Background technology
Outlet valve is usually to ensure that the material after reacting or being dry can be smoothly mounted on reaction or dry mixed device bottom
The valve of discharge.Outlet valve can be divided into whole ball valve and semisphere valve by structure division, discharge for powder, too big valve, whole ball
Valve generally uses powder semisphere valve as outlet valve because of the too big no operability of driving torque.Currently, in pharmaceutical chemical industry industry
Powder outlet valve, either hemisphere or whole ball valve, all there is there are one behind spool upper surface and container lower surface installation
Segment distance forms a dead cavity, the promotion for causing the material being deposited in dead space body to be not involved in reaction or cannot stir,
To be unable to get good reaction condition or drying condition, cause this partial material unqualified.It is stirred etc. and is done using hot nitrogen air-blowing
Method cannot be solved, and especially in the crystallization reaction of drug and drying, the dead material of deposition forms underproof hard material,
It results in blockage and blowing and directly influences the lot inspection quality of product.

The technical solution adopted in the utility model is as follows：
A kind of novel no dead angle powder outlet valve of the utility model, including driving, holder, shaft, spool left support bar, valve
Body, spool right support bar, sealing ring one, segment-shaped spool, valve seat, sealing ring two, small axis, spray ball and cleaning solution circulation pipe
Road；The drive connection shaft, shaft pass through valve body side axis hole and are connected with spool left support bar；Described is driven through
Holder is indirectly connected with valve body side；The small axis is symmetrically set across valve body other side axis hole with shaft in the same horizontal line
It sets, and is connected with spool right support bar；The inboard two of the spool left support bar and spool right support bar and segment-shaped spool
End is connected, and is located at the diameter both ends of segment-shaped spool；The valve seat is close by sealing ring one with segment-shaped spool
Envelope；The valve seat is sealed with container by sealing ring two；The spray ball is connected with cleaning solution circulation line one end, cleaning
Liquid circulation line is exposed at across one side opening of valve body except valve body, and on-line cleaning is carried out to outlet valve inside by installing automatic valve.
Further, the upper surface of the segment-shaped spool and the same arc of container inner wall.
Further, the segment-shaped spool rotates round center line and valve during opening and closing rotation
The eccentric distance of body theoretical centerline is 2 ~ 6mm so that segment-shaped spool generates upward displacement when being contacted with valve seat, to obtain
Obtain the vertical positive power of segment-shaped spool and sealing ring one.
Further, the body top is bolted with valve seat.
Further, the driving is connected with shaft by shaft coupling.
Further, the segment-shaped spool and spool left support bar, spool right support bar, shaft, small axis are prefabricated
Integral piece.
Further, the cleaning solution circulation line and valve body are by being weldingly connected.
Further, entire outlet valve is generally fixed to immediately below container.
The beneficial effects of the utility model：
The utility model is applied as a kind of in the common crystallization reactor of pharmaceutical chemical industry industry production, drier, siccative
Outlet valve in the equipment such as mixer, especially as the effect of the outlet valve in the equipment for having solid phase reaction or powder material discharging
Ensure not having the dead material for being not involved in reaction presence without dead angle with container after closing with segment-shaped spool that advantage is outlet valve,
The non-uniform phenomenon of material stirring is avoided, the total quality of material is substantially increased, and has sufficiently large latus rectum to ensure object
Expect without hindrance releasing, prevent feed blocking, improve whole work efficiency, extends the service life of outlet valve.
The utility model is that hemisphere spool is changed to segment-shaped spool in structure, and upper surface is with inner surface of container shape
Change and is consistent；Transmission shaft moves up, and valve body presses the increase of the spool radius of gyration, realizes spool upper surface and inner surface of container pair
It is flat, obtain no dead angle effect；Change spool from transmission principle and contact sealing with sealing ring spin friction, become spool with it is close
Seal eccentric jam mode effectively extends sealing life, improves sealing reliability.Segment-shaped spool is after closing, segment-shaped valve
The upper surface of core preserves value with container inner wall in a cambered surface or plane, and after segment-shaped spool turns on, segment-shaped spool is hided in valve
Body side surface concedes the smooth discharge that enough latus rectums make powder without hindrance.Due to being in one with container junction after closing
In cambered surface or plane, therefore there is no dead angle cavitys, and there is no the dead material presence for being not involved in reaction.
