The gate valve is also called rotating rod gate valve (also known as dark rod wedge gate valve). The stem nut is arranged on the gate, and the hand wheel rotates to drive the stem to rotate, so that the gate is lifted, usually there is a trapezoidal thread at the bottom of the valve stem, through the screw thread at the bottom of the valve and the guide groove on the valve disc, the rotating motion becomes a straight motion, that is, the operating torque becomes the operating thrust. When the valve is opened, when the lift height of the gate is equal to 1:1 times the diameter of the valve, the channel of the fluid is completely unblocked, but this position can not be monitored during operation.
Overall coating: The gate adopts integral coating, and its good coverage performance and accurate geometric dimensions ensure reliable sealing and long life.
Light weight: The valve body is made of ductile iron, which is light in weight and easy to install.
Flat bottom valve seat: the bottom adopts the same flat bottom valve seat design as the water passenger, which does not produce debris siltation and the sealing is more reliable.
Corrosion resistance: the inner cavity is coated with non-toxic epoxy resin to prevent corrosion and rust, which can not only be used for raw drinking, but also can be used in sewage systems.
It can be widely used in tap water, sewage, construction, petroleum, chemical, food, medicine, textile, electric power, shipbuilding, metallurgy, energy system and other fluid pipelines as a regulating and interception device.
