Description
Technical Field
The utility model relates to a valve casting field especially relates to a stainless steel valve precision casting.
Background
The valve is a control part in a fluid conveying system, has the functions of stopping, adjusting, guiding, preventing countercurrent, stabilizing pressure, shunting or overflowing, relieving pressure and the like, is used for a valve of a fluid control system, and is from a simplest stop valve to various valves used in a very complicated automatic control system, the variety and the specification of the valves are quite various, most of the valves are cast iron valves and stainless steel valves, the valves are also divided into castings and forgings, the surface structure of the forgings is fine, the surfaces of the castings are thick, the processing surfaces of the forgings are bright, the castings have holes such as molding shrinkage holes, sand holes, parting surfaces, pouring holes and the like, the outer surfaces are too coarse and not precise enough, but the forging process is quite complicated, compared with the castings which are formed simply, more financial resources are required to be consumed, and the valve castings can be normally produced under the condition of excessive economy in order to ensure the delicate appearance of the valve castings, therefore, it is highly desirable to develop a precision stainless steel valve casting that covers the holes created in the casting to ensure an aesthetically pleasing appearance while extending the useful life of the casting.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an overcome the foundry goods surface and have holes such as shaping shrinkage cavity, sand eye, fractal face, plug hole, the surface is too coarse, and is not accurate enough, but the forging process has very loaded down with trivial details, compares in comparatively simple fashioned foundry goods, need consume the shortcoming of bigger financial resources and materials, the to-be-solved technical problem of the utility model is to provide a hole that can cover the foundry goods production to guarantee pleasing to the eye stainless steel valve precision casting who prolongs foundry goods life simultaneously.
The utility model is achieved by the following concrete technical means:
a stainless steel valve precision casting comprises a casting body, a flange plate, a flange connecting hole, a connecting disc, a butt joint port and a precision layer; the top of the casting body is connected with a butt joint port; the connecting disc is fixedly connected to the outer wall of the butt joint port; the flange plate is fixedly connected to the bottom of the casting body and is communicated with the casting body; flange connecting holes are uniformly formed in the flange plate and the connecting disc; the outer surfaces of the casting body, the flange plate and the connecting disc are covered with precision layers.
Further, the precision layer comprises a stainless steel layer, an aluminum alloy coating, an anti-skid glue layer and a transparent covering film; the casting body, the flange plate and the connecting disc are all made of stainless steel layers; the outer wall of the stainless steel layer is plated with an aluminum alloy plating layer; the anti-skid glue layer covers the aluminum alloy plating layer; the transparent covering film covers the outer wall of the anti-skid glue layer.
Furthermore, a threaded hole is formed in the butt joint port.
Furthermore, the anti-slip glue layer is organic silica gel.
After the mold is filled and molded, the valve casting is composed of a plurality of components such as a flange plate, a connecting disc and a casting body, the valve casting is various in types and is not suitable for one example, and the common valve casting is taken as an example and passes through the flange plate. The connecting disc can be connected with various pipelines by flanges, the pipeline port is aligned with the butt joint port, and after a sealing ring and a flange pad are sleeved outside the connecting disc, bolts and the like are inserted into the flange plate and the flange connecting hole of the connecting disc for flange connection to achieve the effect of installation, compared with a valve forging piece, a common valve casting piece has forming shrinkage holes, sand holes, parting surfaces, pouring holes and the like, the outer surface is too rough and not precise enough, the ornamental performance is influenced, the holes such as the forming shrinkage holes, the sand holes, the parting surfaces and the pouring holes are easy to accumulate water, dust, insect nets and the like, the valve casting piece is not only unattractive, but also influences the use, is corroded by sea fog for a long time in a sea fog diffuse area, even if the 304 stainless steel with high texture is still very easy to rust, the common valve casting piece cannot use the 304 stainless steel with too high manufacturing cost, and the corrosion resistance of the common stainless, therefore, the valve casting is covered with a precision layer all the year round, the stainless steel layer in the precision layer is contacted with an aluminum alloy layer, the aluminum alloy layer has a bright light-reflecting outer wall, holes such as a molding shrinkage hole, a sand hole, a parting surface, a pouring hole and the like on the outer surface of the casting can be filled, the casting is more beautiful and bright, the holes are lost, the accumulation of water stain, dust and insect net can be avoided, after the aluminum alloy layer is plated, when the valve casting is installed in a pipeline, the aluminum alloy layer is scratched when the valve casting is in collision for a long time, the appearance is still influenced, if the valve casting is in violent collision, the aluminum alloy layer can be rubbed off, therefore, the outer wall of the aluminum alloy layer is covered with an anti-slip glue layer, the anti-slip glue layer is made of organic silica gel, the valve casting can be prevented from sliding when a worker installs the valve casting, even the landing produces the striking with the bottom surface and also can be cushioned by anti-skidding glue film, protection aluminum alloy layer and stainless steel layer, when just using simultaneously, anti-skidding glue film outer wall has covered the transparent cover membrane of one deck, can protect anti-skidding glue film, avoid being rubbed off, but long-time back of using, transparent cover membrane still can drop, but can prolong anti-skidding glue film's life greatly, thereby let accurate layer obtain comprehensive protection, and life's extension, and so the material cost on accurate layer is not high, can not influence too much whole cost.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model discloses reached and to have covered the hole that the foundry goods produced, in order to guarantee pleasing to the eye effect of prolonging foundry goods life simultaneously, ordinary valve foundry goods is compared with the valve forging, the surface is too coarse, it is not accurate enough, influence the sight, and the surface is coarse to have the hole to pile up ponding easily, dust, the worm's net etc. not only beautifully, still influence the use, in the area that the sea fog is diffused, ordinary stainless steel that receives the erosion of sea fog for a long time easily produces the rust spot, influence pleasing to the eye while, also shorten life, consequently, cover one deck precision layer outside the valve foundry goods, it is the aluminum alloy layer in the stainless steel layer contact in the precision layer, the aluminum alloy layer has bright reflection of light outer wall, can fill the shaping shrinkage cavity of foundry goods surface, sand eye, the fractal face, holes such as pouring hole, let the foundry goods more pleasing to the eye, more bright and more beautiful, simultaneously lose the hole can avoid water, Dust, the piling up of worm net, nevertheless plate the aluminium alloy layer after, with the valve foundry goods probably meet the circumstances such as collide with, lead to the aluminium alloy layer to receive the scratch, perhaps rub the aluminium alloy layer off even, consequently, aluminium alloy layer outer wall has covered one deck anti-skidding glue film, anti-skidding glue film is made by organic silica gel, cushion by anti-skidding glue film when making the valve foundry goods receive the striking, protection aluminium alloy layer and stainless steel layer, anti-skidding glue film outer wall has covered the transparent cover membrane of one deck, can protect anti-skidding glue film, avoid being scraped and rubbed off, and whole accurate layer cost is not high, can not improve whole valve foundry goods cost.
