Description

Injection valve

Technical Field

The utility model relates to an injection valve, in particular to an injection valve in a metering pump or a dosing system.

Background

The dosing metering pump is a special volumetric pump which can meet the requirements of various strict process flows, can realize stepless regulation of the flow rate within the range of 0-100 percent and is used for conveying liquid (such as adding disinfectant to drinking water). Metering or dosing systems inject small amounts of fluid into the forward flow of chemical. The injection valve is a component in this metering pump system for injecting small amounts of chemicals into the flow conduit. Ideally, the injection valve is inserted to a depth that is centered in the flow stream and injects the injected liquid evenly into the flow stream.

In the prior art, the injection valve is directly connected with a pipeline, if a large-diameter pipeline is met, the liquid medicine is difficult to be uniformly mixed with the liquid in the pipeline, and the technical problem of large difference of the concentration of the liquid medicine in the pipeline is easily caused.
