Needle Industrial Valves and needle valve, needle gate is to use multiple single ram block, horizontal piece put entry slot fold into a plane water retaining structure. Stop log on its own weight and water stop rubber water-stop to achieve. Generally composed of more than two pieces of ram composite. When the brake or opened, add or even a piece out, use frequency is low, but the overall light and not easy to change shape, even if idle for a long time before using, ensures water effect is good, no leaking. Each disc height, must be the shape of each are basically the same, each has a tongue and groove ( Or tongue-and-groove) , tongue and grooves with water sealing strip, so that we can piece together, reached the height of the need and basic not leak or ignorance of leaking. Each gate also has two TAB, easy to put down or removed. Gate slot with steel plate into [channel, and channel on the embedded steel plate welding to install. Rely on fold beam brake set on the spring and the effect of water pressure, water stop rubber and gate slot fit closely after compression, waterproof effect is good.
