Description
The utility model relates to a kind of gas valve, and specifically a kind of valve that is used for stable and adjustments of gas flow pressure is particularly suitable for use between gas pressure reducer and the welding machine and provides stable gas flow for welding machine.
When existing gas welding device is worked, generally all is that the gas in the gas cylinder is directly entered welding machine after the decompressor decompression, and welds with welding gun.There is following deficiency in this welding manner: when 1, starting the welding of welding machine equipment at every turn, because gas flow is violent especially, variations in flow presents moment supercharging and augmented flow phenomenon, thereby welding current is also big relatively, cause the failure welding with lower thin sheet easily, even cause the weld perforation 0.6mm; 2, waste gas and time; 3, can not satisfy the high quality welding technical requirements.
The purpose of this utility model is intended to overcome above-mentioned the deficiencies in the prior art, even propose a kind of voltage stabilization and current stabilization modulating valve that gas flow is stable and the flow adjustable size saves that also can make when starting device.
Realize the technological scheme of above-mentioned purpose: a kind of voltage stabilization and current stabilization modulating valve, it is characterized in that: be provided with voltage stabilizing mechanism and flow control device, voltage stabilizing mechanism is by valve body, bonnet, the chamber is regulated in voltage stabilizing and addendum cone is formed, valve body is threaded with bonnet, form voltage stabilizing between valve body and the bonnet and regulate the chamber, the built-in addendum cone in chamber is regulated in voltage stabilizing, addendum cone socket pressure regulating spring, on the valve body of addendum cone lower end, have inlet hole, voltage stabilizing is regulated the chamber and is set out pore by valve body, flow control device is made up of modulating valve and Flow-rate adjustment awl, modulating valve is threaded with valve body, the front end of modulating valve has the inlet hole that communicates with the air outlet hole in voltage stabilizing adjusting chamber, and the Flow-rate adjustment awl that has outlet passageway is threaded with the Flow-rate adjustment chamber of modulating valve, and the awl point of Flow-rate adjustment awl is over against the front end inlet hole of modulating valve.
The bottom of addendum cone has the horizontal adjustment hole, and the top of addendum cone is hollow tube, and the horizontal adjustment hole communicates with hollow tube.
Socket elastic seal ring on the addendum cone at pressure regulating spring two ends.
The neck socket elastic seal ring of Flow-rate adjustment awl.
Even interval is provided with 3 taper holes that communicate with outlet passageway for 120 ° on the neck circumference of Flow-rate adjustment awl.
Adopt technique scheme, the utility model beneficial technical effects is: 1, by voltage stabilizing mechanism is set, the greater impact air-flow that flows out from decompressor during with device start is regulated in the voltage stabilizing of voltage stabilizing mechanism and is obtained in the chamber discharging and buffering, makes it regulate the soft steady gas of output in the chamber from voltage stabilizing.2,, change the feeding degree of Flow-rate adjustment awl, thereby adjustments of gas flow size satisfies the different size requirements of different welding machines to gas flow at the flow suction port by flow control device is set.3, because welding machine is a kind of equipment of frequent starting, behind current stabilization, not only impact air-flow can not occur, improve welding quality, shorten working hours, increase work efficiency.And, significantly reduced the waste of unnecessary gas: use through reality to show, adopt the utility model, can save gas 20%～40%! The utility model is simple in structure, ingenious, is the extremely strong voltage stabilization and current stabilization modulating valve of a kind of practicability.
Below by embodiment in detail, and its structure is described in detail in conjunction with the accompanying drawings:
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment: with reference to Fig. 1, a kind of voltage stabilization and current stabilization modulating valve, comprise voltage stabilizing mechanism and flow control device, voltage stabilizing mechanism is by valve body 13, bonnet 1, chamber 16 is regulated in voltage stabilizing and addendum cone 2 is formed, valve body 13 is threaded with bonnet 1, form voltage stabilizing between valve body 13 and the bonnet 1 and regulate chamber 16, chamber 16 built-in addendum cones 2 are regulated in voltage stabilizing, addendum cone 2 socket pressure regulating springs 17, the bottom of addendum cone 2 has horizontal adjustment hole 15, the top of addendum cone 2 is hollow tube 4, horizontal adjustment hole 15 communicates with hollow tube 4, the addendum cone 2 socket elastic seal rings (3 at pressure regulating spring 17 two ends, 5), on the valve body 13 of addendum cone 2 lower ends, have inlet hole 14, surely, press adjusting chamber 16 to set out pore 12 by valve body 13, flow control device is made up of modulating valve 7 and Flow-rate adjustment awl 9, modulating valve 7 is threaded with valve body 13, the front end of modulating valve 7 has the inlet hole 11 that communicates with the air outlet hole 12 in voltage stabilizing adjusting chamber 16, the Flow-rate adjustment awl 9 that has outlet passageway 8 is threaded with the Flow-rate adjustment chamber of modulating valve 7, the neck socket elastic seal ring 10 of Flow-rate adjustment awl 9, the awl point 6 of Flow-rate adjustment awl 9 is over against the front end inlet hole 11 of modulating valve 7, and even interval is provided with 3 taper holes 18 that communicate with outlet passageway 8 for 120 ° on the neck circumference of Flow-rate adjustment awl 9.
During work, change the tension force of pressure regulating spring 17, thereby regulate the gas pressure in the voltage stabilizing adjusting chamber 16 by rotation bonnet 1.When the welding machine running hours, according to the pressure of setting, keep certain slit between the lower end of addendum cone 2 and the valve body inlet hole 14, gas is unimpeded.When welding machine is discrete intermittent working state, because pressure changes, addendum cone will be made bob under the effect of pressure regulating spring 17, and sufficient up and down amplitude of beating is big more, flow is big more, thereby realize changing air demand and pressure adjustment, make the stable purpose within the specific limits of gas pressure.When welding machine was stopped using, addendum cone 2 was sealed inlet hole 14, stops air feed.The Flow-rate adjustment of welding machine gas is by the screw thread process between adjustment Flow-rate adjustment awl 9 and the modulating valve 7, thereby changes the feeding degree of the awl point 6 of Flow-rate adjustment awl 9 over against the front end inlet hole 11 of modulating valve 7, realizes the flow control to eluting gas.
