The regulator 3 of this mode of execution comprises: lever 301, lever 301 is positioned at diaphragm chamber 6, and is fixing through pin 302, makes lever 301 to rotate along pin 302.Gasket seal 303 is located at an end of lever 301, is used to be sealed into gas port 304; Diaphragm axle 305 places the other end of lever 301; In this mode of execution, diaphragm axle 305 with the Placement of lever 301 is, has a joint 306 that diameter is less on the diaphragm axle 305, and diaphragm axle 305 is connected this joint 306 through through hole 315 with guide rail 307 on the lever 301, and links with lever 301.In addition, in other embodiments, also can connect the modes such as guide rail 307 of lever 301 through nut through attaching nut on diaphragm axle 305.Diaphragm axle 305 is provided with diaphragm 308, and diaphragm 308 is to be processed by elastic material, like HNBR, FPM etc.; The edge of diaphragm 308 is positioned at the joint that places valve gap 1 and valve body 2.Diaphragm 308 tops are provided with a diaphragm head 309, and diaphragm head 309 uses rigid material to process, like copper, aluminum alloy etc.; Diaphragm 308, diaphragm head 309 compress sealing and fixing with diaphragm axle 305 through nut 310.On valve gap 1, also be provided with a permanent magnet seat 311, between permanent magnet seat 311 and diaphragm head 309, place pressure adjusting spring 312.Permanent magnet seat 311 internal fixation one permanent magnet 313 is at diaphragm axle 305 internal fixation one irony object 314; In addition, also can be at permanent magnet seat 311 and diaphragm axle 305 inner fixing permanent magnets 313 respectively; Or, can be at permanent magnet seat 311 set inside irony objects 314, at diaphragm axle 305 set inside permanent magnets 313; Irony object 314 can be screw, iron block etc.In this mode of execution, permanent magnet 313 adopts the bonding mode of glue to fix with permanent magnet seat 314, in other embodiments, also can one projection be set in permanent magnet seat end, and restriction permanent magnet 313 moves to the direction that receives magnetic force.
The connection set 4 of this mode of execution comprises: be arranged on shell fragment 401 and pin 402 on the valve body 2, hook 403 is enclosed within on the pin 402, and an end is close to shell fragment 401, is used for clamping steel cylinder pipeline.Cutting off spool 404 can move up and down, and is used for the switch bottle gas.Valve pocket 405 is located on the valve body 2; Returnning spring 406 is arranged on and cuts off between spool 404 and the valve pocket 405, and cut-out spool 404 is used to reset; Seal ring 407,408 is located at and is cut off on spool 404 and the valve pocket 405; Play seal action; Be arranged on the seal ring 407 that cuts off on the spool when LPG begins, can seal pressure governor and steel cylinder pipeline, when LPG is closed; Can seal the gas in the pressure governor, play the double seal effect.Connect the folding that handle 409 is used to control LPG pressure regulator and steel cylinder pipeline.Connect handle 409 and have the safe self-locking mouth 410 that matches with switch knob 501, ensure that pressure governor opens under the state and can't separate with the steel cylinder pipeline at the gas liquefaction air to open, the assurance user's is safe in utilization.In addition, be appreciated that connecting handle 409 also can not have this safe self-locking mouth 410.In some other mode of execution of the utility model, can adopt other connection sets, for example shell fragment 401 is replaced with spring, at the steel cylinder pipeline junction one eccentric annulus is set, the cooperation through spring and eccentric annulus comes clamping steel cylinder pipeline.
The switch gear 5 of this mode of execution comprises: switch knob 501, switch knob 501 is tightly connected through seal ring 502 with valve body 2.Pad 503 is used for fixing switch knob 501, prevents that switch knob 501 from coming off from valve body 2; Cam 504 is located between said valve body 2 and the said cut-out spool 404, is used to back down cut off spool 404, makes the interior gas UNICOM of pressure governor and steel cylinder.
During use, the pipeline of liquefied petroleum ga steel cylinder is connected with connection set 4, through linking up with 403 because the elastic force effects of shell fragment 401, with pressure governor and the fastening of steel cylinder pipeline.The switch knob 501 of user's rotary switch device 5; Cam 504 will cut off spool 404 and eject; Gas and pressure governor conducting in the cylinder for liquefied gas, the safe self-locking mouth 410 that connects handle 409 is by switch knob 501 fastenings, at this moment; The steel cylinder pipeline can't break away from pressure governor, has ensured the Security in user's using process.
The high-pressure liquefaction petroleum gas is washed gasket seal 303 open; Get into diaphragm chamber 6 through suction port 304, along with increasing of diaphragm chamber 5 gases, diaphragm chamber 5 pressure raise; The elastic force that gas pressure intensity forces diaphragm 308 to overcome pressure adjusting spring 312 raises up; According to the character of magnet, the distance between the permanent magnet 313 reduces, and the magnetic force that receives promotes greatly.Make and move on diaphragm axle 305 drive levers 301 right-hand members rapidly that left end then presses down, and makes suction port 304 quick closedowns stop air feed, the pressure of diaphragm chamber 6 no longer rises.After opening gas stove switch, because combustion gas is outwards exported, diaphragm chamber 6 pressure diminish, and diaphragm 308 is recessed, and drive lever 301 right-hand members move down on the left end moving, and gasket seal 303 is opened, and high pressure petroleum gas gets into diaphragm chamber 6.In the combustion process of stove and accessory, diaphragm 308 ceaselessly epirelief is recessed, and gasket seal 303 is driven by lever 301, also along with constantly closing unlatching, has accomplished whole homeostasis process.The utility model has increased permanent magnet 313; Because the existence of magnetic force has changed the influence of the gas pressure of diaphragm chamber 6 to pressure adjusting spring 312, has accelerated the unlatching and the closing speed of gasket seal 303; Shorten the change-over period of whole transient equiliblium, thereby reduced the excursion of atmospheric pressure.It is good to have dynamic stability, and the response time is short, and is highly sensitive, the advantage that the outlet pressure fluctuating range is little.
When closing gas stove, pressure governor air outlet adapter 7 is closed, and the gas pressure of diaphragm chamber 6 rises, diaphragm 308 epireliefs, and under permanent magnet 313 effects, gasket seal 303 is closed rapidly, has guaranteed that the pressure in the pressure governor is lower than the standard of national CJ50-2008.
All documents in that the utility model is mentioned are all quoted as a reference in this application, are just quoted such as a reference separately as each piece document.Should be understood that in addition after having read the above-mentioned teachings of the utility model, those skilled in the art can do various changes or modification to the utility model, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
