Description

Technical Field

[0001] The utility model relates to the technical field of oil samplers, in particular to a closed oil tank truck oil full-course sampler. Background Art

[0002] An oil sampler is a tool for oil testing. When it is working, one end is connected to the oil outlet of the oil tank, and the other end is connected to the oil storage tank at a gas station or other place through a pipeline. By opening the control valve on the sampler, the gasoline and diesel in the oil tank can flow into the oil storage tank. During the oil unloading process, the staff can open the sampling valve on the sampler to sample and test the gasoline and diesel in the oil tank. Existing samplers generally adopt the principle of random sampling, that is, during the oil unloading process, oil samples are randomly discharged for testing. During the entire oil unloading process, the staff cannot visually observe the state of the oil with the naked eye, so it is easy to miss the inspection when sampling, which makes it impossible to fully guarantee the quality of gasoline and diesel, thereby unable to ensure the quality and safety of oil products, which brings great inconvenience to the oil testing work. Utility Model Content

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a closed oil tank truck oil product full-process sampler, including a metering cabin, a male end of an oil drain joint is arranged at the left end of the metering cabin, a quick joint is arranged at the right end of the metering cabin, a control valve is also arranged on the side of the metering cabin close to the male end of the oil drain joint, an oil sighting tank for observing the oil sample inside the metering cabin is also arranged in the middle of the metering cabin, a sampling joint is arranged at the lower end of the metering cabin, a detection port is also arranged at the top of the oil sighting tank, and a sealing head is arranged at the detection port.

[0005] Furthermore, the oil sight tank is horizontally placed in the middle of the metering tank, the oil sight tank and the metering tank are arranged in a cross shape, and the oil sight tank is provided with oil sight windows at both ends thereof.

[0006] Furthermore, a plurality of sealing grooves are arranged on the sealing head in the vertical direction, and sealing rings are sleeved on the sealing grooves, and the sealing rings are tightly fitted on the inner wall of the detection port.

[0007] Furthermore, a detection ruler extending into the sight oil tank is provided at the lower end of the sealing head.

[0008] Furthermore, an operating ring is provided on the top of the sealing head.

[0009] Furthermore, an anti-overflow exhaust valve is also provided on the top of the metering cabin.

[0010] Furthermore, the control valve is a butterfly valve, and the control valve controls the valve plate to rotate in the metering cabin through a rocker.

[0011] Furthermore, a sampling valve is provided on the sampling joint.

[0012] Furthermore, a lifting handle is provided on the top of the metering cabin.

[0013] The above technical scheme of the utility model has the following beneficial effects: the utility model arranges an oil sight tank on the metering tank and arranges a detection port at the oil sight tank, so that the staff can observe the appearance, color and water impurities of the oil with the naked eye during the oil unloading process. If the oil is abnormal, the staff can conduct a rapid detection through the detection port, so as to sample the abnormal oil in real time to facilitate subsequent detection, so as to better control the quality of the oil, thereby ensuring the quality and safety of the oil.

[0018] In order to more clearly understand the above-mentioned purposes, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0020] like Figure 1-4As shown, the closed tank truck oil full-course sampler described in this embodiment includes a metering cabin 1, a male end 2 of an oil drain joint is provided at the left end of the metering cabin 1, a quick connector 3 is provided at the right end of the metering cabin 1, a control valve 4 is also provided on the side of the metering cabin 1 close to the male end 2 of the oil drain joint, an oil sighting tank 5 for observing the oil sample inside the metering cabin 1 is also provided in the middle of the metering cabin 1, a sampling joint 6 is provided at the lower end of the metering cabin 1, a detection port 7 is also provided on the top of the sighting tank 5, and a sealing head 8 is provided at the detection port 7.

[0021] The oil sight tank 5 is horizontally placed in the middle of the metering tank 1, and the oil sight tank 5 and the metering tank 1 are arranged in a cross shape. The oil sight tank 5 is provided with oil sight windows 9 at its two ends. The oil sight windows 9 are large glass windows. When unloading oil, the staff can observe the oil inside the sampler through the oil sight windows 9.

[0022] A plurality of sealing grooves are arranged on the sealing head 8 along the vertical direction, and sealing rings 10 are sleeved on the sealing grooves. The sealing rings 10 are tightly fitted on the inner wall of the detection port 7 .
