Description
Technical field
The present invention relates to fluid sampling device more particularly to a kind of fluid sampling devices and use in vertical bank tank
Method.
Background technique
At home and abroad in trade, the petrochemicals such as crude oil, gasoline, crude glycerine, fluid chemical raw material, base oil, greatly
Method is all counted weight using vertical bank tank, this is owned by France in static weighing, and measuring principle is weight=volume × density, because metering is theoretical and
Standard method is mature, so the metering of vertical bank tank is the conventional metered dose mode of liquid product, it is still wide in trade contacts week at present
General use.
In vertical the filled liquid of bank tank because liquid quality itself and weight component are unevenly distributed, it is easy to cause density point
Layer, that is, in vertical bank tank, supernatant liquid density is relatively small, bottom deposit the biggish liquid of density, and in this way
Liquid distribution generally will not be linearly distributed with liquid level.For this class I liquid I, when vertical bank tank calculates the weight, sampling
Calculating density work is particularly important, will be vertical at present generally according to GB/T 4756-1998 petroleum liquid hand sample method
Bank tank is divided into the sampling of three positions in upper, middle and lower, general top be 1/6th of total liquid depth apart from liquid level, middle part takes
Sample position is the centre (the namely half of liquid level) just in liquid level and bottom surface distance, bottom sample position be apart from bottom surface away from
From 1/6th plane for liquid depth.It in actual operation can be according to the physical property of vertical bank tank liquid, volume, vertical
Formula bank tankage size etc. increases sample point, but also due to some defects of sampler, cause samples taken real
The oil density of entire bank tank is represented, so sampler can directly affect the metering of vertical bank tank.
Sampling generally uses hand sample in current vertical bank tank, and there are mainly three types of types at present for hand sample cutter: top
Be open sampler, bottom opening sampler and holostrome sampler.Currently used is water-finder, sampler bottom have one into
Sample mouth is clogged before sampling with plug, and plug connects metallic rod, and metallic rod upper end passes through among the top of the sampler, and connects length
Rope.When sampler dive is to sampling liquid level, bottom sample introduction piston is firmly pulled open by long rope, fluid sample passes through bottom sample introduction
Mouth enters in sampler, after the completion of sampling, unclamps long rope, piston closes injection port under the effect of gravity.This type sampler
Disadvantage is sampler before decentralization reaches sampling liquid level, it is possible to because sampler external and internal pressure is different, lead to injection port
Piston opens sample introduction in advance, and the sample collected is without representativeness.The bottom of top opening sampler be it is closed, top has one
Round mouth, and clogged with piston, piston equally connects long rope, and when sampler reaches specified sampling liquid level, quick drawstring is opened and lived
Plug, liquid just enter in sampler from injection port.The sampler of this type due to during upper mention lid it is in the open state,
When drawing high upwards, liquid is easy to swap due to effect of inertia with sampler outside liquid in sampler, in this way from vertical
The liquid of bank pot bottom sampling is all exchanged substantially, loses representativeness.
Chinese patent literature CN 201310036265.2 discloses a kind of fluid sampling device, including liquid storage device, feed liquor list
To valve, inlet automatic piston, go out liquid one-way cock, liquid outlet automatic piston, tubaeform flow-guiding mouth, round inlet filtering
Net, conical liquid outlet filter screen, conical protective cover, air bag；Wherein, it is provided with liquid outlet on liquid storage device upper surface, out liquid
Mouth has been sequentially arranged above liquid outlet automatic piston, has gone out liquid one-way cock, conical protective cover, is installed with cone in protective cover
Liquid outlet filter screen；Liquid storage device lower end is disposed with inlet one-way cock, inlet automatic piston, annular inlet filtering
Net is provided with air bag between inlet automatic piston and inlet one-way cock；Among annular inlet filter screen below circular hole
One tubaeform flow-guiding mouth is installed.The method is suitable for the fields such as liquid sample collecting analysis.Although the present invention can take liquid
Body sample, but use liquid from sampler bottom sample introduction, by between inlet automatic piston and inlet one-way cock
Air bag is realized, cannot accurately be got the fluid sample of different depth, is unsatisfactory for the requirement of liquid sampling in vertical bank tank, simultaneously should
Sampler goes out sample from sampler top using liquid, needs human assistance handstand sampler that could complete, if taken liquid
To be perishable, volatile, exist to operator and endanger.
Chinese patent literature CN 201310317275.3 discloses a kind of portable fluid sampler and its sampling side
Method, it includes probe tube, and top ball valve and bottom end ball valve, the core shaft connection of bottom end ball valve is respectively set in the both ends of probe tube
The middle part of ball valve handle in bottom end is provided with two rows of opposite wire rope handling guide rails, each row's wire rope handling guide rail packet on tube body lateral wall
Several wire rope handling annulus separately are included, wire rope handling annulus arranges the wire rope handling guide rail for forming straight line shape on tube length direction
And it is parallel with tube body, the wirerope beginning is connected to one end of bottom end ball valve handle, and end sequentially passes through two rows of wire rope handlings and leads
The wire rope handling annulus of rail is connected to the other end of bottom end ball valve handle.It is taken although the sampler is suitable for different layers position fluid sample
Sample both may be implemented full liquid level liquid sample, the sampling of the fluid sample of fixing layer position also may be implemented, but taken with this
Sample device extracts vertical bank pot liquid, cannot effectively determine depth selection.The sampler mainly in large trough or tank car not
Homogeneous liquid sampling.
