For achieving the above object, the technical solution adopted in the utility model is: a kind of pipeline butterfly valve, comprise by center and all there is the left valve barrel portion of passage, valve body, flap and the handle that right valve barrel portion forms, be positioned at described left valve barrel portion, right valve barrel portion end flange end face is separately equipped with semi-spherical grooves, described flap is positioned at by left valve barrel portion, the right valve barrel portion space that semi-spherical grooves forms separately;
The one valve rod lower end that is positioned at valve jacket is connected with described flap, described valve jacket upper-end surface is fixed with a lock collar, this lock collar circumferentially offers some positioning grooves, one handle is installed on the valve rod upper end that is positioned at lock collar top, the middle part of one depression bar is flexibly connected by rotatingshaft with described handle middle part, and one end of this depression bar embeds in the positioning groove of described lock collar;
One spring bolt with through hole is fixed on described handle side surface, this spring bolt embeds the circular hole of depression bar and exposes described through hole, one U-lock bar cramp is held described depression bar and handle and its one end and is embedded in the through hole of described spring bolt, and the lower end of this U-lock bar is installed on a tapered end.
In technique scheme, further improvement project is as follows:
In such scheme, a spring fitting is in described depression bar and handle separately between end.
Because technique scheme is used, the utility model compared with prior art has following advantages and effect:
The utility model pipeline butterfly valve, its handle is installed on the valve rod upper end that is positioned at lock collar top, the middle part of one depression bar is flexibly connected by rotatingshaft with handle middle part, one spring bolt with through hole is fixed on described handle side surface, this spring bolt embeds the circular hole of depression bar and exposes described through hole, one U-lock bar cramp is held described depression bar and handle and its one end and is embedded in the through hole of described spring bolt, the lower end of this U-lock bar is installed on a tapered end, at ball valve when opening completely or closing, can guarantee the in the situation that of non-artificial unblanking, can not produce the improper keying that rotatable handle causes valve because of other factors, secondly, it increases working life, simple in structure, and the danger operating has fallen in operating mode for ball valve in HEATING BOX greatly, and operation and installation are simple and easy convenient.
