Technical Field

[0001] The utility model belongs to the technical field of double-flange differential pressure transmitters, and in particular relates to a double-flange differential pressure transmitter. Background Art

[0002] The double flange differential pressure transmitter is a device used to measure the flow, liquid level and differential pressure of liquid, gas and steam, and then convert the measurement results into signals for output. The differential pressure transmitter is connected to the measured device with a capillary tube.

[0003] At present, after completing the measurement, the double-flange differential pressure transmitter usually requires the operator to store the capillary tube. Due to the long length of the capillary tube, the operator needs to spend a lot of time to store it. The existing equipment is difficult to automatically and quickly store the capillary tube, which reduces the storage efficiency of the capillary tube and is not conducive to the operator's use. In addition, when the equipment is stored, the flange is usually exposed to the outside world, which easily causes it to wear against other objects during the placement process, making it inconvenient to protect the flange, which is not conducive to the normal use of the equipment and reduces the practicality of the equipment.

[0006] Preferably, the protective assembly includes connecting blocks, two of which are symmetrically connected to the outer wall of the storage box, one side of one of the connecting blocks is connected to a hinge, and one of the connecting blocks is rotatably connected to a protective shell that matches the diaphragm flange through the hinge.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) The utility model sets a storage component and pulls the diaphragm flange outward, so that the diaphragm flange drives the capillary to extend to the outside of the storage box. During this process, the rod moves toward the inside of the storage box, so that the fixed plate compresses the spring. After the measurement is completed, the diaphragm flange is released. Under the elastic force of the spring, the distance between the two connecting plates gradually increases, thereby driving the capillary to move toward the inside of the storage box through the connecting ring, thereby realizing automatic and rapid storage of the capillary tube, improving the storage efficiency of the capillary tube, and facilitating the use of the operator.

[0013] (2) The utility model sets a protective component. When the diaphragm flange needs to be protected, one side of the diaphragm flange is fitted with one side of the storage box. Then the protective shell is pulled so that the protective shell rotates on the connecting block through the hinge, so that the protective shell covers the diaphragm flange inside, thereby protecting the flange and avoiding wear and tear between the flange and other objects during placement, which is beneficial to the normal use of the equipment and improves the practicality of the equipment.
