[0003] However, due to the high relative humidity in the pump room, the components are easily damaged in the pump room with high relative humidity for a long time. The valve cannot be opened and closed or the signal transmission fails; and, because the electric valve is in the state of power for a long time to achieve the purpose of use, and is in direct contact with the water pipe, it is easy to age the insulation and cause leakage danger in the environment with high humidity for a long time; at the same time, the electric valve The system structure of the valve is complicated, the requirements for installation and debugging are high, the reliability of the whole system is poor, and it is prone to failure, which cannot effectively ensure the anti-overflow of the pump room; in addition, the electric valve system needs frequent maintenance, and the price and cost are high

The invention discloses an overfall automatic shutoff valve device for a mechanical pump room, which comprises a valve switch control box, wherein the inside of the valve switch control box is provided with a valve switch locking device, a valve switch power set, and a first signal transmission device, a second signal transmission device and a third signal transmission device which are connected with the valve switch power set, a manually-operated open valve handle which is connected with the valve switch power set through the first signal transmission device, and a water level signal sensor which is connected with the valve switch locking device. The overfall automatic shutoff valve device for the mechanical pump room completely adopts the mechanical principle, has a simple and reliable structure, high safety performance, low failure rate and no leakage danger, does not require power supply during the whole process of automatic shutoff of the valve after overfall, is convenient to assemble, and does not need daily maintenance.
Description
technical field [0001] The invention relates to a pump room overflow automatic closing valve device, in particular to a mechanical pump room overflow automatic closing valve device utilizing the principles of buoyancy, lever, spring expansion force, gravity and the like. Background technique [0002] At present, the existing measures to prevent flooding accidents in the pump room are electric closing systems. The main principle is to collect overflow signals based on electric energy signals, start the motor after transmission through electric signal lines, and use electric energy to close the valves to achieve emergency shutdown of the main water inlet. the goal of. It is widely used in the living and fire water supply pump rooms (basement pump rooms) of various living and residential areas, factories and mines, hotels and other units. Due to the failure of the water inlet valve of the pool or other reasons, the sinking (basement) pump room overflows . [0003] However, du...
