Description
Technical field
The present invention relates to a kind of butterfly valve, more particularly to a kind of butterfly valve for vacuum feces collecting system.
Background technology
Used blowdown butterfly valve in ater supply and drainage for railways system, because with simple in structure, small, light-weight, installation ruler
It is very little few, it the advantages of service life is long, is widely used in the nearly more than ten years.
Existing butterfly valve includes upper end cover, bottom end cover, valve plate, sealing element, cylinder, and upper and lower end cap is tight by periphery screw
It is solidly connected, forms butterfly valve housing, upper end cover, bottom end cover set corresponding circular through hole, upper end cover center, bottom end cover on valve plate
Between center by axis connection together, valve plate is fixed on axis, in valve plate two sides and the inner wall being embedded in beside housing circular through hole
Sealing element form sealing, cylinder band moving axis rotation swings so as to drive valve plate in housing along 90 ° of axis is intermittent, when on valve plate
Circular through hole when being communicated with the circular through hole of upper end cover, bottom end cover, can be opened through butterfly valve discharge, i.e. butterfly valve；When on valve plate
Circular through hole and upper end cover, bottom end cover circular through hole it is obstructed when, material just can not pass through butterfly valve, i.e. butterfly valve is closed.
When butterfly valve housing import and export end is connect with blow-off line, it can be acted on by external force and make butterfly valve housing distortion, valve
Seat ontology (the protrusion plane near sealing element) generates displacement, causes valve plate dead by folder, butterfly valve catching phenomenon occurs.
Invention content
The technical problems to be solved by the invention are to overcome the above-mentioned insufficient of the prior art and provide a kind of butterfly valve, make it not
Easy clamping stagnation.
Technical solution is used by the present invention solves the above problems：
A kind of butterfly valve, including upper end cover, bottom end cover, valve plate, sealing element, valve plate driver, upper end cover, bottom end cover are set on valve plate
Corresponding through-hole is put, between upper end cover center, bottom end cover center by axis connection together, valve plate is fixed on axis, valve plate driving
Device drive valve plate is moved along shaft rotation, upper end cover, bottom end cover through-hole side setting rotating seal seal groove, sealing element is placed on close
In sealing groove, it is characterised in that：Close to center on the diameter of the through-hole of the upper end cover and bottom end cover and the extended line of the line of centres
Locate one opposite boss of each increase, and pass through opposite boss and upper end cover and bottom end cover are fixed together.
More specifically, above-mentioned valve plate driver can be cylinder, oil cylinder or other can make axis rotate device.
Preferably, the gap S ＞ 0 between above-mentioned upper end cover seal groove top surface and valve plate opposite face, the bottom end cover sealing
Gap S ＞ 0 between groove top face and valve plate opposite face, such valve plate is less susceptible to stuck in use.
Preferably, the sealing element in above-mentioned upper end cover and upper end cover seal groove bottom contact surface are plane, with valve plate contact surface
For arc surface；Sealing element and bottom end cover seal groove bottom contact surface in the bottom end cover are plane, are circular arc with valve plate contact surface
Face.
Preferably, above-mentioned boss is round boss.
The advantage of the invention is that：Due to being provided with corresponding boss on upper end cover and bottom end cover, butterfly can be improved
Intensity and rigidity after valve chest connection, so as to prevent that opposite position is generated between the seal groove of upper end cover and the seal groove of bottom end cover
It moves, valve plate is avoided to be stuck the appearance of phenomenon.
Description of the drawings
Fig. 1 is the structure diagram of butterfly valve of the embodiment of the present invention.
Fig. 2 is that butterfly valve of the embodiment of the present invention removes the view after bottom end cover.
Fig. 3 is the left view of Fig. 1.
Fig. 4 is the partial view amplified in Fig. 1.
Specific embodiment
Below in conjunction with the accompanying drawings, the present invention is further described for embodiment.
As shown in Figure 1, 2, butterfly valve, including upper end cover 1, bottom end cover 2, cylinder 7, valve plate 4.
Upper end cover 1 sets material through hole 13, and 13 inside setting seal groove 14 of material through hole, seal groove 14 is interior to place sealing element
6, the one side 62 that upper end cover valve seat body 15 is exposed on sealing element 6 is close to valve plate 4 and forms sealing.
Equally, bottom end cover 2 sets material through hole 23, and 23 inside setting seal groove 24 of material through hole, seal groove 24 is interior to be placed
Sealing element 6, the one side 62 that bottom end cover valve seat body 25 is exposed on sealing element 6 are close to valve plate 4 and form sealing.
Upper end cover 1 and 2 periphery of bottom end cover are fixed by screw 8, and upper end cover 1 and bottom end cover 2 are centrally through shaft 5, axle sleeve 7
It links together.
Material through hole 41, through-hole 41 and material on material through hole 13 on upper end cover 1 and bottom end cover 2 are designed on above-mentioned valve plate 4
Through-hole 23 is corresponding, and 4 center of valve plate is fixed in shaft 5, and can be rotated with shaft 5,
Preferably to seal, U-lag 61 in above-mentioned sealing element 6 is set, a flexible silicon sebific duct 11 is put in U-lag 61, makes sealing
Part 6 preferably seals valve plate 4.
Preferably, the sealing element 6 in above-mentioned upper end cover seal groove 14 and upper end cover slot bottom contact surface 63 are plane, with valve plate
4 contact surface 62 is arc surface.
Preferably, the sealing element 6 in above-mentioned bottom end cover seal groove 24 and bottom end cover slot bottom contact surface 63 are plane, with valve plate
Contact surface 62 is arc surface.
Above-mentioned cylinder 7 connects shaft 5 by link mechanism, and the action of cylinder 7 can drive shaft 5 to make intermittent 90 ° of rotating forwards
Or reversion, so as to which valve plate 4 be driven to make intermittently 90 ° of swings centered on shaft 5, so as to make the material through hole 41 on valve plate 4
It connects or blocks with the material through hole 13 of upper end cover 1 and the material through hole 23 of bottom end cover 2, i.e., when the through-hole and end cap on valve plate 4
On through-hole when overlapping for " butterfly valve is opened ", be " butterfly valve pass " when valve plate 4 covers the through-hole on end cap, so as to play discharge or resistance
The effect of material.
As shown in Fig. 2, occurs the catching phenomenon of valve plate in order to prevent, in the diameter of the through-hole 13 of upper end cover 1 and the company of axis 5
Respectively increase an opposite round boss 9 close to center on line 12, similarly, also increase close to center on the center line 12 of bottom end cover 2
Add an opposite round boss 9, and be fastenedly connected upper end cover 1 and bottom end cover 2 by round boss 9 with screw 3, thus
The strength and stiffness of butterfly valve housing are substantially increased, valve plate 4 can be prevented stuck by upper end cover 1, bottom end cover 2.
Above-mentioned round boss 9 can be according to actual conditions, as long as in the case that not stopping valve plate 4, closer to placement when setting
The upper end cover center or bottom end cover center of shaft 5 are better.
In order to which valve plate 4 is further prevented to press from both sides dead possibility by upper end cover 1 and bottom end cover 2, also push up upper end cover seal groove 14
Gap S ＞ 0 between 4 opposite face 41 of face 15 and valve plate（See Fig. 4）, similarly, 24 top surface 25 of bottom end cover seal groove is opposite with valve plate 4
Gap S ＞ 0 between face 42（See Fig. 4）, accordingly even when still generating certain displacement between upper end cover 1 and bottom end cover 2, but also can
The gap S being increased is digested, and valve plate 4 will not press from both sides extremely.
