The utility model discloses a cigarette wind channel high temperature seal butterfly valve, valve plate can rotate around the valve plate axle and with the sealed cooperation of seal receptacle line, because the seal receptacle is by having rigidity, pliability, heat resistance, corrosion resistance, the seal receptacle structural strength is not fragile more, its sealed effect with the valve plate is better.
Description
Technical Field
The utility model relates to a sealed butterfly valve field, concretely relates to flue high temperature seal butterfly valve.
Background
The flue gas duct high-temperature sealing butterfly valve is widely applied to flue gas duct systems of various heating furnaces, and has the main function of preventing flue gas and air from being connected in series, so that the utilization rate of the heating furnace on the heat of the flue gas is improved, and the heat efficiency of the heating furnace is improved. Because the high-temperature working environment of the smoke and air duct butterfly valve is very harsh, the valve plate of the butterfly valve is flexibly rotated, and is not jammed and deformed. The existing design and manufacturing specifications generally allow a certain leakage amount of the butterfly valve, and a gap is reserved between a sealing valve seat and a valve plate of the butterfly valve, so that the existing commonly-used butterfly valve has poor sealing effect due to the existence of the gaps.
Based on the above problems, a high-temperature sealing butterfly valve with a flexibly rotatable valve plate and a good sealing effect needs to be designed.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the scheme provides a flue high-temperature sealing butterfly valve to improve the sealing effect of a flue system, and further improve the heat utilization rate of a heating furnace.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a flue air duct high temperature seal butterfly valve, includes disk seat, butterfly valve plate and valve plate axle, be used for on the disk seat to be provided with the seal receptacle with the sealed one end of butterfly valve plate, the seal receptacle is with the sealed cooperation of a corresponding end line of butterfly valve plate, the seal receptacle is made by the material that has rigidity, pliability, heat resistance, corrosion resistance.
Further, the seal seat is made of steel.
Further, the seal receptacle is fixed set up in on the disk seat, the one end that is used for with the sealed complex of butterfly valve plate of seal receptacle is the overhang end.
Further, the overhanging end is provided with a sealing matching inclined plane which is obliquely arranged relative to the butterfly valve plate, and the sealing matching inclined plane is in line sealing matching with the butterfly valve plate.
Further, the seal seat is fixed on the valve seat through a bolt.
The utility model discloses a cigarette wind channel high temperature seal butterfly valve, valve plate can rotate around the valve plate axle and with the sealed cooperation of seal receptacle line, because the seal receptacle is by having rigidity, pliability, heat resistance, corrosion resistance, the seal receptacle structural strength is not fragile more, its sealed effect with the valve plate is better.
Drawings
Fig. 1 is a schematic view of a partial structure of embodiment 1 of the high-temperature sealing butterfly valve for a flue gas duct of the present invention.
In the figure: 1. a valve seat; 2. a sealing seat; 21. a cantilevered end; 22. sealing the matched inclined plane; 3. butterfly valve plate.
Detailed Description
The following describes the high-temperature sealing butterfly valve of the flue duct in detail with reference to the attached drawings.
The utility model discloses a flue gas wind channel high temperature seal butterfly valve's embodiment 1 is as shown in figure 1, including disk seat 1, butterfly valve plate 3 and valve plate axle (not shown in the figure), butterfly valve plate 3 can rotate around the valve plate axle. Be used for being provided with seal receptacle 2 with 3 sealed one ends of butterfly valve plate on the disk seat 1, seal receptacle 2 passes through the bolt fastening on disk seat 1. The one end that is used for with the sealed complex of butterfly valve plate 3 of seal receptacle 2 is overhang end 21, and overhang end 21 is provided with sealed cooperation inclined plane 22 for the slope setting of butterfly valve plate 3, sealed cooperation inclined plane 22 and 3 line seal cooperations of butterfly valve plate. The sealing seat 2 is made of a material having rigidity, flexibility, heat resistance, and corrosion resistance, and specifically, the sealing seat 2 is made of a thin steel plate having a thickness of 2mm in the present embodiment.
The utility model discloses a cigarette wind channel high temperature seal butterfly valve, drive butterfly valve plate 3 through rotating the valve plate axle and rotate the top and press on seal receptacle 2 and with 2 line seal cooperation of seal receptacle, because seal receptacle 2 is by having the rigidity, the pliability, the heat resistance, corrosion resistance's steel is made, 2 structural strength of seal receptacle are not fragile greatly, and the roof pressure of seal receptacle 2 and butterfly valve plate 3 is inseparabler, it is better with butterfly valve plate 3's sealed effect, thereby the sealed effect of cigarette wind channel system has been improved, the heat utilization ratio of heating furnace has been improved.
In other embodiments, the sealing seat may be fixed to the valve seat by welding or riveting or other conventional fixing connection means.
In other embodiments, the sealing matching inclined surface of the overhanging end can be replaced by a sealing matching curved surface as long as the linear sealing matching with the valve plate of the butterfly valve can be realized.
Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of this invention as claimed.
