Abstract
The utility model discloses a kind of lifting sleeping pillow pressure test pipe line shock-absorbing denoising device device, which connects and composes air supply channel by airline hose and inflatable pillow.Pressure test pipeline one end is connect with pressure switch, and the other end is connect with air supply channel.Install a choke fitting additional on pressure test pipeline, the throttle diameter of choke fitting is a few micrometers to some tens of pm.One tee pipe fitting is housed on airline hose, pressure test pipeline enters tee pipe fitting by sealing orifice, and enters in inflatable pillow pillow by airline hose.The beneficial effects of the utility model are: the utility model by a variety of dampings and noise reduction technology means, prevents and eliminates the vibration and noise of the generation in equipment running process in links.It ensure that equipment runs smoothly.
Description
Technical field
The utility model relates to a kind of lifting sleeping pillow pressure test pipe line shock-absorbing denoising devices.
Background technique
Damping noise reduction at present is the Research Emphasis of inflated lifting sleeping pillow, generated vibration and noise in equipment operation
It is mainly derived from inflation system, since vibration and noise derives from whole system, so all routes and equipment in the system
It requires to be optimized in earnest and improved, be minimized so that vibration and noise be made to realize, although the work one of this respect at present
It is not interrupted directly, but still has a large amount of research to need to continue.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of lifting sleeping pillow pressure test pipe line shock-absorbing noise reductions
There is low noise, performance to stablize, use comfortable, compact-sized advantage for device, the device.
The utility model uses following technical scheme: the device includes the control device pressure of inflatable pillow, inflator pump, inflator pump
Power switch, inflator pump connect and compose air supply channel by airline hose and inflatable pillow.Pressure test pipeline one end and pressure switch
Connection, the other end are connect with air supply channel.Install a choke fitting, the throttle diameter of choke fitting additional on pressure test pipeline
It is a few micrometers to some tens of pm.
One tee pipe fitting is housed on airline hose, pressure test pipeline enters tee pipe fitting by sealing orifice, and
Entered in inflatable pillow pillow by airline hose.
The working principle of the utility model is: pressure test pipeline throttling set can control air-flow and enter pressure switch
Throughput is greatly reduced the wave crest of air-pump inflating air-flow, reduces the high and low variation of wave crest, trough, makes pressure switch one end
The steady ascending, descending of gas pressure.By adjusting the pore size of this throttle orifice, the fluctuation range of air-flow wave crest, trough is limited, is disappeared
The noise and electric spark generated in addition to the high-frequency switching movement of pressure switch caused by air-flow fluctuation and air pump.In band
Have in the aeration circuit of gas cell, when throttling set throttle orifice aperture reaches a few micrometers, the air pressure of pressure switch one end can be made
Delay a period of time reaches the air pressure of air pump, air bag one end.When the air pressure of pressure switch reaches setting value and controls disconnection inflation
When circuit, the air pressure of inflator pump and air bag one end alreadys exceed the setting value of pressure switch, so this throttling set plays and prolongs
When the effect that disconnects.Since actually final air pressure is higher than setting value for inflation system, effectively avoid since inflation system leaks
Noise and electric spark brought by gas bring pressure switch and its air pump frequent starting of control.
The beneficial effects of the utility model are: the utility model by a variety of dampings and noise reduction technology means, prevents and disappears
In addition to the vibration and noise of the generation in equipment running process in links.It ensure that equipment runs smoothly.
Detailed description of the invention
The utility model is described in detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the partial enlarged view of Fig. 1.
Figure label:
1, inflatable pillow 2, inflator pump 3, pressure switch 4, pressure test pipeline 5, choke fitting
6, airline hose 7, tee pipe fitting.
Specific embodiment
As shown in Figure 1 and Figure 2, which includes the control device pressure switch 3 of inflatable pillow 1, inflator pump 2, inflator pump 2, is filled
Air pump 2 connects and composes air supply channel by airline hose 6 and inflatable pillow 1.4 one end of pressure test pipeline is connect with pressure switch 3,
The other end is connect with air supply channel.Install a choke fitting 5 additional on pressure test pipeline 4, the throttle diameter of choke fitting 5 is
A few micrometers to some tens of pm.
One tee pipe fitting 7 is housed on airline hose 6, pressure test pipeline 4 enters tee pipe fitting by sealing orifice
4, and entered in 1 pillow of inflatable pillow by airline hose 6.
