Description

Technical Field

[0001] This utility model relates to the technical field of oil samplers, specifically an oil sampler with a quantitative structure. Background Technology

[0002] Oil products refer to crude oil, petroleum products, stabilized light hydrocarbons, and stabilized condensate. my country's rapid economic development has driven a large demand for oil products. However, before these oil products are used, a series of tests are required on various substances to ensure their performance stability. Routine oil product testing items include: kinematic viscosity, water content, flash point, pour point and freeze point, sulfur content, density, distillation range, acid value, base value, color, carbon residue, ash content, calorific value, total precipitate, mechanical impurities, insoluble matter, water separability, etc., as well as the testing of the oil product's intrinsic quality. Before oil product testing, it is necessary to take samples. This is where a multi-point oil sampler with patent number "202223019436.4" comes in.

[0003] A multi-point oil sampler, currently patented under number "202223019436.4", includes a sampling head, a main structure, a connecting hose, and a sample storage bottle. The main structure is cylindrical and primarily used to generate negative pressure. A connecting hose is connected to the top of the main structure, and the sampling head is connected to the end of the connecting hose. A sample storage bottle is movably mounted on the side of the main structure. The main structure has a built-in piston chamber containing a piston, with a piston rod fixedly connected to the bottom of the piston. This invention is compact and easy to operate. It uses the piston to generate negative pressure to attract oil from the tank. The connecting hose is also marked with... The multi-point oil sampler with patent number "202223019436.4" has some defects. The sampler includes a connecting hose that can partially replace the dipstick and a detachable sampling bottle for repeated sampling. However, the sampling head still has flaws. Because it requires a slot to hold the sampling bottle for sampling, when dealing with different sized bottles (e.g., smaller bottles), the distance between the drain pipe and the bottle opening is too far, causing oil to splash and contaminate the equipment. Furthermore, the oil is easily affected by external environmental pollution, impacting the sampling results. Additionally, the hose's scale for quantitative oil sampling makes accurate quantitative sampling difficult, requiring re-quantification during subsequent testing, thus affecting testing efficiency. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide an oil sampler with a quantitative structure to solve the technical problems of oil splashing, susceptibility to external environmental contamination, difficulty in accurately completing quantitative sampling with the hose scale, and impact on detection efficiency caused by the excessive distance between the oil drain pipe and the sampling bottle opening when facing sampling bottles of different sizes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an oil sampler with a quantitative structure, comprising a main body, a snap-fit ​​mechanism, and a quantitative mechanism. The snap-fit ​​mechanism includes a first fixing plate, the outer surface of which has an installation groove, and a limit plate is provided inside the installation groove. A screw hole is provided at the bottom of the first fixing plate, and a screw rod is threadedly connected to the screw hole. A knob is provided at one end of the screw rod, and a snap-fit ​​plate is provided at the other end of the screw rod. A first snap-fit ​​groove is provided on the outer surface of the snap-fit ​​plate. A second fixing plate is provided above the first fixing plate, and a second snap-fit ​​groove is provided on the outer surface of the second fixing plate. The quantitative mechanism includes a first magnetic ring, which is magnetically connected to a second magnetic ring. A quantitative mark is provided on the outer surface of the main body.

[0006] By adopting the above technical solution, the screw hole and the screw rod are connected by threads, realizing the rotation and mobility of the screw rod, which facilitates the adjustment of the position of the snap-fit ​​plate.

[0007] Furthermore, a sampling tube is provided on the top of the main body, and a second one-way valve is provided on the sampling tube.

[0008] By adopting the above technical solution, during the sampling process, the second one-way valve allows the oil to flow into the sampling tube in one direction, but prevents the oil from flowing back.

[0009] Furthermore, a sampling head is provided at one end of the sampling tube, and an oil sampling hole is opened on the outer surface of the sampling head.

[0010] By adopting the above technical solution, and by setting up a sampling head and opening an oil sampling hole on its outer surface, the sampler can collect oil more efficiently.

[0011] Furthermore, a first fixing ring is provided above the second fixing plate, and an oil drain pipe is provided on one side of the first fixing ring, with a first one-way valve provided on the oil drain pipe.

[0012] By adopting the above technical solution and by setting the first fixing ring and the oil drain pipe, the sampler can orderly discharge oil from the piston chamber.

[0013] Furthermore, the main body has a piston chamber inside, and a piston is provided at the bottom of the piston chamber.

[0014] By adopting the above technical solution, the piston chamber, as a key component for oil sampling, can form a good seal between the piston inside and the chamber wall, effectively preventing oil leakage during the sampling process.

[0015] Furthermore, a push rod is provided at the bottom of the piston, and a push plate is provided at one end of the push rod.

[0016] By adopting the above technical solution and setting push rods and push plates, users can more conveniently push the piston to perform sampling operations.

[0017] In summary, the present invention has the following main advantages:

[0018] 1. This utility model achieves flexible adaptation to sampling bottles of different sizes by setting a snap-fit ​​mechanism. The first and second fixing plates in the snap-fit ​​mechanism can clamp sampling bottles of different sizes by adjusting the screw, ensuring that the sampling bottles are stably fixed during the sampling process, avoiding oil splashing and contamination problems caused by mismatched sampling bottle sizes. This not only improves the accuracy of sampling, but also enhances the versatility and practicality of the equipment.

[0019] 2. This utility model achieves precise quantitative sampling of oil by setting up a quantitative mechanism. The first and second magnetic rings in the quantitative mechanism, together with the quantitative mark on the main body, can accurately control the movement distance of the piston, thereby accurately controlling the amount of oil sampled. This quantitative method is simple, intuitive and easy to operate, improving the accuracy of sampling and detection efficiency. At the same time, the magnetic connection method also ensures the stability and durability of the quantitative mechanism. Attached Figure Description

[0028] The embodiments of this utility model will be described below based on its overall structure.

[0029] Oil samplers with quantitative structures, such as Figures 1-4 As shown, it includes a main body 1, a snap-fit ​​mechanism 5, and a metering mechanism 6. The snap-fit ​​mechanism 5 includes a first fixing plate 501, an installation groove 502 on the outer surface of the first fixing plate 501, a limit plate 503 inside the installation groove 502, a screw hole 504 at the bottom of the first fixing plate 501, a screw rod 505 connected to the screw hole 504 by threads, a knob 506 at one end of the screw rod 505, and a snap-fit ​​plate 507 at the other end of the screw rod 505. The outer surface of the snap-fit ​​plate 507 has a first snap-fit ​​groove 508. The upper part of the first fixing plate 501... The main body 1 is provided with a second fixing plate 509, and a second snap-fit ​​groove 510 is opened on the outer surface of the second fixing plate 509. The metering mechanism 6 includes a first magnetic ring 601, and the first magnetic ring 601 is magnetically connected to a second magnetic ring 602. A metering mark 603 is provided on the outer surface of the main body 1. The screw hole 504 is threadedly connected to the screw 505, realizing the rotation and mobility of the screw 505, which facilitates the adjustment of the position of the snap-fit ​​plate 507. The knob 506 provides a convenient operation method, allowing the user to easily rotate the screw 505 to adjust the snap-fit ​​plate 507.

[0030] See Figure 1 The top of the main body 1 is equipped with a sampling tube 2, and a second one-way valve 13 is installed on the sampling tube 2. During the sampling process, the second one-way valve 13 allows the oil to flow into the sampling tube 2 in one direction, but prevents the oil from flowing back. The sampling tube 2 extends into the oil to be sampled, and the oil extraction is easily completed, improving the sampling efficiency.

[0031] See Figure 1 , Figure 3 A sampling head 3 is provided at one end of the sampling tube 2. An oil collection hole 4 is provided on the outer surface of the sampling head 3. By setting the sampling head 3 and opening the oil collection hole 4 on its outer surface, the sampler can collect oil more efficiently. The sampling head 3 and the oil collection hole 4 make the sampling operation simpler.

[0032] See Figure 2 A first fixing ring 7 is provided above the second fixing plate 509, and an oil drain pipe 8 is provided on one side of the first fixing ring 7. A first one-way valve 9 is provided on the oil drain pipe 8. By setting the first fixing ring 7 and the oil drain pipe 8, the sampler can orderly discharge oil from the piston chamber 14. The first one-way valve 9 provided on the oil drain pipe 8 plays an important role in preventing backflow.

[0033] See Figure 4 The main body 1 has a piston chamber 14 inside, and a piston 12 is installed at the bottom of the piston chamber 14. As a key component for oil sampling, the piston chamber 14 has a good seal between the piston 12 inside and the chamber wall, which effectively prevents oil leakage during the sampling process. By moving the piston 12 up and down in the piston chamber 14, the amount of oil entering the sampler can be precisely controlled.

[0034] See Figure 4 A push rod 10 is provided at the bottom of the piston 12, and a push plate 11 is provided at one end of the push rod 10. By setting the push rod 10 and the push plate 11, the user can push the piston 12 more conveniently to perform sampling operations. The connection between the push rod 10 and the piston 12 ensures the direct transmission of pushing force and reduces the loss and instability in the process of force transmission.

[0035] The implementation principle of this utility model is as follows: First, the piston 12 is reset and the first magnetic ring 601 is pushed so that the second magnetic ring 602 is attached to the bottom of the piston 12. Then, the sampling bottle is placed in the first locking groove 508. Then, the knob 506 is turned so that the screw 505 drives the locking plate 507 to rise, so that the sampling bottle is in a suitable position. Then, the push plate 11 is pulled so that the push rod 10 drives the piston 12 to move, so that the oil enters the oil collection hole 4 and enters the piston chamber 14 through the sampling tube 2 and the second one-way valve 13. When the first magnetic ring 601 slides to the predetermined quantitative mark 603 position, the push plate 11 is pushed so that the push rod 10 drives the piston 12 to move, so that the oil enters the oil discharge pipe 8 through the first one-way valve 9 and is injected into the sampling bottle to complete the sampling.
