Water valve with a new structure
1. joystick only make the move without rotation, in order to reduce the resistance when the handwheel plus the way the ball rolling friction.
2. Connect the joystick and the stem is the connecting rod. This product is available in four standard lengths, according to the actual situation of the selection manipulation device: design using hand wheel and nuts together.
3. Valve: valve from the valve body, valve tongue, conical sealing rings and other components, the body is a right angle bend welding parts, conical sealing ring is the key part of the water distribution valve sealing performance is good or bad, for the whole cast, flange connection with the body, the tongue and the valve stem is articulated connection.
4. flange spool: As with Roadway and with the connecting pipe between the water valve. When the valve is closed, the sealing surface can only rely on media pressure to seal, that is, only the sealing surface of the medium pressure to ram pressure to the other side of the seat to ensure the sealing surface, which is self-sealing. Most of the valve is sealed by force, that is, when the valve is closed, to rely on external pressure to force the gate valve to ensure the tightness of the sealing surface.
Sluice gate with a linear motion with the valve stem, usually in the lift rod with trapezoidal thread, as well as through the valve at the top of the nut on the valve guides, the rotary motion into linear motion, which is the operating torque thrust into action.
