When 501 welding angle of branch mouth pipe has deviation, bottom plate 408 just can make floating adjustment by extruding silicagel pad, finely tune sealing performance
The angle direction of mechanism for testing 3, adapts to the angular deviation of branch mouth pipe 501.
During test, referring to Fig. 6 to Figure 10, first three-way connection 5 is entered in cylinder 201 from 202 sidesway of branch mouth pipe locating slot, is propped up
Mouth pipe is moved to innermost end positioning along branch mouth pipe locating slot 202；According to 5 model of three-way connection, gag lever post upper limit nut is adjusted
Position, that is, the push position of sealing performance testing machine structure 3 is set, support plate driving mechanism 402 pushes limiting plate 403 and moves,
Indirect Push support plate 404 and sealing performance testing machine structure 3 enter in threeway supervisor from 201 other end of cylinder, work as stop nut
The positioning plate for being supported plate driving mechanism 402 stops that limiting plate 403 just stops moving, due to having mixed up sealing performance survey in advance
3 position of test-run a machine structure, sealing performance testing machine structure 3 are just moved to the positive downside of branch mouth pipe.Start end cap driving mechanism 304, end cap
Driving mechanism 304 promotes all components of connecting plate 306 and the upside of connecting plate 306 to be moved toward branch mouth pipe orifice direction, upper end cover 307
Branch mouth pipe orifice is first stretched into bottom end cover 309, end cap driving mechanism 304 continues to push, when pressure ring assembly 303 rises to and threeway
Connector 5 is responsible for inner wall fitting, stops moving up, due to there is compression spring 312 to connect between pressure ring assembly 303 and connecting plate 306, even
It is fixedly connected again between fishplate bar 306 and upper end cap assemblies 301, upper end cover 307 also stops moving up；Bottom end cover 309 continues to move up, with
Upper end cover 307 extrudes branch mouth seal of tube circle 308, and branch mouth seal of tube circle 308 is expanded, and branch mouth inside pipe wall gluing, sealing, if plus
Working drawing is true, and at this time, supervisor's inner wall sealing circle 311 of 305 upper surface of supervisor's inner wall sealing block is also just pasted with 5 inner wall of three-way connection
Close crush seal；If being machined with deviation, upper end cover 307 and bottom end cover 309 have been bonded or can not extrude again expansion branch mouth
Seal of tube circle 308, supervisor's inner wall sealing circle 311 are not bonded also with 5 inner wall of three-way connection, then end cap driving mechanism 304 may proceed to
Push, at this time, another is moved up for bottom end cover 309 and upper end cover 307, connecting plate 306 also will be shifted up compression and pressure ring assembly 303 it
Between spring 312, until supervisor's inner wall sealing circle 311 of 305 upper surface of supervisor's inner wall sealing block is bonded with 5 inner wall of three-way connection
Crush seal.When in branch mouth seal of tube circle 308 and branch mouth inside pipe wall gluing, sealing, supervisor's inner wall sealing circle 311 and three-way connection 5
Wall gluing, sealing, just forms a sealing cavity 7 between two sealing rings, and the weld 8 of three-way connection 5 is exactly in this
On a 7 wall of sealing cavity, in this way, just gas channels 6 can be tested by two be responsible on inner wall sealing block 305, it is empty toward sealing
Pressurization, pressure release in chamber 7, experiments of sealing performance is carried out to weld 8.
