Abstract
The utility model relates to an oil machinery specifically is a take plunger type choke valve of cage nested structure, and it includes valve rod, plunger, valve gap, valve body, and the valve rod is connected with the plunger, and in the valve body was located to plunger and valve rod, the valve gap covered in the valve body opening part, characterized by: still include cage cover subassembly, cage cover subassembly is including the cover body and liner, in the valve body was located to the cover body, the plunger was located and is overlapped internally and at the internal reciprocating sliding of cover, overlap internal wall and inlayed liner in the gliding stroke section of plunger part. This choke valve has had the characteristics of plunger type and cage shell type choke valve concurrently, utilizes foraminiferous cage cover subassembly to change fluid flow and orientation to utilize the hydrodynamics principle to make fluid along the central line motion of cage cover, the inner chamber when having improved the throttle of traditional plunger type choke valve flows the condition, avoids decreasing and corroding dashing of throttling element, and reduces the motion noise.
Description
Technical field
