Survey means efficiency is low, and particularly girth joint is said, this detection means is not suitable with, it is therefore desirable to provide a kind of novel detection
Device is to carry out leak water detdction.
Utility model content
The purpose of this utility model is to be directed to technological deficiency in the prior art, and provides a kind of steel pipe seam and test leakage
Detection device.
Technical solution is used by realize the purpose of this utility model：
A kind of steel pipe seam tests device for detecting leakage, including being used to stretch by be oppositely arranged two of Driven by Hydraulic Cylinder respectively
The seal disc in sealing contact with steel pipe inner wall in steel pipe is formed with annular groove, the ring on the outer circumference surface of the seal disc
Cricoid inflatable rubber seal tape is installed, the gas tube of the rubber seal band connection is from the seal disc in connected in star
Lateral surface on draw in the mounting groove that is formed, have charge valve on the gas tube；The disk of one seal disc is equipped with
The water injection hole of water filling in the confined space formed between seal disc and steel pipe to two is equipped with water injection pipe in the water injection hole,
Water injection valve is installed on the water injection pipe.
The seal disc is connected by drive rod with the hydraulic cylinder.
The hydraulic cylinder is fixed in hydraulic pressure cylinder seat, and the hydraulic pressure cylinder seat is fixed on landing slab, the landing slab
On have leak observe slot.
The utility model is extend by two seal discs in steel pipe, after steel duct is formed a sealing space, is led to
Gas overcharging is heaved after being inflated using rubber seal tape to rubber seal tape, after the internal face tight seal for making seal disc and steel pipe,
By water injection hole into sealing space water filling pressurize, then by observation be located at sealing space in girth joint whether leak, behaviour
It is quick to make convenient and detection, has great importance.
Description of the drawings
Fig. 1 is the structure diagram that steel pipe seam tests device for detecting leakage；
Fig. 2 is scheme of installation of the blanket gas band on seal disc；
Fig. 3 is the front view of a seal disc.
Specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
Referring to shown in Fig. 1-3, a kind of steel pipe seam tests device for detecting leakage, including being set relatively by what hydraulic cylinder 3 drove respectively
Put for stretching into two seal discs in sealing contact with steel pipe inner wall in steel pipe 9, i.e. the first seal disc 1 and the second seal disc 2,
Annular groove 11 is formed on the outer circumference surface of the seal disc, cricoid inflatable rubber is installed in the annular groove
Band 12 is drawn in the mounting groove 22 formed on the lateral surface of the 13 self sealss disk of gas tube of the rubber seal band connection,
There is charge valve 14 on the gas tube；The disk of one seal disc is equipped with what is formed between seal disc and steel pipe to two
The water injection hole 21 of water filling in confined space is equipped with water injection pipe 16 in the water injection hole, water injection valve is equipped on the water injection pipe
17。
During work, the water injection pipe can be located at by the water pump 18 of pipeline connection, water pump 18 in water tank 19, pass through water pump
18 to sealing space between two seal discs and steel pipe 9 injection pressure (hydraulic) water, with detect the girth joint 10 on steel pipe whether leak.
The seal disc is steel disk, and the water injection hole is threadedly coupled with water injection pipe, the gas tube and rubber seal tape phase
Connection, for being inflated into rubber seal tape, and draws in self installation slot 22.
During work, the gas tube 13 of the rubber seal band connection can be connected to air pump 15 with transtracheal, will by air pump 15
Air squeezes into rubber seal tape, heaves rubber seal tape, is pressed into contact with the internal face of steel pipe, and realizes the effect of sealing.
Wherein, the seal disc is connected by the drive rod 20 of welding with the hydraulic cylinder.
Wherein, the hydraulic cylinder is integrally fixed in vertical hydraulic pressure cylinder seat 4, and the hydraulic pressure cylinder seat installation passes through its bottom plate 6
To there is bolt 7 to be fixed on landing slab 100, the both sides of vertical hydraulic pressure cylinder seat 4, which have, strengthens side plate 5, fixes and connects with the bottom plate 6
It connects, there is leak to observe slot 8 on the landing slab, when boxing is sewed with leak, leak observation slot 8 can be flowed to, pass through observation
The leak observation slot 8 whether have water, it can be determined that the soldered of steel pipe whether leak.
The utility model is extend by two seal discs in steel pipe, after steel duct is formed a sealing space, is led to
Gas overcharging is heaved after being inflated using rubber seal tape to rubber seal tape, after the internal face tight seal for making seal disc and steel pipe,
By water injection hole into sealing space water filling pressurize, then by observation be located at sealing space in girth joint 10 whether leak,
Easy to operate and detection is quick, has great importance.
The above is only the preferred embodiment of the utility model, it is noted that for the general of the art
For logical technical staff, under the premise of the utility model principle is not departed from, several improvements and modifications can also be made, these change
The scope of protection of the utility model is also should be regarded as into retouching.
