How to deal with valve problems in buried small and medium-sized sewage treatment equipment? Author of the article: In the treatment of sewage daily, many of whom believe in the need for high cost of wastewater treatment management, improvement of water pollution in the ground so they buried the basis of small and medium sized sewage treatment equipment. However, residents in the suburbs or far from the city center are often missed out. Due to imperfect pipeline design, random emissions will occur, leading to more serious urban pollution. However, the current public attention to sewage treatment, coupled with national and urban institutional adjustments, has supervised urban emissions and investment in urban sewage treatment. The emergence of buried small and medium-sized sewage treatment equipment has made the public not only find that the investment cost is low, but also that the treatment efficiency is relatively high. The valves of buried small and medium-sized sewage treatment equipment are often used, and various problems will appear. Now I will introduce you to what to do if there are problems with the valves of buried small and medium-sized sewage treatment equipment? (1) Buried type The closing parts such as the gate of the medium and small sewage treatment equipment are damaged. The reason is the improper selection of materials or the valves on the used pipelines are often used as conditioning valves, and the high-speed moving medium forms the wear of the sealing surface. At this time we need to find out the cause of the damage and switch to other materials of closure. Avoid using the closed valve as a conditioning valve when there are many impurities in the high-pressure water or in the water. (2) The sealed chamber leaks. The main reason is that the most basic selection or filling method is incorrect, and the stem has quality problems. First of all, you should select the appropriate packing, and use the correct method to fill the packing in the sealed chamber. When the temperature of the conveying medium exceeds 100°C, oil-impregnated fillers are not used, but graphite fillers with higher heat resistance selectivity are selected among all materials. (3) The closure is not tight. Before the valve is installed, there are regulations to follow the installation, for example, to clean up the dirt in the inner cavity of the valve, and there are welding slag, rust, mud, sand or other impurities left by the work of the machine, which is easier to cause scratches on the sealing surface Defects such as dents, etc. cause valve failure of water treatment equipment. Therefore, it is necessary to strictly abide by the device regulations to ensure the quality of the device. If the manufacturing precision of the valve itself is not good enough, the seal and the closing part (the valve plate and the valve seat) will not cooperate closely, and it is necessary to repair or replace it at this moment. Excessive force when closing the valve will also cause damage to the sealing parts of the water treatment equipment. Use proper force when operating. This is the end of the introduction on how to deal with problems with the valves of the buried small and medium-sized sewage treatment equipment. Each component of the buried small and medium-sized sewage treatment equipment will have some problems after long-term use. Observe more when using it, and don't wait for serious problems. It is resolved. The maintenance of the grille decontamination machine in the buried small and medium-sized sewage treatment equipment should also be carried out frequently.
