If necessary to be closed cast gate 3131, then liquid is controlled by electromagnetic valve component 331 and flowed out from first interface 332, flowed later
Body is flowed into from epicoele entrance 31411 and is flowed out by cavity of resorption entrance 31421, then is flowed into from second interface 333, at this point, in hot flow path
In system 31, the flow direction of liquid is the first flow direction, and therefore, cast gate 3131 is in eventually closed state, it is possible to understand that
It is in the process, adjusting need not to be made to flow rate regulating valve 334, or flow rate regulating valve 334 is made to be in maximum flow rate
State；(2) in use, if necessary to open cast gate 3131, firstly, it is necessary to by the flow velocity of flow rate regulating valve 334
Adjust to a desired value, then by electromagnetic valve component 331 control liquid from second interface 333 flow out, later liquid from
Cavity of resorption entrance 31421 is flowed into and is flowed out by epicoele entrance 31411, is flowed into from first interface 332, at this point, in hot runner system
In 31, the flow direction of liquid is the second flow direction, and therefore, cast gate needle 3132 moves upwards and eventually disengage from cast gate 3131,
Therefore, in the process, the flow velocity for continuing to adjust flow rate regulating valve 334 is needed, for example, at the beginning, the desired value is adjusted
To a minimum value, then slowly increase the flow velocity (can at the uniform velocity increase) of flow rate regulating valve 334, so as to control cast gate valve
The speed that needle 3132 moves upwards, i.e., at the beginning so that sizing material 11 is flowed out from cast gate 3131 with the flow velocity of very little, and flow velocity is slow later
Slow to increase, therefore, sizing material has unified flow front flow velocity and pressure, to avoid final product have defect (such as：
Heat spot or weld mark etc.).
Here, flow rate regulating valve 334 can with various types of valves, such as：Throttle valve, one-way throttle valve etc..And it should
Flow rate regulating valve 334 can be to be adjusted manually (for example, be provided with speed governing knob in the flow rate regulating valve 334, for can
To rotate speed governing knob, and then adjust the flow velocity that liquid flows through flow rate regulating valve 334), or electronically controlled (example
Such as, which receives when including the regulating command of flow speed value, can adjust liquid with the flow speed value and flow through
The flow velocity of fast regulating valve 334).
Optionally, reversal valve 3313 can be electronically controlled, and regulating command is flowed to when reversal valve 3313 receives first
When, control liquid is flowed into from first interface 332 and is flowed out from second interface 333；When reversal valve 3313 receives the second flow direction
When regulating command, control liquid is flowed into from second interface 333 and is flowed out from first interface 332.

Flow velocity when one interface 332 is flowed into, flowed out by fluid channel, again from second interface 333, but do not control liquid and connect from second
Flow velocity when mouth 333 is flowed into, flowed out by fluid channel, again from first interface 332.Fig. 4 shows one kind of one-way throttle valve
Principle schematic, the i.e. one-way throttle valve are that check valve and throttle valve are formed in parallel.
Preferably, the one-way throttle valve includes check valve and throttle valve；When liquid from first interface 332 flow into,
When being flowed out by fluid channel, again from second interface 333, liquid can only be flowed through from throttle valve and can not be flowed through from check valve；
When liquid is flowed into, flowed out by fluid channel, again from first interface 332 from second interface 333, liquid can be from unidirectional
Valve flows through.
In Fig. 4, when liquid flows to B from A, check valve blocks, and liquid can only be flowed through from throttle valve, therefore,
Throttle valve can adjust the flow velocity of liquid；And when liquid flows to A from B, then liquid can be flowed through from check valve, because
This, throttle valve can not just adjust the flow velocity of liquid.
Preferably, the liquid is gas or oil body.
Preferably, as shown in figure 3, the first interface 332 and second interface 333 are connected to the oil pressure electricity by pipeline
