Embodiment
The utility model is described in further detail presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram,
Only illustrate basic structure of the present utility model in a schematic way, therefore it only shows the composition relevant with the utility model.
As Figure 1-4, a kind of ventilation valve of good sealing effect, including annular housing 1 and the door that is arranged on housing 1
2, the door 2 is semicircle, and two doors 2 form circle, and the circular diameter that two doors 2 are formed is more than the straight of the inner ring of housing 1
Footpath, connected by connector 4 between two doors 2, the connector 4 includes upper bed-plate 10, lower bottom base 11 and connecting pole 9, described
Upper bed-plate 10 and lower bottom base 11 are arranged on the anchor ring of housing 1, pass through connecting pole 9 between the upper bed-plate 10 and lower bottom base 11
Connection, the connecting pole 9 are located on the straight line where the diameter of housing 1, and circle is equipped with the upper bed-plate 10 and lower bottom base 11
Connected in star 12, the groove 12 on the upper bed-plate 10 are set with the face of groove 12 on lower bottom base 11；
