Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, bore N vent hole 5 on wheel rim 2, gas is communicated with the operation valve 3 of exitting through separately wireway 4 by N vent hole 5 in the tire 1, and the utility model N is eight vent holes.
Shown in Figure 3 as Fig. 1, Fig. 2, described venting operation valve 3 comprises operation valve base 8, application valve body 11, venting cavity 16 and air discharge cavity lid 12; Have on the operation valve base 8 of control chamber B one end application valve body 11 is installed successively, venting cavity 16 and air discharge cavity lid 12, in the application valve body cross section being installed is I-shaped slide block 9, be positioned on the application valve body 11 of 9 of slide blocks and have open to atmosphere leakage port 10, slide block 9 one sides are communicated with the control chamber B of operation valve base 8, slide block 9 opposite sides are communicated with the air discharge cavity A of venting cavity 16, having seven vent holes on the venting cavity 16 is communicated with seven wireways respectively, operation valve base 8 radially has vent hole, one end of vent hole is communicated with the 8th wireway, the other end of vent hole is communicated with the control chamber B of operation valve base 8 through two-bit triplet solenoid valve 6, two-bit triplet solenoid valve 6 realizes that control chamber B is communicated with the 8th wireway or control chamber B communicates with atmosphere, and two-bit triplet solenoid valve 6 passes through teleswitch 14 by battery 13, lead 7 power supplies; Venting operation valve 3 is connected with the wheel coupling bolt by operation valve base 8, is installed on the wheel.
Principle of work of the present utility model is as follows:
Two-bit triplet solenoid valve 6 as shown in Figure 3, it is used for switching controls chamber B and is connected with the 8th wireway and also is connected with atmosphere.Under normal conditions, two-bit triplet solenoid valve 6 is in that control chamber B and atmosphere cut off and the state that is connected with the 8th wireway, at this moment control chamber B internal pressure equates with tire pressure, air discharge cavity A internal pressure with equal tire pressure, because the area of control chamber one side of slide block 9 is greater than air discharge cavity A one lateral area, therefore slide block 9 is crushed on the venting cavity 16, and so then gaseous tension is constant in the tire; Blow out when needs and to lose heart or fast during gas leakage test, telepilot 17 sends the connection circuit signal, the teleswitch 14 that is placed on the air discharge cavity lid 12 is connected, battery 13 gives the two-bit triplet solenoid valve 6 power supplies, two-bit triplet solenoid valve 6 electric after, control chamber B is communicated with atmosphere, the 8th wireway is cut off, pressure in the control chamber B descends rapidly, at this moment slide block 9 because air discharge cavity A one wall pressure is big to control chamber B one lateral movement, move to until slide block 9 and to open leakage port 10 (all cloth is totally 4 leakage ports), air discharge cavity A communicates with atmosphere, gas releases rapidly from leakage port in the air discharge cavity A, and gas is by seven vent holes 5 in the tire, wireway 4, the leakage port 10 of venting operation valve 3 releases rapidly, realizes blowing out and loses heart or the simulation of gas leakage fast.
