Abstract
A changeover valve for gas sources structurally features that its flange plate seat is joined to wind-regulating plate valve on which there are concave circular recess and core valve for changing spray holes. Said core valve consists of circular core plate and screw handle. On said circular core plate there are two spray holes with different diameters and barrier block for regulating wind, which are matched with radically passing-through wind holes. An integral mixed gas chamber and tube are arranged outside the valve shell. Its advantages are simple structure, compact arrangement of parts, convenient operation and long service life.
Description
The present invention relates to the improvement of gas range, especially a kind of Changeove valve for gas source, it belongs to mankind life article's technical field.
Commercially available various gas range generally all are to use a kind of kitchen range of fuel gas source.Prior art has two kinds of fuel gas sources: a kind of is liquefied petroleum gas, and a kind of is the pipeline coal gas.These two kinds of fuel gas sources can not be connected on the gas range simultaneously, because two kinds of gas transmission nozzle mouth differences that fuel gas source is required, use a kind of kitchen range of fuel gas source suction valve of bore nozzle, and the burning of not competent two kinds of fuel gas sources needs.So just make troubles to use.Need can Sui Yi to use the kitchen range of two kinds of fuel gas sources in the real life.
The objective of the invention is to provide a kind of Changeove valve for gas source for table cooker tool use.For two kinds of fuel gas sources even three kinds, four kinds fuel gas sources, can turn on the air inlet valve body end of this valve respectively, random conversion source of the gas nozzle is as required just realized the effect of valve conversion source of the gas.
Task of the present invention has following technological scheme to finish, developed a kind of Changeove valve for gas source, it comprises: valve body, the flange panel seat that is threaded with this body cavity, this panel seat is by being inlaid in seal ring and the bolt on its end face, flange is connected with the air regulating board valve, the flange end face of this plate valve is provided with indent spherical cavity chamber and the movable conversion core valve that is inlaid in this chamber, cave, the flange end face of this plate valve is a plywood sleeve annular four-way valve housing, be provided with the air intake cylindrical void that radially connects on the chord shape housing of this valve chest, the axial outside disjunctor of this valve chest is connected with mixed air vessel's pipe.
Described conversion core valve, the conversion spray orifice eyelet eye that the core plectane of this core valve is provided with at least two pieces of different bores is positioned on the diameter line of this core plectane, and the place, pipeline axle center of the air regulating board valve that moves to valve body and flange and flange connection thereof can be changed in the center of all this eyelets; On this core plectane plate of the side of giving vent to anger of all this eyelets, be provided with the link stopper of regulating the air intake passage size that the air intake cylindrical void connects; This core plectane setting-in goes in the indent spherical cavity chamber and by one piece of bolt handle that passes the air intake cylindrical void to be fixed on the side cylndrical surface of this core plectane, thereby constitutes rotating conversion core valve.
Described air regulating board valve, the air intake cylindrical void on its plywood sleeve annular four-way valve housing are distributed on the arc shell of this valve chest on the chord shape housing, and wherein the shared central angle radian of the air intake cylindrical void on the arc shell is π-4/3 π; The shared central angle radian of air intake cylindrical void on the string shape housing is 1/5-1/6 π.
Described conversion spray orifice eye, it can evenly be arranged on this core plectane 2-4 piece, and this eyelet exists corresponding to the aperture of liquefied petroleum source of the gas: 0.6-1.60mm, this eyelet exists corresponding to the aperture of pipeline coal gas: 2.10-3.10mm.
Changeove valve for gas source advantage of the present invention is: owing to designed flange-type air regulating board valve, in this plate valve, be embedded with the conversion core valve that embeds in the indent spherical cavity chamber, and the conversion spray orifice eye of at least two pieces of different bores is set on the core plectane of this core valve, this eyelet can move to the place, pipeline axle center of air regulating board valve, constitutes from the unimpeded a kind of gas distribution channel of gas pipeline of a certain conversion spray orifice eye of valve body-flange panel seat-air regulating board valve.When the position of this core valve of conversion, just another can be changed the spray orifice eye and move the place, axle center that turns to gas distribution channel, constitute the unimpeded gas distribution channel of another kind of conversion spray orifice eye, realize the conversion of fuel gas source.This changing valve is simple in structure, only puts variation with the transposition of conversion spray orifice core valve, just can realize the source of the gas conversion, and it is reasonable in design, and sealing is tight, does not take up space again, and is easy to manufacture, easy to operate simple.As long as stir handle 180 degree change in location, the another kind of source of the gas of promptly replaceable use is realized the purpose that source of the gas is changed.
