Abstract
The utility model relates to a direct-acting inserted overflow valve. A spring 2 is arranged between a conical valve core 1 and a pressure regulating screw plug 3 in an inserted valve body 8; the vertical part of the front end of the conical valve core 1 corresponds to a column oil reservoir 7; the column oil reservoir 7 is communicated with an oil inlet 4; the horizontal part of the front end of the conical valve core 1 corresponds to an oil return hole 5; the periphery of the utmost front end of the conical valve core 1 is provided with a thrust ring belt 6; an oil through hole 9 is arranged on the conical valve core 1.
Description
The utility model relates to direct-acting type plug-in mounting relief valve technical field.
Though at present direct-acting type low pressure relief valve or the leading type medium and high pressure relief valve that uses can both satisfy the overflow performance, all exist complex structure, fabrication bring more cost high and can not with shortcoming such as other hydraulic parts plug-in mounting.
The purpose of this utility model is a kind of direct-acting type plug-in mounting relief valve of design, and poppet valve core was closed when the oil pressure that enters the cylindricality oil pocket from oil inlet hole when pressure oil acted on the thrust endless belt and produces thrust less than spring pressure; When its thrust during greater than spring pressure poppet valve core open overflow.
Realize like this during the utility model: between poppet valve core 1 in plug-in mounting valve body 8 and the pressure regulation screw plug 3 spring 2 is arranged, vertically locate corresponding cylindricality oil pocket 7 at poppet valve core 1 front end, cylindricality oil pocket 7 communicates with oil inlet hole 4, the corresponding spill port 5 at poppet valve core 1 front end level place, in the peripheral foremost design of poppet valve core 1 thrust endless belt 6 is arranged, oil through 9 is arranged on the poppet valve core 1.
The utility model has the advantages that: alternative existing senior middle school low pressure relief valve is realized generalization, and simple and practical, the simple processing cost of manufacturing process is low, both can use separately, but the plug-in mounting combination has versatility and adaptability are installed widely again.
Below in conjunction with accompanying drawing, the utility model is described further with embodiment:
This accompanying drawing is the utility model structural representation.
In the accompanying drawing: 1, poppet valve core, 2, spring, 3, the pressure regulation screw plug, 4, oil inlet hole, 5, spill port, 6, the thrust endless belt, 7, the cylindricality oil pocket, 8, the plug-in mounting valve body, 9, oil through.
When the hydraulic oil that enters from oil inlet hole 4 acted on thrust that thrust endless belt 6 produces less than spring 2 set pressures, poppet valve core 1 was closed; When the thrust of its generation during greater than spring 2 set pressures, pressure oil promotes thrust endless belt 6 opens poppet valve core 1, and pressure oil flows back to fuel tank through spill port 5.
