Claims

[Scope of utility model registration request]

In a gate valve that is inserted into a pipe or duct and opens, closes, or regulates the flow of fluid, there is a perforated plate fixed on the upstream side of the flow and having holes in a staggered arrangement, and a perforated plate that is arranged upstream or downstream of the perforated plate, and A gate valve comprising a valve plate having a staggered arrangement having the same opening pitch as the above-mentioned perforated plate, the surfaces of which are in contact with each other, and a threaded rod and a handle are attached so as to be slidable.
