Ceramic sealing discs, control discs, steering valves and other products, the working surface has a diamond-like hardness, acid and alkali solvent resistance, excellent reliability and long life. Solids carried in drinking water such as sand, rust and lime are ground between the surfaces of the ceramic disc sliding without affecting the sealing performance of the valve plug. After millions of motion cycles, there will be no signs of wear and will continue to precisely control the required water volume and water temperature in the spool – even in harsh conditions such as supply system pressure ratios and water temperature fluctuations.

The subject of the "Report on the Status of Automatic Monitoring Equipment for Pollutant Water Quality at Home and Abroad" was undertaken by the China National Environmental Monitoring Center and assisted by the Hubei Provincial Environmental Monitoring Center.
At present, there are many domestic manufacturers of pollution source water quality automatic on-line monitoring systems, varying levels of technology, large differences in production capacity, and different monitoring methods. Therefore, in order to ensure the realization of pollution source emission reduction tasks, understand the development status of China's pollution source automatic water quality monitoring instrument industry, develop advanced monitoring equipment with China’s independent intellectual property rights, and improve the quality of domestic monitoring equipment and monitoring technology, and carry out It is of great significance to study the status quo and development direction of pollution source automatic water quality monitoring instruments.
The topics "Report" mainly include: the development basis, development history, and succession process of China's pollution source automatic water quality monitoring equipment; China's pollution source automatic water quality monitoring technology development law and lessons learned; pollution source water quality automatic monitoring equipment manufacturing technology gap and pollution source water quality automatic Monitoring instrument management analysis. The review panel unanimously held that the topic organization and management are good, the progress is smooth and clear, and it can reflect the current status of China's pollution source automatic water quality monitoring instruments, and has guiding significance for the development of China's water quality automatic monitoring equipment.
At the meeting, the Director of Monitoring Department of the Ministry of Environmental Protection, Yan Yanchao pointed out: "To carry out research on this project, analyze the status quo of domestic and foreign water environment monitoring instruments, and put forward the macroscopical development direction of China's water environment monitoring instruments, which is conducive to the development of China's pollution source automatic monitoring equipment industry. At the same time, through finding out the status of China's production enterprises of pollution source automatic water quality monitoring instrumentation industry, we identified gaps, provided technical support for the regulation of China's pollution source automatic water quality monitoring instrument industry management, and also put forward specific recommendations for China's 'Twelfth Five-Year' environmental planning. Suggestions."
Zhang Zhixiang, head of the Hubei Provincial Environmental Monitoring Center, said: “According to the amendments proposed by the group of experts, the industry’s experience in automatic monitoring equipment for water quality of pollution sources should be summed up to find out the law of development, further clarify the objectives and direction of development, and conscientiously improve the report of the project. Content, to the Ministry of Environmental Protection to deliver a satisfactory answer."
Recently, the research team will further improve the content of the report. After inviting experts to demonstrate, they will report to the Ministry of Environmental Protection for an overall assessment of the project. The results of the project will provide the basis for the next step in the standardized management of pollution source automatic water quality monitoring equipment industry.
We have been supplying hundreds of ceramic seal disc for domestic and overseas client, including a series of standard designs and a variety of customized ones. With our seasoned know-how and experience to the industry, we deeply understand how to control the critical dimensions, how to keep the quality consistence.
These ceramic seal disc are mainly used in faucet valve, water diverter, water pump, oil pump and gas pump as a key component inside the sealing system.
Pollution source water quality monitoring instrument specification strengthened
On December 1, 2010, the Mid-term Evaluation Conference of the Ministry of Environmental Protection's "Report on the Status of Automatic Monitoring Equipment for Pollutant Water Quality at Home and Abroad" was held in Wuhan. Leaders and experts from the Ministry of Environmental Protection, China National Environmental Monitoring Center, Hubei Province Environmental Monitoring Center Station, Wuhan City Environmental Monitoring Center Station, China University of Geosciences (Wuhan), and Wuhan Juzheng Environmental Protection Co., Ltd. heard the report of the project and proposed amendments to the issue.
