Conditional graphical notation and diagrams. Part 1. Contingent graphics notation in parts of air conditioners working environment and hydraulic and pneumatic capacity of 4 Decree of the State Committee of Russian Federation for Standardization, Metrology and Certification of the April 7, 1997 № 121 interstate standard GOST 2.780-96 put into effect immediately as a state standard of the Russian Federation with a January 1998 5 INSTEAD GOST 2.780-68 in part pp. 1, 2, 18-25 June republication. October 2000 1 Scope This Standard specifies graphical symbols conditioned air conditioners working fluid and working gas, hydraulic and pneumatic reservoirs in diagrams and drawings of all industries. 2 Normative references in this standard references to the following standards: GOST 17752-81 Hydraulic drive volume and actuator. Terms and definitions GOST 20765-87 Lubricating systems. Terms and definitions GOST 26070-83 filters and separators for liquids. Terms and Definitions 3 Definitions In this standard use the terms in accordance with GOST 17752, GOST 20765, GOST 26070. 4 CORE PROVISIONS 4.1 Legend reflect the purpose of (action), the method of operation of the devices and external connections. 4.2 Designation does not show the actual construction of the device. 4.3 Sizes of symbols are not standard installs. 4.4 Conditional graphical notation conditioners working environment, hydraulic and pneumatic tanks are listed in Table 1. Table 1 Name of Designation of a condenser the working environment: - a generic term - the filter with a magnetic separator with an indicator of pollution - water separator with a manual condensate drain with automatic condensate drain - filter-drier with a manual condensate drain - dehumidifier - lubricator - block preparation of the working gas - humidifier - heater - cooler without the lines for supplying and draining the coolant - cooler with lines indicating the inlet and outlet coolant - Cooler and Heater - Tank Trap 2 and lubricant tank: at atmospheric pressure: - a generic term - with a drain pipe above the fluid level - with drain pipe below the fluid level - with a drain pipe below the fluid level, air filter - with a paddle - mechanically compressing the lubricant with pressure above atmospheric pressure: - a generic term - with a drain pipe above the fluid level - with a drain pipe below the fluid level with pressure below atmospheric: - a generic term - with a drain pipe above the fluid level - with a drain pipe below the fluid level Note - If you need to specify the volume of filling the tank, dm3 (l) should be applied given the designation (eg, a tank with a volume filling 5 dm3). 3 battery hydraulic or pneumatic (depicted vertically only) - Hydraulic (without specifying the action principle) - hydraulic truck - spring-loaded hydraulic - 4 Auxiliary Air hydraulic gas cylinder (depicted vertically only) 5 Receiver 6 7 Silencers fill opening, funnel, charging connection, and so n. 8 pressureless capacitive oiler (for example, adjustable oiler trehotvodnaya) 9 Capacitive Pressure oiler: - Pneumatic - Cap Key words: Graphical symbols, air conditioners, tanks, hydraulic and pneumatic components 1 Scope 2 Normative references 3 Definitions 4 Fundamentals Published 7/7/2008 Standards on the topic "Electrical, lighting, security systems," GOST 15597-82 Fixtures for industrial buildings.
