AI Technical Summary
Technical Problem
The stem of existing throttle valves is prone to loosening due to vibration under high pressure, which can cause the valve core to move upward and leak, affecting the performance of the valve.
Method used
The valve stem structure consists of an upper stem and a lower stem. Through the threaded connection between the screw and the sliding sleeve and the limit groove design, combined with the multiple sealing structure of the sealing ring and sealing ring, the valve stem is prevented from loosening and leakage.
Benefits of technology
It effectively prevents the valve stem from loosening during vibration, avoids leakage caused by the valve core moving upward, and improves the sealing performance and reliability of the throttle valve.

Abstract
The utility model provides a novel throttle valve belongs to valve body technical field, including valve subassembly and anti loosening structure, valve subassembly is by valve body, installation cover, valve rod and valve core is composed, the utility model: valve rod is by upper stem body and lower stem body two parts constitute, is connected with screw rod in the upper stem body bottom, lower stem body top installs the sliding sleeve, and screw rod is connected in the thread groove of sliding sleeve inside opening in the thread, and the inside of installation cover is installed with the guide sleeve, and the inner wall of guide sleeve opens the limit slot, and sliding sleeve slides in the limit slot through both sides' limit sliding block, when the upper stem body rotates, drives screw rod to rotate in the sliding sleeve, and sliding sleeve is lifted and removed along screw rod under the limit of limit slot, thereby makes the drive valve core lift and open and close, because the upper stem body and lower stem body are connected through screw rod sliding sleeve, make valve rod not to produce loosening when being vibrated, avoid the leakage caused by the valve core upward movement.
