Description

Technical Field

[0001] The invention discloses a gas-liquid split-flow multifunctional liquid sampler and a use method thereof, which relates to a device for liquid sampling and a use method of using the device for sampling. Background Art

[0002] In many occasions, liquid sampling is required, especially in places where oil and liquid chemicals are stored. The representativeness of oil sampling can directly affect the representativeness of oil quality inspection results. The existing samplers have different diameters and injection speeds, but the injection and exhaust are the same during sampling. For example, when sampling in a gasoline tank, the plug of an empty sampler is opened, and the gasoline sample enters the sampler from the sampler port, and the gas in the sampler is blown out from the sampler port. The one-liter gasoline sample entering the one-liter sampler must be subjected to the impact, blowing, and volatilization of one liter of gas. Experiments have found that when gasoline samples are sampled through this type of sampler, their density will increase by one to three thousandths, and the vapor pressure of gasoline will be low. The problem is that this type of sampler is still used to sample and measure the density of gasoline. First, sampling, second, pouring into an oil sample bottle, and third, pouring from the oil sample bottle into a measuring cylinder to measure the density. The gasoline sample has volatilization losses of light components in these three links, and the flash point of jet fuel and diesel will also be higher. The judgment of oil quality is often not accurate enough, so it is necessary to provide a new sampler to meet the sampling needs. Summary of the invention

[0014] The bottle body is a cylindrical bottle body.

[0015] Furthermore, the bottle body is formed by sealingly connecting a cylindrical bottle body and a liquid inlet mechanism at the bottom of the bottle; preferably, the connection is spiral.

When the bottle body and the bottle bottom liquid inlet mechanism are connected in a spiral seal, the bottle bottom liquid inlet mechanism can be disassembled or installed on the bottle body by twisting the torsion bar by hand.

[0022] Furthermore, an annular step is provided on the lower surface of the base, and a groove corresponding to the torsion bar is provided on the step. The torsion bar can be placed in the groove, and rotating the torsion bar can rotate the base, thereby opening or closing the base, and saving space at the bottom tail.

[0023] A dimension gauge can be sprayed on the bottle, or a pressure strip can be fixedly installed on the outer wall of the bottle, and a dimension gauge is installed or engraved on the pressure strip. The dimension gauge can measure the height of the sample liquid stored in the bottle.

[0024] The gas-liquid split-flow multifunctional liquid sampler of the present invention can be used to sample, check the quality of sample liquid, store sample liquid and measure the defoaming time of sample liquid.

[0025] The bottle body is made of a transparent material, preferably glass, and more preferably tempered glass, which can effectively prevent external impact and withstand the extrusion of the sample liquid on the bottle body to prevent deformation.

[0026] A gas-liquid split-flow multifunctional liquid sampler can take spot samples at a certain point in a container, take bottom samples and take full-layer samples when sampling.

[0027] A method for sampling a gas-liquid split-flow multifunctional liquid sampler is as follows:

[0028] The sampling cover with the rope control device fixedly installed is sealed and connected to the bottle body;

[0029] According to the liquid inlet speed requirement, rotate the adjustment slot on the liquid inlet adjustment plate to the predetermined position;

[0030] The rope hook is inserted into the K-shaped top rod, and the rope hook and the K-shaped top rod are in a locked state;

[0031] The sampling rope is extracted by hand, and the gas-liquid split-flow multifunctional liquid sampler of the present invention is smoothly placed into the container to be sampled;

[0032] After the sampler is lowered to the predetermined depth, the sampling rope is quickly lifted up for a distance and lowered to the original position. The spring in the spring sleeve is used to push the K-shaped push rod downward to pop out the rope hook and unlock it.

[0033] The through-hole shaft moves downward under the action of gravity, and the liquid inlet control valve plate moves downward, opening the liquid inlet channel 1 and the exhaust chamber, and the sample liquid enters the bottle body through the liquid inlet channel 1 on the cover body, and the sample liquid flows smoothly along the drainage plate, and then flows slowly along the bottle wall of the bottle body through the liquid inlet groove or the liquid inlet hole on the drainage plate, thereby reducing the impact force when flowing in;

[0034] The gas to be discharged in the bottle body is discharged through the upper exhaust channel and the lower exhaust channel on the through-hole shaft into the exhaust chamber, and the gas is further discharged upward through the gap in the spring sleeve;

[0035] After the gas is completely discharged and the bottle is filled with sample liquid, pick up the sampling rope and take out the sampling container.

[0036] A method for taking a bottom sample with a gas-liquid split-flow multifunctional liquid sampler is as follows:

[0037] The sampling cover with the rope control device fixedly installed is sealed and connected to the bottle body;

[0038] Rotate the adjustment slot on the liquid inlet adjustment plate to a predetermined position;

[0039] The rope hook is inserted into the K-shaped top rod, and the lock tube is rotated upward to block the hook groove. The rope hook and the K-shaped top rod are always in a locked state;

[0040] Take out the sampling rope by hand, and steadily put the gas-liquid split-flow multifunctional liquid sampler of the present invention into the bottom of the container to be sampled, and put the sampling rope in a relaxed state;

[0041] When the sampling rope is in a relaxed state, the push rod pushes the liquid inlet control valve to move upward along the second liquid inlet channel, and the second liquid inlet channel and the liquid inlet hole are converted from a closed state to a connected state. The sample liquid at the bottom smoothly enters along the bottom of the bottle body through the second liquid inlet channel, and the liquid is also introduced into the first liquid inlet channel on the sampling cover at the same time. At the same time, the gas in the bottle body is discharged upward through the exhaust chamber on the sampling cover;

[0042] After the gas to be discharged in the bottle body is completely discharged through the upper exhaust passage and the lower exhaust passage of the through-hole shaft into the exhaust chamber, and the sample liquid in the bottle body and the sample liquid layer at the bottom of the container achieve pressure balance, and the sample liquid in the bottle body and the actual liquid layer distribution of the liquid in the container are consistent, the gas-liquid diversion type multifunctional liquid sampler of the present invention is lifted upwards using a sampling rope, and the bottom sampling is completed by lifting out the container to be sampled.

[0043] A method for taking a full-layer sample using a gas-liquid split-flow multifunctional liquid sampler is as follows:

[0044] The sampling cover with the rope control device fixedly installed is sealed and connected to the bottle body;

[0045] According to the liquid inlet speed requirement, rotate the adjustment slot on the liquid inlet adjustment plate to the predetermined position;

[0046] The rope hook is inserted into the K-shaped top rod, the rope hook and the K-shaped top rod are in a locked state, and the lock tube is adjusted downward to keep the hook slot open;

[0047] The sampling rope is extracted by hand, and the gas-liquid split-flow multifunctional liquid sampler of the present invention is smoothly placed into the container to be sampled;

[0048] After the sampler is lowered to a depth close to the bottom of the container, the sampling rope is quickly lifted up for a distance and lowered to the original position. The spring in the spring sleeve is used to push the K-shaped push rod downward to pop out the rope hook and unlock it.

[0049] The through-hole shaft moves downward under the action of gravity, and the liquid inlet control valve plate moves downward, opening the liquid inlet channel 1 and the exhaust chamber, and the sample liquid enters through the liquid inlet channel 1 on the cover body, flows smoothly along the drainage plate, and then flows slowly along the bottle wall of the bottle body through the liquid inlet groove or the liquid inlet hole on the drainage plate, thereby reducing the impact force when flowing in;

[0050] The gas to be discharged in the bottle body is discharged through the upper exhaust channel and the lower exhaust channel of the through-hole shaft into the exhaust chamber, and the gas is further discharged upward through the gap in the spring sleeve;

[0051] While the bottle is being filled with liquid and exhausted, lift the sampling rope upwards at a uniform speed until the container to be sampled is completely lifted out. When the container is completely taken out, the sample liquid injected into the bottle cannot fill the bottle (if it is completely full, the full-layer sampling fails and resampling is required until it is not full).

[0052] The method for judging the appearance of a sample liquid using a gas-liquid split-flow multifunctional liquid sampler is as follows:

[0053] The height-adjusting ring is used to lift the step three, thereby causing the through-hole axis to move upward, and the liquid inlet control valve plate closes the liquid inlet channel one and the channel of the exhaust chamber;

[0054] Twist the torsion bar to unscrew the bottom liquid inlet mechanism from the bottle body, turn the bottle body 180°, inject the sample liquid to be tested into the bottle body from the original bottom of the bottle, and visually observe the appearance quality of the sample liquid.

[0055] The method for measuring the defoaming time of a sample liquid using a gas-liquid split-flow multifunctional liquid sampler is as follows:

[0056] The height-adjusting ring is used to lift the step three, thereby making the through-hole axis move upward, and the liquid inlet control valve plate closes the liquid inlet channel one and the channel of the exhaust chamber, so that the sample liquid in the bottle body cannot flow out from the sampling cover;

[0057] Twist the torsion bar to unscrew the bottom liquid inlet mechanism from the bottle body, turn the bottle body 180°, and inject the sample liquid to be tested into the bottle body from the original bottom of the bottle. The sample liquid does not need to fill the bottle body (the volume of the sample liquid is half of the bottle body volume), and tighten the bottom liquid inlet mechanism;

[0058] Shake the bottle and use a timer to measure the time it takes for the bubbles to disappear in the sample liquid to complete the measurement.

[0059] The invention discloses a gas-liquid split-flow multifunctional liquid sampler, which is ingenious in design, easy to use, has good use detection effect, has multiple uses through different state settings, and has good use flexibility and application promotion value.

[0107] After the gas to be discharged in the bottle body 1 is completely discharged through the upper exhaust channel 4-1-2 and the lower exhaust channel 4-1-3 of the through-hole shaft 4 and the exhaust chamber 4-4, and the sample liquid in the bottle body 1 and the sample liquid layer at the bottom of the container achieve pressure equilibrium, and the sample liquid in the bottle body 1 is consistent with the actual liquid layer distribution of the liquid in the container, the sampling rope 19 is used to lift up the gas-liquid diversion type multifunctional liquid sampler of the present invention, and the bottom sampling is completed by lifting out the container to be sampled.

[0108] A method for taking a full-layer sample using a gas-liquid split-flow multifunctional liquid sampler is as follows:

[0109] The sampling cover with the rope control device fixedly mounted thereon is sealedly connected to the bottle body 1;

[0110] According to the liquid inlet speed requirement, the adjusting slot 7-1 provided on the liquid inlet adjusting plate 7 is rotated to a predetermined position;

[0111] The rope hook 11 is inserted into the K-shaped top rod 18, the rope hook 11 and the K-shaped top rod 18 are in a locked state, and the lock tube 16 is adjusted downward to keep the hook slot 17 normally open;

[0112] Use your hands to extract the sampling rope 19, and steadily place the gas-liquid split-flow multifunctional liquid sampler of the present invention into the container to be sampled;

[0113] After the sampling rope 19 is lowered to a depth close to the bottom of the container, the sampling rope 19 is quickly lifted up for a distance and lowered to the original position, and the spring 13 in the spring sleeve 14 is used to push the K-shaped push rod 18 downward to pop out the rope hook 11 and unlock it;

[0114] The through-hole shaft 4 moves downward under the action of gravity, and the liquid inlet control valve plate 5 moves downward, opening the liquid inlet channel 4-1-1 and the exhaust chamber 4-4, and the sample liquid enters through the liquid inlet channel 4-1-1 on the cover body, flows smoothly along the drainage plate 5-2, and then flows slowly along the bottle wall of the bottle body 1 through the liquid inlet groove or the liquid inlet hole on the drainage plate 5-2, thereby reducing the impact force when flowing in;

[0115] The gas to be discharged in the bottle body 1 is discharged through the upper exhaust channel 4-1-2 and the lower exhaust channel 4-1-3 of the through-hole shaft 4 into the exhaust chamber 4-4, and the gas is further discharged upward through the gap in the spring sleeve 14;

[0116] While the bottle 1 is being filled with liquid and exhausted, the sampling rope 19 is lifted upward at a uniform speed until the container to be sampled is completely lifted out. When the container is completely taken out, the sample liquid injected into the bottle 1 cannot fill the bottle (if it is completely full, the full-layer sampling fails and resampling is required until it is not full).

[0117] The method for judging the appearance of a sample liquid using a gas-liquid split-flow multifunctional liquid sampler is as follows:

[0118] The step three 4-3 is lifted by the height adjustment ring 6, so that the through-hole shaft 4 moves upward, and the liquid inlet control valve plate 5 closes the liquid inlet channel 1 4-1-1 and the channel of the exhaust chamber 4-4;

[0119] Twist the torsion bar 10-3 to unscrew the bottom liquid inlet mechanism from the bottle body 1, turn the bottle body 180 degrees, inject the sample liquid to be tested into the bottle body 1 from the original bottle bottom, and visually observe the appearance quality of the sample liquid.

[0120] The method for measuring the defoaming time of a sample liquid using a gas-liquid split-flow multifunctional liquid sampler is as follows:

[0121] The height-adjusting ring 6 is used to lift the step three 4-3, thereby causing the through-hole shaft 4 to move upward, and the liquid inlet control valve plate 5 closes the liquid inlet channel one 4-1-1 and the channel of the exhaust chamber 4-4, so that the sample liquid in the bottle body 1 cannot flow out from the sampling cover;

[0122] Twist the torsion bar 10-3 to unscrew the bottom liquid inlet mechanism from the bottle body 1, turn the bottle body 1 180°, and inject the sample liquid to be tested into the bottle body 1 from the original bottom of the bottle. The sample liquid does not need to fill the bottle body 1 (the volume of the sample liquid is half of the volume of the bottle body 1), and tighten the bottom liquid inlet mechanism;

[0123] The bottle body 1 is shaken, and the disappearance time of the bubbles in the sample liquid is measured by a timer to complete the measurement.
