旋啟式止回閥

發布日期：2019-05-28 02:14:32

旋啟式止回閥的采用內裝搖臂旋啟式結構，閥門的所有啟閉件都裝于閥體內部，不穿透閥體，除了中法蘭部位用密封墊片和密封環外，整體沒有外漏點，杜絕閥門外泄的可能。旋啟式止回閥搖臂和閥瓣連接處采用球面連接的結構，使得閥瓣在360度范圍內有一定的自由度，有適當的微量位置補償。

適用于清凈介質，不宜用于含有固體顆粒和粘度較大的介質。

Product Details

The swing-type check valve adopts the built-in rocker arm swinging structure. All the opening and closing parts of the valve are installed inside the valve body, and do not penetrate the valve body, except for the sealing gasket and the sealing ring of the middle flange part, the whole There is no leakage point to prevent the possibility of valve leakage. The swing-type check valve has a spherical connection structure at the joint of the rocker arm and the valve flap, so that the valve flap has a certain degree of freedom within a range of 360 degrees, and has appropriate micro-position compensation.

Suitable for clean media, not suitable for media containing solid particles and high viscosity
