Abstract
The utility model is related to one kind for dredging instrument pressure tappings blocking device online, including fluid line (1), threeway pressure pipeline (2), a valve (3), dredge valve (4) and transmitter (5), two pipelines of the wherein described threeway pressure pipeline (2) are connect with fluid line (1), transmitter (5) respectively, Article 3 pipeline is equipped with dredge valve (4), and the pipeline that the threeway pressure pipeline (2) connect with transmitter (5) is equipped with a valve (3).The present apparatus realizes transmitter pressure tappings and dredges online, more convenient simple compared with tradition dismounting transmitters sense pipeline dredging pressure tappings, saves the repair time, reduces the cost of overhaul.
Description
Technical field
The utility model category pressure pipe road technique field is blocked more particularly to one kind for dredging instrument pressure tappings online
Device.
Background technology
Easily there is pressure pipeline one in operational process in transmitter for measuring dirty gas/liquid pressure or differential pressure
The problem of pressure tappings block and are difficult to steady in a long-term, accurate measurement before secondary valve, what traditional pressure pipeline can not be dredged online lacks
Point, therefore for crucial test point, which is unfavorable for pole the safe and stable operation of unit.And existing popular automatic back blow
Device, there is also the higher unfavorable factors of energy consumption in addition to drawbacks described above.
In view of the foregoing, it is necessary to develop a kind of device of Quick dredging connecting pipe pressure tappings, so as to transmitter reality
Now long-term on-line checking, the parameters of association unit can not monitor in real time when not only can avoid because of transmitter pilot blockage,
Can also periodically online blowdown, prevent pressure tappings block.
Invention content
The technical problem to be solved by the utility model is to provide one kind for dredging instrument pressure tappings blocking device online,
By increasing dredge valve on pipeline, solve traditional blowdown apparatus and be unable to periodic cleaning pressure tappings, need to transmitter pipeline into
The shortcomings that row dismounting could carry out.
Technical solution adopted by the utility model to solve its technical problems is：One kind is provided to take for dredging instrument online
Mouth blocking device, including fluid line, threeway pressure pipeline, a valve, dredge valve and transmitter are pressed, wherein the threeway pressure
Two pipelines of pipeline are connect with fluid line, transmitter respectively, Article 3 pipeline is equipped with dredge valve, the threeway pressure pipe
The pipeline that road is connect with transmitter is equipped with a valve.
The further technical solution of the utility model is that the pipeline that the threeway pressure pipeline is connect with transmitter is equipped with
Two valves, described two valves centres are equipped with branch pipe(tube).
The further technical solution of the utility model is that the branch pipe(tube) is equipped with a valve a.
Advantageous effect
The advantages of the utility model, has：
1, the present apparatus realizes transmitter pressure tappings and dredges online, and pressure tappings are dredged with tradition dismounting transmitters sense pipeline
It compares, it is more convenient simple, the repair time is saved, the cost of overhaul is reduced；
2, the present apparatus realizes the function of periodically online blowdown；
3, device making is simple, of low cost, is easily achieved, and is suitable for other same categories of device.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
Fig. 2 is existing structure schematic diagram.
Specific implementation mode
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model instruction
Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
It please the appended claims limited range.
Embodiment 1
As shown in Figure 1, a kind of for dredging instrument pressure tappings blocking device, including fluid line 1, threeway pressure pipe online
The valve 3 of road No. 2, one times, dredge valve 4 and transmitter 5, wherein two pipelines of the threeway pressure pipeline 2 respectively with fluid line 1,
The connection of transmitter 5, Article 3 pipeline are equipped with dredge valve 4, are set on the pipeline that the threeway pressure pipeline 2 is connect with transmitter 5
Once valve 3.
A valve 3 there are two being set on the pipeline that the threeway pressure pipeline 2 is connect with transmitter 5, described two valves 3
Centre is equipped with branch pipe(tube) 6, and the branch pipe(tube) 6 is equipped with a valve a7.
In actual use, the dredge valve opening mounted on threeway pressure pipeline one end, the stolen goods being attached near pressure tappings
Object can be expelled directly out；If pressure tappings directly block, may be used the steel wire smaller than dredge valve bore carry out dredging online or
Steam-out (SO) purging dredging, directly closes dredge valve after dredging, need not dismount transmitter pressure pipeline can be at once extensive
Repetition measurement amount.When transmitter reaches blowing period, dredge valve can be directly opened periodically to pressure tappings blowdown, such transmitter
It measures pipeline not to be affected, is now applied to high pyrogene gas piping pressure pipeline, refined pressure vessel, Mixture Density Networks compression ring
Some equal pressure tappings are easy on blocked device on shape orifice plate pressure ring.
