Abstract
The utility model discloses a choke valve of gaseous mixture for self-feeding pressure-free gas torch, comprising a valve body, which is characterized in that: a knob-type screw is arranged on the valve body. When the self-feeding pressure-free gas welding and cutting device is operating in upper air of ten to twenty meters high (such as the application to shipbuilding or building industry), the choke valve of gaseous mixture must be opened to increase the flow and advance the suction; then, the choke valve can be regulated if only the operator screws the knob-type screw by hand with convenient regulation and safe usage. The utility model overcomes the drawback prior in the prior art and facilitates the popularization and application of self-feeding pressure-free gas welding and cutting device.
Description
The utility model relates to a kind of welding and cutting device accessory, refers in particular to a kind of self-sucktion type pressure free gasoline welding-cutting torch mist flow-limiting valve.
At present, except carrying out vapor phase soldering, the soldering with traditional oxy-acetylene flame, also useful natural gas, liquefied gas act as a fuel and weld, above-mentioned fuel cost height, poor stability.For this reason, people attempt using gasoline for the fuel replace ethine, design some gasoline oxygen cutting welding equipments, as: " gasoline fusing soldering welder and soldering set thereof " (ZL00265188, CN2454644Y) etc., and the most good be the self-sucking no-pressure gasoline welding and cutting device, as: " self-sucktion type pressure free gasoline welding-cutting torch " (application number: 01106001, but structurally there is defective in their used mist flow-limiting valves, have influenced applying of they CN1296149) etc..The self-sucking no-pressure gasoline welding and cutting device need not to regulate flow-limiting valve when grading operation, because of the gasoline welding cutting torch is self-priming, and no pressure in the fuel tank, flow-limiting valve is worked in rated range; (as being used for shipbuilding industry, building industry etc.) must open flow-limiting valve when the 10m-20m operation of high-altitude, and enlargement discharge improves suction.Flow-limiting valve of the prior art, when work high above the ground, the operator wants hand to take screwdriver that flow-limiting valve is regulated, and exists unsafe hidden danger.
The purpose of this utility model is to overcome the defective that prior art exists, and a kind of self-sucktion type pressure free gasoline welding-cutting torch mist flow-limiting valve is provided, and it is easy to adjust, and is safe in utilization.
For achieving the above object, the solution that the utility model is taked is: a kind of self-sucktion type pressure free gasoline welding-cutting torch mist flow-limiting valve, comprise valve body, and it is characterized in that on valve body, being equipped with a knob bolts.
The self-sucking no-pressure gasoline welding and cutting device is (as being used for shipbuilding industry, building industry etc.) when the 10m-20m operation of high-altitude, must open the mist flow-limiting valve, enlargement discharge, improve suction, at this moment, the operator is as long as one revolve knob bolts and can regulate flow-limiting valve lightly with hand, and is easy to adjust, safe in utilization.The utility model has overcome the defective that prior art exists, and helps applying of self-sucking no-pressure gasoline welding and cutting device.
Below in conjunction with embodiment and accompanying drawing thereof utility model is remake description.
Fig. 1 is the right view of present embodiment.Fig. 2 is the front view of present embodiment.Fig. 3 is the A-A cutaway view of Fig. 2.Fig. 4 is the structural representation of knob bolts 2 among Fig. 1-Fig. 3.
As shown in Figure 1-Figure 3, a kind of self-sucktion type pressure free gasoline welding-cutting torch mist flow-limiting valve comprises valve body 1, it is characterized in that being equipped with on valve body 1 knob bolts 2.As shown in Figure 3 and Figure 4, described knob bolts 2, its nut and screw rod are one, and screw rod is divided into thimble part, double-screw bolt part, step part, hermetic unit, important actor part from top to bottom, and hermetic unit is placed with O-ring seals 21.
Claims (2)
1, a kind of self-sucktion type pressure free gasoline welding-cutting torch mist flow-limiting valve comprises valve body (1), it is characterized in that: a knob bolts (2) is housed on valve body (1).
2, a kind of self-sucktion type pressure free gasoline welding-cutting torch mist flow-limiting valve according to claim 1, it is characterized in that: described knob bolts (2), its nut and screw rod are one, screw rod is divided into thimble part, double-screw bolt part, step part, hermetic unit, important actor part from top to bottom, and hermetic unit is placed with O-ring seals (21).
