Combined flow dividing valve based on threaded transmission control

Abstract

The invention provides a combined flow dividing valve based on threaded transmission control and relates to the technical field of a valve. The flow dividing valve comprises a water inlet pipe, wherein a ball valve is slidably connected into the water inlet pipe, an upper side and a lower side of a right end of the water inlet pipe communicate with an upper water outlet pipe and a lower water outlet pipe correspondingly, a partition plate is fixedly mounted at communicating positions of the upper water outlet pipe, the lower water outlet pipe and the water inlet pipe, and a round hole is formed in the center of the partition plate. The flow dividing valve is advantaged in that abrasion caused by mutual attachment of a traditional valve element and a pipe wall is avoided, damage to the valve and the control effect due to the fact that a valve element is affected by thermal expansion and cold contraction is avoided, the service life of the valve is prolonged, practicability is improved,when foreign matter in the valve is cleaned or a plunger is replaced, the valve and a pipeline do not need to be disconnected, only the sealing plate needs to be directly opened, operation is simpler,and the time and labor are saved.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a combined diverter valve based on thread transmission control. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, adjust and control the parameters of the conveying medium. According to its function, it can be mainly divided into shut-off valve, check valve, regulating valve, etc., which are the control components in the fluid delivery system, with functions of cut-off, adjustment, flow diversion, reverse flow prevention, voltage stabilization, diversion or overflow pressure relief, etc. There are many varieties and specifications of valves used in fluid control systems, and diverter valves are one of them.

In order to achieve the cut-off...

AI Technical Summary

Problems solved by technology

[0003] The traditional diverter valve mainly realizes the cut-off and diversion of the fluid by rotating the spool at the connection between the main flow and the diversion. In order to achieve the cut-off effect of the spool, the spool must be in close contact with the pipe wall. During the process, the valve core will be worn, and after long-term use, it will affect the control effect of the valve core, and it is prone to leakage. The service life is not long, and the valve core will undergo cold and heat deformation, which will affect its sealing effect and make the valve shell The body expands and cracks, the temperature range that can adapt to the fluid is small, and the practicability is reduced, and the diversion valve will have different diversion pipes, and impurities are easy to accumulate at the connection between the diversion pipe and the main pipe and cause blockage. When dredging, the connection between the valve and the pipeline needs to be disconnected first, and then reconnected after the cleaning is completed. The operation is cumbersome and time-consuming
