Abstract
The utility model relates to a hard sealing ball valve sprayed and coated with wolfram carbide coatings, which consists of a left valve body, a ball body, a valve rod, a right valve seat, a butterfly spring, a right valve body, a filling press cover, a position limiting block, a handle and the like, wherein the left valve body, the ball body, the right valve seat, the butterfly spring and the right valve body are sequentially connected, the valve rod, the filling press cover, the position limiting block and the handle are sequentially connected, the lower end of the valve rod is inserted into a tongue groove arranged at the top end of the ball body, and a valve seat sealing seat is processed on the left valve body. Wolfram carbide (WC) is sprayed and coated in a supersonic flame way on the outer surface of the ball body and on medium passages of the left valve body, the ball body, the right valve seat and the right valve body, the Rockwell hardness reaches 68 to 73HRC, the wolfram carbide is also sprayed and coated on a valve seat of the left valve body and the sealing surface of the right valve seat, the Rockwell hardness reaches 63 to 68HRC, and the wolfram carbide is also sprayed and coated on an inner cavity of the right valve body, the lower end of the valve rod, an inner cavity of the right valve body and other surfaces of the right valve seat, and the Rockwell hardness reaches 58 to 63HRC. After the adoption of the technical scheme, the abrasion resistance and flushing resistance degree of surfaces of ball valve medium passages, sealing pairs and other components exposed in media can be improved, and the service life of the valve reaches 3 to 5 times of that of the original common hard sealing ball valve.
Description
Affiliated technical field
The utility model relates to and a kind ofly improves that medium channel surface and sealing pair surface and other exposed surface wear-resistant, anti-in medium washed away, the ball valve of corrosion-resistant degree, can adapt to the solid-liquid two-phase flow medium and the Korrosionsmedium of strong erosion.
Background technique
At present, known metal hard-sealing ball valve, the sealing surface of its sealing pair adopts hardening processes such as nitriding treatment or surfacing CoCrW cemented carbide, still can't resolve under the working condition of solid-liquid two-phase flow medium and Korrosionsmedium, not wear-resistant, not corrosion-resistant, its working life was short, 3 months～half a year.
Summary of the invention
In order to overcome existing metal hard-sealing ball valve under the working condition of solid-liquid two-phase flow medium and Korrosionsmedium, not anti-ly wash away, not corrosion-resistant, the problem that working life is short, the utility model provides a kind of sprayed wc coating hard seal ball valve, this ball valve can not only anti-ly under low temperature, low pressure condition wash away, corrosion-resistant, can also medium and high temperature (reaching 650 ℃), high pressure (〉=10.0MPa) anti-ly under the condition wash away, corrosion-resistant, reach 3～5 times of original common hard seal ball valve working life.
The technological scheme that its technical problem that solves the utility model adopts is: this sprayed wc coating hard seal ball valve is made up of left valve barrel, spheroid, valve rod, right valve seat, butterfly spring, right valve barrel, Gland, limiting stopper, handle etc., left valve barrel, spheroid, right valve seat, butterfly spring, right valve barrel connect successively, valve rod, Gland, limiting stopper, handle connect successively, the valve rod lower end is inserted in the tongue-and-groove on spheroid top, processes sealing surface of seat on the left valve barrel.Compare with the common metal hard seal ball valve, the utility model has mainly utilized supersonic flame sprayer, medium channel sprayed wc (WC) to outer surface of spheroid, medium channel and left valve barrel, right valve seat, right valve barrel, reach 68～73HRC, the sealing surface position of left valve barrel valve seat, right valve seat is sprayed wc also, reach 63～68HRC, left valve barrel inner chamber, valve rod lower end, right valve barrel inner chamber, other outer surface of right valve seat be sprayed wc also, reaches 58～63HRC.
The beneficial effects of the utility model are, have improved ball valve medium channel, sealing pair surface and other surface abrasion resistance that exposes in medium decreases, anti-degree of washing away, and valve reaches 3～5 times of original common hard seal ball valve working life.
