Problems solved by technology

[0007] 4. In the temperature-sensitive movable valve core, cold water flows through a general cold water port, and hot water flows through a general hot water port. The water flow is not easy to control, and a slight movement of the slider may cause a sharp change in the water flow. , the temperature is difficult to adjust and set precisely

Embodiment 1

[0035] See figure 1 , figure 2 , a temperature control valve core, including a valve core sleeve composed of a middle sleeve 1, a water outlet sleeve 2 threaded to one end of the middle sleeve 1, and a pressure sleeve 3 threaded to the other end of the middle sleeve 1. The first water inlet 4 (i.e. the hot water channel) and the second water inlet 5 (i.e. the cold water channel) are set on the cover 1, the water outlet 6 (i.e. the mixed water channel) is arranged on the water outlet cover 2, and the middle cover 1 is equipped with The spool inner core 7, the main body of the spool inner core 7 is a hollow cylinder, the spool inner core 7 is limited by the inner core spring 18 and the abutment head 19, the abutment head 19 cooperates with the adjustment screw 20 through threads, and the adjustment screw 20 passes through The pressure sleeve 3 is also clamped by the collar 21, and one end of the inner core spring 18 is pressed against the water outlet sleeve 2, and the other e...

Embodiment 2

[0040] See Figure 7 , the difference between this embodiment and the first embodiment lies in the structure of the notch 15, the notch 15 is another deformation of the protrusion 14, which is used to cooperate with the outer circumference of the inner core spring 18, and its function is the same as image 3 The effect of the protrusion 14 in is exactly the same.

Embodiment 3

[0042] See Figure 8 The difference between this embodiment and the first embodiment is that there are only two first through-slots 8 and two second through-slots 9, the lengths of the two first through-slots 8 are different, and the lengths of the two second through-slots 9 are different.

Abstract

The temperature controlled valve core includes one middle casing with the first water inlet channel and the second water inlet channel; one water outlet casing with water outlet channel connected to one end of the middle casing and one pressing casing connected to the other end of the middle casing. Inside the middle casing, there are a valve core as an axially limited hollow cylinder, two first grooves and two second grooves on the outer surface of the valve core and in the positions near the first water inlet channel and the second water inlet channel separately; the first axially positioned elastic ring and the second elastic ring separately in the first grooves and two second grooves, and one sealing ring set between the first grooves and the second grooves. The first water inlet channel is communicated with the water outlet channel through the first grooves, and the second water inlet channel through the second grooves. The present invention has precise temperature setting, stable temperature stabilizing effect and high reliability.

Description

technical field [0001] The invention relates to a constant temperature control device, in particular to a temperature control valve core for sanitary equipment. Background technique [0002] The current thermostatic valve is more common in bathroom equipment, and its purpose is to mix cold water and hot water to provide warm water suitable for use. There have been temperature-controlled spool products, such as the Chinese patent CN200420045079.1, which discloses a temperature-sensitive movable spool, and the inner core of the spool used in the temperature-sensitive movable spool is a sliding block that can slide axially , adjust the size of the cold water port and the hot water port by sliding the slider in the valve core, so as to realize the adjustment of the temperature of the mixed water. Due to the influence of water pressure, the amount of cold water inlet and hot water inlet will change and affect the temperature of the mixed water. The temperature-sensitive movable ...
