Abstract
The utility model provides a switch key adopting a two-level adjusting lever and a polyethylene gas valve thereof. The switch key comprises six components of the adjusting lever, a handle, screws, nuts, a key rod and a key bit, and is characterized in that the key rod and the key bit are welded together; the adjusting lever is inserted into the longitudinal hollow part of the key rod and can stretch and retract for realizing two-level adjustment; the screws penetrate through radial through holes in the adjusting lever and the key rod, the nuts are tightened and used for fixing the relative adjusting positions and transferring the torque, and the handle is inserted into the horizontal hollow part to form a T shape, so that the key bit can rotate under the action of external force, and opening and closing of the valve are realized.
Description
Technical field
The utility model relates to gas valve field, more specifically, relates to a kind of secondary adjustable lever switch key and polythene gas valve thereof.
Background technique
Buried polythene for traditional combustion gas (PE) valve, the length of switch key bar is uncontrollable, for the type that diffuses of different structure buried polythene (PE) valve for combustion gas, must be equipped with the switch key of different key bar length, the using scope of valve switch key is subject to narrow limitation.
Model utility content
The utility model provides buried polythene for a kind of combustion gas (PE) valve--secondary adjustable lever switch key, the length that is characterized in key bar can realize secondary adjusting, to adapt to the demand of the type that diffuses buried polythene (PE) valve for combustion gas of different structure, expand the using scope of switch key.
For realizing above object, the utility model provides a kind of secondary adjustable lever switch key, comprises adjustable lever, handle, screw, nut, key bar, key bit,
Described adjustable lever comprises that a horizontal cylinder hollow short tube and a vertical cylinder long tube connect into entirety, respectively has multiple through holes near the upper and lower end of cylinder stock, and its longitudinal section is T word shape,
Described handle is a cylinder long tube, and diameter is slightly less than the diameter of the horizontal cylinder hollow short tube of adjustable lever,
Described key bar is a vertical cylinder long tube, and lower end and key bit connect into entirety, respectively has multiple through holes near top and bottom, and its cross section is that the slightly larger in diameter of circular, described key bar is in the diameter of the vertical cylinder long tube of adjustable lever.
Described through hole is used for penetrating screw, and fixes by nut.
Described multiple through holes are 1 or 2 through holes.
Described key bit is that a vertical square short tube and a square metal plate are formed by connecting, and its longitudinal section is reverse U shape shape.
According to demand, then provide buried polythene gas valve for a kind of combustion gas, comprise an above-mentioned secondary adjustable lever switch key lock corresponding with key.
The utility model advantage is, the switch key that provides a kind of length to regulate can be realized the switch of the combustion gas that is embedded in the end, ground, and does not need to be equipped with the key bar of specific length.
