Abstract
The utility model provides a kind of liquid-inlet valve, it is mainly used for chromatographic column, including nozzle, valve seat, hollow cylinder, liquid-in pipe, cleaning pipe etc., glue spraying pipe and nozzle is pulled to move downwardly together or upwards by cylinder to realize the opening and closing of valve, so as to complete the cleaning of the filling or chromatographic column and valve of chromatograph packing material in itself.The utility model is simple and reliable for structure, and volume compact is compact, substantially reduces the labor intensity of staff, improves work efficiency.
Description
Technical field
A kind of liquid-inlet valve is the utility model is related to, is mainly used on chromatographic column, belongs to liquid chromatogram field.
Background technology
Advantage of the chromatographic technique in separation field is it is well known that can be used for efficiently separating from complex mixture
Go out target product, the impurity in removal object, the purification of final product or displacement of product solution etc., there is high separating efficiency
The characteristics of, the product of temperature-sensitive or easy in inactivation, such as protein, polysaccharide and polypeptide can be separated under conditions of condition is relatively mild.
Chromatographic column is the key for realizing chromatography, chromatographic column generally by column casing, the top dispenser of adjustment height, bottom dispenser and
Granulated filler for being used to parse between upper and lower distributor and column casing etc. forms.Top dispenser is equipped with mobile phase entrance
Valve, bottom dispenser are equipped with mobile phase outlet valve.General chromatographic column liquid-inlet valve usually carries the glue spraying function of automatic Loading
And automatic cleaning function.And the liquid-inlet valve of the prior art is automatically controlled usually with two cylinders（13）Add two connecting rods（12）With one
A little other component compositions, complicated, volume greatly, easily break down（As shown in Figure 5）.The present invention uses a middle air
Cylinder, glue spraying pipe are entered in column by cylinder piston centre bore, realize glue spraying and cleaning function.Total is simple and reliable, volume
It is compact compact.
The content of the invention
It is an object of the invention to provide a kind of liquid-inlet valve, can be used for the filler filling and cleaning of chromatographic column, to solve
Prior art construction is complicated, volume is big, easy the shortcomings of breaking down.Concrete technical scheme is as follows：
A kind of liquid-inlet valve 1, including nozzle 3, valve seat 7, hollow cylinder 5；The outside of valve seat 7 is equipped with liquid-in pipe 8 and cleaning pipe 6,
Hollow cylinder 5 is installed on the top of valve seat 7, and hollow cylinder 5 includes cylinder body 11, piston 10, cylinder head 14, glue spraying pipe 4 and bolt
9, glue spraying pipe 4 is fixed on 10 upper end of piston, and through hollow cylinder 5 and valve seat 7, nozzle 3 is installed on the lower end of glue spraying pipe 4.Cylinder
A closed upper cavity 15 is formed between lid 14, cylinder body 11 and piston 10, is formed between cylinder body 11, piston 10 and glue spraying pipe 4
One closed lower chamber 16.
Preferably 11 top and bottom of cylinder body, piston 10 and 14 center of cylinder head are equipped with circular hole, and glue spraying pipe 4 passes through circle
Hole passes through cylinder head 14, piston 10 and cylinder body 11.
It is driving device that nozzle 3, which can equably spray homogenate filler or cleaning solution, hollow cylinder 5, and liquid-in pipe 8 is color
Mobile phase entrance used in spectrum, cleaning pipe 6 are filter washing water inlets, and homogenate filler enters from glue spraying pipe 4 when filling is expected, during valve seat 7 is
Air cylinder 5, liquid-in pipe 8, the carrier of cleaning pipe 6.
It is an advantage of the invention that：Total is simple and reliable, and volume compact is compact, can both realize and equably load chromatography
Filler, improves column effect, and can clean chromatographic column and liquid-inlet valve automatically in itself, easy to operate, greatly reduces staff's
Labor intensity, improves work efficiency.

Embodiment：
With reference to attached drawing, the invention will be further described.
When chromatographic column fills column, upper chamber of air cylinder body 15 is inflated, and air pressure promotes piston 10 to pull glue spraying pipe 4 and nozzle 3 together
Move downward, nozzle 3 stretches out distributor（State as shown in Figure 2）, at this time, nozzle 3 is stretched into chromatographic column, glue spraying pipe 4 and chromatography
Column connects.Homogenate is pumped into from glue spraying pipe 4 to be uniformly sprayed onto in column by nozzle 3, gradually completes dress column.
After chromatographic column homogenate filling, lower chamber of air cylinder body 16 is inflated, and air pressure promotes piston 10 to pull glue spraying pipe 4 and spray
First 3 move upwardly together, in 3 retraction distributor of nozzle（State as shown in Figure 1）, at this time the passage of glue spraying pipe 4 and chromatographic column close
Close.Glue spraying pipe 4 and cleaning pipe 6 communicate, and cleaning solution is pumped into being cleaned inside liquid-inlet valve 1 from cleaning pipe 6, and waste liquid is from glue spraying pipe
4 discharges；Communicated in liquid-in pipe 8 and column, mobile phase is pumped into from liquid-in pipe 8, so as to carry out chromatographic isolation.
