Technical Field
The invention relates to the technical field of gate valves, in particular to a leakage-proof gate valve with a double partition valve plate.
Background
When the gate valve is closed, the sealing surface can be sealed only by medium pressure, namely, the sealing surface of the gate plate is pressed to the valve seat on the other side by the medium pressure to ensure the sealing of the sealing surface, namely, the gate valve is self-sealed. Most gate valves are forcedly sealed, that is, when the valve is closed, the gate plate is forced to press against the valve seat by external force to ensure the sealing performance of the sealing surface, and the gate plate of the gate valve moves linearly along with the valve rod, which is also called as a rising stem gate valve. Usually, the lifting rod is provided with trapezoidal threads, and the nut at the top end of the valve and the guide groove on the valve body change the rotary motion into linear motion, namely change the operation torque into operation thrust. When the valve is opened, when the lifting height of the gate plate is equal to 1 of the drift diameter of the valve: at 1 time, the passage of fluid is completely clear, but in operation, this position is not monitored. In actual use, the vertex of the valve rod is used as a mark, namely, the opening and closing position is used as the full opening position. To account for the occurrence of lock-up due to temperature changes, the valve is normally opened to the top position and then returned 1/2-1 times to assume the fully open valve position. The valve is called a rotary rod gate valve or a hidden rod gate valve, and in the closing process of the gate valve, the valve is usually rotated and does not move through manual operation to judge whether the valve is tightly closed or not, the operation sense is actually inaccurate, the thread part is rusted, or impurities appear in the valve body, and the situation that the valve is not tightly closed and the valve leaks can occur, so that a leakproof gate valve with a double-partition valve plate is provided to solve the problem.
