The dynamic axial compression column piston is provided with a connecting seat, and a mobile phase inlet pipe is arranged in the connecting seat and connected with a distributor. The dynamic axial compression column piston is characterized in that a VP type sealing ring seat and a middle spacer are sequentially arranged between the connecting seat and the distributor, the connecting seat, the VP type sealing ring seat, the middle spacer and the distributor are sequentially connected with one another by bolts, an axial protection sealing ring is arranged at the edge of the joint of the interior of the connecting seat and the VP type sealing ring seat, a VP type sealing ring is arranged at the edge of the joint of the interior of the VP type sealing ring seat and the middle spacer, a bowl-shaped sealing ring is arranged at the edge of the joint of the interior of the distributor and the middle spacer, and the jointing surface of the VP type sealing ring seat and the middle spacer, as well as the jointing surface of the distributor and the middle spacer are respectively provided with an O-shaped sealing ring.
Description
Technical field:
The utility model relates to a kind of dynamic axial compression chromatography post, reliable, the simple load and unload dynamic axial compression column piston of especially a kind of sealing.
Background technology:
Along with the fast development of biological medicine and chemical, preparative liquid chromatography is widely used in the separation and purification field, and wherein the dynamic axial compress technique is one of the important technology in preparative chromatography field.In the dynamic axial compression chromatography post, the structure of piston design directly influences operability and sealing effectiveness, and its performance is to estimate an important indicator of chromatographic column quality.At present, dynamic axial compression column piston common on the market all has the piston Connection Block basically, the phase inlet tube that flows places in the Connection Block and directly is connected with the screwed hole of piston distributor, after flowing to the piston distributor when flowing by mobile phase inlet tube, will flow and sample is evenly distributed to chromatographic column post bed fast by distributor.But existing dynamic axial compression column piston (as the Φ 110 dynamic axial compression column pistons of French Novasep) big assembly, the monolithic constructions of adopting make troubles for the installation and removal of stream joint more.
Summary of the invention:
The utility model is for the existing above-mentioned technical problem of technical solution, provides a kind of sealing reliable, simple load and unload dynamic axial compression column piston.
Technical solution of the present utility model is: a kind of dynamic axial compression column piston, be provided with Connection Block, the phase inlet tube that flows places in the Connection Block and with distributor and joins, and it is characterized in that: be equipped with VP RunddichtringO seat, intermediate spacers between described Connection Block and the distributor successively and by bolt Connection Block, VP RunddichtringO seat, intermediate spacers and distributor be connected successively; In Connection Block, be provided with axial protection sealing ring with edge, VP RunddichtringO seat joint; in VP RunddichtringO seat, be provided with the VP RunddichtringO with edge, intermediate spacers joint; in distributor, be provided with a bowl RunddichtringO, on VP RunddichtringO seat and intermediate spacers and distributor and intermediate spacers abutted surface, be respectively equipped with the O RunddichtringO with edge, intermediate spacers joint.
The utility model adopts the multicompartment package assembly, makes the stream joint easy accessibility in the piston; Radially adopt O RunddichtringO flat seal and, guarantee that sealing is reliable by VP RunddichtringO, bowl RunddichtringO and the axially axial seal of protection sealing ring realization; Thereby guarantee to flow phase and sample all spread (do not have and leak) by distributor to post bed periphery, can realize stabilizing and increasing the effect of post effect.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment:
Below in conjunction with the description of drawings specific embodiment of the present utility model.As shown in Figure 1: equally be provided with Connection Block 1 with prior art, the phase inlet tube 10 that flows places in the Connection Block 1 and with distributor 9 and joins, and is equipped with VP RunddichtringO seat 3, intermediate spacers 6 between prior art different is Connection Block 1 and the distributor 9 successively and by bolt Connection Block 1, VP RunddichtringO seat 3, intermediate spacers 6 and distributor 9 is connected successively; VP RunddichtringO seat 3 inboards have bound edge that intermediate spacers 6 and distributor 9 are encased; in Connection Block 1, be provided with axial protection sealing ring 2 with edge, VP RunddichtringO seat 3 joint; in VP RunddichtringO seat 3, be provided with VP RunddichtringO 4 with edge, intermediate spacers 6 joint; in distributor 9, be provided with bowl RunddichtringO 8, be respectively equipped with O RunddichtringO 5,6 on VP RunddichtringO seat 3 and intermediate spacers 6 and distributor 9 and intermediate spacers 6 abutted surfaces with edge, intermediate spacers 6 joint.
