Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As shown in Figure 1, 2, 3, combine the specific embodiment of resistance to erosion slurry valve for the utility model multi-angle.Embodiment comprises left valve barrel 1, right valve barrel 2, valve seat 3 and flap 4, the flanged surface excircle that left valve barrel 1 is relative with right valve barrel 2 is provided with the mounting hole 12 of multiple cooperations, install and connect left valve barrel 1 and right valve barrel 2 through the link of mounting hole 12, the rotatable installation of flanged surface makes 12 alignment of different mounting holes coordinate.Left valve barrel 1 and right valve barrel 2 can adopt different angle assemblings, for example 180 °, 135 °, 90 ° etc.Install and is connected both axis afterwards and is the angle of 180 ° with right valve barrel 2 if Fig. 1 is left valve barrel 1, flow passage structure is in line when assembling, flow resistance is little, can reduce to greatest extent the pressure drop of valve front and back, fluid changes flow direction hardly, ensure can not produce larger local scour energy in aluminium oxide operating mode alkaline mud and the particle media process of circulation, meet the circulation of mud and particle media.Install and is connected both axis afterwards and is the angle of 90 ° with right valve barrel 2 if Fig. 2 is left valve barrel 1, when assembling, become angie type flow passage structure, the twice that meets valve lateral length simultaneously and be longitudinal length is that valve two flange center's lines and end face of flange perpendicular distance are twice, facilitate the layout design of pipe-line system, and can replace angle valve to use.
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 cylindrical body 41 and taper 42, cylindrical body 41 is arranged on the more close annular boss 31 in front of relative taper 42 on flap 4, in slurry valve opening-closing process, the resistance to erosion passage 5 that annular boss 31 and cylindrical body 41, taper 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 annular boss 31 of valve seat 3 and the cylindrical body 41 of flap 4, taper 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, the quantity of mounting hole 12 be four or four doubly several, and in a circumferential direction evenly arrange.The design of above-mentioned mounting hole 12 has ensured that the selection installation of left and right valve body multi-angle coordinates, and accurate positioning is firm, is convenient to processing.
As the improved embodiment of one, 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 42 of flap 4.Taper 42 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 42 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 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 cylindrical body 41 and annular boss 31, form gap.The sealing surface that flap 4 head design become cylindrical body 41 and taper 42 to combine; in the time of valve opening and closing; Spielpassung between the cylindrical body 41 of flap 4 and the annular boss 31 of valve seat 3; 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, also include valve rod 6, flap 4 has groove 43, insert in the groove 43 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 43 connects and fixes with flap 4, valve rod 6, stretches out the part of groove 43 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 43, 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.
