本實(shí)用新型提供的是帶有格萊圈雙密封圈平衡結(jié)構(gòu)的電動(dòng)調(diào)節(jié)閥門。閥芯組件由閥桿、閥芯、閥塞、密封墊、格萊圈、螺母、防松墊圈組成，閥塞上帶有格萊圈，閥芯與閥桿通過螺紋連接，閥塞與閥芯中間夾有密封墊，用防松墊圈和螺母將閥塞擰緊在閥桿上，此時(shí)密封墊被閥塞與閥芯夾緊，固定在其中間。將閥座擰緊在閥體上，再將組裝好的閥芯組件裝入閥體內(nèi)，依次將石墨復(fù)合墊片、氣缸、石墨復(fù)合墊片裝入閥體，zui后裝入底蓋，并用螺栓將其擰緊固定。zui后將填料壓蓋裝入閥體并擰緊。本實(shí)用新型工作平穩(wěn)。靜態(tài)摩擦系數(shù)小，能量損失少且生熱低；磨性好、耐老化、壽命長(zhǎng)。適宜作為電動(dòng)調(diào)節(jié)閥使用。
