Abstract
The utility model discloses a bellows gas circuit air supplement unit, include and bellows inner wall and sizing cover outer wall between the intercommunication first air inlet pipeline to and overlap the inside second air inlet pipeline that communicates with the sizing, it has the proportional valve to establish ties on the first air inlet pipeline, it has one -way aeration valve and exhaust cleat valve still to connect in parallel on the first air inlet pipeline. The utility model discloses a bellows gas circuit air supplement unit sets up in the bellows production line, in the middle of the production and processing process of bellows, be suitable for atmospheric pressure if the atmospheric pressure of proportional valve is less than production, open one -way aeration valve under the effect of bellows outer wall negative pressure and sizing cover negative pressure, can play the effect of stabilizing atmospheric pressure, make the finish of bellows inside and outside wall improve greatly, and then improved product quality and improved production efficiency.
Description
Technical field
This utility model relates to a kind of tubing and produces equipment, particularly to a kind of corrugated tube gas circuit making-up air device.
Background technology
At present, in the middle of the production process of corrugated tube, corrugated tube interbedded gas typically uses air pressure rule of three to pressurize
Blowing method is transported between the inwall of corrugated tube and outer wall, but due to the fluctuation of whole gas circuit air pressure, can make
Become the pressurization air pressure fluctuation of air pressure proportioning valve, thus cause corrugated tube inwall that corrugation-like depressions and outer wall occur
The fullest, the situations such as waste product even occur.
Utility model content
For solving above-mentioned technical problem, the utility model discloses a kind of corrugated tube gas circuit making-up air device, including
The first air inlet pipeline connected with between corrugated tube inwall and calibration sleeve outer wall, and connect with calibration sleeve inside
The second air inlet pipeline, described first air inlet pipeline is in series with proportioning valve, on described first air inlet pipeline also
It is parallel with one-way gas-compensating valve and aerofluxus angle pedestal valve.
The beneficial effects of the utility model are:
Corrugated tube gas circuit making-up air device of the present utility model is arranged in corrugated tube production line, in the life of corrugated tube
In the middle of the product course of processing, if the air pressure of proportioning valve less than produce be suitable for air pressure, corrugated tube outer wall negative pressure with
And open one-way gas-compensating valve under the effect of calibration sleeve negative pressure, it is possible to play the effect of stable air pressure, make corrugated tube
The surface smoothness of inside and outside wall is greatly improved, and then improves product quality and improve production efficiency.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme in this utility model embodiment, below will be to institute in embodiment
The accompanying drawing used is needed to be briefly described, it should be apparent that, the accompanying drawing in describing below is only this practicality
Some novel embodiments, for those of ordinary skill in the art, are not paying creative work
Under premise, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is structure principle chart of the present utility model.
Labelling in figure: 1-proportioning valve；2-one-way gas-compensating valve；3-aerofluxus angle pedestal valve；4-corrugated tube；5-calibration sleeve.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the technical side in this utility model embodiment
Case is clearly and completely described, it is clear that described embodiment is only that this utility model part is real
Execute example rather than whole embodiments.
As it is shown in figure 1, a kind of corrugated tube gas circuit making-up air device, including with corrugated tube 4 inwall and calibration sleeve 5
First air inlet pipeline of connection between outer wall, and second air inlet pipeline that connect internal with calibration sleeve 5, the
It is in series with proportioning valve 1 on one air inlet pipeline, the first air inlet pipeline is also parallel with one-way gas-compensating valve 2 and aerofluxus
Angle pedestal valve 3.
Corrugated tube gas circuit making-up air device of the present utility model is arranged in corrugated tube production line, in the life of corrugated tube
In the middle of the product course of processing, if the air pressure of proportioning valve 1 is suitable for air pressure, in corrugated tube outer wall negative pressure less than producing
And under the effect of calibration sleeve negative pressure, open one-way gas-compensating valve 2, it is possible to play the effect of stable air pressure, make ripple
The surface smoothness of pipe inside and outside wall is greatly improved, and then improves product quality and improve production efficiency.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model,
All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all
Within protection domain of the present utility model should be included in.
