Pollute this acquisition sample.
Utility model content
The purpose of this utility model is to provide one kind and exempts from purging from the emptying liquid closed sampler of self-closing, has sampling
Mouthful, sampling bottle is self-closing and pipeline gas is from air emptying function, not only environmentally friendly without falling sample in lower sub-sampling, but also can guarantee each sample
Product are not contaminated.
The above-mentioned technical purpose of the utility model technical scheme is that：
One kind exempts from purging from the emptying liquid closed sampler of self-closing, including triple valve one and triple valve two；The threeway
The input terminal of valve one is connected with semi-automatic double self-closing connectors that surge, and output terminal one is connect with oil pipeline, output terminal two and threeway
The second output terminal connection of valve two, the input terminal of triple valve two are connected with semi-automatic double self-closing pneumatic joints, and the of triple valve two
One output terminal is connected with filter.
Further, the connector that surges for semi-automatic double self-closing connectors that surge, hold one's breath certainly for semi-automatic pair by pneumatic joint
Dynamic connector.
Further, it is provided with linked switch on triple valve one and triple valve two.
Further, it is connected between semi-automatic double self-closing pneumatic joints and the input terminal of triple valve two by exhaust pipe, and
And flange-connection stainless steel metal flexible pipe is equipped with close to one end of semi-automatic double self-closing pneumatic joints in exhaust pipe.
Further, the filter is active carbon filter.
Further, it is provided with pressure gauge between triple valve one and semi-automatic double self-closing connectors that surge.
In conclusion the utility model has the advantages that：
1st, using double self-sealing joints, and sampling bottle lid is transformed, solves the problems, such as residual liquid water clock and nothing
It needs to purge；
2nd, it solves the problems, such as that dead sample remains by valve member association and circuit design, accomplishes pipeline evacuation after acquisition, exempt
The pollution of falling sample and waste during next sampling；
3rd, the special design of bottleneck is acquired, has accomplished that sampling process is fully sealed.
Description of the drawings
Fig. 1 is the structure diagram of the present embodiment.
Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
One kind of the utility model exempts from purging from the emptying liquid closed sampler of self-closing, as shown in Figure 1, including triple valve
One and triple valve two.
The input terminal of triple valve one is connected with semi-automatic double self-closing connectors that surge by flowline, for accessing sampling bottle
Oil inlet, and flowline also on be provided with pressure gauge；The output terminal one of triple valve one is linked into master by a three-way pipe
On pipeline or bye-pass.
The output terminal two of triple valve one is connected to the second output terminal of triple valve two, and the input terminal of triple valve two passes through row
Tracheae is connected with semi-automatic double self-closing pneumatic joints, for accessing the exhaust outlet of sampling bottle, and in exhaust pipe close to semi-automatic
One end of double self-closing pneumatic joints is provided with one section of flange-connection stainless steel metal flexible pipe, facilitates semi-automatic double self-closing pneumatic joints and sampling bottle
Between connection（If semi-automatic double self-closing connector that surges semi-automatic double uses hard tube between self-closing pneumatic joint and sampling bottle
Connection, then be easy to not dock）；After the first output terminal access active carbon filter of triple valve two outside communication chamber.
Linked switch is provided on triple valve one and triple valve two.
Explanation is embodied：
First, it opens the stainless steel switch valve of main line and waits for 2 minutes, oil product is allowed to progress into gathering line,
So that exuberant oil product in pipeline.Then, the inlet of sampling bottle with semi-automatic double self-closing connectors that surge is connected, will sampled
The exhaust outlet of bottle is connected with semi-automatic double self-closing pneumatic joints.It is then turned on linked switch and gets to channel one（That is triple valve one
Input terminal connected with output terminal one, the input terminal of triple valve two and the first output terminal connection）, so as to which oil product passes through triple valve one
It enters in closed sampling bottle, high pressure is formed in sampling bottle, the air in sampling bottle is pressed into activated carbon from triple valve two
In filter, after filtering, the discharge of clean air is outdoor for the air with oil gas.
When the liquid in sampling bottle reaches the half of sampling bottle capacity, linked switch is reached into channel two（That is triple valve
One input terminal is connected with output terminal two, and the input terminal of triple valve two is connected with second output terminal）, at this point, in sampling bottle -- three
Port valve one -- triple valve two -- forms a closed circuit between sampling bottle, remaining oil product can be in the work of gravity in flowline
It is flowed into sampling bottle under, and the air in sampling bottle will certainly be pressed into two threeway ball screw threads by pressure increase in sampling bottle
It in connecting tube between valve, and further enters in flowline, so, the air being extruded can be helped and be added again
Oil product in fast flowline is discharged into sampling bottle.
Finally, it waits for 1 minute or so, treats that no liquid flows out in flowline, disconnect semi-automatic double self-closing connectors that surge successively
With semi-automatic double self-closing connectors that surge, the stainless steel switch valve of main line is closed, sampling is completed.
Wherein, surge connector and pneumatic joint using double self-styled quick couplings, can cause liquid medium acquisition and
On a point, the liquid for avoiding switch valve to collecting bottle remains for shutdown；When the design of interlocked valve and pipeline makes acquisition not
Stay remnants, and whole sealing sampling；Wealthy mouth sampling bottle or closing in sampling bottle etc. can be used in sampling bottle.
The utility model has the advantage that：
1st, the sample wall built-up residue problem of sampling bottle pipeline is arrived after solution switch valve, only cancels this section of pipeline, Cai Nengzhen
Positive solution liquid residue problem, so we solve the problems, such as this using double self-closing quick couplings, exempts blow device
Cumbersome flow and troublesome in poeration, and sampling bottle bottleneck is transformed.
2nd, the sample carryover issues before solution valve in pipeline, otherwise sampling is required to down sample every time, causes environmental pollution, institute
Gas exhaust piping is returned into gathering line initiating terminal, and sampling pipe valve is selected into triple valve, and at them with air bleeding valve with us
Between associated collaborative, devise in a kind of sampling process that the collaboration of two steps is operation associated, and the first step is sampling, sampling bottle sample to
During half, by cooperateing with association switch, change pipe passage form, the remaining oil product in pipeline is also fallen into sampling bottle, empty
Remaining oil product.
3rd, it in sampling process, ensure that whole closed, it is therefore prevented that toxic and harmful gas or volatile organic matter（VOCs objects
Material）Volatilization pollution.
This specific embodiment is only explanation to the utility model, is not the limitation to the utility model, ability
Field technique personnel can as needed make the present embodiment the modification of no creative contribution after this specification is read, but
As long as it is all protected in the right of the utility model by Patent Law.
