Embodiment
Below in conjunction with accompanying drawing, the utility model preferred embodiment is described in detail:
Sealing surface displacement as shown in Figures 1 to 7 can detect seal assembly 100, and it is arranged between the first flange 200 and the second method 300, mainly comprises ring body 1, main seal ring 2, leaks and collect sealing ring 3 and pressure transducer 4.
Wherein, ring body 1 comprises inner ring 11 and outer shroud 12.Main seal ring 2 is located between inner ring 11 and outer shroud 12, and what it adopted is grommet type seals, and namely its upper and lower end face forms the hermetically-sealed construction of two ends for contacting with seal parts to be sealed.Leaking collection sealing ring 3 is located on the upper and lower end face of outer shroud 12, namely leaks and collects radial outside or the inner side that sealing ring 3 is positioned at hermetically-sealed construction.Draw small opening 5 and mozzle 6 is all opened on outer shroud 12; Drawing small opening 5 collects on the ring body 1 between sealing ring 3 at main seal ring 2 and leakage, it communicates (in the present embodiment with the axial both ends of the surface of ring body 1, what outer shroud 12 both ends of the surface axially also offer respectively ring-type draws bakie 9, this draws bakie 9 and collects between sealing ring 3 and the hermetically-sealed construction of main seal ring 2 in leakage, and both sides draw bakie 9 all with draw small opening 5 and be connected; If hermetically-sealed construction place leaks like this, the leak materials leaked out just can through draw bakie 9 be pooled to draw in small opening 5); Mozzle 6 with draw small opening 5 and be connected, it radially extends on outer shroud 12.The leaking medium leaked out like this can flow into mozzle 6 through drawing small opening 5, thus monitors leakage situation, can show the change of data on pressure transducer 4.Pressure transducer 4 is arranged at ring body 1 interior (as shown in Figure 1, Figure 2 with shown in Fig. 5) or is arranged at ring body 1 outside (as shown in Fig. 3, Fig. 4, Fig. 6 and Fig. 7); When pressure transducer 4 is arranged in ring body 1, it is positioned at the outer end of mozzle 6, and is connected in it, for measuring the pressure medium flowed in mozzle 6; When pressure transducer 4 be arranged at ring body 1 outer time, mozzle 6 is connected with the connecting pipe 7 be positioned at outside ring body 1, connecting pipe 7 is provided with valve 10, and pressure transducer 4 is connected with connecting pipe 7, and between ring body 1 and valve 10.
In the present embodiment, the outer end of connecting pipe 7 is connected with leakage detecting sensor 8; Leak detecting sensor 8 namely to can be used for detecting the amount of leakage, can also cost wherein be analyzed.Pressure transducer 4 can be connected with control analysis mechanism (their connected mode all can adopt remote detection or Site Detection) with leakage detecting sensor 8 simultaneously, the signal of their conveyings can be accepted like this and it is processed.
Above-mentioned leaking medium pressure can detect the using method of seal assembly, and it comprises the following steps:
A seal assembly 100 is arranged between the first flange 200 and the second flange 300 by (), the axial line of seal assembly 100, first flange 200 and the second flange 300 is all overlapped;
B () adjusts the position of the first flange 200 and the second flange 300, make multiple second bolts hole 301 of multiple first bolt hole 201 of the first flange 200 and the second flange 300 corresponding, and the first flange 200 and the second flange 300 are fixed together by inserting bolt wherein;
C detecting instrument (measurement port) is electrically connected with pressure transducer 4 by (), measure the pressure of mozzle 6 or connecting pipe 7 medium; Pressure transducer 4 is connected with control analysis mechanism with leakage detecting sensor 8 simultaneously, analyze the signal of pressure transducer 4 and the transmission of leakage detecting sensor 8, obtain the corresponding relation between pressure in dielectric leakage amount and mozzle 6 or connecting pipe 7, thus the arrival a certain time needed for leaking medium pressure determined can be calculated, and then the validity that is sealed with of pad is judged.
Above-described embodiment is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and implement according to this; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
