The beneficial effects of the utility model are, adopted ball valve and on ball valve, offered the different pore in aperture, when ball valve rotates, by the flow of controlling natural gas that is communicated with of pores different on the ball valve with air admission hole and outer shroud pore, and then reaching syllogic flame, result of use is preferable.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is a cutaway view of the present utility model;

Fig. 2 is the schematic diagram of embodiment one of the present utility model;

Fig. 3 is the schematic diagram of embodiment two of the present utility model;

Fig. 4 is the schematic diagram of embodiment three of the present utility model.

The specific embodiment:

See accompanying drawing 1-4, the utility model comprises valve body 20, valve rod 10, is provided with central air chamber 21 in the valve body 20, and these central authorities' air chamber 21 peripheries are communicated with outer shroud pore 22, interior ring pore 23 and air admission hole 24 respectively, and valve body 20 also has igniting pore 25; Valve rod 10 front ends have ball valve 12, and ball valve 12 is positioned at central air chamber 21; Valve rod 10 centers are provided with centre bore 13, centre bore 13 is communicated with interior ring pore 23 at ball valve 12 ends, centre bore 13 other ends are communicated with pore 11 and pore 11 is communicated with igniting pore 25, offer three pores that are communicated with centre bore 13 on the ball valve 12, and three pores can be communicated with air admission hole 24, outer shroud pore 22 respectively during 12 rotations of this ball valve; Rotation valve rod 10 drives ball valves 12 and rotates synchronously, reaches the igniting of gas furnace and the control and regulation of flame size by the rotation of ball valve 12.

Three pores on the described ball valve 12 all are extended with air drain 17 at the spherical outside surface end.

The aperture of a pore is arranged less than two other in three pores offering on the described ball valve 12, three pores are respectively ball valve air admission hole 14, little pore 15, venthole 16, the aperture of wherein little pore 15 is less than ball valve air admission hole 14 and venthole 16, and three pores certain angle of being separated by respectively.

Described outer shroud pore 22 and air admission hole 24 are equipped with leakproof body 26 respectively with central air chamber 21 places of connection, and leakproof body 26 can be sealing ring, mainly are can not leak after making natural gas enter central air chamber 21; Between the leakproof body 26 of outer shroud pore 22 1 sides and central air chamber 21 inwalls spring 27 is housed, spring 27 is pushed leakproof body 26 ball valve 12 to and is kept both to fit tightly, and the connected state that makes natural gas comply with each pore flows; Air admission hole 24 1 sides be equipped with can be inconsistent with this side leakproof body 26 screw 28, the position by set screw 28 is with the adaptation between control leakproof body 26 and the ball valve 12.

It shown in the figure two schematic diagram that flame is the very hot oven state; The ball valve air admission hole 14 of one of three pores on the ball valve 12 is communicated with the blowhole 29 of leakproof body 26 at this moment, make natural gas enter the centre bore 13 of ball valve 12 through blowhole 29, ball valve air admission hole 14 by the air admission hole 24 of valve body 20, allow natural gas enter the outer shroud pore 22 of valve body 20 through pore 30 by venthole 16, reach by centre bore 13 and enter interior ring pore 23, simultaneously, natural gas is by pore 11 inlet point internal heat holes 25, and then reach the igniting and the function of inner and outer ring converter nose ignition combustion, this moment, the gas output maximum was the very hot oven situation.

It shown in the figure three schematic diagram that flame is the moderate heat state; This moment, ball valve 12 continued rotation by the figure two-state, venthole 16 separates with pore 30 and by ball valve 12 pore 30 is closed at this moment, the blocking-up natural gas enters outer shroud pore 22 again, allow the extinguishing of converter nose that outer shroud pore 22 is communicated with, and ball valve air admission hole 14 still keeps being communicated with blowhole 29, ring pore 23 in natural gas is still flowed to by centre bore 13, the converter nose flame that ring pore 23 is communicated with in allowing keeps burning, forms two sections moderate heat states.

Figure four is schematic diagrames that flame is little fiery state; This moment, ball valve 12 continued rotation by the figure three condition, and little pore 15 is communicated with blowhole 29, entered the flow of centre bore 13 with the minimizing natural gas, and the flame that makes the natural gas converter nose diminishes because of the flow reduction of natural gas.

In ball valve 12 rotation processes, air drain 17 all can be communicated with earlier with blowhole 29, pore 30, preceding hole is in reducing gas discharge in handshaking procedures to make each hole, and the hole that is connected later also increases gas discharge gradually, can make the converter nose flame of gas furnace be unlikely to extinguish.

Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, be not to limit the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
