Abstract
The utility model provides a dedicated tool for the pressure test of pipe fittings. The dedicated tool comprises a plug cover plate, wherein a standard plug hole is formed on the inner side of the plug cover plate; a plurality of through-holes are formed on the plug cover plate, a plurality of through-holes are further formed on a pressing plate and connected with the through-holes of the plug cover plate via bolts equipped with nuts; a plug arranged in the through-hole of the plug cover plate comprises an inner sleeve and an outer sleeve, the inner sleeve is particularly a tapered body tapered from one end to the other end, and a tapered hole fitted with the inner sleeve is formed on the outer sleeve; threaded holes are formed at the large end and small end, the threaded hole at the large end is connected with the bolt on the pressing plate, and the threaded hole at the small end is equipped with bolts and nuts for tightly pressing the plug cover plate; and at least one sealing groove is formed on the outer wall of the inner sleeve and equipped with an O-shaped sealing ring. Accordingly, the dedicated tool of the utility model can guarantee that the sealing performance is good during the pressure test of the pipe fittings, ensure that the plug can be easily taken out, save the time for pressure tests and improve the operating efficiency.
Description
(1) technical field: the utility model relates to the special-purpose structure for pressure test of a kind of pipe fitting of pipe fitting pressure testing device, particularly tee pipe fitting.
(2) prior art: at present, the pressure-bearing pipe fitting must carry out the hydraulic testing by part, and the standard code pipe fitting has thousands of kinds, the difficult pressure testing of single support cut in the wherein threeway class pipe fitting, traditional pressure-measuring method is to install cushion rubber at bellmouth, inserts plug, with bolt with the fastening back pressure testing of plug.The greatest problem that traditional pressure-measuring method exists is that fastening bolt can not compress the seal gasket of plug and screw junction, and the pipe fitting of particularly big specification examination high pressure leaks from seal gasket, causes the pressure testing failure.Get to get off after the seal plug pressure testing besides, reason be the plug that inserts when the crush seal cushion rubber, bigger decrement and ratio of compression are arranged, the cushion rubber ball head is divided into flexible glue when adding design, support section is an ebonite, thus insert than being easier to, very difficult when extracting.
(3) summary of the invention: the purpose of this utility model is improved above shortcoming exactly.Good airproof performance when proposing a kind of pipe fitting pressure testing, plug takes out easily, saves the pressure testing time, the special-purpose structure for pressure test of the pipe fitting of increasing work efficiency.
The special-purpose structure for pressure test of the utility model pipe fitting, include the plug cover plate, plug cover plate inboard is provided with standard socket, has some through holes on the plug cover plate, also has some through holes on the pressing plate, be connected by bolt between pressing plate through hole and the plug cover plate through hole, be furnished with nut on the bolt, it is characterized in that: be provided with a plug in the through hole of plug cover plate, cover and overcoat in this plug includes, interior cover is a big little cone-shaped body
Overcoat has the bellmouth that matches with interior cover, and the stub end of interior cover and little head end have threaded hole, and the stub end threaded hole is connected with bolt on the pressing plate, and the threaded hole of little head end is furnished with the plug of compressing cover plate bolt and nut.
The special-purpose structure for pressure test of described pipe fitting is characterized in that: have at least one seal groove on the outer wall of inside race and be furnished with the O RunddichtringO.
The utility model is good airproof performance when the pipe fitting pressure testing, and plug takes out easily, saves the pressure testing time, increases work efficiency.
Principle of work:
The microcephaly is outside inwards because of major part to be installed in plug on the plug cover plate, and high sealing is tight more more for pressure during pressure testing, and plug can bear the above high pressure of 50MPA, therefore can not leak.Pressure testing releases high pressure after finishing, and unscrews the nut on the pressing plate, takes off bolt, when pressurizeing gradually, by the thrust of water the plug cover plate is released then.
