[0028] When port valve body 4 and center valve body 1 are connected by bolt, the end of elastic sealing ring 7 and the end of hard sealing ring 6 are tightly attached, and elastic sealing ring 7 is in compression state.It is more specific that by the end of elastic sealing ring 7 and hard sealing ring 6 tightly attached, in turn, the elastic force of elastic sealing ring 7 is pressed to hard sealing ring 6.

[0029] The section of hard sealing ring 6 is L-shaped structure, and the inner wall of hard sealing ring 6 is arc-shaped structure, and the inner wall of hard sealing ring 6 is attached to the surface of ball valve spool 3.It is more specific that by installation groove 5, hard sealing ring 6 of section L-shaped structure can be positioned and installed, and the inner wall of hard sealing ring 6 is arc-shaped and can be attached to the surface of ball valve spool 3, so that the slurry remaining on the surface of ball valve spool 3 can be scraped by hard sealing ring 6 when ball valve spool 3 rotates.

[0030] Center valve body 1 includes valve shell 101, and the end of valve shell 101 is provided with connecting flange port 102, and the opening of valve shell 101 is inserted with end cover 103, and the end of the opening of valve shell 101 and end cover 103 are threadedly inserted with screw rod 104 to fix end cover 103, and valve stem 2 is rotatably arranged with end cover 103.It is more specific that by screw rod 104, end cover 103 can be fixed on the opening of valve shell 101, and valve stem 2 can be positioned and installed through end cover 103.

[0031] The port valve body 4 includes a port pipe body 401 and connecting flanges 402 fixedly installed at both ends of the port pipe body 401. The port pipe body 401 is fitted to the connecting flange port 102 via the connecting flange 402 at one end and fixed with bolts. The inner wall of the port pipe body 401 is provided with a tapered channel 403. More specifically, the port pipe body 401 and the valve body 101 are fixedly connected by the connecting flange 402 and the connecting flange port 102, and bolts are used to compress and install the elastic sealing ring 7.
