Abstract
The utility model relates to an automatic controller for excessive pressure in an oxygen bottle. When the pressure in the oxygen bottle is lower than the stated excessive pressure, the automatic controller can automatically close an oxygen path and can ensure the safety of the oxygen bottle in use. The automatic controller is formed by that an automatic control is connected to an oxygen feeding pipeline, and a valve core is a sphere 4; the axial lines of openings (14, 13) of an oxygen inlet pipeline and an oxygen outlet pipeline in the position of the sphere on a valve body are crossed, and the opening 14 of the oxygen inlet pipeline is positioned below the opening 13 of the oxygen outlet pipeline; the sphere 4 is controlled by a compressive spring 3 in the valve body, and the spring force of the compressive spring is close to or equal to the stated excessive pressure of the oxygen in the oxygen bottle. In the process of using the oxygen bottle, so long as the pressure in the bottle is higher than the excessive pressure and the valve core is opened, the oxygen passes through a hole 5 to be provided for an electro-welding gun from the oxygen outlet end 8. When the pressure is lower than the excessive pressure, the valve core is closed.
Description
The utility model relates to a kind of oxygen cylinder overbottom pressure automatic controller, is contained on the oxygen cylinder ventilation channel, close automatically when reaching overbottom pressure, and be the oxygen cylinder safety protection device.
At the oxygen that fields such as technology gas welding (cutting) and medical treatment are used, the overwhelming majority is to use bottle oxugen to come oxygen supply.In order to guarantee in using the oxygen cylinder process, not sneak into inflammable gas, stipulated clearly that on working specification the oxygen in the bottle is forbidden to use up, should leave 0.1～0.2 MPa (1-2 kilograms per centimeter
2) residual pressure, fall to inject in the bottle to prevent inflammable gas, otherwise the generation that can cause a serious accident.At present, how to control residual pressure in the oxygen cylinder? generally all by grasping on operator's subjectivity, or rule of thumb control, but to the beginner has been exactly a difficult problem, often makes in the bottle residual pressure on the low side or use up, because the pressure of the bottled acetylene gas that is used with it at present can reach 0.8 MPa, be much higher than the working pressure of widely used acetylene producer (0.045～0.1 MPa) in the past, operator are in case error can make combustion gas inject in the oxygen cylinder, and consequence is dangerous.
The purpose of this utility model is to overcome shortcoming part in the above-mentioned prior art, and but automatic controller during the oxygen cylinder overbottom pressure power that can cut out automatically when providing a kind of oxygen cylinder in use to reach the regulation residual pressure can guarantee oxygen cylinder safety in use.
The purpose of this utility model can reach by the following technical programs: connect internally piloted valve on ventilation channel, spool is a spheroid, on the valve body in the spheroid place axes intersect into and out of the oxygen line portals, and the oxygen intake tube crossing is under the oxygen output pipe crossing; Spheroid is by compression spring control in the valve body, and its spring force is near the overbottom pressure of oxygen cylinder regulation.
Above-mentioned valve body is enterprising, oxygen output pipe crossing axis can be vertical, and the oxygen intake tube road down; Guide sleeve is arranged on the spheroid in the valve body, have voltage regulation screw stifled on the compression spring.
The utility model is compared above-mentioned prior art and had following effect: spool upper spring elastic force is near oxygen residual pressure in the oxygen cylinder that equals to stipulate, spool shutoff oxygen incoming road when pressure reaches residual pressure in the bottle, stop the generation of the on the low side or phenomenon used up of oxygen residual pressure in the bottle, provide safety measure for using oxygen cylinder.
Fig. 1 is the utility model complete section structural drawing.
Below in conjunction with accompanying drawing will the utility model is described in further detail:
Shown in accompanying drawing, connect on the oxygen cylinder ventilation channel one can open under the normal operating pressure in the bottle, closable internally piloted valve under the regulation residual pressure, spool is a spheroid 4, on the valve body in spheroid 4 places into and out of the oxygen line portals axes intersect of (13,14), and the oxygen intake tube crossing is under the oxygen output pipe crossing; Spheroid 4 is by 3 controls of compression spring in the valve body, and its spring force is near the residual pressure that equals to stipulate in the oxygen cylinder.
Above-mentioned valve body is enterprising, oxygen output pipe crossing (14,13) axis can be vertical, and oxygen intake tube crossing 14 should be down, make spheroid be subjected to the oxygen cylinder pressure direction upwards, gives upwards thrust of one of spheroid, and promptly oxygen pressure is opposite to the force direction of spheroid with spring.The prolongation pipeline of line portals (14,13) can design with oxygen supply pipe position in conjunction with actual, and oxygen intake tube terminal 6 can be connected with decompressor on the oxygen cylinder, and oxygen output pipe terminal 7 can be connected with the oxygen supply rubber hose coupling on the valve.For making the spheroid motion along orbiting motion, can be with guide sleeve 2 on the spheroid 4 in the valve body, in order to make spring 3 after date when using, still (the General provisions residual pressure is 0.1～0.2MPa) to its spring force near residual pressure, voltage regulation screw is stifled to be threaded with valve body and have on compression spring 3, and stifled 9 ends of screw are multi-arris body; Valve gap 11 is arranged on the plug, and packing ring 10 is arranged between valve body.After spring pressure mixes up, stamp lead sealing 12 then, can come into operation.
During work,,, reduce working life and reduce elastic force so spool 4 is unlikely the tension that spring 3 is pressed and makes spring fatigue under 2 effects of guide-localization sleeve because the pressure of oxygen is much higher than the elastic force of spring 3.In the oxygen using process, when the oxygen pressure in the bottle consumes to 0.2～0.1MPa, spool 4 is just closed oxygen channel automatically and is interrupted oxygen therapy work under the elastic force effect of spring 3, thereby guarantees that the interior residual pressure of oxygen cylinder is between the 0.1-0.2MPa of security regulations.Because possessing non-return function again on the structure of this oxygen cylinder overbottom pressure automatic controller, so, even the pressure of inflammable gas is big again, also can't pour in down a chimney in the oxygen cylinder.
