Description
Technical field
The present invention relates to a kind of powder medicine to unload and put valve, particularly relate to a kind of discharging butterfly valve.
Background technique
Generally need use mixed powder machine in solid-state drug production technology, with each component Homogeneous phase mixing by medicine, the mixed powder machine applying to produce in enormous quantities completes the stirring that above mixing is generally each for medicine component is thrown by stirring apparatus to container and is realized.The bottom of said vesse is generally provided with a discharge of materials valve, simultaneously based on the form of powder fluid and in producing to the requirement rapidly of above-mentioned valve open/close, above-mentioned valve many employings butterfly valve, for avoiding occurring grunge pollution, above-mentioned butterfly valve many employings hand brake butterfly valve.
In prior art, the hand-activated braking mechanisms of butterfly valve is generally divided into worm and worm gear and tooth bar handle two kinds of structural types, and the arrestment mechanism of tooth bar handle formation can not use lubricant oil completely due to it, is the arrestment mechanism that butterfly valve in pharmacy corporation extensively adopts.But the part-structure that the arrestment mechanism of tooth bar handle formation is exposed in external environment because of it is complicated, is unfavorable for cleaning it, also easily there is with after the arrestment mechanism use certain hour of hour rack handle formation the situation that open and close are required great effort.
Summary of the invention
The part-structure be exposed in external environment because of it for the arrestment mechanism solving above-mentioned prior art middle rack handle formation is complicated, be unfavorable for cleaning it, with the problem also easily occurring the situation that open and close are required great effort after the arrestment mechanism use certain hour of hour rack handle formation, the invention provides a kind of discharging butterfly valve.
For the problems referred to above, the present invention solves problem by the following technical programs: a kind of discharging butterfly valve, comprise valve seat, the valve rod that the spool being arranged in valve base cavity is fixedly connected with spool with one end, the free end of described valve rod is positioned at the outside of valve seat, also comprise shaft-like handle, spring and draw-in groove seat, the end of valve rod free end is provided with bar-shaped trough, handling portion is positioned at bar-shaped trough, and handle and valve rod are articulated and connected by the hinged nail crossing bar-shaped trough, draw-in groove seat is fixedly connected on valve seat, draw-in groove seat is provided with multiple draw-in groove, handling portion is positioned at any one draw-in groove, one end of described spring and handle contact and be compressed between valve seat and handle, hinged nail is between spring and draw-in groove.
The handle arranged is used for actuate valve stem and rotates, and namely handle side and bar-shaped trough side interact and transmit torque on valve rod, last brake spool.The draw-in groove arranged is for limiting the rotation of handle relative to valve seat: after handle is arranged in any one draw-in groove, draw-in groove sidewall is held in draw-in groove by handle clamp.The spring arranged is used for preventing from departing from from draw-in groove at non-artificial situation lower handle: handle regards lever as, the tie point of hinged nail and handle is the fulcrum of lever, fulcrum two ends are spring and draw-in groove respectively, and the elastic force of spring is for using force, and draw-in groove side or bottom are resistance point.When needing to adjust the aperture of spool, apply pressure stress or tensile stress makes spring be further compressed on handle, handle exits from draw-in groove, then handle with sleeve can reach the object of adjustment spool aperture.
Further technological scheme is:
Described draw-in groove seat is tubular, and one end of draw-in groove seat is fixedly connected on valve seat, and draw-in groove is arranged on the free end of draw-in groove seat, and the axial direction of valve rod is parallel with the axial direction of draw-in groove seat, and valve stem part is positioned at the hollow region of draw-in groove seat.More than arrange and be convenient to arrange draw-in groove in draw-in groove seat end along draw-in groove seat circumferential direction, when the pocket numbers arranged is equal, the draw-in groove seat of above structural type, compared to other structural type, has the advantages that volume is little.
Also comprise the follower block be fixed on valve rod, the side of described draw-in groove seat free end is also provided with the arc notch of an arc length in draw-in groove seat girth 1/1 to two/3rd scope, draw-in groove is distributed in the region on free end beyond arc notch, and described follower block is arranged in arc notch.The follower block arranged, for limiting the rotation angle of valve rod, also can be used as the instruction of spool open and close state simultaneously, is conducive to occurring when preventing spool from closing not tight leaking material or causing wearing and tearing when aperture is excessive and closing force is excessive to the sealing surface on valve seat and spool.
The two ends of described spring respectively with follower block and handle contact.More than arrange and be intended to spring to be arranged between follower block and handle, spring is rotated with valve rod constant angular velocity, avoids the spring excessive distortion when regulating butterfly valve aperture.
Described follower block is also provided with blind hole, and spring section is positioned at blind hole.Because spring needs to be in compressive state, after spring one end is arranged in blind hole, spring can be limited in blind hole, avoids at least one end of spring to fix, thus convenient installation and replacing spring.
The outside of described spring is also arranged with dust-separation cover.The dust-separation arranged overlaps and is used for spring and extraneous isolation, and avoiding dust to enter into inside spring affects daily the cleaning of butterfly valve.Dust-separation cover can adopt the soft cover such as rubber sleeve or cloth cover.
The present invention compared with prior art, has following beneficial effect:
In the present invention; the brake member of valve rod is only handle; the stop component of valve rod is only draw-in groove and spring; above structural type does not in use need lubrication protection; simultaneously compared to the tooth bar handle arrangement form of butterfly valve in prior art, have the advantages that structure is simple, dead angle part is few, brake drag is little.Structure of the present invention is simple, easy to manufacture and easy to operate, easy to clean, is beneficial to the clean requirement meeting mixed powder machine discharge port near zone.
