Potassium sulfate is a common potash fertilizer. It can improve crops ability of drought resistance, cold resistance, lodging resistance,and pest disease resistance. It can also promote flowering and fruiting, and better use of nitrogen to increase protein content, and promote the production of sugar and starch. Especially suitable for tobacco, sugarcane, potato, sweet potato, grape, tea tree and other high potassium crops and sulfur-like cruciferous crops (such as rapeseed, beans, etc.) .Increase the strength, fineness,color purity of cotton and hemp crop fiber.

Hydraulic control valve features, repair and maintenance
Hydraulic control valve is a water pressure control valve, hydraulic control valve consists of a main valve and its attached conduit? Pilot valve? Needle valve? Ball valve and pressure gauge and other components. According to the purpose of use? Function and place can be evolved into a remote control float valve? Pressure relief valve? Slow closing check valve? Flow control valve? Relief valve? Hydraulic electric control valve, pump control valve. The filter must be installed in front of the hydraulic control valve and it should be easy to drain the water. Hydraulic control valve is a self-lubricating water valve body, without additional oil lubrication, in case of damage to the main valve components, according to the following instructions for disassembly. (Note: The general consumption of damage within the valve products for the diaphragm and o-ring, other internal parts little damage) 1. The main valve before and after the end gate valve closed. 2. Release the pipe fitting screw on the main valve cover to release the pressure in the valve. 3. Remove all screws, including the nuts of the necessary brass in the control line. 4. Take the valve cover and spring. 5. The axis, diaphragm, piston and other removed, do not damage the diaphragm. 6. After the above items are removed, check the diaphragm and â—‹ ring is damaged; if no damage do not subcontract their own internal components. 7. If it is found that the diaphragm or o-ring is damaged, please loosen the nut on the shaft core, break out the diaphragm or ring by Zhejiang, and then replace it with a new diaphragm or o-ring. 8. A detailed examination of the main valve internal valve seat, shaft and other damage if any other debris in the main valve to clean it out. 9. In reverse order is the replacement of the main components of the valve assembly, pay attention to the phenomenon of the valve can not be jammed.
