Abstract
The utility model relates to heat radiator protection device in a kind of hydraulic oil system.Described protective gear is arranged between the oil inlet end of hydraulic oil radiator and oil outlet end; described protective gear comprises bypass valve pipeline; described bypass valve pipeline comprises aluminum pipe, pipe joint, bypass valve; described pipe joint is arranged on aluminum pipe; described one end connects oil inlet end; the other end connects oil outlet end, described pipe joint connecting bypass valve, the built-in spring of described bypass valve.The utility model structure is simple, raising oil circuit sealing, effective reduction radiator scrappage, reduction radiator oil pressure, cost of production are low, by passing in and out oily two ends connecting bypass control valve unit at hydraulic oil radiator, spring pressure makes the locking of bypass valve pipeline, when circulation oil pressure is greater than bypass valve cracking pressure, once oil inlet end pressure overcomes spring pressure, blocking device is opened, recycle oil enters the circulatory system through bypass valve pipeline without oil radiator, thus reduces circulatory system oil pressure.
Description
Technical field
The utility model relates to the higher hydraulic oil cooling system of a kind of oil pressure, particularly relates to heat radiator protection device in a kind of hydraulic oil system.
Background technique
When hydraulic oil cooling system is opened, radiator back pressure is often comparatively large, and too high oil pressure can often cause the loose pipeline of oil to damage because pressure-bearing is excessive, and then causes hydraulic oil radiator to be scrapped, and increases user cost.
Model utility content
The utility model in order to overcome the above problems provide a kind of structure simple, improve oil circuit sealing, effectively reduce radiator scrappage, reduce radiator oil pressure, heat radiator protection device in hydraulic oil system that cost of production is low.
The technical solution of the utility model is: described protective gear is arranged between the oil inlet end of hydraulic oil radiator and oil outlet end; described protective gear comprises bypass valve pipeline; described bypass valve pipeline comprises aluminum pipe, pipe joint, bypass valve; described pipe joint is arranged on aluminum pipe; described one end connects oil inlet end; the other end connects oil outlet end, described pipe joint connecting bypass valve, the built-in spring of described bypass valve.
The utility model structure is simple, raising oil circuit sealing, effective reduction radiator scrappage, reduction radiator oil pressure, cost of production are low, by passing in and out oily two ends connecting bypass control valve unit at hydraulic oil radiator, spring pressure makes the locking of bypass valve pipeline, when circulation oil pressure is greater than bypass valve cracking pressure, once oil inlet end pressure overcomes spring pressure, blocking device is opened, recycle oil enters the circulatory system through bypass valve pipeline without oil radiator, thus reduces circulatory system oil pressure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structure for amplifying schematic diagram of bypass valve pipeline in Fig. 1.
In figure, 1 is oil inlet end, and 2 is bypass valve pipelines, and 3 is oil outlet ends, and 4 is aluminum pipes, and 5 is pipe joints, and 6 is bypass valve.
Embodiment
Heat radiator protection device in hydraulic oil system, described protective gear is arranged between the oil inlet end 1 of hydraulic oil radiator and oil outlet end 3, described protective gear comprises bypass valve pipeline 2, described bypass valve pipeline 2 comprises aluminum pipe 4, pipe joint 5, bypass valve 6, described pipe joint 5 is arranged on aluminum pipe 4, described one end connects oil inlet end 1, the other end connects oil outlet end 3, described pipe joint 5 connecting bypass valve 6, the described built-in spring of bypass valve 6, by passing in and out oily two ends connecting bypass valve pipeline 2 at hydraulic oil radiator, spring pressure makes bypass valve pipeline 2 locking, when circulation oil pressure is greater than bypass valve 6 cracking pressure, once oil inlet end 1 pressure overcomes spring pressure, blocking device is opened, recycle oil enters the circulatory system through bypass valve pipeline 2 without oil radiator, thus reduce circulatory system oil pressure, recycle oil passes through from bypass valve pipeline 2.
