Pipeline anti-fouling cut-off valve is a safety device for preventing back-flow pollution in drinking water pipelines to ensure the hygiene and safety of drinking water.
Structure: The safety type anti-fouling cut-off valve is composed by adding a drain between two check valves. The upper drain chamber is connected to the inlet end of the primary check valve with a high pressure hose. First, the two-stage check valve is mainly composed of a valve body, a valve cover, a valve flap, a gasket, and a spring. The drain is mainly composed of a valve body, a valve cover, a diaphragm, a valve flap, a sealing plate, a valve core, a valve seat, and a spring. Ordinary anti-soiling partition valve is made up of two check valves in series.
Working principle: The anti-fouling partition valve is made up of two check valves connected in series. When one of the seals is broken, the other seals to prevent backflow. However, when the two check valve seals are destroyed at the same time, they lose the check-return function, and their safety and reliability are relatively poor, and the working principle is relatively simple. The anti-pollution cut-off valve is provided with a drain in the middle of the common type, so that even if the two check valves are sealed and destroyed at the same time, they can also play a role in preventing back-flow pollution.

Working Principle
Jig machines need water to work, and it loosens materials in vertical alternative water-flows, and it forms different layers of materials of different densities and discharges both layers from up and down discharging ports separately. The basic composition of jigger is jigging chambers, also called jigging boxes, and there are screens in each chamber.
Water and raw ore will be fed from one end of the jigger screen, the ore granules will move in the vertical alternative water-flows. Layers will be formed because of density difference of materials. The minerals with small density will be in the up layer and will flow together with the up pulp flow while material with bigger density will be in the down layer and will discharged from the down discharging port as jigging concentrate.
ApplicationThis jig machine Can achieve a good result in processing such as placer gold, diamond, tungsten, iron, tin, hematite, cope, tantalum-niobium, titanium, manganese, barite, zirconium, chrome and gemstone etc.
Main Feature
