It dismantles the advantage being mounted on plug ontology 11 to be: being conveniently adjusted position of the limited block 10 on plug ontology 11.Limit
Handle 8 is provided between block 10 and end cap 5, handle 8 includes integrally formed handle body 81 and handle retainer 82, hand
Handle ontology 81 is located at the outside of sleeve 4, and handle retainer 82 is sleeved on plug ontology 11, presses handle sheet to 4 direction of sleeve
Body 81 can make the outer end of handle retainer 82 be upturned block on limited block 10, and handle retainer 82 is leaned on
The end cap 5 of one end pressing sleeve 4 of nearly handle body 81, so as to drive sleeve 4 and its retainer 42 to be bored to the swollen cylinder 3 of split-type
31 smaller diameter end direction of body section moves, until the retainer 42 at 4 block end of sleeve is separated with swollen 3 cone segments 31 of cylinder of split-type.
The effect that handle 8 is arranged is: very easily heat exchanger tube can be packed into plug casing 12, also will can very easily be changed
Heat pipe is removed out of plug casing 12 and the swollen cylinder 3 of split-type, to substantially increase the efficiency of the hydraulic pressure detection of heat exchanger tube.
In addition, the end of the plug ontology 11 outside sleeve 4 is connected with crossover sub 9, the structure of crossover sub 9 includes: to connect
Head ontology 91, one end of joint body 91 are provided with threaded connection hole 92, and threaded connection hole 92, which is screwed, to be connected to outside sleeve 4
The end of plug ontology 11, the other end of joint body 91 be provided with screw thread switching casing 93, screw thread transfer casing 93 be used for
Water pump is connected, and connection duct 94 is additionally provided in joint body 91, connection duct 94 is for casing 93 of transferring respectively with screw thread
It is connected with the fluid passage 13 in 92 inner core rod ontology 11 of threaded connection hole；The end of plug ontology 11 outside sleeve 4 is arranged
Fluted 111, groove 111 is interior for installing gasket, when offering through-hole on the gasket installed in groove 111, connection
Duct 94 can be connected with the fluid passage 13 in plug ontology 11；Through-hole is not set when the gasket installed in groove 111 is closed
When, the end of fluid passage 13 is closed in the outer plug ontology 11 of sleeve 4.
It is as follows in the step of installing pressure testing plug on heat exchanger tube: to press handle body 81, handle retainer to 4 direction of sleeve
82 outer end is upturned block on limited block 10, and handle retainer 82 presses end cap 5 close to one end of handle body 81,
To drive the retainer 42 at 4 block end of sleeve to move to swollen 3 cone segments of cylinder, the 31 smaller diameter end direction of split-type, until sleeve 4
The retainer 42 at block end is separated with swollen 3 cone segments 31 of cylinder of split-type, at this time stretches to heat exchanger tube in the swollen cylinder 3 of split-type,
Swollen 33 of the heat exchanger tube extruding swollen cylinder 3 of split-type is to stretch in plug casing 12, mounting groove 122 on 12 inner wall of plug casing
In sealing ring to seal against each other between the outer wall of heat exchanger tube and the inner wall of plug casing 12.Then release handle ontology 81,
Under the elastic force effect of spring 6, the retainer 42 at 4 block end of sleeve is closely clamped on the outer of the cone segments 31 of the swollen cylinder 3 of split-type
On wall, so that mutual swelling between the swollen cylinder 3 of split-type and heat exchanger tube, completes the installation of pressure testing plug in this way.
When pressure testing, heat exchanger tube is fixedly mounted on bracket, and installs a pressure test plug respectively at the both ends of heat exchanger tube
Head.One end of heat exchanger tube is water inlet end, and the other end is closed end.Plug in the pressure testing plug crossover sub 9 of heat exchanger tube water inlet end
The gasket for offering through-hole is installed in the groove 111 of the end of ontology 11, can also directly use sealing ring, connect in this way
Duct 94 is connected with the fluid passage 13 in plug ontology 11, the crossover sub 9 on the pressure testing plug of heat exchanger tube water inlet end with
Water pump is connected.Crossover sub on heat exchanger tube closed end pressure testing plug does not fill first temporarily.Water pump is started to work, and water is successively through changing
Connection duct 94, fluid passage 13 in heat pipe water inlet end pressure testing plug enter in heat exchanger tube, and the liquid at heat exchanger tube both ends is logical
Water in road 13 can also be entered in the admission chamber 41 at each end by the water outlet duct 14 at each end respectively, when heat exchanger tube closing is brought out
Heat exchange inner air tube drains water afterwards for a period of time, then loads onto the crossover sub of the pressure testing plug of heat exchanger tube closed end, exchanges heat
Gasket in the crossover sub at duct occlusion end in the groove of the end of plug ontology is closed not to set through-hole, in this way heat exchange duct occlusion
The end of fluid passage is closed in the pressure testing plug of end namely heat exchanger tube closed end is closed.Water, which keeps, enters to heat exchange
In pipe, the pressure in heat exchanger tube and in heat exchanger tube both ends admission chamber 41 constantly increases, the water in heat exchanger tube both ends admission chamber 41
Pressure is so that the block end of each end cap cylinder 4 all has and moves to the larger diameter end direction of the cone segments 31 of the swollen cylinder 3 of each end split-type
Trend, and hydraulic pressure is bigger, and this trend is stronger.Therefore, the hydraulic pressure in hydraulic pressure detection process, in every end intake antrum 41
Under double action with 6 elastic force of spring, the retainer 42 at every 4 block end of end cap cylinder even closer can be clamped on corresponding split-type
On the outer wall of the cone segments 31 of swollen cylinder 3, so that swelling is closer, more firm between the swollen cylinder 3 of the split-type at every end and heat exchanger tube
It leans on.
The present invention has the advantages that split-type is swollen, and cylinder 3 can firmly swelling be locked in plug casing 12 by heat exchanger tube when pressure testing
In, effectively ensure that hydraulic pressure detection efficiently quickly carries out, to substantially increase the working efficiency of heat exchanger tube hydraulic pressure detection.
