GATE VALVE WITH REPLACEABLE INSERTS AND METHOD OF REFURBISHING SAME |
摘要 |
A gate valve includes a valve body having a cylindrical passage defining a flow path through the valve, a gate for controlling fluid flow through the valve and a replaceable wear-resistant flow-path liner for in the flow path. The flow-path liner includes a plurality of replaceable wear-resistant inserts, including wear sleeves lining ports of the valve body, valve seats and a gate insert for a flow path bore through the gate. Each replaceable valve seat has a wiper ring for cleaning the gate when it opens and closes. By regularly inspecting and replacing worn-out inserts, the service life of the gate valve can be prolonged and the expense associated with replacing or rebuilding the valve body is avoided.
