Description

The automatic pressure control device of fuel oil-gas

The utility model relates to gas furnace, especially refers to a kind of pressure control device of gas furnace.

Existing gas furnace and pressure control device thereof, the burning gases that it adapted to as blast furnace gas, liquefied gas, producer gas, also have rock gas etc. mostly for coal gas, and these gases all have enough combustion pressures no matter be bottled or pipeline transportation.In addition, but a kind of lightweight oil plant is arranged, the blue or green seed oil that promptly is commonly called as, the inflammable gas that it produced, because of pressure is too low, can not adapt to general family gas stove sustained combustion, also promptly existing gas stove pressure control device can not adapt to the inflammable gas of the lower pressure that this lightweight oil plant produced.

The purpose of this utility model provides a kind of automatic pressure control device that adapts to the fuel oil-gas of the lower pressure that light fuel produces.

The purpose of this utility model is achieved in that the automatic pressure control device of fuel oil-gas, it comprises controller, coal gas adjuster and pneumatic pump controller are located in the coal gas adjuster, the coal gas adjuster comprises body and lid, and the seal casinghousing of hollow form is formed in the locking of mat screw, body one termination cylinder joint, termination gas stove joint in addition, body interior forms an oil-gas room and communicates with cylinder joint and gas chamber joint, it is characterized in that, set firmly a holder in the lid, the holder top is fixed with two contact chips, this two contact chip each with the external pneumatic pump of lead and leave spacing, the pneumatic pump power supply is open circuit; The holder activity sets a control piece, and a guide-joining plate is fixed in the control piece upper end, and the lower end connects a sleeve, establishes a spring between sleeve and holder, and the coal gas adjuster has the interlock post, and its upper end is matched with in the sleeve, and this spring upper end connects control piece, lower end coupling sleeve.

Above-mentioned design, but mat spring pushing tow sleeve to bottom offset, makes the guide-joining plate of control piece upper end contact two contact chips with the pulling control piece to bottom offset, makes the power supply of pneumatic pump be a loop; Pneumatic pump has the tracheae tipping that the steel cylinder of soft oil plant is arranged, and pneumatic pump can move automatically according to the steel cylinder internal pressure and inflate into steel cylinder, makes oil accelerate volatilization, reaches the effect that satisfies gas stove combustion requirements pressure.

Below by drawings and Examples the utility model is described further again:

Fig. 1 is the three-dimensional combination of a utility model synoptic diagram;

Fig. 2 is the utility model body decomposing schematic representation;

Fig. 3 is the utility model main body cross-sectional schematic;

Fig. 4 is the utility model user mode synoptic diagram;

As Figure 1-3, existing coal gas adjuster 11 includes a body 12 and a lid 13, but the seal casinghousing of hollow form is formed in a plurality of screw 26 lockings of body 12 and lid 13 mats, body 12 1 ends are established a steel and joint 14, the other end is established a gas stove joint 15, the body 12 inner oil-gas room 16 and steel and joint 14 that form, gas stove joint 15 ventilation of joining, 13 of body 12 and lids insert and put the valve block 17 that materials such as a rubber are made, mat valve block 17 separates body 12 and lid 13 volume inside, valve block 17 centers cooperate an interlock post 18, interlock post 18 is formed with a ring flange 21, the interlock post 18 movable intermediate plates 19 that cooperate, 19 of interlock post 18 upper ends and intermediate plates are established a spring 20, spring 20 pushing tow intermediate plates 19 are to bottom offset, make valve block 17 elasticity be folded in 21 of intermediate plate 19 and flanges, oil-gas room 16 is pivoted with a pivot 22 and one stops bar 23, fork 23 1 ends are arranged in interlock post 18 lower ends, fork 23 other ends are established an air shuttle valve 24,16 of steel and joint 14 and oil-gas room establish an air intake opening 25, the air shuttle valve 24 of fork 23 1 ends is positioned at air intake opening 25 tops, valve block 17 can be done along with the air inlet of steel and joint 14, under agitate, do with interlock interlock post 18, bottom offset, interlock post 18 can drive fork 23 and swing, block or open air intake opening 25 with air shuttle valve 24, because of above-mentioned adjuster 11 structures belong to known technology, so no longer given unnecessary details.The utility model is mainly established a holder 27 in lid 13 upper ends of coal gas adjuster 11, two contact chips 28 are fixed with screw 36 nuts 37 in holder 27 tops, this two contact chip 28 respectively respectively convexes with contact point 38 with lead 29 an external pneumatic pump 30, two contact chips 28 inner edges.28 of two contact chips have suitable spacing, so that the power supply of pneumatic pump 30 is an open circuit, holder 27 central movable cooperate a control piece 31, control piece 31 upper ends cooperate a guide-joining plate 32, and screw togather a nut 33 with guide-joining plate 32 lockings, a coupling sleeve 34 is fixed in control piece 31 lower ends, and interlock post 18 upper ends are matched with in the sleeve 34, and is provided with a spring 35 in sleeve 34 and 27 of holders; Lid 13 upper end snails unification end cap 39 in coal gas adjuster 11 is sealed in addition.

As shown in Figure 4: work as energized, make pneumatic pump 30 starts, inflate, make light fuel 43 volatilizations in the steel cylinder 40 fast, for the combustion gas of giving gas stove 41 enough pressure into steel cylinder 40.When pressure is increased to when filling part the degree of setting, then the combustion gas in the oil-gas room 16 promptly can promote valve block 17 and upwards agitate, promote sleeve 34, control piece 31 to top offset with interlock post 18, make guide-joining plate 32 break away from two contact chips 38, so that the power supply of pneumatic pump 30 is an open circuit, make pneumatic pump 30 controlled device 10 controls outages automatically, stop to inflate this shows, the utlity model has reliable safety assurance into steel cylinder 40, and it is very practical, easy to use.
