Abstract
Description
Technical Field
[0001] The utility model relates to the field of stop valves, in particular to a stop valve with good stability. Background Art
[0002] Globe valves, also known as gate valves, are forced-seal valves. Therefore, when the valve is closed, pressure must be applied to the disc to prevent leakage. When the medium enters the valve from below the disc, the operating force must overcome the friction between the stem and packing, combined with the thrust generated by the medium's pressure. The force required to close the valve is greater than the force required to open it, so the valve stem diameter must be large; otherwise, it can cause stem bending. Connections are categorized into three types: flange, threaded, and welded.
[0003] During the long-term water flow cutoff process, the existing stop valve is prone to loosening of the internal structure of the stop valve due to external vibration, thereby causing water leakage. Therefore, a stop valve with good stability is proposed. Utility Model Content
