Description
Technical field
The present invention relates to mechanical pressure vessel technical field of sealing technology, and in particular to a kind of high pressure-volume that a hole is multi-thread
Device thread guide devices and its application method.
Background technology
With the physics in the relevant scientific research of high pressure or production activity, often needing the material object under progress hyperbaric environment or change
Learn the in situ measurement of parameter.Sensor is placed directly within hyperbaric environment, needs, by measuring lead, measuring signal to be transferred to high pressure
In measuring instrument outside container.Measuring signal is directed to out of high-pressure bottle outside high-pressure bottle, a special lead is needed
Device is realized.How to realize it is safe and simple effectively draw more measurement lines, be the technical issues of being related to thread guide devices structure.
Existing market is primarily present two different technical solutions：
1) one line of generally use, one hole scheme, using bullet or cylinder metal body, outsourcing insulating materials (epoxy glue+
Sand mixture or bakelite etc.), its main feature is that metallic object is exactly conducting wire, a hole only connects a lead.It needs to open on container more
A hole could realize multilead.Commercial materials experimental machine generally uses such pattern.It is that may be present using one hole scheme of a line
Problem is：When needing to draw more lead, the hole that respective numbers are got on container is needed.For common high-pressure bottle
For, it is limited that can provide the position of arrangement fairlead, draws the problem of more lead demand may result in space requirement.
Meanwhile if getting more hole on container, if position is unreasonable, problem is reduced with regard to will produce vessel strength.
2) another is the multi-thread scheme in a hole, and specific material has following several：
Patent of invention " leading technique of multiple wires from hole of vessel at high pressure " (application number 86103609) discloses one kind
The multi-thread extraction scheme in one hole, oil-proof under 1000MPa high pressures, wherein multiple conducting wires are arranged in the reserved guide groove of circular conical surface, and
It is sealed using the interior external conical sleeve of sealed insulation, which is made of organic glass, and when assembly uses heating measure.The program is suitable
For the thinner conducting wire of diameter, and the reserved guide groove number of circular conical surface accurately matches the wire count of extraction, can not increase temporarily
Or it reduces.In addition, needing heat treatment when interior external conical sleeve-dress of core sealing element-organic glass material of the device, lead
Cause the lead tapping device thermal adaptability not strong, practical sealing effect discreteness is big.
Utility model patent " high tension resistance case and lead sealing equipment " (application number 200820089786) discloses one
The conducting wire of pressure sensor is passed through metal shell, wherein stem and gold by lead sealing equipment under kind high pressure by stem
The bellmouth for belonging to shell is sintered to fix using glass powder.The lead sealing equipment is simple in structure, and greatest problem is to use glass
The connection type of powder sintering is not easy to disassemble thread guide devices from high-pressure bottle, and frequently replacing influences at high-pressure bottle perforation
Metal shell, even result in the failure of entire high-pressure bottle.
It is close that utility model patent " a kind of lead sealing equipment " (application number 201220238652.5) discloses a kind of lead
Seal apparatus, lead body pass through the stepped hole on metal shell, and the cylindrical cavity inside lead body is with multiple conducting wires by pouring
Vacuum sealing resin realizes sealing.But problem is that lead body is fixed with outside metal shell by two bolts, which sets
Meter bearing capacity is limited, and there are still the security risks of bolt element high speed pop-up.
Patent of invention " a kind of multi-thread ejector of high-pressure bottle " (application number 201410244699.6) discloses a kind of high
The multi-thread ejector of pressure vessel, the first conducting wire, the second conducting wire and privates are inserted into the hole among T-type lead bolt, and are layered
Flexible sealing resin and rigid fluid sealant are poured to fill the gap between the first conducting wire, the second conducting wire and privates and hole,
T-type lead bolt is inserted into the metal shell of high-pressure bottle, is connected using nut in the bottom of T-type lead bolt, drawn in T-type
The first O-ring of setting and the second O-ring among the metal shell of line bolt and high-pressure bottle, by the sealing in gap therebetween.T-type
Conducting wire is inserted into hole among lead bolt, is sealed using flexible sealing resin and rigid fluid sealant.It realizes one under condition of high voltage
3 line of hole draws situations such as frequent dismounting and change, specificity modules, and feature is that pin count is relatively limited, but can not meet a large amount of leads
Demand.
