Referring to fig. 1-3, an automatic temperature control water flow device includes a housing 1, a valve core 2 is slidably installed in the housing 1, a memory spring 4 which is elastically deformed when the temperature of a fluid changes to drive the valve core 2 to move and change the flow of the fluid in a unit time is installed at one end of the valve core 2, and the memory spring 4 is a memory alloy spring and has the characteristics of deforming at a low temperature and recovering to a shape before deformation after heating.
Specifically, two water passing holes 101 which are symmetrical and coaxial are formed in the shell 1, a channel 102 communicated with the water passing holes 101 is formed between the two water passing holes 101, the valve element 2 is slidably mounted in the channel 102, the outer diameter of the valve element 2 is equal to the diameter of the channel 102, the central line of the valve element 2 is perpendicular to the central line of the water passing holes 101, an annular groove 201 which is sunken towards the central direction is formed in the middle of the outer diameter of the valve element 2, the width of the annular groove 201 is matched with the diameter of the water passing holes 101, and the valve element is mainly used for controlling the flow of a valve body when the valve element 2 moves along the axis of the valve element.
Specifically, a common spring 3 is installed at one end of the valve core 2, one end of the common spring 3 is in contact with the inner wall of the shell 1, the other end of the common spring 3 is in contact with the root of the groove at the end of the valve core 2, under the normal temperature condition, the elastic force of the common spring 3 is smaller than that of the memory spring 4, the compression amplitude of the common spring 3 is large, and the valve core 2 is located at the left side position shown in fig. 3, so that the normal flow supply of the water heater is met.
Specifically, an installation seat 5 is installed in the channel 102, the memory spring 4 is installed between the installation seat 5 and the valve core 2, the installation seat 5 is connected in the casing 1 in a threaded connection mode, a sealing ring 6 is installed at the joint of the installation seat 5 and the casing 1, the installation seat 5 is mainly used for positioning the memory spring 4 and achieving the assembling requirement, in addition, the installation seat 5 and the casing 1 are in threaded connection, so that the position of the installation seat can be adjusted according to actual needs, compression of the memory spring 4 in different degrees is achieved, the sealing ring 6 is arranged to achieve a good sealing effect, and fluid leakage is avoided.
