Abstract
The utility model discloses a U U tube manometer prevents injection apparatus, including U type pipe, container and feed liquor pipe and drain pipe, in the feed liquor guan shenyu container, it will to be equipped with the baffle in the container inner chamber the lower port of feed liquor pipe seals, and this baffle separates the container inner chamber for interconnected's epicoele and cavity of resorption, the baffle is relative with the liquid outlet of container, it has radial hole and container inner chamber intercommunication to distribute on the pipe wall of feed liquor pipe. The baffle of baffle for putting to one side. The utility model has the advantages of do not spray test solution.
Description
Technical field:
The utility model relates to a kind of measuring technology, particularly the manometric anti-jetting system of a kind of U-tube.
Background technology:
U-tube pressure gauge has the advantage of intuitive and convenient and is widely used, but its most distinct issues are, there is moment when significantly fluctuating in system under test (SUT) pressure, the measurement liquid of U-tube can spray, cause operating personnel's personal safety and contaminated environment, also need additional survey liquid and debugging efforts.
Summary of the invention:
The utility model object is a kind of manometric anti-jetting system of a kind of U-tube not spraying test fluid of design.
The technical solution of the utility model is, the manometric anti-jetting system of a kind of U-tube, comprise U-tube, container and feed tube thereof and drain pipe, it is characterized in that: described feed tube stretches in container, in container intracavity, be provided with baffle plate the lower port of described feed tube is closed, container intracavity is divided into the epicoele and cavity of resorption that interconnect by this baffle plate, and described baffle plate is relative with the liquid outlet of container, the tube wall of described feed tube is distributed with radial hole and is communicated with container intracavity.Described baffle plate is tilting baffle plate.
The utility model has the advantage of not spraying test fluid compared with the prior art.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model; Fig. 2 is the anti-injection structural representation of one of the present utility model, and Fig. 3 is the anti-injection structural representation of another kind of the present utility model; Fig. 4 is the third anti-injection structural representation of the present utility model.
Embodiment:
In conjunction with following embodiment, the utility model is elaborated, anti-jetting system 2 is cylindrical container, feed liquor escape pipe 3 is arranged at top, tube wall is distributed with radial hole 6, be provided with conical plate 5 in the lower port of this feed tube feed tube lower port is closed, make it export not to be communicated with cylindrical container, the cavity of cylindrical container is divided into two upper and lower cavitys interconnected by this conical plate, and anti-jetting system lower end is provided with the drain pipe 4 be connected with U-tube.The blowout prevention principle of this technical scheme is, when there is pressure increase in U-tube 1 system, test fluid in pipe enters in cylindrical container instantaneously, first conical plate is encountered, then rise to gradually in the cavity above conical plate, enter in feed tube by the radial hole on feed liquor tube wall, be greater than the liquid in U-tube when the volume of cylindrical container, and when reaching more than one times, just can avoid the generation (see Fig. 2) of spraying.
The technical scheme of another embodiment of the present utility model is, container 2 top of tubular is provided with feed tube 3, tube wall is distributed with radial hole 6 and cylindrical container inner space, a tilting baffle plate 5 is provided with in the lower outlet of this feed tube, above-mentioned feed tube lower port is closed by this baffle plate, this baffle plate is relative with the lower liquid outlet 4 of cylindrical container, cylindrical container inner chamber is separated into the epicoele and cavity of resorption that are interconnected by this baffle plate, above the side and baffle plate of feed tube, arrange another baffle plate 7, the lower end of this another baffle plate does not contact with baffle plate (see Fig. 3).
The anti-ejector principle of the second embodiment is, when the liquid of U-tube 1 upwards sprays, first baffle plate is encountered, after cavity below baffle plate is full of liquid, just be raised to the cavity above baffle plate, after being full of upper plenum, enter in feed tube by the radial hole on feed liquor tube wall, the effect of above-mentioned second baffle is little, can not arrange.As long as the liquid volume in the volumetric ratio U-tube of cylindrical container is large many, generally jet phenomenon would not be there is more than 50%.
The technical scheme of the 3rd embodiment is, anti-jetting system 2 is provided with feed tube 3, drain pipe 4, feed tube lower port is closed by dividing plate 5, and anti-liquid-jet device inner chamber is divided into two epicoeles and cavity of resorption interconnected, the tube wall of described feed tube is provided with radial hole 6 and is communicated with the epicoele of described anti-liquid-jet device.The anti-ejector principle of this 3rd embodiment is identical with the first two embodiment (see Fig. 4).
Prove by experiment: the volume of cylindrical container should be greater than U-tube liquid volume, the feed tube on cylindrical container top only has the radial hole on tube wall to be communicated with container intracavity, at container intracavity, baffle plate is set, container intracavity is separated into the upper and lower cavity be interconnected three conditions can avoid spraying, its baffle plate both can be tilting baffle plate, also can be horizontally disposed with, effect be without significant difference.
Claims (2)
1. the manometric anti-jetting system of U-tube, comprise U-tube, container and feed tube thereof and drain pipe, it is characterized in that: described feed tube stretches in container, in container intracavity, be provided with baffle plate the lower port of described feed tube is closed, container intracavity is divided into the epicoele and cavity of resorption that interconnect by this baffle plate, described baffle plate is relative with the liquid outlet of container, the tube wall of described feed tube is distributed with radial hole and is communicated with container intracavity.
