Description
Technical field
The present invention relates to a kind of powder medicine and unload and put valve, particularly relate to a kind of discharging butterfly valve.
Background technique
In solid-state drug production technology, generally need use mixed powder machine, so that each component of medicine is evenly mixed, the mixed powder machine that applies to produce in enormous quantities completes above mixing and is generally each medicine component is thrown to container and realized by the stirring of stirring apparatus.The bottom operated by rotary motion of said vesse has a discharge of materials valve, simultaneously the form based on powder fluid and produce in to the requirement rapidly of above-mentioned valve open/close, above-mentioned valve adopts butterfly valve more, and for avoiding occurring grunge pollution, above-mentioned butterfly valve adopts hand brake butterfly valve more.
In prior art, the hand brake mechanism of butterfly valve is generally divided into worm and worm gear and two kinds of structural types of tooth bar handle, and the arrestment mechanism of tooth bar handle form is because it can not use lubricant oil completely, is the extensively arrestment mechanism of employing of butterfly valve in pharmacy corporation.But the arrestment mechanism of tooth bar handle form, because it is exposed to the part-structure complexity in external environment, is unfavorable for it to clean, after the arrestment mechanism use certain hour with hour rack handle form, be also prone to the situation of open and close effort.
Summary of the invention
For the arrestment mechanism that solves above-mentioned prior art middle rack handle form is exposed to the part-structure complexity in external environment because of it, be unfavorable for it to clean, the problem that is also prone to the situation of open and close effort after arrestment mechanism use certain hour with hour rack handle form, 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, be arranged in the valve rod that the spool of 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 that crosses bar-shaped trough, draw-in groove seat is fixedly connected on valve seat, on draw-in groove seat, be provided with multiple draw-in grooves, handling portion is positioned at any one draw-in groove, one end of described spring contacts and is compressed in handle between valve seat and handle, hinged nail is between spring and draw-in groove.
The handle arranging rotates for actuate valve stem, and handle side and bar-shaped trough side interact and transmit torque on valve rod, last brake spool.The draw-in groove arranging is for limiting the rotation of handle with respect to valve seat: handle is positioned at after any one draw-in groove, and draw-in groove sidewall is held in draw-in groove by handle clamp.The spring arranging is used for preventing departing from from draw-in groove at non-artificial situation lower handle: handle is regarded lever as, the tie point of hinged nail and handle is the fulcrum of lever, fulcrum two ends are respectively spring and draw-in groove, and the elastic force of spring is for using force, and draw-in groove side or bottom are resistance point.In the time need to adjusting the aperture of spool, to applying pressure stress on handle or tensile stress is further compressed spring, handle exits from draw-in groove, then handle with sleeve can reach the object of adjusting 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 be convenient to along draw-in groove seat circumferential direction, draw-in groove is set in draw-in groove seat end, in the case of arrange draw-in groove quantity equal, the draw-in groove seat of above structural type, than other structural type, has the advantages that volume is little.
Also comprise the follower block being fixed on valve rod, the free-ended side of described draw-in groove seat is also provided with the arc notch of an arc length in draw-in groove seat girth 1/3rd to 1/2nd scopes, draw-in groove is distributed in the region beyond arc notch on free end, and described follower block is arranged in arc notch.The follower block arranging, 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 prevent when material from appearring leaking in spool closure when tight or excessive and closing force is excessive in aperture the sealing surface on valve seat and spool is caused to wearing and tearing.
The two ends of described spring contact with handle with follower block respectively.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, avoid spring excessive distortion in the time of regulating butterfly valve aperture.
In described follower block, be also provided with blind hole, spring section is positioned at blind hole.Because spring need to be in compressive state, when spring one end is arranged in after blind hole, spring can be limited in blind hole, avoid 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 cover arranging is used for, by spring and extraneous isolation, avoiding dust to enter into spring inner side and affecting 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, there is feature simple in structure, that dead angle part is few, brake drag is little.The present invention is simple in structure, easy to manufacture and easy to operate, easy to clean, is beneficial to the clean requirement that meets mixed powder machine discharge port near zone.
