Fig. 1 is overall sectional drawing of the present utility model.
Fig. 2 is the part sectioned view at valve seat of the present utility model and flap place.
Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As shown in Figure 1, 2, be a kind of specific embodiment of the utility model resistance to erosion slurry valve.This embodiment comprises left valve barrel 1, right valve barrel 2, valve seat 3 and flap 4, left valve barrel 1 and right valve barrel 2 assemble setting by link, inner side between left valve barrel 1 and right valve barrel 2 arranges valve seat 3, valve seat 3 has annular boss 31, flap 4 has the first cylindrical body 41 and the second cylindrical body 42, the first cylindrical body 41 is arranged on the more close annular boss 31 in front of relative the second cylindrical body 42 on flap 4, the diameter of the first cylindrical body 41 is less than the diameter of the second cylindrical body 42, in slurry valve opening-closing process, annular boss 31 and the first cylindrical body 41, the resistance to erosion passage 5 that the second cylindrical body 42 Formation cross-sections are dihedral.In the time of valve opening and closing; medium is the most serious to washing away of valve body; the first cylindrical body 41 of the annular boss 31 of valve seat 3 and flap 4, the second cylindrical body 42 coordinate a resistance to erosion passage 5 that cross section is dihedral of formation; can change the flow direction of high-pressure medium; make the souring of high-pressure medium stream on valve seat 3; can not directly act on valve interior wall, protection valve inwall, plays good resistance to erosion effect.For reaching better resistance to erosion effect, the material of valve seat 3 can adopt built-up welding cobalt base hard alloy.
As the improved embodiment of one, between the first cylindrical body 41 and the second cylindrical body 42, be provided with taper 43, taper 43 is that the first cylindrical body 41 is to the second cylindrical body 42 transitional structures; The top edge of annular boss 31 forms sealing strip 32, in the time that slurry valve is closed, and sealing strip 32 cooperation that contacts with the taper 43 of flap 4.Taper 43 has the effect that mild change high-pressure medium flows to, and reduces the impact of medium to flap 4; The sealing surface of valve adopts the linear hard sealing means of tapering, taper 43 wider range of flap 4, sealing strip 32 on valve seat 3 is narrower, sealing strip 32 withstands on taper 43 places, both form the sealing configuration of linear sealing, as edge seal, good sealing effect, can effectively overcome that sealing surface scabs phenomenon and the puzzlement that cannot seal.When head the first cylindrical body 41 and valve seat 3 are closed, utilize the plane of head to push effect, can stop that larger particles shape medium is away from sealing surface, also can clean out the layer that scabs that invests valve seat 3 sealing surface edges simultaneously, make the linear sealing safety and reliability of tapering, play wear-resistant effect.
As the improved embodiment of one, in slurry valve opening-closing process, between the first cylindrical body 41 and annular boss 31, form gap.The sealing surface that flap 4 head design become the first cylindrical body 41 and taper 43 to combine; in the time of valve opening and closing; Spielpassung between the first cylindrical body 41 and the annular boss 31 of valve seat 3 of flap 4; can effectively play unhurried current decompression; when keying, reduce the pressure difference of sealing surface both sides, when keying, play the effect of protection sealing surface.
As the improved embodiment of one, the top of valve seat 3 is provided with arc inner wall 33, and arc inner wall 33 is connected with the upper surface of annular boss 31.Flow through along resistance to erosion passage 5 medium coming and wash away arc inner wall 33, the flow direction of the mild change medium of arc inner wall 33, reaches the effect that reduces medium impact force, improves the ability that is hit and the working life of valve seat 3.
As the improved embodiment of one, also include valve rod 6, flap 4 has groove 44, insert in the groove 44 of flap 4 one end of valve rod 6, between flap 4 and valve rod 6, be provided with flap sheath 7, the part that flap sheath 7 is positioned at groove 44 connects and fixes with flap 4, valve rod 6, stretches out the part of groove 44 and extends to the far-end of valve rod 6.Flap sheath 7 has improved flap 4 stability, in the time of valve opening and closing, the flap 4 of cut-off class valve is due to the souring of medium, easily there is the phenomenon swinging, flap sheath 7 has effectively extended the contact length between flap 4 and valve rod 6, make valve rod 6 more stable in groove 44, reduced the dancing of flap 4, the closed degree of flap 4 and valve seat 3 while having improved valve opening and closing.
As the improved embodiment of one, also include valve gap 8, valve gap 8 is arranged on the top of right valve barrel 2, is provided with valve rod protection neck 9 on valve gap 8, and valve rod 6 is set in valve rod protection neck 9.The length of lifting when the length of valve rod protection neck 9 equals valve rod 6 and opens and closes, the valve rod 6 that can effectively protect can not produce alumina scale on surface, valve rod 6 is opened and closed while contact with filler and protect filler be not subject to the alumina scale of valve rod 6 surperficial generations and wear and tear; Improve valve rod 6 stability simultaneously, solved the problem that the valve rod 6 of cut-off class valve easily shakes; While shaking due to common cut-off class valve, usually can there is roll mark phenomenon in valve gap 8 and valve rod 6, and the design of valve rod protection neck 9 has avoided valve rod 6 roll mark places directly to contact with filler, has improved the sealing of filler.
