A zero-cold water functional waterway with scalable vertical water supply

Abstract

The invention discloses a zero-cold water function water circuit with scalable vertical water replenishment, comprising a casing, wherein the casing comprises a water replenishment channel, a water replenishment control channel, a water inlet channel, a water outlet channel, a hot water channel and a water pump interface, a hot water channel and a water pump The interface is connected, the water inlet channel and the water outlet channel are connected through the water channel, the water supplement channel is connected to the water channel, and the water supplement control channel is equipped with a water supplement device. The water supplement device can connect or separate the water supplement channel and the hot water channel. The zero-cold water function water channel of the present invention is scalable and vertical for water supply, so that the valve body and the bottom plate are truly completely sealed, the flexibility of water supply is improved, the operation and replacement are convenient, and the anti-recoil design of the flow sensor ensures that the flow sensor can always work accurately. .

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
