Description
Technical field
The utility model relates to the Safeguard that a kind of combustion gas is used, and relates in particular to a kind of gas valve timer.
Background technique
Combustion gas has brought great easy to life as the use of the energy, usually on the domestic gas pipeline after house lead in, manual gas valve only is housed, the combustion gas usage requirement of safety be each with after depressed bundle, throttle down cut-out source of the gas, prevent gas leakage.People in use can't set the time of automatic-closing valve according to using the gas situation in addition, and such as when stewing or heat up water, easily forgetting and close cooking stove etc., annual often have because the security incident that the combustion gas improper use causes.Existing mechanical gas Timed valve shutoff device, be fixedly mounted on gas valve, can not set intuitively the length of closing valve time, and the running state of gas timing valve door closing device also can not get real-time monitoring.
The model utility content
The utility model purpose is in order to overcome deficiency of the prior art, and a kind of easy to operate, gas valve timer intuitively regularly is provided.
The utility model is achieved by following technical proposals: a kind of gas valve timer, comprise the valve rod actuator that is arranged on the moving gas valve Spool rotating in gas pipeline upper erengy band, the reduction gear box driven by direct current motor is connected with valve rod actuator gear, shell, control chip input pin 1 to 5 connects respectively the valve turn on sensor, the valve closure sensor, time switch, increase key and reduce key, its output pin 6 to 9 connects respectively changes the battery display lamp, valve is not opened display lamp, valve does not cut out display lamp, the input end of motor polarity switch, the output terminal of motor polarity switch connects direct current motor, control chip feeder ear 10 connects power supply, control chip shows that output terminal 11 connects digital display tube.
Described power supply is the DC electrical source that battery forms.Described control chip is single-chip microcomputer.
Described replacing battery display lamp, valve are not opened display lamp, valve does not cut out display lamp, time switch, increase key and reduces key and is installed on shell.The remaining part of gas valve timer all is arranged in shell, and shell is fixedly mounted on gas pipeline.
The gas valve rotatable handle is housed on shell, can manually carries out the adjusting of shutoff, unlatching or the tolerance of gas valve.
The utility model has the advantages that:
1, regularly directly perceived, monitoring in real time.
2, easy to operate, simple in structure.
The accompanying drawing explanation
The electrical connection schematic diagram that Fig. 1 is the utility model gas valve timer.
Embodiment
For the purpose, technological scheme and the advantage that make the utility model embodiment clearer, below in conjunction with the accompanying drawing in the utility model embodiment, technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiments.
The electrical connection schematic diagram that Fig. 1 is the utility model gas valve timer.A kind of gas valve timer, comprise the valve rod actuator that is arranged on the moving gas valve Spool rotating in gas pipeline upper erengy band, the reduction gear box driven by direct current motor is connected with valve rod actuator gear, shell, control chip 21 input pin 1 to 5 pin are connection valve turn on sensor 22 respectively, valve closure sensor 23, time switch 24, increase key 25 and reduce key 26, its output pin 6 to 9 connects respectively changes battery display lamp 27, valve is not opened display lamp 28, valve does not cut out display lamp 29, the input end of motor polarity switch 30, the output terminal of motor polarity switch connects direct current motor 31, control chip 21 feeder ears 10 connect power supply 32, control chip 21 shows that output terminal 11 connects digital display tube 33.
Concrete, described power supply 32, for the DC electrical source that battery forms, is preferably 6V or 9V power supply.Described control chip 21 is single-chip microcomputer, and model is PIC16F883.
Described replacing battery display lamp 27, valve are not opened display lamp 28, valve does not cut out display lamp 29, time switch 24, increases key 25 and reduces key 26 and is installed on shell.
Further, in 3 display lamps on the gas valve timer, change the battery display lamp bright when the power supply brownout; When gas valve is opened, not open display lamp not bright for valve; It is bright that when gas valve is not closed, valve does not cut out display lamp.Display lamp is all in extinguishing state under normal circumstances.
During use, set the gas valve timer turn-off time, by time switch, enter gas valve timing setting state, 3 nixie tubes show flicker, show that after a while 20 for 20 minutes default setting time, press and increase key or reduce key and can adjust time range between 1 to 999 minute.After set time finishes, 3 nixie tubes show the countdown state that enters, and control chip starts the direct current motor signal to the motor polarity switch simultaneously, and the external air feed of gas valve is opened by reduction gear box band ovable valve stem actuator.Now, if when replacing battery display lamp is bright, gas valve is not opened.
In gas valve timer working procedure, pin the increase key and can extend the turn-off time of setting, unclamp button and stop increasing; Pin and reduce the turn-off time that key can shorten setting, unclamp button and stop reducing.Adjust after-burning timing of valve device and press the turn-off time operation of new settings.
Arrived the turn-off time of setting, control chip, to motor polarity switch signal, starts direct current motor, by reduction gear box band ovable valve stem actuator closing gas valve, stops air feed.
Further, in the work of gas valve timer and holding state, all can realize real-time monitoring continuously for power supply voltage, the valve situation such as whether open on request or close, and remind the user by corresponding display lamp.
The gas valve rotatable handle is housed on the shell of gas valve timer, can manually carries out the adjusting of shutoff, unlatching or the tolerance of gas valve.
The utility model gas valve timer, for abnormal conditions, also can provide sound alarm simultaneously, is equipped with gas leakage, temperature over-temperature sensor etc., with more convenient multipath prompting user's safety operation.The utility model also can be widely used on the conveyance conduits such as the gas that need to regularly close, liquid.
