Abstract
The utility model relates to a large-flow quick liquid filling valve. A valve seat is connected with a valve body, a red copper sealing ring is arranged between the valve seat and the valve body, the valve seat is provided with an oil pressurizing port, the valve body is provided with an oil controlling port, a valve core is arranged in the valve body, a valve cover is connected with the valve body, an O-shaped sealing ring is arranged between the valve cover and the valve body, a guide rod passes through the valve cover and the valve core, a spring is sheathed on the guide rod, and an oil cover is connected with the valve seat. By using the large-flow quick liquid filling valve, the liquid filling speed is quick, the flow is large, the resistance is small, and the requirement of quickly filling liquid for a large oil pressure machine cylinder can be met; the performance is stable, the control is simple, and the action is flexible and stable; and the external arrangement is adopted, so that the installation and maintenance is convenient, the cost is low, and the manufacture is simple.
Description
Technical field
The utility model relates to a kind of hydraulic control unit that a kind of oil cylinder to oil hydraulic press carries out quick topping up.
Background technique
The master cylinder diameter of large-sized hydraulic press is bigger, and stroke is long, thereby its cylinder internal volume is bigger; Only depending on the high pressure oil pump fuel feeding during work is to be difficult to reach the required travel speed of oil hydraulic press; For making oil hydraulic press in use have a rational idle running to fall soon and the backhaul lifting speed, adopt liquid-filling valve that oil cylinder is carried out quick topping up and be absolutely necessary; At present, its structural type of liquid-filling valve of oil hydraulic press employing mostly is Normally closed type, poppet valve, dual spring structure.The valve port diameter of this valve is less, and is little by flow, and the topping up time is long, do not satisfy the needs of large-sized hydraulic press; Must first release just can open liquid-filling valve during backhaul, release control system complexity, the release time is long; This liquid-filling valve is contained in the bottom of oil cylinder, and valve body all is immersed in the fuel tank installation and maintenance difficulty.
Summary of the invention
The purpose of this utility model provides the quick liquid-filling valve of a kind of big flow, and its topping up speed is fast, and flow is big, and resistance is little, satisfies the requirement of the quick topping up of large-sized hydraulic press oil cylinder; Reliable performance, control is simple, flexible movements, stable; External, installation and maintenance are convenient; Cost is low, making is simple.
The big quick liquid-filling valve of flow, valve seat is connected with valve body, is provided with the red copper seal ring between valve seat and the valve body, and valve seat is provided with the pressurization hydraulic fluid port, and valve body is provided with control port; Spool is located at valve inner, and valve gap is connected with valve body, is provided with the O RunddichtringO between valve gap and the valve body, and guide rod passes valve gap and spool, and spring housing is on guide rod, and the oil cover is connected with valve seat.
The beneficial effects of the utility model, the big quick liquid-filling valve of flow, valve seat is connected with valve body, is provided with the red copper seal ring between valve seat and the valve body, and valve seat is provided with the pressurization hydraulic fluid port, and valve body is provided with control port; Spool is located at valve inner, and valve gap is connected with valve body, is provided with the O RunddichtringO between valve gap and the valve body, and guide rod passes valve gap and spool, and spring housing is on guide rod, and the oil cover is connected with valve seat; Its topping up speed is fast, and flow is big, and resistance is little, satisfies the requirement of the quick topping up of large-sized hydraulic press oil cylinder; Reliable performance, control is simple, flexible movements, stable; External, installation and maintenance are convenient; Cost is low, making is simple.
