Water inlet valve, a double water inlet water pipe, and a double drainage water tank

Abstract

The invention discloses a water inlet valve, a double water inlet water pipe, and a double drainage water tank. A decompression valve plate of the water inlet valve is arranged in a pressure cavity, a heightening screw rod is arranged on the decompression valve plate and penetrates out from a decompression port, a counterweight floating body is arranged on the heightening screw rod, the specific gravity of the counterweight floating body is slightly smaller than water, and the arranged weight can press the decompression valve plate downwards to get away from the decompression port; the double water inlet water pipe is provided with a tap water port and a valve port, as well as a recovery water port and a recovery water outlet; and the double drainage water tank is provided with two water falling ports, two sets of water drainage systems are mounted, one set is introduced to an underground sewage pipe, and the other set is connected with a recovery water port on a water tank of a toilet. The water inlet valve, the double water inlet water pipe, and the water tank can be combined to form a water tank water inlet system capable of recovering and utilizing waste water, and when waste water is added into the water tank and the water level rises, the buoyancy of the counterweight floating body is very small, so that the damage to a valve body is avoided.

Description

Technical field: [0001] The invention relates to a water inlet valve, double water inlet pipes and double drainage water tanks, and belongs to the field of sanitary ware and sanitary ware manufacturing. Background technique: [0002] 1. The existing water inlet valve is closed by the buoyancy of water. When the water level reaches the set position, the buoy drives the lever to close the valve. After the valve is closed, the buoy can no longer be raised. At this time, if washing water etc. flow into the water tank, the greater buoyancy will act on the lever and the valve through the buoy, which will easily damage the valve for a long time. Therefore, this valve is not suitable for water tanks that need to utilize recycled water. [0003] 2. The existing sink has only one set of sewage pipes, and only part of the daily washing wastewater is suitable for reuse for flushing the toilet, and some water that is too greasy or too dirty cannot be used for flushing the toilet. Simpl...

Problems solved by technology

[0003] 2. The existing sink has only one set of sewage pipes, and only part of the daily washing wastewater is suitable for reuse for flushing the toilet. Some water that is too greasy or too dirty cannot be used for flushing the toilet

Simply connecting the drain of the existing sink to the inlet of the toilet tank is obviously not applicable
