(1) technical field
The utility model relates to a kind of regulator of combustion gas, and especially a kind of switching type pressure regulator applicable to different combustion gas is as rock gas and liquefied petroleum gas.
(2) background technique
Make a kind of burner can be under the situation of different combustion gas all can proper functioning, must change the pressure of combustion gas.Existing regulator complex structure switches inconvenient.
(3) summary of the invention
The purpose of this utility model is to provide a kind of switching type pressure regulator of easy switching.
The purpose of this utility model is realized by following technological scheme.
A kind of switching type pressure regulator, comprise upper shell, bring lower shell body, diaphragm, press mold dish, mandrel, stage clip, valve seat, valve rod, the lever of gas port and air outlet into, it is characterized in that: be equipped with one on the upper shell and switch lid, switch in the lid and be provided with central shaft, the stage clip upper end is placed with platen, upper shell top is provided with through hole, the center hole that central shaft passes through hole and platen offsets, the through hole inboard is provided with stepped bayonet socket, be provided with claw in the switching lid, claw changes the upper-lower position that switches the relative upper shell of lid with the terrace corresponding matching of each different heights of bayonet socket.
The purpose of this utility model can also further realize by following technical measures.
The through hole inboard is provided with the bayonet socket of three circumference in equal parts, and each bayonet socket has the two-stage terrace and is the L type, switches to cover the claw that is provided with three circumference in equal parts.
Be provided with setting sleeve between claw and the central shaft.After switching lid insertion upper shell, refill setting sleeve, claw can't be sloped inwardly, make to switch and cover and can't from upper shell, transfer to.
Switch to cover and be provided with the Cock screw that can offset with upper shell.Surely will switch cover lock on upper shell at available this clamp screw after the switching.
A mounting disc is passed in the mandrel upper end, and mounting disc has and the corresponding rectangular hole of mandrel upper end section, and the both sides of rectangular hole are provided with recess, and the mandrel upper end may be stuck on the recess, is pressed with spring between mounting disc and the press mold dish.This structure is easy to assembly.
The utility model is simple and reasonable, switches easy to adjustly, easy to manufacture, and cost is low, practicality.

(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
See also shown in the accompanying drawing, a kind of switching type pressure regulator, comprise upper shell 1, bring the lower shell body 2 of gas port and air outlet into, diaphragm 3, press mold dish 4, mandrel 5, stage clip 6, valve seat 7, valve rod 8, lever 9, one switching is housed on the upper shell 1 covers 10, switch to cover and be provided with central shaft 11 in 10, stage clip 6 upper ends are placed with platen 12, upper shell 1 top is provided with through hole, the center hole that central shaft 11 passes through hole and platen 12 offsets, the through hole inboard is provided with the stepped bayonet socket 13 of three circumference in equal parts, each bayonet socket 13 has the two-stage terrace and is the L type, switch and cover the claw 14 that is provided with three circumference in equal parts in 10, claw 14 changes with the neither level terrace corresponding matching of bayonet socket 13 and switches the upper-lower position that covers 10 relative upper shells 1.In Fig. 1, claw 14 overhead kicks are on terrace down, and it is 10 lower that switching is covered, and the pressure of 6 pairs of diaphragms 3 of stage clip is bigger.In Fig. 4, on the terrace of claw 14 overhead kicks on, switch and cover 10 higherly, the pressure of 6 pairs of diaphragms 3 of stage clip is less.The rotation switching covers 10, can make claw 14 and different terrace cooperations.
Be provided with setting sleeve 15 between claw 14 and the central shaft 11.
A mounting disc 16 is passed in mandrel 5 upper ends, and mounting disc 16 has and the corresponding rectangular hole 17 of mandrel 5 upper end sections, and the both sides of rectangular hole 17 are provided with and recess 18, and mandrel 5 upper ends may be stuck on the recess 18, are pressed with spring 19 between mounting disc 16 and the press mold dish 4.
During use, combustion gas enters inner chamber through suction port, valve seat 7, and compressing diaphragm 3, after reaching setting pressure, the elastic force that diaphragm 3 overcomes stage clip 6 moves upward, and the mandrel 5 on the diaphragm 3 is upwards pulled lever 9, lever 9 is pushed valve rod 8 to valve seat 7 suction port is blocked up, combustion gas can't enter, when combustion gas under the head pressure of air outlet will after, diaphragm 3 borrows stage clip 6 to reset, mandrel 5 descends, lever 9 resets, and valve rod 8 also lifts off a seat 7, and combustion gas can enter again.As seen the pressure of combustion gas is subjected to the influence of stage clip 6 elastic force, cover 10 upper-lower position can regulate stage clips, 6 degrees of tightness and change to switch, i.e. elastic force size, thereby adjusting gaseous-pressure.
