采暖散热器是量大面广的产品,为了便于生产,保证质量和设计使用,标准化工作很重要。苏联散热器分为三大类:铸铁散热器、钢制板式散热器和钢制带罩对流器。对每种散热器分别制定了国家标准。现将三大类散热器主要参数和尺寸、材质、试验综述如下: 铸铁散热器标准(8690-75)适用于热媒温度低于130°,工作压力低于6公斤/厘米~2的采暖系统。铸铁散热器的主要参数和尺寸应符合表1所示数值。钢制板式散热器标准(20335-74)适用于热媒温度低于150℃的热水采暖系统,而且要求系统的含氧量<0.05克/米~3。板式散热器有接头中心距为500毫米和300毫米的两种。接头中心距为500毫克的,工作压力可为6～9公斤/厘米~2;接头中
Heating radiators are a wide range of products. In order to facilitate production and ensure quality and design use, standardization is very important. Soviet radiators fall into three main categories: cast iron radiators, steel plate radiators, and steel convection hoods. National standards have been established for each type of radiator. The main parameters and dimensions, materials and tests of the three categories of radiators are summarized as follows: The standard for cast iron radiators (8690-75) is applicable to heating systems with a heating medium temperature of less than 130° and a working pressure of less than 6 kg/cm2. . The main parameters and dimensions of cast iron radiators should meet the values shown in Table 1. Steel plate radiator standards (20335-74) apply to hot water heating systems with a heating medium temperature of less than 150°C, and require that the system contain less than 0.05 g/m3 of oxygen. The plate radiator has two types of connectors with center distances of 500 mm and 300 mm. The joint center distance is 500 milligrams, the working pressure may be 6 ~ 9 kilograms/cm~2; In the joint
