Description
Technical field
The utility model relates to welder technical field, particularly relates to a kind of Novel self-closed type welding gun.
Background technology
As everyone knows, welding gun is that a kind of high temperature that utilizes imflammable gas acutely to burn to produce is realized the welder of weld metal parts, is widely used in field of machining; Existing welding gun, generally include welded tube and handle, welded tube is fixed on handle, one end of welded tube is provided with tip, the other end is provided with air inlet pipe, air inlet pipe place is provided with intake valve, is provided with control valve on welded tube, and the air inlet of intake valve control welding gun opens and closes, control valve is for regulating the gas output of welding gun in the time of welding job, to regulate burning gases size; Because intake valve is born compared with large air pressure and the air pressure holding capacity of control valve is less than intake valve, after the long-term use of this welding gun, the problem that exists the air-tightness decline of intake valve even to damage, when user closes after control valve, welding gun internal gas pressure is raise, easily leak air, the safety issue such as booster.
Utility model content
For solving the problems of the technologies described above, the utility model provides one can effectively detect intake valve air-tightness, reminds in time and automatic closed air inlet pipe, effectively improves the Novel self-closed type welding gun of security performance.
Novel self-closed type welding gun of the present utility model, comprise tip, welded tube and handle, on described welded tube, be provided with air inlet pipe and be provided with intake valve at air inlet pipe place, the outlet side of described welded tube is provided with control valve, on described welded tube, be also set to current stabilization air chamber, on described current stabilization air chamber, be connected with electronics barometer, on described handle, be provided with power pack and control chip, on described welded tube, be provided with buzzer, in described air inlet pipe, be also provided with magnetic valve, described electronics barometer, power pack, buzzer, magnetic valve are all connected with described control chip.
Further, be also provided with display on described handle, described display is connected with described control chip.
Further, be also provided with temperature sensor on described welded tube, described temperature sensor is connected with described control chip.
Further, the outlet side of described welded tube is also provided with check valve.
Further, described check valve is ceramic one-way valve, and described check valve is arranged on the end along airflow direction in welded tube.
Further, described tip is ceramic tip.
Compared with prior art the beneficial effects of the utility model are: comprise tip, welded tube and handle, on welded tube, be provided with air inlet pipe and be provided with intake valve at air inlet pipe place, the outlet side of welded tube is provided with control valve, on welded tube, be also set to current stabilization air chamber, on current stabilization air chamber, be connected with electronics barometer, on handle, be provided with power pack and control chip, on welded tube, be provided with buzzer, in air inlet pipe, be also provided with magnetic valve, electronics barometer, power pack, buzzer, magnetic valve are all connected with control chip; Like this, in the time that intake valve exists closed-ended question, the air pressure of current stabilization air chamber raises, and electronics barometer detects when air pressure is elevated to a certain degree, control chip control solenoid closure, cuts off air inlet pipe, simultaneously automatically, buzzer starts, and reminds user's intake valve to have closed-ended question, improves security; Under normal circumstances, magnetic valve is in normally open.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, Novel self-closed type welding gun of the present utility model, comprise tip 1, welded tube 2 and handle 3, on welded tube, be provided with air inlet pipe 4 and be provided with intake valve 5 at air inlet pipe place, the outlet side of welded tube 2 is provided with control valve 9, on welded tube 2, be also set to current stabilization air chamber 7, on current stabilization air chamber 7, be connected with electronics barometer 8, on handle 3, be provided with power pack 12 and control chip, on welded tube 2, be provided with buzzer 11, in air inlet pipe 4, be also provided with magnetic valve 6, electronics barometer, power pack, buzzer, magnetic valve are all connected with control chip; Like this, in the time that intake valve exists closed-ended question, the air pressure of current stabilization air chamber raises, and electronics barometer detects when air pressure is elevated to a certain degree, control chip control solenoid closure, cuts off air inlet pipe, simultaneously automatically, buzzer starts, and reminds user's intake valve to have closed-ended question, improves security; Under normal circumstances, magnetic valve is in normally open; In addition, current stabilization air chamber also has the effect of the stable air pressure of giving vent to anger, and while preventing welding gun use, flare is suddenly big or suddenly small.
Novel self-closed type welding gun of the present utility model, is also provided with display on handle, display is connected with control chip; Like this, the air pressure situation in welding gun may be displayed on display.
Novel self-closed type welding gun of the present utility model, is also provided with temperature sensor on welded tube, temperature sensor is connected with control chip; Like this, in the time that the thermal insulation of welding gun leading portion goes wrong, easily there is the problem of booster in welding gun, and in the time that abstinence temperature is arrived in temperature rise, control chip control magnetic valve cuts out automatically, and can remind user by display.
Novel self-closed type welding gun of the present utility model, the outlet side of welded tube is also provided with check valve 10, can prevent that like this air-flow from flowing backwards.
Novel self-closed type welding gun of the present utility model, check valve is ceramic one-way valve, check valve is arranged on the end along airflow direction in welded tube; Like this, security is higher.
Novel self-closed type welding gun of the present utility model, tip is ceramic tip; Like this, security is higher.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
