However, in practical application, the sampler of the type has the problems that the temperature of high-temperature oil products cannot be controlled and the oil products in the sampler cannot be swept clean after sampling is finished, and has great potential safety hazards; if the circulating water quantity is too small, the temperature of the high-temperature heavy oil is too high, and the effluent oil product is contacted with air, so that spontaneous combustion is easy to occur to cause accidents; in addition, when sampling is finished and the sampling flow channel is purged by steam, the sampling oil product is low in temperature and high in viscosity and is attached to the sampling flow channel, so that the accuracy of next sampling is seriously influenced.
