It can be understood that, by such an arrangement, it is not only beneficial to design the inner space of the valve body 10 so as to reduce the volume of the valve body 10, but also the water passing gap 13a is formed between the adjusting end 31 and the flow stabilizing ring 20, and can cooperate with the flow stabilizing ring 20 while adjusting the opening degree of the water passing gap 13a, so as to help ensure the water yield of the adjusting valve to be constant.

It can be understood that after the regulating valve core 30 is in threaded connection with the sheath 15 through the threaded section 33, and is in sealing connection with the sheath 15 through the sealing section 34, the sealing performance of the connection between the regulating valve core 30 and the valve body 10 can be improved, so that the sealing capacity of the regulating valve can be ensured. In the present embodiment, the sealing section 34 is located on the side of the threaded section 33 close to the flow stabilizing ring 20, so that water in the water supply channel 13 can be prevented from entering the joint of the threaded section 33 and the sheath 15, the risk of rusting of the threaded section 33 is reduced, and the service life of the regulating valve is prolonged. Of course, in other embodiments of the present application, the sealing section 34 may be located on the side of the threaded section 33 away from the flow stabilizing ring 20, or on both sides of the threaded section 33.

In the present embodiment, a sealing ring 35 is sleeved on the sealing section 34, and the sealing section 34 is in sealing connection with the sheath 15 through the sealing ring 35.

Further, in the present embodiment, the regulator valve core 30 is integrally molded. I.e. the adjustment end 31, the sealing section 34, the threaded section 33 and the driving end 32 are integrally formed. This arrangement facilitates production of the regulator insert 30 and facilitates assembly of the valve body 10.

The restrictor ring 22 is made of an elastic material, and the flow rate of the water in the water supply passage 13 is adjusted by the elastic force of the restrictor ring 22 itself. Specifically, when the water pressure of the inlet water is higher than the preset water pressure, the restrictor ring 22 is pressed to expand radially outward, so that the aperture of the restrictor 24 is increased, and thus the minimum water passing aperture of the water supply passage 13 is increased, thereby reducing the water pressure in the water supply passage 13. On the contrary, when the water pressure of the water inlet 11 is smaller than the preset water pressure, the throttle ring 22 contracts along the radial direction, so that the minimum water passing caliber of the water supply channel 13 is reduced, and the water pressure in the water supply channel 13 is increased, thereby keeping the water pressure in the water supply channel 13 basically unchanged before and after the water inlet pressure in the regulating valve is reduced, and keeping the water yield of the regulating valve stable.
