Description
Technical field
The utility model belongs to the connection sealing device field of valve, relates generally to a kind of flange sealing structure of valve.
Background technology
The sealing property of valve is one of leading indicator of examination valve mass quality. At present, on market, apply the more sealing for face-flange, due to this sealing surface and pad contact area larger, as improper in pretension, pad is easily extruded sealing surface; Meanwhile, be difficult for compressing, sealing property is poor, inapplicable in the situation that pressure is high. In the time of dismounting valve, pad is also not easy to take out. Therefore how to simplify assembling and the dismounting of flange sealing structure, and strengthen sealing effectiveness, to adapt to different user demands, become those skilled in the art's problem demanding prompt solution.
Summary of the invention
Problem to be solved in the utility model regulates the easily flange sealing structure of the valve of taking-up of pad while being to provide a kind of easily manufactured, easy assembling, good sealing effect, dismounting.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of flange sealing structure of valve, comprise connecting bolt, nut, upper flange, lower flange, adjusting pad and sealing ring, described lower flange is arranged at bottommost, described upper flange is arranged on lower flange, space between described upper flange and lower flange becomes lenticular seal groove, and described adjusting pad is the structure matching with lenticular seal groove, and described sealing ring is " O " type.
Described connecting bolt is through upper flange and import lower flange into.
Described nut is arranged on the surface away from lower flange of upper flange.
Described adjusting pad is politef material, diameter 2mm, thickness 1mm.
Described sealing ring is quality of rubber materials, and diameter is 1.8mm.
Owing to adopting technique scheme, the space between upper flange and lower flange becomes lenticular seal groove, and regulating pad is the structure matching with lenticular seal groove, and lenticular type of attachment, in the time of dismounting valve, regulates pad easily to take out. Sealing ring is " O " type, easily manufactured, after assembling, can produce enough radial compression deformation, needn't axially load the sealing effectiveness that can reach good. When assembling and setting, regulate the relative position of pad adjustable valve bar and valve gap. In the time that upper flange is connected with lower flange, regulating pad to be placed in groove, until flange face contacts completely, make sealing effectiveness reliable. Regulating pad is politef material, and the scope of application of its temperature is from-50 DEG C to 200 DEG C, and self lubricity is good, and coefficient of friction is low, and no hygroscopicity can meet the instructions for use of varying environment; Surperficial not viscosity prevents the adhesion of other impurity, affects sealing effectiveness.
The beneficial effects of the utility model are: when easily manufactured, easy assembling, good sealing effect, dismounting, regulate the easily advantage of the valve of taking-up of pad.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Detailed description of the invention
As shown in Figure 1, the flange sealing structure of a kind of valve of the utility model, comprise connecting bolt 1, nut 2, upper flange 3, lower flange 4, regulate pad 5 and sealing ring 6, described lower flange 4 is arranged at bottommost, described upper flange 3 is arranged on lower flange, space between described upper flange 3 and lower flange 4 becomes lenticular seal groove, and described adjusting pad 5 is the structure matching with lenticular seal groove, and described sealing ring 6 is " O " type. Described connecting bolt 1 is through upper flange and import lower flange into. Described nut 2 is arranged on the surface away from lower flange of upper flange. Described adjusting pad 5 is politef material, diameter 2mm, thickness 1mm. Described sealing ring 6 is quality of rubber materials, and diameter is 1.8mm.
Space between upper flange 3 and lower flange 4 becomes lenticular seal groove, and regulating pad 5 is the structure matching with lenticular seal groove, and lenticular type of attachment, in the time of dismounting valve, regulates pad 5 easily to take out. Sealing ring 6 is " O " type, easily manufactured, after assembling, can produce enough radial compression deformation, needn't axially load the sealing effectiveness that can reach good. When assembling and setting, regulate the relative position of pad 5 capable of regulating valve rods and valve gap. In the time that upper flange 3 is connected with lower flange 4, regulating pad 5 to be placed in groove, until flange face contacts completely, make sealing effectiveness reliable. Regulating pad 5 is politef material, and the scope of application of its temperature is from-50 DEG C to 200 DEG C, and self lubricity is good, and coefficient of friction is low, and no hygroscopicity can meet the instructions for use of varying environment; Surperficial not viscosity prevents the adhesion of other impurity, affects sealing effectiveness.
Above the flange sealing structure of a kind of valve provided by the utility model is described in detail. Applied specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment is just for helping to understand method of the present utility model and core concept thereof. Should be understood that the those of ordinary skill in art field, do not departing under the prerequisite of the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
