Oil pan drain valve device

Abstract

The invention discloses an oil pan oil drain valve device used for engine oil testing. The oil pan oil drain valve device comprises a valve casing which is of an integrated structure and a valve seat which is arranged at one side of the valve casing and used for connecting an oil pan in a sealing mode. An oil drain port joint is inserted into the valve casing in a sealing mode. A valve part used for controlling an oil drain port to be opened and closed is placed in the valve casing. The oil drain port joint and the valve seat are arranged at the different sides of the valve casing. The valve casing is directly sealed with the oil pan, and the oil drain port joint is directly inserted into the valve casing, so that the number of butted sealing faces between all connecting devices at the oil drain end of a whole engine oil testing device is reduced from the overall structure. Due to the fact that the number of the sealing faces is reduced, the number of possible engine oil leakage points is also reduced, and the sealing property of the engine oil testing device is improved. By the adoption of the integrated structure, a connecting pipe is omitted, the condition that engine oil residues in the connecting pipe is avoided, and thus the engine oil amount can be tested more accurately.

Description

technical field [0001] The invention relates to the technical field of automobile engine manufacturing and testing, and more specifically relates to an oil pan oil drain valve device used for engine oil testing. Background technique [0002] In the field of automobile engine manufacturing and testing technology, it is often necessary to test the engine oil to obtain data on the durability of the engine oil, the average consumption of the engine oil, etc., so as to provide different types of engines with new oil under different usage conditions. Suitable solutions, such as: this technology can be extended to the replacement of new engine oil when the engine is maintained for 5,000 to 10,000 kilometers. [0003] In the engine oil test, the oil sampling and oil consumption test during the engine bench test are all carried out under the hot engine state. In a durability test, the oil sampling frequency can reach more than ten times on average; There are also special requirement...
