The asphalt circulation combined control valve applied to the asphalt spraying vehicle comprises a valve body, a valve body cavity and a liquid inlet are formed in the valve body, a circulation mechanism is arranged on the valve body, and a spraying mechanism is arranged on the valve body. The liquid inlet is communicated with the asphalt tank, and asphalt in the asphalt tank enters the valve bodycavity through the liquid inlet by means of a conveying pump. By adopting the structure, when the spraying mechanism is closed and the circulation mechanism is opened, asphalt in the asphalt tank circularly flows between the asphalt tank and the valve body; when the circulation mechanism is closed and the spraying mechanism is opened, asphalt does not flow back to the asphalt tank of the asphaltspraying vehicle any more and flows into the spraying pipeline completely, and at the moment, the spraying head is opened, so that asphalt spraying can be realized. By the adoption of the structure, in the transportation process, asphalt in the asphalt tank of the asphalt spraying vehicle is in a circulation flowing state, the asphalt stirring effect is achieved, and the situation that the asphaltis frozen and layered in the transportation process is effectively prevented.
本发明公开了应用在沥青喷洒车上的沥青循环组合控制阀，包括阀体，阀体上设有阀体腔和进液口，阀体上设有循环机构，阀体上喷洒机构。进液口与沥青罐连通，沥青罐中的沥青通过输送泵使沥青通过进液口进入阀体腔。采用这种结构，当闭合喷洒机构，开启循环机构时，沥青罐内的沥青将在沥青罐与阀体间循环流动；当闭合循环机构，开启喷洒机构时，沥青将不再回流至沥青喷洒车的沥青罐，将全部流至喷洒管路内，此时，打开喷头，即可实现沥青的喷洒。采用这种结构，在运输的过程中，沥青喷洒车的沥青罐内的沥青处于循环流动状态，即起到了对沥青的搅拌作用，又有效防止沥青在运输过程中出现冻结、分层的情况。
