Abstract
The utility model discloses a kind of valve seat based on supersonic spray coating technique, comprise valve seat body, described valve seat body offers medium channel, one end of described medium channel is provided with and can forms with spheroid the sealing surface be sealed and matched, described sealing surface is coated with ceramic powder filled layer, tungsten carbide wear resistant layer and lubriation material coating from inside to outside successively, described medium channel is provided with the preserving timber bed of material, the outer surface of described valve seat body is provided with rust preventive coating, and described rust preventive coating is also coated with nonpolluting coating outward.By adopting said structure, effectively can extend the whole service life of valve seat and greatly improving its usability.
Description
Technical field
The utility model relates to a kind of valve seat, is specifically related to a kind of valve seat based on supersonic spray coating technique.
Background technique
Valve seat is component important in valve, valve seat is typically provided with medium channel, and one end of described medium channel is provided with and can forms with spheroid the sealing surface be sealed and matched, but in the prior art, often there is the problem of serious wear in sealing face, medium channel is simultaneously because of long-term and medium contact, therefore also there is the problem by dielectric corrosion, in addition, also there is the problem of easily getting rusty with easy adsorption fouling thing in the outer surface of valve seat body, and these above-mentioned problems all greatly can affect the usability of valve seat and cause greatly shorten the working life of valve seat.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of valve seat based on supersonic spray coating technique that effectively can improve usability and working life.
For achieving the above object, the utility model provides a kind of valve seat based on supersonic spray coating technique, comprise valve seat body, described valve seat body offers medium channel, one end of described medium channel is provided with and can forms with spheroid the sealing surface be sealed and matched, described sealing surface is coated with ceramic powder filled layer, tungsten carbide wear resistant layer and lubriation material coating from inside to outside successively, described medium channel is provided with the preserving timber bed of material, the outer surface of described valve seat body is provided with rust preventive coating, and described rust preventive coating is also coated with nonpolluting coating outward.
The beneficial effects of the utility model are: adopt said structure, due to described sealing surface being coated with ceramic powder filled layer from inside to outside successively, tungsten carbide wear resistant layer and lubriation material coating, therefore the wear-resisting property of valve seat body sealing surface can not only greatly be improved, and greatly can also increase the lubricity of sealing surface, thus make valve seat body can realize rotary seal with flap or spheroid better to coordinate, and the preserving timber bed of material is set on described medium channel, then effectively can improve the corrosion resistance of medium channel, in addition, the setting of described rust preventive coating, valve seat body outer surface can be effectively avoided to occur getting rusty, also nonpolluting coating is coated with outward at described rust preventive coating, valve seat body outer surface then can be effectively avoided to occur the problem of adsorption fouling thing.Simultaneously, described ceramic powder filled layer, tungsten carbide wear resistant layer, lubriation material coating, the preserving timber bed of material, rust preventive coating and nonpolluting coating all realize spraying by supersonic spray coating technique and arrange, and greatly can extend the whole service life of valve seat and effectively improve its usability after spraying.
The utility model can be set to the preferred boron nitride material coating of described lubriation material coating further, and its thickness is greater than 0.2mm.
The utility model also can be set to described preserving timber bed of material preferred epoxy composite coating further, and its thickness is greater than 0.5mm.
The utility model also can be set to the preferred rust proof paint of described rust preventive coating further, and its thickness is greater than 0.2mm.
The utility model also can be set to the preferred chlorinated rubber coating of described nonpolluting coating further, and its thickness is greater than 0.3 mm.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the I portion enlarged view of Fig. 1.
Embodiment
Give a kind of valve seat based on supersonic spray coating technique as shown in Figure 1, 2, comprise valve seat body, described valve seat body offers medium channel 1, one end of described medium channel 1 is provided with and can forms with spheroid the sealing surface 2 be sealed and matched, described sealing surface 2 is coated with ceramic powder filled layer 3, tungsten carbide wear resistant layer 4 and lubriation material coating 5 from inside to outside successively, described medium channel 1 is provided with the preserving timber bed of material 7, the outer surface of described valve seat body is provided with rust preventive coating 8, described rust preventive coating 8 is outer is also coated with nonpolluting coating 9.Described lubriation material coating 5 is boron nitride material coating preferably, and its thickness is greater than 0.2mm.The described preserving timber bed of material 7 preferred epoxy composite coating, and its thickness is greater than 0.5mm.Described rust preventive coating 8 is rust proof paint preferably, and its thickness is greater than 0.2mm.Described nonpolluting coating 9 is chlorinated rubber coating preferably, and its thickness is greater than 0.3 mm.
Adopt said structure, due to described sealing surface 2 being coated with ceramic powder filled layer 3 from inside to outside successively, tungsten carbide wear resistant layer 4 and lubriation material coating 5, therefore the wear-resisting property of valve seat body sealing surface 2 can not only greatly be improved, and greatly can also increase the lubricity of sealing surface 2, thus make valve seat body can realize rotary seal with flap or spheroid better to coordinate, and the preserving timber bed of material 7 is set at described medium channel 1, then effectively can improve the corrosion resistance of medium channel 1, in addition, the setting of described rust preventive coating 8, valve seat body outer surface can be effectively avoided to occur getting rusty, nonpolluting coating 9 is also coated with outside described rust preventive coating 8, valve seat body outer surface then can be effectively avoided to occur the problem of adsorption fouling thing.Simultaneously, described ceramic powder filled layer 3, tungsten carbide wear resistant layer 4, lubriation material coating 5, the preserving timber bed of material 7, rust preventive coating 8 and nonpolluting coating 9 all realize spraying by supersonic spray coating technique and arrange, and greatly can extend the whole service life of valve seat and effectively improve its usability after spraying.
