3rd, the special design of bottleneck is gathered, has accomplished that sampling process is fully sealed.
Brief description of the drawings
Fig. 1 is the structural representation of the present embodiment.
Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
One kind of the present invention exempts from purging from the emptying liquid closed sampler of self-closing, as shown in figure 1, including the He of triple valve one
Triple valve two.
The input of triple valve one is connected with semi-automatic double self-closing joints that surge by flowline, for accessing sampling bottle
Oil inlet, and flowline also on be provided with pressure gauge；The output end one of triple valve one is linked into master by a three-way pipe
On pipeline or bye-pass.
The output end two of triple valve one is connected to the second output end of triple valve two, and the input 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 blast 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 joint that surges, semi-automatic double use hard tube between self-closing pneumatic joint and sampling bottle
Connection, then be easy to not dock）；After the first output end access active carbon filter of triple valve two outside communication chamber.
Linked switch is provided with triple valve one and triple valve two.
Explanation is embodied：
First, open the stainless steel switch valve of main line and wait 2 minutes, allow oil product to progress into gathering line, so as to
So that exuberant oil product in pipeline.Then, the inlet of sampling bottle is connected with semi-automatic double self-closing joints that surge, by sampling bottle
Exhaust outlet connects with semi-automatic double self-closing pneumatic joints.It is then turned on linked switch and gets to passage one（I.e. triple valve one is defeated
Enter end to connect with output end one, the input of triple valve two and the connection of the first output end）, so as to which oil product is entered by triple valve one
Into closed sampling bottle, high pressure is formed in sampling bottle, the air in sampling bottle is pressed into activated carbon filtering from triple valve two
In device, 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 passage two（That is triple valve
One input connects with output end two, the input of triple valve two and the connection of the second output end）, now, in sampling bottle -- three
Port valve one -- triple valve two -- forms a closed loop between sampling bottle, the oil product remained in flowline can be in the work of gravity
It is flowed under in sampling bottle, and the air in sampling bottle will certainly be pressed into two threeway ball screw threads by pressure increase in sampling bottle
In connecting tube between valve, and further enter in flowline, so, the air and being extruded enough is helped and added
Oil product in fast flowline is discharged into sampling bottle.
Finally, wait 1 minute or so, treat that no liquid flows out in flowline, disconnect semi-automatic double self-closing joints that surge successively
With semi-automatic double self-closing joints that surge, the stainless steel switch valve of main line is closed, samples and completes.
Wherein, surge joint and pneumatic joint using double self-styled snap joints, can cause liquid medium collection and
Shut-off avoids switch valve to the liquid residue of collecting bottle on a point；When the design of interlocked valve and pipeline makes collection not
Stay remnants, and whole sealing sampling；Sampling bottle can use wealthy mouth sampling bottle or closing in sampling bottle etc..
The present invention 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, could be really
Solve the problems, such as liquid residue, so we solve this problem using double self-closing snap joints, exempt the cumbersome of blow device
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, so I
Gas exhaust piping is returned into gathering line initiating terminal, and sampling pipe valve is selected into triple valve with air bleeding valve, and between them
Associated collaborative, devises in a kind of sampling process that the collaboration of two steps is operation associated, and the first step is sampling, is sampled in sampling bottle to half
When, by cooperateing with association switch, change pipe passage form, the remaining oil product in pipeline is also fallen into sampling bottle, emptying is remaining
Oil product.
3rd, in sampling process, ensure that whole closed, it is therefore prevented that toxic and harmful gas or volatile organic matter（VOCs things
Material）Volatilization pollution.
This specific embodiment is only explanation of the invention, and it is not limitation of the present invention, people in the art
Member can make the modification of no creative contribution to the present embodiment as needed after this specification is read, but as long as at this
