Abstract
The utility model relates to an insertion manually-operated stop valve used in a hydraulic system to stop or baffle liquid flow. The utility model has a structure of a common stop valve, and an assembly and joint mode of a two-way cartridge valve. An A cavity and a B cavity are blocked by an O-shaped sealed ring, which has reliable seal performance. The liquid force of a valve core has complete equilibrium through a damping hole of the valve core and a valve core shoulder, and the operation is laborsaving. A valve cover and a valve seat are assembled into a whole to ensure the concentricity of the valve core and the valve seat. The assembly and joint dimension accords with that of the two-way cartridge valve in a German standard DIN 24342. The utility model has convenient assembly. After assembled, the insertion manually-operated stop valve can be inserted on an oil way block, and the integration degree of the hydraulic system is increased.
Description
The utility model is used for hydraulic system, and liquid stream is ended or throttling.
With reference to " mechanical design handbook " volume two ［ Chemical Industry Press ］ P437-P44 ］ middle YJF high-pressure stop valve and German standard DIN24342 two logical cartridge valves installation Conncetion cimension.
The purpose of this utility model: design a kind of easy for installationly, sealing is reliable, and rapid operation improves the novel cutoff valve of the integrated degree of hydraulic system.
The method that realizes is: based on YJF high-pressure stop valve structure.A, B chamber are intercepted by the O RunddichtringO.Make spool fluid power complete equilibrium by damping hole on the spool and spool land.Valve pocket and valve seat are assembled into one.Be installed in Conncetion cimension and meet German standard DIN24342 two logical cartridge valves installation Conncetion cimension.Plug-in type hand stop valve after the assembling is inserted on the manifold block.
Its advantage is: sealing is reliable, rapid operation, and spool and valve seat concentricity easily guarantee, and be easy for installation, with two to lead to cartridge valves interchangeable, can improve the integrated degree of hydraulic system.
