Embodiment
Come to be further elaborated the technical solution of the utility model below in conjunction with the accompanying drawings.
Referring to shown in Fig. 1-2, a kind of above-mentioned butterfly valve, including valve seat 1 in annular, rotated around Pivot Point Center line direction
The rotating shaft that is arranged in the valve seat 1, butterfly plate 4 in the rotating shaft is fixedly arranged on, the butterfly plate 4 is located in the valve seat 1, the butterfly plate 4 and the valve
Being provided between seat 1 is used for sealed O-ring seal 7, and what the O-ring seal 7 was fixed is attached on the inwall of the valve seat 1.Should
Rotating shaft is valve rod.
When butterfly valve is closed, pass through the seamless seal of O-ring seal 7 between the butterfly plate 4 and the valve seat 1；
When butterfly valve is in open mode, the butterfly plate 4 turns over certain angle, face and the sealing ring institute where the butterfly plate 4
Face between formed and allow the opening that passes through of medium.
One end of the rotating shaft passes the formation outrigger shaft of valve seat 1, the butterfly valve also include on the outrigger shaft with the extension
The handwheel 5 that axle is coaxially distributed, the cylinder drive mechanism 6 on the outrigger shaft.The cylinder drive mechanism 6 is located at handwheel 5 and valve
Seat 1 between, the cylinder drive mechanism 6 be used for drive outrigger shaft around Pivot Point Center line direction rotate, so as to drive butterfly plate 4 to rotate
To be opened and closed butterfly valve.
The handwheel 5 is arranged on the end of outrigger shaft, and is coaxially distributed with outrigger shaft, is set by this, can be in cylinder
In the case that drive mechanism 6 breaks down, the opening and closing operations to butterfly valve are quickly realized by handwheel 5.Due to handwheel 5 and extension
Axle is coaxially distributed, and its is simple in construction, operates also more convenient laborsaving.
The cylinder drive mechanism 6 includes cylinder body 61, is located at pushing away in the cylinder body 61 along what its length bearing of trend stretched
The connector 63 being sheathed on the outrigger shaft that bar 62, one end are fixed, the other end of the connector 63 is hinged on the push rod 62.
In the present embodiment, the connector 63 is L-shaped, and the other end of the connector 63 is arranged on push rod 62 by wye piece 8.This is pushed away
Bar 62 and the connector 63 are respectively positioned in the same plane of the vertical outrigger shaft.When push rod 62 stretches out, drive connection part 63 is upward
Rotate；When push rod 62 is retracted, drive connection part 63 is rotated down, and connector 63 drives outrigger shaft synchronous axial system again.
In the present embodiment, the rotating shaft include around Pivot Point Center line direction rotate the short axle 2 being arranged in valve seat 1, around
The major axis 3 being arranged in valve seat 1 that Pivot Point Center line direction is rotated, one end of the major axis 3 passes valve seat 1 and forms the outrigger shaft,
