Abstract
A kind of eccentric rotary regulating valve, comprise the spool of valve body and valve inner, spool is connected with valve rod, medium inlet place in valve body is provided with valve seat, sylphon seal is passed through between valve seat and valve body, spool is split-type structural, comprise valve core head and valve core, the surperficial perforate that valve core head fits with valve core, the female metal insert of band is inlaid in hole, the surface that valve core fits with valve core head has through hole, and screw screws in metal insert through through hole and valve core head is fixedly connected with valve core, and the material of valve core head is pottery.The beneficial effects of the utility model are: the Placement of valve core head and valve core effectively protects screw washing away from medium, make to connect more reliable, extend the working life of valve core head, reduce cost.
Description
Art
The utility model relates to a kind of modulating valve, particularly a kind of eccentric rotary regulating valve be applied in Coal Chemical Industry CWS system.
Background technique
The modulating valve applying working condition that Coal Chemical Industry CWS system is applied is harsh, and flowing medium is mainly the high coal slurry of solid content, Heisui River, pulp water and buck, containing strong corrosive media and solid particles such as chlorion, ammonia, sylvite, hydrogen sulfide or phosphoric acid.Existing camflex valve (see Fig. 1) is pile-up welding hard alloy on spool, and overlay cladding is thinner, at restriction place, flowing medium mixes hard particles flow at high speed, and have powerful kinetic energy, spool is easily etched, life-span is extremely short, and the working life of a deck valve only has four, 50 days; The mode that the camflex valve improved adopts valve core head to be connected with valve core by fastening piece, its fastening piece is exposed to side medium often, (see Fig. 2), after using a period of time, erosion corrosion through medium easily causes fastening piece to lose efficacy, thus causes spool to damage, and working life is short.
Model utility content
In order to overcome the above-mentioned shortcoming of existing eccentric rotary regulating valve, the utility model provides a kind of wear-resistant, resistance to erosion, long service life and the eccentric rotary regulating valve of convenient maintenance and replacement
The utility model solves the technological scheme that its technical problem adopts, a kind of eccentric rotary regulating valve, comprise the mangetic core assembly of valve body and valve inner, mangetic core assembly is connected with valve rod, medium inlet place in valve body is provided with valve seat, sylphon seal is passed through between valve seat and valve body, mangetic core assembly is fabricated structure, comprise valve core head and valve core, the surperficial perforate that valve core head fits with valve core, the female metal insert of band is inlaid in hole, the surface that valve core fits with valve core head has through hole, screw screws in metal insert through through hole and valve core head is fixedly connected with valve core, the material of valve core head is pottery.
The beneficial effects of the utility model are: mangetic core assembly is made up of valve core head and valve core two-part, the female metal insert of built-in band on valve core head, with through hole on valve core, screw screws in metal insert through through hole and valve core head is fixedly connected with valve core, this Placement effectively protects screw washing away from medium, make to connect more reliable, extend the working life of valve core head, reduce cost; The material of valve core head and valve seat is stupalith, preferred nanoscale zirconia, and this material has ultra-fine grain and high hardness, obdurability and excellent corrosion resistance, effectively extends valve whole service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art 1;
Fig. 2 is the structural representation of prior art 2;
Fig. 3 is the structural representation of embodiment.
In figure: 1. valve body; 2. valve rod; 3. valve core; 4. valve seat; 5. bellows; 6. valve core head; 7. metal insert; 8. screw.
Embodiment
As shown in Figure 3, a kind of eccentric rotary regulating valve, comprise the mangetic core assembly of valve body 1 and valve inner, mangetic core assembly is connected with valve rod 2, medium inlet place in valve body is provided with valve seat 4, sealed by bellows 5 between valve seat 4 and valve body 1, mangetic core assembly is fabricated structure, comprise valve core head 6 and valve core 3, the surperficial perforate that valve core head 6 fits with valve core 3, the female metal insert 7 of band is inlaid in hole, the surface that valve core 3 fits with valve core head 6 has through hole, screw 8 screws in metal insert 7 through through hole and valve core head 6 is fixedly connected with valve core 3, the material of valve core head 6 is pottery, this Placement effectively protects screw 8 washing away from medium, make connection more reliable, extend the working life of valve core head 6, reduce cost.
In order to extend the working life of eccentric rotary regulating valve further, valve body 1 inside surfacing cemented carbide, cemented carbide specifically can adopt nickel-base alloy, also can select other under Coal Chemical Industry operating mode, have cemented carbide compared with high wear resistance, decay resistance, and design hard alloy layer 3 ~ 5mm, hardness is up to more than HRC65.
Claims (1)
1. an eccentric rotary regulating valve, comprise the mangetic core assembly of valve body and valve inner, mangetic core assembly is connected with valve rod, medium inlet place in valve body is provided with valve seat, sylphon seal is passed through between described valve seat and valve body, it is characterized in that: described mangetic core assembly is fabricated structure, comprise valve core head and valve core, the surperficial perforate that described valve core head fits with valve core, the female metal insert of band is inlaid in hole, the surface that described valve core fits with valve core head has through hole, screw screws in described metal insert through described through hole and valve core head is fixedly connected with valve core, the material of described valve core head is nanoscale zirconia.
