Problems solved by technology

[0002] The drain valve used for toilets in the existing market adopts a direct pressing structure, because its main components are the valve stem and spring inside the drain valve body, but because of the need for reset, the spring has a relatively large spring reaction force , causing consumers to press with greater force
Moreover, the position of pressing the valve stem is placed at the water outlet end of the drain valve, resulting in easy water leakage and inconvenient pressing angle.
Furthermore, the sealing part of the water outlet is made of soft materials: such as rubber, which is easy to age after a long time, resulting in seal failure and water leakage, which greatly affects the service life of the drain valve.

Abstract

The invention discloses a drain valve for a water closet. The drain valve comprises a valve body which is provided with a water intake cavity, wherein a valve element component is arranged in the water intake cavity; an end cover is connected to the valve body at the upper side of the valve element component; a compartment for preparing pressure is defined between the end cover and the valve element component; a going-through port, which communicates with the compartment, is arranged in the vale element component; a pressure relief hole is kept in the end cover; and a sealing pad, which is used for opening and closing the pressure relief hole, is arranged on the end cover. With the application of the drain valve, pressing force of consumers can be greatly reduced, so that the consumers canfeel comfortable in using the water closet.

Description

technical field [0001] The invention relates to a drain valve for a toilet. Background technique [0002] The drain valve used for toilets in the existing market adopts a direct pressing structure, because its main components are the valve stem and spring inside the drain valve body, but because of the need for reset, the spring has a relatively large spring reaction force , causing consumers to press with greater force. Moreover, the position for pressing the valve stem is placed on the water outlet end of the drain valve, resulting in easy water leakage and inconvenient pressing angles. Furthermore, the sealing part at the water outlet adopts soft materials: such as rubber, which is easy to age after a long time, resulting in sealing failure and water leakage, which greatly affects the service life of the drain valve. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the object of the present invention is to provide a drain va...
