Definitions
- the invention relates to a circuit arrangement for a fluid-operated door with the features of the preamble of claim 1.
- Working group and emergency circuit are designed in a conventional manner to allow the working group a repeated, pressure medium-actuated opening and closing and the emergency circuit either a fluid-operated, automatic irreversible opening or DrucklosTER the door for a manual opening.
- To switch from the working group to the emergency circuit are especially in buses from inside and outside operable emergency valves provided with which in an emergency situation of the working group can be switched to the emergency circuit to open the door regardless of activation by the driver can.
- the emergency operation is triggered upon actuation of the emergency valve and by a pressure build-up of the pressure medium, a positive circuit causes, with the valve circuit from the working group on the emergency circuit.
- an emergency valve integrated in the pressure medium circuit for actuating the door is necessary, which has the corresponding inlets and outlets to the door or to the door drive, wherein a plurality of provided emergency valves must be linked together accordingly.
- the present invention is based on the object, a circuit arrangement in such a way that the generation and the triggering of an emergency operation are decoupled.
- the valve device for switching the working valve consists of an actual control valve which switches the working valve via a pressure line and an emergency valve, when actuated by the pressurization of Working valve can be drained via the pressure line.
- the control valve is zwangsschaltbar between a position for activating the pressurization of the working valve and a position for latching this pressurization. Where under zwangsschaltbar an external pressure medium independent circuit is to be understood. In the position of holding the pressurization of the control valve, this pressurization can be released by actuation of the emergency valve, whereby the actuation of the working valve and the associated switching position are canceled.
- an emergency valve does not have to be connected via lines to the pneumatic system of the door, which are suitable for conveying pressure medium for actuating the door, or not integrated into the lines for actuating the door.
- lines to the pneumatic system of the door which are suitable for conveying pressure medium for actuating the door, or not integrated into the lines for actuating the door.
- the emergency valve is connected via a spur line to the pressure medium circuit for latching the pressurization in the pressure line for switching the working valve and open to the atmosphere. Upon actuation of the emergency valve, the pressure is released from the pressure medium circuit and necessary for switching the working valve pressurization is no longer given. It is also useful in the pressure medium circuit for latching the pressurization to provide a throttle to control at a supply of this pressure medium circuit from the pressure medium supply a subsequent flow of the pressure medium in dependence on the throttle cross-section.
- control valve is a 3/2-way valve, with which the pressure valve acting on the working line can be connected to either the circuit for activating the pressurization or the circuit for latching the pressurization with the possibility of releasing the pressure.
- the control valve is further switchable in particular by energization against a return device, wherein the control valve is switched by the energization in the position of activation of the pressurization, since this is a temporary operation, while the control valve can remain in operation in the position for latching the pressurization , In this latching the control valve remains energized and the circuit operates in the workgroup to open and close doors to the time when an emergency valve is actuated.
- the control valve can also be switched, for example, for maintenance without energization by hand.
- the working valve is a 5/2-way valve which can be switched by the pressure line against a return action from the emergency circuit into the working circuit.
- the circuit is so long in the working group, as the working valve is acted upon by the pressure medium. In case of elimination of this pressure medium, especially when depressurized by actuation of the emergency valve is done by the reset effect automatically switching to the emergency circuit Further valve connections of the valve are provided for venting the working cylinder for actuating the door.
- the pressure medium circuit for latching the pressurization in the pressure line has a pressure sensor, with which a pressure drop, in particular upon actuation of a Nothahns is detectable. With the arrangement of the pressure sensor in the pressure medium circuit, this detection is carried out centrally and includes all both inside and outside arranged emergency valves whose respective operation leads to a pressure change in the monitored by the pressure sensor line.
- a deactivation of the emergency valve by means of an interrupter valve in the stub is provided in the invention.
- the emergency valve can be disabled without taking any influence on the pressure medium circuit to keep the pressurization on the working valve.
- Particularly advantageous in the circuit arrangement according to the invention is a pneumatic pressure medium actuation.
- 1 shows the circuit arrangement in the position for activating the latching of the system
- 2 shows the circuit arrangement in the operating position in latching system
- Fig. 4 shows the circuit arrangement with an additional path lock.
- the circuit arrangement shown in Figure 1 relates to the section of a pneumatic circuit of a bus, which is necessary for activating the emergency operation circuit for actuating the doors.
- the necessary pneumatic circuits for this purpose correspond with higher-level circuits and are integrated into the pneumatic system of the bus.
- the circuit for actuating the door 10, shown only schematically, is supplied via a line 12 from a supply 14 of the bus circuit and is secured against the bus cycle by the check valve 16.
- the door 10 can be supplied via the 5/2-way valve 18 via the line 20 in a known working mode or via the line 22 in a likewise known emergency operation.
- the supply lines are shown only schematically, since these two modes of operation take place in a conventional manner.
- the system can be switched from the operating mode shown in Figure 1 to the emergency operation via the then controllable line 22.
- the working valve 18 is pneumatically connected via the pressure line 24.
- the working valve 18 as a return action, a spring 26, which is missing Pressurization in the pressure line 24, the working valve 18 switches to the position for emergency operation.
- the working valve 18 By energizing the control valve 28, the working valve 18 is switched to the operating mode shown in Figure 1 on the pressure line 24 so durbbeaufschlagte. In this switching position of the working valve 18, the line 22 for the emergency operation of the door 10 is connected to a vent 33.
- control valve 28 The energization of the control valve 28 is only the activation of latching for the circuit in the emergency operation, which is shown in Figure 2.
- the circuit switches to the operating position in latching, with the end of the energization, the working valve 28 is switched by the spring 30 in its second position in which the pressure line 24 and the control valve 28 to the branch 34 of the supplied in working mode line 20 are connected to latch the circuit.
- the circuit for latching is secured via a arranged in the line 34 check valve against the line 20 and thus against the working circuit for operating the door.
- the working valve 18 is subject to switching off the energization of the control valve 28 of a pneumatic latching via the lines 34 and 24th
- the circuit has an emergency throttle 36 designed as a emergency button, which is connected via a branch line 38 to the line 34 of latching.
- the emergency valve 36 is designed as a 2/2-way valve and opens when actuated the spur line 38 and connected to this line 34 of the latching against the atmosphere.
- By pressing the emergency valve 36 escapes the pressure medium from the stub 38 and the circuit of the control valve 28 and the pressure line 24, whereby the pressurization and the resulting circuit of the working valve 18 is repealed.
- a Nachstromen of pressure medium via the line 34 for latching is limited by a arranged in this line throttle 40.
- the emergency cock 36 shown in FIG. 2 exemplarily represents additional emergency dogs, not shown, which are each connected via separate branch lines to the line 34 and can be actuated either inside the bus or from the outside.
- the stubs of the emergency cream could also be connected to the pressure line 24.
- a connection of the various emergency cream with each other is not necessary by the connection via spurs.
- a control of the operation of the emergency valve 36 via a pressure sensor 42, the parallel via a stub 44 is connected to the stub 38 of the emergency valve 36 to the latching.
- the line 22 of the emergency operation of the door 10 is supplied via the line 12 and the working valve 18 in this switching position, in which this is either automatically opened or can be opened manually.
- the working cylinder of the door 10 is vented through the vent door 46.
- the fed via the supply 14 branch 32 is locked to the control valve 28 with the completion of its energization.
- the operating position with response of the working group can be re-activated from the circuit emergency operation by the energization of the control valve 28 according to the circuit described for Figure 1.
- a manual circuit may be provided for the valve 28, with which the valve can be switched independently of the power supply. In certain situations deactivation of the emergency function may make sense.
- the working valve 28 can be energized in the operating position shown in Figure 2, so that the pressure line 24 acting on the working valve 18 is permanently supplied by the supply 14 via the branch 32 and an actuation of the emergency valve 36 has no effect, since there is no connection to the pressure line 24 in this switching position of the control valve 28 and an excessive pressure medium discharge from the working group via the throttle 40 is prevented.
- a pulsed switchable 2/2-way valve 48 can be arranged as a breaker valve to realize a parking brake, with the opening of the doors on the operation of one of the outside mounted emergency cream is to be prevented in the stub of an emergency valve the corresponding circuit, a pressure release from the pressure line 24 can be prevented to activate the emergency operation.
- the switching of the valve 48 has in the exemplary embodiment, a pneumatic switching support and is connected via a spur line 45 to the line 32, wherein the connection with the same effect can also be made to the line 12.
- the control valve 28 When the parking brake is removed, the control valve 28 is briefly energized analogously to the circuit according to FIG. 1 in order to prevent an unintentional pressure drop and a resulting switching to emergency operation, in order to ensure the forced switching to the working valve 18. With a minimum time delay then the valve 48 is pulsed to restore the connection to the emergency valve 36 and the latching of the emergency operation after completion of the energization of the control valve via the second switching position of the valve 48.
- an external lug in the form of a key switch behind the front flap of the bus may be arranged to use a key to switch the circuit arrangement in an emergency operation can.
- the emergency valves 36 connected to this section can each be connected via simple, low-volume stub lines, as well as a pressure sensor, which can also be connected directly to the line.
- the present invention it is thus possible to separate the working and emergency lines (20, 22) from the control lines of the emergency valves and thus to decouple the generation or triggering of the emergency operation.
- the triggering of the emergency operation can be carried out in the claimed circuit arrangement by a pure negative circuit with pressure relief, so that no lines for a pressure build-up or a coupling of the emergency valves with each other are necessary.
- the distributed Notphohne (36) for triggering the emergency operation are not directly integrated into these lines, but cause by a targeted pressure relief in the pressure line (24) switching the working valve (18) in the emergency operation.
- the ventilation of the lines for work and emergency operation can also be time-optimized, as arranged in the interior or on the outside of the vehicle distributed for passenger transport emergency valves are not integrated directly into the lines for operating the door and thus the for the ventilation system to be flowed through can be arranged with the control devices compact in the vicinity of the door or the door drive. With the shorter paths and the flow resistance in the lines and thus the pressure losses occurring is kept low.
