted into rotation of the valve shaft along valve shaft shaft core.
As the preferred solution of the present invention, the flange includes the flange arrangement of eaves outside pipe portion and pipe portion one end, the pipe
Portion is plugged in valve base inner wall.
As the preferred solution of the present invention, the pipe portion outer wall is equipped with a circle annular table, and the annular table is fastened on valve body
At port, the annular table is fastened with valve body by gland and fixing bolt.
As the preferred solution of the present invention, the gland engages contact position top with valve body port arranged on annular table, described
Preferred solution of the inner ring oiling sealing ring as the present invention.
As the preferred solution of the present invention, studs is plugged between the valve body port and flange arrangement.
As the preferred solution of the present invention, the relative inner face between the valve body port and flange arrangement is all equipped with one
Adjusting nut, the adjusting nut are fixed on the studs.
Beneficial effect
The present invention proposes a kind of center line and stretches butterfly valve, including valve body, and it is middle siphunculus that the valve body is central axial, middle siphunculus
Inner wall is equipped with valve seat, and middle part section is equipped with butterfly plate in the valve seat, and valve shaft is equipped with the middle part of butterfly plate, and the valve shaft drives butterfly plate axis to turn over
The dynamic unlatching for completing butterfly valve and closure, the middle siphunculus port grafting flange, especially by bolt between the flange and valve body
Adjustment part adjusts.Light-weight the present invention relates to flexible, flexible butterfly valve seal position can adjust replacement, and sealing performance more may be used
Lean on, it is easy for assemble or unload.
