Self-locating high-sealing large-flow three-way valve

Abstract

The invention discloses a self-locating high-sealing large-flow three-way valve. The three-way valve comprises a shell, wherein the shell comprises a water inlet channel, a first water outlet channel,a second water outlet channel and a valve cavity, the first water outlet channel and the second water outlet channel communicates with the water inlet channel in a switching mode, a valve element ismounted in the valve cavity and comprises a motor base and a three-way framework, the shell, the motor base and the three-way framework are made of plastic materials, the lower end of the motor base extends downwards to form a motor base clamping head, a three-way framework clamping groove allowing the motor base clamping head to be mounted from the side face is formed in the upper end of the three-way framework, the motor base and the three-way framework are connected by inserting the motor base clamping head into the three-way framework clamping groove in a matched mode, and the motor base is connected with the shell through clamping screws. According to the three-way valve, self-locating during mounting can be conveniently realized through the motor base and the three-way framework.

Description

technical field [0001] The invention relates to the technical field of water outlet modules of wall-hung boilers, in particular to a three-way valve with self-positioning, high sealing and large flow. Background technique [0002] The three-way valve currently used for the water outlet module of the wall-hung boiler has the following problems: [0003] 1. The three-way valve made of plastic is inconvenient to process threads, and the reliability of the threaded connection is insufficient. The motor seat and the three-way frame are indirectly connected by working springs (the motor seat and the three-way frame are not connected), so that When taking off the motor seat and the tee frame, it is difficult to take off the motor seat and the tee frame together due to the stretching force of the working spring, which requires pushing it out at the bottom of the tee frame, which is inconvenient to disassemble. [0004] 2. The lower valve port of the three-way valve (that is, the va...

AI Technical Summary

Problems solved by technology

[0003] 1. The three-way valve made of plastic is inconvenient to process threads, and the reliability of the threaded connection is insufficient. The motor seat and the three-way frame are indirectly connected by working springs (the motor seat and the three-way frame are not connected), so that When removing the motor base and the tee frame, it is difficult to remove the motor base and the tee frame together due to the stretching force of the working spring, which requires pushing it out from the lower part of the tee frame, which is inconvenient to disassemble

[0004] 2. The lower valve port of the three-way valve (that is, the valve port connected to the water inlet channel and the floor heating pipeline) adopts a return spring, that is, the lower end of the lower sealing seat is against the return spring, and the return spring is located at the lower end of the lower valve port. The spring has a certain The length of the three-way valve (the spring also needs supporting parts), so that the overall height of the three-way valve cannot be made lower. When the lower valve port is opened, there is a return spring and matching supporting parts in the flow channel space, which will cause resistance when the water flows. , leading to greater water resistance, and sometimes whistling sound, low benefit

[0006] 4. The existing three-way valve adopts the bypass valve, and the bypass valve is installed by the wire, which is troublesome to disassemble.

[0007] 5. In the prior art, the bathroom water outlet channel and the bathroom water inlet channel are not directly connected, and the two are connected through a horizontal process hole, because the center distance between the bathroom water outlet channel and the bathroom water inlet channel is relatively large, and the bathroom water outlet channel is not connected when the shell is manufactured. It cannot be directly connected with the water inlet channel of the bathroom, and the process hole is blocked with a plug and a wire, and there is an additional hidden danger of leakage

The current three-way valve uses more plugs and wires, which increases the hidden danger of leakage points
