Part processed）, according to preferred embodiment, referring to the use state of the electronic temperature control control valve device shown in Figure of description 1-5,
First the mechanical part of electronic temperature control control valve device is explained.
For electronic temperature control valve, it necessarily includes valve body 8, and valve body 8 is generally equipped with valve pocket, then matching valve cavity configuration,
Valve opening is provided with valve body wall, because valve opening typically wants pipe arrangement, thus the also commonly referred to as fluid mouth of pipe or interface.
Valve pocket is generally not simple cylinder inner chamber, it is necessary to according to specific flow passage structure, design such as valve opening groove and
Spool land, the wall valve opening hole in the space that wherein valve opening groove is formed.Concrete structure on valve body belongs to this area
Conventional structure, will not be repeated here.
The realization of valve function is necessarily dependent upon valve element 33, and this is also to combine control section as the progress of electronic temperature control valve is whole
The reason for body illustrates, clearer it can be appreciated and understood by by those skilled in the art.
