Chemical slicing machine is a device that converts heated liquid raw materials into adjustable slicing knives by rotating the adhesive liquid material in the material groove through an internally cooled rotating cylinder, thereby completing the conversion of liquid to solid sheet materials. It can also slice raw materials that have been cooled into crystals. Widely used in industries such as chemical and pharmaceutical industries. The raw materials formed by slicing machines are superior to other crushing processing materials in terms of product grade. Moreover, the equipment has good stability, convenient operation, and the thickness and output of the slicing material can be determined based on the characteristics of the raw materials. The rotation speed is determined by the feeding speed. Slice specifications can be customized according to customer's quantitative requirements.

Temperature control valve selection design
Temperature control valve is the most important heating system flow control equipment, and other control valves are auxiliary equipment, so the temperature control valve is essential. A heating system without the thermostatic valve can not be called the so-called heat metering and charging system. In the design of temperature control valve, the correct selection is very important. The purpose of temperature control valve selection, according to the design flow (known heat load), allowing the resistance to determine KV value (flow coefficient); then KV value to determine the temperature control valve diameter (model). Therefore, the design catalog or manufacturer's samples must give the relationship between KV value and diameter, otherwise it is not convenient for designers to use. Selection of temperature control valve design, by no means simply select the same diameter with the pipeline temperature control valve that is down. But in the selection process, the selected temperature control valve to create an ideal working conditions of pressure. A temperature control valve is usually the working pressure between 2 ~ 3mH2O, the maximum does not exceed 6 ~ 10mH2O.To this end, we must give the temperature control valve preset range, to prevent noise, affecting the temperature control valve normal work. When the same KV value, there are more than two choices of caliber, should be given priority to choose a small caliber thermostatic valve, the purpose is to improve the thermostatic valve regulating performance.
