Abstract
The invention provides a method and a special device for sealing an educed lead of a sensor of a pressure-bearing container. A threaded through hole is formed in a wall of the pressure-bearing container, and a special sealing device is matched with the threaded through hole, so that the detachability of the sealing device is realized, the technical problems of impossibility of increasing, decreasing and detaching the lead or big measuring error in the traditional method are solved, and the method is suitable for the measurement for the strain capacity of the inner wall of the pressure-bearing container.
Description
Technical field
The present invention relates to a kind of lead encapsulating method and device of drawing.In particular, be that a kind of pressure resistant vessel sensor is drawn lead encapsulating method and isolated plant.
Background technique
Pressure resistant vessel inwall strain measurement required precision is high, measure electrical signal a little less than, systematic measurement error control difficulty is big.Pressure resistant vessel internal electrical signal is drawn two kinds of methods of general employing.Method 1 is on container wall, to drive wire guide, use have certain intensity the pipe sealing with the direct embedding of lead to pressure resistant vessel.Method 2 is to use seal socket, and to socket, the lead of internal tank and contact pin weld contact pin by embedding, and the plug of external container and contact pin are pegged graft, and seal socket and container wall adopt the seal ring sealing.Before a kind of advantage of method be that electrical signal is directly drawn through lead, the measuring system error is little, shortcoming is that embedding is a kind of permanent connection, and is on-dismountable, is applicable to accurate on-line measurement.The advantage of method 2 is that plug is detachable, and shortcoming is to need through welding or grafting, and the measuring system error is big, is suitable for the not high measurement of required precision.
Summary of the invention
The purpose of this invention is to provide a kind of pressure resistant vessel sensor and draw the method and the isolated plant of lead sealing, address the above problem.
Technological scheme of the present invention is following:
The pressure resistant vessel sensor is drawn lead sealing isolated plant, comprises pedestal, seal ring, rubber ring, enclosing cover, metal gasket, and pedestal is the ladder tubulose; Outside thread with pressure resistant vessel wall upper screwed hole coupling is arranged at the bottom, and the outside thread that cooperates with enclosing cover is arranged at top, and enclosing cover is the cap shape; Internal thread is arranged on the inwall; There is the hole of drawing lead at the enclosing cover center, and rubber ring and metal gasket are installed in the inner chamber of pedestal top successively, and size and pedestal inner cavity size are complementary.Have tapped through hole on the pressure resistant vessel wall, the pedestal lower external thread matches with pressure resistant vessel wall upper screwed hole, and seal ring is enclosed within on the pedestal lower thread, and during threaded together, the pedestal step compresses the sealing that seal ring is realized pedestal and container wall.When tightening enclosing cover, enclosing cover is realized the sealing between pedestal and the lead through metal gasket extruding rubber ring.
Further, the material of seal ring is a rubber;
Further, the quantity of metal gasket is one or more;
Further, there is annular knurl the enclosing cover outside.
The pressure resistant vessel sensor is drawn the lead encapsulating method:
The first step is opened a tapped through hole on the pressure resistant vessel wall;
Second step, the every lead of drawing is all smeared sealer, make lead form an integral body, can not produce leakage between lead and the lead;
The 3rd step, opsition dependent, annexation preassembly seal arrangement, and whole lead passed seal arrangement, and smear sealer at lead and rubber ring contact position;
In the 4th step, the pedestal bottom of seal arrangement is tightened in the tapped through hole on the pressure resistant vessel wall, and tightens the seal arrangement enclosing cover simultaneously;
The 5th step, leave standstill 1-3 after individual hour, begin to inflate pressure measurement.
The present invention compares with aforesaid method 2 through dismountable private seal apparatus, and this method is not destroyed the integrity of sensor conductor, has guaranteed that systematic measurement error is minimum.Compare with aforesaid method 1, this method is passed the lead changeable and the dismounting of seal arrangement, when increasing or reduce number of conductors, controls the crush of rubber ring through the quantity of adjustment metal gasket, still can realize effective sealing of container.
