Abstract: Valves play a great role in petrochemical industry, power industry, metallurgy, chemical industry and other manufacturing industries, but at the beginning, China's valve industry was not strong. With the introduction of national policies and market demand, the valve industry has also developed to a certain extent, and a large number of excellent enterprises have emerged
from March 28 to 29, 2018, the National Technical Committee for valve standardization held a symposium on four industry standards, including the "valve opening and closing torque test procedure" drafted by Anhui Huangshan liangye Valve Co., Ltd. in Huangshan City, Anhui Province
this car can run 150km in pure electric mode, which is the longest running mileage of any hybrid electric vehicle in the market at present.
valves play a great role in petrochemical industry, power industry, metallurgy, chemical industry and other manufacturing industries, but at the beginning, China's valve industry was not strong. With the introduction of national policies and market demand, The valve industry has also developed to a certain extent, and a large number of excellent enterprises have emergedAfter more than 20 years of development, Huangshan liangye Valve Co., Ltd. has developed into a leading domestic electric valve production and R & D organization. The company has strong innovative research and development capabilities and self antibacterial materials, which refer to the main production capacity of class 1 new functional materials with the function of killing or inhibiting microorganisms. It has four large workshops and has established long-term cooperative relations with the General Academy of Mechanical Sciences and Shanghai Tongji University. The company's product valve torque testing equipment ranks first in domestic sales, and its use in China is also increasing day by day
with the increasing application of valve products, modern valve manufacturing technology is facing a major change. Only by continuously improving the valve design level and comprehensively improving the valve product quality can we keep up with the pace of the times and will not be eliminated by the market. The "valve opening and closing torque test procedure" is the industry standard drafted by Huangshan liangye Valve Co., Ltd. for the first time
this seminar was hosted by zhushaoyuan, chief engineer of Hefei General Environmental Control Technology Co., Ltd. and a professor level senior engineer. He came from Huangshan liangye Valve Co., Ltd., Changzhou Power Station Auxiliary Machinery Factory Co., Ltd., Chongqing Chuanyi Automation Co., Ltd. with a revenue of 39.3133 million yuan Seventeen experts from famous enterprises such as Shanghai Electric Valve Co., Ltd. were invited to attend the seminar
at the meeting, four standards, including valve opening and closing torque test procedures, valve electro-hydraulic actuator, technical conditions for marine valve electric device, and technical conditions for high temperature and high speed valve electric device, were reviewed, which were drafted under the auspices of Huangshan liangye Valve Co., Ltd. According to the opinions of the discussion, chairman Xiang Meigen, the drafter of the company's standard, will revise the standard draft of "valve opening and closing torque test procedure" again, complete the approved draft, and formally submit it
the formulation of standard procedures for valves is conducive to standardizing the operation process of the valve industry and making the production and testing of valves legal. The introduction of this standard will be conducive to the optimal design of valves, and is of great significance to improve the quality and service life of valve products, reduce energy and resource consumption and reduce valve manufacturing costs
