Problems solved by technology

There is an unreasonable point in this structural design, that is, the water inlet area of ​​the water inlet of the large water hole and / or the small water hole is greater than or equal to the water outlet area of ​​the water outlet. The water flow noise, especially the small water hole generally has a relatively small aperture, and the water flow noise generated under the same water flow will be greater than that of the large water hole
When applied to a water heater with a large number of liters, due to the large water flow, the noise of the water flow will be very loud, which greatly affects the experience of using the gas water heater

Abstract

The invention discloses a valve core, which comprises a valve core body, an opening is arranged on the upper end of the valve core body, an annular groove is arranged on the outside of the valve core body, a connecting portion is arranged on the periphery of the opening, and the connection between the opening and the valve core body It is a transition section, a first water outlet is opened at the transition section, and a second water outlet is arranged below the first water outlet. The beneficial effect of the present invention is: the structure is simple, the periphery of the opening is provided with a connecting portion, which is convenient for installation, and the diameter of the second water outlet is larger than that of the first water outlet, thereby effectively reducing the water flow at the water outlet of the valve core due to pressure noise.

Description

technical field [0001] The invention relates to a valve core. Background technique [0002] With the improvement of people's living standards, gas water heaters have already entered the homes of ordinary people, and the water inlets of gas water heaters are generally equipped with rotary water valves that can adjust the water flow to meet the needs of different water flows of gas water heaters. In addition, this rotary water valve also plays an important role in other water flow control. [0003] The spool of a traditional rotatable water valve includes a cylindrical spool body, a small water hole and a large water hole arranged on the spool body and intersecting with each other at the axis of the spool body. Wherein, the water inlet area of ​​the water inlet of the large water hole is greater than or equal to the water outlet area of ​​the water outlet of the large water hole, and the water inlet area of ​​the water inlet of the small water hole is greater than or equal to...
