Description
Technical field
The utility model relates to a kind of valve seat, is specifically related to a kind of valve seat based on laser melting and coating process.
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, simultaneously on medium channel because of for a long time and medium contact, therefore also there is the problem by dielectric corrosion, in addition, also there is the problem of easily getting rusty 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 laser melting and coating process that effectively can improve usability and working life.
For achieving the above object, the utility model provides a kind of valve seat based on laser melting and coating process, 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, the outer surface of described valve seat body, the outer surface of medium channel and sealing surface are equipped with cobalt base alloy cladding layer, and described in the cobalt base alloy cladding layer be positioned on valve seat body outer surface be also provided with rust preventive coating outward, the described cobalt base alloy cladding layer be positioned on medium channel outer surface is also provided with the preserving timber bed of material outward, the described cobalt base alloy cladding layer be positioned on sealing surface is also provided with lubriation material coating outward.
The beneficial effects of the utility model are: adopt said structure, because the utility model is equipped with cobalt base alloy cladding layer on the outer surface of described valve seat body, the outer surface of medium channel and sealing surface, therefore can the overall usability of effective lifting valve base body.Also rust preventive coating is set outward at the described cobalt base alloy cladding layer be positioned on valve seat body outer surface simultaneously, then can effectively avoids valve seat body outer surface to occur getting rusty; At the described cobalt base alloy cladding layer be positioned on medium channel outer surface, the preserving timber bed of material is also set outward, then effectively can improves the corrosion resistance of medium channel; Also be provided with lubriation material coating outward at the described cobalt base alloy cladding layer be positioned on sealing surface, then effectively can improve the lubricity of valve seat body sealing surface, thus make valve seat body can realize rotary seal with flap or spheroid better to coordinate.In sum, arranged by said structure, the overall usability that effectively can improve valve seat body also extends the whole service life of valve seat body greatly.
The thickness that the utility model can be set to described cobalt base alloy cladding layer is further 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 described preserving timber bed of material preferred epoxy composite coating further, and its thickness is greater than 0.2mm.
The utility model also can be set to the preferred boron nitride material coating of described lubriation material coating further, and its thickness is greater than 0.2mm.
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
As Fig. 1, a kind of valve seat based on laser melting and coating process is given shown in 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, the outer surface 3 of described valve seat body, the outer surface of medium channel 1 and sealing surface 2 are equipped with cobalt base alloy cladding layer 4, and described in be positioned at that cobalt base alloy cladding layer 4 on valve seat body outer surface 3 is outer is also provided with rust preventive coating 5, the described cobalt base alloy cladding layer 4 be positioned on medium channel 1 outer surface is outer is also provided with the preserving timber bed of material 6, the described cobalt base alloy cladding layer 4 be positioned on sealing surface 2 is outer is also provided with lubriation material coating 7.The thickness of described cobalt base alloy cladding layer 4 is greater than 0.5mm.Described rust preventive coating 5 is rust proof paint preferably, and its thickness is greater than 0.2mm.The described preserving timber bed of material 6 preferred epoxy composite coating, and its thickness is greater than 0.2mm.Described lubriation material coating 7 is boron nitride material coating preferably, and its thickness is greater than 0.2mm.
Adopt said structure, because the utility model is equipped with cobalt base alloy cladding layer 4 on the outer surface 3 of described valve seat body, the outer surface of medium channel 1 and sealing surface 2, therefore can the overall usability of effective lifting valve base body.Rust preventive coating 5 is also set outside the described cobalt base alloy cladding layer 4 be positioned on valve seat body outer surface 3 simultaneously, then can effectively avoids valve seat body outer surface 3 to occur getting rusty; The preserving timber bed of material 6 is also set outside the described cobalt base alloy cladding layer 4 be positioned on medium channel 1 outer surface, then effectively can improves the corrosion resistance of medium channel 1; Be positioned at that cobalt base alloy cladding layer 4 on sealing surface 2 is outer is also provided with lubriation material coating 6 described, then effectively can improve the lubricity of valve seat body sealing surface 2, thus make valve seat body can realize rotary seal with flap or spheroid better to coordinate.In sum, arranged by said structure, the overall usability that effectively can improve valve seat body also extends the whole service life of valve seat body greatly.
