Pipeline ball valve door classification and USES
Ball ball valve door is with circular channels as open-close part, with the valve rod rotation realize on-off movement. ball valve door, is 90 degrees of rotation movement, the cock body for a sphere, a round hole or tunnel through its axis. Ball valve in the line is mainly used to do door stop, distribution, and change the flow direction of medium, it just has to rotate 90 degrees of operating and small rotational torque can be closed tightly. Ball valve door can be divided into: the fixed ball ball valve floating ball valve door, door, v-shaped ball valve door, discharge ball valve door, resistance to sulfur ball valve door, plastic ball valve door, the door card set of ball valves, welding ball valve door, air ball valve door, one-piece ball valve door, the door type ball valve, silk spiking, through ball valve door, three-way ball valve valve door, cross ball valve door, the door insulation ball valve, ball valve, pipeline ball valve door, rail cant ball valve door, anticorrosive ball valve door, etc. Common ball valve door main standards, specifications, and parameters: 1, the ball valve gate pressure rating: PN1. 0 - 32. 0MPa、150LB- 900LB、JIS10- 20 k 2, nominal size ball valve door: DN6 - DN800 1/4" - - - - - - 36' 3, ball valve door thread standard: G thread, mid-december, thread, such as NPT thread, BSPT thread 4, ball valve door connection mode: flange, butt welding, thread, socket welding, welding, such as card sets of 5, ball valve, gate applicable temperature: - 196℃- 0 ℃ 6 0 ℃ ~ 540 ℃, the ball valve gate drive mode: manual, worm gear and worm drive, pneumatic, electric, hydraulic, pneumatic, hydraulic linkage, electro-hydraulic linkage 7, the valve body material: WCB, ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mo2Ti, CF8, 304). 、CF3( 304L) 、CF8M( 316). 、CF3M ( 316 l) , chrome molybdenum steel towers ball valve gate doors can choose according to use the medium material, can be respectively suitable for water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea, and other media.
