A, use and performance specification
Q41 type ball valve is suitable for the small caliber pipeline, all kinds of pressure,temperature and medium to connect or disconnect the line media control the opening and closing device; by medium pressure will be pressed in the seat on the ball outlet,the use of pressure and diameter are subject to certain restrictions. Adopt 90 DEGtransmission, so the switch is convenient and rapid, can carry out fast opening and closing
Two, the operating principle and structure
1, ball valve channel is smooth and easy to sweep line pipe cleaning, can deliver the slurry and solid particle medium
2, using PTFE (Teflon) materials such as sealing, with good lubrication and elasticity,and the sphere of friction coefficient of small, long service life
3, rapid opening and closing, opening and closing when the ball is rotated 90 degrees, convenient and quick
4 ball valve fluid resistance small, open channel, the channel of the valve body andball connecting pipeline section area and equal, a straight line figured, medium flow through the valve, the equivalent through a section of straight pipe, valve in various types of valves in the fluid of least resistance
5, configured with manual, worm gear drive, pneumatic, electric (explosion-proof) can realize the remote automatic control, can meet a variety of conditions of the user's request
