Description
Technical field
The utility model relates to a kind of valve field, specially a kind of inflation sealing valve.
Background technique
It is usually used in controlling the inflation sealing valve of fine-grained powder disengaging, also referred to as top dome valve, spool is vaulted body.When
After spool is in the closed position, it need to be inflated to Expansion sealing circle, Expansion sealing circle will be close to vaulted body, Cai Nengshi after by compression swelling
The closing of existing inflation sealing valve.When valve is opened, Expansion sealing circle sealing gas need to be first bled off, then open spool.Expansion
Sealing ring can just open or close spool in non-aerating state.This spool is the vaulted body of hemisphere face, when opening and closing
Vaulted spherical surface has certain gap in Expansion sealing circle.
Inflation sealing valve is used under normal circumstances, since vaulted spherical surface has certain gap, valve in Expansion sealing circle
Core switchs almost without rubbing and damaging.But if there are the foreign matters such as slightly larger particle, sundries, rope band to stay in powder particles
On vaulted spherical surface, once these foreign matters are left with the opening of spool, they will be among the contract angle of spool and valve deck
Enter Expansion sealing circle with the opening of spool, Expansion sealing circle will damage quickly, cause valve seal to fail, and then further
Accelerate the damage of spool, valve is scrapped.Therefore to improve the structure of inflation sealing valve, allow to extend top dome spool and
The service life of Expansion sealing circle.
Utility model content
The purpose of this utility model is to provide a kind of inflation sealing valve, with solve in existing product top dome spool and
The problem of Expansion sealing circle is quickly damaged.
To achieve the above object, the utility model provides the following technical solutions:
A kind of inflation sealing valve, including it is switching spool driving device, valve seat, driving revolution long axis, inflatable interface, swollen
Swollen sealing ring, spool, valve deck and short supporting axle, valve seat left side top are equipped with short supporting axle, set above the short supporting axle
There is valve deck, top is equipped with driving revolution long axis on the right side of the valve seat, connection switching spool driving on the right side of the driving revolution long axis
Device, the spool be truncated conical shape, section be " [" type, the spool be mounted on driving revolution long axis and short supporting axle on, and
It can be along the opening and closing of driving revolution long axis and 90 ° of short supporting axle axial-rotation realization sealing valves, when spool is in close stance
When setting, Expansion sealing circle is inflated by inflatable interface, Expansion sealing circle is then adjacent to spool.
Furthermore, the driving revolution long axis and short supporting axle are equipped with keyway, and are connected by key spool.
Furthermore, it is equipped with gasket seal between the valve deck and valve seat, and is bolted.
Furthermore, switching spool driving device, switching spool driving are threadedly coupled on the right side of the driving revolution long axis
Device is simultaneously bolted on the right side of valve seat.
Compared with prior art, the utility model has the beneficial effects that a kind of inflation sealing valve is arranged, pass through improvement
Valve core structure can enable gap of the foreign matter for being mixed into fluid when valve is opened between spool and sealing ring be discharged, avoid different
Damage of the object to spool and sealing ring, so that the sealing valve service life increases, reliability increases.
The spool of the inflation sealing valve is truncated conical shape, and longitudinal cross-section is that " [" type can be prevented in valve core rotation
The foreign matters such as slightly larger particle, sundries, rope band stay on shape spherical surface in powder particles, these foreign matters can be with the opening of spool and from valve
It is flowed out in the crack of core rotary table and valve seat, to avoid the damage of Expansion sealing circle, extends the service life of Expansion sealing circle.
