Foreword

This standard replaces GB/T 13852-1992 "marine hydraulic control valve technology conditions." This standard compared with GB/T 13852-1992, mainly in the following changes.

--- Increasing the terms and definitions section;

--- Increase marine hydraulic control valve interface requirements. The Standard Annexes A and B are normative appendix. The standard proposed by China Shipbuilding Industry Corporation. This standard by the National Marine Machinery Standardization Technical Committee. This standard was drafted. China Shipbuilding Industry Corporation seventh - four Institute. The main drafters of this standard. Le Yi, Zhang Xiaodong, Jin Bei, the rich root, Chen FIG. This standard replaces the standards previously issued as follows:

--- GB/T 13852-1992. Marine hydraulic control valve technical conditions

1 Scope

GB/T 13852-2009 is the Chinese national standard on general specification of hydraulic control valves for ship, in the field of shipbuilding and marine structures. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 9 March 2009 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 November 2009. Classification: ICS 47.020.30, CCS U57. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the privateers with the hydraulic control valve (hereinafter referred to as marine hydraulic valve) classification, requirements, test methods and inspection rules. This standard applies to petroleum-based hydraulic oil as the working medium of the marine hydraulic valve (except proportional hydraulic valves, servo valves, cartridge valves and valve superposition Outside) design acceptance.
