摘要：Gas-liquid two-phase current systems are widely existed in the petroleum, the chemical industry, the metallurgy, the nuclear power and many industrial fields. Two-phase's phase distribution and measurement can't be avoided in two phase current system. And it is also a difficult problem that has not been solved. In this paper, we designed a pitot-distributor. Experimental measurement and theory analysis were carried out to study the distribution data and situation of the distributor in gas-liquid two-phase flow. Firstly, a special experimental device for pitot-distributor was designed and experiments were carried out at air-water two-phase flow loop. The main text pipeline's diameter is 50mm, the system pressure is 0.24~0.28MPa, there are five branches in the pitot-distributor, each branch's diameter is 8mm. The paper has first analyzed the influencing factors of gas extraction ratios and liquid extraction ratios, which were effected by four different types of pitot-separator. Next, it analyzed different efforts under two kind of pressure. Then, we established the math model and calculated the coefficients. Last, we analyzed the erroneous. The experimental result indicated that the tube-12345 structure is the perfect one which can keep extraction ratios more stable in a quite wide rang. Liquid extraction ratios (KL) mainly are affecting by the pressure and its structure. The gas extraction ratios (KG) mainly are affecting by the pressure.
