Abstract
The invention discloses a descaling device for a code type prepayment instrument. The instrument is arranged on a delivering pipeline, and a microprocessor CPU is arranged in the instrument. The descaling device is characterized in that a clock circuit is connected with the microprocessor CPU, the microprocessor CPU is also connected with a motor control circuit, and a motor drives a switch of a valve arranged on the delivering pipeline. The descaling device can automatically start the motor to switch the valve at regular intervals according to the practical situation so as to loosen dirt deposited on the valve, clear the dirt accumulated in gaps of the valve, reduce the starting resistance when switching the valve, and eliminate the hidden trouble that the valve cannot be switched because of the increased resistance when the valve needs to be switched. The descaling device ensures that the valve is switched freely, prevents the valve from being plugged and blocked, and avoids unnecessary maintenances and repairs in the later period.
Description
Technical field:
The present invention discloses a kind of apparatus for eliminating sludge that is installed in the code type pre-payment instrument valve on the conveyance conduit, especially a kind of timing automatic apparatus for eliminating sludge.
Background technology:
At present, code type pre-payment instrument is widely used in fields such as tap water, combustion gas, heat supply, and in long-term use, the valve on the pipelines such as the water pipe that instrument is controlled, Gas Pipe can deposit a large amount of dirts, causes valve switch normally.The reason that forms dirt in waterpipe has two kinds: a kind of is that impurity is arranged in the water, the contamination precipitation that long-time water makes is to intellectual water meter valve place, if intellectual water meter is not related to, opens Movable valve in a very long time, then be easy to when needs are with valve closing, the phenomenon that valve is stuck and can not carries out pass valve instruction occurs.Another kind of reason be at the intelligence table under not closing for a long time, starting the situation of work, the valve in the table has a spot of phenomenon of getting rusty, also cause easily with first kind of consequence that reason is the same, thereby restriction people's normal water.The dirt reason that forms in gas pipeline is: because the purity of coal gas is not enough, have the formation of coal tar dirt at the valve place of intelligence table, the friction force of valve in the pass, when opening that forms the coal tar place is big especially, if do not carry out activity for a long time, also will cause intelligent valve when open the pass automatically, to lose efficacy.In case the problems referred to above occur, not only influence the normal use of instrument, make troubles to people's life, and can only deal with problems by changing valve, wasted lot of manpower and material resources, bring extra financial burden to the user.
Summary of the invention:
The present invention is directed to the above-mentioned deficiency of prior art, a kind of regular by-pass valve control switch is provided, the dirt of loosening deposition guarantees the normally apparatus for eliminating sludge of the code type pre-payment instrument of use of valve.
Technical solution of the present invention is: a kind of apparatus for eliminating sludge of code type pre-payment instrument, instrument is installed on the conveyance conduit, be provided with microprocessor CPU in the instrument, be connected with clock circuit with microprocessor CPU, microprocessor CPU also is connected with circuit for controlling motor, and motor-driven is installed in the switch of the valve on the conveyance conduit.
The model of described microprocessor CPU is PIC16F946, its inner integrated timer, storage unit, liquid crystal driver module.
The present invention can be according to actual conditions, regularly automatic starter motor controlled valve, the dirt that deposits on the loosening valve, the dirt that accumulates in the scavenging valve crack between a door and its frame crack, starting resistance when reducing switch valve is eliminated and to be increased the hidden danger that can't move because of resistance when needing controlled valve.Guarantee valve switch freely, prevent valve, avoided unnecessary maintenance, repair of later stage by dirt obstruction, stuck.And by adjusting control program software, can set as required the interval time of each switch valve action, and the time of course of action also can be controlled, according to also setting of valve opening angular dimension, to reach optimum efficiency.
Description of drawings:
Fig. 1 is a schematic block circuit diagram of the present invention.
Fig. 2 is a clocking scheme of the present invention.
Fig. 3 is circuit for controlling motor figure of the present invention.
Embodiment:
Further specify specific embodiments of the invention below in conjunction with accompanying drawing:
Shown in Fig. 1～3, a kind of apparatus for eliminating sludge of code type pre-payment instrument, instrument is installed on the conveyance conduit, is provided with microprocessor CPU in the instrument, and the model of microprocessor CPU is PIC16F946, its inner integrated timer, storage unit, liquid crystal driver module.Be connected with clock circuit with microprocessor CPU, microprocessor CPU also is connected with circuit for controlling motor, and motor-driven is installed in the switch of the valve on the conveyance conduit.As Fig. 3, circuit for controlling motor improves the antijamming capability of circuit by the optocoupler transmission signals.Wherein J11-1, J11-2 are the machine operation signaling interface, and J11-4, J11-5, J11-6 are the motor open and close signaling interface that puts in place.
