Description
Technical field
This utility model relates to atomic absorption cover technical field, more particularly to a kind of height adjustable, the adjustable adjustable atomic absorption cover of air quantity.
Background technology
When laboratory does chromatography experiment, instrument and equipment often has high-temperature gas and discharges, and is therefore accomplished by a kind of atomic absorption cover corrosion-resistant, resistant to elevated temperatures, discharges with the high-temperature gas distributed by instrument.
Existing atomic absorption cover product, on market, many employing rustless steel square pipes are connected with horn mouth rustless steel fan housing, and stainless steel pipes is connected with outside airduct, carry out the discharge of high-temperature gas, but height and air quantity all cannot regulate.Owing to frequent instrument and equipment height is different, and effect is bad from instrument is too high to cause atomic absorption cover inlet scoop, or too low causes that equipment cannot be put into.Due to the difference according to equipment, hot air discharge amount is also different, and traditional atomic absorption cover cannot regulate air quantity, carries out the discharge of full blast amount, causes energy waste, or noise is bigger.
Summary of the invention
Technical problem for above-mentioned existence, this utility model purpose is: provide a kind of adjustable atomic absorption cover, namely achieves altitude mixture control by upper and lower two-section and fastening screw, by installing adjusting air valve in pipeline, realize air quantity can regulate, so substantially increase its practicality.
The technical solution of the utility model is:
A kind of adjustable atomic absorption cover, including exhaust duct and the suspended hood that is connected with exhaust duct, it is characterized in that, described exhaust duct includes cutting pipeline and lower tube road, described upper cutting pipeline and lower tube road is nested connections, described upper section pipeline and junction, lower tube road are provided with nut chute, and described nut chute two medial surface is provided with screw thread, described upper section pipeline and lower tube road are fixed by nut, and described exhaust duct lower end is provided with volume damper.
Preferably, described volume damper is arranged on the lower end in lower tube road, and described volume damper includes the air-valve fixing with axle, and described axle and air-valve are fixed on the lower end in lower tube road, and the other end of described air-valve is connected with air quantity adjusting nut by rocker arm shaft.
Preferably, described adjusting nut periphery is provided with damper box.
Compared with prior art, the utility model has the advantages that:
Adjustable atomic absorption cover is that atomic absorption cover is divided into upper and lower two-section, arranges locking nut in its junction, it is achieved upper and lower adjustable also can be locked.
In its pipeline, it is provided with air-valve, can need according to air quantity and be adjusted, it is achieved the adjustable atomic absorption cover of air quantity.
This atomic absorption cover, height adjustable, air quantity is adjustable.Very useful for experimenter, convenient.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further described:
Fig. 1 is the front view of the adjustable atomic absorption cover of this utility model；
Fig. 2 is the side sectional view of the adjustable atomic absorption cover of this utility model.
Wherein: 1, connection of air exhaust pipe, 2, above cut pipeline, 3, nut, 4, lower tube road, 5, nut chute, 6, nut passage, 7, suspended hood, 8, air quantity adjusting nut, 9, air-valve, 10, damper box, 11, air-valve axle, 12, rocker arm shaft.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with detailed description of the invention and with reference to accompanying drawing, this utility model is further described.It should be understood that these descriptions are illustrative of, and it is not intended to limit scope of the present utility model.Additionally, in the following description, eliminate the description to known features and technology, to avoid unnecessarily obscuring concept of the present utility model.
Embodiment:
As shown in Figure 1, 2, a kind of adjustable atomic absorption cover, including exhaust duct and the suspended hood 7 that is connected with exhaust duct, exhaust duct includes cutting pipeline 2 and lower tube road 4, upper cutting pipeline 2 and lower tube road 4 is nested connection, above cut pipeline 2 and junction, lower tube road 4 is provided with nut chute 5,5 liang of medial surface of nut chute are provided with screw thread, upper pipeline 2 and the lower tube road 4 of cutting is fixed by nut 3, and described exhaust duct lower end is provided with volume damper.When unclamping locking nut 3 with hands, lower tube road 4 can move up and down, and now the clamp nut 3 nut passage 6 in nut chute 5 can move up and down, and regulates to correct position and is fastened by clamp nut 3.
Suspended hood 7 is connected with lower tube road 4 full weld, is provided with volume damper in lower end, lower tube road 4.Figure gives the structure of a kind of volume damper.Volume damper includes the air-valve 9 fixing with axle 11, and axle 11 and air-valve 9 are fixed on the lower end in lower tube road 4, and the other end of air-valve 9 is connected with air quantity adjusting nut 8 by rocker arm shaft 12, and adjusting nut 8 periphery is provided with damper box 10.
Air-valve 9 can realize swinging under the effect of axle, so rotates air quantity adjusting nut 8 and makes air-valve 9 realize swinging, thus changing air quantity.
In use, unclamping locking nut 3, hand rest lives suspended hood 7, and is firmly up pushed away in lower tube road 4 or down pull out, and after reaching user correct position, tightens locking nut 3, has both achieved altitude mixture control.
When air quantity regulates, unclamp air quantity adjusting nut 8 and swung with hands, according to the scale in damper box 10, adjusting suitable air quantity, then tighten air quantity adjusting nut 8, both achieved the adjustment of air quantity.
To sum up, this atomic absorption cover simple in construction, it is achieved the up-down adjustment of suspended hood and the adjustment of air quantity.
It should be appreciated that above-mentioned detailed description of the invention of the present utility model is used only for exemplary illustration or explains principle of the present utility model, and do not constitute restriction of the present utility model.Therefore, any amendment of making when not necessarily departing from spirit and scope of the present utility model, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.Additionally, this utility model claims be intended to fall in the equivalents on scope and border or this scope and border whole change and modifications example.
