Abstract
The utility model discloses a kind of micro-positive pressure sampler booster pumps.It includes the shell that cylinder and cylinder head portions are fixedly mounted, and the telescopic rod of cylinder is extend into shell, bellows is provided in shell, telescopic rod connect with bellows and can pull bellows stretching motion in shell.After above-mentioned structure, the shell and shell being fixedly mounted due to cylinder head portions are closed to install the bellows pulled by telescopic rod, thus to make medium enter sampling container by the bellows of booster pump, realize function of increasing pressure, its smart structural design is reasonable, reasonable structure design is so that good leak tightness, Reliability of Microprocessor is high, in addition, because it is completely closed and without sealing material, the security risk for reducing the leakage brought by the physical property corrosion sealing material of medium, meets the use condition of the poisonous and harmful medium of current petrochemical enterprise.
Description
Technical field
The utility model relates to a kind of auxiliary equipment of micro-positive pressure sampler, specifically a kind of micro-positive pressure sampler is used
Booster pump.
Background technique
In the prior art, conventional sampler is usually all to pressurization in pipeline so that in pipeline there is pressure can lead to
Excess pressure is sampled operation, however, for sour gas (severe toxicity) gas-sample analysis in some petrochemical industry, chemical field,
Because live loine pressure is too low, it is also not allow for biggish pressure, therefore the media collapse that will cannot be acquired well is to taking
In sample container, and for such gas sample, micro-positive pressure can be realized using auxiliary device, however for micro-positive pressure
Power device usually will appear it is poorly sealed cause leak (toxic gas) and because medium physical property corrosion sealing material bring
Leakage security risk.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of designs of structure simple, use reliability, good airproof performance
And it is avoided that corrosion brings the micro-positive pressure sampler booster pump of leakage problem.
In order to solve the above-mentioned technical problem, the micro-positive pressure sampler booster pump of the utility model, including cylinder and gas
The shell that cylinder end portion is fixedly mounted, the telescopic rod of cylinder are extend into shell, and bellows, telescopic rod and ripple are provided in shell
Pipe connects and can pull bellows stretching motion in shell.
The bellows is 316 corrugated stainless steel tubings.
The control terminal of the cylinder is connected with the linked switch that can control cylinder operation.
The linked switch is that can pass through the gas source switching valve of nitrogen.
After above-mentioned structure, the closed installation of the shell and shell being fixedly mounted due to cylinder head portions is by telescopic rod
The bellows of pulling realizes function of increasing pressure thus to make medium enter sampling container by the bellows of booster pump,
Smart structural design is reasonable, and reasonable structure designs so that good leak tightness, Reliability of Microprocessor is high, in addition, because its be completely closed and
There is no sealing material, reduces the security risk of the leakage brought by the physical property corrosion sealing material of medium, meet current stone
The use condition of the poisonous and harmful medium of oily chemical company.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model micro-positive pressure sampler booster pump.
Specific embodiment
With reference to the accompanying drawings and detailed description, the micro-positive pressure sampler of the utility model is made with booster pump further
It is described in detail.
As shown, the micro-positive pressure sampler booster pump of the utility model, including cylinder 1 and the fixed peace of cylinder head portions
The telescopic rod 3 of the shell 2 of dress, cylinder 1 is extend into shell 2, and bellows 4, the control terminal connection of cylinder 1 are provided in shell 2
There is the linked switch 5 that can control cylinder operation, can control the operation of cylinder, telescopic rod 3 and wave from there through linked switch 5
Line pipe 4 connects and can pull under the driving of cylinder bellows stretching motion in shell 2, and linked switch connects nitrogen gas
Source finally realizes and pulls bellows by the pull of linked switch control cylinder, to achieve the purpose that pressurization.
Further, described bellows 4 is 316 corrugated stainless steel tubings, and described linked switch 5 is that can pass through nitrogen
Gas source switching valve.
