Description
Technical field
The utility model relates to a kind of one-way valve, and more particularly, it relates to a kind of plane type one-way valve.
Background technique
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 pressure height, the fast characteristics of frequency, 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, and lack working life.For this reason, Chinese patent application CN200610123691.X (publication number CN1963272A, open day 2007.05.16) " a kind of plane type one-way valve " disclosed, by the surface of contact between valve seat and the spool being made into the plane contact sealing, can improve the working life of one-way valve widely, but this technological scheme is found in force, owing to adopt the plane contact sealing between valve seat and the spool, the flatness of two surface of contact and degree of finish are all very high, easily influence sealability in the use because of the fine particle between surface of contact or attachment, need make improvements, to reach better sealability.
The model utility content
The technical problems to be solved in the utility model is the above-mentioned deficiency at prior art, and the plane type one-way valve of a kind of long service life, good seal performance is provided.
The technical solution of the utility model is such: a kind of plane type one-way valve, comprise valve body and valve core, 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 valve core are by the spring crimping, the interior edge face of described valve seat is the plane, the front-end face of valve core is and the corresponding plane of valve seat, and the front-end face area of valve core is greater than the interior edge face area of the middle part through hole of valve seat and cover through hole, wherein, described valve core front end is arranged with seal rubber sleeve, and the exterior edge face of seal rubber sleeve slightly protrudes in the front end end face of valve core.
In the above-mentioned plane type one-way valve, described spool front end is embedded with wear-resistant block, and described valve seat is embedded with wear-resisting body; Described seal rubber sleeve is set in the wear-resistant block periphery; Wear-resistant block, 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.
In the above-mentioned plane type one-way valve, described valve body is made up of two-part, between two-part by being threaded; Described valve seat is a cylindrical body, and valve seat is fixed by the crimping of two-part valve body; Can be convenient for changing the spool and the valve seat of wearing and tearing like this.
In the above-mentioned plane type one-way valve, described valve body is provided with the bulge loop with the valve seat crimping; Can guarantee sealing and convenient processing between valve body and the valve seat like this, reduce the processing and the maintenance cost of spool and valve seat.
After the utility model adopts said structure, by at the sheathed seal rubber sleeve of spool front end, can strengthen the sealing effect between valve seat and the spool, even under the situation that has fine particle or attachment to exist between the surface of contact of valve seat and spool, also can guarantee the sealability between them.
Description of drawings
Below in conjunction with the embodiment in the accompanying drawing the utility model is described in further detail, but does not constitute any restriction of the present utility model.
Fig. 1 is the structural representation of a kind of specific embodiment of the utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is a decomposition texture schematic representation of the present utility model.
Among the figure: valve body 1, left valve barrel 11, right valve barrel 12, valve core 2, wear-resistant block 2a, feed pathway 3, liquid outlet channel 4, valve seat 5, through hole 5a, wear-resisting body 5b, spring 6, seal rubber sleeve 7, bulge loop 8.
Embodiment
Consult Fig. 1 to shown in Figure 3, plane type one-way valve of the present utility model, be straight check valve, comprise valve body 1 and valve core 2, valve body 1 is provided with level to the feed pathway 3 and the liquid outlet channel 4 that are communicated with, valve body 1 is made up of left valve barrel 11, right valve barrel 12 two-part, between left valve barrel 11, the right valve barrel 12 by being threaded; Crimping is fixed with the cylindrical valve seat 5 of middle part band through hole 5a between left valve barrel 11, right valve barrel 12, on left valve barrel 11, right valve barrel 12, be equipped with bulge loop 8 with valve seat 5 crimping, can directly the plane be processed on valve seat 5 both sides like this and gets final product, to reduce processing and maintenance expenses; Be embedded with cylindrical wear-resistant block 2a at spool 2 front ends, be embedded with the wear-resisting body 5b of pipe shape at valve seat 5 middle parts, wear-resistant block 2a, wear-resisting body 5b all adopt polycrystalline diamond manufacturing (also can adopt materials such as other superhard material such as cubic boron nitride, Tungsten carbite, silicon carbide, silicon nitride ceramics, boron nitride ceramics, aluminium oxide ceramics or zirconia ceramics); The wear-resistant block 2a front-end face area at valve core 2 middle parts is greater than the through hole 5a interior edge face area of the wear-resisting body 5b in valve seat 5 middle parts, and the front-end face of wear-resistant block 2a is corresponding with the interior edge face of wear-resisting body 5b, realizes plane crimping sealing by spring 6; Front end at wear-resistant block 2a is arranged with seal rubber sleeve 7, and the exterior edge face of seal rubber sleeve 7 slightly protrudes in the front end end face of wear-resistant block 2a, and seal rubber sleeve 7 plays the effect of auxiliary seal, can strengthen the sealing effect between valve seat 5 and the spool 2.
Said structure scheme of the present utility model, equally applicable to the right-angle type one-way valve, its similar.Concrete using method of the present utility model is identical with traditional one-way valve, but because the sealing surface of spool 2 and valve seat 5 is designed to the plane, adopt the made spool 2 and the valve seats 5 such as cubic boron nitride, Tungsten carbite, silicon carbide, polycrystalline diamond, silicon nitride ceramics, boron nitride ceramics, aluminium oxide ceramics or zirconium oxide class pottery of high hardness, high abrasion, solved traditional one-way valve and under high pressure or ultrahigh pressure, used deficiency unstable, that the life-span is short, prolonged the working life of one-way valve greatly; And, more can guarantee sealing effect by seal rubber sleeve being set at the spool front end, improve the stability of using.
