Technical field
The utility model relates to a kind of for the fuel gas plug valve on gas range, relates in particular to a kind of fuel gas plug valve with mechanical type gear on-off.
Background technique
Generally comprise for the fuel gas plug valve of gas utensil to be provided with in the valve body, valve body that has gas-entered passageway and outlet passageway and have the spool of large fire hole and small fire hole and be located in the valve rod being connected on valve rod and with spool.The top of valve rod can be connected with the knob being arranged on stove panel, when use, operable knob and control handle bar, generally first press knob and rotate counterclockwise, can be with movable valve plug to rotate counterclockwise, fire hole on spool is connected with the gas-entered passageway in valve body, and source of the gas can pass through gas-entered passageway, outlet passageway and from nozzle ejection, for gas utensil.
The how many gas outputs of directly controlling combustion gas of angle of well-known valve rod rotation, the angle that is valve rod rotation is directly relevant with the gear of gas cooker, for learning whether valve rod rotates to big fire position or moderate heat position or little fire position, can only run through the corresponding indicating bit on kitchen range top face of pointer on the knob connecting with valve rod by eyes, and whether knob is rotated in place without any mechanical feel variation, whether the feel that knob band ovable valve stem rotates is poor, and be rotated in place without any feel or sound indication valve rod.
If a patent No. is the Chinese utility model patent " a kind of Gas cock valve assembly " of ZL200620140292.X (notification number is CN200982435Y), the patent No. is the Chinese utility model patent " fuel gas plug valve " of ZL201020181532.8 (notification number is CN201672087U), application number is the Chinese invention patent " Adjustable switch light a fire synchronous safe gas valve " of ZL201210159720.3 (publication number is CN102679000A), and the stopcock structure that their disclose has aforementioned drawback equally.Be that existing fuel gas plug valve does not all have band mechanical type gear on-off, gear deixis is short of to some extent.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of fuel gas plug valve with mechanical type gear on-off that has obvious feel and prompting sound after valve rod rotates to an angle for above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of fuel gas plug valve with mechanical type gear on-off, comprise valve casing and valve rod, it is characterized in that: also comprise the switch housing that relative valve casing is fixedly installed, and the switch core that is sleeved on described valve rod and can rotates with valve rod, described switch core is rounded, the lower end surface of described switch housing has cavity, switch core is positioned at cavity and can rotates relative to cavity, described valve rod movable upper end is through switch housing, in described switch housing or switch core, be provided with the steel ball being held by spring, this steel ball part exposes outside the inner circle wall of described cavity or the outer circumferential face of described switch core, the outer circumferential face of described switch core or the inner circle wall of cavity are provided with the draw-in groove that one or more and described steel ball matches, after valve rod rotates to an angle, described steel ball can be absorbed in corresponding draw-in groove, after valve rod continues to rotate to an angle, described steel ball can depart from again corresponding draw-in groove.
The above-mentioned steel ball being held by spring is arranged in switch housing, and described draw-in groove is arranged on the outer circumferential face of switch core.Because switch housing is positioned at the outside of switch core, switch housing exposes, and facilitate us that steel ball and spring is set in switch housing, and draw-in groove is easy to process, does not also affect assembling even if switch core is positioned at inside.
On the sidewall of above-mentioned switch housing, have the mounting hole radially running through, the exterior portion of mounting hole is tapped hole portion, the outer end opening of mounting hole is threaded connection the screw plug shutoff on mounting hole, and spring and steel ball are located in mounting hole, and spring top is held between screw plug and steel ball.This structure has assembling spring and steel ball advantage easily, after first switch housing and switch core being installed when assembling, successively from mounting hole outer end opening packs steel ball, spring into, finally block the outer end switch of mounting hole with screw plug again, whole assembling process completes.
Above-mentioned draw-in groove only has one, and only in the time of valve rod 90-degree rotation, described steel ball is absorbed in this draw-in groove.Certainly the number of draw-in groove can be set as required, can draw-in groove be set in needs gear prompting corresponding position.
The sidewall of above-mentioned switch housing has the extension part of evagination, and described mounting hole is arranged on this extension part.Without switch housing size entirety is done greatly, reduce space and occupy like this.
The sidewall of above-mentioned switch housing has two outward extending installation feet.
On the upper-end surface of above-mentioned valve casing, be fixed with support, described installation foot is fixed on this support by screw, and the bottom surface of described switch core is shelved on the upper-end surface of this support.Certainly also switch housing directly can be fixed on valve casing.
Compared with prior art, the utility model has the advantage of: on traditional mechanical type stopcock, increase mechanical type driving switch, in the time that valve rod rotates arrival precalculated position, steel ball enters draw-in groove under the effect of spring force, feel while realizing screens, to increase the travelling comfort of feel, in addition steel ball can send entering after draw-in groove " " prompt tone, prompting valve rod turns to the gear of corresponding gas valve.
