Volume control type sewage pipe connecting valve

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of drainage valves, in particular to a volume-controlling sewage pipe connection valve. Background technique [0002] Drainage pipes refer to the system composed of pipes and channels for collecting and discharging sewage, waste water and rainwater and their ancillary facilities, including main pipes, branch pipes and pipes leading to treatment plants. Due to the limitation of the rated length of the drainage pipeline, when the drainage pipeline is actually buried, the pipeline needs to be grafted, and the pipeline is sealed and connected through the flange. In the diversion and confluence section of the drainage pipeline, a valve needs to be connected to connect the pipeline. It is used to control the flow direction and flow of sewage in the pipeline. [0003] At present, the control valves mainly include stop valves, plug valves, butterfly valves, ball valves, etc., which are used for throttling control, ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a volume control type sewage pipeline connection valve, which has the advantages of high precision of manual adjustment, anti-clogging, easy cleaning and maintenance, and low centering accuracy requirements at the valve body connection, which solves the problem of The control accuracy of the traditional ball valve is not high, and the control accuracy for the confluence and diversion of sewage is insufficient. At the same time, because the sewage contains various impurity particles, it is easy to cause blockage to the ball valve, and the inconvenience of maintenance and disassembly will easily lead to an increase in maintenance time.
