Description
Technical field
The utility model relates to a kind of air valve door for sack cleaner, relates to a kind of yielding support formula air valve door specifically.
Background technique
Existing a kind of air valve door for sack cleaner, mainly comprise housing, turnover panel, transmission shaft, connecting rod and weight, transmission shaft is installed on housing, turnover panel is positioned at housing and is arranged on transmission shaft, one end of connecting rod is arranged on transmission shaft one end, and weight is positioned at the outside of housing and is arranged on the other end of connecting rod.In normal state, the bottom and upper segment of turnover panel is close on an interior surface of the housing, because turnover panel must overturn when ash discharge, there is gap, therefore poor sealing performance during design between the dual-side of turnover panel and the internal surface of housing.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of yielding support formula air valve door of good seal performance.
For solving the problems of the technologies described above, a kind of yielding support formula of the utility model air valve door, containing valve body, spool, spring, guide rod, nut and screw rod, valve body comprises the cylindrical body on top and the casing of bottom, the end opening of cylindrical body is arranged on the end face of casing, the suitable for reading of cylindrical body is material feeding mouth, the end face of casing is provided with the through hole matched with cylindrical body end opening, the lower end of casing is discharge port, spool is cone, the end opening being arranged in described cylindrical body of this cone, one end of guide rod is arranged on the bottom center of this cone, the upper end of screw rod is provided with adjustment cap, screw rod is provided with pilot hole, the other end of guide rod is installed in the pilot hole that screw rod is provided with, spring housing dress on the guide bar, the upper end of spring is attached to the bottom of spool, the other end of spring is attached in the adjustment cap of screw rod upper end, screw rod is installed on nut, nut is by the central authorities of Bracket setting at described casing.
In above-mentioned yielding support formula air valve door, the spool being cone due to structure is close in the end opening of cylindrical body by spring, therefore good seal performance.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model yielding support formula air valve door.
1. cylindrical bodys, 2. spool, 3. spring, 4. guide rod, 5. adjustment cap, 6. screw rod, 7. nut, 8. casing, 9. support in figure.
Embodiment
In Fig. 1, a kind of yielding support formula air valve door, containing valve body, spool 2, spring 3, guide rod 4, nut 7 and screw rod 6.Valve body comprises the cylindrical body 1 on top and the casing 8 of bottom, and the end opening of cylindrical body 1 is arranged on the end face of casing 8, and the suitable for reading of cylindrical body 1 is material feeding mouth, and the end face of casing 8 is provided with the through hole matched with cylindrical body 1 end opening, and the lower end of casing 8 is discharge port.Spool 2 is cone, the end opening being arranged in described cylindrical body 1 of this cone.One end of guide rod 4 is arranged on the bottom center of this cone, and the upper end of screw rod 6 is provided with adjustment cap 5, and screw rod 6 is provided with pilot hole, and the other end of guide rod 4 is installed in the pilot hole that screw rod is provided with.Spring 3 is sleeved on guide rod 4, and the upper end of spring 3 is attached to the bottom of spool 2, and the other end of spring 3 is attached in the adjustment cap 5 of screw rod 6 upper end, and screw rod 6 is installed on nut 7, and nut 7 is arranged on the central authorities of described casing 8 by support 9.Under normal state, structure in above-mentioned yielding support formula air valve door is that the spool 2 of cone is close to by spring 3 in the end opening of cylindrical body 1, when the powder in cylindrical body 1 reaches a certain amount of, the deadweight of powder overcomes the elastic force of spring 3, spring 3 is compressed, spool 2 moves down, at this moment the powder in cylindrical body 1 enters casing 8 from flowing out between spool 2 surface and the end opening of cylindrical body 1 of cone, then discharged by the discharge port of casing 8 lower end, last spring 3 resets, and is close in the end opening of cylindrical body 1 by the spool 2 of cone.Carried out the compression height of Regulation spring 3 by adjustment cap 5 rotating screw bolt 6, so just can regulate the powder height in cylindrical body 1, to reach the object of lock wind further.
