Ball floating valve device and water tank device

Abstract

The invention discloses a ball floating valve device and a water tank device. The ball floating valve device comprises a valve part, a floater and a rod part, wherein the valve part comprises a water inlet, a water outlet, a first chamber communicating with the water inlet, a second chamber communicating with the water outlet, a first valve element mechanism used for controlling connection and disconnection of the first chamber and the second chamber, a third chamber directly or indirectly communicating with the water inlet to enable the first chamber is separated from the second chamber by applying pressure to the first valve element mechanism through pressure water guided from the water inlet, a control flow channel connected between the water outlet and the third chamber, and a second valve element mechanism used for controlling connection and disconnection of the control flow channel, wherein the floater drives the second valve element mechanism through the rod part so as to control connection and disconnection of the control flow channel.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to a float valve device and a water tank device. Background technique [0002] In the field of water purification technology, a float valve is usually used to control the liquid level of the water tank, so that the external water source can simultaneously supply water to the water tank while taking water from the water tank, so that a certain amount of water is always stored in the water tank. [0003] Float valves in the prior art generally include a float for sensing the liquid level in the water tank and a valve component for controlling water supply to the water tank; the valve component has a water inlet, a water outlet and a spool positioned between the water inlet and the water outlet, and the water inlet Connected to the water source; the float is linked with the spool in the valve part by a rod part (such as a connecting rod). The water port is connected, so tha...

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned float valve can control the water source to supply water to the water tank, however, because the float of the above-mentioned float valve directly controls the valve core through the rod component, this leads to the following defects: the amount of water entering is difficult to obtain precise control

[0007] The rod part makes the port of the control flow channel open, and part of the water of the water source will also flow out from the port, and this requires that the valve part as a whole needs to be assembled inside the water tank, which is bound to be unfavorable for cleaning the valve part

[0008] In addition, in order to reduce the flow of water flowing out from the port of the control flow channel, the port is usually set smaller, and because the port is located above the liquid level, it is easy to contact with air, which is easy to foul the port, thereby increasing the possibility of port blockage
