Abstract

The invention discloses a drain valve which comprises a button seat arranged on the upper end, a barrel body arranged in the middle and a base arranged at the bottom; a lifting pipe is arranged in the barrel body, and one side of the barrel body is also provided with an overflow pipe which is communicated with the base; the drain valve is also provided with a lever-type drain mechanism; the lever-type drain mechanism comprises a semi-drain mechanism and a full-drain mechanism; and the semi-drain mechanism and the full-drain mechanism are arranged inside and outside of the barrel body separately. The drain valve has the advantages of simple and reasonable structure, quite convenient installation and use, and can flexibly and greatly adjust the water drainage and save water resource. Because the product has small size and lower cost, and some structures are improved, the produce fault rate is lower, and the use of a user is easier.

Description

technical field [0001] The invention belongs to the field of drain valve structure of a flush water tank. technical background [0002] At present, the drain valves used in most toilet flushing tanks are relatively large in volume, resulting in a large volume of the flushing tank. Installing such a flushing tank in some places that do not require a large water tank is likely to cause waste of water resources, and this This kind of drain valve has higher manufacturing cost due to its larger volume. [0003] The utility model patent with Chinese Patent No. 03273233.3 discloses a cylindrical second gear drain valve, which is matched with the water inlet valve and installed in the water tank on the side of the seat, and will be used to control the semi-drainage, full-drainage, half-row floats and full-row The floats are designed in the same cylinder to make it compact and can be widely used in various low-tank seat-side tanks including narrower and smaller-volume seat-side tank...
