Description
Technical field
The utility model relates to technical field of valve manufacturing.
Background technique
In the asphalt smoke purifying system of nonferrous metallurgy industry, meet low temperature when easily adhesive gas is by valve and solidify because containing bitumen flue gas etc., cause butterfly plate and the valve body of valve to be sticked together, and can't normally open or close, therefore in flue gas purification system, can cause following fault:
1. when the pitch seizure device in the asphalt smoke purifying system detects spark, valve must cut off air by throttle down first, spray water and extinguish spark, if can not in time be closed, will cause fire, the secondary disasters such as intrasystem equipment is burnt are occured;
In smelting process, open degree size by control valve, reach the effect of regulating pipe negative pressure, if can not normally adjust, rock gas and pitch can not fully be burnt, cause a large amount of rock gases directly to be discharged by the chimney in the cleaning system and waste energy, after bitumen flue gas that can not perfect combustion is discharged by chimney, also can cause environmental pollution.
Summary of the invention
The utility model purpose is for above problem, and a kind of bitumen flue gas special-purpose thermal insulation butterfly valve of avoiding the bitumen solidification phenomenon is provided.
The utility model comprises annular valve body, butterfly plate, and described butterfly plate is arranged on the annular valve body inboard; Place a driving shaft, a driven shaft at described annular valve body, the coaxial setting of described driving shaft and driven shaft, described butterfly plate is connected the inner with driving shaft respectively and is connected with driven shaft; The outer end of described driving shaft is connected with the telescopic end of Electrohydraulic push rod by connecting rod, and described Electrohydraulic push rod is connected with valve body by bearing; In the outer end of described driven shaft the angle level controller is set; At described bearing manual hydraulic device is set; Described annular valve body is hollow structure, described annular valve body comprises top shell, drain pan, inner chamber at described annular valve body arranges the mazy type heat preservation mechanism, described mazy type heat preservation mechanism comprises the some ring baffles with the concentric setting of annular valve body, described every two adjacent equal interlaced arrangement of ring baffle, the described wherein lower end of a baffle plate is fixed on the drain pan internal surface, be provided with the gap between upper end and the top shell internal surface, the upper end of described another piece baffle plate is fixed on the described top shell internal surface, be provided with the gap between lower end and the drain pan internal surface, be respectively equipped with the gap between described each ring baffle, and consist of the serpentine passage; Outer side wall at described annular valve body arranges respectively suction valve and gas outlet valve.
The utility model adopts the mazy type valve body structure, after valve is connected steam, the outer ring of valve body obtains homogeneous heating, guarantee to stick to the phenomenon that the pitch on valve body and the butterfly plate can not solidify, and being in the semi liquid state shape always, butterfly plate and valve body can not be sticked together, when the pitch seizure device in the asphalt smoke purifying system detects spark, guarantee that valve can normally open or close, avoid disaster to occur.Driven shaft free end of the present utility model has been installed angular displacement sensor, after control box with valve matched is connected, can be long-range or the open degree size of on-the-spot any control valve, when guaranteeing that valve is used to control the flow of the gases such as bitumen flue gas, reach the effect of any adjusting pipe negative pressure, rock gas and pitch can fully be burnt, save a large amount of rock gases, bitumen flue gas that can not perfect combustion can be because insufficient the discharge by chimney of burning not get phenomenon and occurs, and the environment of periphery is under control.The utility model adopts Electrohydraulic push rod to drive valve opening and closing, have driving force large, operate steadily, highly sensitive, the antioverloading ability is excellent and the advantage such as fragile long service life not, and increased by a cover manual hydraulic device on the utility model Electrohydraulic push rod, even in the situation that have a power failure or other faults, also can be by the switching of the timely control valve of manual hydraulic device.The utility model is rational in infrastructure, and safety in operation is high.
