Description
Technical field
The utility model relates to a kind of control gear of gas pipeline, particularly a kind of gas control valve.
Background technique
Gas valve is a kind of control valve for blocking, connecting, adjust the gas in pipeline, is applicable on the various gas such as town gas, liquid gas medium pipeline.
Traditional gas valve is primarily of valve body, valve body is arranged gas and enter pipeline and gas outflow conduit, gas enters between pipeline and gas outflow conduit and is provided with connection chamber, ball core is provided with in connection chamber, valve body is provided with and extends in connection chamber and the handle of the valve rod be connected with ball core and actuate valve stem, the flow of the rotation adjustable gas of ball core.
The foundation of gas pipeline facilitates the life of people, but can forget closing gas valve after use combustion gas of being everlasting during people, impels gas leakage, causes the situations such as poisoning.At present, the gas valve that market occurs only can solve the effect cut off or reconcile combustion gas, and how safer use gas control valve is then the current unsolved difficult problem in this field.
Summary of the invention
For prior art exist deficiency, the utility model provide when one does not use can automatically close, the simple gas control valve of structure.
For achieving the above object, the utility model provides following technological scheme: a kind of gas control valve, include valve body, valve body is provided with gas and enters pipeline and gas outflow conduit, gas enters between pipeline and gas outflow conduit and is provided with connection chamber, ball core is provided with in connection chamber, valve body is provided with and extends in connection chamber and the handle of the valve rod be connected with ball core and actuate valve stem, it is characterized in that: the gas of described valve body enter pipeline be provided with to enter with gas pipeline conducting detect gas port and with the installation cavity detecting gas port conducting, installation cavity relative to detect that the end place of gas port conducting one end is provided with drive motor, being provided with in installation cavity can with the Sealing detecting gas outlet seal, Sealing is provided with Compress Spring relative to the other end place detecting gas outlet seal one end, one end of this Compress Spring and Sealing are conflicted, the other end and drive motor are conflicted, Sealing be provided with towards drive motor extend compress bar, the startup switch of drive motor with compress pole pair and should arrange, the shut down switch of drive motor is located at the other end installing startup switch one end, and the motor shaft of drive motor extends in valve body and valve rod is connected.
Adopt technique scheme, when the non-normal combustion of combustion gas, namely user does not close gas control valve after using, combustion gas is in leak condition, combustion gas air pressure now in pipeline is greater than air pressure during fuel gas buring, air pressure overcomes the spring force of Compress Spring, by Sealing jack-up, Sealing compresses the startup switch that bar then can touch drive motor, drive motor is brought into operation, the valve rod linked with the motor shaft of drive motor then can impel ball core to close, and avoids combustion gas to continue to leak, for the use coal gas of people's safety or liquid gas provide guarantee.
The utility model is set to further: be arranged with turbine outside valve rod, and the motor shaft of drive motor is the scroll bar engaged with turbine.
Adopt technique scheme, it is simple that structure is set like this, easy for installation.
The utility model is further set to: Sealing is steel ball, and the installation place that valve body is positioned at drive motor is provided with fitting seat, and drive motor is installed on this fitting seat by fastening piece.
Adopt technique scheme, the installation being convenient to drive motor is set like this, also facilitate the maintenance to drive motor simultaneously.
Below in conjunction with accompanying drawing, the utility model is further described.
