Abstract
The utility model discloses a high-temperature-resistant butterfly valve which comprises a valve body, a valve rod and a seal ring, wherein the valve body is cylindrical and internally provided with a dish plate; a sealing filler is arranged on a part, contacted with the valve rod, of the valve body; an external rolling bearing is arranged on the valve rod; and the sealing filler is made of a high-temperature-resistant material. The high-temperature-resistant butterfly valve has the benefits of better sealing property and longer service life, can be used for a high-temperature medium.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of good airproof performance, high temperature resistant butterfly valve.
Background technique
The high temperature resistant butterfly valve seal performance of tradition is low, and adopts general material to process, and non-refractory should not be used for high temperature media, and the dress sliding bearing was short working life in traditional high temperature resistant butterfly valve adopted.
Summary of the invention
To the deficiency of existing technology, the utility model provides a kind of good airproof performance, high temperature resistant butterfly valve.
To achieve these goals, the technological scheme taked of the utility model is:
A kind of high temperature resistant butterfly valve comprises valve body, valve rod and seal ring, and valve body is cylindrical, and built-in dish plate; Be provided with stuffing box packing with the valve rod contact segment on the valve body.
Adopt the external mounted rolling bearing on the said valve rod.
Said stuffing box packing adopts high temperature resistant material to process.
The beneficial effect of the utility model: better tightness can be used for high temperature media, longer service life.
Description of drawings
Fig. 1 is the high temperature resistant butterfly valve schematic representation of the utility model.
Embodiment
As shown in the figure, a kind of high temperature resistant butterfly valve comprises valve body 1, valve rod 2 and seal ring 4, and valve body 1 is cylindrical, and built-in dish plate 3; Be provided with stuffing box packing 5 with valve rod 2 contact segments on the valve body 1.Adopt external mounted rolling bearing 6 on the said valve rod 2.Said stuffing box packing 5 adopts high temperature resistant material to process.Dish plate 3 is driven by valve rod 2, turns over 90 ° and just can accomplish once keying.Change the deflection angle of dish plate 3, get final product the flow of control media.
