Problems solved by technology

There are also some improved three-way valves that have the function of water cut-off, but due to their structural design, the on-off of the three-way valve is greatly affected by the change of raw water pressure, and it is easy to generate large vibration when switching between on and off states

Embodiment 1

[0022] Such as figure 1 As shown, the water cut-off three-way valve of the present embodiment includes a three-way seat 06, and the three-way seat 06 is provided with a water inlet 01, a water outlet one 16, and a water outlet two 24. The water outlet 01, the water outlet two 24 are connected with the original water chamber one 31, and the waterway where the original water chamber one 31 is connected with the water outlet one 16 is provided with a water cut-off assembly, and the tee seat 06 is also provided with a connection with the original water chamber one 31. The original water chamber two 29, the negative pressure chamber 07 connected with the water outlet one 16, the waterway connected by the original water chamber two 29 and the negative pressure chamber 07 has a sealing water port formed by the three-way seat body, and the water cut-off assembly includes a pressure sensitive Diaphragm 1 09, control rod 14, return spring 17, inner lining collar 18, fastening connecting...

Embodiment 2

[0024] On the basis of Embodiment 1, the cavity formed between the vent cover 08 and the pressure-sensitive diaphragm-09 forms an air cavity 30, and the vent cover 08 is provided with openings, and the air cavity 30 communicates with the outside world through the openings. The atmosphere communicates.

Embodiment 3

[0026] On the basis of Embodiment 1 or Embodiment 2, a filter screen frame 27 is provided in the raw water cavity, and the cavity in the filter screen frame 27 forms a filtered water cavity 25, and the water path and water inlet outside the filtered water cavity 25 01. The water outlet 2 24 is connected, and the filtered water chamber 25 is connected to the raw water chamber 2 29; one end of the filter frame 27 is provided with a filter handle 28, and the other end passes between the sealing ring 23 and the three-way valve body Sealed articulation.

Abstract

The invention discloses a water shutoff three-way valve and a water purifier system with the water shutoff three-way valve. The water shutoff three-way valve comprises a three-way seat, and the three-way seat is provided with a water inlet, a first water outlet and a second water outlet. A first raw water cavity is formed in the three-way seat. The water inlet and the second water outlet communicate with the first raw water cavity. The water channel communicating with the first raw water cavity and the first water outlet is provided with a water shutoff assembly. A second raw water cavity communicating with the first raw water cavity and a negative pressure cavity communicating with the first water outlet are further arranged in the three-way cavity. The water channel communicating with the second raw water cavity and the negative pressure cavity is provided with a water shutoff opening formed by the three-way seat body. The water shutoff three-way valve is not influenced by raw waterpressure change and can well solve the shake problem generated during switching in the opening state and the shutoff state.

Description

technical field [0001] The invention relates to a water cut-off three-way valve and a pure water machine system composed of the same. Background technique [0002] With the development of the economy, the situation of water resources has deteriorated in many places. The shortage and pollution of water resources have become more and more serious, and the problem of drinking water safety for urban residents has become prominent. Aiming at the secondary pollution of tap water in cities and the persistent presence of harmful substances in tap water due to source water pollution, more and more household water purifiers with reverse osmosis membrane as the core filter unit have entered thousands of households. The existing household pure water machine uses the reverse osmosis membrane as the core filter unit. After multi-stage pretreatment and pressurization of tap water, it enters the reverse osmosis membrane unit. The pure water produced can fully meet the domestic drinking wate...
