The invention relates to a memory type constant flow pipe based on controlled liquid flow and an achievement method. The memory type constant flow pipe comprises a memory type constant flow pipe body based on controlled liquid flow, wherein the memory type constant flow pipe body is formed by a liquid inlet end pipe body and a liquid outlet end pipe body in a threaded connection manner; the memory type constant flow pipe is characterized in that a spheroidal cavity is arranged in the body, a spheroidal elastic liquid runner ring is arranged in the spheroidal cavity, a deformable metal ball is arranged in the spheroidal elastic liquid runner ring, and a thermo-sensitive device is arranged in the deformable metal ball; the thermo-sensitive device is controlled by temperature and pressure conditions set by a thermo-sensitive temperature and pressure controller to generate temperature changes, so that deformable metal ball generates swelling or shrinking of the ball volume along with temperature changes of the thermo-sensitive device, and meanwhile, the runner volume of the spheroidal elastic liquid runner ring is compressed or back enlarged in equal proportion; constant control over the liquid flow is achieved; and the deformable metal ball is made of a shape memory alloy.
Description
technical field [0001] The invention belongs to the technical field of liquid flow control, and in particular relates to a memory type constant flow tube based on controllable liquid flow and a realization method. Background technique [0002] The existing known constant flow valves that can control the flow of liquid use the principle that the cross section of the liquid flow channel changes inversely with the change of the pressure of the liquid to achieve constant control of the flow of the liquid. However, most of the structure of the constant flow valve uses a spring device to change the cross section of the liquid flow channel. Because the spring device is soaked in the liquid for a long time, it will be corroded, and its self-deformation performance after being under pressure often does not reach the predetermined design effect. , directly affects the control accuracy of the constant flow valve. [0003] Chinese patent application 200910153019.9 discloses a "constant...
