Abstract
The utility model discloses a gas pressure monitoring devices belongs to the welding field. Including alarm, automatic control subtotal pressure sampling device, automatic control part respectively with pressure sampling device alarm, electric welding machine connecting, pressure sampling device includes pressure switch, pressure setting device, the minimum pressure value of technological requirement has been set for to the pressure setting device, the gaseous pressure of pressure switch real -time supervision pipeline supply. The utility model discloses can realize the situation of the gaseous supply of real time monitoring through each partial automatic control, prevent the welding quality accident that gaseous supply brought unusually, and work efficiency be high, low in manufacturing cost, has reduced operation workman's intensity of labour, has eliminated quality hidden danger, possesses the value of extensively using widely.
Description
Technical field
This utility model belongs to a kind of welding instrument, specifically, more particularly to a kind of gas pressure monitoring device.
Background technology
During digging machine structural element welding production, often there is gas supply pressure in structural member welding process not
Surely, gas anomaly cut-out etc. abnormal conditions, and operator cannot monitor in real time, easily there are the mass defects such as weld blowhole
Situation, so as to cause quality accident, also has the risk of potential safety hazard and stability difference.And with automatization in commercial production
The raising of degree, when welding job is carried out, only manually carry out checking by operator there is labor intensity height, efficiency is low asks
Topic, and most inspection method can not meet existing practical situation.
Utility model content
This utility model purpose is to provide a kind of gas pressure monitoring device, to overcome workpiece welding seasonal epidemic pathogens in prior art
The defect of the abnormal problems of welded quality for easily causing of body supply.
This utility model employs the following technical solutions realization：A kind of gas pressure monitoring device, including alarm, certainly
Dynamic control section and pressure sampling apparatus, it is described automatically control part respectively with the pressure sampling apparatus, the alarm, electricity
Welding machine connects, and the pressure sampling apparatus include pressure switch, pressure setting device, and the pressure setting device is used for setting work
The minimal pressure force value that skill is required, the pressure switch real-time monitoring pipeline supply the pressure of gas.
The part that automatically controls is comprising circuit protection device, power supply, DC relay.
Compared with prior art, the beneficial effects of the utility model are：This utility model can be by the automatic of each several part
The situation of control realization monitor in real time gas supply, prevents the abnormal welding quality accident brought of gas supply, and the effect that works
Rate is high, low cost of manufacture, reduces the labor intensity of operator, eliminates hidden danger of quality, possesses and be widely popularized the valency for using
Value.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1st, carbon dioxide feeder；2nd, alarm；3rd, automatically control part；4th, electric welding machine；5th, pressure samples dress
Put.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of gas pressure monitoring device, including alarm 2, automatically controls part 3 and pressure samples dress
5 are put, the part 3 that automatically controls is connected with the pressure sampling apparatus 5, alarm 2, electric welding machine 4 respectively, this utility model leads to
The gas supply abnormal quality accident for producing when crossing the pressure of auto-real-time monitoring gas to prevent from welding.
The pressure sampling apparatus 5 include pressure switch, pressure setting device, and pressure setting device sets technological requirement
Minimal pressure force value, the gas pressure of the pipeline supply of pressure switch real-time monitoring carbon dioxide feeder 1, when in pipeline
When gas supply is abnormal, pressure low alarm signal is simultaneously sent to and automatically controls part 3 by pressure switch turn on automatically.
The part 3 that automatically controls automatically controls part 3 by pressure comprising circuit protection device, power supply, DC relay
Alarm signal is converted into control signal through comparing by the alarm signal that sampler 5 is passed over, and control signal is by control
DC relay is automatically stopped welding process, and carries out automatic alarm instruction.
