Abstract

The invention discloses a sealing element structure and device of a two-phase flow fine measurement device under high temperature and high pressure, the sealing element structure comprises a sealing element body, the sealing element body is a cylinder, the sealing element body is axially provided with a through hole, and an electrode wire of the two-phase flow fine measurement device is arranged in the through hole; the sealing element body is arranged in a through structure on a substrate of the two-phase flow fine measurement device; the sealing element body is made of metal with a large thermal expansion coefficient, under the cold condition, the electrode wire penetrates through the through hole, the sealing element structure is assembled in the penetrating structure on the two-phase flow fine measurement device substrate, a first thermal expansion gap exists between the through hole and the electrode wire. A second thermal expansion gap is formed between the outer periphery of thesealing element structure and the inner periphery of the through structure on the substrate; when a high-temperature and high-pressure working condition experiment is carried out, the sealing elementbody generates thermal expansion along with temperature rise, the electrode wire and the through structure on the substrate are pressed, and sealing is achieved.

Description

technical field [0001] The present invention relates to the technical field of sealing structure of a two-phase flow fine measurement device, in particular to the seal structure and device of a two-phase flow fine measurement device under high temperature and high pressure, so that the fine measurement device can measure the two-phase flow under high temperature and high pressure conditions. The flow can be effectively measured, and it can meet the sealing requirements under high temperature and high pressure conditions. Background technique [0002] The limitation of the two-phase interface parameter measurement method is one of the key factors restricting the in-depth study of two-phase flow. The traditional probe measurement method can only achieve single-point measurement, and cannot obtain the instantaneous interface parameters of the entire cross-section of the flow channel. figure 1 The refined measurement device shown can realize the full-field instantaneous measurem...
