Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technological scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
A kind of gas conversion valve with double air sources device as shown in Figure 1, Figure 2 and Figure 3, comprise rectangular-shaped valve body 1, the inlet hole 2 supplying dual gas supply turnover and the air outlet hole 4 with seamed edge, dual gas supply is rock gas and liquid gas, also comprising the handled spool 3, first of band regulates plug 7 and second to regulate plug 8, spool 3 is pre-small post-large, and front end is coniform, and back segment is cylindric, valve body 1 one end is provided with the spool bore matched with spool 3, and the other end is provided with air outlet hole 4; Inlet hole 2 is positioned on valve body 1 sidewall, vertical with air outlet hole 4 through; Air vent 5 is provided with, as shown in Figure 4 between inlet hole 2 and air outlet hole 4.This air vent 5 is provided with 4 vents, vent one of them be positioned at air vent 5 circle centre position, all the other are along the equal portion of air vent 5 circumference.Spool 3 is successively through spool bore and inlet hole 2, and its front end extend in a vent in the middle of air vent 5; Valve body 1 is respectively equipped with two adjustment holes connected with air vent 5, first regulates plug 7 and second to regulate plug 8 to be arranged in corresponding adjustment hole.Also comprise anti-skidding fixing pin 6, described valve body 1 sidewall is provided with the perpendicular through fixed hole with spool bore, spool 3 is provided with successively two draw-in grooves side by side, and anti-skidding fixing pin 6 is embedded in draw-in groove through fixed hole, for fixed spool 3, effectively prevents it from exiting.Inlet hole 2 is measure-alike and can mutually replace with air outlet hole 4.Valve body 1 is provided with mark 9 and the operational instruction of combustion gas switching.As shown in Figure 5.Mark 9 is NG/LP and switches arrow, i.e. rock gas/liquid gas.Valve body 1 is plunger type valve body.
Working procedure of the present invention is: hold spool 3 handle mobile position, control the cross-section that main suction tude is different, produce different fuel air inlet total amount, determine air inlet metering-orifice needed for rock gas and liquid gas, plug 8 is meticulous adjusts tolerance to regulate plug 7, second to regulate by 2 fine setting plugs first, its Adjustment precision is high, reaches the requirement of different product tolerance.When only need change fuel when user uses, by spool 3 push-and-pull to corresponding NG/LP position, i.e. rock gas/liquid gas, concrete user only need pull out spool 3, the passage of spool 3 front end in the middle of air vent 5 shifts out, the vent that centre is plugged exposes, and increases a vent and makes inlet hole 2 cross-section become large, meet rock gas gas and use.Spool 3 is pushed back reset by user, and the passage in the middle of air vent 5 is stretched in spool 3 front end, blocks middle vent, namely reduces by a vent and inlet hole 2 cross-section is diminished, and labour meets liquefied petroleum gas (LPG) and uses, and operator is convenient and swift.This invention also has another specific function, and after production debugging completes, inlet hole 2 and air outlet hole 4 can exchange, and greatly facilitate the use of user.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
