The invention relates to the technical field of drainage valves, and discloses a
volume control type
sewage pipe connecting valve. The
volume control type
sewage pipe connecting valve comprises a pipebody.
Flange plates are fixedly connected to the left and right ends of the
pipe body, a
ball valve body is fixedly installed on the middle portion of an inner cavity of the pipe body, sealing fasteners are fixedly installed at the junction between the upper and lower outer walls of the
ball valve body and the inner wall of the pipe body, the bottom end of the
ball valve body is fixedly connectedwith the inner wall of a
valve seat bearing in a sleeving mode, the bottom end of the
valve seat bearing is fixedly connected with the inner bottom of the pipe body, the top end of the ball valve body is fixedly connected with an upper
valve stem, and a valve top bearing is fixedly connected to the outer wall of the upper
valve stem in a sleeving mode. According to the
volume control type sewagepipe connecting valve, by arranging a gear set, a
handle rotates two circles to drive a first
bevel gear to rotate one circle, so that a driven gear drives a driving gear to rotate by ninety degrees,that is, the
handle rotates two circles to drive the ball valve body to rotate an opening and closing period, so that higher rotation precision is conveniently obtained under the condition of manual rotation, and the control amount of the equipment to the pipeline
water flow is more accurately controlled.
