Description
Technical field
The utility model is related to a kind of high-pressure pump, especially it is a kind of it is simple in structure, versatility is good and can reduce cost and subtract
Few dead volume with the integrated high-pressure pump of vent valve.
Background technology
Vent valve and high-pressure pump are the critical pieces in the equipment such as high performance liquid chromatograph.The effect of vent valve is discharge
High pressure pump head bubble, Rapid replacement mobile phase avoid entering high-pressure pump because of the bubble generated when working or replace mobile phase
And cause it that can not work normally；The effect of high-pressure pump is transport flow phase.Vent valve in existing high performance liquid chromatograph and
High-pressure pump is all two components of split, needs to be connected with pipeline between the two, not only causes waste of material, increases cost, and
And can increase the risk of connector position leakage, reliability reduces, while dead volume can be caused excessive, when extending mobile phase replacement
Between and gradient is caused to postpone.
The content of the invention
The utility model is to solve the above-mentioned technical problem present in the prior art, is provided a kind of simple in structure, logical
It is good with property and can reduce cost and reduce dead volume with the integrated high-pressure pump of vent valve.
The technical solution of the utility model is：A kind of and integrated high-pressure pump of vent valve, has pump head, in pump head
Equipped with fluid path, liquid-inlet and liquid outlet are connected to respectively with fluid path both ends, on pump head be equipped with it is vertical with fluid path communicate and
Front end is the hole of frustum, and with hole screw thread and being sealedly connected with valve body, the valve body front end is matched with hole front end taper, after valve body
It holds and connects with the hand button being placed in outside pump head, bleed passage is equipped in valve body and hand button.
The utility model is the device that vent valve and high-pressure pump are integrated, you can it saves material, reduce cost, and can
Avoided the leakage risk present in Multi-connecting head, good reliability, while dead volume can be reduced, shorten mobile phase replacing construction and
Gradient lag time.
Description of the drawings：
Fig. 1 is the structure diagram of the utility model embodiment.
Fig. 2 is the A-A views of Fig. 1.
Specific embodiment：
Below in conjunction with description of the drawings specific embodiment of the present utility model.As shown in Figure 1：Have same as the prior art
Pump head 1, fluid path 2 is equipped in the pump head 1, liquid-inlet 3 and liquid outlet 4 are connected to respectively with 2 both ends of fluid path, with existing skill
Art is threaded with valve except that equipped with the hole 5 communicated and front end is frustum vertical with fluid path 2 on pump head 1 with hole 5
Body 6 is provided with gasket 9 between valve body 6 and hole 5,6 front end of valve body is matched with 5 front end taper of hole, and 6 rear end of valve body is with being placed in pump
Hand button 7 outside first 1 connects, and bleed passage 8 is equipped in valve body 6 and hand button 7.
The course of work：
In use, liquid-inlet 3 and liquid outlet 4 are connected respectively with mobile phase pipeline, mobile phase flows through fluid path 2.Work
When making, can precession hand button 7,6 front end of valve body and 5 front end taper sealing of hole, while prevent mobile phase at hole 5 by gasket 9
Outflow；When needing to be vented or replacing mobile phase, hand button 7 can be screwed out, 6 front end of valve body is separated with 5 front end of hole, the bubble in fluid path 2
Or mobile phase can be flowed out by the bleed passage 8 in valve body 6 and hand button 7, can also directly be extracted with syringe, can accelerate to flow
The displacement of phase and discharge bubble.
