Abstract
The utility model relates to an anhydrous high temperature resistant valve which applies to a warm air pipe. The utility model comprises a valve body, a valve cap, and a valve plate. The valve plate is composed of a valve plate body, and a guide rod. One end of the valve plate body is provided with the guide rod, the guide rod is led out from a guide hole of the top of the valve cap, and the guide rod is connected with a driving device. The utility model completely gets rid of a cooling system mode of water circulation of a hot blast valve. The utility model uses an improved technical proposal, and the abuse of the prior art can be eliminated. The utility model has the advantages that the structure can be simplified, the performance can be improved, the service life of the valve can be extended, and large amounts of water resources can be saved.
Description
The utility model relates to the anhydrous high temperature resistant valve that a kind of hot air duct is used.
In order to prevent that long-term work is prone to high temperature oxidation and thermal fatigue phenomenon under the hot environment, used valve is continued to use the cooling of the water cycle type of cooling always on the hot air duct, though can obtain the part cooling-down effect, but water resource waste is serious, and water-cooling tube is prone to incrustation scale, and water cooling usually is obstructed, and does not reach the cooling purpose, steel pipe or steel plateelement also cracking phenomena can occur, and valve is scrapped still very serious.
The utility model is exactly to have the defective that valve exists now for removing, and abandons the water cycle type of cooling, and adopts heat-resistant material to design, prevent that cracking phenomena from appearring in steel pipe or steel plateelement, improve the valve working quality, thereby delay valve working life, for this reason, develop a kind of anhydrous high temperature resistant valve.
Anhydrous high temperature resistant valve comprises valve body, valve gap and valve plate.Valve body is made of shell, liner and stuffing box gland, and valve gap also has shell and liner, and valve body and valve gap connect into integral body.The valve plate that is positioned at body cavity is made of valve plate body and guide rod, the sealing of should fitting when valve plate body end face contacts with valve body liner stuffing box gland end face, valve plate body one end is established guide rod, guide rod is drawn from valve gap top pilot hole, connect drive unit, guide rod promote to open or cuts out hot air duct by drive unit, i.e. switch valve, and the guide rod pilot hole place of valve gap is provided with seal ring.
The drawing of accompanying drawing is described as follows:
Fig. 1 is anhydrous high temperature resistant valve plan view;
Fig. 2 is anhydrous high temperature resistant valve left view.
Embodiment below in conjunction with this anhydrous high temperature resistant valve of accompanying drawing introduction.
This anhydrous high temperature resistant valve is made up of valve body, valve gap and valve plate.Valve body adopts foundry goods or weldment shell (1), inwall cast light heat-insulating material liner (2), and valve body liner (2) warm-air pipe road junction one side is established stuffing box gland (3), and its bottom, lower end is provided with the dedusting hole, has the valve body lower cover plate to close.Valve gap shell (4), the same valve body of liner (5) material, the two casting liner all can adopt reinforces the nail reinforcing.
Valve plate is positioned at body cavity, constitute by valve plate body (6) and guide rod (7), valve plate body (6) is made disc or square disc shape, guide rod (7) is formed by connecting by two sections, hypomere is made by high alumina matter heat-resistant material, and epimere is a refractory metal material, is convenient to the transmission guiding, guide rod (7) is drawn from valve gap top pilot hole, and the pilot hole place is provided with seal ring (8).
The utility model has been abandoned the Hot-blast valve water cycle type of cooling fully, adopts and improves technological scheme, has eliminated the drawback of prior art, simplified structure improves performance, has not only delayed valve working life, and saved great lot of water resources, economic and social benefits are obvious.
