Description
Technical field
The utility model relates to the electronic start-stop device of a kind of gas leak, particularly the start-stop device that leaks in liquified petroleum gas cylinder.
Background technique
Combustion gas tool with the liquified petroleum gas cylinder air feed, flexible pipe is aging to break and the kitchen range fault because connect, and usually for causing the leakage of liquid gas, liquid gas is inflammable and explosive and can cause people's poisoning, close in case leak as in time do not realized, often for leading to the serious great misfortune of the injury person and demolition of property.With regard to existing market, though existing multiple gas leakage safety shutoff is all different with the present invention; Be that " cylinder for liquefied gas leak gas automatic alarm closuer " (notification number is CN2492743 Y) of the Chinese utility model patent ZL01229599.X of 07 month 04 day calendar year 2001 discloses a kind of cylinder for liquefied gas automatic alarm closuer that leaks gas as the applying date, it comprises by support and is fixed on shell on the cylinder for liquefied gas valve body, the two-way reducing motor that clutch end links to each other with the handwheel of cylinder for liquefied gas valve, be used to control the electronic control part of reducing motor, described electronic control part comprises control panel, coal gas inductive probe and the buzzer that is used to report to the police.As seen " closer " of this patent is to be directly installed on the shell of cylinder for liquefied gas valve body, and clutch end links to each other with handwheel on the cylinder for liquefied gas; And because existing liquified petroleum gas cylinder valve is the screw type stop valve, the opening and closing valve is to realize by rotary screw, and the open and close number of turns and the angle of every valve handle are not quite similar, so power motor very difficult and as switch valve matches, not being that motor torsion is crossed senior general's valve and damaged, is exactly that valve has been closed and motor is still burnt in work; Say again, open existing problems too again.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of at above-mentioned prior art deficiency to be realized by the electronic start-stop device of the gas leak of design angle control switch by ball valve and the combination of gas leakage electric opening/closing device.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: the electronic start-stop device of gas leak, comprise LPG (liquefied petroleum gas) valve and LPG (liquefied petroleum gas) valve controller, and the technical measures of taking comprise:
A. described LPG (liquefied petroleum gas) valve controller comprises motor, a valve closing snubber and a valve opening snubber is installed on the base plate that is covered with case, pass on the described motor output shaft of base plate a rocking arm with flange is housed, the flange of this rocking arm matches with described valve closing snubber and valve opening snubber, and the valve opening reset button that able to turn on or off motor is used is equipped with at the top of described case;
B. described LPG (liquefied petroleum gas) valve comprises the valve that is made of ball valve, and this valve is connected with motor with lower support frame and base plate by upper bracket; This valve has valve handle, and this valve handle can be inserted the recess of described rocking arm termination.
For optimizing technique scheme, the measure of being taked also comprises:
For guaranteeing reliably to be closed and opened by the valve that ball valve constitutes, the flange of above-mentioned rocking arm meets at right angles corresponding with the position that described valve closing snubber and valve opening snubber match.
Wide for making it adaptive scope, above-mentioned liquefaction air valve is liquified petroleum gas cylinder control valve or liquefied gas pipeline control valve, and described liquified petroleum gas cylinder control valve is by valve, and liquified petroleum gas cylinder set screw nut and valve handle are formed; For increase that the LPG (liquefied petroleum gas) valve controller installs firmly, be fastened on the bolt through butterfly nut by the upper bracket valve that is connected with lower support frame.
Compared with prior art, the utility model is a work characteristics in the angle according to the ball valve switch, realizes controlling motor and works in an angle of 90 degrees degree; By on the base plate of the installation of motor, a spacing control switch respectively being housed by axial 90 degree, and one flange is being arranged on the rocking arm that is connected with motor shaft, when motor is subjected to the out code of combustion gas autoalarm, motor drives valve handle by rocking arm and rotates in the direction of the clock, then switch and valve are closed simultaneously when the flange of rocking arm is run into spacing control switch, and motor also stops operating thereupon.And a valve opening reset button by being equipped with on the motor case, when after the gas leakage fault is excluded, needing again air feed, about 30 seconds of this button that need only press...with one's finger, the valve of closing is promptly performed fighting.The working procedure of opening is identical with closing, and different is that motor is rotated counterclockwise 90 degree.Thereby overcome because the valve that rotating force caused of motor and motor damage.It is simple to operate, and applicability is strong.
