Abstract
The invention discloses a single-point needle valve. The single-point needle valve solves the problem that based on the prior art, a single-point needle valve processing size has already been determined and positioned and cannot be adjusted so that errors are produced easily and before operation is finished, the existing single-point needle valve is subjected to multiple mold modification or valve needle modification processes until the existing single-point needle valve data satisfies reasonable requirements. The single-point needle valve avoids multiple modification processes through utilization of a limit screw, realizes one-step adjustment of the cooperation of a valve needle and a mold to the optimal state, reduces mold and hot runner system modification time and optimizes product appearance quality.
