Zero-cold-water functional waterway capable of realizing telescopic vertical water replenishing

Abstract

The invention discloses a zero-cold-water functional waterway capable of realizing telescopic vertical water replenishing, which comprises a shell, wherein the shell comprises a water supplementing channel, a water supplementing control channel, a water inlet channel, a water outlet channel, a hot water channel and a water pump connector, the hot water channel communicates with the water pump connector, the water inlet channel communicates with the water outlet channel through a water channel, and the water supplementing channel communicates with the water channel; the water supplementing control channel is provided with a water supplementing device which can communicate with or cut off the water supplementing channel and the hot water channel, and the water supplementing control channel is vertically arranged. According to the zero-cold-water functional waterway capable of realizing telescopic vertical water replenishing, the valve body and the bottom plate are truly completely sealed, so that the water supplementing flexibility is improved, operation and replacement are convenient, and a flow sensor can work accurately all the time through the anti-backflushing design of the flow sensor.

Description

technical field [0001] The invention relates to the technical field of water inlet valves for wall-hung boilers, in particular to a zero-cold water function waterway with scalable vertical water supply. Background technique [0002] At present, the water inlet valve used for wall-hung boilers has the following problems: [0003] 1. The water supply valve of the water inlet valve is installed at an inclination, and there is a risk of bumping and damage during transportation. The water supply operation is not easy to exert force, and the installation will interfere with the adjacent pipes. The most important thing is that the inclined design of the water supply The valve cannot meet the needs of today's fully premixed condensing wall-hung boilers. The main reason is that the fully pre-mixed condensing wall-hung boilers require strict sealing, and the valve body and bottom plate of the inclined design of the make-up valve cannot be designed for reliable sealing. [0004] 2. Th...

AI Technical Summary

Problems solved by technology

[0003] 1. The water supply valve of the water inlet valve is installed at an angle. There is a risk of bumping and damage during transportation. The valve cannot meet the needs of today's fully premixed condensing wall-hung boilers. The main reason is that fully premixed condensing wall-hung boilers require strict sealing, and the inclined design of the valve body and bottom plate of the replenishment valve cannot be designed for reliable sealing.

[0004] 2. The water inlet valve has no zero cold water function

[0005] 3. The water inlet valve has no filter and no one-way valve. When replenishing water, impurities will enter the circulating hot water channel and reduce the service life of the pump.

[0006] 4. The current limiting ring in the flow sensor is easy to fall off when the water flow recoils, and the disassembly and assembly of the current limiting ring is very troublesome

The normal water flow state is from bottom to top. When recoiling, both the current limiting ring 71 and the filter screen 7 may be washed down. Once the current limiting ring 71 shifts, the flow sensor is no longer accurate, and the current limiting ring 71 passes through O Ring assembly, disassembly is more troublesome
