Product use A40 with radiator valve spring full-Kai closed on the basis of A42 radiator valve on the increase, making it easier to heat the spring Shandong A40Y-C valve, the valve to improve the use of temperature. [Features] 1, the entire Kai structure, large displacement 2, the valve at the kick plate has three parts, with the radiator, to improve the use of temperature 4, setting the pressure valve Shandong small deviations up to ± 3% 5, blowdown ≤15% 6, high quality spring steel safety valve to ensure the longevity and stability of the seven springs, valve and seat planar structure is easy to install and reworked valve repair and maintenance should note the following construction installation points 1), the installation position, altitude, direction and export must meet the design requirements, pay attention to the direction of flow of the medium should be consistent with the direction of the arrow on the valve body, the connection should be firmly tight. 2), must be visually checked before installing the valve, the valve plate should comply with the provisions of the current national standard GB 12220 "Universal Valve logo." For working pressure greater than 1.0 MPa and the role played off the main pipe valves should be installed before the strength and rigorous performance tests, passing behind the prospective use. Strength test, the test pressure is 1.5 times the nominal duration of not less than 5min, the valve housing, packing should be no leakage as qualified. Tightness test, the test pressure for the nominal pressure of 1.1 times; the test duration in line with the requirements of GB 50243 1. All kinds of safety valve should be installed vertically.
