Description
Technical field
The utility model is related to the gas delivery nozzle of gas, and espespecially one kind can be fitted to different calorific value gas
The nozzle arrangements of the adjustable tolerance in source.
Background technology
The domestic gas fuel of Taiwan, is broadly divided into two kinds of liquefied petroleum gas and natural gas.Liquefied petroleum gas
Principal component be propane (C3H8), with butane (C4H10) mix, it is at normal temperatures and pressures gas, pressurized (or cooling) can
Liquefaction, loads steel cylinder and uses, so being commonly called as barreled gas.
Natural gas is from liquefied petroleum gas in addition to constituent is different, and its calorific value is also different.Wherein because natural gas is
Calculated with volume, calorific value is low；And liquefied petroleum gas is that by weight, calorific value is high.
So-called calorific value is the heat that per kilogram substance combustion is put, 16 grams of methane one mole, one kilogram of 62.5 moles, calorific value
It is 54937kJ, if reduced unit is into card, 1 kilogram of methane burns can produce 11,946kcal completely；But because natural gas is with body
Product metering, its calorific value is every stere 8900kcal to 9900kcal.As for 44 grams of propane one mole, one kilogram 22.7 is rubbed
You, calorific value is 50045kJ；And liquefied petroleum gas is to measure by weight, the net heat of 12,000kcal is produced thus about per kilogram
Value.
Furthermore, " nozzle bore and outlet pressure are the important key for determining firepower size, the larger stream of liquefied petroleum atmospheric pressure
It is fast fast, " by taking gas oven as an example：" nozzle of barreled gas stove is small compared with the nozzle of casinghead gas stove." in order to reach identical firepower
Calorific value, the small nozzle of gas oven gas output using liquefied petroleum gas is small, and the gas oven gas output using natural gas is big, nozzle
Greatly.If but by the less nozzle of the bore of barreled gas water heater and gas oven, reconfiguration pressure and the less natural gas of calorific value, meeting
The situation for producing firepower not strong because gas output is small.If conversely, the water heater of natural gas to be attached to the gas of barreled, that consequence
Will be more serious, because the nozzle bore of natural gas is than larger, and the pressure ratio of barreled is larger, once the gas output mistake of liquefied petroleum gas
It is big to be ignited again, gently then there is excessive fuel and waste, imperfect combustion is susceptible to, and produce the situation of the bottom of a pan carbon distribution；It is heavy then
Probably due to fire is too prosperous and cause fire, especially water heater is even more dangerous.
In this way, it is known that in response to the gas nozzle of natural gas different pore size of thus arranging in pairs or groups different from the calorific value of liquefied petroleum gas,
Figure 1A is refer to, its display natural gas gas nozzle, Figure 1B display liquefied petroleum gas gas nozzles, wherein, because of heating value of natural gas
Small, so that larger gas output, therefore its nozzle bore X is also larger, conversely, because liquefied petroleum gas calorific value is big, thus only need to be compared with
Small gas output is that can obtain being expected combustion efficiency, therefore its nozzle bore Y is smaller, and, if being intended to the use by gas is changed in the future
Source, buys the gas nozzle of different pore size very to have inconvenience in response to it for the user, or even, do not known about for some
Natural gas need to be connected the user of respective aperture gas nozzle with liquefied petroleum gas, thus wrong nozzle causes the hair of above-mentioned danger
It is raw；Therefore, problem above of the present inventor caused by solution known nozzle, inventing one kind can be in response to two kinds of different calorific value pressure
The nozzle arrangements of the barreled gas of power size or the adjustable tolerance of natural gas gas.
Utility model content
The purpose of this utility model is to provide a kind of nozzle arrangements of adjustable tolerance, according to this in response to different calorific values watt
This source.
It is of the present utility model another object is that for manufacture end be easy to production, reduce quantity in stock, and be easy to sales end stock with
Reduces cost, barreled gas or natural gas gas that calorific value pressure is adapted to size are adjusted in when side is installed, and allow consumer (to make
User) any follow-up adjustment need not be done, with up to maximum security.
It is that, up to object defined above, the utility model uses following technical scheme：
A kind of nozzle arrangements of adjustable tolerance, are applied on various gas, mainly include：
