Abstract
An energy-saving type flow control valve for hybrid gas comprises a gas inlet pipe (1), a gas outlet pipe (9), a valve body (2), a valve core (3), a valve stem (4) and a valve cover (8), wherein, the lower part of the valve core (3) which is in the same plane with the central positions of the gas inlet pipe and the gas outlet pipe is provided with a via hole (10) and a reaming (12) of the via hole (10); an free-end of the valve stem (4) is connected with a knob (6); the valve cover (8) is provided with a block component (5); gaskets (7) are arranged between the valve cover (8) and the valve stem (4) and between the valve cover (8) and the valve body (2). The utility model can be arranged in a hybrid gas pipe or a gas chamber which is not convenient for closing and a gas flow and an oxygen flow are required to be respectively regulated, such as in a welding and cutting process of torque welding and cutting, an exhausting and sealing process of an energy saving lamp, a strong fire and constant burning is changed into a situation that strong or weak fire can be regulated according to requirements and the constant burning can be adjusted. The utility model has the advantages of simple structure, low manufacture cost and obvious energy-saving effect.
Description
Technical field
The utility model relates to the combination gas flow control valve after a kind of Remarkable Energy Saving inflammable gas and the oxygen mix.
Background technique
Welding torch, cutting torch are when using, need acetylene gas and oxygen are adjusted to suitable flow respectively, the use when size of flame is met the requirements is during use, if the mobile position of operator own, or workpiece moves the position, or operator and other people exchange views temporarily uniformly-spaced that property delays, and often can not close and knock down the flame, let alone burning, because, light once more and need regulate respectively acetylene and oxygen again, feel time-consuming and trouble in case put out.The acetylene gas of so lighting in vain in 1 year is surprising.
The situation of waste combustion gas also is like this in the deairing step of Compact Fluorescent Lamp, is earlier coal gas (natural gas) and oxygen to be adjusted to desired flow respectively equally, and flame size is suitable, again to glass lamp dress tungsten filament, vacuumize, glass-tube seals.In this operation, the dress tungsten filament accounts for 80% with time of vacuumizing, and the time of sealing accounts for 20%, that is to say that the effective rate of utilization of the mixed gas after coal gas (natural gas) and the oxygen mix only has an appointment 20%, and all the other times are regulated to mistake because of need and let alone combustion.At present, domestic Compact Fluorescent Lamp industry ubiquity the phenomenon of low-price competition, and combustion gas but exists great waste, and still unmanned motive therebetween.CN2703638Y has announced " Gas controller of full-automatic plastic bottle blowing machine " patented technology, CN2553250Y has announced " Gas controller " patented technology of using steel-making, refining casting system, the structure more complicated, cost of production is higher, very is not fit to application of the present utility model.
Summary of the invention
The purpose of this utility model be at the time of worry regulating in the mixture combustion of some production fields too much and the loss that the long combustion of very hot oven causes, provide a kind of simple in structure, cost is low, as required can be prosperous can be secretly, needn't regulate the energy-saving combination gas flow control valve of combustion gas and oxygen flow more respectively.
The purpose of this utility model can realize by following measure: this energy-saving combination gas flow control valve, include suction tude, steam outlet pipe, valve body, spool, valve rod, valve gap, spool bottom and suction tude, steam outlet pipe central part are in place, same plane and have the through hole that penetrates spool, and the reaming in this hole, the valve rod free-end is connected with knob, knob stop bit spare is arranged on the valve gap, between valve gap and the valve rod and between valve gap and the valve body sealing gasket is arranged.
The purpose of this utility model can also be come perfect by following measure: the internal diameter of valve body is than the big 0.2-0.4mm of external diameter of spool.The spool ring that at least two spool grooves and coupling are arranged on the spool.Said stop bit spare is rod-type stop rod or cylinder type stop bit point.Said reaming side is other to be extended with from deep to shallow, by wide to narrow groove.
The beneficial effects of the utility model are that simple in structure, fabricating cost is economized, and both may command intensity of a fire sizes does not need to readjust respectively the flow of combustible gas and oxygen again again, change the long combustion of very hot oven and fire obvious energy conservation for dark prosperous adjustable length as required.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
The utility model is described in further detail below in conjunction with embodiment and with reference to accompanying drawing: this control valve is fit to be installed in mixed mixed combustible gas pipe, air chamber.After becoming suitable ratio with oxygen mix as inflammable gass such as acetylene gas, rock gas, coal gas, flow in the through hole 10 by suction tude 1, arrive duration and degree of heating through steam outlet pipe 9 again, igniting welding or seal, if through hole 10 is accurate suction tude 1 and steam outlet pipes 9 of facing toward, then gas maximum, fire are the most prosperous, and knob 6 is also just in time touched cylinder type stop bit point 5.If will turn the intensity of a fire down, turn knob 6 counter-rotatings, the through hole 10 of former aligning tracheae 1,9 is left gradually, when not breaking away from fully as yet, when the edge of only remaining reaming 12 or groove 11 and tracheae 1,9 are close to slightly, the flow minimum of combination gas, fire are the darkest, and knob 6 is also just in time touched on another cylinder type stop bit point 5.Knob is between 2 stop bit points the time, and the intensity of a fire is medium.Knob is screwed to a side and ends site when needing very hot oven, needs dying fire to be screwed to opposite side and ends site, needn't regulate combustible gas and oxygen flow more again respectively, and is very quick.So turn knob, reach the purpose of the control combination gas flow and the intensity of a fire.For reducing the dispersion of air-flow, the gap of spool 3 outer walls and valve body 2 inwalls is little during making, conveniently is principle to disperse gas less and to rotate, and also can solve in order to the mode that spool (piston) ring is installed.Knob 6 also can be used handle type instead, and stop bit spare 5 can be the rod-type stop rod.Through hole 10 can be only with reaming 12 modes, then require to strengthen the bell-mouthed diameter of reaming, that preferred version is that the one or both sides of reaming 12 have is extension, from deep to shallow, by wide to narrow groove 11, the bosom of this groove 11 is no more than the reaming bosom, and the widest position is no more than the maximum diameter of reaming.At reaming one side fluting, then two reamings all at identical clockwise fluting, are promptly all extended fluting in counterclockwise direction in the clockwise direction or all as only.For holing conveniently, through hole 10 is preferred with the shaft axis by spool 3, and the disalignment line also is feasible.
