Embodiment one
Fig. 1 and Fig. 2 are refer to, the embodiment of the present application one provides a kind of differential pressure type of the application offer and adds smelly system, including contains
The verification tank 101 of smelly liquid is filled, liquid level gauge and smelly liquid entrance 1012, liquid supply device 102 and institute are additionally provided with the verification is filled
State smelly liquid entrance 1012 to connect, to supplement smelly liquid to the verification tank 101.The differential pressure type adds smelly system also to include the first gas
It is pressed into mouth and the second air pressure inlet, first air pressure inlet is to connect the first air pressure input and to the differential pressure type plus smelly
System inputs the first air pressure；Second air pressure inlet is to connect the second air pressure input and to the differential pressure type plus smelly system
The second air pressure is inputted, the atmospheric pressure value of second air pressure is more than the atmospheric pressure value of first air pressure.In practical operation, Ke Yitong
The draught head crossed between first air pressure and second air pressure and formed and be pushed to smelly liquid from the liquid supply device 102
Gas pressure power in the verification filling.And the liquid level gauge can for obtain it is described verification fill in smelly liquid level parameter,
And the smelly liquid level parameter is transferred to controller 105, controller 105 can control the difference based on the smelly liquid level parameter
Pressure type adds the running status of smelly system, so that by the draught head between first air pressure and second air pressure, that is,
First pressure difference inputs the smelly liquid in the liquid supply device 102 into the verification tank 101.It is pointed out that in reality
The smelly liquid in liquid supply device 102 can be inputted to the school by first pressure difference in several ways in the operating process of border
Test in tank 101, for example, first pressure difference can be passed into the verification tank 101, directly the smelly liquid in verification tank 101 is entered
Row effect, then input the smelly liquid in liquid supply device 102 into verification tank 101 by the active force of pressure difference；Can also be after general
First pressure difference is passed through the liquid supply device 102, pressure difference is acted on the smelly liquid of liquid supply device 102, so that by smelly liquid
Be pushed to verification tank 101 in, etc..The active force by pressure difference can be accomplished in several ways in actual mechanical process
The smelly liquid in liquid supply device 102 is input in verification tank 101, just do not enumerate herein, user can as needed and voluntarily
Set.

Row state.User can intuitively and easily obtain differential pressure type plus each running state parameter of smelly system by the display device.
User can also carry out operational control by the touch display device 106 and send different controls to the controller 105
System instruction, is opened for example, first control instruction can be sent to the controller 105 with controlling the fluid supplement solenoid valve 1021 to be in
The duration of state is opened, and/or can send the second control instruction to the controller 105 to control the fluid supplement solenoid valve 1021
The duration being closed.It is possible thereby to realize control plus smelly dosage are how many, add smelly time plus smelly frequency etc..It can be seen that,
Differential pressure type in the embodiment of the present application adds smelly system to facilitate by setting touch display device 106 to realize directly perceived
Acquisition differential pressure type add each running state parameter of smelly system, and easily realize to differential pressure type plus smelly system plus smelly processing control
System.Therefore also there is the technique effect for adding smelly operating efficiency and lifting user's use feeling of lifting gas burning system.
Yet further, the touch display device 106 also includes to by the touch display device 106
Circuit system add the flame proof unit 107 that the gas circuit in smelly system is isolated with the differential pressure type.Do not stopping it is possible thereby to realize
Gas burning system work on the premise of and by the touch display device 106 realize pair plus smelly system plus smelly control process.
Therefore, the differential pressure type in the embodiment of the present application adds smelly system also to have further lifting plus the smelly operating efficiency for handling control and behaviour
Make the technique effect of security.
