Description
Technical field
The invention belongs to technical field of heat exchangers, and in particular to a kind of pipe close for temperature-sensing probe.
Background technique
Into the plate heat exchanger of temperature-sensing probe, the method for installing temperature-sensing probe is usually to visit temperature-sensitive for existing use
In some adapter tube of head merging heat exchanger, it is then injected into glass cement and seals pipe nozzle, fixed temperature-sensing probe is allowed to not skid off.But
Since nozzle inner wall is relatively smooth, once for a long time, glass cement is easy to fall off, and temperature-sensing probe will skid off.
Summary of the invention
The object of the present invention is to provide a kind of pipe closes for temperature-sensing probe, and temperature-sensing probe is made to be not easily disconnected from adapter tube.
Specifically, pipe close of the present invention is used to fill in adapter tube, realization is adopted the following technical solutions:
Including cylindricality barrel, direct through groove, bottom and the end being adapted with the inner wall section of the adapter tube, it is equipped in end
Pipe close gum-injecting port；Hollow structure is formed on barrel and bottom, for injecting glue；The direct through groove is worn for making to take over interior thread
It takes over out；The end is bonded pipe nozzle when barrel fills in adapter tube.
Furthermore, the barrel is cylinder.
Furthermore, the outside diameter of the barrel is equal to the inner diameter of adapter tube.
Furthermore, the outside diameter of the barrel is greater than the inner diameter of adapter tube, is squeezed pipe close in barrel
After can fill in adapter tube, and barrel is bonded with the holding of the inner wall of adapter tube.
Furthermore, the pipe close is made of elastic material.
Furthermore, the bottom of the pipe close gum-injecting port is closed by the bottom.
Furthermore, after the pipe close fills in adapter tube, the glue of injection is overflowed from pipe close gum-injecting port, and is extended to
The upper port of adapter tube.
Beneficial effects of the present invention are as follows: the pipe close for temperature-sensing probe of the invention, for first blocking pipe nozzle, then
It reinjects glass cement and seals pipe nozzle, so, glass cement is just not easy to skid off or even fall off, and temperature-sensing probe is more firm.

Specific embodiment
Below with reference to embodiment and referring to attached drawing, present invention is further described in detail.
Embodiment 1:
One embodiment of the present of invention is a kind of pipe close for temperature-sensing probe.
Referring to Fig.1~Fig. 3, pipe close 3 include 301, direct through groove 304 of cylindrical type barrel, bottom 302 and end 303,
End 303 is equipped with a pipe close gum-injecting port 305.Barrel 301 has certain wall thickness, forms hollow structure with bottom 302.
The outside diameter of barrel 301 is equal to the inner diameter of adapter tube 2.Pipe close 3 is filled in using there is the material of certain elasticity to be made
Enter before adapter tube 2 can appropriate container wall 301 so that barrel 301 is easy to fill in adapter tube 2.And after barrel 301 fills in adapter tube 2,
The bottom 302 of pipe close 3 is located in adapter tube 2, and the end 303 of pipe close 3 stays in outside adapter tube 2, and barrel 301 and 2 inner wall of adapter tube keep pasting
It closes, and 2 inner wall of butt tube generates certain pressure, so that pipe close 3 is not easy to skid off out of adapter tube 2.As long as making pipe close in barrel
After 301 are squeezed, adapter tube 2 can be filled in, and barrel 301 is bonded with the holding of the inner wall of adapter tube 2, the outside diameter of barrel 301
The inside diameter of adapter tube 2 can be slightly larger than.When the inner wall section of adapter tube 2 is the other shapes such as rectangular, barrel 301 is also possible to
The cylindricality of the other shapes such as corresponding square column type, the i.e. inner wall section in the outer wall section of barrel 301 and adapter tube 2 are adapted.
Temperature-sensing probe 1 is put into after adapter tube 2, blocks pipe nozzle using pipe close 3, the circuit line of temperature-sensing probe 1 can be by leading directly to
Slot 304 is pierced by, to have the function that fixed temperature-sensing probe.Specific steps are as follows:
1, temperature-sensing probe 1 is put into adapter tube 2；
2, the circuit line of temperature-sensing probe 1 is put into the direct through groove 304 of pipe close 3；
3, the barrel 301 of pipe close 3 is filled in into adapter tube 2, and the end 303 of pipe close is made to be bonded pipe nozzle；
4, to 305 implantation glass glue of pipe close gum-injecting port, so that glass cement seals pipe nozzle.
Pipe nozzle is first blocked using pipe close 3, then reinjects the mode that glass cement seals pipe nozzle, the cylinder of one side pipe close
Wall 301, which docks inside pipe wall, the pressure being directed toward outside adapter tube, so that pipe close 3 is not easy to skid off out of adapter tube；On the other hand, pipe close 3
Between 2 inner wall of adapter tube and the circuit line of temperature-sensing probe 1, so as to use less glass cement for fixing temperature-sensing probe 1, and
And contact area is small between 2 inner wall of glass cement and adapter tube, therefore glass cement is just not easy to skid off or even fall off, temperature-sensing probe 1 is more
It is firm；In another aspect, can be before being sealed with glass cement by the position of temperature-sensing probe 1, the circuit line of temperature-sensing probe, adapter tube 2
It sets and is fixed, compared with directly sealing pipe nozzle with glass cement, more convenient operation.To sum up, 3 structure of pipe close of the utility model
Simply, installation effectiveness can be improved, save installation cost, improve sealing effect.
Because need to be used cooperatively with the electric lead of temperature-sensing probe 1, pipe close 3 can be made of nonmetallic.It is readily apparent that, when
When not needing electrical isolation, pipe close 3 can also be made of metal, to utilize the elasticity and rigidity of metal.
The shape of direct through groove 304 is not limited to structure shown in Fig. 1, can also be other structures, as long as used structure energy
Realize above-mentioned function.Direct through groove on pipe close can also be with more than one.Since by the way of groove at side surface, temperature-sensitive is visited
First 1 can first be placed in adapter tube 2, install pipe close 3 again later, avoid in the prior art, it is necessary to first by temperature-sensing probe 1 from pipe close 3
Across carry out again later merging adapter tube 2 operation, simplify operating process, and make temperature-sensing probe 1 during merging not vulnerable to
To damage.
Although the present invention has been described by way of example and in terms of the preferred embodiments, embodiment is not for the purpose of limiting the invention.Not
It is detached from the spirit and scope of the present invention, any equivalent change or retouch done also belongs to the protection scope of the present invention.Cause
This protection scope of the present invention should be based on the content defined in the claims of this application.
