Abstract
The utility model relates to an air supply protective device, in particular to an air supply protective device used for production of gap block materials. The air supply protective device comprises a gas producing device; and the gas producing device is orderly connected with an inverted valve, a compressor, a pressure switch, a gas storage inverted valve, a gas storage tank, a reducing valve, an electromagnetic valve, a leaving air inverted valve, a ball valve, a flowmeter and an air use station through a connecting pipe; and in the same time, the leaving air inverted valve and the ball valve are also connected with the gas producing device. The air supply protective device has the advantages that in case of power cut, gas producing equipment failure or short repair and maintenance, protective gas is still used for production for some time, thereby ensuring that the produced workpiece or materials can be effectively protected.
Description
Technical field
The utility model relates to gas supply protecting device, in particular for the gas supply protecting device of bush material production.
Technical background
In the industrial production, many places will be protected with gas.Such as, when bush material carries out high temperature sintering in sintering furnace, need the gaseous mixture of logical nitrogen and hydrogen to protect gas in the sintering furnace, oxidation takes place in sintering furnace to prevent bush material.Nitrogen is supplied with by nitrogen making machine.In production in the past, when having a power failure suddenly, nitrogen making machine can not quit work because there being electricity, when perhaps breaking down suddenly owing to nitrogen making machine, and nitrogen making machine stop supplies nitrogen then.Oxidation can take place because protective gas is not enough in bush material in the sintering furnace of high temperature, cause scrapping of material, causes the loss of economy and property.In addition, when nitrogen making machine need carry out of short duration maintenance, whole sintered production line will stop in advance, just can shut down and maintain after waiting material to come out of the stove, and influenced production efficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of gas supply protecting device, still has gas to supply with when making system gas equipment because of power failure or fault and uses, and is not oxidized to guarantee the material in the sintering furnace.
Technical solution adopted in the utility model is: it is to be taken into account gas using station and link to each other with check valve, pressure place machine, pressure switch, gas storage check valve, air accumulator, pressure-reducing valve, magnetic valve, outgassing nonreturn valve, ball valve, flow successively by connecting pipe by system gas equipment; Simultaneously outgassing nonreturn valve and ball valve also link to each other with system gas equipment form.
Usefulness of the present utility model is: still have the protective gas supply to produce use a period of time when having a power failure or making when the gas equipment fault maybe needs to carry out of short duration (in 2 hours) maintenance, maintenance, can be effectively protected to guarantee workpiece or the material produced.
Description of drawings
Fig. 1 is the utility model schematic diagram
Wherein: 1, system gas equipment 2, connecting pipe 3, outgassing nonreturn valve 4, air accumulator 5, safety valve 6, Pressure gauge 7, check valve 8, pressure place machine 9, pressure switch 10, gas storage check valve 11, blowoff valve 12, gas using station 13, pressure-reducing valve 14, magnetic valve 15, ball valve 16, flowmeter
The specific embodiment
Be illustrated in figure 1 as the utility model schematic diagram.It is to be linked to each other with check valve 7, pressure place machine 8, pressure switch 9, gas storage check valve 10, air accumulator 4, pressure-reducing valve 13, magnetic valve 14, outgassing nonreturn valve 3, ball valve 15, flowmeter 16 and gas using station 12 successively by connecting pipe 2 by system gas equipment 1; Simultaneously outgassing nonreturn valve 3 and ball valve 15 also link to each other with system gas equipment 1 form.
Operation principle of the present utility model is: under normal working condition, the protective gas that system gas equipment 1 produces is directly supplied with gas using station 12 by ball valve 15, flowmeter 16 and is used; Simultaneously, inflate to air accumulator 4, make in the air accumulator 4 and store protective gas, maybe need to carry out of short duration maintenance, use when maintaining to guarantee to have a power failure or make gas equipment 1 fault by pressing place machine 8.
The operation principle of gas replenishment process of the present utility model is: Pressure gauge 6 is installed on the air accumulator 4; be used to measure the pressure of air accumulator 4; close when pressure switch 9 is set the pressure of 1.0Mp, open during the pressure of 0.5Mp; when the pressure of air accumulator 4 during less than 0.5Mp, pressure switch 9 is opened, and presses place machine 8 that the protective gas that system gas equipment 1 produces is pressed onto in the air accumulator 4; inflate; when the pressure of air accumulator 4 reached 1.0Mp, pressure switch 9 was closed, and pressed place machine 8 to stop inflation in air accumulator 4.
The utility model have a power failure system gas equipment 1 fault or need repairing, operation principle when maintaining is: owing to be connected to power supply on the magnetic valve 14, during energising, inhale piece and held, magnetic valve 14 cuts out; When having a power failure, the suction piece of magnetic valve 14 is flicked, and magnetic valve 14 is opened, and the protective gas that stores in the air accumulator 4 is supplied with gas using station 12 and used by pressure-reducing valve 13, magnetic valve 14, outgassing nonreturn valve 3.And when the system gas equipment 1 fault or need repairing, when maintaining; available manual method is cut off the power supply of magnetic valve 14; so that the suction piece of magnetic valve 14 is flicked; magnetic valve 14 is opened, and the protective gas that stores in the air accumulator 4 is supplied with gas using station 12 and used by pressure-reducing valve 13, magnetic valve 14, outgassing nonreturn valve 3.
The operational time of protective gas that stores in the air accumulator 4 is by the volume and the gas consumption decision of air accumulator 4.The effect of the utility model pressure-reducing valve 13 is according to the gas consumption of production line, to adjust the size of pressure-reducing valve 13 pressure.
