Abstract
The utility model discloses a knob structure for a gas valve, comprising a knob body. A rotating shaft mounting hole is arranged on the knob body. The utility model is characterized in that a knob ring is positioned on the knob body, a hole for inserting the rotating shaft is arranged on the knob ring, and a positioning boss is arranged on the knob ring, and a positioning bar matched with the positioning boss is positioned on the knob body. When being used for two-gas sharing air valve, the utility model not only is convenient for switching of two gases by the user, but also prevents the gas channels from being closed due to the large rotating angle of the knob and avoids flame extinction on the gas stove.
Description
Technical field
The utility model relates to a kind of knob, particularly a kind of knob that is applied on the two gases shared gas valve.
Background technique
Gas range in use is installed in knob on the gas valve by rotation, drive the spool action of gas valve, thus the inlet hole on the change valve body and the coincidence factor of the inlet hole on the spool, the size of change blast tube, with the flow of adjusting combustion gas, and then reach the purpose of regulating the firepower size.Since at present the knob that adopts can only with the supporting use of gas valve of using single source of the gas, and can not adapt to the needs of two gases shared gas valve, therefore be necessary to develop a kind of knob for the two gases shared gas valve use.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of knob for the two gases shared gas valve use.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of gas valve knob structure, comprise the knob body, the knob body is provided with the rotating shaft mounting hole, it is characterized in that the knob body is provided with the knob ring, the knob ring is provided with the hole of interting for rotating shaft, the knob ring is provided with positioning boss, and described knob body is provided with the positioning bar that matches with positioning boss.
Preferred embodiment a kind of as the utility model, described positioning bar radially is arranged in the knob body.
The beneficial effects of the utility model are: the knob body is provided with the knob ring, the knob ring is provided with positioning boss, and the knob body is provided with the positioning bar that matches with positioning boss, in use, the knob ring is fixed on the gas valve, when knob during to several angle positioning bar contact with positioning boss, thereby the restriction knob is rotated further, like this when it is applied to two gases shared gas valve, both be convenient to the switching of user between two kinds of sources of the gas, can prevent also that the knob angle is excessive and make closing of blast tube, prevent the flame extinction on the gas range.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a sectional view of the present utility model;
Fig. 2 is the schematic perspective view of knob ring;
Fig. 3 is the schematic perspective view of knob.
Embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, the disclosed a kind of gas valve knob structure of the utility model, comprise knob body 1, knob body 1 is provided with rotating shaft mounting hole 2, knob body 1 is provided with knob ring 3, knob ring 3 is fixed on the valve body of gas valve in the using process by connecting plate, knob ring 3 is provided with the hole 4 of interting for rotating shaft, knob ring 3 is provided with positioning boss 5, and knob body 1 is provided with the positioning bar 6 that matches with positioning boss 5, positioning bar 6 radially is arranged in the knob body 1, in use, when knob during to several angle positioning bar contact with positioning boss, thereby the restriction knob is rotated further, and when it is applied to two gases shared gas valve, both has been convenient to the switching of user between two kinds of sources of the gas like this, can prevent also that the knob angle is excessive and make closing of blast tube, prevent the flame extinction on the gas range.
