Floor drain with trap check valve
The invention relates to a floor drain with a trap check valve, which is applied to the field of building water supply and drainage. A tipping bucket type trap and a check valve are adopted, so that the device has the functions of automatically swinging to discharge water and supplement air downwards, mechanical sealing and water sealing, the drainage flow is large, the self-cleaning capability is strong, the device is difficult to block, the mechanical sealing and the water sealing formed after drainage are always effective, the harm of gas and insects in a sewer is avoided, the sewage is prevented from returning and overflowing, and the air is supplemented downwards when a drainage pipe of the device has negative pressure. Wherein the microminiature tipping bucket type trap and check valve, the national standard DN75 floor drain body and the grate form the national standard DN75 microminiature floor drain with the trap and check valve, and the national standard DN75 microminiature floor drain with the trap and check valve and the derived floor drain thereof are diversified in form, attractive and practical and can be repaired inside and outside. A floor drain which adopts a connector grate and is provided with a trap check valve, washing equipment which is not provided with a trap and a hose form a drainage system which shares a tipping bucket type trap, a check valve and an appliance drainage pipe, the problems that a water seal is dried up due to the fact that water is not drained frequently on the ground are solved, and cost is reduced.
本发明一种兼有存水弯止回阀的地漏，应用于建筑给排水领域。其采用翻斗式存水弯兼止回阀而具有自主摆动向下排水和补气、机械密封和水封功能，排水流量大、自清能力强而难堵塞，始终有效的机械密封及排水后形成的水封、避免下水道气体和昆虫危害、防污水返溢、器具排水管有负压时向下补气。其中微小型翻斗式存水弯兼止回阀与国标DN75地漏本体及箅子构成形式多样、美观实用、内外兼修的国标DN75微小型兼有存水弯止回阀的地漏以及其衍生的地漏，而采用接口箅子的兼有存水弯止回阀的地漏和不设存水弯的盥洗设备、软管构成共享翻斗式存水弯兼止回阀及器具排水管的排水系统，破解包括水封因地面不经常排水而干涸在内的诸多难题，降低成本。
