Abstract
The invention provides a pressure resistance detection device of a hollow pipe, which consists of a fixed seat device, an air and water inlet pipe and a sealing ring, wherein the sealing ring is a YX type dustproof sealing ring fixed in the fixed seat device, and the fixed seat device can move towards both sides. When the device does not work, the YX type dustproof sealing ring is not in contact with the outer circle surface of a steel pipe. When the device works, because of the effect of the internal pressure, the outer surface of the YX type dustproof ring is attached with the surface of a pipe element and the inner contact surface of the fixed seat device, and the higher the internal pressure is, the tighter the pasting effect with the surface is, so the air leakage possibility of the pressure resistance detection device does not exist.
Description
Technical field
The present invention relates to a kind of airtight test device, particularly steel pipe class pressure resistance detection device.
Background technology
Present industrial pipe fitting is produced and can't be tested to impermeability and water pressure resistance, the particularly resistance to pressure inspection of stainless-steel pipe, when processing without finishing, steel pipe must detect pipe fitting, as detect steel pipe and reach impermeability under the authorised pressure, then this pipe fitting is carried out finishing, as fail to reach standard, then need melt down processing again, so testing fixture needs the formed pipe fitting of roughing is detected, because roughing not line up is processed, the sealing of testing fixture then seals with the air packing line up, the difficulty of checking is bigger, existing producer generally adopts device shown in Figure 1 to detect, because being roughing, pipe fitting generates product, its mouth of pipe is irregularly shaped, it or not smooth flat, so to the packing washer well damage described in Fig. 1, need be to its frequent replacing, and when mouth of pipe degree of irregularity during greater than packing washer deformation degree, this pipe fitting then can't detect, be the pressurization detection owing to detect, the effect that the hydraulic means need provide corresponding pressure to reach sealing to top pressure closure in the pick-up unit, because the pressure that detects is bigger, hydraulic means pressure slowly increases, cause detection time long, pressure is big easy gas leakage or water.
Summary of the invention
The pressure resistance detection device of a kind of hollow tubular of the present invention, its purpose is to provide a kind of pick-up unit that can overcome the above problems, it adopts seal to contact sealing with cylindrical, avoided contacting with the mouth of pipe and caused the seal deformed damaged with seal, the seal that adopts is a YX type dust-proof seal ring, provide pressure and pipe internal pressure to interact thereby need not hydraulic means, structure is simpler, and testing process is safer.
The pressure resistance detection device of a kind of hollow tubular of the present invention, it is by fixation base structure 6, air inlet (water) pipe 1 and YX type dust-proof seal ring 3 are formed, YX type dust-proof seal ring is fixed in the fixation base structure 6, fixation base structure 6 can move to both sides, when device is not worked, YX type dust-proof seal ring does not contact with the steel pipe outer round surface, during device work because the internal pressure effect, make YX type dust-proof seal ring outside surface and pipe fitting surface and fixation base structure inner contact surface fit, big more its of internal pressure fitted closely more with the surface, do not exist the gas leakage may.
The present invention has simplified the structure of original testing fixture, need not hydraulic means, has better sealed pipe fitting inside, strengthened the reliability that detects, and O-ring seal does not have wearing and tearing in testing process, thereby has avoided frequent replacing O-ring seal.

Fig. 2 is the installation drawing of the pressure resistance detection device of a kind of hollow tubular of the present invention.
Fig. 3 is the pressure resistance detection device working condition figure of a kind of hollow tubular of the present invention.
Embodiment
The pressure resistance detection device of a kind of hollow tubular of the present invention, it is by fixation base structure 6, air inlet (water) pipe 1 and YX type dust-proof seal ring 3 are formed, as Fig. 2, YX type dust-proof seal ring is fixed in the fixation base structure 6, fixation base structure 6 can move to both sides, when device is not worked, YX type dust-proof seal ring does not contact with the steel pipe outer round surface, as Fig. 3, owing to the internal pressure effect, make YX type dust-proof seal ring outside surface and pipe fitting surface and fixation base structure inner contact surface fit during device work, big more its of internal pressure fitted closely more with the surface, do not exist the gas leakage may.
