Description
Technical field
The utility model relates to samplers in a kind of lpg spherical tank tank, belong to detection field.
Background technique
Liquefied petroleum gas refers to that based on propane, butane, density is about 1.5~2.0 times of atmospheric density of liquefaction hydro carbons
Mixture, Pressure of Ambient Temperature storage are the storing modes that liquefied petroleum gas generallys use, and main storage facilities is Pressure of Ambient Temperature ball
Tank.The parameters such as pressure, temperature and page height in spherical tank have great significance for the safe storage of liquefied petroleum gas.Though
There is the Uniting standard of spherical tank in right country, but during long-time service, to the sample detecting of liquefied petroleum gas in spherical tank
It is also essential.
Liquefied petroleum gas sampling in spherical tank at present is generally from the inlet and outlet general pipeline that lpg spherical tank bottom picks out
It draws sampling pipeline and carries out enclosed sampling (sampling process is as shown in Figure 1), the sample of acquisition is Spherical Tank sample, spherical tank 100
Bottom is equipped with oil gas general pipeline 1, drainpipe 2, sampling pipe 3 and closed sampler 4, oil gas general pipeline 1, drainpipe 2 and sampling pipe 3
It is opened on the bottom of spherical tank 100, therefore picking out for sampled point is a little imported and exported on general pipeline in liquefied petroleum gas.But due to liquefied gas
In contain moisture, and relative density of the liquefied petroleum gas under room temperature, 0.9MPa state is 0.55, therefore after running a period of time
Tank bottom bottom has the water layer of certain liquid level, and water layer top is liquefied petroleum gas, therefore when routine sampling, sampling pipe 3 is collected
Liquefied petroleum gas be possible to entrainment large quantity of moisture, and cannot really reflect liquefied petroleum gas quality in tank, this gives testing result
Accuracy bring very big puzzlement.
Utility model content
In view of the above problems existing in the prior art, the purpose of the utility model is to provide a kind of lpg spherical tank use
Sampler in tank.
To realize that above-mentioned purpose of utility model, the technical solution adopted in the utility model are as follows:
Sampler includes a sampling tubule and a fixed bracket in the lpg spherical tank tank, samples tubule one end
It is extended in lpg spherical tank in liquefied petroleum gas inner manifold, sampling tubule is set in spherical tank inner height more than ponding layer
Highly, the sampling tubule other end connects sampling pipe；Fixed branch is set up in liquefied petroleum gas general pipeline, clamping sampling tubule.Sampling

The liquefied petroleum gas collected enters closed sampler by sampling pipe and carries out concentration determination, and gas is gone by blow-down pipe after sampling
Torch general pipeline emptying.
Preferably, the sampling tubule is parallel to liquefied petroleum gas general pipeline.
Preferably, the sampling tubule is angle in spherical tank inner opening.
It is furthermore preferred that the angle and tubule wall angle are 20~80 °.The angle of preferred angle and tube wall is 60 °,
Tubule angle increases the forced area of tubule mouth, reduces pressure, so that the liquefied petroleum gas in 100 in spherical tank is easier to flow
Out, tubule mouth will not be caused to be closed since ball pressure inside the tank is excessive.
Preferably, the sampler further includes moisture content detection device.
It is furthermore preferred that the moisture content detection device is moisture detector in pipeline.
It is furthermore preferred that sampling pipe one end connection sampling tubule, one end connects closed sampler.
It is furthermore preferred that the moisture detector is set to sampling pipe close to the side of closed sampler.Moisture detector can be into
Whether the liquefied petroleum gas that one step confirmation sampling tubule is collected into is the gas without containing moisture, if detecting liquefied petroleum gas
Inside contain moisture, correcting action can be played for testing result, while liquid level meter being assisted to judge whether water layer height exceeds mark
Quasi- value, to carry out drainage works in time.
As a preferred embodiment, sampling tubule is drawn through sampling by the side liquefied petroleum gas general pipeline opening
Pipe is connected to closed sampler.
Compared with prior art, sampler provided by the utility model can enable assay personnel take liquefied petroleum
More representational liquefied petroleum gas in balloon tank collects the sample closer under time of day, is conducive to workshop
Control to liquefied petroleum gas quality reduces product disqualification rate, indirect saving production cost.
