Description

Technical Field

[0001] The utility model relates to the technical field of sampling valves, in particular to a sampling device for lubricating oil processing. Background Art

[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the role of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering. During the production process of lubricating oil, it is necessary to sample and test the lubricating oil. In the existing technology, sampling is mostly carried out through pipeline sampling valves.

[0003] In the prior art, the flow rate of the pipeline sampling valve is inconvenient to control. When the pressure in the pipeline is too high, the valve opening is very small, and more lubricating oil will flow out, causing the lubricating oil to easily overflow from the sampling bottle during sampling. After the sampling is completed, a small amount of lubricating oil will remain in the sampling valve pipeline, causing the sampling valve to drip. The lubricating oil drips onto the ground and corrodes the floor. Therefore, a sampling device for lubricating oil processing is needed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] See also Figure 1-Figure 4 , a sampling device for lubricating oil processing, comprising a sampling valve 1, a sampling tube 120 is arranged on the sampling valve 1, a material receiving mechanism 2 is arranged on the sampling valve 1, and an emptying valve 3 is arranged on the sampling tube 120;

[0022] The material receiving mechanism 2 includes a collar 210, a connecting rod 220, a support plate 230 and a waste bucket 240. The collar 210 is sleeved on the sampling valve 1 and rotatably connected thereto. The top of the connecting rod 220 is fixedly connected to the bottom of the collar 210. The bottom of the connecting rod 220 is fixedly connected to the upper end surface of the support plate 230. The waste bucket 240 is detachably mounted on the lower end surface of the support plate 230.

[0023] When the device is in use, the sampling container is placed at the center of the support plate 230, and the sampling valve 1 is opened to allow the lubricating oil in the pipeline to flow into the sampling container from the sampling tube 120. When the sampling container is almost full, the sampling valve 1 is closed, and the valve cover 302 of the drain valve 3 is loosened to allow air to enter the sampling tube 120 from the drain valve 3, and the sampling tube 120 is emptied. The sampling container is filled to the standard scale, and the valve cover 302 of the drain valve 3 is tightened again. A small amount of lubricating oil in the sampling tube 120 drips into the waste barrel 240, and the waste barrel 240 is removed regularly for cleaning.

[0024] Furthermore, the top outer end surface of the waste barrel 240 is provided with an external thread, and the bottom inner end surface of the support plate 230 is provided with an internal thread, and the support plate 230 and the waste barrel 240 are threadedly connected through the matching internal and external threads.

[0025] The threaded connection structure makes it easy to remove the waste barrel 240 and clean the waste inside it, thereby improving the convenience of equipment cleaning.

[0026] Furthermore, the upper end surface of the support plate 230 is a hollow structure.

[0027] The support plate 230 can support the sampling bottle, and the leaked or overflowed lubricating oil can flow into the waste barrel 240.

[0028] Furthermore, the connecting rod 220 is composed of a sleeve 221 , a sliding rod 222 and a spring 223 . The spring 223 is sleeved on the outer end of the sliding rod 222 . The sliding rod 222 and the sleeve 221 are elastically connected via the spring 223 .

[0029] Through the cooperation of the sliding rod 222, the sleeve 221 and the spring 223, the connecting rod 220 can be elastically extended and retracted, so that the support plate 230 can use sampling bottles of different heights. When sampling for the first time, the sampling bottle can be placed on the required tube to prevent material splashing. As the material increases, the sampling bottle gradually descends, which is convenient for the final adjustment of the sampling volume.

[0030] Furthermore, the collar 210 is sleeved on the sampling valve 1 and is rotatably connected thereto via a damping bearing.

[0031] The collar 210 can rotate along the sampling valve 1. When the sampling bottle is too long to be placed on the support plate 230, the support plate 230 can be pushed sideways, so that the sampling bottle can be conveniently placed on the sampling tube 120 for sampling.

[0032] Furthermore, the sampling tube 120 is an “L”-shaped structure, and the drain valve 3 is installed on the top of the sampling tube 120 . The drain valve 3 is composed of a valve body 301 and a valve cover 302 , and the valve cover 302 is threadedly connected to the valve body 301 .

[0033] When the sampling bottle is almost full, the drain valve 3 is opened to allow external air to enter the sampling tube 120, thereby discharging the residual lubricating oil in the sampling tube 120 and filling the sampling bottle. On the one hand, the sampling accuracy is improved, and on the other hand, the waste of raw materials in the sampling tube 120 is reduced.

[0034] Furthermore, a sampling tube 110 is disposed at the front end of the sampling valve 1 , and a plurality of sampling holes 101 are disposed on the side of the sampling tube 110 .

[0035] The sampling depth is increased by the sampling tube 110, thereby improving the detection accuracy.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
