Abstract
The present invention discloses one kind of steel cylinder warning device for indicating the operation state of steel cylinder to avoid error operation. The steel cylinder warning device includes one light alarm mounted near the steel cylinder to indicate its operation state, one switch of solenoid valve connected to the light alarm for controlling the on-off of the alarm, and one programmable controller to control the switch based on the operation state of the system.
Description
Technical field
The present invention relates to the safety installations of a kind of special gas system, relate in particular to a kind of signalling device that is applied to steel cylinder.
Background technique
In the actual motion operating process of present special gas system, the accident of tearing wrong steel cylinder open through regular meeting, wrong such as the steel cylinder that will normally supply gas as empty steel cylinder, the steel cylinder joint is taken apart, and cause gas leakage.
At the problems referred to above, the factory that has has added the fool proof protection in the steel cylinder joint, in fact just increases the step of operation, rather than indicate which be the sky steel cylinder which be the steel cylinder of supplying gas.
Summary of the invention
Technical problem to be solved by this invention provides a kind of signalling device that is applied to steel cylinder, and it can indicate the working state of current steel cylinder, shows the empty steel cylinder of current steel cylinder formula or the steel cylinder of supplying gas, and then can prevent misoperation.
In order to solve above technical problem, the invention provides a kind of signalling device that is applied to steel cylinder, a warning device is used to show the working state of current steel cylinder, be installed in described steel cylinder near; A switch links to each other with warning device, is used to control the opening and closing of warning device; A controller carries out the action of control switch according to current system works situation.
Described controller is a programmable controller.
Described warning device is the bulb-style warning device.Described switch is a relay.
Described warning device is the cat-eye type warning device.Described switch is a solenoid valve.
Described warning device is installed in the steel cylinder joint.
Because controller can obtain the working state of steel cylinder according to the working condition of current system, pass through control input signals then, and then control the unlatching of warning device, and then show the working state of present steel cylinder.Controller can adopt programmable controller, and such and present system adopts same controller, can save cost.And warning device can adopt bulb-style warning device or cat-eye type warning device, can satisfy the needs of different situations like this.And warning device is installed in the steel cylinder joint, can the staff just must just can operate after taking off warning device like this, thereby make operator must observe the state of warning device.

Embodiment
1-3 describes in conjunction with the accompanying drawings, and the warning device 1 of signalling device of the present invention can be installed on the joint 6 of steel cylinder 5 by magnetic clasp or adhesive tape, and joint 6 is steel cylinder 5 and gas holder joint.The warning device 1 of signalling device can adopt bulb-style or cat-eye type, and as described in Fig. 2,3, bulb-style warning device 11 comprises LED lamp 21, lamp socket 71, the electric wire 8 that links to each other with lamp socket 71 and covers on the anti-explosion cover 9 of LED lamp 21 outsides respectively.And cat-eye type warning device 12 comprises opal 22, opal base 72 and gas-tpe fitting 10.
As shown in Figure 4, it is a logic control flow process schematic representation of the present invention.At first programmable controller (PLC) knows that the steel cylinder in the current system is in running order, when just the signal that obtains from gas cabinet is online (online)/stand by (wait)/Auto Switch (automatic switchover state), PLC is with output signal so, make switch motion, and then unlatching warning device, otherwise when no online (online)/stand by (wait)/Auto Switch (automatic switchover state) signal, the PLC non-output signal, warning device is not worked yet.
Shown in Fig. 5,6, they are respectively the schematic representation of two kinds of different signalling devices of the present invention.As shown in Figure 5, signalling device is made up of programmable controller 3, bulb-style warning device 11 and relay 41, and control by automatically controlled mode this moment.And as shown in Figure 6, signalling device is made up of programmable controller 3, opal warning device 12 and solenoid valve 42, and control by the gas control mode this moment.
Shown in Fig. 7,8, they are respectively warning device working state and off working state schematic representation.As shown in Figure 7, warning device bulb 2 is an illuminating state at this moment, can be red or other eye-catching color, and show this moment cannot operate steel cylinder.As shown in Figure 8, warning device bulb 2 is for extinguishing state at this moment, and show this moment can operate steel cylinder.
