Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] Such as figure 1 As shown, a detachable impeller-type flow sensor includes a housing 1 and an impeller-type sensor assembly 2. The housing 1 includes an impeller chamber 1A, a water inlet port 1B communicating with the impeller chamber, and a water inlet port 1B communicating with the impeller chamber. The water outlet interface 1C and the assembly seat 1D communicating with the impeller cavity, the impeller sensor assembly 2 includes the impeller 21, the impeller shaft 22, the circuit board 23, the Hall sensor (not marked in the figure), the magnetic assembly 24 and the base 25 ; The base 25 is detachably connected to the component seat 1D.

[0028] There is an inner ring platform 3 and an upper ring platform 4 inside the component seat 1D, and there is an annular clamping groove 5 on the wall of the component seat 1D at the upper surface of the upper ring pla...

Abstract

An easily disassembled impeller-type flow sensor, comprising a housing and an impeller-type sensor assembly, the housing includes an impeller chamber, a water inlet port communicated with the impeller chamber, a water outlet port communicated with the impeller chamber, and a water outlet port communicated with the impeller chamber The assembly seat of the base also includes an open retaining ring, the part of the lower part of the steps of the base is liquid-tight with the assembly seat at the lower part of the inner ring platform, and the steps are supported and matched with the inner ring platform; the radially outer side of the open retaining ring is embedded in the ring The inside and the radial inner side of the card slot cooperate with the radial edge of the top of the base. Due to the adoption of such a structure, when the impeller sensor assembly is disassembled, especially in the environment where the pipeline is densely covered and a wrench cannot be used, it is only necessary to disassemble the opening retaining ring with bare hands or needle-nose pliers; and then it can be removed by hand without any tools. The impeller sensor assembly is taken out and disassembled easily. When assembling, just insert the impeller assembly into the impeller chamber with bare hands, and then assemble the opening retaining ring, which is convenient for assembly.

Description

technical field [0001] The invention relates to a water flow sensing device. Background technique [0002] In the current prior art, an impeller-type flow sensor includes a housing and an impeller-type sensor assembly. Connected assembly seat, the impeller type sensor assembly includes impeller, impeller shaft, circuit board, Hall sensor, magnetic assembly and base, the impeller is pivoted on the impeller shaft, and the magnetic assembly is fixed on the impeller; the upper end of the impeller shaft and The base is pivotally connected, and the lower end is pivotally connected with the impeller cavity, and the base is screwed with the assembly seat. The existing problem is that it is inconvenient to disassemble the impeller type magnetic assembly. Contents of the invention [0003] The purpose of the present invention is to provide an easily disassembled impeller type flow sensor, which has the characteristics of convenient disassembly of the impeller magnetic assembly. ...
