Nonmetallic protection pipe bearing structure, including hold-down bolt, press packing ring, seal washer, connector, nonmetallic protection
Pipe；The nonmetallic protection pipe one end open, other end closing, the connector is stretched into the openend of the nonmetallic protection pipe
It is interior, it is described to press packing ring and seal washer is arranged in the connector and is placed in the nonmetallic protection pipe, the compression
Bolt is screwed in the connector makes seal washer deformation reach sealing by pressing packing ring, is set inside the hold-down bolt
There is cavity, the cavity is connected with the nonmetallic protection pipe.
In said structure, the nonmetallic protection pipe for playing pressure-bearing protective effect passes through the connector to play a supportive role, gasket
Enclose and press packing ring and be sequentially placed into connector so that seal washer and press packing ring and be sleeved in nonmetallic protection pipe, revolve at this time
Enter hold-down bolt, press packing ring so that seal washer deformation reaches sealing.
Preferably, the packing ring that presses is stainless steel washer.
Preferably, the seal washer is graphite gasket.
A kind of warm calorimetric coupled device with nonmetallic protection pipe bearing structure, including nonmetallic protection as described above
Pipe bearing structure, terminal box, the connecting tube being connected with terminal box, thermocouple inner core, the connecting tube and the hold-down bolt phase
Even, the thermocouple inner core is stretched out out of described terminal box and extend into the nonmetallic protection pipe.
Further, the connector connecting flange flange.
Beneficial effect is：Nonmetallic protection structure is compressed using mechanical system, is avoided welding, is simplified assembling work
Skill, while preferable using the sealing effect that reaches after the compression of soft state graphite, overcome bonding agent can not pressure-bearing the shortcomings that；With non-
The warm calorimetric coupled device air-tightness of metal coating structure is good, can be used in the range of certain pressure.

Embodiment
The utility model is further described with reference to embodiment.
Embodiment 1：
As shown in Figure 1, nonmetallic protection pipe bearing structure, including hold-down bolt 1, press packing ring 2, seal washer 3, connection
First 4, nonmetallic 5 one end open of protection pipe described in nonmetallic protection pipe 5, other end closing, the opening of the nonmetallic protection pipe 5
End is stretched into the connector 4, described to press packing ring 2 and seal washer 3 is arranged in the connector 4 and is placed on the non-gold
Belong in protection pipe 5, the hold-down bolt 1 is screwed in the connector 4 reaches the deformation of seal washer 3 by pressing packing ring 2
To sealing, the hold-down bolt 1 is internally provided with cavity 6, and the cavity 6 is connected with the nonmetallic protection pipe 5.
Preferably, described press the stainless steel washer of 2 selected as of packing ring.
Preferably, the 3 selected as graphite gasket of seal washer.
Nonmetallic protection pipe bearing structure among the present embodiment, the nonmetallic protection pipe 5 for playing pressure-bearing protective effect pass through
The connector 4 to play a supportive role, stainless steel washer and graphite gasket are sequentially placed into connector so that stainless steel washer and graphite
Packing ring is sleeved in nonmetallic protection pipe 5, screws in hold-down bolt 1 at this time, compresses stainless steel washer so that graphite gasket deformation reaches
Sealing.Compressed using mechanical system, avoid welding, simplify packaging technology, while reach after being compressed using soft state graphite
