Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water outlet control valve, in particular to a bubble water outlet valve. BACKGROUND

[0002] The bubble water machine produces bubble water by dissolving carbon dioxide in water. The bubble amount of the bubble water produced in the pressure tank of the bubble water machine is generally 2800-2900ppb. In order to ensure the taste of the bubble water, the bubble amount of the outlet water should not be less than 2600ppb. The existing bubble water machine generally uses a common outlet valve to discharge water. When the bubble water in the pressure tank is discharged through the outlet valve, the rapid pressure relief will cause the bubble amount of the discharged bubble water to be small (about 2300ppb), and the taste is poor.

[0003] In order to solve the above problems, there is also an outlet valve on the market, which can reduce the outgassing of bubbles in the bubble water to a certain extent and ensure the taste of the bubble water by setting a small hole in the outlet channel. However, in the above-mentioned way, the liquid pressure difference before and after the bubble water flows through the small hole is large, which causes the outlet flow rate to be too large, and the bubble water will splash when the water is received, which is poor user experience. SUMMARY

[0004] The purpose of the present application is to solve the problems in the prior art and provide a bubble water outlet valve that can ensure the taste of the bubble water and avoid splashing caused by excessive outlet flow rate.

[0025] Example 1

[0026] Referring to Figure 1 and Figure 2 , the present application is a bubble water outlet valve, the outlet valve comprising a water inlet channel 101, an outlet channel 102, a valve seat 103 arranged at the inlet end of the outlet channel 102, and a valve core 104 for blocking or opening the valve seat 103, the water inlet channel 101 of the outlet valve is provided with a flow limiting channel 1, and the cross-sectional area of the minimum radial cross-section of the flow limiting channel 1 is ≤ the cross-sectional area of the minimum radial cross-section of the outlet channel 102. In this embodiment, the inlet end of the outlet channel 102 has a small hole channel 10, and the cross-sectional area of the minimum radial cross-section of the flow limiting channel 1 is ≤ the cross-sectional area of the minimum radial cross-section of the small hole channel 10. The outlet valve of this embodiment has a bubble amount of about 2886ppb, which can meet the requirements of the taste of bubble water. In this embodiment, by adding a flow limiting channel 1 in the water inlet channel 101, the flow limiting channel 1 and the small hole channel 10 realize two small hole structures respectively to relieve pressure (of course, multiple small holes can also be used, but at least 2 or more small holes are guaranteed), that is, the large pressure difference is distributed through two small holes, and the small pressure difference is borne before and after the two small holes, so that the flow rate through the small hole can be reduced. According to Bernoulli's equation, the greater the flow rate, the smaller the pressure, and vice versa. The flow rate is reduced, and the pressure will not decrease too much, and the dissolved carbon dioxide content in the water will not be precipitated (carbon dioxide is combined with water by pressure). In this way, the bubble amount when water is discharged can be guaranteed, and at the same time, the problem of excessive water flow rate due to excessive pressure difference of the liquid flowing through the small hole channel 10 before and after the small hole channel 10 can be avoided, the problem of bubble water splashing when the water is discharged can be reduced, and the user experience is improved.

[0027] Further, referring to Figure 2 , the outlet valve further comprises a flow control assembly 2 mounted in the water inlet channel 101, and the flow control assembly 2 has a flow limiting channel 1. Specifically, in this embodiment, the flow limiting channel 1 is arranged along the axial direction of the flow control assembly 2, and comprises a first through cavity 201 and a second through cavity 202 arranged in sequence in the water outlet direction, and the radial cross-sectional area of the first through cavity 201 is smaller than that of the second through cavity 202. The inlet end of the first through cavity 201 is further provided with a radial reduction cavity 203 which gradually reduces in radial cross-section in the water outlet direction.

[0028] Further, a sealing ring is arranged between the flow control assembly 2 and the water inlet channel 101 to improve the reliability of the sealing therebetween, and the outer portion of the flow control assembly 2 has a sealing ring groove 200 for mounting the sealing ring.

[0029] Embodiment 2

[0030] The difference between this embodiment and Embodiment 1 is that the structure of the flow-limiting channel 1 and the flow control assembly 2 is different. Referring to Figure 1 and Figure 5 , specifically, in this embodiment, the flow-limiting channel 1 is an annular gap provided at the outlet end of the water inlet channel 101, the radial cross-sectional area of the annular gap gradually increases in the water outlet direction, and is used to control the flow. The water outlet valve using this embodiment has a water bubble amount of about 2890ppb, which can meet the requirements of the taste of bubble water. In this embodiment, the original small hole is changed to an annular gap, which greatly increases the contact area of water and pipe wall. The annular gap can make the bubble water flow close to the pipe wall of the channel, thereby reducing the flow rate. According to Bernoulli's equation, the greater the flow rate, the smaller the pressure, and vice versa. The flow rate is reduced, and the pressure does not decrease too much, so the dissolved carbon dioxide content in the water will not be precipitated (carbon dioxide is dissolved with water by pressure). This can not only ensure the bubble amount when water is outlet, but also reduce the flow rate to avoid the problem of splashing of bubble water when water is outlet, thereby improving the user experience.

[0031] Further, referring to Figures 6 to 8 , the water outlet valve further comprises a flow control assembly 2 installed at the outlet end of the water inlet channel 101, and the end of the flow control assembly 2 has a cone 221, which extends into the outlet end of the water inlet channel 101 and forms an annular gap therebetween (the conical surface is used to control the size of the flow). Specifically, in this embodiment, the flow control assembly 2 comprises an outer sleeve body 21 and an inner core body 22 arranged in sequence from outside to inside, and a plurality of connecting ribs 23 connected between the two. The outer sleeve body 21 and the inner core body 22 have a cavity connected with the water inlet channel 101, and the end of the inner core body 22 has a cone 221, and the outer wall of the cone 221 and the outlet end of the water inlet channel 101 form an annular gap therebetween.

[0032] The above embodiments are illustrative of the present application, but not limiting of the present application. Any simple transformation of the present application is within the scope of protection of the present application.
