Abstract
The utility model provides a fast overflow valve comprising a valve body, an oil passing tank arranged in the valve body and a valve rod arranged in the oil passing tank. The oil passing tank comprises a first oil passing tank body and a second oil passing tank body communicated with the first oil passing tank body. A first spring is arranged in the first oil passing tank body, a second spring is arranged in the second oil passing tank body, and a third oil passing tank body communicating the first oil passing tank body and the second oil passing tank body is arranged between the first oil passing tank body and the second oil passing tank body. The fast overflow valve is compact in structure, convenient to operate, good in stabilizing effect, high in unloading efficiency and long in component service life.
Description
Technical field
The utility model is specifically related to quick relief valve.
Background technique
relief valve can be kept the valve inlet pressure and be bordering on constant, the pressure controlled valve that in system, unnecessary fluid refluxes by this valve, mainly play level pressure overflow effect in hydraulic equipment, voltage stabilizing, system unloaded and safety protection effect, relief valve is connected on oil circuit, relief valve produces back pressure, the moving element stationarity increases, be connected in series the solenoid valve of the small flow that overflows at the remote control mouth of relief valve, when electromagnet is switched on, the remote control mouth of relief valve leads to fuel tank, oil hydraulic pump off-load this moment, and during actual operation, in overflow, off-load, can not reach working efficiency and the quality wanted in the voltage stabilizing process, thereby affect the working life of element.
Summary of the invention
Technical problem to be solved in the utility model is to provide quick relief valve, and not only compact structure, easy to operate, and voltage regulation result is good, and off-load efficient is higher, the long service life of element.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: quick relief valve, comprise valve body, be located at the interior logical oil groove of valve body, be located at the valve rod in logical oil groove, described logical oil groove comprises the first logical oil groove, the second logical oil groove that is communicated with the first logical oil groove, be provided with the first spring in the described first logical oil groove, be provided with the second spring in the described second logical oil groove, be provided with the threeway oil groove that is interconnected between the described first logical oil groove and the second logical oil groove.
As preferably, the described first logical oil groove both sides are provided with the first U-groove bevel that is communicated with the first logical oil groove, and this structure the first logical oil groove both sides are provided with first and lead to the first U-groove bevel that oil groove is communicated with, and structure is more reasonable, and handling safety is reliable.
As preferably, the described first logical oil groove both sides also are provided with the second U-groove bevel that is communicated with the threeway oil groove, and this structure the first logical oil groove both sides also are provided with the second U-groove bevel that is communicated with the threeway oil groove, the safety reliability when further raising operates.
As preferably, described valve end is provided with the axle sleeve for fixed valve body, and the axle sleeve of this structure valve end is strengthened the stability of valve body structure, guarantees fluid proper flow in oil groove, avoids the leakage of fluid.
As preferably, described valve body adopts the setting of inverted " L " structure, and this structure valve body adopts inverted " L " structure, and is rational in infrastructure, makes fairly simplely, and cost compare is low.
Beneficial effect:
The utility model adopts technique scheme that quick relief valve is provided, and not only compact structure, easy to operate, and voltage regulation result is good, and off-load efficient is higher, the long service life of element.
