Hengda mine manufacturers tell you the importance of the valve

Hengda mine manufacturers tell you the importance of the valve, in the day-to-day operations of the mine, each device is connected through the pipeline to complete the beneficiation operations, while the valve is a throttling, cut off the role.

Valve and beneficiation production line is closely related to high-quality valves can be greatly reduced, or even completely avoid the valve led to the smooth flow of the pipeline. The design of reasonable quality evaluation valve is one of the standards, and the same important standard is the valve material, the use of wear-resistant materials, the better the quality of the valve. In particular, the high frequency of the closed pipeline parts, the valve's wear resistance is a test.

The valve has a wide variety of materials, such as metal valve, cast iron, cast steel, alloy steel, titanium alloy material of the valve; non metal valve, such as plastic, enamel, ceramics, glass and steel valves; and the metal body lining + valve, such as valve shell for metal surface contact with the medium for the internal lining. A rubber lining, plastic, ceramics etc.. Different materials have different application conditions, and wear resistance will be different depending on the media.

In the beneficiation production line with rubber valve is the most common, because the valve as a part of the pipeline, the material impact and wear by the operation process, so it is need to wear reliable performance; at the same time, the valve opening and closing when needed to ensure that both does not leak, devascularization can also completely closed, so good the elasticity is also important. Rubber is a long chain of molecules, so it is not only elastic, but also difficult to break. It can wear and stretch well, so it is the first step of the lining of the valve.
