In addition, for the nitrogen filling device, the structure is simple, the cost is low, the reliability is high, the modification to the existing liquid filling machine in the market is convenient and the market prospect is great.
Description
Technical field
The utility model relates to a kind of protected against explosion liquid-filling machine nitrogen charging device, belongs to liquid form product auto-filling field.
Background technology
The protected against explosion liquid-filling machine is a specialized equipment of realizing the liquid form product auto-filling, can be widely used in industries such as oil, chemical industry.In fields such as oil, chemical industry, pigment, paint, the chemical property of a lot of liquid form products is inflammable, explosive, when carrying out can at present, if in the can bucket air is arranged, can cause chemical reaction, the quality of product be had certain influence, even also may produce blast.This just need come out the air displacement in the can bucket when the liquid form product auto-filling, carries out quantitative filling afterwards again.Nitrogen is cheap, and chemical inertness is good, and produces conveniently, and energy-conservation, safety is used to the air in the displacement can bucket in filling liquid, usually to reach explosion-proof purpose.
The utility model content
The utility model has designed a kind of protected against explosion liquid-filling machine nitrogen charging device, the technical matters of its solution is: in present field of petrochemical industry, a lot of inflammable and explosive liquid form products are in auto-filling, if there is air can cause chemical reaction in the can bucket, influence product design even set off an explosion, therefore must guarantee the nitrogen charging device quantitative filling that the air displacement in the can bucket can be come out to carry out again.
For solving above technical matters, the utility model has adopted following scheme: a kind of protected against explosion liquid-filling machine nitrogen charging device comprises: check valve, air operated reversing valve, gas source triplet and tracheae.The inlet of gas source triplet is connected on on-the-spot nitrogen pipeline or the nitrogen pot by first tracheae, the outlet of gas source triplet is connected to the inlet of air operated reversing valve by second tracheae, the outlet of air operated reversing valve is connected to the inlet of check valve by the 3rd tracheae, and the outlet of check valve is connected to the air pipe interface of liquid-filling machine spray gun middle and upper part by the 4th tracheae.During nitrogen charging device work, check valve can prevent that filling liquid from refluxing to nitrogen charging device, what the opening and closing of air operated reversing valve control nitrogen charging device, source of the gas three siamesed effects were to adjust nitrogen charging device fills nitrogen pressure, and tracheae then requires to have good anti-corrosion.
This utility model has following beneficial effect: by adopting this protected against explosion liquid-filling machine nitrogen charging device, utilizing liquid-filling machine liquid towards product in the process of row auto-filling, but actv. comes out the air in the can bucket with nitrogen replacement, and by connecting a check valve, avoided filling liquid to reflux, safety and production has been had very big benefit to nitrogen charging device.In addition, that this nitrogen charging device has is simple in structure, cost is low, high reliability features, convenient, simple, reliable to the transformation of the existing liquid-filling machine in market, has vast market prospect in future.

The specific embodiment
Below in conjunction with Fig. 1 and Fig. 2, the utility model is described further:
As shown in Figure 1, an air pipe interface 10 is installed in middle and upper part at bottle placer spray gun 9, connect the outlet of check valve 1 by the 4th tracheae 7, the inlet of check valve 1 is connected to the outlet of air operated reversing valve 2 by the 3rd tracheae 6, the inlet of air operated reversing valve 2 is connected to the outlet of gas source triplet 3 by second tracheae 5, the inlet of gas source triplet 3 connects on on-the-spot nitrogen pipeline 8 or the nitrogen pot by first tracheae 4, thereby connects into whole nitrogen charging device.During work; bottle placer spray gun 9 stretches in the can bucket; Pneumatic unidirectional valve 2 is opened; nitrogen gas pressure is adjusted the back by check valve 1 by gas source triplet 3; be injected in the can bucket through tracheae and spray gun; after after a while, the air in the bucket is come out with nitrogen replacement, carry out quantitative filling again, can protect and play explosion-proof purpose the chemical quality of the liquid material of can.
Fig. 2 is the structural representation of described check valve 1, and in the utility model, check valve 1 is a critical component, and it mainly comprises following parts: valve body 11, nut 12, stage clip 13, spool 14.1 of check valve allows air-flow to pass through in one direction, then closes fully in the opposite direction, thereby plays the effect of avoiding filling liquid to reflux to nitrogen charging device.Its concrete principle of work is: after check valve 1 left side admission port then adds air pressure, act on that atmospheric pressure on the spool 14 overcomes spring force and friction is opened spool 14, make turnover gas connect, air-flow then flows to the right mobile forward flow that is called then from a left side.If air extractor duct on check valve 1 right side then adds air pressure, the turnover flow of QI being obstructed, promptly air-flow can not counter-flow.In addition, in filling the nitrogen process, for guarantee air-flow from admission port to the air extractor duct stationary flow, should between admission port and air extractor duct, keep certain difference of pressure, make valve remain on the open position, this difference of pressure is adjusted by gas source triplet 3.
Through with present known technology in the comparison done of the research institute of many similar technical schemes, prove that this protected against explosion liquid-filling machine nitrogen charging device that the utility model takes is the most feasible also most economical.The utlity model has simple in structure, cost is low, high reliability features, and is also very convenient to the transformation of the existing liquid-filling machine in market, has vast market prospect
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obvious realization of the present utility model is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or design of the present utility model and technical scheme are directly applied to other occasion without improving, all in protection domain of the present utility model.
