For core upper and lower ends integrally formed with shaft, the valve body is interior to be equipped with connection turn at the top of butterfly valve core and shaft by shaft
Xiang Zhu, on the right side of the butterfly valve core in check valve spool is installed.
Preferred: the novel controllable check valve further includes arc groove, shaft groove and spring leaf, the butterfly valve valve
Core right side opening is equipped with arc groove, and the arc groove upper and lower ends offer shaft groove, and the check valve spool passes through
Shaft is mounted in arc groove and can rotate around shaft groove, and being equipped with spring leaf on the left of the check valve spool can realize
Even if Hui Zhengfang backflow when fluid countercurrent current in valve.
It is preferred: the valve body, marking nameplate, connection sheet, screw, cross fixing seat, steering column, bolt, handle,
Shaft, butterfly valve core, check valve spool and spring leaf are all made of the production of 304 stainless steel materials.
The beneficial effects of the utility model are: the utility model structure is simple, design rationally, can not only realize that standard is stopped
Valve function is returned, butterfly valve unlatching can also be manually controlled by handle if necessary and realize that fluid countercurrent current can also pass through replacement in valve
The pipeline of the connection sheet connection different tube diameters of different size.
