Abstract
The utility model provides a vacuum pipeline liquid sampler comprising a vacuum pipeline, a valve 1, a valve 2, a valve 3 and a valve 4. It is characterized in that: the valve 1 is arranged in the vacuum pipeline; the valve 2 and the valve 3 are arranged on the vacuum pipeline at two ends of the valve 1; the other ends of the valve2 and the valve 3 are connected by a U-shaped tube; the valve 4 is connected with the middle part of the U-shaped tube; the other end of the valve 4 is the liquid sampling outlet; and when sampling, open the valve 2 and the valve 3, close the valve 1, make the U-shaped tube full of liquid, then close the valve 2 and the valve 3, open the valve 1, open the valve 4 at last, and then the liquid sample left in the U-shaped tube can be taken out. When adopting the utility model to sample, the intracavity of the vacuum pipeline and the sampling outlet can be completely isolated through operating the valve switch, so the vacuum degree in the vacuum pipeline cannot be influenced, and the sampling operation is simple and convenient.
Description
Technical field
The utility model relates to a kind of fluid sampling device that is used for vacuum pipe.
Background technology
In Chemical Manufacture, under the normal condition flowing liquid in the airtight vacuum pipeline is not needed to sample usually, therefore when the design of vacuum pipe, generally do not consider to be provided with the sampler of liquid, but under special circumstances, when finding that especially liquid component is undesired, need carry out sample analysis to it, just need this moment to consider to finish liquid sampling easily, can not influence the vacuum tightness of pipeline again.In present prior art, do not look into the correlation technique of in vacuum pipe, its working fluid being taken a sample as yet.
Summary of the invention
The utility model aims to provide a kind of device that working fluid in the vacuum pipe is taken a sample, and to realize finishing liquid sampling easily, can not influence the purpose of the vacuum tightness of pipeline again.
A kind of vacuum pipe fluid sampling device, mainly comprise vacuum pipe, valve 1, valve 2, valve 3, valve 4, it is characterized in that: valve 1 is installed in the vacuum pipe, valve 2 and valve 3 are installed on the vacuum tube at valve 1 two ends, the other end of valve 2 and valve 3 is connected by the U-shaped pipe, centre position at the U-shaped pipe connects valve 4, and the other end of valve 4 is the liquid sampling outlet.Under the normal condition, valve 1 is opened, and valve 2, valve 3 and valve 4 all keep closing, and liquid flows to the B end from the A end of vacuum pipe, during sampling, open valve 2 and valve 3, close valve 1, make the liquid certain hour that in the U-shaped pipe, flows treat that liquid is full of shut-off valve 2 and valve 3 behind the U-shaped pipe, open valve 1, make liquid recover normal and flow, open valve 4 at last, the liquid-like of staying in the U-shaped pipe is taken out.
Since when adopting the utility model to take a sample, can be by switching manipulation to valve, and vacuum pipe inner chamber and sampling outlet is isolated fully, so can the vacuum tightness of vacuum pipe not impacted, sampling operation is very simple and convenient simultaneously.
Description of drawings
Figure is the annexation synoptic diagram of this sampler.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Vacuum pipe fluid sampling device as shown in the figure mainly comprises vacuum pipe 6, valve 1, valve 2, valve 3, valve 4.Valve 1 is installed in the vacuum pipe, valve 2 and valve 3 are installed on the vacuum tube at valve 1 two ends, the other end of valve 2 and valve 3 is connected by U-shaped pipe 5, connects valve 4 in the centre position of U-shaped pipe 5, and the other end of valve 4 is the liquid sampling outlet.Under the normal condition, valve 1 is opened, and valve 2, valve 3 and valve 4 all keep closing, and liquid flows to the B end from the A end of vacuum pipe 6, during sampling, open valve 2 and valve 3, close valve 1, make liquid mobile certain hour in U-shaped pipe 5 treat that liquid is full of U-shaped pipe 5 back shut-off valve 2 and valves 3, open valve 1, make liquid recover normal and flow, open valve 4 at last, the liquid-like taking-up of staying in the U-shaped pipe 5 is got final product.
Claims (1)
