Problems solved by technology

It has the following disadvantages: 1. Since the water-saving sheet is supported by the annular sheet, and the annular sheet is basically a plane, the deformation of the water-saving sheet is small, and the water volume adjustment range is small. The sensitivity is not high, and the adjustment accuracy is low; 2. Since the deformation direction of the water-saving sheet is perpendicular to the water pressure direction, the deformation amount is small, the water volume adjustment range is small, the deformation sensitivity to water pressure changes is not high, and the adjustment accuracy is low. lower

Embodiment Construction

[0041] Please check Figure 1 to Figure 9 , a flow regulating device, which includes a housing 100, a regulating part 200 and a limiting part 300.

[0042] The casing 100 is provided with a water passage in it, and the water passage is a stepped hole, and the stepped hole has an assembly hole 110 , a flow hole 120 and a stepped surface 130 . A plurality of protruding seats 140 arranged in a circular arrangement are fixed on the stepped surface 130, and there is an interval between the two adjacent protruding seats 140. In this embodiment, the protruding seats 140 are formed into ribs, and , the inner ends of the ribs are stretched out and fixed together, and the outer ends of the ribs are fixed on the inner surface of the assembly hole. In this embodiment, it is taken as an example that the inner ends of the ribs protrude and are fixed together, but it is not limited to this. This embodiment is applicable. A positioning platform 141 protrudes from the outer end of the rib, ...

Abstract

The invention discloses a flow regulating device comprising a case and a regulating piece, wherein a water channel is arranged in the case and is a stepped hole, the stepped hole is provided with a step plane which is fixedly provided with a plurality of bulged bases thereon, and an interval is formed between two adjacent bulged bases. The regulating piece is made of an elastic material and can carry out elastic deformation under stress; the regulating piece is installed in the case and is arranged on the bulged base; spaces above the step plane, below the regulating piece and between two adjacent bulged bases form the water passing port of the water channel; and the elastic deformation of the regulating piece is regulated to press parts of the regulating piece into the water passing port so as to change the water passing section area of the water passing port. The invention has the advantages that the regulating piece is arranged above the bulged base, and the bottom surface of the regulating piece, which corresponds to the water passing port, has no support; the direction of the elastic deformation of the regulating piece is the same with flow direction, so that the regulating piece has big elastic deformation, wide water amount regulating range, high sensitivity for the elastic deformation aiming at pressure change and high regulating veracity.

Description

technical field [0001] The invention relates to a flow regulating device. Background technique [0002] Early flow regulating devices mainly include a housing, a seal and a spring. Between the bodies, the flow of the water passage is controlled by the sliding of the sealing member relative to the water passage. When the water pressure is greater than the predetermined pressure, the sealing member slides in the positive direction under the action of the water pressure to reduce the cross-sectional area of ​​the water passage and reduce the flow of the water passage, and during the sliding process, the spring is compressed to store energy; When the water pressure is lower than the predetermined pressure, the energy storage spring releases energy and drives the sealing member to slide in the opposite direction to increase the cross-sectional area of ​​the water passage and increase the flow rate of the water passage. Since the adjusting device includes a seal and a spring, th...
