Description

TECHNICAL FIELD

[0001] The utility model relates to the valve field of intelligent house, concretely relates to a shunt valve. BACKGROUND

[0002] In modern industry and daily life, the demand for accurate control and distribution of water flow is increasing. The traditional shunt valve often has problems such as inconvenient operation and high cost when an electromagnetic valve is added to the front end, which cannot meet the requirements of complex application scenarios and efficient work.

[0003] With the continuous progress of technology and the improvement of automation level, various devices and systems have higher requirements for the flexibility, accuracy and reliability of water distribution. For example, in some industrial production processes, it is necessary to accurately distribute water flow to different production lines or process links to ensure the quality and efficiency of production. In the intelligent home system, it is also necessary to intelligently control the water supply in different areas according to the user's needs. However, the existing shunt valve has many limitations in realizing the switching linkage function. On the one hand, its mechanical structure is complex and prone to failure, with high maintenance cost; on the other hand, the traditional control method is not intelligent enough to effectively integrate and work with other devices.

[0004] For example, the Chinese utility model patent with application number 202220125908.5 (grant announcement number CN216789313U) discloses a water outlet device, which includes a tubular water inlet connector, a water inlet ball head, a receiving piece, a water passage static sheet, a dynamic sheet, a water outlet pipe body, a bubbler, a locking piece and a cylindrical shell. The water outlet device is provided with a first function water outlet path and a second function water outlet path. The water passage static sheet is provided with a first water flow channel and a second water flow channel. The dynamic sheet, the water outlet pipe body, the bubbler and the locking nut constitute a switching water outlet mechanism. The cylindrical shell as a rotary operating part can selectively produce circumferential rotary displacement to drive the switching water outlet mechanism to rotate, so that the first function water outlet path is connected with the first water flow channel and / or the second function water outlet path is connected with the second water flow channel. However, this utility model can only switch the flow channel and mix water, and cannot realize water distribution and cooperation with other devices.

[0005] In addition, the water pressure of general tap water is 0.8MPa. When testing the devices of the intelligent home system, a water pressure higher than that of tap water is often used, and the test water pressure can reach 1.6MPa. Under the conditions of high tap water pressure and test water pressure, the pressure bearing capacity of the device is often 0.3MPaAB. If it is directly connected with tap water, it needs to bear high pressure, and long-term high pressure bearing can easily cause the aging of the device, causing liquid leakage and damage, increasing the failure rate, and leading to the device cannot be used normally.
