Description
Technical field
The sampler of storage tank is the utility model is related to, particularly a kind of large-scale storage tank Stratified Sampling device, main application
In places such as oil, the oil-gas gathering and transportation station of chemical industry, storehouses, the liquid sample in storage tank is obtained.
Background technology
At present, the gathering station in petroleum and petrochemical sector, storehouse, for the liquid sample in chemical examination storage tank, it is most widely used that sampling
Bucket.Existing sample bucket is the cylinder barrel made of copper sheet, and bung is clogged with copper plug, with the band copper every one meter of knotting
The rope of silk ties down sample bucket, desired position is arrived under bucket, above puies forward rope handle plug opening, is sampled.Transfer sample bucket
Afterwards, plug is not opened or opened in advance, it is necessary to above carries sample bucket lid plug again again；It is big to sample the rope error of graduation,
The operation of rope makes sample position inaccurate in sampling, causes second order error again；After sampling, sampling bung is opening,
During upper carry, the liquid sample of other layers of position can be taken out together, pollution takes the liquid sample of layer position.Existing sample bucket sampling error
It is bigger, it is cumbersome and time consuming.
The content of the invention
The utility model provides a kind of large-scale storage tank Stratified Sampling device, when change is at present that storage tank samples using sample bucket
Layer position error and the big present situation of liquid sample error, the liquid sample of different layers position can be precisely taken out, ensure the precision of liquid sample, improve work
Make efficiency, provide accurate liquid all product for production analysis.
1st, this technology solution is up to above-mentioned purpose：A kind of large-scale storage tank Stratified Sampling device includes sampling pump and layering
Valve group is sampled, sampling pump is fixed near storage tank sample tap by support, and cycle sampling pipe connects with the top of pump barrel, the bottom of pump barrel
Portion is connected from Stratified Sampling valve group by connecting tube and connected by Stratified Sampling valve group with different sampling horizons.
Compared with prior art, significantly using effect of the present utility model is：The present apparatus uses depression bar pump as sampling pump,
It is fixed on by support near sample tap, makes cycle sampling pipe corresponding with sample tap, the liquid sample retained in sampling pump can be made,
Before taking new liquid sample, sampling pump is operated first the liquid sample that preceding sub-sampling is retained is put into storage tank sample tap, avoided waste and pollute
Environment.The present apparatus uses rubber piston, can prevent from producing electrostatic or metal sparking between metal pump barrel, ensure safety
Production.The pump barrel of the present apparatus is connected with connecting tube and Stratified Sampling valve group, and each sampling valve of Stratified Sampling valve group passes through suction
Sample pipe connects from the different sampling horizons set, as long as opening the sampling valve on different sampling horizons, just can precisely, rapidly take
Go out the liquid sample of this layer of position.It is swift to operate, conveniently, take liquid sample reliable, precisely.Not only effectively increase operating efficiency, Er Qiewei
Production provides accurately liquid sample data, has significant using effect and social benefit.
Brief description of the drawings
Fig. 1 is the front view of the utility model structure diagram.
Fig. 2 be in Fig. 1 A-A to structural representation.
Embodiment
The utility model is described in detail below in conjunction with accompanying drawing, not limits the scope of protection of the utility model.It is as described below to be only
Preferred embodiment of the present utility model, other use equivalence changes of the present utility model, all should belong to protection of the present utility model
Scope.
Referring to Fig. 1 and Fig. 2, a kind of large-scale storage tank Stratified Sampling device includes sampling pump and Stratified Sampling valve group 8, sampling pump
It is fixed on by support 11 near storage tank sample tap 9, cycle sampling pipe 5 connects with the top of pump barrel 4, and the bottom of pump barrel 4 passes through company
Adapter 2 is connected from Stratified Sampling valve group 8 and connected by Stratified Sampling valve group 8 with different sampling horizons.
The sampling pump is depression bar pump, including pump barrel 4, rubber piston 6, connecting rod 3 and handle 1, rubber piston 6 and connecting rod 3
Connect, in pump barrel 4, handle 1 is connected with the upper end of connecting rod 3, above cycle sampling pipe 5 and the top dead-centre of rubber piston 6
Pump barrel 4 connects.
The cycle sampling pipe 5 is that bend pipe, its mouth of pipe are corresponding with storage tank sample tap 9, can make to retain in sampling pump and surplus
Remaining liquid sample is flowed into storage tank sample tap 9.
The Stratified Sampling valve group 8 is at least provided with two sampling valves, and each sampling valve is by connecting short tube and connecting tube 2
Connection, each sampling valve connect further through suction tube 10 with the sampling horizon set.
Atmospheric valve 7 is also connected with the pipeline section of the connecting tube 2, the mouth of pipe of the atmospheric valve 7 is relative with storage tank sample tap 9
Should, liquid sample can be prevented to be deposited in pump barrel 4, again liquid sample can be made to back into storage tank.
The storage tank sample tap 9 is the original sample tap of storage tank or what is opened up on storage tank loophole ring flange 12 takes
Sample mouth.Because the aperture of storage tank loophole is big, sample tap is opened up on storage tank loophole ring flange 12, again by its envelope after sampling
Close, use and operate and be more convenient.
In use, only needing to open the sampling valve in the Stratified Sampling valve group 8 corresponding with sampling horizon, handle is pressed
1, drivening rod 3 makes rubber piston 6 pump, the liquid sample can such as oil, water in sampling horizon along sampling valve, connection
Short tube and connecting tube 2 enter in pump barrel 4, and the liquid sample that original retains is put into storage tank sample tap 9 by cycle sampling pipe 5, returns to storage
In tank.Dead liquid sample to be retained is drained, you can liquid sample is accessed in cycle sampling pipe 5.Sampling is finished, and atmospheric valve 7 is opened, made
Liquid sample in pump barrel 4 returns tank.
