Abstract
The invention relates to thermocouple lead sealing equipment, which is characterized in that one end of a hollow joint is connected in container wall, and the other port thereof is internally provided with a hemispherical sealing face mechanism composed of a thermocouple probe, a nut, a hemispherical face head and a sealing adhesive layer hole, wherein, one end of the hemispherical face head is internally provided with the sealing adhesive layer hole; the other end thereof is the hemispherical face head; the port of the hollow joint is internally provided with a sealing face sealed with the hemispherical face head of which the root part is provided with a step; after the hemispherical face head step is installed in the step-slot of the nut, the screw thread at the other end of the nut is connected on the hollow joint, so that the probe of the thermocouple probe penetrates the sealing adhesive layer of the hemispherical face head and exposes outside the end face of the hollow joint viaa hollow hole in the hollow joint; and the adhesive layer for fixing the thermocouple probe is filled in the sealing adhesive layer. The thermocouple lead sealing equipment of the invention has the advantages of reasonable design, compact structure, simplicity and practicability, good seal performance, big loading capacity, reusability, convenient assembly and disassembly and very convenient use and the like.
Description
Technical field
The invention belongs to the annex that temperature measuring device is used, particularly measure a kind of thermocouple lead sealing equipment of temperature in the high pressure vessel.
Background technology
Well-known, high pressure vessel must be drawn thermocouple lead when carrying out the inner wall temperature measurement from container inner wall, must be provided with the lead-in wire fairlead at chamber wall, be the high pressure sealing at assurance container fairlead fairlead place, and the special-purpose thermocouple lead sealing equipment of installing; Its structure bag hollow joint, nut, sealing gasket and thermocouple probe, usually the end with the joint of interior dress thermocouple probe is welded on the container, the other end of joint is fixed on thermocouple probe in the joint with nut, simultaneously the sealing gasket of installing red copper pad or glue system between the surface of contact of nut and joint; To guarantee that this lead sealing equipment seepage must not occur when the hydraulic testing.Its shortcoming and defect part is: contour structures is bigger, the sealing gasket of installing red copper pad or glue system between joint and nut surface of contact, the seal and pressure bearing ability of its sealing surface is little, generally is applied in the lower occasion of pressure, when pressure was high, the seepage phenomenon often appearred easily; This coupling is to be threaded with nut, during installation, needs the rotation nut thermocouple probe that has connecting line can be fixed on the joint, damages thermopair and connecting line during rotation easily.
Summary of the invention
The present invention is intended to the shortcoming and defect part that exists in above-mentioned technology, and provides not only reasonable in design, compact conformation, simple and practical, both good seal performance, bearing capacity is big again, and have a repeated use, easy to loading and unloading and use a kind of very easily thermocouple lead sealing equipment.
The objective of the invention is to adopt following technical scheme to realize: described thermocouple lead sealing equipment, comprise hollow joint, nut, thermocouple probe and sealing surface, it is characterized in that: the equal threading section in the two ends of its hollow joint, at an end of chamber wall internal thread connection hollow joint, installing semisphere sealing surface mechanism in the another port of hollow joint; Described semisphere sealing surface mechanism is by thermocouple probe, nut, semisphere face head and sealant layer hole are formed, be processed with the sealant layer hole in one end of described semisphere face head, its other end is a semisphere, be processed with the hole that holds thermocouple probe in the semisphere face head, shape with semisphere face head, size is provided with the sealing surface that seals mutually with semisphere face head accordingly in the port of hollow joint, be provided with step at semisphere face head heel, be processed with the step groove that holds step in one end of nut, the step for the treatment of semisphere face head is packed into behind the step groove of nut, the other end of nut is threaded on the hollow joint, the sound end of thermocouple probe is passed hollow hole stretches outside the end face of hollow joint in the sealant layer aperture hollow joint of semisphere face head; Fill the fixedly sealant layer of thermocouple probe in the sealant layer hole in semisphere face head.
Fill the sealant layer of epoxy resin in the described sealant layer hole.
Junction lateral surface between two external thread sections of described hollow joint is provided with positive six side's steps of pulling usefulness for spanner.
Principle of the present invention and operation are described below:
Before the use, the hollow hole that at first sound end of thermocouple probe is passed in the sealant layer aperture hollow joint in the semisphere face head stretches outside the end face of hollow joint; Fill the fixedly sealant layer of thermocouple probe then in the sealant layer hole in semisphere face head; Treat to use after the normal temperature cure in 24 hours.During use, earlier joint is contained on the vessel by being threaded, at this moment, the sound end of thermocouple probe is in the container by the rotation nut sealing surface in the port of semisphere face head and hollow joint is sealed mutually, thus the sealing fully of realization thermocouple probe.
Combine the above technical scheme of being taked, realize purpose of the present invention.
Compared with prior art, the present invention is not only reasonable in design, and compact conformation is simple and practical, both good seal performance, and bearing capacity is big again, and has repeated use, and is easy to loading and unloading and use advantages such as very convenient.
