By adopting technique scheme, in described valve body body, vacuum heat resistant layer is set, can utilize the adiabatic feature of vacuum, reduce the thickness that contacts of valve body body and medium, and the conduction to medium temperature, thereby greatly reduce the heat leakage of medium, not needing to pass under the prerequisite of steam, also can play the effect of certain insulation, both economized on resources, also reduced the requirement to valve body body intensity, manufacture cost reduces; In addition, vacuum heat resistant layer is set, has also reduced and manufactured described valve body body required metallic material and own wt, economical and practical.
The utility model is further set to: described valve body body comprises valve outer wall, and medium channel comprises channel wall, and described vacuum heat resistant layer is located between valve outer wall and channel wall.
By adopting technique scheme, because channel wall is the position of direct contact medium, described vacuum heat resistant layer is located between valve outer wall and channel wall, be the most preferably scheme that described vacuum heat resistant layer plays insulation, effect of heat insulation; And, in to the structural strength of flange plate and with the consideration of the join strength of pipeline, at the two ends of channel wall, the position of flange plate does not arrange vacuum heat resistant layer.
The utility model is further set to: described vacuum heat resistant layer comprises vacuum cavity and end cap, described vacuum cavity and this body by integral forming of valve body.
By adopting technique scheme, the vacuum heat resistant layer being formed by vacuum cavity and end cap, processing, easily manufactured, directly casting, reduces machining or manufacturing procedure, has reduced cost and has reduced production time to a certain extent; Described vacuum heat resistant layer can directly vacuumize, form when casting, also can be according to actual conditions, after described valve body body casting, recycling special machinery vacuumizes, finally use end bracket enclosed, and integrated vacuum cavity, can guarantee the structural strength of described valve body body.
The utility model is further set to: described channel wall is provided with ceramic heat resistant layer.
By adopting technique scheme, because stupalith heat-conducting property is generally lower than metal, ceramic heat resistant layer is set and can further reduces scattering and disappearing of medium temperature; In addition, utilize good corrosion-resistant, high temperature resistant, the wear-resisting erosive wear resistance that undermines of stupalith, alternative metals material forms channel wall, makes valve body body longer service life.
The utility model is further set to: the bottom of described valve stem passage is provided with for supporting the supporting base of valve body body.
By adopting technique scheme, supporting base is set and not only facilitates putting of described valve body body, by valve body body vertical display, reduce occupation area, also facilitate workman to assemble, when needed, can be at any time that valve body body is upright.
Accompanying drawing explanation
Fig. 1 is the valve body embodiment's of the utility model insulation butterfly valve structure exploded perspective view.
Reference character: 1, valve body body; 11, medium channel; 111, channel wall; 111, ceramic heat resistant layer; 12, upper valve rod passage; 13, lower valve rod passage; 14, flange plate; 15, vacuum heat resistant layer; 151, vacuum cavity; 152, end cap; 16, valve outer wall; 17, supporting base.
Embodiment
With reference to Fig. 1, the valve body embodiment of the utility model insulation butterfly valve is described further.
As shown in Figure 1, a kind of valve body that is incubated butterfly valve, comprise valve body body 1, described valve body body 1 comprises medium channel 11, upper valve rod passage 12, lower valve rod passage 13 and at least two flange plate 14, described medium channel 11 is located at valve body body 1 inside, described upper valve rod Channel 12-Bit is in medium channel 11 upper ends, lower valve rod passage 13 is positioned at medium channel 11 lower ends, described two flange plate 14 are located at respectively medium channel 11 both sides, described valve body body 1 is provided with for insulation, heat insulation vacuum heat resistant layer 15(it should be noted that herein, the material of described valve body body 1 and wall thickness should guarantee practicability and the working life of self).
At the interior vacuum heat resistant layer 15 that arranges of described valve body body 1, can utilize the adiabatic feature of vacuum, reduce the thickness that contacts of valve body body 1 and medium, and the conduction to medium temperature, thereby greatly reduce the heat leakage of medium, do not needing to pass under the prerequisite of steam, also can play the effect of certain insulation, both economized on resources, and also reduced the requirement to valve body body 1 intensity, manufacture cost reduces; In addition, vacuum heat resistant layer 15 is set, has also reduced and manufactured described valve body body 1 required metallic material and own wt, economical and practical.
Described valve body body 1 comprises valve outer wall 16, and medium channel 11 comprises channel wall 111, and described vacuum heat resistant layer 15 is located between valve outer wall 16 and channel wall 111.
Because channel wall 111 is positions of direct contact medium, described vacuum heat resistant layer 15 is located between valve outer wall 16 and channel wall 111, be the most preferably scheme that described vacuum heat resistant layer 15 plays insulation, effect of heat insulation; And, in to the structural strength of flange plate 14 and with the consideration of the join strength of pipeline, at the two ends of channel wall 111, the position of flange plate 14 does not arrange vacuum heat resistant layer 15.
Described vacuum heat resistant layer 15 comprises vacuum cavity 151 and end cap 152, and described vacuum cavity 151 is one-body molded with valve body body 1.
