Description
Technical field
The utility model is related to chromatographic isolation technical field of analytical instruments, and in particular to a kind of ceramic liquid phase suction strainer head.
Background technology
When we carry out liquid-phase chromatographic analysis, suction strainer head is put into liquid storage bottle by we by needing, and passes through high-pressure pump
Pump out detection liquid to be tested and analyzed, made using stainless steel as existing suction strainer is first, on the one hand existing stainless steel suction
Filter volume is larger, when liquid is less in liquid storage bottle, can not often be drawn, and causes detection liquid utilization rate is not high to lack
Point, and traditional suction strainer head intracavity space is larger, easy air entrapment, and air enters liquid phase systems, and easily the pump housing is caused
Damage, block chromatographic column, and also easily cause the inaccurate of detection, existing suction strainer head is needed later using a period of time in addition
It is cleaned by ultrasonic for a long time, waste of manpower and time.
Utility model content
(1) technical problem to be solved
In order to overcome prior art not enough, it is proposed that a kind of ceramic liquid phase suction strainer head, it can improve the use of detection liquid
Rate, while the ultrafiltration cotton being convenient for changing is provided with, it is easy to clean.
(2) technical scheme
The utility model is achieved through the following technical solutions：The utility model proposes a kind of ceramic liquid phase suction strainer head, bag
Include connector and filter sheath, the connector bottom, which is provided with, to be provided with about one in the middle part of a connection boss, connector and pass through
Logical through hole and the connecting tube connected with through hole is provided with the top of connector, the filter sheath is by being arranged on portion
Inner groovy is with being connected boss threaded connection, and the bottom of filter sheath is provided with the pod apertures connected with inner groovy and in pod apertures
It is provided with check valve, the inner groovy and is provided with ultrafiltration cotton.
Further, the connector and filter sheath are formed using ceramics are made.
Further, highly it is no more than 6mm for installing the pod apertures of check valve.
(3) beneficial effect
The utility model has the advantages that relative to prior art：
A kind of ceramic liquid phase suction strainer head that the utility model is mentioned, it uses ceramics made, adds weight, is easy to whole
Suction strainer head sinks, while for traditional stainless steel suction strainer head, the suction strainer head of the structure greatly reduces height, extension
Detection liquid use time so that liquid utilization rate is greatly improved in liquid storage bottle, and the ceramic liquid phase suction strainer head internal cavities of this kind
Small, inside is not easy air entrapment, improves pump housing service life, is additionally provided with the ultrafiltration cotton that can be changed, without to filtering
Head is cleaned by ultrasonic.

Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain
The utility model, is not used to limit the utility model.
A kind of ceramic liquid phase suction strainer head as shown in Figure 1, including connector 1 and filter sheath 2, the bottom of connector 1
A connection boss 11 is provided with, the middle part of connector 1 is provided with the through hole 12 of a up/down perforation and set at the top of connector 1
There is the connecting tube 13 connected with through hole 12, the filter sheath 2 is by being arranged on the inner groovy 21 in portion with being connected the spiral shell of boss 11
Line is connected, and the bottom of filter sheath 2 is provided with the pod apertures connected with inner groovy 21 and check valve 22 is provided with pod apertures,
Ultrafiltration cotton 3 is provided with the inner groovy 21.
Wherein, the connector 1 and filter sheath 2 are formed using ceramics are made；Water conservancy diversion for installing check valve 22
Hole is highly no more than 6mm, can greatly improve the utilization rate of detection liquid.
A kind of ceramic liquid phase suction strainer head that the utility model is mentioned, ultrafiltration cotton 3 is put into filtering when specifically used by it
In inner groovy 21 on set 2, inner groovy 21 is then threadedly coupled fixation, connector 1 with the connection boss 11 of the bottom of connector 1
The connecting tube 13 at top is connected with liquid phase suction strainer pipe, during work, and the ceramic liquid phase suction strainer head is put into liquid storage bottle, is opened and is set
In the pump housing of liquid phase suction strainer pipe end, the detection liquid in liquid storage bottle by the check valve 22 in the pod apertures of filter sheath 2,
And inner groovy 21 is entered to by ultrafiltration cotton 3, and be sucked out by the through hole 12 in connector 1, check valve 22 can make
It must detect that liquid is unidirectional by being absorbed water, the utilization rate of detection liquid can be improved, it is simple in construction, it is easy to operate.
It is worth mentioning, when using after a period of time, can be changed ultrafiltration cotton 3 by outwarding winding filter sheath 2,
Change convenient, without being cleaned by ultrasonic.
Embodiment described above is only that preferred embodiment of the present utility model is described, not to this practicality
New spirit and scope are defined.On the premise of the utility model design concept is not departed from, this area ordinary person couple
The all variations and modifications that the technical solution of the utility model is made, all should drop into protection domain of the present utility model, this reality
With new claimed technology contents, all record in detail in the claims.
