Description

Technical Field

[0001] This utility model relates to the field of thermometer protective sleeves, specifically to a thermometer sleeve assembly for spherical tanks. Background Technology

[0002] Currently, in the design of spherical tanks, thermometers need to be installed to monitor the internal temperature. The thermometer probes cannot directly contact the medium inside the spherical tank. The thermometer sleeves need to be pre-flowed during the manufacturing of the spherical tank to facilitate the subsequent installation of the thermometers. Most of the existing thermometer sleeves are non-removable structures that are directly welded to the tank wall. When the thermometer model changes, it can only be cut and re-welded with a suitable thermometer sleeve, which affects the overall strength of the spherical tank. Utility Model Content

[0003] The purpose of this utility model is to address the above-mentioned shortcomings by providing a thermometer sleeve assembly for spherical tanks.

[0004] This utility model includes an outer sleeve and an inner sleeve. The top of the outer sleeve has a sleeve through hole, and the bottom of the outer sleeve is provided with a connecting flange. A set of annular sealing parts are arranged in sequence inside the outer sleeve. The tail of the inner sleeve is provided with a thermometer connection part, and an integral flange is provided above the thermometer connection part. The inner sleeve is inserted into the outer sleeve, and the top of the inner sleeve extends upward through the sleeve through hole. The integral flange is sealed and connected with the connecting flange. The top of the integral flange is a clamping ring, which clamps and fixes the set of annular sealing parts. The inner wall of the annular sealing parts is tightly fitted with the outer wall of the inner sleeve.

[0005] The thermometer connection part is an internally threaded sleeve, and the inner cavity of the internally threaded sleeve is connected to the inner sleeve tube.

[0006] The thermometer connection is a flange interface. The upper part of the flange interface is an inverted frustum shape, and the bottom of the flange interface is equipped with a thermometer connection flange. The inner cavity of the flange interface is connected to the inner sleeve.

[0007] An annular sealing groove is provided on the bottom end face of the connecting flange, and a sealing ring is provided in the annular sealing groove. An annular protrusion is provided on the top end face of the integral flange, and the annular protrusion is pressed against the sealing ring.

[0008] The bottom opening of the inner sleeve is provided with an annular inner bevel.

[0009] The bottom opening of the flange interface is provided with an annular external bevel.

[0010] The annular sealing part is a graphite sealing ring.

[0011] The top of the inner sleeve is provided with a hemispherical end cap.

[0012] The hemispherical head has a conical receiving cavity inside.

[0013] The advantages of this utility model are: the thermometer sleeve is detachable and easy to replace, and it can be adapted to different models of thermometers. Attached Figure Description

The top of the outer sleeve 1 has a sleeve through hole, and the bottom of the outer sleeve 1 is provided with a connecting flange 3. A set of annular sealing parts 4 are arranged in sequence inside the outer sleeve 1. The tail of the inner sleeve 2 is provided with a thermometer connection part, and an integral flange 5 is provided above the thermometer connection part. The inner sleeve 2 is inserted into the outer sleeve 1, and the top of the inner sleeve 2 extends upward through the sleeve through hole.
