Detailed description of the invention
Hereinafter also describe the present invention in detail with reference to accompanying drawing in conjunction with the embodiments.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.
As shown in Fig. 1 to 5, according to embodiments of the invention, welding nitrogen charging device comprises nitrogen blanketing valve 30, also comprise and fill nitrogen sleeve 10, fill on nitrogen sleeve 10 and be provided with control part, control part detects nitrogen blanketing valve 30 and is filling the bonding station on nitrogen sleeve 10, and according to the break-make of this position control nitrogen.Control part filling the position in nitrogen sleeve 10 and control the break-make of nitrogen, blocks nitrogen when not needing to fill nitrogen according to nitrogen blanketing valve 30, and the waste avoiding nitrogen to be in circulation status all the time causing, reduces production cost.
Wherein, welding nitrogen charging device also comprises source of the gas (not shown), and fill nitrogen sleeve 10 and be connected between source of the gas and nitrogen blanketing valve 30, source of the gas is used for providing nitrogen.In the present embodiment, source of the gas comprises for nitrogen pipe and is arranged on for the interior control valve controlling nitrogen break-make of nitrogen pipe.Fill nitrogen sleeve 10 to be connected with for nitrogen pipe, nitrogen blanketing valve 30 with fill nitrogen sleeve 10 and be connected, form complete flow of nitrogen gas passage.Control part is fixedly installed on and fills on nitrogen sleeve 10, and is connected with control valve, controls the opening and closing of control valve, to control the break-make of nitrogen.
In conjunction with see shown in Fig. 2 and 3, fill the channel of nitrogen 40 nitrogen sleeve 10 being provided with and running through and fill nitrogen sleeve 10, channel of nitrogen 40 is communicated with for nitrogen pipe, nitrogen blanketing valve 30 stretches in channel of nitrogen 40 from the first end filling nitrogen sleeve 10, control part detects the position of nitrogen blanketing valve 30 in channel of nitrogen 40, to control the break-make of nitrogen.Concrete control procedure is as follows, and nitrogen blanketing valve 30 stretches into and fills in nitrogen sleeve 10, and control part detects nitrogen blanketing valve 30, and namely showing needs to fill nitrogen, then control part sends control signal, and nitrogen is circulated, and starts to fill nitrogen; When without the need to filling nitrogen, nitrogen blanketing valve 30 shifts out from filling in nitrogen sleeve 10, and control part can't detect nitrogen blanketing valve 30, and namely show now not need to fill nitrogen, then control part sends signal, and nitrogen is blocked, and stops filling nitrogen.Can carry out as required filling nitrogen like this, nitrogen need not be in circulation status always, saves nitrogen, avoids waste, decreases production cost.
Preferably, the first end of channel of nitrogen 40 has and is convenient to nitrogen blanketing valve 30 and enters the guide structure 11 filled in nitrogen sleeve 10.This guide structure 11 extends internally from the end face of the first end filling nitrogen sleeve 10, and cross section reduces gradually, to play guide effect to nitrogen blanketing valve 30, facilitates nitrogen blanketing valve 30 to enter and fills nitrogen sleeve 10, improves installation effectiveness, saves the set-up time.
More preferably, fill on nitrogen sleeve 10 and be fixedly installed finite place piece 13, locating part 13 limits nitrogen blanketing valve 30 and stretches into length in channel of nitrogen 40.In the present embodiment, locating part 13 is caging bolt, and caging bolt stretches in channel of nitrogen 40, and controlling position is between locating part 13 and the first end filling nitrogen sleeve 10, to ensure that control part can detect nitrogen blanketing valve 30, avoid nitrogen blanketing valve 30 to stretch into the length of channel of nitrogen 40 long simultaneously.
The second end filling nitrogen sleeve 10 is provided with thread segment 12, and thread segment 12 is for being connected with for nitrogen pipe.In the present embodiment, stretch in channel of nitrogen 40 from the second end filling nitrogen sleeve 10 for nitrogen pipe, and with fill nitrogen sleeve 10 and be threaded.Screw connection structure is firm, and good airproof performance is avoided nitrogen to leak causing waste.
In conjunction with shown in Figure 4, control part comprises microswitch 20, microswitch 20 is fixedly installed on the position near the first end filling nitrogen sleeve 10, and the contact of microswitch 20 is positioned at channel of nitrogen 40, the contact of microswitch 20 can be touched when nitrogen blanketing valve 30 stretches in channel of nitrogen 40, namely nitrogen blanketing valve 30 is detected after microswitch 20 is touched, microswitch 20 sends control signal after being subject to the shake-up of nitrogen blanketing valve 30, control signal controls control valve and opens, nitrogen in source of the gas is circulated, place to be welded is filled with after the channel of nitrogen 40 of nitrogen through overcharging nitrogen sleeve 10 and nitrogen blanketing valve 30.
Preferably, control valve is magnetic valve, and microswitch 20 is electrically connected with magnetic valve.Microswitch 20 accuracy of detection is high, and the signal of telecommunication controls fast response time, is conducive to accurate control.
More preferably, arrange a unwrapping wire groove 14 at the top filling nitrogen sleeve 10, the electric wire of the connection between microswitch 20 and magnetic valve is placed in unwrapping wire groove 14.Connection electric wire so both can be made clean and tidy, avoided mixed and disorderly connection electric wire to affect work, be convenient to again depositing of whole device, neat and artistic.
In conjunction with shown in Figure 5, in the present embodiment, nitrogen blanketing valve 30 is copper pipe, and in other embodiments, nitrogen blanketing valve 30 can be the pipe that other does not affect the material that fills nitrogen and welding and makes.Nitrogen process of filling during refrigeration system pipeline welding is as follows:
When needs fill nitrogen, fill the second end of nitrogen sleeve 10 and being connected for nitrogen pipe of source of the gas, then being stretched into from the first end filling nitrogen sleeve 10 by nitrogen blanketing valve 30 fills in nitrogen sleeve 10, when nitrogen blanketing valve 30 touches the contact of the microswitch 20 in channel of nitrogen 40, microswitch 20 sends control signal, and magnetic valve is opened after receiving control signal, nitrogen goes into circulation, start to fill nitrogen to refrigeration system pipeline, when nitrogen blanketing valve 30 touches the locating part 13 in channel of nitrogen 40, nitrogen blanketing valve 30 is no longer deep.
When filling after nitrogen completes, extracted out from filling in nitrogen sleeve 10 by nitrogen blanketing valve 30, microswitch 20 disconnects, and magnetic valve cuts out thereupon, and nitrogen ends, and stops filling nitrogen.The break-make of nitrogen can be controlled by said process according to demand, avoid nitrogen to circulate always and cause waste.
This welding touches microswitch 20, the opening and closing of microswitch 20 Controlling solenoid valve when being inserted with nitrogen charging device filled nitrogen sleeve 10 by nitrogen blanketing valve, finally reaches the function controlling nitrogen and whether circulate.Process duct is filled nitrogen post and is used the circulation of solenoid control nitrogen, circulates when filling nitrogen, and when not filling nitrogen, nitrogen is closed, and can save (15s-3s)/the nitrogen of (15s+3s) * about 100%=66%, have the effect well avoiding nitrogen to waste.
As can be seen from the above description, the above embodiments of the present invention achieve following technique effect: only fill nitrogen when welding needs, do not fill nitrogen At All Other Times, greatly reduce the waste of nitrogen, cost-saving; The control mode fast response time of microswitch and magnetic valve, controls reliable.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
