Abstract
The utility model discloses a gas flow control valve which is characterized in that a valve base is arranged with a gas inlet and a gas outlet, grooves are formed on the valve base, gas holes are formed on the two sides of each groove and communicated with the gas inlet and the gas outlet, a solenoid valve is arranged on each valve base, the valve stem of each solenoid valve is matched with the groove, at least two sets of the grooves and the solenoid valves matched with the grooves are arranged on the valve base, a valve opening is formed on the valve base, the valve opening is in a crossed communication with the gas outlet, a needle valve is arranged inside the valve opening, and the needle valve is in a threaded connection with the valve opening. Due to the structure adopted by the utility model, the gas flow control valve has the advantages of novel structure, low energy consumption, less pollution and the like.
Description
Technical field
The utility model relates to electric welding machine equipment, specifically a kind ofly welds the energy-conservation gas flow regulating valve that presses down the hole device.
Background technique
At present, electric welding machine is mainly used in astrovehicle, automobile, railway, steamer, the metal solder in fields such as building, its principle is that the high-temperature electric arc that utilizes positive and negative polarities to produce when instantaneous short circuit comes scolder and the materials to be welded on the consumable electrode, reach the purpose that makes their combinations, gas cylinder is connected with welding gun through tracheae respectively with electric welding machine, in long-term welding production process, no matter being to use single kind shielding gas still is two kinds of shielding gas weld metals, defectives such as pore that welded joint is all can occurrence degree different and crackle, generally speaking, the single pore that disperses often can butt joint not constitute harm, and under pore and the common situation about existing of crackle, particularly the joint exists the difficult little pore of coming out of checking of x-ray inspection, this is when pore is chain or wire again slightly, under the acting in conjunction of welding interior stress and external force, be easy to cause joint cracking; When large-scale weld assembly is vertically welded; usually form bulge and not exclusively molten phenomenon; flow and flow velocity to shielding gas can not be controlled; cause a large amount of shielding gas to be not fully utilized and slattern; gas can not make full use of and produce a large amount of weldering mists, has polluted environment, has influenced the healthy of welder; simultaneously, reduced welding speed.
Now, a lot of fields all utilize the automation foundation element, solenoid valve particularly, the outstanding feature of solenoid valve is to realize control automatically, solenoid valve both domestic and external is divided into three major types (that is: direct-acting type from principle, multiple step format, leading type), direct action solenoid valve belongs to straight moving piston structure, and it is by valve body, valve pocket, electromagnetic coil, valve rod and spring are formed, be provided with the valve pocket of charged magnetic coil in the valve body, valve rod is connected with the valve pocket suit, and the valve pocket upper end connects through bolt seal, the valve pocket lower end is provided with spring, electromagnetic coil in the control circuit input electrical signal, solenoid valve produces electromagnetic force valve rod is pulled down, and the switching of valve just produces corresponding, during outage, electromagnetic force disappears, and spring force upwards pushes away valve rod, and the switching of valve also produces a correspondence, for the electric welding machine field, using the automation foundation element still is a blank.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned the deficiencies in the prior art, and a kind of automaticity height, the gas flow regulating valve of adjustments of gas flow and flow velocity, novel structure, energy saving arbitrarily are provided.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of gas flow regulating valve is characterized in that being provided with the valve seat of bringing pore and air outlet hole into, and valve seat is provided with groove, and groove is provided with the pore that is connected with inlet hole and air outlet hole, and valve seat is provided with solenoid valve, and the valve rod of solenoid valve matches with groove.
At least be provided with on the valve seat of the present utility model two cover grooves and with the solenoid valve of groove fit.
Valve seat of the present utility model is provided with valve opening, and valve opening intersects with air outlet hole and is communicated with, and is provided with needle-valve in the valve opening, and needle-valve is threaded with valve opening.
The utility model has been realized automation control, by the combination in any of solenoid valve owing to adopt said structure, change the flow size of gas, simultaneously, by adjusting needle-valve, further the flow of control gaseous has advantages such as novel structure, energy saving, reduction pollution.
