Description
Technical Field
The utility model relates to the technical field of fixtures, in particular to a laser cladding fixture for an eccentric butterfly valve seat.
Background
The valve can be used for controlling the flow of various types of fluids such as air, water, steam, various corrosive media, slurry, oil products, liquid metal, radioactive media and the like. The valve industry plays a very important role as an important link of equipment manufacturing industry in national economy development. In order to meet the use requirements of industrial applications such as high and low temperature, strong erosion, long service life and the like, a metal seal butterfly valve has been greatly developed. Along with the application of high-temperature-resistant, low-temperature-resistant, strong-corrosion-resistant and strong-erosion-resistant high-strength alloy materials in butterfly valves, the metal sealing butterfly valves are widely applied in the industrial fields of high and low temperature, strong erosion, long service life and the like.
As shown in figure 1, the center line of the inner hole conical surface of the valve seat and the center line of the outer circle of the valve seat form an included angle beta, so that the sealing surface of the valve seat is eccentrically conical, the sealing section of the butterfly valve becomes elliptical, and the shape of the sealing surface is also asymmetrical up and down. Because the sealing surface is in an inclined cone shape, the side which is separated into a larger part is pressed upwards towards the valve seat along the large inclined curved surface, and the side which is separated into a smaller part is pressed downwards towards the valve seat along the small inclined curved surface. The sealing between the sealing ring and the valve seat is realized by the compression of the contact surface instead of the elastic deformation of the valve seat, the friction is very small in the opening and closing process of the eccentric butterfly valve, and the closer the valve is along with the increase of the closing pressure.
In actual industrial production and use, a metal reinforced coating is usually prepared on a valve seat sealing eccentric conical surface, a surfacing process is mostly adopted in the traditional process, but the problems of deformation, defects, material waste and the like in the surfacing process gradually eliminate the problems, and the laser cladding process has been widely applied to the preparation of the valve sealing surface reinforced coating due to the wide material range, small thermal deformation, excellent cladding coating performance, long service life and other technologies, and a 1-2mm cladding coating is generally prepared on a substrate valve seat sealing surface, and cobalt-based alloy powder is selected, so that the cladding coating with high hardness, wear resistance, corrosion resistance and good high temperature performance is obtained.
In the processing process of preparing the reinforced coating by laser cladding, the processing mode is that the circumferential rotation mode of the valve seat is matched with the linear motion mode of the laser cladding head to finally form a spiral cladding surface, and because the central line of the eccentric conical surface and the central line of the outer circle of the valve seat form an included angle beta, if the outer circle of the valve seat is directly clamped to rotate, the rotation of the eccentric conical surface is irregular, and the reinforced coating processing is inconvenient.
Disclosure of Invention
