Description

The motor switch valve of combustion gas intelligence controlling device

The utility model relates to the control gear of gas pipeline opening and closing, is specifically related to be used in the resident living motor switch valve of fuel gas pipeline control gear.

Combustion gas (as the coal gas) metering and the toll administration that use in the urban and rural households life, normally by being connected in the IC-card pattern gas meter control gear in user's indoor fuel gas pipeline, automatically realize the unlatching of user's gas pipeline or close, to realize that civil gas management department buys gas consumption in advance to the resident, the quantitatively monitoring management of timing in use.Said control gear generally is by being connected in the straight line motion of the bistable electromagnetic switch valve on the fuel gas pipeline, realizes the unlatching of fuel gas pipeline or closes.Exist not enough: the one, electromagnetic switch valve uses reliability and stability poor.The user in use, because of fuel gas pipeline is subjected to vibrations (maintenance is collided as fuel gas pipeline), easily make control gear out of control, often cause the user to purchase gas consumption in advance and do not use up and close the gas valve phenomenon too early, had a strong impact on Consumer user's (buying gas side) economic benefits; The 2nd, electromagnetic switch valve uses for a long time, its valve body connected element is connected and is prone to adhesion phenomenon, when purchasing gas consumption in advance, the resident uses up, when needing to close gas valve by control gear immediately, but can not promptly and accurately move and close, but cause still use without compensation combustion gas of resident, grievous injury the economic benefits of civil gas management department (selling gas side).

The purpose of this utility model is; Provide a kind of use reliable and stable, move accurately nimblely, safeguard that effectively Consumer user and civil gas management department use and manage the motor switch valve of the combustion gas intelligence controlling device of combustion gas common interests.

The technical solution of the utility model is achieved in that the motor switch valve of this combustion gas intelligence controlling device; Mainly comprise: valve gap one end is connected with motor; The valve gap the other end is connected with valve body; The valve body outer end is connected with seal rubber pad and rubbery membrana dermalis by the locking pull bar respectively; Its improvement is: described locking pull bar one end places the spigot nut mesopore in the valve hole guiding groove to be connected with slip; Slide in the locking pull bar mesopore and be equipped with guide sleeve and spring; The magnet ring that body cavity end end face is provided with is corresponding in the same way with magnet ring on placing its inner chamber spigot nut end face; One end rotates the drive screw on the inner chamber end that is connected in valve gap and valve body, is fixed with reduction gear on its cylindrical and is meshed with the motor gear that places the valve gap inner chamber; Run through the drive screw the other end cylindrical that places body cavity and be provided with screw thread, and be provided with spigot nut that the inner hole thread position is corresponding to be in state to be connected; Intermediate portion at described drive screw cylindrical is provided with clearance groov.

The utility model is taked said structure, different rotation directions by the driven by motor drive screw are rotated, realized driving the seal rubber pad shift reciprocately with the spigot nut of its screw-thread fit, controlled the unlatching of gas valve respectively or closed, use reliable and stable, move accurately nimblely, safeguarded the common interests that Consumer user and civil gas management department used and managed combustion gas effectively.

Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
