Abstract
The invention discloses a multi-channel switching five-way valve for fluid. The concrete structure comprises that a bottom plate fixes a vertical plate, a left clamp plate and a right clamp plate integrally, and eight switching five-way valves are fixed on the vertical plate in peripheral arrangement. A motor is fixed on the left clamp plate. Four photoelectric couplers which are distributed in 90 degrees are fixed on the right clamp plate. A driving gear is mounted in a corresponding hole of the left clamp plate and the right clamp plate via a shaft, and the right end of the shaft of the driving gear is equipped with a shade piece. A main gear is mounted in the corresponding hole of the left clamp plate and the right clamp plate via a shaft, and eight planet gears which are arranged in a front row and a rear row are also mounted in the corresponding hole of the left clamp plate and the right clamp plate. The left ends of planet gear shafts are connected with the switching five-way valves via shaft couplings. A cone surface and a bottom surface of a valve core of the five-way valve are respectively equipped with a circular hole, a valve core bottom hole and a valve body bottom hole are concentric, and the circular hole of the cone surface of the valve core can be optionally communicated with four cone circular holes of the valve body, thereby forming five ways of inlet and outlet channels for fluid. The valve body has not residual fluid internally, thereby avoiding cross contamination caused by medicine detection, and the best choice for the medicine detection is to sample multiple times.
Description
Technical field
The invention belongs to fluid change-over valve, be specifically related to a kind of multi-channel switch five-way valve of sampling automatically when being used for liquid drug and detecting.
Technical background
Along with pharmaceuticals industry constantly develops, international and domestic all have strict vertification regulation to drug development and production.The suitable formulation of medicine stripping determination method is wider at present.Comprise tablet, capsule, granule, sustained release preparation, controlled release preparation, enteric coated preparations and the agent of transdermal card.The difference of drug dissolution experimental evidence formulation and difference, especially sustained release preparation and controlled release preparation dissolution test may reach several days, and sampling is often, now adopt the manual sampling complex operation, cycle is long, introduces personal error easily, makes the credibility that testing result is inaccurate and reduce measurement result.If when drug dissolution detects, adopt automatic sampling then above-mentioned defective corrected, but the control of detected medicine flow process is difficult to solve, adopt multi-channel switch five-way valve can satisfy the needs of taking a sample automatically when drug dissolution detects, improve the testing efficient of medicine and the accuracy of testing result.
Summary of the invention
The required multi-channel switch five-way valve of automatic sampling when the purpose of this invention is to provide the drug dissolution detection.When detecting, can finish drug dissolution the required flow direction of soup by the switching of valve body.
Structure of the present invention such as accompanying drawing, multi-channel switch five-way valve has: base plate 1, riser 2, left clamping plate 3, right clamping plate 4, switch five-way valve 5, motor gear 6, motor 7, photo coupler 8, driving gear 9, shading sheet 10, master gear 11, planetary pinion 12, coupling 13, spool 14, valve body 15, stage clip 16, poppet shaft 17, bonnet 18 etc.Concrete package assembly is: base plate 1 is fixed as one riser 2 left clamping plate 3 right clamping plate 4.8 switch five-way valves 5 are circumferential arrangement and are fixed in riser 2, constitute eight channel flow of fluid, and each passage can be realized the five-way conversion.The motor 7 that motor gear 6 is housed is fixed in left clamping plate 3 (as Fig. 1).4 photo couplers 8 respectively are divided into 90
0Be fixed in right clamping plate 4 (as Fig. 2).Driving gear 9 is by pack into the corresponding hole site of left clamping plate 3 and right clamping plate 4 of axle.The right-hand member that driving gear is 9 is equipped with shading sheet 10 (as Fig. 2).Master gear 11 is by pack into the corresponding hole site of left clamping plate 3 and right clamping plate 4 of axle.Two rows are by also pack into the corresponding hole site of left clamping plate 3 and right clamping plate 4 of axle before and after 8 planetary pinions 12 minutes.The left end that planetary pinion is 12 is connected with switch five-way valve 5 by coupling 13.Switch five-way valve 5 constitutes (as Fig. 3-4) by spool 14, valve body 15, stage clip 16, poppet shaft 17, bonnet 18 assemblings.Spool 14 front ends are cone, closely cooperate with valve body 15 internal taper holes.The conical surface of spool 14 and bottom surface respectively have a circular hole, two circular hole internal run-throughs.Spool 14 bottom outlets and valve body 15 bottom outlet concentrics, spool 14 conical surface circular holes can communicate arbitrarily with 4 conical surface circular holes of valve body 15, form the access way (as Fig. 5-6) of five road fluids.Poppet shaft 17 is set with stage clip 16, and poppet shaft 17 cooperates with spool 14 keyways, and poppet shaft 17 is fixed on the valve body 15 by bonnet 18.Be anti-liquid corrosion, the material of valve body 15 adopts polychlorotrifluoroethylene, and the material of spool 14 adopts teflon.

Embodiment
Below the present invention is described further by specific embodiment.Each parts is assembled by accompanying drawing.Present embodiment is eight passage switch five-way valves.Motor 7 energising drive motor gears 6 also drive driving gear 9 rotations, and driving gear 9 drives master gears 11 and rotates, and master gear 11 drives 8 planetary pinions 12 again and rotates, and drive 8 poppet shaft 17 on the switch five-way valve 5 simultaneously by 8 coupling 13 then and rotate.When the shading sheet on the driving gear 9 10 forwards A position photo coupler 8 to (as Fig. 2), motor 7 stops operating, at this moment spool 14 conical surface circular holes of 8 switch five-way valves 5 all are parked in A position (as Fig. 5), this moment, the liquid of 8 passages can be respectively flows into from the E mouth (as Fig. 5) of 8 valve bodies, behind spool 14 separately, from the A mouth outflow of valve body separately.When the shading sheet on the driving gear 9 10 forwards C position photo coupler 8 to (as Fig. 2), motor 7 stops operating, at this moment spool 14 conical surface circular holes of 8 switch five-way valves all are parked in C position (as Fig. 6), this moment, the liquid of 8 passages can be respectively flows into from the E mouth (as Fig. 5) of 8 valve bodies, behind spool 14 separately, from the C mouth outflow of valve body separately.In like manner, when the shading sheet on the driving gear 9 10 is parked in B position or D position photo coupler respectively (as Fig. 2), the liquid of 8 passages can flow out from B mouth or D mouth respectively.(as Fig. 4).Liquid is flowed into from the E mouth of valve body, flow out from A, B, C, each mouthful of D respectively.
Characteristics of the present invention are that electrical control is simple, valve body switches high conformity, can realize the flow direction of multichannel liquid.Valve body adopts polychlorotrifluoroethylene, and spool adopts teflon, can play corrosion resistant effect for the medicine that has the pharmaceutical chemistry composition, and the cross pollution that brings when not having residual liquid to avoid medicine to detect simultaneously in the valve body improves accuracy in detection.Repeatedly taking a sample when detecting for medicine is best choice.
