Description
Technical field
The utility model is related to a kind of butterfly valves, 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
Very little few, advantage with long service life 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 shell, corresponding circular through hole, upper end cover center, bottom end cover is arranged on valve plate in upper end cover, bottom end cover
Between center together by axis connection, valve plate is fixed on axis, in valve plate two sides and the inner wall being embedded in beside shell circular through hole
Sealing element form sealing, cylinder band moving axis rotation is swung in shell along 90 ° of axis is intermittent to drive valve plate, 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 shell import and export end is connect with blow-off line, butterfly valve housing distortion, valve can be made by outer force effect
Seat ontology (the protrusion plane near sealing element) generates displacement, causes valve plate dead by folder, butterfly valve catching phenomenon occurs.
Utility model content
Technical problem to be solved in the utility model is to overcome the above-mentioned insufficient of the prior art and provide a kind of butterfly valve, is made
It is not easy clamping stagnation.
The technical scheme in the invention for solving the above technical problem is：
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, valve plate
The upper corresponding through-hole of setting, between upper end cover center, bottom end cover center together by axis connection, valve plate is fixed on axis, valve plate
Driver drive valve plate is dynamic along shaft rotation, upper end cover, bottom end cover through-hole side setting rotating seal seal groove, sealing element places
In seal groove, it is characterised in that：It is approached 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
Respectively increase an opposite boss at center, and upper end cover and bottom end cover are fixed together by opposite boss.
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 utility model has the advantage of：Due to being provided with corresponding boss on upper end cover and bottom end cover, can carry
Intensity and rigidity after high butterfly valve shell connection, to prevent to generate phase between the seal groove of upper end cover and the seal groove of bottom end cover
To displacement, valve plate is avoided to be stuck the appearance of phenomenon.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model embodiment butterfly valve.
Fig. 2 is that the utility model embodiment butterfly valve 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 implementation mode
Below in conjunction with the accompanying drawings, embodiment further illustrates the utility model.
As shown in Figure 1, 2, butterfly valve comprising upper end cover 1, bottom end cover 2, cylinder 7, valve plate 4.
Material through hole 13 is arranged in upper end cover 1, and 13 inside of material through hole is arranged seal groove 14, sealing element is placed in seal groove 14
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, material through hole 23 is arranged in bottom end cover 2, and 23 inside of material through hole is arranged seal groove 24, is placed in seal groove 24
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 is set in above-mentioned sealing element 6, puts a flexible silicon sebific duct 11 in U-lag 61, makes
The preferably sealing valve plate 4 of sealing element 6.
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 cylinder 7 acts energy band turn axis 5 and makees intermittent 90 ° of rotating forwards
Or reversion, to drive valve plate 4 to make intermittently 90 ° of swings centered on shaft 5, to make the material through hole 41 on valve plate 4
It is connected to or blocks with the material through hole 23 of the material through hole 13 of upper end cover 1 and bottom end cover 2, i.e., when the through-hole and end cap on valve plate 4
On through-hole overlap when be " butterfly valve is opened ", when valve plate 4 covers the through-hole on end cap be " butterfly valve pass ", to play discharge or resistance
The effect of material.
As shown in Fig. 2, occurring the catching phenomenon of valve plate in order to prevent, in the company of the diameter and axis 5 of the through-hole 13 of upper end cover 1
Respectively increase an opposite round boss 9 close to center on line 12, similarly, also increases close to center on the center line 12 of bottom end cover 2
Add an opposite round boss 9, is used in combination screw 3 to be fastenedly connected upper end cover 1 and bottom end cover 2 by round boss 9, thus
The strength and stiffness of butterfly valve shell 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 being arranged
The upper end cover center or bottom end cover center of shaft 5 are better.
In order to further prevent valve plate 4 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.
