Lub valve no tso siab rau cov neeg kho tshuab torque es tsis yog cov dej siab kom ua tiav kev sib cais nruj. Thaum lub sij hawm kaw, lub disc mus ncig tsis tau lub rooj zaum kom txog rau thaum kawg ntawm ib tug degree. Applied actuator torque presses lub resilient disc foob nplhaib uniformly mus rau hauv lub conical lub rooj zaum, tsim elastic deformation uas tsim lub nqus tsev vacuum - nruj seal. Thaum qhib, lub disc tam sim ntawd tshem tawm ntawm lub rooj zaum lub nplhaib, tshem tawm kev hnav los ntawm cov nplaum los yog cov khoom siv polymerized nyob rau hauv lub tshuab nqus tsev.
