Lateral openings, corresponding side wall one is symmetrically formed with two axial grooves to both sides extension in the middle part of bar-shaped trough, upper opening, one laterally open
An embedded space is collectively formed in mouth and two axial grooves, for being embedded in valve stem end T forming heads；In rectangular connecting portion upper end, open
The top of mouth both sides is integrally formed with reinforcement block, and sliding slot is radially formed on the corresponding valve plate in lateral openings side of rectangular connecting portion,
Sliding slot extends into the opening of rectangular connecting portion, until at the opening sidewalls of rectangular connecting portion, in the upper opening of rectangular connecting portion
Go out and a caulking groove is radially formed on corresponding valve plate body, a spring is embedded in caulking groove；The lower end outer rim mirror image pair of the valve rod
Title is formed with two radial grooves, and the valve rod of groove lower part is T forming heads, circular groove card slot is formed in valve rod lower end, in circular groove card slot
It is embedded in spring.
Moreover, it is formed with the downward arc convex of arc at the top of the groove body of two axial grooves in the opening of rectangular connecting portion.
The beneficial effects of the utility model are：
A cunning chamber is formed on the gate valve plate of install convenient provided by the utility model, can by the larger valve rod in head from
Sliding chamber slides into the connecting portion of valve plate, and installation is very convenient, easy to connect, and conversion is quick, improves the production efficiency of valve.
The quick secured connection structure of the gate valve plate of install convenient provided by the utility model, in the corresponding valve of connecting portion
System is embedded in a spring, after valve rod is embedded in, spring can jack up valve rod, can ensure there are one caulking groove on body in caulking groove
Valve rod is not skidded off out of connecting portion, prevents the valve rod in installation and practical process from being slid out of sliding slot, colleague also eliminates four directions
This component of nut, reduces manufacturing procedure, reduces production cost.
