Referring to fig. 1 to 6, a preferred embodiment of a flow-limiting structure of a wall-in type valve body includes a valve body 10, a flow-limiting assembly 20, and a valve core 30.

The valve body 10 is provided with a valve cavity 11, and the valve cavity 11 is provided with a water outlet hole 12.

As shown in fig. 4, the valve body 10 further has two assembly cavities 13, and the two assembly cavities 13 may be respectively provided with a pause valve core and a temperature regulating valve core, or may be provided with a cold water flow valve core and a hot water flow valve core, which are not limited to this.

In this embodiment, the water outlet 12 is formed by sequentially connecting a plurality of circular arcs, and the shape of the water outlet 12 is not limited thereto, and may be square or circular.

The valve core 30 is installed in the valve cavity 11 and is provided with a valve core water outlet communicated with the water outlet hole 12, and the flow limiting assembly 20 is limited in the water outlet hole 12. The valve core 30 can be a switch valve core or a temperature regulating valve core. As shown in fig. 1, the valve core 30 is fixed relative to the valve body 10 by the screw engagement between the valve cover 40 and the valve body 10.

In this embodiment, the flow restricting assembly 20 includes a flow restricting bracket 21 and a flow restrictor 22. The flow limiting bracket 21 is limited in the water outlet hole 12 and is provided with a hollow accommodating cavity 23, and the flow limiter 22 is arranged in the accommodating cavity 23. The specific structure of the flow restrictor 22 is conventional and will not be described in detail.

As shown in fig. 5 and fig. 6, two elastic arms 24 are disposed at the top end of the current limiting bracket 21 at intervals, and the two elastic arms 24 are respectively located at the left and right sides of the accommodating cavity 23; when the flow-limiting bracket is placed in the water outlet hole, the bottom end of the valve core is pressed against the elastic arm 24. Moreover, the bottom end of the accommodating cavity 23 is provided with an opening 231, so that the cost can be saved.

As shown in fig. 3, the current-limiting bracket 21 is provided with a limiting boss 25, and the limiting boss 25 abuts against the top end surface of the water outlet hole 12.

In order to make the assembly between the flow limiting bracket 21 and the water outlet hole 12 more compact, the bottom end surface of the flow limiting bracket 21 is matched with the wall of the water outlet hole 12.

In this embodiment, a supporting platform 26 transversely disposed along the cavity wall of the accommodating cavity 23 is disposed inward at the bottom end of the accommodating cavity 23, and the bottom end surface of the flow restrictor 22 abuts against the supporting platform 26.

In order to prevent the flow restrictor 22 from easily moving up and down in the accommodating cavity 23, the wall of the accommodating cavity 23 is further provided with a rib 27 extending longitudinally along the wall of the accommodating cavity 23, and the periphery of the flow restrictor 22 is tightly matched with the rib 27.

When the flow limiting assembly 20 needs to be used, the flow limiter 22 is only placed in the accommodating cavity 23, and the periphery of the flow limiter 22 is tightly matched with the rib 27; then the flow-limiting component 20 is placed in the water outlet hole 12 of the valve body 10, and the limiting boss 25 abuts against the top end face of the water outlet hole 12; the valve element 30 is then inserted into the valve chamber 11, with the bottom end face of the valve element 30 pressing against the resilient arm 24. The installation of the in-wall valve structure is completed.

When the flow-limiting assembly 20 is not needed, the valve core 30 is detached from the valve cavity 11, the elastic arm 24 is held by hand to take out the whole flow-limiting assembly 20 from the water outlet hole 12, and then the valve core 30 is installed in the valve cavity 11. Because the flow limiting assembly 20 is only in limit fit with the valve body 10 and the valve core 30, when the flow limiting assembly 20 is taken out, the wall-in type valve structure is used as usual and is not influenced.

The above description is only a preferred embodiment of the present invention, and therefore the scope of the present invention should not be limited by this description, and all equivalent changes and modifications made within the scope and the specification of the present invention should be covered by the present invention.
