Embodiment
The exemplary embodiment embodying feature of present invention and advantage will describe in the following description in detail. Iting should be understood that the present invention can have various changes in different enforcement modes, it does not all depart from the scope of the present invention, and explanation wherein and to be shown in be use when explain in essence, and is not used to restriction the present invention.
Consult Fig. 2, the present invention proposes a kind of vehicle, it is provided with pneumatic emergency trip valve 2, this vehicle also comprises: the valve emergency switching-off system 3 being applied on pneumatic emergency trip valve 2 and the electrically controlled brake system 4(ElectricBrakingSystem in order to control vehicle braking, referred to as EBS).
This vehicle is pot type transport trolley, and pneumatic emergency trip valve 2 is connected with the outlet of the tank body 1 of pot type transport trolley, thus prevents the medium in tank body 1 from arbitrarily discharging. In other embodiments, this vehicle also can be semitrailer, and pneumatic emergency trip valve 2 is connected with the outlet at bottom of semitrailer.
Pneumatic emergency trip valve 2 has valve body and pneumatic head, and pneumatic emergency trip valve 2 has two kinds of using states of opening and closing: when pneumatic head is connected with gas source, valve body is opened, and the outlet of tank body 1 is opened, thus makes the medium in tank body 1 exportable; When pneumatic head and gas source disconnect, valve body is closed, and the outlet of tank body 1 is closed, thus the medium in tank body 1 cannot export.
The core of the present invention is valve emergency switching-off system 3, the valve emergency switching-off system 3 consulting Fig. 2 by continuing below and the present invention is described in detail.
Valve emergency switching-off system 3 comprises: accumulator unit 31, manually operated control valve 32, speed detection unit (not shown), electronically controlled unit 33(ElectronicControlUnit, referred to as ECU), magnetic valve 34, promptly continue two release valve 35 and stopping valve 36.
Accumulator unit 31 is by being connected with pneumatic emergency trip valve 2 for air circuit, and carries air supply source for pneumatic emergency trip valve 2. When for the gas source in air circuit current time, the pneumatic head of pneumatic emergency trip valve 2 is connected with gas source, and pneumatic head is bullied source driving and pneumatic emergency trip valve 2 is opened. When being cut off for air circuit, the pneumatic head of pneumatic emergency trip valve 2 and gas source disconnect, and pneumatic head cannot be actuated to pneumatic emergency trip valve 2 cuts out because losing gas source.
Manually operated control valve 32 is arranged on cutting out on air circuit with Non-follow control pneumatic emergency trip valve 2 or opening between pneumatic emergency trip valve 2 and accumulator unit 31. Specifically, manually operated control valve 32 is two-bit triplet mechanical valve, comprising: an inlet mouth, an emptying mouth, an air outlet and a manual control end. The air outlet of manually operated control valve 32 is connected with pneumatic emergency trip valve 2. By handling Non-follow control end, manually operated control valve 32 is opened or closed. When manually operated control valve 32 is opened, the inlet mouth of manually operated control valve 32 is connected with the air outlet of himself, passing through for the gas source in air circuit, the pneumatic head of pneumatic emergency trip valve 2 source of being bullied drives and pneumatic emergency trip valve 2 is opened, and at this moment the medium in tank body 1 is exportable.When manually operated control valve 32 cuts out, the air outlet of manually operated control valve 32 is connected with the emptying mouth of himself, release is for gas source in air circuit (being namely cut off for air circuit), the pneumatic head of pneumatic emergency trip valve 2 cannot be actuated to pneumatic emergency trip valve 2 cuts out because losing gas source, and at this moment the medium in tank body 1 cannot export.
The traveling speed of speed detection unit detection vehicle, electronically controlled unit 33 is connected with speed detection unit communication. When Vehicle Speed is more than a set(ting)value, electronically controlled unit 33 outwards sends valve cutting-off controlling signal. Specifically, this set(ting)value is 5km/h, and the setting of this set(ting)value is intended to judge whether vehicle is in traveling state, but in other embodiments, this set(ting)value can increase and decrease according to practical situation. Electronically controlled unit 33 and speed detection unit are integrated in electrically controlled brake system 4.
Magnetic valve 34 is arranged on supplying in air circuit between manually operated control valve 32 and accumulator unit 31. Magnetic valve 34 is connected with electronically controlled unit 33 communication. Magnetic valve 34 receives above-mentioned valve cutting-off controlling signal and cuts out, and to cut off for air circuit (namely release is for the gas source in air circuit), is closed by pneumatic emergency trip valve 2. Magnetic valve 34 is two-bit triplet magnetic valve, comprising: an inlet mouth, an emptying mouth, an air outlet and a controlled end. The inlet mouth of magnetic valve 34 is connected with accumulator unit 31, and the air outlet of magnetic valve 34 is connected with the inlet mouth of manually operated control valve 32, and controlled end is connected with electronically controlled unit 33 communication, so that magnetic valve 34 is controlled by electronically controlled unit 33 and opens and closes. When magnetic valve 34 is opened, the inlet mouth of magnetic valve 34 is connected with the air outlet of himself, for the gas source in air circuit pass through, the pneumatic head of pneumatic emergency trip valve 2 be bullied source drive and pneumatic emergency trip valve 2 is opened, at this moment the medium in tank body 1 is exportable. When magnetic valve 34 cuts out, the air outlet of magnetic valve 34 is connected with the emptying mouth of himself, release is for gas source in air circuit (being namely cut off for air circuit), the pneumatic head of pneumatic emergency trip valve 2 cannot be actuated to pneumatic emergency trip valve 2 cuts out because losing gas source, and at this moment the medium in tank body 1 cannot export.
Two release valve 35 that promptly continues is connected with accumulator unit 31 to maintain accumulator unit 31 stable gas pressure.
Stopping valve 36 is connected with pneumatic emergency trip valve 2.
The manually operated control valve 32 of the present invention and magnetic valve 34 all can cut off for air circuit thus be closed by pneumatic emergency trip valve 2, but manually operated control valve 32 needs operator's manual operation, magnetic valve 34 does not need operator's manual operation and Negotiation speed detecting unit and electronically controlled unit 33 intelligence operate. When vehicle is in traveling state, close or surprisingly open as occurred that manually operated control valve 32 is forgotten thus fail to close pneumatic emergency trip valve 2, at this moment speed detection unit detects the traveling speed of vehicle, electronically controlled unit 33 outwards sends valve cutting-off controlling signal, magnetic valve 34 receives valve cutting-off controlling signal and cuts out, to cut off for air circuit (namely release is for the gas source in air circuit), thus pneumatic emergency trip valve 2 cuts out. In brief, working as vehicle operating, even if occurring that manually operated control valve 32 does not cut out or unexpected unlatching situation, magnetic valve 34 discharges automatically for the gas source in air circuit, runs vehicle to avoid under pneumatic emergency trip valve 2 opened condition, ensures safe operation.
Although describing the present invention with reference to exemplary embodiment, it should be understood that term used illustrates and exemplary but not restrictive term.Spirit or the essence of invention is not departed from owing to the present invention can specifically implement in a variety of forms, so being to be understood that, above-mentioned enforcement mode is not limited to any aforesaid details, and should explain widely in the spirit and scope that claim of enclosing limits, therefore fall into the whole change in claim or its equivalent scope and remodeling all should be claim of enclosing and contained.
