Abstract
The invention provides a sealing device for multi-sensor wired measurement and control, comprising an outer cavity 8, wherein two porous ceramic pipes 5 and 7 are arranged inside the outer cavity 8; asealant 6 is placed between the two porous ceramic pipes 5 and 7; the sidewall of the sealant 6 is in contact with a compaction device; the compaction device comprises a press block 4, a positioningpin 10 and a screw cap 3; the press block 4 is positioned on the bottom of the porous ceramic pipe 5 and is in contact with the sidewall of the sealant 6; the end of the press block 4 far from the sealant is in contact with the screw cap 3 fixed on the outer cavity 8; the positioning pin 10 is arranged between the bottom of the press block 4 and the inner side of the outer cavity 8; a position ofthe screw cap 3 corresponding to a sensor conductor is provided with three porous ceramic pipes 2. The sealing device prevents fluid media on two sides of a sealed container under pressure from leaking along the outer surface of the sensor conductor or a controller conductor, can be applied to a single sensor or a controller conductor, and can also be applied to a plurality of sensors or controller conductors.
Description
Technical field
The present invention relates to a kind of packoff, particularly relate to the packoff that adopts multisensor that band means of press seals internal tank is carried out wired measuring and line traffic control is arranged.
Background technology
In scientific research and industrial practical application, often use sensor band means of press seals internal tank is carried out wired measuring and line traffic control is arranged.In packoff and installation method in the past, the fluid media (medium) of band means of press seals container both sides is the problem that often runs into along sensor conductor or controller lead outside surface generation seepage.Can influence the ambient condition of airtight container both sides like this, make the both sides environment produce cross pollution, in the time of serious even major accident can take place.
Summary of the invention
The object of the present invention is to provide a kind of packoff that is used for multi-sensor wired measuring, prevent that fluid media (medium) with means of press seals container both sides is along sensor conductor or controller lead outside surface generation seepage.
A kind of packoff that is used for multi-sensor wired observing and controlling is characterized in that, comprises exocoel 8, is provided with in the exocoel 8 between 5,7, two porous ceramic pipes 5,7 of two porous ceramic pipes and is placed with fluid sealant 6, and the sidewall of fluid sealant 6 contacts a hold down gag.
Described hold down gag comprises briquetting 4, register pin 10 and nut 3, briquetting 4 is positioned at the outside of porous ceramic pipe 5, and contact with described fluid sealant 6 sidewalls, briquetting 4 is fixed in nut 3 on the exocoel 8 away from an end in contact of fluid sealant, between briquetting 4 and exocoel 8 inboards, be provided with register pin 10, be provided with the 3rd porous ceramic pipe 2 in nut 3 and sensor conductor corresponding position.
The present invention is by hold down gag crush seal glue, makes between fluid sealant and the lead outside surface very close to each otherly, effectively prevented the fluid media (medium) seepage, guaranteed the normal operation of total system.The present invention not only can be applied to the sealing of single-sensor or controller lead, and can be applied to the sealing of a plurality of sensors or controller lead, only need on airtight container, to open a mounting hole, can solve all sensors or controller lead sealing problem, reduced instability, and economical and effective.
Description of drawings
Fig. 1 is an embodiment of the invention structural representation;
Fig. 2 is the scheme of installation on airtight container embodiment illustrated in fig. 1.
Embodiment
Fig. 1 is one embodiment of the invention structural representation, comprises exocoel 8, and exocoel 8 one ends are taper thread, and an other end is a straight thread.Be provided with two porous ceramic pipes 7,5 in the exocoel 8, be filled with fluid sealant 6 between two porous ceramic pipes, the sidewall of fluid sealant 6 contacts a hold down gag.Hold down gag is made of briquetting 4, register pin 10 and nut 3, and briquetting 4 is positioned at the outside of porous ceramic pipe 5, and contacts with fluid sealant 6 sidewalls.Briquetting 4 is away from an end coupling nut 3 of fluid sealant 6, and nut 3 also is connected with exocoel 8 by the straight thread of exocoel 8.
Fig. 2 is the scheme of installation on airtight container embodiment illustrated in fig. 1, bores the seal mounting hole on band means of press seals container wall, and tapping, in order to be connected cooperation with seal body 8 taper threads.In the work, many sensors or controller lead 1 pass two porous ceramic pipes 7,5 and fluid sealant 6, stretching into airtight container 9 measures, simultaneously apply external force to nut 3, make it promote briquetting 4 from sidewall crush seal glue 6, fluid sealant 6 is squeezed and can only stretches up and down, thereby realize that with lead the zero stand-off contacts, prevent that fluid in the container is along the conductive line surfaces seepage.Rotate in order to prevent that briquetting 4 from doing to rotate, can between briquetting 4 and exocoel 8 inboards, set up register pin 10.When preventing that nut 3 from rotating, damage sensor or controller lead 1 in addition, be provided with the 3rd porous ceramic pipe 2 in nut 3 and sensor conductor 1 contact position.
Fluid sealant 6 general rubber, nylon, the polytetrafluoroethylmaterial materials of adopting can be selected ls under the high temperature resistant condition of oil resistant.
Purposes of the present invention is not limited to the wired observing and controlling of sensor, and every relating to all is applicable to the present invention to sealing along journey of lead.
