Description

Technical Field

[0001] The utility model relates to the technical field of temperature transmitters, and more specifically, to a temperature transmitter connection component. Background Art

[0002] The temperature transmitter uses thermocouples and thermal resistors as temperature measuring elements. The output signal from the temperature measuring element is sent to the transmitter module. After being processed by circuits such as voltage stabilization and filtering, operational amplification, nonlinear correction, V / I conversion, constant current and reverse protection, it is converted into a 4-20mA current signal 0-5V / 0-10V voltage signal that is linearly related to the temperature, and an RS485 digital signal output.

[0003] The display of the existing temperature transmitter is generally fixed on one side. Since most of the existing equipment needs to be installed close to the tank or pipe, the display on the temperature transmitter cannot be adjusted after the temperature transmitter is installed, resulting in unclear observation of the display facing the tank by the staff, which in turn affects the understanding and statistics of the data.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

The temperature transmitter can be rotated and installed at a desired location through the connection assembly, so that the temperature transmitter can adapt to different installation environments. After the installation is completed, the display table can be observed and understood by rotating the temperature transmitter.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a temperature transmitter connection assembly, including a temperature transmitter, and a thermocouple arranged on the temperature transmitter through a protective tube, the protective tube is provided with a limit plate, and the two ends of the limit plate are respectively provided with a fixed sleeve and a limit disk, the fixed sleeve and the limit disk are threadedly connected, the limit plate is rotatably established between the fixed sleeve and the limit disk, the fixed sleeve is threadedly connected with a sealing connection sleeve, the sealing connection sleeve is provided with a mounting portion at one end away from the fixed sleeve, and a sealing member is provided inside the sealing connection sleeve.

[0007] Preferably, a static sealing ring is sleeved on the thermocouple, an annular groove is formed on a side of the static sealing ring close to the fixed sleeve, the sealing member is arranged in the annular groove, and the sealing member is fitted with the fixed sleeve.

[0008] Preferably, a groove is provided on the inner wall of the sealing connection sleeve on one side close to the fixed sleeve, an elastic member is provided in the groove, and a dynamic sealing ring that fits with the static sealing ring is provided at the end of the elastic member.

[0011] The utility model has the following beneficial effects:

[0012] By arranging a static sealing ring which is sleeved on the protective tube and sealed therewith, and the threaded sealing connection sleeve and the fixed sleeve are acted upon by the elastic member and the dynamic sealing ring, the static sealing sleeve always squeezes the sealing member, and the sealing member seals the sealing connection sleeve and the fixed sleeve. After the temperature transmitter is rotated for a long time, there is a slight friction between the static sealing ring and the dynamic sealing ring. The force of the elastic member can exert a mutual squeezing force on the static sealing ring and the dynamic sealing ring, thereby achieving a continuous sealing effect, so that the temperature transmitter can be rotated to adjust the angle to adapt to different installation environments, and at the same time can achieve a good sealing effect.

[0020] The fixing sleeve 5 and the limiting disk 4 are threadedly connected, and then the sealing member 8 is sleeved on the protective tube 2 to thread the sealing connection sleeve 6 and the fixing sleeve 5, so that the sealing member 8 seals between the fixing sleeve 5 and the sealing connection sleeve 6 to prevent leakage of the fixing sleeve 5 and the sealing connection sleeve 6. The temperature transmitter 1 is installed at the required position through the sealing connection sleeve 6, the fixing sleeve 5 and the limiting disk 4. The staff rotates the temperature transmitter 1 so that the display table of the temperature transmitter 1 can be rotated to a suitable position for the staff to count and understand.

[0021] refer to Figure 3 and Figure 4 As shown: a static sealing ring 9 is sleeved on the thermocouple, and the static sealing ring 9 is used to seal the protection tube 2.
