摘要： A substantially leak-free, sealable microvalve that can be repeatedly opened and sealed is presented. The resealable microvalve includes a block with a through via and a sealing plate. The gap between the block and the sealing plate is sealed by a sealing material. The sealing material can be melted when heat is applied and can be solidified when heat is absent. To close the resealable microvalve, heat is applied by flowing a current through a resistive heater and an actuator brings the block and the sealing plate into a contacting position. By removing the heat, the sealing material is solidified and creates a sealed state. To open the resealable microvalve, heat is applied to the sealing material. When the sealing material melts, the actuator moves the block and the sealing plate into a spaced apart position.
摘要翻译：提出了可重复打开和密封的基本无泄漏，可密封的微型阀。可重新密封的微型阀包括具有通孔和密封板的块体。块体与密封板之间的间隙由密封材料密封。当加热时密封材料可以熔化，并且当不存在热时可以固化。为了关闭可重新密封的微型阀，通过使电流流过电阻加热器来施加热量，并且致动器使块和密封板进入接触位置。通过去除热量，密封材料固化并产生密封状态。为了打开可重新密封的微型阀，将热量施加到密封材料上。当密封材料熔化时，致动器将块和密封板移动到间隔开的位置。
