Description

Technical Field

[0001] The utility model relates to the field of petrochemical instrument installation, in particular to a tappable embedded temperature sleeve. Background Art

[0002] In the field of petrochemical instrument installation, especially in the temperature removal and installation process of large units of solid material extruder type, temperature sleeves are indispensable and widely used. In the installation of temperature sleeves, to prevent material leakage, the sleeves must be connected to the side wall of the unit according to the temperature sleeve thread, and the embedded thermometer is inserted into the sleeve and sealed with glue.

[0003] In actual use, the extruder often has material blockage during production, which requires disassembly and cleaning. When removing the parts, the corresponding thermometer needs to be removed. However, the existing thermometer installation method in the industry is that the thermometer is integrated with the casing, which needs to be removed as a whole. During the removal process, the wires and casing need to be removed, which often causes temperature damage. In addition, because the material is solid, it often causes blockage at the threaded joint. After the threaded joint is blocked, it needs to be re-tapped with a tap, which has poor operability and is time-consuming and labor-intensive to operate, affecting production. Utility Model Content

[0004] In order to solve the problems existing in the background technology, the utility model provides a tappable embedded temperature sleeve, which includes:

[0005] A main casing, in which the embedded thermometer is installed; the front end of the main casing is a sealed end, and the rear end is an open end;

[0006] A pipe sealing thread provided at the sealing end of the main casing;

[0007] A pipe tapping thread fixedly connected to the end of the pipe sealing thread;

[0008] Pipe sealing threads are provided at the open end of the main casing.

[0009] In a preferred solution, an external hexagonal nut is fixedly connected to the open end of the main sleeve.

[0010] In a preferred solution, the main casing is a stainless steel pipe.

[0011] In a preferred embodiment, the main sleeve has a length of 15-25 cm.

[0012] In a preferred embodiment, the length of the pipeline sealing thread is 1 cm.

[0013] In a preferred embodiment, the pipe tapping thread length is 1 cm.

[0014] In a preferred embodiment, the length of the sealing joint screw is 1 cm.

[0015] The beneficial effects achieved by the utility model are:

[0016] The utility model changes the tedious work of dismantling the thermometer as a whole for maintenance, debugging and replacement into only dismantling the embedded thermometer for maintenance, debugging and replacement. The embedded thermometer is installed in the main casing by designing the main casing and the pipe sealing thread, pipe tapping thread, sealing joint screw and external hexagonal nut installed on the main casing. When the thermometer needs to be removed, only the cable sealing joint needs to be loosened and the embedded thermometer can be pulled out without dismantling the temperature casing as a whole, thereby realizing the functions of facilitating maintenance, debugging and replacement and avoiding damage to the thermometer. The utility model is suitable for the installation of thermometers of extruder type units and also suitable for the installation of temperature detection instruments of other units. It is simple to operate and novel in structure. No special tools are required for installation. It is very convenient and low in cost, and suitable for promotion. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the utility model. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative, and the utility model is not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0021] Reference Figure 1 The utility model provides a tappable embedded temperature sleeve, which includes a main sleeve 1. The main sleeve 1 is preferably a stainless steel pipe with a length of 15-25 cm.

[0022] The embedded thermometer is installed in the main casing 1; the front end of the main casing 1 is a sealed end, and the rear end is an open end; a pipe sealing thread 2 is arranged at the sealed end of the main casing 1; a pipe tapping thread 3 is fixedly connected to the end of the pipe sealing thread 2; and a pipe sealing thread 2 is arranged at the open end of the main casing 1. The lengths of the pipe sealing thread 2, the pipe tapping thread 3, and the sealing joint screw 4 are preferably 1 cm.

[0023] The open end of the main sleeve 1 is fixedly connected with an external hexagonal nut 5. When disassembling and installing the main sleeve 1, it can be achieved by twisting the external hexagonal nut 5. The pipe sealing thread 2 is connected to the unit through the external thread to play a fixing and sealing role; the pipe tapping thread 3 is connected to the unit thread to clean the thread screw plugging material, which is convenient for disassembly and assembly of the pipe sealing thread 2. The sealing joint screw 4 is connected to the cable sealing joint to fix the embedded thermal resistor to prevent the embedded thermal resistor from falling off due to vibration.

[0024] When in use, just loosen the connection between the cable sealing joint and the sealing joint screw 4 and pull the embedded thermometer out of the main sleeve 1 without removing the temperature sleeve as a whole, thereby facilitating maintenance, debugging and replacement while avoiding damage to the function of the thermometer.
