valve

Check valve installed in the piping system, and its main role is to prevent the media back, A check valve is opened to rely on media pressure and the closure of the automatic valve. Widely used in Taiwan is H44 - flange connecting Kai Xuan - H41-check valve and flange connecting movements valve This traditional bulky big check valves, fluid resistance, the valve closes when the water hammer pressure, installation, maintenance difficulties, short service life. I companies check valve against the traditional structure of the issue, the United States and Germany API standard DIN standards as the basis, I combined company over the years valve test research, development design, processing and manufacturing, and other aspects of rich experience, Development of the H76-to-flap folder rotary valve and Kai-H71-to-folder lifts valve series products, by the petrochemical, metallurgical, power, light industry, food industry enterprises and manufacturers of complete sets of equipment used for years, the result is good, was well received by users. Products by the provincial science and technology achievement appraisal, technical innovation, leading to the domestic level. China is the fourth and new technologies and products Expo in Kuala Lumpur, was recommended for high-quality IT products in Zhejiang province. I am responsible for the drafting of the national machinery industry standards JB/T 8937-1999 "folder valve" in the whole State promulgation and implementation of new technologies for the promotion and application of the industry and to the technological progress made positive contributions. Characteristics of a structure, the structure of the short length, the length of the structure is only the check valve flange traditional 1/4~1/8; 2, The small size, light weight, the weight only to the traditional check valve flange 1/4~1/20; 3, valve valve fast, Small water hammer pressure; 4, horizontal or vertical pipe can be used by pipeline, easy installation; 5, the flow smooth, fluid resistance is small; 6, movement sensitive and good sealing performance; 7, a short trip flap valve, valve clearance impact small; 8, the overall structure, a simple compact, Modeling beauty; 9, long life and high reliability. Use of his spin-valve Kai apply to seating PN1.0MPa~42.0MPa. Class150~2500; public Path DN15~1200mm said. NPS1/2~48; -196~540 ° C operating temperature of the road for the media to prevent backflow. Through the use of different materials and can be applied to water, steam, oil, nitric acid, acetic acid, a strong oxidizing media and urea, and other media.
