What is the difference between Daquan 6, the legend of pneumatic multi-level butterfly valve, and pneumatic butterfly valve? 4. Air leakage, which will lead to insufficient gas pressure and make the opening and closing of the mandatory valve difficult. Several reasons will lead to air leakage. (a) The destruction of the sealing gasket will cause air leakage in many mouths, and the sealing gasket will be removed and replaced; (b) If the source socket leaks, use raw tape to wrap it twice; (c) The connection between the coil and the valve body leaks. Loosen the anchor bolt, reinstall and tighten it
、 Technology creation The way to develop new pneumatic butterfly valve products mainly includes the following. The first way is to cooperate with universities and research institutions. The new valve products jointly developed by both parties have the international leading product level, which can compete with foreign brand valve products and have the international standard. Through scientific and technological creation, the gap and distance between domestic valves and international valves can be narrowed. If the enterprise has certain scientific and technological strength, it can develop and create new products by itself.
