Description of the drawings
By as shown in the accompanying drawings for the preferred but non-row by gas-pressurized supplied to the feeding mechanism of tire
The embodiment of his property illustrative and thus be non-limiting description, will more clearly learn that the present invention's is further
Feature and advantage, wherein：
- Fig. 1 shows the pneumatic schematic diagram of the feeding mechanism of gas-pressurized according to prior art；
Fig. 2 shows the sectional views of the feeding mechanism of the gas-pressurized in Fig. 1；
- Fig. 3 shows the pneumatic schematic diagram of the feeding mechanism of gas-pressurized according to the present invention；
- Fig. 4 shows the sectional view of the feeding mechanism of the gas-pressurized in Fig. 3.
Specific implementation mode
Refer to the attached drawing, label 1 indicate the feeding mechanism for gas-pressurized to be supplied to tire 100.
Feeding mechanism 1 includes：
It can be connected to the entrance 2 of pressurized-gas source 101；
The gas that can be connected to tire 100 enters valve 13；
Valve 4 is supplied, supply valve 4 receives gas-pressurized from the entrance 2, and can be configured at least in enabling shape
State and state is not enabled, when being in enabling state, which, which enters valve 13, allows pressurized gas pulses to pass through, in not enabling
When state, which enters the conveying for the pressurized gas pulses that valve 13 is closed to the tire 100；
Calibration valve 5, calibration valve 5 operationally act on supply valve 4, for having more than preset when pulse
When maximum pressure value, which is switched to from enabling state and does not enable state.
It includes valve body 8 to supply valve 4, and formed therein that have a first chamber 9 and second chamber 10, first chamber 9 be used for
The entrance 2 of gas-pressurized is connected, which (for simplicity, hereinafter referred to as " is gone out by outlet conduit 3
Mouthful ") be connected with inlet for gas valve 13.
Closure member 11 is located in the valve body 8, which has elongated shape, and is arranged on accommodating chamber 12
In, which is formed in valve body 8 and is internally located between first chamber 9 and second chamber 10.
Closure member 11 can between the first position and the second position move inside accommodating chamber 12：
When in first position, closure member 11 is realized from first chamber 9 to the local channel of the gas of second chamber 10,
So that supply valve 4 is in enabling state, and
When at the second position, which blocks the fluid communication between first chamber 9 and second chamber 10,
So that supply valve 4 is in and does not enable state.
Feeding mechanism 1 advantageously comprises the bypass channel 6 for being provided with throttling element 7, and bypass channel 6 goes out the entrance 2 with this
Mouth 3 is in fluid communication.
Throttling element 7 preferably has diameter in the range of 0.10mm to 0.50mm, and having prevents entrance 2 and outlet 3
Between the too fast purpose of pressure compensation.
In the embodiment shown in fig. 4, bypass channel 6 is molded in valve body 8, and extends to from first chamber 9
Two chambers 10.
In one of them alternative embodiment (not shown), bypass channel 6 is by the pipeline group in the outside of valve body 8
At connection entrance 2 and outlet 3.
The operation according to the present invention for the feeding mechanism by gas-pressurized supplied to tire is described below.
In the curling step of tire 100, gas inlet valves 13 are opened, and gas-pressurized arteries and veins is enabled by supplying valve 4
The conveying of punching-supply valve 4 is in enabling state.In fact, pressurized gas pulses reach outlet conduit 3, outlet conduit 3 passes through
Gas inlet valves 13 are connected to tire 100.
Bypass channel 6 allows air-flow to pass through between entrance 2 and outlet 3, but this does not interfere with crimping.
When the curling step of tire 100 is completed, i.e., when tire 100 has reached calibrating (base measuring) pressure, gas inlet valves 13 close
Close, and supply valve 4 be in do not enable state so that it no longer generates the gas pulses of exit 3.
Since there are bypass channel 6, entrance 2 and outlets 3 to be in fluid communication so that the gas pressure at outlet 3 is rapidly achieved
Gas pressure at entrance 2, for example, 8-10 bars.
In this way, in the downstream of supply valve 4 there is no the decline of pressure (pressure is about 8-10 bars always), it therefore, will not
Cause the formation of pulse again.
Differently, in Fig. 1 to solution shown in Fig. 2, at the end of curling step, entrance and exit is to be isolated
It opens, i.e., they are under different pressure, are respectively about 8-10 bars and about 4.2 bars, and in 4 downstream of supply valve
Any leakage triggers the recovery of the device.
By the description provided, the feature according to the present invention for the feeding mechanism by gas-pressurized supplied to tire
It becomes apparent, advantage also becomes apparent.Specifically, the presence of the bypass channel with throttling element makes it possible to keep entrance and go out
Mouth is in fluid communication.In this way, at the end of curling step, the leakage of any outlet is compensated by inlet pressure.
