Abstract
The invention discloses a high-temperature abrasive resistant ball valve with a fixed ball and a floating valve seat. The ball valve has a left valve body (1) and a right valve body (7) which form a stuffing box with the floating valve seat (2) respectively. The stuffing box is filled with stuffing (4) and a high-temperature resistant spring (3) is arranged between stuffing (4) so as to form stuffing seal (12). The two floating valve seat (2) is caused to reach floating and sealing requirements in the left valve body (1) or the right valve body (7) in virtue of recurrent force of the embedded high-temperature resistant stuffing (4), the high-temperature resistant spring (3) and the auxiliary seal spring (13). In respect of material selection, the ball valve is made of a high-temperature material. The ball valve is made from a new material and by a new process and has a spray welding sealing surface made of a nickel-based alloy and a chrome-based alloy, thus improving hardness of the sealing surface (up to HRC68-72) and reaching remarkable effect of abrasive resistance, corrosion resistance and erosion resistance.
