Description

Technical Field

[0001] The utility model relates to the technical field of intelligent water meter valves, in particular to an intelligent water meter valve driven by radio. Background Art

[0002] The remote transmission and remote control smart water meters commonly used in modern water services have two core functions. One is that they have a sufficiently long service life, which enables timely or scheduled remote collection and transmission of water flow information for seven or eight years or even longer. The other is that they can ensure stable and accurate remote control of the valve switch of the reduction motor during the entire life of the water meter, and realize remote flow control at any time according to the payment status.

[0003] The existing method of receiving electrical energy from the electronic module of an intelligent water meter to the motor transmission of the flow valve control is usually that the module circuit board is connected to the valve-controlled motor outside the module box by wires. Since the module box is connected to the valve-controlled reduction motor mechanism by wires, an additional opening needs to be opened on the module box to pass the wires. Even if the opening is sealed with sealant, it is difficult to ensure the long-term sealing of the module box. Due to the weathering and cracking of the sealant after long-term use, this opening sealant is even more easily penetrated than the sealant on the module box cover. This makes it difficult to ensure that the water meter is isolated from moisture penetration of the valve stem throughout its life. Utility Model Content

[0004] In view of this, and in view of the deficiencies of the prior art, the utility model provides a smart water meter valve driven by radio to solve the problem in the prior art that an additional opening is required on the module box for passing the wire, which makes it difficult to ensure the long-term sealing of the module box.
