Abstract
This utility model relates to a kind of checking motion, the especially float-ball type fluid column checking motion in differential manometer, including glass tubing 3, seal nipple 1, ball float 2, seal nipple 1 is arranged on glass tubing 3 top, is provided with through hole, it is provided with seal groove near glass tubing side, ball float is positioned in glass tubing, and its density is less than the density of liquid in glass tubing, and diameter is less than, diameter glass tube, and more than seal nipple 1 through-hole diameter.The structure that when this utility model can effectively prevent pressure overload, in fluid column, liquid overflows from top, this simple in construction, effect is obvious.
Description
Technical field
The present invention relates to the float-ball type fluid column checking motion in a kind of checking motion, especially differential manometer, belong to test neck
Territory.
Background technology
The fluid column pattern that differential manometer is common at present is the whole open unshielded structure in top and uses pipe joint, this pressure reduction
Pipeline liquid outflow during meter overload, it is impossible to play the effect preventing liquid from overflowing, i.e. " erosion control " effect from top.Differential manometer is filled out
The working media filled may be for liquid such as water, ethanol, oil, dibutyl esters, after causing liquid spill when pressure overload, and on the one hand meeting
Cause cleaning inconvenience, environmental pollution even potential safety hazard；On the other hand, also need to after spilling again install liquid additional, cause and make
With inconvenience.
Summary of the invention
The present invention provides a kind of structure that when can effectively prevent pressure overload, in fluid column, liquid overflows, i.e. float-ball type from top
Fluid column checking motion, this simple in construction, effect is obvious.
The technical scheme that the present invention takes is: a kind of float-ball type fluid column checking motion, including glass tubing 3, seal nipple 1,
Ball float 2, seal nipple 1 is arranged on glass tubing 3 top, is provided with through hole, is provided with seal groove near glass tubing side, and ball float 2 is positioned at
In glass tubing 3, its density is less than the density of liquid in glass tubing, and diameter is less than diameter glass tube, and more than seal nipple 1 through hole
Diameter.
Further, it is tapered bottom above-mentioned seal groove.
Advantageous Effects: provide a kind of structure that in fluid column, liquid overflows when effectively preventing pressure overload from top, should
Simple in construction, effect is obvious.
Accompanying drawing explanation
Fig. 1 is 1-seal nipple；2-ball float；3-glass tubing；4-liquid；
Fig. 2 is the enlarged drawing in Fig. 1 at seal nipple.
Detailed description of the invention
Below in conjunction with detailed description accompanying drawing, the present invention is described in further detail.
A kind of float-ball type fluid column checking motion, including glass tubing 3, seal nipple 1, ball float 2, seal nipple 1 is arranged on glass
Glass pipe 3 top, is provided with through hole, is provided with seal groove near glass tubing side, and ball float is positioned in glass tubing, and its density is less than glass tubing
The density of middle liquid, as shown in Figure 1.
When normally using, after experiencing pressure bottom differential manometer, in fluid column, liquid rises, and drives ball float to float, the most permissible
By fluid level scale interpretation force value.When pressure continues to increase to maximum, now liquid level rises to glass tubing top, and floats
Ball 2 and seal nipple 1 through hole agree with generation and seal, and liquid level will be stoped to continue to rise, thus realize preventing when pressure continues to rise
The effect that during pressure overload, liquid overflows from fluid column top, as shown in Figure 2.
In order to make sealing effectiveness more preferable, taper can will be set to bottom seal nipple 1 or other contribute to guiding ball float
The shape of laminating through hole.
Ball float can float over liquid level top, it is possible to plays the effect of instruction liquid level.
Present configuration is simple, is skillfully constructed, is not readily conceivable that, can be not only used for differential manometer, it is also possible to is used for needing
Carry other occasions of protection.
Claims (2)
1. a float-ball type fluid column checking motion, it is characterised in that: include glass tubing (3), seal nipple (1), ball float (2), close
