Description
Technical field
The present invention relates to technical field of valve manufacturing.
Background technique
In the asphalt smoke purifying system of nonferrous metallurgy industry, when cause contains the easy adhesive gases such as bitumen flue gas by valve, meeting low temperature solidifies, cause butterfly plate and the valve body of valve to be sticked together, and cannot normally open or close, therefore in flue gas purification system, can cause following fault:
1. when the pitch seizure device in asphalt smoke purifying system detects spark, valve must first by throttle down, cut off air, then spray water and extinguish spark, if can not be closed in time, will cause fire, the secondary disasters such as intrasystem equipment is burnt are occurred;
In smelting process, by the open degree size of control valve, reach the effect that regulates 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 the chimney in cleaning system discharge and waste energy, bitumen flue gas that can not perfect combustion also can cause environmental pollution after discharging by chimney.
Summary of the invention
The object of the invention is for above problem, and a kind of bitumen flue gas special-purpose thermal insulation butterfly valve of avoiding bitumen solidification phenomenon is provided.
The present invention includes annular valve body, butterfly plate, described butterfly plate is arranged on annular valve body inner side, on described annular valve body, place a driving shaft, a driven shaft, described driving shaft and driven shaft coaxially arrange, and described butterfly plate is connected with the inner of driving shaft and driven shaft respectively, 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, angle level controller is set, on 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 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 drain pan internal surface, between upper end and top shell internal surface, be provided with gap, the upper end of described another piece baffle plate is fixed on described top shell internal surface, between lower end and drain pan internal surface, be provided with gap, between described each ring baffle, be respectively equipped with gap, and form serpentine passage, outer side wall at described annular valve body arranges respectively suction valve and gas outlet valve.
The present invention adopts mazy type valve body structure, when valve is connected after steam, the outer ring of valve body obtains homogeneous heating, can there is not curing phenomenon in the pitch of guaranteeing to stick on valve body and butterfly plate, and always in semi liquid state shape, butterfly plate and valve body can not be sticked together, when the pitch seizure device in 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 invention 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, while 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 insufficiently not discharged to such an extent that phenomenon occurs by chimney because burning, and the environment of periphery is under control.The present invention adopts Electrohydraulic push rod to drive valve opening and closing, have driving force large, operate steadily, highly sensitive, antioverloading ability is excellent and the advantage such as fragile long service life not, and on Electrohydraulic push rod of the present invention, increased a set of manual hydraulic device, even the in the situation that of power failure or other faults, also can pass through the switching of the timely control valve of manual hydraulic device.The present invention is rational in infrastructure, and safety in operation is high.
