A many valves maloperation early warning system, includes fan -shaped spacer, fan -shaped spacer pass through the bolt and twist on the pipeline, fan at fan -shaped spacer is fixed with operating handle to the department coaxially, and operating handle can drive fan -shaped spacer and remove, be fixed with rectangle micro -gap switch on the sector of fan -shaped spacer, rectangle micro -gap switch's the lower right corner be fixed with sensor ball, and rectangle micro -gap switch's the lower right corner and the contact of the lower limb of fan -shaped spacer, be provided with the gland bolt on the pipeline, the gland bolt be located the horizontal direction, micro -gap switch passes through line connection programmable controller (PLC).
Description
Technical field
This utility model relates to a kind of pipeline valve maloperation early warning system, is specifically related to a kind of Chemical Manufacture pipeline valve maloperation early warning system.
Background technology
During modern chemical industry produces, pipeline is intricate, and valve is more, easily occurs operation mistake causing the phenomenon such as material leakage, flushing, can cause the generation of accident time serious during workman's controlled valve.
Based on the problems referred to above, a kind of novel misoperation of valve early warning system is invented in design, and when the wrong operational motion of valve, the audible-visual annunciator of native system sends alarm, and the workman of notice operation valve repairs malfunction in time.
Summary of the invention
This utility model is for the deficiencies in the prior art, it is provided that a kind of ball valve switch structure equipped with microswitch, and this structure combines with PLC (programmable controller) and audible-visual annunciator and then forms many misoperation of valve early warning system.
To achieve these goals, the concrete technical scheme that the application takes is:
A kind of many misoperation of valve early warning system, including fan-shaped spacer, described fan-shaped spacer is screwed on pipeline by bolt；Fan at fan-shaped spacer is fixed with operation handle coaxially place, and operation handle can drive fan-shaped spacer to move；Being fixed with rectangle microswitch on the covering of the fan of fan-shaped spacer, the lower right corner of described rectangle microswitch is fixed with induction sphere；And the lower right corner of rectangle microswitch contacts with the lower limb of fan-shaped spacer；Being provided with gland stud on pipeline, described gland stud is positioned in horizontal direction；Microswitch passes through connection Programmable Logic Controller (PLC)；
Described Programmable Logic Controller (PLC) is provided with alarm；
Described fan-shaped spacer, when switch is closed, its lower limb is horizontally oriented, and contacts with gland stud；When switch is in open mode, its lower edge is in vertical direction, and does not contact with gland stud；
When switch is closed, the lower limb of fan-shaped localizer contacts with gland stud, so the induction sphere in the rectangle microswitch lower right corner will contact with gland stud, induction sphere perceptual signal, and then pass the signal along to PLC by circuit, when not being inconsistent with PLC pre-set programs, namely there is alarm signal, thus avoiding the generation of switching manipulation mistake.
In sum, adopt many misoperation of valve early warning system provided by the utility model, valve switch mistake can be avoided the occurrence of, and the material leakage because maloperation causes, flushing can be prevented, mix accidents such as criticizing.

Accompanying drawing labelling
In figure, 1 is fan-shaped spacer, and 2 is rectangle microswitch, and 3 is circuit, and 4 is alarm, and 5 is Programmable Logic Controller (PLC), and 6 is induction sphere, and 7 is gland stud, and 8 is operation handle.
Detailed description of the invention
A kind of many misoperation of valve early warning system, including fan-shaped spacer 1, described fan-shaped spacer 1 is screwed on pipeline by bolt；Fan at fan-shaped spacer 1 is fixed with operation handle 8 coaxially place, and operation handle 8 can drive fan-shaped spacer 1 to move；Being fixed with rectangle microswitch 2 on the covering of the fan of fan-shaped spacer 1, the lower right corner of described rectangle microswitch 2 is fixed with induction sphere 6；And the lower right corner of rectangle microswitch 2 contacts with the lower limb of fan-shaped spacer 1；Being provided with gland stud 7 on pipeline, described gland stud 7 is positioned in horizontal direction；Microswitch 2 connects Programmable Logic Controller (PLC) 5 by circuit 3；
Described Programmable Logic Controller (PLC) 5 is provided with alarm 4；
Described fan-shaped spacer 1, when switch is closed, its lower limb is horizontally oriented, and contacts with gland stud 7；When switch is in open mode, its lower edge is in vertical direction, and does not contact with gland stud 7；
When switch is closed, the lower limb of fan-shaped localizer contacts with gland stud, so the induction sphere in the rectangle microswitch lower right corner will contact with gland stud, induction sphere perceptual signal, and then pass the signal along to PLC by circuit, when not being inconsistent with PLC pre-set programs, namely there is alarm signal, thus avoiding the generation of switching manipulation mistake.
In sum, adopt many misoperation of valve early warning system provided by the utility model, valve switch mistake can be avoided the occurrence of, and the material leakage because maloperation causes, flushing can be prevented, mix accidents such as criticizing.
