Embodiment 1
As shown in figure 1, the utility model provides a kind of pipeline valve, the valve includes rotating shaft 1, valve plate 2, drive mechanism
And be 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 and radially extends
Depression bar 1-1, i.e., there is the axis of angle or depression bar 1-1 perpendicular to rotating shaft 1 between the axis of depression bar 1-1 and the axis of rotating shaft 1
Axis, the middle part of depression bar 1-1 and valve plate 2 rotates and is connected, and drive mechanism rotates for drive shaft 1, so that valve plate 2 can be opened and closed
In the opening for being closed pipeline.
Thus, when need close be closed the opening of pipeline when, start drive mechanism, make drive mechanism drive rotating shaft 1 to
The direction rotation for being closed pipeline is provided with, 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, valve plate 2 can occur slight change with respect to the angle of depression bar 1-1 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 first contact with the opening for being closed pipeline, in valve plate
During 2 progressively close off the opening for being closed pipeline, valve plate 2 can adjust itself by the fine rotation of relative depression bar 1-1
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
Pressure distribution after generation, and 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 part of seal 2-2 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 on the opening for be closed pipeline, the seal 2-2 being not embedded into groove is plugged in and is closed pipe just
In the opening in road, dust is caused when the opening or sealing plate 2-1 out-of-flatnesses that are closed pipeline produce gap so as to avoid
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 closely 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, the area of sealing plate 2-1 is more than the area of 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, carried
Valve plate high 2 closes the accuracy and speed of 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 with valve body 4 by two bearings be connected respectively, 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, dust is easily deposited in drive mechanism, and then worn and torn when causing drive mechanism to be run；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 that connecting rod 3-2 and cylinder 3-1, cylinder 3-1 are rotatably connected on the outer of valve body 4
Side, one end of connecting rod 3-2 is connected with the piston rod rotation of cylinder 3-1, 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
Collective effect lower rotary shaft 1 with cylinder 3-1 is rotated according to specified angle.
Embodiment 2
With reference to shown in Fig. 2 to Fig. 4, the utility model additionally provides a kind of cleaning shaft, the pipeline include upper pipe, under
Portion's pipeline, the first connecting tube 5 and above-mentioned pipeline valve, upper pipe are located at the top of lower pipeline, the top of the first connecting tube 5
End and the open communication of upper pipe, the top of valve body 4 is connected by the first connecting tube 5 with upper pipe, bottom is with
Portion's pipeline connection, 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
End.
The structure of the 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 for gradually closing
In, the top of valve plate 2 first contacts 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 valve plate 2 surface from
The bottom of valve plate 2 falls, so as to dust can be avoided to be 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 first separates 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, also including 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 is only used to illustrate the technical scheme of utility model, rather than its limitations；To the greatest extent
Pipe has been described in detail to utility model with reference to the foregoing embodiments, it will be understood by those within the art that：Its according to
The technical scheme described in foregoing embodiments can so be modified, or which part technical characteristic is equally replaced
Change；And these modifications or replacement, the essence of appropriate technical solution is departed from each embodiment technical scheme of utility model
Spirit and scope.
