Abstract
The utility model discloses an L. P. G. Ship's hold sampling device, comprising a chuck whose one side is provided with a liquid inlet valve. The liquid inlet valve is connected with a flow meter which is connected with a connecting rod; a joint for connecting a hold liquid level gauge rod is also provided. The front end of the connecting rod is connected with the back end of the joint; the other side of the chuck is provided with a liquid outlet valve, and is sheathed with a liquid containing tank. The utility model has advantages of convenient sampling, small size, convenient operation, high sampling speed, strong versatility, and good safe performance.
Description
The utility model relates to the test of measuring technique or the sampler in the analysis of material, is the sampler of a kind of liquid or fluid, specifically, is a kind of sampler of drawing sample at several surface levels that has.
The international trade of liquefied petroleum gas (LPG) is mainly by special-purpose ship transportation, to general international standard type LPG ship, all preset the sample that gauge orifice is used to extract hold cargo at each cabin.At present, international, domesticly all generally adopt gauge orifice sampling, its device is approved product, and its subject matter is: 1. for each cabin, no matter goods what, all can only extract the sample of a certain point of fixity in the cabin, can't change sample point; 2. for cabin internal fixation point, need extract a considerable amount of samples according to standard, operation inconvenience, and waste time and energy; 3. because liquefied petroleum gas (LPG) is made up of many components lighter hydrocarbons, and the physicochemical property of different aspects sample differs greatly in the cabin, only depend on some sampling in the cabin, no matter amount of sampling is much, all can not represent the character of whole hold cargo thing; 4. sampling is big with disposable consumable material consumption, sampling cost height, because the point of fixity amount of sampling is big, every cabin need consume two of 15kg steel cylinders (being roughly equal to 300 yuan of Renminbi) at least, two in 220ml special pressure jar (being roughly equal to 20 yuan of Renminbi), and package unit heaviness, volume are big, easily leak, sample size is difficult to control, brings many-sided danger to sampling on the ship.
The purpose of this utility model provides the liquefied petroleum gas (LPG) cabin sampler of a kind of sampling operation convenience, versatility and high safety.
Technical solution of the present utility model is; A kind of liquefied petroleum gas (LPG) cabin sampler, adopted to be different from the prior art constructions design: a dop is arranged, and dop one side is equipped with the feed liquor valve, and the feed liquor valve links to each other with a flowmeter, and flowmeter is connected to connecting link; Other has one to be used for the joint that joins with the Marine Tank Level bar, and aforementioned connecting link front end is connected with the joint rear end; The dop opposite side is equipped with the feed liquor valve, and is set with the appearance flow container.
Feed liquor valve described in the utility model adopts spring valve.Certainly, also can adopt the valve of other suitable construction.
A cleaning cross-over valve that is used for the liquid valve changing-over is arranged in the utility model in addition.Certainly, also can adopt other suitable construction forms.
Connecting link front end described in the utility model is equipped with and is used for the connecting link joint that links to each other with aforementioned joint.Certainly, also can adopt other suitable versions.
The utility model has the advantages that: 1. sampling is convenient, can extract the sample of any liquid level layer in the cabin easily; 2. volume is little, in light weight, only is about 1/20th of existing apparatus; 3. easy to operate, use flexibly, running cost is low, whenever gets a sample and only need consume one in 220ml special pressure jar, saves about 150 yuans than the every sample of existing apparatus; 4. operating speed is fast, whenever gets the same institute time-consuming and only is about 1/20th of existing apparatus; 5. highly versatile to general international standard type liquefied gas carrier, is no matter when and where made, and can both be suitable for; 6. security performance is strong, and the package unit good airproof performance do not have to leak, and is easy to carry, saves time, laborsaving.
The utility model is described in further detail below in conjunction with drawings and Examples:
Accompanying drawing is the structural representation of a kind of liquefied petroleum gas (LPG) cabin sampler of the present utility model.
Accompanying drawing has been described an embodiment of the present utility model.In this example based on a dop 6, a spring valve 5 is equipped with as the feed liquor valve in dop 6 front sides, spring valve 5 is connected with a flowmeter 4 (commercially available prod), flowmeter 4 is connected with a connecting link 3, connecting link 3 front ends are equipped with connecting link connector 2, and other has a joint 1 to be used for being connected with existing Marine Tank Level bar.Dop 6 rear sides are equipped with a spring valve 7 as the feed liquor valve.Also be set with special pressure jar 8 (adopting existing 220ml special pressure jar) on the dop 6.Other has a cleaning cross-over valve accessory.
During use: 1. first regulator solution gasification cabin sounding rod is to required sampling liquid level, because the cabin internal pressure is generally 0.8-1.2MPa, so can satisfy sampling requirement by liquid in the cabin fully from pressing.
2. drain the interior liquid level of cabin to the gas of measuring the sample fluid hole, to there being liquid to discharge valve-off.
3. joint 1 is received the sounding rod fluid hole, again connecting link etc. is connected with joint 1.
4. spring valve 7 is unloaded, will clean cross-over valve and be loaded on dop 6 relevant positions, open sounding rod valve etc., adjusting flow velocity to flowmeter 4 tabular values is 3-6l/min; About 1 minute of emptying will be cleaned cross-over valve again and be changed, and load onto spring valve 7 and special pressure jar 8, and topping up 10-20 second, back valve-off unloads special pressure jar 8 (sampling jar), promptly finish once sampling.Dop and spring valve, cleaning cross-over valve are by the interconnection of cassette jointing, and all joints adopt teflon seals.Joint, valve, sample pot, connecting link etc. are good to adopt stainless steel products all.
