Abstract
The invention discloses a wax heat power element of a three-way thermostatic valve. A thermosensitive material of a temperature induction part in a traditional thermostatic adjusting valve (also called as a temperature control valve) generally adopts an intelligent material, such as a shape memory alloy. The driving characteristic of the intelligent material has limitation; and the intelligent material is generally difficult to synchronously satisfy the requirements of micro displacement and high driving force needed by the thermostatic valve. The wax heat power element of the three-way thermostatic valve consists of a piston, a capsule rubber body, a sealing container and temperature inducing wax, and is characterized in that the temperature inducing wax is sealed between a copper cover and a rubber cover; a fluid or steam passes through a heat power element; and when the wax heat power element is heated, heat passes through the outer wall of the rigid red copper sealing container to fuse paraffin in a cup for volume expansion, and the capsule rubber body is pushed to push the piston to drive movement of the adjusting sleeve. The wax heat power element is applied to the thermostatic valve.
