Abstract
The utility model relates to a steady sealing gate valve, including valve body, flashboard, valve body inner wall one end is equipped with adjusts the tight platform in top, and the other end is equipped with the fixed station, the flashboard cooperatees the setting through the tight platform in regulation top in the valve body with the fixed station, be equipped with compression spring between fixed station and the flashboard, both ends are equipped with sealed ball about the flashboard, the even setting of sealed ball both sides about the flashboard, the flashboard setting still is equipped with the sealing washer at fixed you, adjust the tight platform in top including jacking bar and nut, the tight flashboard in jacking bar one end top, the other end stretches out valve body and fixed with the nut, the nut outside is equipped with the sealed cowling, the utility model discloses the scheme, the inefficacy that the long -term pressurized of unsteady disk seat did not float and causes has been solved again to state that the unsteady disk seat of both having overcome the original of the same kind valve products of pipeline such as perpendicular or slope was being pressed by flashboard and pressure medium for a long time, has stopped the phenomenon that valve seal became invalid, and it is reliable to have guaranteed that the end two way seal is imported and exported to the valve.
Description
Technical field
The utility model relates to a kind of steadily seal gate valve, belongs to gate valve technical field.
Background technique
Gate valve structure is simple, reliable performance, be widely used in petrochemical industry, refinery, petroleum gas, town gas etc. are inflammable, explosive dangerous situation, its casting of the valve products of former production is larger with the gap of valve body stationary platen well width, valve rod in opening-closing process except being subject to pressure medium effect, also be subject to the effect of flashboard and medium gravity, when valve is in vertical pipe installation or when filling in horizontal pipe side, the keying moment of valve is increased in opening-closing process, also the wearing and tearing between valve rod and Stem Mut transmission are accelerated, even cause transmission premature failure, therefore, needs make improvements.
Model utility content
The utility model object provides a kind of good sealing effect and stable steady seal gate valve to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of steadily seal gate valve, comprises valve body, flashboard; Described valve interior wall one end is provided with adjustment and holds out against platform, and the other end is provided with stationary platen; Described flashboard holds out against platform by adjustment and to match with stationary platen and be arranged in valve body; Compress Spring is provided with between described stationary platen and flashboard; The upper and lower two ends of described flashboard are provided with sealing ball; Described sealing ball is evenly arranged on the upper and lower both sides of flashboard; Described flashboard is arranged on fixing you and is also provided with seal ring; Described adjustment holds out against platform and comprises top-fastening rod and nut; Described top-fastening rod one end holds out against flashboard, and the other end stretches out valve body and fixes with nut; Seal closure is provided with outside described nut.
Preferably, described sealing ball array is in the upper and lower both sides of flashboard, and every side has 18 at least.
Preferably, described valve body is made up of stainless steel.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The steady seal gate valve of one of the utility model scheme, platform and stationary platen is held out against by establishing adjustment at valve interior wall, the upper and lower two ends of flashboard are provided with sealing ball, make valve in opening-closing process, the end face on flashboard can be close under pressure, reach and seal completely, flashboard holds out against platform by adjustment and to match with stationary platen and be arranged in valve body; Be provided with Compress Spring between stationary platen and flashboard and be used for damping and buffering, play stable effect; Flashboard is arranged on fixing you and is also provided with seal ring; Flashboard and medium gravity hold out against platform by adjustment and born, both the floating valve seat of the original similar valve products of pipeline such as vertical or inclination had been overcome for a long time by the state that flashboard and pressure medium press against, solve again the floating inefficacy caused of the long-term pressurized of floating valve seat, stop the phenomenon that valve seal lost efficacy, ensure that valve entrance end two way sealed is reliable.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the schematic diagram of a kind of steady seal gate valve of the present utility model;
