The case where line connection, it is bad to have an air-tightness, gas leakage.
(application number: 201520034011.1) disclosing a kind of adjustable vapour lock device of gas chromatograph to Chinese patent, uses
One section of elastic quartz capillary tube is sealed in the male inner hole with sheath mother of sheath with gasket using one section of elastic quartz capillary tube
In, gasket is pressed in the interior wire hole of sheath mother at the middle part of capillary by the male outer silk of sheath；Sheath is male female outer with sheath
Type is hexahedron, and the other end has the outer silk for taking back cutter groove, and inner hole port has with bell-mouthed counterbore；Identical vapour lock just intercepts
The capillary of equal length is packed into, different vapour locks, and the capillary for just intercepting different length is packed into.This device there are the shortcomings that
It is quartz capillary easy fracture in use, process is cumbersome, is not easy to control.
Summary of the invention
The purpose of this utility model is that in view of the problems of the existing technology, provide a kind of gas chromatograph can regulating the qi flowing in the channels
Device is hindered, needle is adjusted using motor, can effectively solve the problems such as manually adjusting bring time-consuming, effort, poor accuracy.
A kind of in order to achieve the above purposes, the technical solution adopted by the utility model is: adjustable vapour lock device of gas chromatograph,
Including gas outlet, quartz pushrod, air inlet, shell, needle, described shell one end is equipped with air inlet, is equipped with needle in housing hollow,
The shell other end is connected to the motor, and shell upper end is equipped with gas outlet；Motor casing is equipped with outside motor；Needle outer end and motor connect
It connects.
The specific process for adjusting air inflow are as follows: gas enters from left end air inlet, and needle, setting are equipped in housing hollow
The revolving speed of good motor is operated by motor and needle is driven to move left and right come regulating gas supply.
Preferably, the motor is linear motor.
It preferably, is to be threadedly coupled between the needle and motor.Motor, which is rotated and is threadedly engaged, drives needle mobile next
The accurate air inflow for adjusting gas chromatograph.
Preferably, it is to be detachably connected between the motor housing and shell, the first sealing is equipped in the groove of junction
Circle.
Preferably, the second sealing ring is equipped in the motor housing and the groove of needle junction.
By the way that sealing ring is arranged in motor housing and housing junction or shell and needle junction, vapour lock device is improved
Reliability improves the air-tightness of gas chromatograph.
Preferably, second sealing ring is equipped with twice, further increases the air-tightness of gas chromatograph.
Preferably, the shell is shaft-like Stainless Steel Shell.
Preferably, air inlet is the through-hole that diameter is 0.1mm.
Preferably, the overall diameter of quartz pushrod is 0.53mm, long 3cm.
Compared with prior art, the utility model has the beneficial effects that 1, be connected with needle by the way that a motor is arranged, can be with
It realizes automation control gas flow, avoids manually operated inconvenience and error problem；2 motor housings and housing junction, outside
Shell and needle junction are equipped with sealing ring, to guarantee the air-tightness of whole device.
