The situation of Dongguan purification engineering equipment and the assumption of the process layout. After that, the designer should work with the owner to determine the division of each functional area of the clean plant, determine the air cleanliness level and various control parameters of various production processes (rooms) --- Temperature, relative humidity, differential pressure, micro-vibration, purity of high-purity substances and impurity content, preliminary selection of air flow patterns in clean rooms, preliminary estimation of purification air-conditioning systems, comparison and determination of design schemes, and layout of clean plant , Space layout.
At this time, the Dongguan purification project must first arrange a reasonable layout of the product production area, the production auxiliary area, and the power utility area. It is usually in accordance with the production process flow of the product and is conducive to ensuring the production environment of the product. The operation and management of product production are conducive to saving energy and reducing production costs. The planar layout of the clean room must comply with the relevant national safety regulations in terms of safe production.
1 Valve body / trim specifications This content mainly includes: valve type, valve type, nominal diameter, valve seat size, valve core form, flow characteristics, leakage level, valve body material, valve core material, valve seat material, CV value, flange standard grade size and sealing surface form, etc., if any content is found to be inconsistent with the design, the design shall be determined and approved.
2 Actuator part This item should mainly check the model, type, action form, spring range, air supply pressure, etc. of the actuator.
3 Positioner section This content mainly checks the input signal of the positioner, the pressure of the gas source, the size of the electrical and gas interface, and the explosion-proof level. The explosion-proof level must not be lower than the design level.
