Abstract
The utility model belongs to a subordinate device of a hydraulic cylinder, in particular relates to an air bleeding device of a single-acting telescopic sleeve-type hydraulic cylinder, which comprisesa multistage cylinder barrel arranged in and sleeved with the cylinder body, a coupling flange arranged on the top outer side of the multistage cylinder barrel, and a spacing element, a guiding element and a sealing element which are arranged between stages of the cylinder barrel, and an air bleeding valve connected on the top outer side of the final stage cylinder barrel. The utility model solves the problems of the prior art of creeping, disordered cylinders and the like, can easily eliminate the residual air in the system, and can avoid the serious consequences due to the uncoordinated movements of creeping, disordered cylinders and the like caused by the compressed air in the system.
Description
Affiliated technical field
The utility model belongs to the fixture of oil hydraulic cylinder, is meant a kind of means of deflation of single-action telescopic sleeve hydraulic cylinder especially.
Background technique
Market survey result widely shows in a large number; Liu Tong preposition straight-tube lifting cylinder performance is stable inadequately in the market, the repair rate height.Phenomenons such as most common failure is creeped, random cylinder.Have a strong impact on the reputation of homemade cylinder, dwindled the market atmosphere.Add the swift and violent expansion of external product, seriously restricting the development of China's oil cylinder industry, weakening the competitive ability of homemade cylinder greatly.
The model utility content
The purpose of this utility model is to provide a kind of means of deflation of single-action telescopic sleeve hydraulic cylinder, with solution creep, problem such as random cylinder.
Overall technology structure of the present utility model is:
The means of deflation of single-action telescopic sleeve hydraulic cylinder comprises and is located at the multistage cylinder barrel that cylinder body is interior and suit cooperates, and is arranged at the land of multistage cylinder barrel top outer, and is located at spacing member 4, guide member 5, sealing component 6 between the cylinder barrels at different levels; Cylinder barrel top outer at the final stage cylinder is connected with bleed valve.
Concrete technical construction of the present utility model also has:
Bleed valve comprises the vent hole that is opened in final stage cylinder top outer, is matched with the valve stifled 3 on the vent hole.
Comparatively optimized technical scheme is: valve stifled 3 adopts screw-thread fit with vent hole.
Get loose for preventing that valve is stifled, be provided with packing ring 2 between valve stifled 3 and the vent hole.
More optimized technical scheme is, offers exhaust passage 4 on the described valve stifled 3.
The obtained technological progress of the utility model is:
Oil cylinder is installed on the dumping car, and it is stifled to make it stretch out loosening its crown valve in back entirely, and at this moment the air that retains in the system such as oil cylinder and pipeline is discharged by outlet valve, and cut-off valve is stifled then, so repeatedly the residual gas that gets final product in the light removal system for 1-3 time.Avoid ruining serious consequences such as people's wound because of cars that incoordinate movement caused such as creeping of causing of pressurized gas in the system, random cylinders.
Description of drawings
Accompanying drawing of the present utility model has:
Fig. 1 is an overall structure schematic representation of the present utility model.
Fig. 2 is the A portion partial enlarged drawing of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further, but not as to qualification of the present utility model.
The integral body of present embodiment structure as shown, comprising the multistage cylinder barrel of being located in the cylinder body and suit cooperates, be arranged at the land of multistage cylinder barrel top outer, and be located at spacing member 4, guide member 5, sealing component 6 between the cylinder barrels at different levels; Cylinder barrel top outer at the final stage cylinder is connected with bleed valve.
Bleed valve comprises the vent hole that is opened in final stage cylinder top outer, is matched with the valve stifled 3 on the vent hole.
Valve stifled 3 adopts screw-thread fit with vent hole.Get loose for preventing that valve is stifled, be provided with packing ring 2 between valve stifled 3 and the vent hole.Offer T-shape exhaust passage 4 on the described valve stifled 3.
