Scope: This document specifies the terms and definitions, models, technical requirements, testing and inspection, marking, packaging, protection, and storage of air intake control valves for screw compressors. This document is applicable to air intake control valves for screw compressors with a working pressure not exceeding 4.5 MPa and an air intake pressure not exceeding 0.2 MPa (absolute pressure), and the medium is non-corrosive gases such as air, nitrogen, and inert gases. Other rotary compressors can also refer to this document for implementation. Main technical content: This document proposes clear technical specifications and regulations for the model compilation method, technical requirements, inspection and acceptance, and packaging and storage of air intake control valves for screw compressors. It also provides reasonable restrictions on indicators such as high and low temperature performance, shock resistance, durability, and vacuum degree, providing guidance for product design and matching selection. The main technical indicators are complete and reasonable, and the testing methods are clear and feasible. The inspection rules are complete, which can guide enterprises in production and acceptance. The formulation of the standard is conducive to standardizing and unifying the production of air intake control valves for screw compressors in China, guiding the orderly, healthy, and rapid development of such products, improving product performance and reliability, and enhancing the technical level of air intake control for compressors in China.
