Abstract

This invention relates to a wax mediator which is applied to the automatic enrichment valve of the motorbike and its preparation method. It takes use of the liquid wax which contains the component of C9-C30 and soap wax as the material, and it can be prepared by the processes of vacuum distillation, mixing, refining and so on. The wax controlled valve which is prepared by this product can control the temperature during 0-50 deg.C, and the driving value of each degree is basic same. This invention can be applied to the automatic controlled part which can control the temperature during 0-50 deg.C and the driving value of which can change homogeneously as the temperature. It is especially suitable to as the temperature sensitive mediator of the automatic enrichment valve in motorbike.

Description

technical field [0001] The invention belongs to the technical field of special waxes, in particular to a waxy temperature-sensing medium for a waxy control valve and a preparation method thereof, in particular to a waxy temperature-sensing medium for a motorcycle automatic thickening valve and a preparation method thereof. Background technique [0002] The control valve using wax as the temperature-sensing medium is a self-operated valve, which uses the volume change of the wax-like temperature-sensing medium during the phase change process to control the opening of the valve so as to achieve the purpose of controlling the flow of the material flow. This kind of valve has multiple functions such as sensing, execution, feedback, and fixed value at the same time. It has temperature characteristics that do not change significantly with system pressure, high mechanical strength, good chemical stability, easy mass production and installation, low cost, and stable and reliable temp...
