Seal, the bottom of the runner fluid chamber are equipped with nozzle positioning column, and the nozzle is installed on institute by the nozzle retaining cap
State the bottom of nozzle positioning column.
Further, the bottom of the flow path bodies is a ramped bottom surface, and the ramped bottom surface is close to the runner plug
One end be higher than close to the nozzle retaining cap one end.
Further, a channel is offered at the top of the flow path bodies, the channel is connected to the runner fluid chamber,
The sealing ring is removably embedded at the channel close to one end of the runner fluid chamber, the size of the sealing ring and institute
The size for stating channel matches.
Further, the runner plug is used with the flow path bodies and is threadedly coupled.
Further, the female Luer is used with the flow path bodies and is threadedly coupled.
Further, the nozzle retaining cap is locked the nozzle by being threadedly coupled with the nozzle positioning column.
Compared with prior art, beneficial effect is the utility model: the liquid flow for injection valve of the utility model
Road component, runner are obliquely installed, and reduce lateral occupied space, and female Luer is installed at the top of flow path bodies and stifled close to runner
Head, the components such as nozzle retaining cap, nozzle are located at the one end of runner far from runner plug, so that entire flow channel for liquids component is in I shape,
It is compact-sized, it occupies little space when installing and using.Fluent material enters runner by female Luer, subsequently into runner liquid
Chamber, runner plug block one end of runner, and the top of runner fluid chamber is equipped with sealing ring, thus entire liquid flow space shape
At the environment of a tight closure, effectively prevent fluent material from leaking.
Detailed description of the invention
Fig. 1 is a kind of longitudinal schematic cross-sectional view of the flow channel for liquids component of injection valve provided by the embodiment of the utility model.
