Abstract
The invention discloses a gate valve with an intermediate sealing structure, which comprises a valve body and a valve cover, wherein the valve cover is detachably connected with the valve body, a valve core is arranged at the center of the valve body, an annular sealing ring groove is arranged at the top of the valve body, and a detachable sealing ring is arranged in the sealing ring groove. Because the sealing ring is arranged at the joint, the sealing property of the connection between the valve body and the valve cover is greatly improved. The gate valve with the middle sealing structure is simple in structure, obvious in effect, low in cost and high in practicability.
Description
