Description
Technical field
The utility model relates to a kind of liquid petroleum sampler, and more particularly, it relates to the good manual machinery switching regulator liquid petroleum grab sampling device of a kind of sample representation.
Background technology
The sampling method of liquid petroleum has the branch of automatic sampling method and manual sampling method, at present in the world to the sampling of static liquid oil still based on manual sampling method, especially in all kinds of storage tank to the sampling of static liquid oil.The purpose of sampling is that in accordance with regulations method obtains representative sample, is used for the physico-chemical analysis to the every index of grade of oil.In the oil work for inspection, sampling is an indispensable important step in the work for inspection, is to guarantee accurate, the reliable precondition of analytical test result.If the sample of getting does not have representativeness, the data that lab investigation are analyzed just lose meaning, even can cause the mistake in the quality judgement, bring unnecessary influence and loss for industrial and agricultural production and use.It is a vital job that therefore correct sampling obtains representative sample.
CNPC's consumption was near 500,000,000 tons in 2012, surpass 56% crude oil dependence on import, raising along with the external degree of dependence on inport of CNPC, the also diversification of Imported oil kind, be example with the port, Zhoushan, surpassed 2,500 ten thousand tons from port, Zhoushan Imported oil in 2012, the Imported oil place of production has from a countries and regions surplus Saudi Arabia, the Sudan, Oman, Venezuela, Iran, Brazil, the Indonesia etc. ten.The particularly increase of high viscosity, high pour point, highdensity heavy crude and fuel oil in recent years, make oil arrive oil complex distribution behind the bank jar, lamination is serious, especially some are in harmonious proportion fuel oil, the oil quality of its mediation is different, in the bank jar, cause layering easily, may deposit heavier oil product in the bottom, and it is lighter relatively at the oil density on upper strata, and the relation of the distribution of this weight oil product and liquid level does not have fixing regularity, therefore adopt 3 samplings in upper, middle and lower with the routine sampling device, the sample representativeness of obtaining is often not enough.Should strengthen sampling spot in this case and obtain representative sample with assurance, but the routine sampling device is difficult to accurately hold the position of sampling spot, in the process that sample bucket promotes, a part of oil product in the bucket will exchange outward with bucket inevitably, and sampling accuracy, representativeness are had a greatly reduced quality.Therefore it is very important to develop a kind of sampling instrument simple, safe, easy to operate, that can be sampled to representative oil sample.Manual oil sampler at present both at home and abroad commonly used has: sampling cage sampler, interface sampler, and customary sampler etc., but the oil sample that the sampling of the sampler of these types obtains is representative relatively poor, can not accurately embody the quality of oil.
Chinese patent notification number CN202453217U discloses a kind of oil tank sampler, ullage rule, comprises sampling jar, the oral area of sampling jar arranges bottle stopper, one end of ullage rule connects inner core, and the lower end of inner core is connected with bottle stopper by connection cord, and pin shaft hole radially is set on the inner core, inner core is nested with a urceolus outward, the bearing pin that cooperates with pin shaft hole is set on the urceolus, connects stage clip on the urceolus, stage clip is arranged on the outer end of bearing pin, the lower end of urceolus connects folder bottle pawl by wire rope, and folder bottle pawl is connected with sampling jar.This sampling jar is simple in structure, and the sample position is accurate, but the degree of depth that sampling jar is placed is more dark, and the pressure of the liquid that bottle stopper is subjected to is more big, and often can't open bottle stopper by the moment pulling force of connection cord this moment.If the bottle stopper plug is too loose before sampling jar is transferred, cause liquid before not arriving assigned address, just to fill in the sample bucket easily, greatly reduce the representativeness that obtains oil sample.
The utility model content
The utility model has overcome the representative relatively poor of oil sample that the sampling of existing oil sampler obtains, can not accurately embody the deficiency of grade of oil, a kind of manual machinery switching regulator liquid petroleum fixed point sampler is provided, its oil sample of obtaining of sampling representative good, can accurately embody the quality of oil, and the position that sample bucket is transferred is accurate, the quality of the oil product that obtains each position of more accurately taking a sample.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: a kind of manual machinery switching regulator liquid petroleum fixed point sampler, comprise base, be placed in the sample bucket on the base, fixedly connected support on the base, reel has been rotatably connected on the support, be wound with the brake spool on the reel, be provided with brake cable in the brake spool; Be provided with sampling cavity in the sample bucket, the sampling cavity upper end position is provided with piston in the sample bucket, and the outer wall that sample bucket arranges piston position is provided with sampling window, the truncated cone-shaped that piston is big up and small down, and the piston upper end is connected with retracing spring; The two ends of brake spool are connected to respectively on sample bucket and the support, and an end of brake cable is connected on the piston and can upwards spurs piston, and the other end of brake cable connects the piston pull unit.
