Embodiment 1

[0039] Embodiment 1, a dual-control thermostatic valve core:

[0040] Such as Figures 1 to 3 As shown, a dual-control thermostatic spool includes an outer valve body 1 (such as Figure 5 and Figure 6 As shown), the outer valve body 1 is stepped, and the steps are divided into three stages, and the diameter of the outer valve body 1 gradually increases from top to bottom. The outer valve body 1 is hollow inside and is used for installing a water temperature regulating mechanism. The water temperature adjustment mechanism includes an adjustment knob 2, a sliding block 5, a push rod 6, a water temperature adjustment valve core 8, a temperature sensing component and an inner valve body 9 installed in the outer valve body 1 sequentially from top to bottom. The upper end of the adjustment knob 2 protrudes from the outer valve body 1 , and the lower end is inside the upper end of the outer valve body 1 . A threaded hole is arranged at the center of the lower end of the adjustme...

Embodiment 2

[0046] Embodiment 2, a dual-control thermostatic valve core

[0047] Such as Figure 11 As shown, the difference between Embodiment 2 and Embodiment 1 is that the temperature-sensing component of Embodiment 2 is a temperature-sensing spring 19 made of memory alloy, and the temperature-sensing spring 19 is located in the mixing chamber 95, and its upper end is connected with the water temperature regulating valve core. 8. The lower surface is in conflict, and the lower end of the temperature-sensitive spring 19 is at the installation position of the back-moving spring 14 on the base 4. During use, feed cold water into the hot water supply port 44 and feed hot water into the cold water supply port 46 . At the same time, the elastic coefficient of the spring 13 is smaller than that of the temperature-sensing spring 19 . When the spool only passes cold water, the water temperature regulating spool 8 is pressed on the lower side of the inner spool, so that the outlet 91 of the ho...

Abstract

The invention discloses a double-control thermostatic valve core comprising an outer valve body, a valve seat and a base. The outer valve body is internally provided with a water temperature regulating mechanism, and the lower end of the valve seat is provided with a water volume regulating mechanism; the valve seat is sheathed into the outer valve body from the upper end of the outer valve body, and arranged at the outer side of the lower part of the outer valve body, and the lower end of the valve seat is fixedly connected to the base; the outer valve body is of a multistage integrated structure; the interior of the outer valve body is hollow, and the lower end of the outer valve body is provided with an opening; and the water temperature regulating mechanism and the water volume regulating mechanism are sheathed into the outer valve body and the valve seat from the lower end of the outer valve body. The double-control thermostatic valve core has the advantages of simple overall structure and easy assembly, and the production efficiency can be improved effectively.

Description

technical field [0001] The invention relates to a thermostatic valve, in particular to a dual-control thermostatic valve core. Background technique [0002] The thermostatic spool is a commonly used device in high-end sanitary products. The original thermostatic valve core can only realize the control of the water temperature, but cannot realize the control of the outlet water flow. If it is necessary to realize the control of the outlet water flow of the thermostatic valve, it is necessary to add another on-off valve to control the outlet water flow. If such a thermostatic valve is installed in a thermostatic faucet, it is necessary to install another on-off valve to control the water flow. This time, the overall structure of the thermostatic faucet is larger, and the waterway structure is more complicated, which will also affect the overall appearance of the thermostatic faucet. [0003] At present, the Chinese patent with the publication number CN 205315776 U discloses...
