Abstract
The utility model discloses a high-efficiency general joint for a liquid-phase chromatographic column, comprising a hand-tightening screw cap, a locking edge ring, a push ring, an outer ring sleeve, a sealing edge ring and a stainless-steel capillary pipe. The outer ring sleeve is added outside the sealing edge ring to compose a sealing component, and the locking edge ring with inner screw threads is matched with the capillary pipe with outer screw threads by the screw threads so as to achieve the positioning purpose. The joint can be directly operated by hands to mount and dismount the chromatographic column and can adapt to being used for matching with the chromatographic column, having small dead volume of the connecting point, good sealing performance, repeated mounting and dismounting and long service life and raising the efficiency of the column.
Description
The utility model is an accessory of liquid chromatograph, and specifically one is used for the universal joint that the liquid-phase chromatographic column pipeline connects.
When using liquid chromatography to analyze, often kind and performance are selected different chromatographic columns per sample, and therefore the joint that is connected with chromatographic column is to install and remove parts repeatedly.Require the joint component favorable sealing property for reaching analytical effect well simultaneously, and the dead volume of junction should be very little.Biography around the post web member can only be suitable for the product post of a company, joint promptly lost efficacy after tens dismountings, therefore was difficult to be suitable for selecting the chromatographic column of different manufacturers model to use.There is kind of a chromatographic column joint that is called Dynaseal connection System in West Germany KNAUER company, by hand-tight nut, and opening sword ring and PEEK plastic seal sword ring, kapillary four parts are formed.When being connected with chromatogram, this joint, directly just can tighten with hand without spanner, favorable sealing property, and it is long-pending little to connect execution.But its sword ring and kapillary are the PEEK engineering plastics and make, and at present domestic this material pipeline is less and mostly be the Stainless Steel Capillary pipeline.In addition, it is relatively poor that this joint sword ring lock is decided effect, and serviceable life is also limited.
The purpose of this utility model provides a kind of general liquid chromatography column joint that the stainless steel capillary pipeline uses that is suitable for, it can connect the different model chromatographic column, and can load and unload long-term use repeatedly, and the dead volume of this joint junction is very little simultaneously, favorable sealing property can satisfy request for utilization.
The utility model performance liquid chromatographic column universal joint has improved present product, it comprises hand-tight nut equally, locking sword ring, and several parts of sealing sword ring and stainless steel capillary are formed, it is characterized in that sealing the sword ring and be added with the outer shroud cover outward, simultaneously locking sword ring and outside be added with a throw-out collar between the ring set.Locking sword ring, throw-out collar and outer ring set all can be made by stainless steel, and seal the sword ring by having elasticity, and the acid and alkali resistance material, and for example teflon is made.The same opening sword ring of locking sword ring of the present utility model, but the sword endless belt that stainless steel is made is by internal thread, and stainless steel capillary has external thread.Turn hand-tight nut with hand when being connected with chromatographic column, then promote locking sword ring forward, throw-out collar, outer ring set and sealing sword ring, during the stressed jam-packed of above-mentioned parts, sealing sword ring seals, the outer shroud cover covers sealing sword ring, prevent its stress deformation, the throw-out collar transmission is from the pressure of hand-tight nut, and locking sword ring is when stressed, cooperate with external thread on the kapillary by its internal thread and to do positioning and locking, can prevent to lock sword ring loose shift effectively.Below in conjunction with accompanying drawing structure of the present utility model is further described.
Accompanying drawing 1 is a liquid-phase chromatographic column universal joint structural drawing, and the joint of structure shown in Figure 1 also can be used as an embodiment of the present utility model.Among Fig. 1,1, hand-tight nut; 2, locking sword ring; 3, throw-out collar; 4, outer ring set; 5, sealing sword ring; 6, stainless steel capillary.By shown in Figure 1, the utility model universal joint comprises hand-tight nut 1, locking sword ring 2, throw-out collar 3, outer ring set 4, sealing sword ring 5 and stainless steel capillary more than 6 parts, the outside of sealing sword ring 5 is covered with outer shroud cover 4, adding throw-out collar 3 between locking sword ring 2 and outer ring set 4, above-mentioned locking sword ring 2 is similarly an opening sword ring and has internal thread, and has external thread on the stainless steel capillary 6.Sealing sword ring 5, outer ring set 4, throw-out collar 3, locking sword ring 2 and hand-tight nut 1 are enclosed within successively on the stainless steel capillary 6 and constitute joint.Wherein hand-tight nut 1, locking sword ring 2, throw-out collar 3, outer ring set 4 all can be made by stainless steel or other metal material, and sealing sword ring 5 can be by elasticity, and the material of acid and alkali-resistance for example teflon make.
The utility model universal joint, sealing sword ring 5 and outer ring set 4 constitute seal assembly, and sword ring 5 has elasticity, and acid and alkali-resistance, favorable sealing property, and outer ring set 4 can keep sword ring 5 stressed indeformable, reaches withstand voltage, anticorrosive, the usefulness that sealing is good, in addition, tapped locking sword ring 2 is formed positioning component, locking when the two is stressed with being with externally threaded stainless steel capillary 6, by the threaded engagement firm position, usually at 500 kilograms/cm
2Can not loose shift under the pressure.Operation is very easy when this universal joint used, stainless steel capillary 6 is inserted in the chromatographic column, compress outer ring set 4 successively, throw-out collar 3, locking sword ring 2 and hand-tight nut 1, up time turns hand-tight nut 1, screw thread is screwed in the chromatographic column column joint nut on it, then promotes locking sword ring 2 forward, throw-out collar 3, outer ring set 4 and sealing sword ring 5 realize that as the above-mentioned joint that makes sealing connects.During demolition, inhour turns hand-tight nut, makes each parts pressure relief, can unload whole universal joint.
By above-mentioned, use the utility model to connect with the different model chromatographic column, make the junction dead volume very little, favorable sealing property, and can load and unload long-term use repeatedly, wherein sealing sword ring 5 is consumable accessorys, use the replaceable spare part in the left and right sides 200 times, its operation is very simple and easy to do.
Claims (2)
1, a kind of liquid-phase chromatographic column universal joint, it comprises hand-tight nut, locking sword ring, parts such as sealing sword ring and stainless steel capillary is characterized in that sealing the sword ring 5 outer outer shroud covers 4 that are added with, and add throw-out collar 3 between locking sword ring 2 and the outer ring set 4, sealing sword ring 5, outer ring set 4, throw-out collar 3, locking sword ring 2 and hand-tight nut 1 are enclosed within successively on the stainless steel capillary 6 and constitute.
2, according to the described universal joint of claim 1, it is characterized in that locking the sword ring is a band internal thread opening sword ring, and stainless steel capillary has external thread, does positioning and locking by threaded engagement, can prevent to lock sword ring loose shift effectively.
