Description
Technical field
The present invention relates to the whole Interface design of equipment external catheter bunch, the whole Interface design of particularly a kind of multichannel fluid distributor and its external catheter bunch.
Background technique
Field of analytic instrument need be used a large amount of multichannel fluid distributors, for example multiposition valve, stream switch etc.These equipment tend to connect a lot of external catheters; For as surpass 8 multiposition valve or stream switch more than the port; The connection interface of its external catheter bunch and fluid distributor takes up space and increases gradually; Attended operation is complicated gradually, and therefore, the Interface design of the external catheter of multichannel fluid distributor bunch is one of important component part in the fluid distributor design.
Fig. 1 has shown the Cheminert multiposition valve structural representation (http://www.vici.com/cval/cval.php) of Valco Instruments Co.Inc. company; The place ahead of main valve body 3 is a fixed valve plug 1; Be processed with some fluid passages in the fixed valve plug 1, comprise common fluid passageway and a some distributing fluids passage that is distributed on the same circumference that is positioned at central authorities.Each above-mentioned fluid passage links to each other in some external catheters of multiposition valve and the fixed valve plug 1.One movable valve plug 2 is installed in the inside of multiposition valve main valve body 3, with fixed valve plug 1 through bolt to main valve body 3 tighten up fixing after, fixed valve plug 1 constitutes sealing surface with the surface of contact of movable valve plug 2.Be processed with a conducting groove on the sealing surface of movable valve plug 2, be adjacent under the situation of sealing at movable valve plug 2 and fixed valve plug 1, said conducting groove can be communicated with fixed valve plug 1 central fluid channel and peripheral distributing fluids passage.When rotating to different amount under the drive of movable valve plug 2 motor in main valve body 3, can the different distribution channel connections on the common fluid passageway of fixed valve plug 1 central authorities and fixed valve plug 1 outer ring be realized that the distribution of convection cell is controlled.
In known systems; The Interface design of the external catheter that is connected with multiposition valve bunch is as shown in Figure 2: be processed with several tapped holes 13 in the outer end of fixed valve plug 11 each fluid passage 12 (perhaps constituting on the valve body of fixed relationships with fixed valve plug 11); Each conduit 16 in the external catheter bunch passes the inipple 15 of a band central through bore separately; Insert in the fixed valve plugs 11 in the corresponding fluid passage 12 conduit 16 front end sleeve upper sealing washers 14 back; Behind the threaded together joint 13, can seal washer 14 be pressed in fluid passage 12 in the outer part on the step end face 17 of an end tightly, seal washer 14 inwardly squeezes the back by compression simultaneously; Conduit 16 is extruded a groove and tightly compressing, extracted easily by external force to prevent conduit 16.At seal washer 14 and conduit 16, and under the acting in conjunction of seal washer 14 and the sealing of 17 of fluid passage step end faces, can realize the sealing of corresponding fluids passage 12 in external each conduit 16 and the fixed valve plug 11.
