Description
Technical field
The utility model relates to a kind of seal arrangement, refers to a kind of sensor conductor seal arrangement especially.
Background technique
In order to the liquid medium temperature in test container, pressure and other parameters, need at liquid container sensor installation.As shown in Figure 1, sensor 22 is positioned at liquid-container, and sensor conductor 2 and terminal 21 need be connected with external instrument through the container wall 12 of liquid-container, and the gap between sensor conductor 2 and mounting hole 11 needs to seal to avoid leak of liquid.General seal arrangement is difficult to realize effective sealing to the wire of sensor.
Summary of the invention
The purpose of this utility model is the sensor conductor seal arrangement providing a kind of good seal performance.
For achieving the above object, designed by the utility model for through the sensor conductor seal arrangement sealed the sensor conductor of liquid-container wall and this wall, comprise stud and nut.The axis of described stud is provided with the through hole that can pass through for sensor conductor, being provided with between the two ends screw thread of described stud can for the clamping part of spanner clamping.The outside of described clamping part can be regular hexagon, square or be with the shapes such as circle jaggy, corresponding spanner need be coordinated to carry out fastening.The inner side of described nut is provided with shoulder hole, and this shoulder hole comprises macropore and aperture, and wherein, macropore is connected with the threaded one end of stud.Transitional surface between described macropore, aperture and be provided with the metallic shim play supporting role and the rubber sheet gasket sealed between described stud, usual both sides are respectively provided with piece of metal pad, centre is provided with some rubber sheet gaskets (be generally 1 ~ 3, can adjust according to actual sealing effect).Described metallic shim and rubber sheet gasket are respectively arranged with radial groove and the radial slot for described sensor conductor radial direction being penetrated into pad center hole.The width of radial groove is suitable with the diameter of sensor conductor, and the width of radial slot is less than the diameter of sensor conductor (should be as far as possible little).For ensureing sealability, each radial groove and radial slot should stagger and install, and avoid point-blank.
When this device is installed, first the joint of sensor conductor is passed stud and nut successively; Metallic shim and rubber sheet gasket to be loaded between stud and nut and to make sensor conductor penetrate each pad center hole from the radial groove of metallic shim and the radial slot radial direction of rubber sheet gasket; The position of adjustment radial groove, radial slot makes it be in staggered distribution.Then stud is tightened and nut becomes entirety, device entirety is threaded in the mounting hole on liquid-container wall by stud, for ensureing sealing, described clamping part seals near being provided with rubber sheet gasket between the transverse end surface and container wall of liquid-container wall.
Further, for improving sealability, the through hole of one end of stud attaching nut can be expanded near its end face and form cylindricality counterbore, be respectively arranged with metallic shim on the step surface of described cylindricality counterbore and on the transitional surface of described nut, between described metallic shim, be provided with rubber sheet gasket.
Further, can arrange boss being arranged in the one side that the metallic shim on transitional surface contacts with rubber sheet gasket, the projection area of boss is less, improves clamping pressure and sealability.Similar, the one side that also can contact with rubber sheet gasket at the metallic shim of stud side arranges boss.
The beneficial effects of the utility model are: 1) adopt the metallic shim with radial groove and the rubber sheet gasket with radial slot, easily wire radial direction can be penetrated pad center hole, because the width of radial groove, radial slot is very little, and be arranged in dislocation, therefore face of leaking is little, is easy to sealing; 2) when nut is tightened on double threaded screw, the axial pre tightening force of generation makes rubber sheet gasket be out of shape and by wire banding, ensures that good seal does not leak; 3) this apparatus structure is simple, easy for installation, good seal performance.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Sensor conductor and seal arrangement thereof the position relationship in liquid-container as shown in Figure 1, has done detailed introduction in the introduction, has repeated no more in this.
As figures 2-6, the sensor conductor seal arrangement that the utility model improves, comprises stud 3 and nut 4.The centre of stud 3 is hexagonal clamping part 32, its axis is provided with through hole 31, and through hole 31 can pass through for sensor conductor 2 and terminal 21.The through hole 31 of stud 3 one end expands and forms cylindricality counterbore 33 near end face.Nut 4 is hexagon nut, is provided with shoulder hole 41 inside it.Shoulder hole 41 is divided into two sections according to the size of internal diameter, is called macropore 42 and aperture 43.Wherein, macropore 42 is connected with the threaded one end of stud 3, the transitional surface 44 between macropore 42, aperture 43 and be provided with two panels metallic shim 5 and two panels rubber sheet gasket 6 between the step surface 34 of cylindricality counterbore 33.Transitional surface 44 place, the external diameter of metallic shim 5 is slightly less than the diameter of macropore 42, and is greater than the diameter of aperture 43; Step surface 34 place, the external diameter of metallic shim 5 is slightly less than the diameter of cylindricality counterbore 33, and is greater than the diameter of through hole 31 (not comprising cylindricality counterbore).Metallic shim 5 and rubber sheet gasket 6 are respectively arranged with radial groove 51 and radial slot 61, and the aperture of the pad center hole 7 at its center is suitable with the aperture of sensor conductor 2.The gap width of radial groove 51 is slightly larger than the diameter of sensor conductor 2, and radial slot 61 is a slit little as far as possible.Transitional surface 44 place, the one side that metallic shim 5 contacts with rubber sheet gasket 6 is also provided with boss 52, and the external diameter of boss 52 is less than the external diameter of cylindricality counterbore 33.
During installation, two metallic shims 5 are placed on respectively on transitional surface 44 and step surface 34, two rubber sheet gaskets 6 are placed on the metallic shim 5 on step surface 34; For improving sealing, each radial groove 51 and radial slot 61 should be in staggered distribution.Because the terminal 21 of sensor is comparatively large, directly pad center hole 7 cannot be passed.Therefore sensor conductor 2 need be horizontally through radial groove 51, radial slot 61 to enter each pad center hole 7.Tighten stud 3 and become entirety with nut 4, then the other end of stud 3 is threaded onto in the mounting hole 11 on liquid-container 1.For avoiding leaking, between the container wall 12 of clamping part 32 around the side and mounting hole of mounting hole, rubber washer 8 is installed.
Sealing situation analysis: when nut 4 is tightened on stud 3, an axial pre tightening force can be produced, rubber sheet gasket 6 be deformed, its lower thickness, external diameter becomes large, produces interference fit with corresponding hole wall, forms sealing surface; Meanwhile, the internal diameter of rubber sheet gasket 6 diminishes, and wire banding is produced interference fit, and form sealing surface, the radial slot of two rubber sheet gaskets also closes simultaneously, prevents liquid from overflowing along wire.Radial stress between above-mentioned sealing surface and sensor conductor 2 plays good seal action to the sensor conductor 2 being arranged in liquid-container 1 liquid.
