Abstract
The utility model discloses a cock valve for a household gas cooker. The cock valve comprises a valve body, a valve core and a valve rod, wherein a fixing plate which is used for fixing the valve rodand penetrates through the valve rod is arranged on the valve body, and a lining board, a thumb wheel and a cover board which are sleeved on the valve rod in a laminated and penetrating manner is arranged on the fixing plate; the lining board is fixed on the fixing plate, arc-shaped positioning holes are formed on the periphery, and each positioning hole comprises two parts, namely a reaming areaand a hole narrowing area; positioning rods penetrating into the positioning holes are arranged on the bottom surface of the thumb wheel, a strip-shaped through hole for the penetrating of a valve rodis arranged in the center of the thumb wheel; slide openings embedded with steel balls are arranged adjacent to the strip-shaped through hole; the cover board is fixed on the lining board to press the thumb wheel and the steel balls; and two spacing holes matched with the steel balls are arranged on the cover board. Since the steel balls are embedded in the two spacing holes on the cover board, the cock valve can easily realize the minimum gas quantity adjustment of the inner and outer rings of the valve and the accurate zero confirmation; and at the same time, since the cover board is an elastic thin sheet, when the steel balls are embedded in the spacing holes, a ringing sound is generated, thereby having sound prompting function.
Description
Technical field
The utility model relates to a kind of stopcock, relates in particular to a kind of household gas range stopcock.
Background technique
Existing household gas utensils stopcock has all been set up virgin lock and limit function in some positions of often using, and the spacing functions of child lock, 90 that closes fiery position as 0 degree is spent the limit function of big fire position and 170 degree inner rings fire for protecting the limit function of fiery position.
Present stage; the equal mandatory requirement of domestic kitchen range increases flame-out protection device; after increasing this device; use in the kitchen range process; when inner ring fire and outer ring fire all being transferred to hour (this position also is the higher position of frequency of utilization); because of there not being the limit structure of this position on the existing stopcock valve body; often can't accurately adjust to this firepower; so when regulating this position; often make that inside and outside ring tolerance is too little in the stopcock, flame-out protection device extinguishes fire, even it is inoperative flame-out protection device to occur; the phenomenon (because air and gaseous-pressure imbalance cause combustion gas to be burnt at valve inner) that tempering occurs.
Existing stopcock generally all is provided with limit stoper in 0 degree closed position, realizes that but generally close by reversing knob long service time when stopcock, knob can become flexible, and can't judge accurately that by naked eyes whether valve closes fully, exists potential safety hazard.

Embodiment
As shown in the figure, a kind of household gas range stopcock, comprise valve body 1, spool 8 and valve rod 3, spool 1 is provided with outer shroud air outlet 81 and interior ring air outlet 82, valve body 1 inside is provided with suction port, outer shroud air outlet hole 11 and interior ring air outlet hole 12, outer wall is provided with fixed plate 4, and fixed plate 4 is set on the valve rod 3, and valve rod 3 is vertically fixing.
Also be provided with 3 liner plates 5, thumb wheel 6 and the cover plate 7 that are set in equally on the valve rod on the fixed plate 4, liner plate 5 is fixed on the plate 4, and periphery has the positioning hole 51 of an arc, and positioning hole 51 is made up of reaming district 52 and narrow porose area 53 two-part.
The center of thumb wheel 6 has the bar hole 61 that passes for valve rod 3, bar hole 61 is rectangular preferably, can certainly select other shape, but must guarantee that the both sides inwall of its length direction is parallel, make thumb wheel 6 relatively valve rod 3 slide along bar hole 61 length directions, two planes that are parallel to each other are correspondingly arranged on the valve rod 3, and these two planes are pasted mutually with two inwalls of bar hole 61 length directions and are touched.
Certainly driving lever 3 also can have only the side inwall subsides of a plane and bar hole 61 length directions to touch, the opposite side inwall of bar hole 62 length directions and the circumferential surface of valve rod 3 paste and touch, when guaranteeing that valve rod 3 drives thumb wheel 6 rotations, can slide along bar hole 61 length directions in thumb wheel 6 rotation processes.
When valve closing, positioning rod 62 is arranged in an end of the narrow relatively porose area 53 in reaming district 52, and steel ball 63 is embedded in first spacing hole 71.Behind the Open valve, valve rod 3 drives thumb wheel 6 and rotates, positioning rod 62 also slides in positioning hole 51 thereupon, an end of narrow relatively porose area 53 slides to the intersection of reaming district 52 and narrow porose area 53 from reaming district 52, positioning rod 62 moves along the edge, outer ring 54 in reaming district 52, whole process valve rod 3 just revolves and turn 90 degrees, the overlapping radian maximum of outer shroud air outlet hole 11 and outer shroud air outlet 82, the overlapping radian maximum of interior ring air outlet hole 12 and interior ring air outlet 82, when promptly ventilating, maximum gas output appears in interior ring air outlet hole, outer shroud air outlet hole.Certainly the position of the intersection of reaming district 52 and narrow porose area 53 can be adjusted, and makes when positioning rod 62 slides to this position, and the angle of valve rod 3 rotations is greater than or less than 90 degree.
Because the intersection of reaming district 52 and narrow porose area 53 is narrow spaces, slide to an end of relative narrow porose area 53 the reaming district 52 from the intersection of reaming district 52 and narrow porose area 53,52 inner ring edges 55 move positioning rod 62 along the reaming district, when valve rod 3 rotations 45 are spent, steel ball 63 imbeds in second spacing hole 72, this moment, outer shroud air outlet hole 11 was 7 degree with the overlapping radian of outer shroud air outlet 81, and the overlapping radian of interior ring air outlet hole 12 and interior ring air outlet 82 is 5 degree, the Throughput minimum of ring air outlet hole 12 and outer shroud air outlet hole 11 in this moment.Can certainly correspondingly adjust the radian size, generally the overlapping radian with outer shroud air outlet hole 11 and outer shroud air outlet 81 is arranged on 6～8 degree, and the overlapping radian of interior ring air outlet hole 12 and interior ring air outlet 82 is set to 4～6 degree.
When positioning rod 62 slides in the narrow porose area 53 of positioning hole 61, when valve rod revolved 145 when spending from initial position, steel ball 63 embeds in the 3rd spacing hole 73, as shown in figure 15, the overlapping radian of outer shroud air outlet hole 11 and outer shroud air outlet 81 is 0 degree, and the overlapping radian of interior ring air outlet hole 12 and interior ring air outlet 82 is 14 degree.Ring air outlet hole 12 Throughputs are bigger in this moment, and the stuffiness of outer shroud air outlet hole.
When positioning rod 62 slides into the other end from positioning hole 61 1 ends, valve rod 3 has just rotated 175 degree, and the internal heat amount appears protecting in valve, and when position, the fire air outlet of the guarantor on the spool 2 changed, the angle of swing of valve rod 3 also changed thereupon.
