Abstract
The utility model relates to a leak detection device for corrugated hoses, which comprises an airtight tube, and sealing rubber rings arranged at the two ends of the airtight tube. One end of each sealing rubber ring is sleeved at the end portion of the airtight tube, and the periphery of the other end of the sealing rubber ring is provided with a hoop. The airtight tube is provided with a charge valve. When the device is in use, a corrugated hose is inserted in the device. The sealing rubber rings are just sleeved outside the steel hoops of the corrugated hose. Based on the cooperation of the hoops, the sealing connection of the corrugated hose with the device is realized. In this way, a closed space is formed between the outer surface of the corrugated hose and the inner surface of the leak detection device. Gas of a certain pressure is fed into the closed space through the charge valve and then the entire device is put in a water tank. Whether the leakage occurs to the corrugated hose or not can be observed through the two ends of the device. The device can be used for not only detecting the airtightness of welding beads, but also detecting the leakage phenomenon of a hose body. The device is simple and efficient to use, and is helpful for enterprises to better control the qualities of corrugated hoses. Therefore, the device has a broad market prospect.
Description
Technical field
The utility model relates to a kind of leakage detection apparatus, is specifically related to a kind of for detection of the bubble-tight device of corrugated flexible hose.
Background technology
Corrugated flexible hose is the vitals in the high-voltage switch gear hydraulic system, requires its pipe interior free from flaw, and welding bead does not have burr, pore, crackle.Corrugated flexible hose (as shown in Figure 1) comprises hose main body 1 and is wrapped in the outer woven wire 2 of hose main body 1, and hose main body 1 two ends are welded with stirrup 3, and stirrup 3 is used for fixing woven wire 2 on the one hand, is in order to be welded to connect flange on the other hand.As can be seen from Figure 1, the complex structure of corrugated flexible hose, the difficulty of therefore hunting leak is bigger, but if do not carry out leak test, will scrap in case find the whole parts of gas leakage.At present, for corrugated flexible hose welding bead 4, what adopt usually is dye penetrant inspection, and problem is that the foreign material that produce after the dye penetrant inspection are difficult to remove.And hose main body 1 external cause has woven wire 2 parcels can't detect especially.As seen, exploitation is fit to the leakage detection apparatus of corrugated flexible hose, has the urgent market demand.
Summary of the invention
The purpose of this utility model aims to provide a kind of corrugated flexible hose leakage detection apparatus.
Based on above-mentioned purpose, the utility model has been taked following technical scheme: the corrugated flexible hose leakage detection apparatus, comprise GT tube and the O-ring seal that is arranged on the GT tube two ends, and O-ring seal one end is enclosed within the GT tube end, and other end periphery is provided with clip; GT tube is provided with gas filling valve.
For further guaranteeing the sealing that is connected of O-ring seal and GT tube, the socket place of described O-ring seal and GT tube also is provided with clip.
Described clip is steel wire hoop.
Described GT tube is the PPR pipe.
The corrugated flexible hose leakage detection apparatus that the utility model provides is simple in structure, compact, be easy to processing, and production cost is low.During use, corrugated flexible hose is inserted wherein, O-ring seal is enclosed within outside the stirrup of corrugated flexible hose just, realizes being tightly connected under the assistance of clip.Thus, corrugated flexible hose outside surface and leakage detection apparatus inside surface have constituted a confined space.After gas filling valve charges into the gas of certain pressure, package unit is put into tank, can observe corrugated flexible hose from two ends and have or not gas leakage.Whether this device can not only detect the impermeability of welding bead, can also detect hose main body and leak gas, and is easy, efficient, can help enterprise to control the ripple hose quality well, has vast market prospect.
Description of drawings
Fig. 1 is the structural representation of corrugated flexible hose.
Fig. 2 is structural representation of the present utility model.
Embodiment
The corrugated flexible hose leakage detection apparatus as shown in Figure 2, comprises GT tube (PPR pipe) 5 and the O-ring seal 6 that is arranged on GT tube 5 two ends, and O-ring seal 6 one ends are enclosed within GT tube 5 ends, and socket place is provided with clip (steel wire hoop) 7; O-ring seal 6 other end peripheries also are provided with clip (steel wire hoop) 7; GT tube 5 is provided with gas filling valve 8.
When detecting, earlier corrugated flexible hose is put into said apparatus, O-ring seal 6 is enclosed within outside the stirrup 3 of corrugated flexible hose just, utilize clip 7 that both are sealed then.Charge into the air of 0.5MPa from gas filling valve 8 to device, the leakage detection apparatus that will assemble corrugated flexible hose to be detected then places tank, and whether observe from two-port has bubble to produce.If bubble is arranged, then indicate corrugated flexible hose gas leakage, if it is do not have, then qualified.
Corrugated flexible hose among Fig. 2 is corresponding with Fig. 1, and namely hose main body 1, woven wire 2, stirrup 3 and welding bead 4 have constituted corrugated flexible hose jointly.
