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 to improve the valve's operating 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 deviation is small, up to ± 3% 5, hoist pressure ≤15% 6, high quality spring steel to ensure the longevity and stability of the spring 7, the installation and maintenance of the valve and seat planar structure is easy to repair and re-processing of the safety valve should note the following construction, installation points 1 ), the installation location, height, and export orientation must meet the design requirements, pay attention to the direction of flow of the medium should be consistent with the direction of the standard valve Shandong arrow on the 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 valve on the main pipe valve, should be the strength and rigorous performance tests before installing the valve in Weifang, 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. Operating items found signs of a leak valve safety valve A40YC offer, should be replaced or maintenance. Prohibit the use of increased load (eg adjusting screw on the lever or safety valve lever to add a heavy and so over-tighten the spring-loaded safety valve) methods to eliminate leaks. Regularly check the operation of the valve leaks, jamming and spring rust and other irregularities, and to observe the adjustment screw cover and adjusting ring set screw lock nut is loose, if a problem should promptly take appropriate measures. A40YC valve manufacturers, valve, valve type Everbright Everbright Limited provided by Shandong valve. Valve Co., Ltd.
