17 and bar portion 18, one end, bar portion 18 is spacing by bounding means 19 through vent 15, bar portion 18 is at the other end outer casing spring 20 of vent 15, resetting-mechanism 21 is provided with outside steam outlet pipe 5, resetting-mechanism 21 matches with the bar portion 18 of security personnel's spool 16 through vent 15.Resetting-mechanism 21 comprises set casing 22, reset button 23, reset push rod 24, Returnning spring 25 and seal ring 26, the stepped one end of reset push rod 24 one-tenth is taper, reset push rod 24 overcoat Returnning spring 25 is arranged in the cavity of set casing 22 and reset button 23 formation, the end difference of reset push rod 24 arranges seal ring 26, and the tapered end of reset push rod 24 matches with the bar portion 18 through vent 15.In a state of use, the filter screen 27 at suction tude 4 place, for filtering from the impurity particle cylinder for liquefied gas high-pressure liquefaction gas out, avoids impurity to enter pressure governor inside.Rotate handwheel 28 pressure governor and cylinder for liquefied gas to be connected firmly, the liquefaction tracheae connecting kitchen range is connected on steam outlet pipe 5.Open angle value of liquefied gas cylinder to ventilate to leakproof safety type lpg regulator, liquefied gas stove is not when opening burning, pressure chamber 3 of the present invention is liquid gas abrim, rubber mass diaphragm 1 is in upwards heaving state with strength, top flat connecting rod 9 hauls push strut 10 upwards, the push strut 10 be articulated with in pressure chamber 3 is rotated, push strut 10 pushes toward the left side plug 11 of holding one's breath, make the rubber pad 29 of holding one's breath on plug 11 seal inlet hole 13 on air inlet nozzle 12 firmly, make pressure governor be pass gaseity.When leakproof safety type lpg regulator starts air feed to kitchen range, the amplitude that diaphragm 1 is upwards heaved can diminish, plug 11 of holding one's breath starts to be separated with inlet hole 13, liquid gas can flow into pressure chamber 3 through inlet hole 13 continuously, until diaphragm 1 heaves amplitude peak again, make the rubber pad 29 of holding one's breath on plug 11 again be close to inlet hole 13 and close source of the gas.If the liquefaction tracheae being connected to suddenly steam outlet pipe 5 comes off or breaks, the liquid gas in pressure chamber 3 will be caused to leak rapidly, due to the safe current-limiting effect of spool 16 of ensuring public security, the liquid gas on the left of security personnel's spool 16 is caused enough flowing on the right side of security personnel's spool 16 to supplement in time, this moment can produce pressure difference in security personnel spool 16 left and right sides,

voltage-regulation principle is the same (in the present invention introduces, the pressure regulation process of our just no longer enumeration pressure governor).Utilize pressure adjusting spring 8 can stretch voluntarily along with the liquid gas pressure change in pressure chamber 3, automatic control is held one's breath opening and closing thus controlling ventilate and pass gas of plug 11 and inlet hole 13, is automatically reduced pressure reposefully by the high-pressure liquefaction gas of coming in from suction tude 4 as the lower liquid gas of the air pressure that meets kitchen range safe combustion.The moment with gas is started at kitchen range, air pressure in pressure chamber 3 diminishes, diaphragm 1 is flat downwards, pressure adjusting spring 8 between top flat 6 and upper tegmental wall 7 can stretch downwards, top flat connecting rod 9 can move down, push strut 10 also can be press against and be moved down, plug 11 of holding one's breath draws toward the right, thus the plug 11 that makes to hold one's breath separates with inlet hole 13, liquid gas flows into pressure chamber 3, pressure governor automatically can separate the size of amplitude by hold one's breath plug 11 and inlet hole 13 of adjustment, makes to flow into the gas flow of pressure chamber 3 through air inlet nozzle 12 and to flow to the gas flow of kitchen range through steam outlet pipe 5 equal, reaches the transient equiliblium of tonifying Qi air feed.If kitchen range are stopped using, pressure chamber 3 air pressure can increase instantaneously, diaphragm 1 can be heaved again with strength, pressure adjusting spring 8 pressurized be pressed in above top flat 6 shrinks, top flat 6 and top flat connecting rod 9 all can rapidly on move, top flat connecting rod 9 hauls a push strut 10 and rises, and the plug 11 that makes to hold one's breath moves to left, until hold one's breath, the tight inlet hole 13 of plug 11 cuts off air vent prevention liquid gas and flows into pressure chamber 3, thus realizes closing gas.When the liquid gas flexible pipe being connected on steam outlet pipe 5 comes off or breaks, if the liquid gas that leaks flow exceed the security personnel flow of security personnel set by valve seat 14 time, security personnel's spool 16 will move to right and carry out security personnel pass gas.When the security personnel's flow flowed exceed set by security personnel's valve seat 14 that liquid gas leaks, under the metering function of security personnel's spool 16, the gas flow from flowing to steam outlet pipe 5 on the right of security personnel's spool 16 can be less than from security personnel spool 16 left side gas flow flowed on the right of security personnel's spool 16, cause producing an instantaneous pressure difference in security personnel spool 16 left and right sides, namely the air pressure on security personnel spool 16 left side is greater than the air pressure on the right of security personnel's spool 16, spring 20 now cannot bear the existence of this pressure difference, security personnel's spool 16 starts to move toward the right the airtight cut-out air-flow until the sealed department 17 of spool 16 of ensuring public security and the closed of security personnel's valve seat 14 are thoroughly fitted, to reset in the right-hand member in bar portion 18 of spool 16 and resetting-mechanism 21 distance of the conical surface of push rod 24 of now ensuring public security becomes very near.After eliminating gas leakage accident, only need press reset button 23, can the bar portion 18 of security personnel's spool 16 be pushed up toward the left side when reset push rod 24 moves down, the sealed department 17 of security personnel's spool 16 is separated with the closed of security personnel's valve seat 14, the liquid gas on such security personnel's spool 16 left side will flow to the right of security personnel's spool 16 at once, make the air pressure size of security personnel's spool 16 the right and left become identical, under the effect of spring 20, security personnel's spool 16 resets.Above-described embodiment is described the preferred implementation of leakproof safety type lpg regulator of the present invention; not the design of inventing and scope are limited; under the prerequisite not departing from the present invention
