Detailed Description

The technical scheme and beneficial effects of the present utility model will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1 and 2, a water flow regulating insert comprises a housing 1, a through-flow seat 2 and a movable plug 3.

Wherein the housing 1 has a water inlet end 11 and a water outlet end 12. The water inlet end 11 is provided with a limiting throat part 101, and the limiting throat part 101 is in a horn shape with a small upper part and a large lower part. An annular groove 102 is arranged on the outer side of the water inlet end 11 of the shell 1, and a first O-shaped sealing ring 103 is arranged in the annular groove 102. The water outlet end 12 is clamped with the through-flow seat body 2.

The center of the through-flow seat body 2 is provided with a hole column 21. The through-flow seat 2 extends toward the inner water inlet end of the housing 1 to form a peripheral wall 22, and ribs 23 are uniformly distributed inside the peripheral wall 22. The inner side of the shell 1 is provided with annular ribs 104, and correspondingly, the outer side of the through-flow seat 2 is provided with annular grooves 24. The shell 1 is matched with the annular groove 24 through the convex edge 104 so as to realize clamping connection with the through-flow seat body 2.

The elastic movable plug 3 is slidably disposed in the space defined by the through-flow seat 2 and the limit throat 101. The elastic movable plug 3 includes a spring 31 and a movable plug 32, and the movable plug 32 includes a plug portion 321 and a rod portion 322.
