How to install the electric butterfly valve to make it easy to use?
The electric butterfly valve is a small device that improves the quality of life in our daily life. Do you know that the electric butterfly valve can use metal in addition to materials? Although the metal electric butterfly valve sounds strange, it is still very popular in the industry. Today, I will explain to you how to install the metal electric butterfly valve to make it easier and more convenient to use!
1. During the construction of flexible valve pipeline, it must be kept in a natural state, and the product shall not be artificially deformed during installation.
2. When the pipeline medium is acid, alkali, oil, high temperature and other special materials, the valve with a gear higher than the working pressure of the pipeline shall be selected.
3. The flange connecting the valve shall be the valve flange or the flange conforming to GB/T9115.1 (RF).
4. The normal applicable medium of the valve is ordinary water with a temperature of 0-60 ° C. In case of special medium such as oil, acid and alkali, high temperature and other corrosive and hard conditions, the valve shall be made of the corresponding special resistant material, and shall not be used blindly or universally.
5. When the valve is used at the inlet and outlet of the water pump, it should be located at one side of the water pump. A metal reducing valve should be installed between the valve and the water pump, and it should be installed at the large diameter of the reducing valve.
6. When the pipeline displacement is greater than or equal to the maximum compensation amount of the valve, the number of valves shall be increased to parallel the displacement amount. It is strictly prohibited to adjust the out of tolerance of the pipeline, so that the valve is in the extreme deflection displacement and tendency state, and it is not allowed to exceed the limit (expansion, displacement, deflection, etc.) for high-rise water supply or suspended water supply. The pipeline shall be fixed on the hanger, bracket or anchor bracket, The valve shall not bear the weight and axial force of the pipeline itself.
7. When installing the valve, the screw rod of the bolt shall extend to the outside of the valve, and the bolts on each flange end face shall be tightened repeatedly and evenly by diagonal pressurization to prevent pressure deviation. Screw thread valves shall be tightened evenly with a standard wrench. Do not use an afterburner rod to force the valve to slip wires, slip edges and break, and regular inspection shall be carried out to avoid looseness, which may cause disc unseating or water seepage.
8. After the valve is subjected to pressure for the first time (such as installation and pressure test) or before it is used again after being stopped for a long time, the bolts shall be re pressurized and tightened before it is put into operation.
9. When using or storing the valve, avoid high temperature, ozone oil and acid-base environment. The pipeline used outdoors or facing the sun and wind shall be provided with a sunshade, and it is strictly prohibited to expose to the sun, rain or wind. It is strictly prohibited to paint or wind insulation materials on the valve surface. Due to the aging problem of products, they should be checked and replaced in time.
