The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

FIG. 1 is a sectional view of a reaction vessel thermometer sleeve for a water reducer production plant provided in an embodiment of the present application along its axis. The embodiment of the application provides a reation kettle thermometer sleeve pipe for water-reducing agent workshop, as shown in fig. 1, including sleeve pipe main part 100, ring flange 200 and polytetrafluoroethylene layer 300, wherein sleeve pipe main part 100 is used for holding the thermometer, and ring flange 200 is used for installing with reation kettle, and polytetrafluoroethylene layer 300 is used for protecting sleeve pipe main part 100 and ring flange 200.

One end of the socket main body 100 is opened and the other end is closed so that the thermometer can be put into the socket main body 100 from the opened end and abut against the closed end.

The annular flange 200 is coaxially disposed at the open end of the sleeve body 100, and generally, as shown in fig. 1, the inner diameter of the annular flange 200 is equal to the inner diameter of the opening of the sleeve body 100.

As shown in fig. 1, the ptfe layer 300 is coated on the outer wall of the casing main body 100 and the annular flange 200, and the edge of the ptfe layer 300 is aligned with the inner edge of the annular flange 200 (i.e., aligned at a), which can be understood as: the teflon layer 300 wraps from the closed end of the sleeve body 100, extends along the outer wall of the sleeve body 100 to the annular flange 200, and wraps the annular flange 200 to finally align with the inner edge of the annular flange 200.

Compared to the prior art, the thermo-well tube is provided with the teflon layer 300, and the rim of the teflon layer 300 is aligned with the inner rim of the annular flange 200, so that the outer surface of the tube body 100 and the outer surface of the annular flange 200 are entirely covered with the teflon layer 300. When using, even this thermo-well tube takes place the swing, because polytetrafluoroethylene layer 300 has certain ductility, can not take place the problem of fracture in the junction of cover pipe main part 100 and ring flange 200 yet, make cover pipe main part 100 and ring flange 200 still can be better protection, avoid the corruption of corrosive materials to the life of extension thermo-well tube.

In order to increase the acting force between the ptfe layer 300 and the annular flange 200, in some embodiments, as shown in fig. 1 and fig. 2, a plurality of first grooves 400 are formed in the annular flange 200, a portion of the ptfe layer 300 is filled in the plurality of first grooves 400, and the first grooves 400 are formed, so that the contact area between the ptfe layer 300 and the annular flange 200 is increased, the acting force between the ptfe layer 300 and the annular flange 200 is increased, and meanwhile, the first grooves 400 can also play a role in blocking the ptfe layer 300, thereby preventing the ptfe layer 300 from sliding off the annular flange 200.

In order to make the force applied between the ptfe layer 300 and the annular flange 200 uniform in all directions, in some embodiments, as shown in fig. 2, the plurality of first grooves 400 includes a plurality of first groove sets 410, and the plurality of first groove sets 410 are uniformly arranged along the circumferential direction (i.e., the a direction) of the annular flange 200, so that the force applied in all directions is uniform and is prevented from being larger and smaller when the ptfe layer 300 is in contact with the annular flange 200.

In order to reduce the manufacturing difficulty, in some embodiments, as shown in fig. 2, the plurality of first grooves 400 in each first groove group 410 are arranged at intervals along the radial direction (i.e., the b direction) of the annular flange 200, and the arrangement of the first grooves 400 in the first groove group 410 is simple, the design is simple, and the manufacturing is convenient.

In some embodiments, the depth of the first groove 400 is 2mm to 4 mm. Compared with the case that the depth is less than 2mm, the depth in the range is larger, so that the contact area of the polytetrafluoroethylene layer 300 and the first groove 400 is larger, and the acting force between the polytetrafluoroethylene layer 300 and the annular flange 200 is increased. This range of depths is smaller than if the depth is greater than 4mm, avoiding excessive degradation of the structural strength of the annular flange 200, making it structurally strong enough for installation.

Similarly, in order to increase the acting force between the ptfe layer 300 and the sleeve main body 100, in some embodiments, as shown in fig. 1 and fig. 2, a plurality of second grooves 500 are disposed on the outer wall of the sleeve main body 100, a part of the ptfe layer 300 is filled in the plurality of second grooves 500, and the second grooves 500 are disposed, so that the contact area between the ptfe layer 300 and the sleeve main body 100 is increased, the acting force between the ptfe layer 300 and the sleeve main body 100 is increased, and meanwhile, the second grooves 500 can also block the ptfe layer 300, thereby preventing the ptfe layer 300 from sliding off the sleeve main body 100.

In order to make the force between the ptfe layer 300 and the sleeve body 100 uniform in all directions, in some embodiments, as shown in fig. 2, the second grooves 500 include a plurality of second groove sets 510, and the second groove sets 510 are uniformly arranged along the circumferential direction (i.e., a direction) of the sleeve body 100, so that the force in all directions is uniform and is prevented from being larger and smaller when the ptfe layer 300 is in contact with the sleeve body 100.

In order to reduce the manufacturing difficulty, in some embodiments, as shown in fig. 2, the plurality of second grooves 500 in each second groove group 510 are arranged at intervals along the axial direction (i.e., c direction) of the sleeve main body 100, and the second grooves 500 in the second groove group 510 are arranged in a simple manner, and are simple in design and easy to manufacture.

In some embodiments, the depth of the second groove 500 is 2mm to 4 mm. This range of depth is greater than the case where the depth is less than 2mm, so that the contact area of the teflon layer 300 with the second groove 500 is greater, increasing the force acting between the teflon layer 300 and the sleeve body 100. This range of depths is smaller than the case where the depth is greater than 4mm, avoiding excessively lowering the structural strength of the socket body 100, allowing it to have sufficient structural strength for receiving and supporting the thermometer, and withstanding impact from the contents of the reaction vessel.

In some embodiments, the polytetrafluoroethylene layer 300 has a thickness of 6mm to 10 mm. This range of thickness is thicker than if the thickness is less than 6mm, and the polytetrafluoroethylene layer 300 provides better protection to the sleeve body 100 and the annular flange 200. Compared with the thickness of more than 10mm, the thickness in the range is thinner, the material of the polytetrafluoroethylene layer 300 is less, and the material cost is reduced.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present application, and not for limiting the same; although the present application has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art; the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present application.
