Body implication.
Embodiment 1
As shown in figure 1, the invention provides a kind of pipeline valve, the valve include rotating shaft 1, valve plate 2, drive mechanism and
With being closed the valve body 4 that pipeline is connected, rotating shaft 1 is rotated with valve body 4 and is connected, and rotating shaft 1 is provided with the pressure radially extended
There is angle or depression bar 1-1 axle of the axis perpendicular to rotating shaft 1 between bar 1-1, i.e. depression bar 1-1 axis and the axis of rotating shaft 1
Line, depression bar 1-1 is rotated with the middle part of valve plate 2 and is connected, and drive mechanism is rotated for drive shaft 1, so that valve plate 2 can be opened and closed in quilt
The opening of closed duct.
Thus, when need close be closed the opening of pipeline when, start drive mechanism, make drive mechanism drive rotating shaft 1 to
Rotated provided with the direction for being closed pipeline, and then valve plate 2 is moved under depression bar 1-1 drives towards the opening for being closed pipeline.If
To be fixedly connected between depression bar 1-1 and valve plate 2, with respect to depression bar 1-1 angle slight change can occur for valve plate 2 after long-term use,
And then cause valve plate 2 close when, be closed pipeline opening a part covered tightly, another part is still unlimited.If depression bar
To rotate connection between 1-1 and valve plate 2, after the top of valve plate 2 or bottom are first contacted with being closed the opening of pipeline, in valve plate
During 2 progressively close off the opening for being closed pipeline, valve plate 2 can adjust itself by relative depression bar 1-1 fine rotation
Direction, makes valve plate 2 be narrowly focused towards being closed the opening of pipeline, is not closed completely and causes the phenomenon leaked out so as to avoid valve plate 2
Occur, and the pressure distribution after closing between valve plate 2 and the opening for being closed pipeline is uniform.
Wherein, valve plate 2 includes sealing plate 2-1 and seal 2-2, and sealing plate 2-1 directions are closed the one of the opening of pipeline
Side is provided with groove, and a seal 2-2 part is embedded in groove, another part can be plugged in the opening for being closed pipeline.
When the lid of valve plate 2 is located in the opening for be closed pipeline, the seal 2-2 being not embedded into groove is plugged in just is closed pipe
In the opening in road, so that avoid causes dust when the opening or sealing plate 2-1 out-of-flatnesses that are closed pipeline produce gap
Leakage.
Preferably, the width of the cross section of groove is gradually reduced from inside to outside, ensure that seal 2-2 and sealing plate 2-
1 close connection, prevents seal 2-2 from being come off from sealing plate 2-1, while can also avoid dust from seal 2-2 and sealing plate
Revealed between 2-1.
Preferably, sealing plate 2-1 area is more than the area for the opening for being closed pipeline.So set and be advantageous in that,
On the one hand, the not fully closed openings for being closed pipeline of sealing plate 2-1 can further be avoided；On the other hand, it is easy in sealing plate
Groove is opened up on 2-1.
Further, depression bar 1-1 is located at the side that valve plate 2 is dorsad closed the opening of pipeline.Thus, depression bar 1-1 is in band
During dynamic valve plate 2 is moved towards the opening for being closed pipeline, rotational angle of the valve plate 2 with respect to depression bar 1-1 can be limited, is carried
High valve plate 2 closes the accuracy and speed for the opening for being closed pipeline；On the other hand, depression bar 1-1 can also form upward to valve plate 2
Support, reduce the stress of valve plate 2 and depression bar 1-1 junctions.
In addition, also including two bearings, the two ends of rotating shaft 1 are rotated by two bearings with valve body 4 respectively to be connected, with
Reduce the friction between rotating shaft 1 and valve body 4, improve the service life of valve.
Preferably, drive mechanism is located at the outside of valve body 4.So set and be advantageous in that, on the one hand, can avoid
When valve plate 2 is opened, easily deposition dust, and then cause drive mechanism to be worn and torn when running in drive mechanism；On the other hand, it is to avoid drive
Motivation structure occupies the volume for being closed pipeline, so as to reduce the flow resistance being closed in pipeline.
Further, drive mechanism includes connecting rod 3-2 and cylinder 3-1, and cylinder 3-1 is rotatably connected on the outer of valve body 4
Side, connecting rod 3-2 one end is connected with cylinder 3-1 piston rod rotation, the other end is fixedly connected with rotating shaft 1.When piston rod is relative
When cylinder 3-1 is moved up and down, drivening rod 3-2 is rotated, and then connecting rod 3-2 drives cylinder 3-1 unitary rotations again, in connecting rod 3-2
Rotated with cylinder 3-1 collective effect lower rotary shaft 1 according to specified angle.
Embodiment 2
With reference to shown in Fig. 2 to Fig. 4, present invention also offers a kind of cleaning shaft, the pipeline includes upper pipe, lower tube
Road, the first connecting tube 5 and above-mentioned pipeline valve, upper pipe be located at lower pipeline top, the top of the first connecting tube 5 with
The open communication of upper pipe, the top of valve body 4 is connected by the first connecting tube 5 with upper pipe, bottom and lower tube
Road is connected, and the opening of the bottom of the first connecting tube 5 is set obliquely downward, and valve plate 2 can be opened and closed in the bottom of the first connecting tube 5.
The structure of pipeline valve in the present embodiment is same as Example 1 with principle, and the present embodiment is repeated no more.
Because the opening of the bottom of the first connecting tube 5 is set obliquely downward, therefore valve plate 2 is in the process gradually closed
In, the top of valve plate 2 is first contacted with the opening of the first connecting tube 5, and the opening of the bottom of valve plate 2 finally with the first connecting tube 5 connects
Touch.Therefore in the closing course of valve plate 2, be gradually deposited in dust on valve plate 2 under gravity along the surface of valve plate 2 from
The bottom of valve plate 2 is fallen, and so as to avoid dust from being stuck between the opening of the connecting tube 5 of valve plate 2 and first, valve plate 2 is closed not
Sternly.In addition, in the opening process of valve plate 2, the bottom of valve plate 2 is first separated with the opening of the first connecting tube 5, is deposited on valve plate 2
On dust under gravity the surface of valve plate 2 fallen from the bottom of valve plate 2, it is to avoid the quilt in opening process of valve plate 2
Dust is blocked.
Wherein, in addition to the second connecting tube 6, the bottom of the second connecting tube 6 and the open communication of lower pipeline, valve body
4 bottom is connected by the second connecting tube 6 with lower pipeline.
Finally it should be noted that：Above example only to illustrate invention technical scheme, rather than its limitations；Although ginseng
Invention is described in detail according to previous embodiment, it will be understood by those within the art that：It still can be right
Technical scheme described in foregoing embodiments is modified, or carries out equivalent substitution to which part technical characteristic；And this
A little modifications are replaced, and the essence of appropriate technical solution is departed from the spirit and scope of each embodiment technical scheme of invention.
