Abstract
The utility model discloses a valve rod of a flanged joint soft sealed fixing ball valve. The valve rod comprises a valve rod body and is characterized in that a plurality of annular grease storage grooves are formed in the side wall at the upper end of the valve rod; a bulged shoulder is arranged at the lower end of the valve rod; a spring hole is formed in the side wall of the bulged shoulder; a spring is arranged in the spring hole; a steel ball is arranged at the upper end of the spring and can slide along the spring hole to be matched with a limiting hole in the side wall of the valve body so as to limit the valve rod timely. The valve rod is simple in structure and good in leakproofness and can timely remind an operator of the closing degree of a valve.
Description
Technical field
The utility model relates to a kind of flange and connects soft sealing type fixing ball valve valve rod.
Background technique
In prior art, the unreasonable structure of valve rod can cause valve leak, and valve is in the process of closing, owing to overexerting, can cause valve by locked, the situation of not opening, when in traditional technology, lack prompting accurately, valve such prompting structure that forwarded position to.
Model utility content
The utility model object is to provide a kind of simple in structure, and good airproof performance can remind the flange of the degree of closing of operator's valve to connect soft sealing type fixing ball valve valve rod in time.
The utility model technical solution problem provides following scheme:
A kind of flange connects soft sealing type fixing ball valve valve rod, comprise valve-rod body, it is characterized in that: described valve rod upper end sidewall is provided with a plurality of annular grease storage grooves, the lower end of described valve rod is provided with convex shoulder, and the sidewall of described convex shoulder is provided with spring eye, in described spring eye, is provided with spring, the upper end of described spring is provided with steel ball, described steel ball can slide along spring eye, and proportioning valve body sidewall upper limit hole can be carried out spacing to valve rod in time.
The upper end of described valve rod is provided with spanner seat.
The utility model is provided with the grease storage groove of a plurality of annulars on the sidewall of valve rod upper end, so conveniently from valve housing, valve rod is carried out to greasing operation, sealing is improved, and the lower end at valve rod is provided with convex shoulder, on the sidewall of convex shoulder, is provided with spring eye, and is provided with steel ball in spring eye, proportioning valve body sidewall upper limit hole, can to valve rod, carry out in time spacingly, preventing from overexerting causes the seal ring of valve to be damaged by pressure, and the locked valve that causes is difficult to again open.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
