Abstract
The utility model relates to a 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 guide rail, the flashboard cooperatees the setting through the tight platform in regulation top in the valve body with the guide rail, 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 the guide rail end, 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 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 guide-track groove 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 is the seal gate valve providing a kind of good sealing effect in order 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 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 guide rail; Described flashboard holds out against platform by adjustment and to match with guide rail and be arranged in valve body; 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 guide rail end 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:
A kind of seal gate valve of the utility model scheme, platform and guide rail 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 guide rail and be arranged in valve body; Flashboard is arranged on guide rail end 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 seal gate valve of the present utility model;
Wherein: 1, valve body; 2, flashboard; 3, adjustment holds out against platform; 4, guide rail; 5, ball is sealed; 6, seal ring; 7, top-fastening rod; 8, nut; 9, seal closure.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing 1 is a kind of seal gate valve described in the utility model, comprises valve body 1, flashboard 2; Described valve body 1 inwall one end is provided with adjustment and holds out against platform 3, and the other end is provided with guide rail 4; Described flashboard 2 holds out against platform 3 by adjustment and to match with guide rail 4 and be arranged in valve body 1; Described flashboard about 2 two ends are provided with sealing ball 5; Described sealing ball 5 is evenly arranged on flashboard about 2 both sides; Described flashboard 2 is arranged on guide rail 4 end and is also provided with seal ring 6; Described adjustment holds out against platform 3 and comprises top-fastening rod 7 and nut 8; Described top-fastening rod 7 one end holds out against flashboard 2, and the other end stretches out valve body 1 and fixes with nut 8; Seal closure 9 is provided with outside described nut 8; Described sealing ball 5 array is in flashboard about 2 both sides, and every side has 18 at least; Described valve body 1 is made up of stainless steel.
The utility model scheme is by establishing adjustment to hold out against platform 3 and guide rail 4 at valve body 1 inwall, flashboard about 2 two ends are provided with sealing ball 5, make valve in opening-closing process, the end face on flashboard 2 can be close under pressure, reach and seal completely, flashboard 2 holds out against platform 3 by adjustment and to match with guide rail 4 and be arranged in valve body 1; Flashboard 2 is arranged on guide rail 4 end and is also provided with seal ring 6; Flashboard 2 and medium gravity hold out against platform 3 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 2 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.
Below be only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation.The technological scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope.
