Embodiment
As shown in the figure, a kind of step-less adjustment stopcock, comprise valve body 1, valve body 1 is provided with suction port and steam outlet pipe 102, steam outlet pipe 103, the suction port place is equipped with solenoid valve 3, be provided with faucet hole 101 in the valve body 1, establish the spool 2 that cooperates with it in the faucet hole 101, spool 2 relies on the motor 4 that is installed on the valve body 1 to drive.
First group of air outlet hole is made up of the maximum air outlet hole 211 of outer shroud, outer shroud stage casing air outlet hole 212 and the minimum air outlet hole 213 of outer shroud, second group of air outlet hole is made up of maximum air outlet hole 221 of interior ring and the minimum air outlet hole 222 of interior ring, simultaneously be provided with the interior ring vent slot 223 that is communicated with the maximum air outlet hole 221 of interior ring at the first spool outer circumferential face that goes to be provided with 214, the second groups of air outlet hole places of the outer shroud vent slot height that is communicated with the maximum air outlet hole 211 of outer shroud on the spool outer circumferential face of air outlet hole place height.Two vent slots are all put along the winding of spool circumferential hoop.
Outer shroud stage casing air outlet hole 212, the minimum air outlet hole 213 of outer shroud and the minimum air outlet hole 222 of interior ring radially dwindle near the part of center hole and form control gas section 215, control gas section 216 and control gas section 224.The pore size of control gas section has determined the firepower of the little fire of kitchen range outer shroud, outer shroud moderate heat and the little fire of interior ring.
Shown in Fig. 6～12, during 0 ° of valve core rotation, inlet hole 111 and inlet hole 112 all do not have gas and flow into, and the kitchen range inside and outside ring does not all have fire.
During valve core rotation to 22 °, the minimum air outlet hole 222 of interior ring just is communicated with inlet hole 112, when turning to 55 °, then both centers over against, when turning to 67 °, interior ring vent slot 223 beginnings are communicated with inlet hole 112, inlet hole 112 interior throughputs can be regulated at this moment; When turning to 88 °, the minimum air outlet hole 222 of interior ring leaves inlet hole 112.
During valve core rotation to 100 °, throughputs reach maximum in the inlet hole 112, and when turning to 103 °, minimum air outlet hole 213 beginnings of outer shroud are communicated with inlet hole 111.
During valve core rotation to 145 °, minimum air outlet hole 213 beginnings of outer shroud and inlet hole 111 over against.Turn to 154 when spending, air outlet hole 212 beginnings in outer shroud stage casing are communicated with inlet hole 111, turn to 190 degree, outer shroud stage casing air outlet hole 212 begin and inlet hole 111 over against.
During valve core rotation to 198 °, 214 beginnings of outer shroud vent slot are communicated with inlet hole 111, and the throughput that begins inlet hole at this moment can be regulated.When turning to 295 °, throughput reaches maximum value in the inlet hole 111.
Therefore, in the angle of about 55 ° of valve core rotation, inlet hole 112 air inflows are stable, remain the minimum air flow amount.In the angle of about 145 ° of rotations, inlet hole 111 air inflows are stable, remain the minimum air flow amount, in the angle of about 90 ° of rotations, inlet hole 111 remains the stage casing throughput, inlet hole 112 air inflows just can be regulated from valve core rotation to 67 ° beginning, and the air inflow of inlet hole 111 can be regulated from valve core rotation to 198 ° beginning, maximum airflow appears simultaneously until turning to 295 °, with this valve applications to kitchen range, can accurately control little fire, moderate heat and the big fire of inside and outside ring, and the big fire firepower can step-less adjustment.
