Description

Multifunctional liquefied gas monitor

The utility model relates to a kind of liquefied gas, the matching used security apparatus of natural gas kitchen range, particularly a kind of multifunctional solution gasification watch-dog that is used to monitor gas leak and steel cylinder internal memory atmospheric pressure.

At present, the resident uses liquefied gas, mostly is to adopt liquefied gas bottle directly to be connected with kitchen range through pressure-reducing valve, uses dangerous.

It is a kind of safe in utilization and can show that liquefied gas bottle deposits the multifunctional solution gasification watch-dog of atmospheric pressure that the purpose of this utility model is to provide.

For achieving the above object, the utility model adopts following technical proposals: the utility model is the same with pressure-reducing valve of the prior art, includes a housing that air inlet and gas outlet are arranged, and pressure-reducing valve is housed in shell air inlet.Be characterized in: with inlet channel that shell air inlet is connected on Pressure gauge and flow chart are housed.In use, inlet channel connects liquefied gas bottle, and the gas outlet connects kitchen range.In the use, Pressure gauge demonstrates the atmospheric pressure of depositing of liquefied gas bottle at any time, also just knows the tolerance of depositing in the liquefied gas bottle.And flow chart can demonstrate the flow direction of air-flow in the inlet channel.Sew thereby can detect whether to have on the air flue.For example, if close kitchen range, still have the air-flow positive flow to cross flow chart, illustrate to have to the kitchen range section and sew at flow chart; If close the switch of closing liquefied gas bottle behind the kitchen range again, there is reverse air-flow to cross flow chart, illustrate then that flow chart has to the liquefied gas bottle section to sew.

Air outlet valve by mechanical timer control can be housed in described housing gas outlet.Like this, just can carry out timing controlled to kitchen range usefulness gas, even the people leaves when using kitchen range, can be because of not forgetting that closing liquefied gas causes the waste liquefied gas with accidents happened yet.

This liquefied gas watch-dog can also be equipped with the superpressure warning device, to prevent the superpressure explosion accident.The structure of this superpressure warning device can be designed as: on the housing inlet channel constant pressure valve is housed, lower housing portion has reservoir; The outlet of constant pressure valve is communicated with the import of reservoir, and buzzer is equipped with in the outlet of reservoir.When superpressure occurring, air pressure backs down constant pressure valve, and liquid gas flow is in constant pressure valve enters the reservoir of lower housing portion, and liquefied gas is dissolved in the water, and aqueous vapor is impacted its spring leaf and sounded the alarm through the buzzer in the exit of reservoir then, enters in the atmosphere.The aqueous vapor of Pai Chuing is nontoxic like this, gives the alarm again.

The utility model has conspicuous advantage compared with prior art: the utility model can demonstrate the depositing tolerance, can be used for detecting the sewing of air flue of liquefied gas bottle, can timing controlled kitchen range usefulness gas and superpressure exhaust and warning, thereby safe and convenient to use.

Accompanying drawing is the structural representation of an embodiment of the present utility model.

An optimum implementation of the present utility model is: referring to accompanying drawing, this multifunctional solution gasification watch-dog includes a housing 29 that air inlet 2 and gas outlet 25 are arranged, and on the inlet channel that housing 29 air inlets 2 connect Pressure gauge 1, flow chart 4 and constant pressure valve 9 is housed.Flow chart 4 is that an impeller box 5 is housed in the shell, and by adorning an impeller, pointer 3 is equipped with in the upper end of impeller 6 central shafts in the impeller box 5.Out-of-date when air flow stream, impeller 6 rotates, and rotates with driving pointer, indicates the flow direction of air-flow.Pressure gauge 1 adopts commercially available air gauge.Constant pressure valve 9 is that the lower end of a skin plug valve 7 is supported by spring 8, and the spring force of spring 8 is determined the setting pressure of constant pressure valve 9 by the thread support adjustment of its lower end, and when air pressure surpassed setting pressure, constant pressure valve 9 was opened venting.In housing 29 air inlets 2 pressure-reducing valve 12 is housed.The aperture of pressure-reducing valve 12 is by 21 controls of a shift fork, and the governor motion of shift fork 21 is made of spring 18, pressure regulating axis 16, movable block 14 and tap changer knob 15.So rotation tap changer knob 15 just can be adjusted the aperture of pressure-reducing valve 12.The air outlet valve 24 of mechanical timer 30 controls is housed in housing 29 gas outlets 25.Shift fork 27 of one dog, 28 controls is arranged below the timer 30, and shift fork 27 lower ends are by sealing the push rod that air film 26 withstands vent valve 24, and spring 23 supportings are arranged at the push rod bottom.During use, timer 30 is opened, and then dog 28 moves down, and makes shift fork 27 push the push rod of envelope air film 26 and vent valve 24 open, and vent valve 24 is opened.After the time that timer 30 is set arrives, move on the dog 28, lean on the elastic force of spring 23 that vent valve 24 cuts out.Housing 29 bottoms connect the shell 13 that transparent material is made, and constitute reservoir 17 in it.Separate with epithelium 22 between reservoir 17 and the housing 29 top inner chambers.The outlet 10 of constant pressure valve 9 is by the import of flexible pipe 11 connection reservoirs 17, and buzzer 20 is equipped with in the outlet of reservoir 17.When the liquefied gas superpressure, constant pressure valve 9 is opened, and liquefied gas flows into reservoirs 17 and is dissolved in the water through constant pressure valve 9, and the high pressure aqueous vapor is from buzzer 20 ejections of reservoir outlet, impacts the spring leaf 19 in the buzzer 20 and sends chimes of doom.
