Abstract
The utility model relates to a gas timing control valve. A casing body of the utility model is provided with a timing controller and a valve body inside, wherein the inner of the valve body is provided with a valve rod and a valve core plate integrally connected with the valve rod, and a main shaft of the timing controller is provided with a big gear. The big gear is meshed with a small gear on the upper end of the valve rod. The outer end of the main shaft of the timing controller which is extended outside the casing body is provided with a timing knob. The outer surface of the casing body is marked with a time indicating table. The utility model is matched with gas cookers, can extinguish gas cookers automatically at a definite time, can prevent fire and is safe.
Description
Technical field
The valving of using on a kind of gas pipeline is particularly with the matching used safety control valve of gas cooker.
Background technique
Use the family of gas ring, liquid gas cooking stove, natural gas range more and more now.All there is not self-closing device on the various gas range.Some people often because have a poor memory, tired sleeping or leave etc. former because of the accident green onion is busy thereby forgotten to close fire, cause kitchen range to burn for a long time, be easy to cause the gas pipeline burning, cause serious fire, even cause human casualty accident.
Summary of the invention
The purpose of this utility model provides a kind of combustion gas timing control valve, accomplishes that timing automatic closes, and guarantees the safe handling of gas range.
Technological scheme is that electric fan type timing controller and valve body are housed in the housing, the valve body import connects compressed air source unit, outlet connects gas cooker, the valve core plate that valve rod is arranged in the valve body and combine as a whole with valve rod, on electric fan type timing controller main shaft, gearwheel is installed, the pinion of gearwheel and valve rod upper end, main shaft are stretched out on the outer end of housing regularly knob are housed, and housing outer surface is marked with the time index gauge.
Working principle is as follows: control valve is closed at ordinary times.When needs use gas cooker, knob on the timing controller at first turns clockwise, set the time that needs burning, with it simultaneously, knob simultaneously makes spring screw, one side makes the deflection of timing controller main shaft, and counterclockwise deflection makes the valve core plate of control valve deflect into open mode by the large gear turn the small gear.In combustion process, the deflection counterclockwise of the knob automatic slowly ground on the timing controller.When knob at the set time intrinsic deflection when the zero-bit, the escapement action of timing controller, main shaft is deflection counterclockwise under the effect of spring, the clockwise deflection by the large gear turn the small gear, make the valve core plate of control valve deflect into closed condition, reach the purpose of auto extinguishing.
Compared with the prior art, characteristics of the present utility model are that timing automatic is extinguished gas cooker, and fire preventing is safe and reliable.
