Description

Technical Field

[0001] The utility model relates to the technical field of sampling equipment, in particular to a simple hydraulic oil sampling anti-pollution device. Background Art

[0002] With the development of the steel industry, hydraulic systems are increasingly being used in mechanical equipment. For the hydraulic system to operate safely and reliably, its oil must ensure qualified cleanliness. Oil contamination can cause failure of hydraulic system control components and wear of actuators. In order to understand the operating status of the oil, it is necessary to regularly sample and test the oil in the hydraulic system. However, in the oil sampling process, due to the presence of many pollutants in the on-site environment and the unsealed sampling bottles used, it is easy to mix pollutants in the on-site environment into the oil sample bottle, resulting in unqualified oil sample test results. Therefore, it is necessary to design a simple hydraulic oil sampling anti-pollution device to ensure the authenticity and reliability of the oil sample during the sampling process.

[0014] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0015] like Figure 1-3 As shown, a simple hydraulic oil sampling anti-pollution device comprises a sampling bottle 1, the outer wall of the top of the sampling bottle 1 is threadedly connected with a bottle cap 2, a one-way valve 3 is arranged at one end of the top of the bottle cap 2, a connecting hose 4 is connected to the end of the one-way valve 3 away from the bottle cap 2, a connecting pipe 5 is arranged at the other end of the top of the bottle cap 2, a sealing cap 6 is sleeved on the outer wall of the connecting pipe 5, and the outer wall of the connecting pipe 5 is threadedly connected with the inner wall of the sealing cap 6, an insert tube 7 is inserted inside the connecting pipe 5, and a long cylindrical rubber pad 8 is inserted at the top end of the inner part of the insert tube 7 The outer wall of the long cylindrical rubber pad 8 is bonded to the inner wall of the insert tube 7, and a short cylindrical rubber pad 9 is inserted at the inner bottom end of the insert tube 7. The outer wall of the short cylindrical rubber pad 9 is bonded to the inner wall of the insert tube 7. A slot 10 is opened in the middle of the long cylindrical rubber pad 8 and the short cylindrical rubber pad 9, and the inner walls of the slot 10 are in a closed state of squeezed contact to ensure sealing. When the plug squeezes the slot 10, the contact closed state is expanded and opened, and the opened inner wall will fit the outer wall of the plug to achieve the effect of filtering and dust removal.

[0016] Working principle: When sampling, first determine whether the bottle cap 2 and the sampling bottle 1 are in a tightly connected relationship. If the connection is found to be unstable, the bottle cap 2 needs to be screwed to maintain a tight threaded connection with the sampling bottle 1, and the sealing cap 6 threadedly connected to the outer wall of the connecting tube 5 is removed. The hydraulic meter line plug of the hydraulic station sampling point is connected to the slit 10 cut on the long cylindrical rubber pad 8 and the short cylindrical rubber pad 9 in the plug tube 7. When the plug passes through the slit 10 on the long cylindrical rubber pad 8, the dust adhering to the outer wall can be isolated and blocked to prevent the dust from entering the interior of the sampling bottle 1 through the connecting tube 5 and infecting the sample. When it passes through the long cylindrical rubber pad 8 and then the slit 10 on the short cylindrical rubber pad 9, the dust on the outer surface of the plug can be filtered again to prevent some dust with strong adhesion from contacting the inner wall of the slit 10 on the long cylindrical rubber pad 8 and being brought in along with the insertion of the plug. The interior of the sampling bottle 1 plays a role of insurance. After the plug passes through the short cylindrical rubber pad 9, it is inserted into the internal top of the sampling bottle 1 and transports the sample into it. The sample enters the interior between the sampling bottle 1 and the bottle cap 2, and the air inside is discharged unidirectionally into the connecting hose 4 through the one-way valve 3, ensuring the pressure balance in the sampling bottle 1. At the same time, it is ensured that the sampling bottle 1 is always in a closed state during the sampling process, effectively avoiding the problem of pollutants being directly sampled in the environment and mixed into the oil sample bottle. After the sampling is completed, the plug and the insert tube 7 are directly taken out from the connecting tube 5, and then the sealing cap 6 is sleeved on the outer wall of the connecting tube 5 and threadedly connected thereto, and then transferred to the inspection place. The insert tube 7 is taken out to avoid the problem that when the plug is pulled out, the gap of the insert slit 10 becomes larger, causing the dust blocked between the long cylindrical rubber pad 8 and the short cylindrical rubber pad 9 to fall into the sampling bottle 1 from the enlarged gap.
