Abstract
The invention discloses a valve rod with a positioning ring. According to the valve rod, a thread section (1) is arranged at the lower part of the valve rod; and the annular positioning ring (2) is arranged above the thread section (1). The valve rod with the positioning ring provided by the invention solves the problems of few processing procedures and waste of raw materials when the valve rod is positioned.
Description
Technical field
The present invention relates to valve rod, particularly a kind of valve rod with positioning ring.
Background technique
Valve rod is one of accessory of valve.The valve rod Main Function is for transmission, connects actuator or handwheel on the valve rod, below directly the band movable valve plug move or rotate, realize valve open or closed.Common valve rod location is by fixedly valve rod of a positioning ring is installed, exist manufacturing procedure many, waste problem of materials.
Summary of the invention
The objective of the invention is to solve valve rod when location exist manufacturing procedure many, waste problem of materials.
The technical solution used in the present invention is: a kind of valve rod with positioning ring, stem lower portion is provided with thread section, it is characterized in that the thread section top of described valve rod is fixed with the positioning ring of annular.
Described positioning ring and valve rod casting are connected as a single entity.
Described positioning ring and valve rod are welded as a whole.
Beneficial effect of the present invention is: the present invention has reduced manufacturing procedure by the circular orientation ring that is connected at valve rod, has improved manufacturing efficiency, has reduced material consumption, has reduced cost, has improved the performance of enterprises.
