Problems solved by technology

In the application process of the hydraulic damper, the oil leakage of the hydraulic damper often occurs. Once the hydraulic damper leaks oil, it will pollute the environment on the one hand, and on the other hand, the hydraulic damper will lose its damping function and cannot work normally.

Abstract

The invention discloses a hydraulic damper with an external leakage prevention function. The hydraulic damper comprises a right pin head, a right end cover, an outer cylinder barrel, an auxiliary oiltank right piston, an inner cylinder barrel, a damper piston, a damper piston rod, a baffle ring, a floating valve seat, an auxiliary oil tank left piston, a left end cover, a left pin head, an auxiliary oil tank piston reset spring and a middle cylinder barrel. According to the hydraulic damper with the external leakage prevention function, through the innovative structural design, a double-layersealing device is arranged between the piston rod and the end cover of the hydraulic damper, an oil leakage groove is formed between the two layers of sealing devices, oil liquid is led out through related oil ways and enters a low-pressure auxiliary oil tank, the external leakage risk of the hydraulic damper is greatly reduced, reliable work of the hydraulic damper is guaranteed, and wide application prospects are realized.

Description

technical field [0001] The invention relates to a hydraulic damper, in particular to a hydraulic damper with the function of preventing external leakage, and belongs to the fields of machinery, hydraulic pressure, damping buffer, anti-seismic and the like. Background technique [0002] At present, hydraulic dampers have been widely used in the field of anti-seismic shock absorption. In the application process of the hydraulic damper, the oil leakage of the hydraulic damper often occurs. Once the hydraulic damper leaks oil, it will pollute the environment on the one hand, and on the other hand, the hydraulic damper will lose its damping function and cannot work normally. . There are two forms of leakage of hydraulic dampers: internal leakage and external leakage. In particular, external leakage needs to be strictly controlled. In some special occasions, external leakage of hydraulic dampers is strictly prohibited. External leakage of hydraulic cylinders generally exists in d...
