Abstract
The utility model relates to a counter used for on-off number of turns of a manually-operated valve. The counter is characterized in that an instrument box is provided with a counter and a proximity switch. An input end of the counter is connected with an output end of the proximity switch. An output end of the counter is connected with an input end of the proximity switch. An end of the counter is connected with a power supply. When the counter is used, the power supply supplies power for the counter, and counting results of the counter are displayed on a nixie tube panel. Switching value signals are input from the counter. The switching value signals are acquired by the proximity switch which can contact with the external, and the counter counts to complete calculation of number of turns of opening a valve. The counter can record accurate number of turns when manually open the valve. If the valve cannot rotate when the valve is not closed in place, fault cause can be founded and detected by the counter in time, thereby preventing abnormity of production technology and potential safety hazard.
Description
Technical field
The utility model relates to the technical field of counter, specifically a kind of counter that opens and closes the number of turns for manually-operated gate.
Background technology
At present, because the valves such as hand switch atmospheric valve cannot definitely record the unlatching number of turns, once manually not close, just put in place cannot rotary state, and need to investigate be one by one that valve has produced fault, waste time and energy, cannot find in time the potential safety hazard in production technology, affected production efficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of improved counter that opens and closes the number of turns for manually-operated gate, it can overcome the valve such as hand switch atmospheric valve in prior art cannot definitely record the unlatching number of turns, cannot find in time the some shortcomings of the potential safety hazard in production technology.
To achieve these goals, the technical solution of the utility model is: a kind of counter that opens and closes the number of turns for manually-operated gate, it mainly comprises instrument case, it is characterized in that: in instrument case, be provided with counter and universal switch, the input end of counter is connected with the output terminal of universal switch, the output terminal of counter is connected with the input end of universal switch, and one end of counter is connected with power supply.
When use, Power supply is to counter, then by counter, the result of counting is presented on charactron panel, by counter input switch amount signal.Switching value signal, by gathering with the universal switch of external contact, is then counted, and completes the calculating of the Open valve number of turns.Just can record the definite number of turns when manually opened, not close that just put in place cannot rotary state as found, just failure cause is found and checked to counter in time whereby, thus avoid bringing production technology extremely and potential safety hazard.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one embodiment.
Embodiment
Below in conjunction with drawings and Examples, the utility model will be further described.
Label in accompanying drawing is expressed as follows: 1 counter, 2 approach switchs, 3 power supplys, 4 charactron display panels, 5 reset switches, 6 power switches, 7 magnet.
A kind of counter that opens and closes the number of turns for manually-operated gate described in the utility model, it mainly comprises instrument case, its difference with the prior art is: in instrument case, be provided with counter and approach switch, the input end of counter is connected with the output terminal of approach switch, the output terminal of counter is connected with the input end of approach switch, and one end of counter is connected with power supply.
Counter is connected with a charactron display panel, and the counting clear terminal of counter is connected with the input end of approach switch, between the counting clear terminal of counter and the input end of approach switch, is provided with a reset switch.Line between power supply and counter is provided with power supply Katyuan, and described power supply is the Switching Power Supply of 9V battery supply or 9-18v.The demonstration of employing charactron is low in energy consumption, font is large, brightness is high, under the sun, also can use.
In enforcement, Power supply is to counter, then by counter, the result of counting is presented on charactron panel, by counter input switch amount signal.Switching value signal is by gathering with the approach switch of external contact, and magnet adsorption is fixed on the manual turntable of valve, when rotating disk often turns around, magnet contact approach switch once, approach switch sends a switching value signal, and then counter is counted, and completes the calculating of the Open valve number of turns.Just can record the definite number of turns when manually opened, not close that just put in place cannot rotary state as found, just failure cause is found and checked to counter in time whereby, thus avoid bringing production technology extremely and potential safety hazard.
