This Standard replaces GB/T 4119-1991 “Solenoid Valve For Refrigeration Equipment”. Compared with GB/T 4119-1991, main technical changes are as follows. - Revise the rang of application (see chapter 1, chapter 1 in edition 1991); - Revise terms and definitions (see chapter 3, chapter 3 in edition 1991); - Revise the basic parameters of solenoid valve; - Increase the requirements on dimension, material, appearance, level of protection, high temperature resistance, low temperature resistance, corrosion resistance, cleanliness, noise, breaking strength; - Revise the requirements on tightness, maximum opening pressure differential, internal leakage rate, insulation resistance, electrical strength, heat and humidity resistance, vibration resistance, durability and flow rate; - Revise the tightness, maximum opening pressure differential, internal leakage rate, insulation resistance, insulation resistance, electrical strength, heat and humidity resistance, durability and flow rate test method. This Standard was proposed by China Machinery Industry Federation. This Standard shall be under the jurisdiction of National Technical Committee on Refrigeration & Air-Conditioning Equipment of Standardization (SAC/TC238). Responsible drafting organizations of this Standard. Zhejiang Dunan Artificial Environment Co., Ltd., and Hefei General Machinery Research Institute. Participating drafting organizations of this Standard. Zhejiang Hongsen Machinery Co., Ltd., and Zhejiang Hengsen Industry Group Co., Ltd. Main drafters of this Standard. Li Weicao, Chen Huafeng, Zhang Mingsheng, Zhou Shuigen, and He Yongshui. Previous version replaced by this Standard is as follows. - JB/T 4119-1991. Solenoid Valve for Refrigeration Equipment1 ScopeThis Standard specifies terms and definitions, types, models and basic parameters, requirements, test methods, inspection rules, marking, packaging, transportation, and storage of solenoid valve for refrigeration equipment (hereinafter referred to as “solenoid valve”). This Standard applies to solenoid valve, of which the nominal diameter is not greater than 40 mm, and of which the pipes, high-and-low pressure steam pipes use R22, R134a, R404A, R407C and R410A as the refrigerants. Solenoid valves of using other refrigerants may reference to this Standard for use.2 Normative referencesThe articles contained in the following documents have become part of this document when they are quoted herein.
