Abstract
The utility model provides a hot air valve plate, which comprises a hydrosphere, and ceramic coating arranged at the outer surface of the hydrosphere. According to the hot air action to the valve plate, the ceramic coating is arranged at the lower part of the hydrosphere in the arrange of the included angle 120 degrees, and is arranged at the two arc angles arranged at the external side of the hydrosphere; the thickness of the coating is 0. 1-0. 5 mm. The outer surface of the hydrosphere of the valve plate is added with the ceramic coating by the utility model, and the heat-proof fatigue performance of defending against the hot air action and the resistance to high temperature oxidation ability of the hydrosphere are reinforced; the durability of the hot air valve plate is enhanced.
Description
Technical field
The utility model relates to hot air valve plate.
Background technique
Existing hot air valve plate generally adopts cooling water to force cooling, utilizes to place metal hydrosphere and the valve seat of valve plate periphery to be sealed and matched, have high temperature resistant, the characteristics that anti-high pressure is out of shape.And in practical work process, because hot air valve plate is subjected to the hot blast effect strong, the hydrosphere surface erosion is serious, is starkly lower than the valve body of phase configuration working life, becomes the subject matter that hinders hot-blast valve raising in working life.
Summary of the invention
It is a kind of by strengthening the heat-resisting wind erosion performance of hydrosphere that the purpose of this utility model is to provide, and improves the hot-blast valve hot air valve plate in working life thereby reach.
The technological scheme that realizes above-mentioned purpose is: a kind of hot air valve plate that has hydrosphere, its outer surface at hydrosphere is provided with ceramic coating.
The utility model technological scheme more specifically is: ceramic coating is arranged in 120 ° of angular range of hydrosphere bottom; Its ceramic coating is arranged at the two arc angle places in the hydrosphere outside; The thickness of described ceramic coating is the 0.1-0.5 millimeter.
The utility model adds ceramic coating by the hydrosphere outer surface at valve plate, and the heat-resistant anti-fatigue performance and the oxidation-resistance property that make hydrosphere resist the hot blast effect strengthen greatly, thus the working life of having improved hot air valve plate effectively.
Description of drawings
Fig. 1 is this hot air valve plate plan view;
Fig. 2 is that hydrosphere outer surface ceramic coating is provided with structural representation;
Fig. 3 is the topology view that ceramic coating is arranged at two arc angle places, the hydrosphere outside.
Embodiment
In conjunction with the accompanying drawings embodiment of the present utility model is described.
Provide as accompanying drawing 1, accompanying drawing 2, this hot air valve plate has the hydrosphere 1 that places the valve plate periphery, is provided with ceramic coating 2 at the outer surface of hydrosphere.Its ceramic coating can whole evenly be arranged on the both sides sealing face and radial outer side of hydrosphere.Consider the nonuniformity that is subjected to the hot blast effect in the valve plate hydrosphere working procedure, its ceramic coating can be arranged on hydrosphere and be subjected in the 120 ° of angular range in the strong bottom of hot blast effect.The actual use of hot air valve plate shows, the valve plate hydrosphere is subjected to the outside two arc angle places of sensitive part in the 120 ° of angular range in hydrosphere bottom that hot blast effect thermal fatigue is damaged and high temperature oxidation damages, based on this, as shown in Figure 3, the utility model is considered the harmony of hydrosphere whole service life, and save cladding material to greatest extent, and reduce ceramic coating cost is set, ceramic coating 2 is arranged at the two arc angle places in the hydrosphere outside.
When the utility model was specifically implemented, ceramic coating adopted the multilayer spraying coating process, and coating thickness is the 0.1-0.5 millimeter.
Claims (4)
