Problems solved by technology

[0003] However, at the moment when the flushing is completed, the float drops, the bottom valve closes the opening of the valve seat, and at the same time, there is a suction force that quickly sucks the bottom valve to the valve seat, causing the valve seat to receive a great impact, which may cause the valve seat to be damaged. The damage of the water tank will reduce the sealing performance, and the water in the water tank will flow out continuously, resulting in a waste of water resources.

Embodiment Construction

[0025] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0026] A double-capacity drain valve, such as Figure 1-4 as well as Picture 10 As shown, it includes a valve seat 1 and a valve body 2. The valve seat 1 is in a sealed connection with the bottom opening of a water tank (not shown), the valve body 2 is carried on the valve seat 1, and the valve seat 1 is opened and closed through the valve body 2. When it is opened, the water in the water tank flows out from the opening, and when it is closed, the water tank stores water. The valve body 2 includes a cylinder 21, and the cylinder 21 includes a partition 212 with a through hole. The partition ...

Abstract

The invention discloses a bottom valve of a drain valve and the drain valve. The drain valve comprises a bottom valve base, baffles and a sealing ring, the sealing ring sleeves the bottom valve base,the baffles are uniformly arranged on the bottom valve base in the shape of a ring, and gaps exist between the adjacent baffles. The baffles are arranged on the bottom valve, the water flow velocity is lowered, noise generated by water flow is lowered, suction to the bottom valve is reduced, the bottom valve falling velocity is reduced, impact force of the bottom valve to the valve base is lowered, and meanwhile the noise is lowered.

Description

Technical field [0001] The invention relates to the field of drain valves, in particular to a bottom valve of a drain valve and a drain valve. Background technique [0002] In the prior art, the full tie rod is guided to flush water from the opening of the cylinder partition. Therefore, the partition separates the float cavity containing the float from the water storage tank, which is formed in the cylinder and located above the float cavity in the cylinder. When the water level drops below the storage tank, the annular gap formed between the outer surface of the full tie rod and the opening of the partition allows the flushing water in the storage tank to be discharged regularly. At the same time, the annular gap conditionally closes the space between the full tie rod and the opening of the partition plate, and also prevents the premature drop of the float in the float cavity. Only when the flushing water is completely discharged from the storage tank through the annular gap, ...
