Abstract
The utility model belongs to the field of acetylene pressure reducer. An acetylene pressure reducer comprises a body which is provided with an air outlet pipeline and an air inlet pipeline; an air outlet pressure meter is communicated with the air outlet pipeline and the air inlet pipeline; a pressure adjusting valve is disposed in the body; and the air outlet pipeline is also provided with a one-way valve. The acetylene pressure reducer overcomes the defect of the prior art; when a tempering is caused by severe working environment or improper human operation, the pressure of the air outlet pipeline is greater than the pressure in a body cavity, and the one-way valve is closed by effect of a spring B, then the acetylene gas is interrupted, thereby ensuring safety in operation.
Description
Technical field
The utility model belongs to the acetylene regulator field.
Background technique
Acetylene regulator generally is the decompressor of bottled gas.When inlet pressure and rate of discharge change, guarantee that its outlet pressure keeps stable all the time.Because the gas cylinder internal pressure is higher; And gas welding and gas cutting are less with a use required pressure; So need come to reduce to low-pressure gas to the gas that is stored in the elevated pressures in the gas cylinder with decompressor, and should guarantee that required working pressure keeps steady state from start to finish.In a word, decompressor is that pressurized gas are reduced to low-pressure gas, and kept the pressure and the constant controlling device of stability of flow of output gas.
The body of acetylene regulator is to be processed by brass < HPb59-1 >.Form by component such as push rod, pressure adjusting spring, elastic film device, reduction valve.Be mainly used in acetylene gas is sent into gas welding, gas cutting operation point.When screwing pressure regulating screw, through pressure adjusting spring, elastic film, make reduction valve do opening and closing in various degree, regulate the decompression degree of bottled acetylene gas or stop air feed being used for.
When using acetylene regulator, when screwing adjusting screw clockwise, can back down reducing valve, acetylene gas just flows into low pressure chamber from the slit.Owing to acetylene gas expands in the low pressure chamber inner volume pressure is reduced, i.e. decompression.
Existing acetylene regulator is the single control mode of air-flow path, and control valve is installed in the centre of inlet, outlet circulation road; When work under bad environment or the improper airflow reflux that forces of manual operation, be prone to produce tempering phenomenon.In a single day tempering gets into decompressor and feeds the danger that acetylene cylinder will be blasted.
The model utility content
The utility model is intended to overcome the existing technology deficiency, and a kind of acetylene regulator is provided.
Acetylene regulator comprises main body 10, on main body, is provided with outlet pipe 1 and admission line 7, and the pressure gauge 8 of giving vent to anger is communicated with outlet pipe 1, and boost gauge 9 is communicated with admission line 7; Be provided with pressure regulator valve in the described main body 10; It is characterized in that: on outlet pipe, also be provided with one-way valve.
The utility model overcomes the existing technology deficiency, and when work under bad environment or manual operation is improper when causing tempering, outlet pipe air pressure is greater than the main cavity internal pressure, and one-way valve is closed under the effect of spring B, and acetylene gas interrupts, thereby has guaranteed handling safety.
Description of drawings
Fig. 1 is the utility model structural representation plan view, wherein, and 1 outlet pipe, 2 one-way valve spools, the stifled B in 3 location, 4 spring B, 5 seal rings, 6 cotter pins, 7 admission lines, 8 pressure gauges of giving vent to anger, 9 boost gauges; 10 main bodys.
Fig. 2 is the utility model structural representation plan view, wherein, and 1 outlet pipe, 2 one-way valve spools; The stifled B in 3 location, 4 spring B, 5 seal rings, 6 cotter pins; 7 admission lines, 10 main bodys, 11 pressure regulator valve pellets, 12 spring A, 13 spring film backing plates, 14 spring films; 15 pressure adjusting springs, 16 spring backing plates, 17 handles, the stifled A in 18 location.
Embodiment
Referring to Fig. 1, Fig. 2, acetylene regulator comprises main body 10, on main body, is provided with outlet pipe 1 and admission line 7, and the pressure gauge 8 of giving vent to anger is communicated with outlet pipe 1, and boost gauge 9 is communicated with admission line 7; Be provided with pressure regulator valve in the described main body 10; It is characterized in that: on outlet pipe, also be provided with one-way valve.
Described pressure regulator valve is laminated by the stifled A18 in location that is located at handle 17 in main body one end, spring backing plate 16, pressure adjusting spring 15, spring film backing plate 13, spring film 14, adjusting pressuring valve core 11, spring A12, the sealing main body the other end in proper order to be formed.
Described one-way valve is included in the valve body of one section formation of intercepting on the outlet pipe, and the stifled B3 in the location of one-way valve spool 2, spring B 4, closed valve inserts wherein in proper order.
The outer end of described one-way valve spool 2 is provided with stopping pin 6, is used for the location, and the one-way valve spool is deviate from when preventing that air-flow is excessive.
Be provided with seal ring 5 between described one-way valve spool 2 and the valve body.Be used to increase the encapsulation of one-way valve.
Under the operating mode, the gas cylinder acetylene gas gets into pressure gauge 9 through admission line 7 and arrives spring A12 surrounding space; When handle 17 rotations stress on spring backing plate 16; Conduct in pressure adjusting spring 15, spring film backing plate 13, spring film 14, affact adjusting pressuring valve core 11 and make it to open; Acetylene gas is pressed in getting into and producing in main body 10 chambeies; Outwards expand and make spring film 14 pressurizeds, reverse interlock spring film backing plate 13 make pressure adjusting spring 15 pressurized displacements; Adjusting pressuring valve core 11 reverses under spring A12 effect, makes adjusting pressuring valve core 11 places, and it is that air pressure tolerance changes thereupon that ventilation space changes, and when the gas output in the outlet pipe 1 strengthened, main body 10 cavity pressures reduced, each parts recovery ortho states.Above flow process reciprocating action just can provide stable acetylene gas by required.
The effect of one-way valve shows: when acetylene gas pressure in the main cavity during greater than the outlet pipe external pressure, one-way valve is opened; Acetylene gas leads to the operation point of outlet pipe end outside; And open automatically according to the gas consumption size.When work under bad environment or manual operation is improper when causing tempering, outlet pipe air pressure is greater than the main cavity internal pressure, and one-way valve is closed down in spring B 4 effects, the acetylene gas interruption.
