Abstract
The utility model discloses a valve sealing structure. The valve sealing structure comprises a valve body and a valve rod. The valve rod is connected into the valve body in a sleeved mode, the position, matched with the valve rod, of the upper portion of the valve body is provided with a filler chamber, the filler chamber is filled with fillers, the fillers are pressed by a gland, the outer circumferential surface, matched with the valve rod, of the gland and the inner circumferential surface, matched with the valve rod, of the gland are respectively provided with a groove, a sealing device is connected into each groove in a sleeved mode, and the gland is connected with the valve body through a pressing force adjusting device. The valve sealing structure has the advantages that the filler and sealing ring combination method is adopted, the traditional simplex sealing method is changed, sealing performance is better, reliability is higher, and sealing compensation can be achieved.
Description
Technical field
The utility model relates to valve field, particularly a kind of butterfly valve door sealing structure.
Background technique
The upper sealing configuration of prior art lower valve, is exactly the seal arrangement between valve rod and valve body top specifically, and what traditional sealing adopted is to compress gland sealed mode, and filler pre-pressing force is unadjustable can not realize sealing compensation, and sealing effect is bad.
Model utility content
For the deficiencies in the prior art, the utility model provides a kind of valve sealing structure.
To achieve these goals, the utility model solves the technological scheme that its technical problem adopts: a kind of valve sealing structure, comprise valve body and valve rod, described valve stem casing is connected in valve body, described valve body top is provided with filler chamber with valve rod cooperation place, in described filler chamber, be filled with filler, filler compresses by gland, on the inner peripheral surface matching with valve rod with gland on the outer peripheral surface coordinating with valve body on described gland, be equipped with groove, in groove, be socketed with seal arrangement, described gland is connected with valve body by impacting force adjustable apparatus.
Described impacting force adjustable apparatus is to be symmetrical in gland axis to be arranged on the stud between valve body and gland.
Described seal arrangement is O RunddichtringO, and the material of O RunddichtringO is nitrile butadiene rubber, fluorine rubber, silicone rubber, ethylene propylene rubber, neoprene, butyl rubber, teflon or natural rubber.
The beneficial effects of the utility model: this valve sealing structure of the present utility model adopts the dual compound mode of filler and seal ring, has changed traditional single sealing means, and sealability is better, more reliable, can realize sealing compensation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is local structure for amplifying schematic diagram of the present utility model.
