Described valve seat liner sleeve pipe adopts tungsten carbide material integral body to make.
The end section of described spool be major part last, microcephaly under the inverted conical shape.
Described valve opening be big mouthful last, osculum under the inverted conical shape in hole body.
Described guide sleeve stretches in the valve pocket, and the tape edge, bottom of guide sleeve is a tip-angled shape.
Export department's inwall at valve body has some grades of wear-resistant liner rings, all offer through hole in every grade of wear-resistant liner ring, through hole splicing in all wear-resistant liner rings be big mouthful down, osculum is at the fluid output passage of last bell mouth shape, be provided with trim ring and fastening screw trip bolt in the bottom of valve body, some grades wear-resistant liner ring is fixedly mounted in the valve body by trim ring and fastening screw trip bolt.
Described wear-resistant liner ring at different levels is made by tungsten carbide material integral body.
The utility model has greatly prolonged the working life of valve seat, avoid the high-pressure medium erosion spool that flows through and caused the side direction of spool to shake, the tape edge, bottom of guide sleeve is that tip-angled shape can scrape the granulated garbage that is adsorbed on the spool, prevent spool face incrustation and avoid spool that granulated garbage is brought in the guide sleeve, prolong the working life of guide sleeve, some grades wear-resistant liner ring for change easily, safeguard valve seat is convenient and avoid valve seat and outlet between leakage.The utility model is highly suitable in the conveying of Heisui River, pulp water in the Coal Chemical Industry system and uses.
Description of drawings
Fig. 1 is an overall structure schematic representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure, the utility model mainly is made of parts such as double-screw bolt 1, nut 2, loam cake 3, guide sleeve 4, valve rod 5, valve seat 6, valve seat liner sleeve pipe 7, wear-resistant liner ring 8, through hole 9, fluid output path 10, trim ring 11, fastening screw trip bolt 12, hold-down grid 13, Gland 14, filler 15, Packing seat 16, spirotallic gasket 17, Graphite pad 18, valve body 19, spool 20 and valve openings 21.
This Heisui River protection against erosion high pressure angle valve, comprise valve body 19, valve seat 6, loam cake 3, valve rod 5 and spool 20, valve body 19 has valve pocket, in loam cake 3, be provided with the filler 15 that is used for sealed valve stem 5, the below of filler 15 has Packing seat 16, the top of filler 15 has Gland 14, Gland 14 tops have hold-down grid 13, hold-down grid 13 passes through double-screw bolt, nut is fastened on the loam cake 3, loam cake 3 is fixedly mounted on the valve body 19 by double-screw bolt 1 and nut 2, between loam cake 3 and valve body 19, has spirotallic gasket 17, valve seat 6 is fixedly mounted in the valve body 19, at valve body 19 internal fixation guide sleeve 4 is installed, and has Graphite pad 18 between guide sleeve 4 and valve body 19, slipper seal is equipped with valve rod 5 in loam cake 3, the bottom of valve rod 5 is installed with spool 20, and described spool 20 is with guide sleeve 4 and is slidingly connected, and is installed with valve seat liner sleeve pipe 7 at valve seat 6, have valve opening 21 in the valve seat liner sleeve pipe 7, described spool 20 is the grafting at intermittence with valve opening 21 and is sealed and matched.Described valve seat liner sleeve pipe 7 adopts tungsten carbide material integral body to make.Can avoid the too fast damage of valve seat 6 like this, prolong the working life of valve seat 6, after valve seat liner sleeve pipe 7 damages, can easily change.
