Abstract
The utility model discloses an axially adjustable eddy current sensor sealing connector, which comprises a sealing flange. The sealing flange comprises a disc and a cylinder. The inner wall of the cylinder is provided with a stepped hole in the middle of which an inner boss is formed. The two ends of the inner wall of the cylinder are provided with a thread. An eddy current sensor is arranged in the cylinder. A sleeve and a locking sleeve are arranged between the cylinder and the eddy current sensor. A sealing washer is arranged between the sleeve and the inner boss. The outer circumference of the cylinder of the sealing flange is provided with an O-shaped sealing ring. As the sealing flange and a shell of the sensor are connected with the thread, the shell of the sensor is rotated to axially adjust the sensor. Therefore, the distance between the sensor and the tested object is adjusted on the spot, not influencing the sealing performance and improving the working efficiency.
Description
Technical field
The utility model belongs to a kind of sealing and connecting device of eddy current sensor, is specifically related to a kind ofly can be used for vacuum or the adjustable eddy current sensor sealing and connecting device of axial location in the environment of gas differential pressure is arranged.
Background technology
Eddy current sensor is a kind of non-contact sensor of widely used measuring vibrations, generally speaking, on the shell of eddy current sensor screw thread is arranged, by being threaded, be installed in the screw of machine casing, fix with nut then, the distance of eddy current sensor and testee also can be by the adjusting that is threaded.But at some in particular cases, being operated in vacuum person as testee has in the environment of gas differential pressure, and this screw connection structure can't guarantee vacuum seal, just can not use.Its solution is that the shell with sensor is made into flange, designs sealing surface on machine casing, and the two and O RunddichtringO are formed hermetically-sealed construction, realize sealing.The shortcoming of this structure is that the distance of eddy current sensor and testee is fixed.Be positioned at outside the working range of sensor if find the distance of eddy current sensor and testee when installing, just must revise the size of hermetically-sealed construction,, waste time and energy as thickness or the redesign processing eddy current sensor of revising the sensor flange.
Summary of the invention
The utility model provides in order to overcome the shortcoming that exists in the prior art, the eddy current sensor sealing and connecting device that provides a kind of axial location adjustable is provided, be implemented in guarantee sealing, and can the Field adjustment eddy current sensor and the distance of testee.
The technical solution of the utility model is: the eddy current sensor sealing and connecting device that a kind of axial location is adjustable, comprise seal flange, and seal flange is made up of disk and cylindrical shell.Inwall at described cylindrical shell forms shoulder hole, forms inner convex platform in the middle of shoulder hole, forms screw thread at the both ends of cylinder inboard wall, is provided with eddy current sensor in cylindrical shell.
Between cylindrical shell and eddy current sensor, be provided with sleeve and lock sleeve, between sleeve and inner convex platform, be provided with packing washer.
The cylindrical of the cylindrical shell of seal flange is provided with the O RunddichtringO.
Upper end at sleeve is provided with lock sleeve.
The utility model is owing to adopted seal flange to be threaded with the eddy current sensor housing, by the rotating vortex sensor housing, can regulate the axial location of sensor, thereby realize the distance of Field adjustment sensor and testee, and do not influence sealing, also improved work efficiency simultaneously.

Embodiment
Below, in conjunction with the accompanying drawings and embodiments the utility model is elaborated:
As shown in Figure 1, 2, the eddy current sensor sealing and connecting device that a kind of axial location is adjustable, comprise seal flange 1, seal flange 1 is made up of disk 7 and cylindrical shell 8, be circumferentially formed a plurality of connecting holes 9 at disk 7 near cylindrical, present embodiment is four, at the inwall formation shoulder hole 10 of cylindrical shell 8, in the middle of shoulder hole 10, form inner convex platform 11, form screw thread 12 at the both ends of cylindrical shell 8 inwalls.In cylindrical shell 8, be provided with eddy current sensor 5, between cylindrical shell 8 and eddy current sensor 5, be provided with sleeve 2 and lock sleeve 3, between sleeve 2 and inner convex platform 11, be provided with packing washer 4.
Eddy current sensor 5 is known commercially available, and model is TM0110, and probe 6 is installed in an end of eddy current sensor 5, and the other end is threaded.
Installation process during the utility model work is:
As shown in Figure 3, during installation, at first to be the end penetrate in the cylindrical shell 8 from the lower end of seal flange 1 to pop one's head in 6 with eddy current sensor 5.Then, head one end at sensor, pack into successively packing washer 4, sleeve 2 and lock sleeve 3, utilize being threaded an of end of the screw thread of eddy current sensor 5 one ends and seal flange 1, adjust the correct position between probe 6 and the testee, then, with lock sleeve 3 lock sealing packing rings 4, thereby realize sealing.At last O RunddichtringO 13 is packed on the cylindrical shell 8 of seal flange 1, pass connecting hole 9 with bolt seal flange 1 is fixed on the tested machine case 14, and compress O RunddichtringO 13.
The utility model since seal flange and sensor housing by being threaded, by the rotation sensor housing, promptly can regulate the axial location of sensor, thereby realize the distance of Field adjustment sensor and testee, and do not influence sealing, also improved work efficiency simultaneously.
