【簡單介紹】
截止閥屬于強制密封式閥門,所以在閥門關閉時,必須向閥瓣施加壓力,以強制密封面不泄漏。當介質由閥瓣下方進入閥六時,操作力所需要克服的阻力,是閥桿和填料的摩擦力與由介質的壓力所產生的推力,關閥門的力比開閥門的力大。

型號: | J41W | 口徑: | DN15-DN600 |
壓力: | 1.6MPA-4.0MPA | 材質: |
正光閥門集團截止閥(Globe Valve)的啟閉件是塞形的閥瓣,密封面呈平面或錐面,閥瓣沿流體的中心線作直線運動。閥桿的運動形式,有升降桿式(閥桿升降,手輪不升降),也有升降旋轉桿式(手輪與閥桿一起旋轉升降,螺母設在閥體上)。截止閥只適用于全開和全關,不允許作調節(jié)和節(jié)流。
