Abstract
The utility model discloses a powdery material discharging valve, and relates to a powdery material discharging technology, in particular to a discharging valve for cement and raw cement powder. The powdery material discharging valve comprises a casing, wherein a transversely arranged valve shaft is supported in the casing; two ends of the valve shaft are supported on the casing through a bearing and a bearing support respectively; one end of the valve shaft extends out of the casing; a valve core is connected onto the valve shaft in the casing; a sealing component is arranged in the casing; the bearing adopts an oscillating bearing; and two wave-shaped elastic gaskets are arranged at two ends of the valve shaft respectively and arranged between the valve core and the casing. According to the powdery material discharge valve, the bearing adopts the oscillating bearing, can bear radial and axial loads, has larger load capacity and shock resistance capacity, and is self-aligning and self-lubricating; and the wave-shaped elastic gaskets are mounted between the casing and the valve core, so that damping between the casing and the valve core is effectively improved, and flaking off and elastic deformation caused by vibration are prevented.
Description
Technical field
The utility model relates to powdery material unloading technology, the discharge valve of especially a kind of cement and cement raw meal.
Background technique
Existing powdery material discharge valve (patent No. is 200720131845X) mainly comprises housing, the valve shaft of a lateral arrangement of housing inner support, the two ends of valve shaft are supported on housing by bearing and bearing support respectively, one end of valve shaft stretches out in housing, on valve shaft in housing, connect spool, the bearing of this structure is plain bearing, and radial and axial load is born poor, load-carrying ability and impact resistance are poor, can not Self-aligning, selflubricating.Between housing and spool, there is no damping in addition, vibration easily comes off and resiliently deformable.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of powdery material discharge valve is provided, and has larger load-carrying ability and impact resistance, and has improved the damping between housing and spool.
The purpose of this utility model is achieved in that powdery material discharge valve, comprise housing, valve shaft in a lateral arrangement of housing inner support, the two ends of valve shaft are supported on housing by bearing and bearing support respectively, and one end of valve shaft stretches out in housing, on the valve shaft in housing, connect spool, black box is set in housing, described bearing is joint shaft bearing, at the two ends of described valve shaft, waveform bullet pad is set respectively, and two waveform bullet pads are separately positioned between spool and housing.
Bearing of the present utility model is joint shaft bearing, can bear radial and axial load, has larger load-carrying ability and impact resistance, Self-aligning, selflubricating.Waveform bullet pad is arranged between housing and spool, has effectively improved damping between the two, prevents from vibrating coming off and resiliently deformable of bringing.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 be in Fig. 1 C-C to view.
Embodiment
