Abstract
The utility model provides an oxygen reducing valve capable of being connected rapidly. The oxygen reducing valve comprises a valve body, an adjusting screw rod, a gas inlet, a gas outlet and two pressure gages, wherein the adjusting screw rod is arranged on the valve body; the gas inlet is formed in the bottom of the valve body; a connecting piece is arranged at the gas outlet and provided with a gas outlet passageway communicated with the gas outlet; and at least two circular arc bosses which are used for clamping an oxygen outlet pipe are surrounded on the inner side of the gas outlet passageway uniformly. The oxygen reducing valve is good in sealing performance, convenient to use, simple in structure and long in service life, and the reducing valve and an oxygen pipe can be frequently and rapidly mounted and dismounted.
Description
Technical field
The utility model relates to the industrial instruments field, is specifically related to connect fast oxygen pressure reducing valve.
Background technique
Reduction valve is by regulating, inlet pressure is reduced to the outlet pressure of a certain needs, and the energy of dependence medium itself, make outlet pressure automatically keep stable valve, from hydromechanical viewpoint, reduction valve is a throttle element that local resistance can change, by changing orifice size, the kinetic energy of flow velocity and fluid is changed, cause the different pressure losses, thereby reach the purpose of decompression, then rely on the adjusting of controlling with regulating system, fluctuation and the spring force of downstream pressure are balanced each other, make downstream pressure keep constant in certain margin of error, place, reduction valve air outlet commonly used is general direct to be socketed on air outlet with pipe, in use, the pipeline of joint, air outlet easily produces aging, the valve port sealing of giving vent to anger is poor, easily produce gas leakage, while needing to change, pipe is pulled up cumbersome from reduction valve, and it is also more difficult that pipe is installed, replacing speed can't improve, more can not carry out clutch with reduction valve frequently with the root pipe.
Summary of the invention
Technical problem to be solved in the utility model is to provide quick connection oxygen pressure reducing valve, and good airproof performance is easy to use, can be frequently and carry out fast the installation and removal between reduction valve and oxygen bleed line, and simple in structure, long service life.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: connect fast oxygen pressure reducing valve, comprise valve body, be located at adjusting screw rod on valve body, be located at suction port, air outlet and two pressure gauges of valve body bottom, described air outlet is provided with a link, described link is provided with the air outlet passage be communicated with air outlet, and passage inboard uniform ring in described air outlet is provided with at least two arc cams for the clamping oxygen bleed line.
As preferably, described arc cam adopts two, simple in structure, easy for installation, when oxygen bleed line is plugged on link, can effectively oxygen bleed line be fixed on link.
As preferably; the port that is positioned at the air outlet passage on described link is provided with oxygen bleed line snapping face; described oxygen bleed line snapping face is provided with annular groove; when oxygen bleed line and outlet passageway produce certain gas leakage; can play and again protect oxygen to produce leakage; oxygen cylinder is safer in use, good airproof performance.
As preferably, described oxygen bleed line snapping face is provided with at least one locating slot, between oxygen bleed line and link, snapping is convenient, when oxygen bleed line need to be connected on link, the locating stud snapping at oxygen bleed line snapping place is inserted to locating slot, just can guarantee that the orientation between oxygen bleed line and link is correct, the user needn't worry whether oxygen bleed line is good being connected on oxygen cylinder.
As preferably, described locating slot adopts two, and uniform ring is located on oxygen bleed line snapping face, oxygen bleed line and link is located when pegging graft more accurate.
As preferably, described link and air outlet adopt screw connection structure, make to be connected more firmly between link and reduction valve, in use are difficult for producing valve body and separate with link.
As preferably, described valve body bottom is provided with a safety valve, uses safety, and when system pressure surpasses safety valve setting pressure, safety valve is opened, and prevents overpressure, causes danger.
Beneficial effect:
The utility model adopts technique scheme that quick connection oxygen pressure reducing valve is provided, simple in structure, when oxygen bleed line need to connect the oxygen cylinder reduction valve, only oxygen bleed line need be snapped onto on link, just can use the oxygen in oxygen cylinder, fixing of the assurance oxygen bleed line that on link, the arc cam of oxygen outlet passageway inboard can be good and link, when oxygen bleed line inserts outlet passageway, arc cam can play the effect of blocking the oxygen hose interface, make oxygen hose be difficult for dropping, good airproof performance, easy to use, can be frequently and carry out fast the installation and removal between reduction valve and oxygen bleed line, simple in structure, long service life.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, connect fast oxygen pressure reducing valve, comprise valve body 2, be located at the adjusting screw rod 6 on valve body 2, the suction port 1 that is located at valve body 2 bottoms, air outlet 4 and two pressure gauges 7, described air outlet 4 is provided with a link 5, described link 5 is provided with the air outlet passage 54 be communicated with air outlet 4, and passage 54 inboard uniform ring in described air outlet are provided with at least two arc cams for the clamping oxygen bleed line 51; Described arc cam 51 adopts two; The port that is positioned at air outlet passage 54 on described link 5 is provided with oxygen bleed line snapping face 55, and described oxygen bleed line snapping face 55 is provided with annular groove 52; Described oxygen bleed line snapping face 55 is provided with at least one locating slot 53; Described locating slot 53 adopts two, and uniform ring is located on oxygen bleed line snapping face 55; Described link 5 adopts screw connection structure with air outlet 4; Described valve body 2 bottoms are provided with a safety valve 3.
During real work, reduction valve suction port 1 is connected on oxygen cylinder, before use, first oxygen bleed line and link 5 are carried out to snapping, then open oxygen cylinder, oxygen enters valve body 2 by suction port 1, the control of being undertaken oxygen pressure by adjusting screw rod 6, when the pressure shown on oxygen gauge 7 reaches the needed pressure of user, enter link 5 by air outlet 4, thereby offering the user uses, during overpressure on reduction valve, inner unnecessary pressure can be discharged by safety valve 3, to reach required pressure, make oxygen cylinder safer in use, good airproof performance, easy to use, can be frequently and carry out fast the installation and removal between reduction valve and oxygen hose, simple in structure, long service life.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
