Abstract
The horizontal single way valve aims to be convenient for processing, stable in operation, long in durability, and controlled by high pressure hydraulic fluids. It comprises valve bodies and valve elements, with the valve body having inlet and outlet channels for fluids, valve base with holes in the middle inside the fluid inlet channel, the said valve base compressed and connected with the valve element through springs. The inner face of the said valve base is flat; the front end of the valve element is the corresponding flat surface of the valve base with the area of front end of the valve element bigger than the inner area of the central hole of the valve base having holes clad. The single way valve is used to control the fluid direction in hydraulic system.
Description
Technical field
The present invention relates to a kind of one-way valve, refer in particular to a kind of plane type one-way valve that is used for the control of liquid flow path direction.
Background technique
One-way valve has purposes widely in hydraulic system.Traditional one-way valve structures, its valve core adopts the sphere or the conical surface usually, as the liquid current control of high-pressure system the time, because liquid stream has the pressure height (usually in the characteristics of 25MPa～600MPa), frequency fast (reaching usually more than 120 times/minute), frequent opening and closing action between spool and the valve seat, the as easy as rolling off a log inaccurate or Line of contact of contraposition that causes between valve seat and the spool weares and teares, and makes the sealing instability between the runner aperture of spool and valve seat; Show that by experiment the one-way valve of ordinary construction is a spheric structure as spool, only have an appointment 50,000 times following working life at the high pressure of 200MPa, and taper valve core is good slightly, is about 7.5 ten thousand times, all have short deficiency in working life.And in case spool or its working stability of prooving of valve seat considerable influence are difficult to maintenance again or change the component that damage, the one-way valve that can only more renew causes user cost high.
Summary of the invention
The technical problem to be solved in the present invention provides the plane type one-way valve of a kind of easy to process, good operating stability, long service life.
Technological scheme of the present invention is: a kind of plane type one-way valve, comprise valve body and spool, valve body is provided with feed pathway and liquid outlet channel, be provided with the valve seat of middle part band through hole in the feed pathway inboard, valve seat and spool are by the spring crimping, the interior edge face of valve seat is the plane, the front-end face of spool is and the corresponding plane of valve seat, and the front-end face area of spool is greater than the interior edge face area of the middle part through hole of valve seat and cover through hole, wherein said spool front end is embedded with wear-resistant block, be embedded with wear-resisting body at valve seat, described valve body is made up of two-part, and by being threaded, valve seat is a cylindrical body between two-part, valve seat is fixed by the crimping of two-part valve body, is provided with the bulge loop with the valve seat crimping on valve body.
Wear-resistant block described in above-mentioned a kind of plane type one-way valve, wear-resisting body, with hardness height, the wherein a kind of of cubic boron nitride, Tungsten carbite, silicon carbide, polycrystalline diamond, silicon nitride ceramics, boron nitride ceramics, aluminium oxide ceramics or zirconia ceramics that wear resistance is good is good, can improve greatly its working life like this.
After the present invention adopts said structure,, in the working life that under same material, can improve one-way valve exponentially, reach 150,000 times following working life as high pressure at 200MPa by with changing plane crimping sealing between spool and the valve seat into; After further improving, by adopting materials such as cubic boron nitride, Tungsten carbite, silicon carbide, polycrystalline diamond, silicon nitride ceramics, boron nitride ceramics, aluminium oxide ceramics or zirconia ceramics, can reach the working life of one-way valve more than 1,000,000,000 times, significant to high pressure liquid stream control.
