Abstract
The utility model relates to a natural gas sampling device, which comprises the following components: a valve body, but be provided with the case of free rotation in the valve body the tee bend has been seted up in the case, the tee bend includes case admit air way, case pressure release way and case sample way offer on the valve body with case admit air valve body that way, case pressure release way and case sample way correspond respectively admit air way, valve body pressure release way and valve body sample way, outer port department has installed the relief valve on valve body pressure release way, port department is through connect nipple joint and connector to link to each other soon the valve body admits air the way outside, the port is located to feed through outside the way is taken a sample to the valve body has the sampling tube. Because carry out above -mentioned scheme, this application is through setting up the relief valve for can safe pressure release when sampling bag internal pressure is too high, guarantee that the sampling bag does not burst, eliminated because of the potential safety hazard that the sampling bag bursts and causes, avoid appearing the incident. This application simple structure, the single sample work that can accomplish the natural gas when using, it is efficient to take a sample.
Description
Technical field
The utility model relates to a kind of sampler, particularly relates to the rock gas sampler of pressure in a kind of controlled sampling bag processed.
Background technology
Rock gas is a kind of multi-component mixed gaseous fossil fuel, because it has the advantages such as unit calorific value is high, exhaust pollution is little, supply is reliable, price is low, world's energy market obtains large-scale application rapidly.But rock gas is also a kind of inflammable gas, for guaranteeing the security of rock gas in conveying, use procedure, must guarantee that the technical parameters such as the calorific value of rock gas, sulfur content, water dew point meet national standard.Gas transmission management unit ensures the commercial quality of rock gas, regularly must carry out sample examination to rock gas, in time grasp gas component situation, then adjusts manufacturing parameter in time according to makings result of laboratory test, guarantees that rock gas commodity meet country and industry standard.
Current domestic main use aluminum-plastic composite membrane gas sampling bag carries out rock gas sampling, sampling bag bearing capacity is low, mainly control the aperture sampling of needle valve by artificial experience during sampling, sampling pressure is wayward, sampling bag is easily caused to build the pressure explosion, cause rock gas loss containing poisonous and harmful element in atmosphere, the events such as easy generation personnel are poisoning, fire explosion event.
Summary of the invention
It is simple that the purpose of this utility model is to propose a kind of structure, the rock gas sampler of pressure in controlled sampling bag processed.
The purpose of this utility model is achieved in that rock gas sampler comprises valve body, spool free to rotate is provided with in described valve body, threeway is offered in described spool, described threeway comprises spool air inlet path, spool pressure release road and spool sampling road, described valve body offers and spool air inlet path, the valve body air inlet path of spool pressure release road and spool sampling road difference correspondence, valve body pressure release road and valve body sampling road, on valve body pressure release road, external port place is equiped with blowdown valve, be connected with connector by connecing pipe nipple soon at valve body air inlet path external port place, in valve body sampling, external port place, road is communicated with stopple coupon.
Owing to carrying out such scheme, the application, can safety relief when making sampling bag internal pressure too high by arranging blowdown valve, ensures that sampling bag does not burst, and eliminates because sampling bag bursts the potential safety hazard caused, avoids occurring security incident.The application's structure is simple, and the single sampling work that can complete rock gas in use, sampling efficiency is high.
Accompanying drawing illustrates: the technical solution of the utility model is provided by following drawings and Examples:
Fig. 1 is rock gas sampler structural representation.
Legend: 1, sampling pressure table, 2, valve body, 3, boost gauge, 4, air inlet branch road, 5, valve body air inlet path, 6, connect pipe nipple soon, 7, connector, 8, spool air inlet path, 9, blowdown valve, 10, valve body pressure release road, 11, spool pressure release road, 12, spool sampling road, 13, valve body sampling road, 14, stopple coupon, 15, sampling slip, 16, spool.
Embodiment: the utility model by the restriction of following embodiment, can not determine concrete embodiment according to the technical solution of the utility model and actual conditions.
Embodiment: as shown in Figure 1, rock gas sampler comprises valve body 2, spool 16 free to rotate is provided with in described valve body 2, threeway is offered in described spool 16, described threeway comprises spool air inlet path 8, spool pressure release road 11 and spool sampling road 13, described valve body 2 offers sample road 13 with spool air inlet path 8, spool pressure release road 11 and spool and distinguish corresponding valve body air inlet path 5, valve body pressure release road 10 and valve body and sample road 13.On valve body pressure release road 10, external port place is equiped with blowdown valve, and be connected with connector 7 by connecing pipe nipple 6 soon at valve body air inlet path 5 external port place, described connector 7 is in order to be connected with the sample tap on natural gas line.In valve body sampling, external port place, road 13 is communicated with stopple coupon 14.
Described valve body air inlet path 5 place offers a branch road, and this branch road is air inlet branch road 4, and in air inlet branch road external port, place is equiped with boost gauge 3, in order to observe air inlet pressure force value.Described air inlet branch road 4 also can as air inlet path for subsequent use, when valve body air inlet path 8 block or damage cannot use time, can be communicated with connecing soon pipe nipple 6 with air inlet branch road 4, carrying out air inlet.
Described valve body sampling road 13 place offers a branch road, and this branch road is sampling slip 15, and in sampling slip external port, place is equiped with sampling pressure table 1, in order to observe the force value in sampling bag.Described sampling slip 15 also can as sampling road for subsequent use, when valve body sampling road 13 block or damage cannot use time, or when needing repeatedly to sample, another stopple coupon 14 can be communicated with at sampling slip 15 place and sample.
During use, connector 7 is connected with the sample tap on natural gas line, stopple coupon 14 is communicated with sampling bag.Turn spool 16 subsequently, make spool air inlet path 8, spool pressure release road 11 and spool sampling road 13 sample road 13 one_to_one corresponding conducting with valve body air inlet path 5, valve body pressure release road 10 and valve body, can ventilate in sampling bag.After ventilation certain hour, be pressure in Observable sampling bag by sampling pressure table 1, thus determine whether stop sampling.If operating personnel do not observe pressure in sampling bag in time, after in sampling bag, pressure reaches extreme value, the automatic conducting of blowdown valve 9 meeting, automatically discharges rock gas unnecessary in sampling bag, avoids sampling bag to burst.Described blowdown valve 9 is prior art, and its concrete structure is not described in detail at this.
Above technical characteristic constitutes most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease inessential technical characteristic according to actual needs.
