Ball valves are generally limited by sealing materials, because ball valves are usually formed by some plastic materials, the main principle of ball valves is to rely on metal balls to adjust the gas and liquid under the action of the medium, mainly the extrusion between the metal ball and the plastic valve seat to achieve the effect of adjustment. Between the seats ...

The world's water treatment equipment giant United States Watts Industrial Group recently made a forecast that the total annual demand of China's valve market is not less than 10 billion yuan. According to the scientific concept of development, in order to ensure the coordinated development of the economy and improve the people's living standards in the future, China will inevitably build infrastructure, such as water.

The gas pressure reducing valve is to control the opening of the opening and closing parts in the valve body to adjust the flow of the medium, reduce the pressure of the medium, and at the same time adjust the opening of the opening and closing parts with the help of the pressure behind the valve, so that the pressure behind the valve is kept within a certain range, and the cooling water is sprayed in the valve body or behind the valve to reduce the pressure of the medium.

Use and Maintenance: 1. It is recommended that the user unit appoint a special person to be responsible for the use and maintenance 2. Regular maintenance 1-2 times a year is the best way for the solenoid valve to work reliably and live long. The following 4 conditions inside the solenoid valve are the reasons that hinder the normal operation of the solenoid valve and shorten the life of the solenoid valve. ⑴ ...

In the past operation of natural gas pressure regulating system, terminal equipment such as pressure regulating cabinets, pressure regulating boxes, and pipelines in the distribution network have always been a relatively weak part of the monitoring means. As a result, problems such as non-troubleshooting and emergency gas shutdown accidents also make consumers and operators feel painful. Meanwhile...
