Description

Technical Field

[0001] The utility model relates to a valve opener and closer, in particular to a manual and electric dual-purpose valve opener and closer. Background Art

[0002] Nowadays, small-caliber, fixed valves are basically solenoid valves with PLC control, which do not require manual operation. However, large valves and outdoor valves, such as those in urban areas, such as concealed underground wells, bridgeside pipeline valves and other public areas, as well as valves in areas without electricity near the valves, still need to be opened manually. When opening the valve manually, a metal valve opener and closer is generally used. This type of tool can solve the safety problems of personnel working in the well and the problem of poor underground operations, but it is inconvenient for the following situations: 1. Large plants or long sections need to be transported, which is relatively heavy; 2. When the valve adjustment has a linkage effect and needs to be adjusted repeatedly, people need to carry a pole back and forth to several different valve wells for operation; 3. The number of turns required to open valves above DN300 is relatively large, especially for valves above DN1000, which usually take 5-10 minutes to open, which is inefficient; 4. Since the length of this type of pole is fixed, if the valve depth is different, usually more than one pole is required. Utility Model Content
