Problems solved by technology

However, since the connecting rod is set in the pipeline, the movement of the connecting rod will be subject to the frictional resistance of its own mechanism, so it is not sensitive enough to the instantaneous water pressure change, and it is difficult to realize the function of stabilizing the pressure in an instant

Embodiment Construction

[0029] In the following, the present invention will be described and illustrated in more detail in the form of specific embodiments according to the accompanying drawings.

[0030] figure 1 It shows that the flow automatic regulating device according to the present invention is connected in the water inlet pipeline of the cold water pipe when used in a water heater. The water heater generally comprises a water tank 1, a hot water outlet pipe 2, a three-way mixing valve 3, an outlet pipe 4 of the three-way mixing valve 3, and a cold water inlet pipe 5 of the water heater. The flow automatic regulating device 6 of the present invention is connected between the cold water inlet pipe 7 (that is, the tap water pipe) and the cold water inlet pipe 5 of the water heater.

[0031] see below figure 2 The first embodiment shown is a detailed description of the automatic flow adjustment device of the present invention, and the automatic flow adjustment device includes:

Abstract

The invention provides an automatic flow rate adjusting device, which is characterized by comprising a shell (201), a cylindrical body (203) containing a tapered hole, a first magnet (205), and a second magnet (204), wherein a taper bottom side opening of the tapered hole of the cylindrical body (203) is communicated with a water inlet of the shell (201), and a taper top side opening is communicated with a water outlet of the shell (201); the second magnet (204) is movably arranged in the tapered hole of the cylindrical body (203); and the first magnet (205) is fixed in the shell (201). The automatic flow rate adjusting device automatically adjusts the drift diameter size of water flow at the water inlet by a magnetic induction mode, keeps the water flow at a constant pressure, achieves the function of stable pressure, and solves the problem of momentary sudden cold and sudden hot at the water outlet when the flow rate or the pressure at the water inlet of a water heater is decreased or increased suddenly.

Description

technical field [0001] The invention relates to a flow control device, in particular to a flow automatic regulating device. Background technique [0002] When a valve connected to a local water pipe network is opened, the water pressure in the pipe network changes. At this time, water users in the same pipe network will feel the change in water supply, and the water supply will return to normal. If the water heater is being used, the pressure of the hot water pipe and the cold water pipe of the water heater will be unstable due to sudden changes in the water pressure, resulting in hot and cold water coming out of the water heater. [0003] At present, in order to avoid hot and cold outlet water from the water heater, the method of stabilizing the water pressure input to the water heater inlet to solve the change of water temperature generally includes the following two methods: [0004] One method is to install a water storage tank device connected to the cold water pipe a...
