Technical Field

[0001] The utility model belongs to the technical field of pressure transmitters, and more specifically, particularly relates to a pressure transmitter with good fixing effect. Background Art

[0002] A pressure transmitter is a device that converts pressure into pneumatic or electric signals for control and remote transmission. It can convert physical pressure parameters such as gas and liquid sensed by the pressure measuring element sensor into standard electrical signals (such as 4-20mADC, etc.) to supply secondary instruments such as indicator alarms, recorders, regulators, etc. for measurement, indication and process regulation.

[0003] Today's pressure transmitters are generally installed on pipelines. Due to the lack of protective measures and the small size of some pipelines, the connection where the pressure transmitter is installed on the pipeline is relatively weak and easily broken by external forces, which affects the service life of the pressure transmitter.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a pressure transmitter with good fixing effect is provided, in order to achieve a more practical purpose. Utility Model Content

[0025] The pressure transmitter body 1 includes a display meter 14 , an explosion-proof glass 16 and a stainless steel housing 15 . The explosion-proof glass 16 is located at the front end of the display meter 14 and is installed on the stainless steel housing 15 .

[0026] Among them, a pair of first mounting blocks 10 and a pair of second mounting blocks 11 are each provided with a pair of first thread grooves 12 on both sides, the first thread grooves 12 are internally threadedly connected with first bolts 13, and the first bolts 13 penetrate and connect the first mounting blocks 10 and the second mounting blocks 11, and engage with the first mounting blocks 10 and the second mounting blocks 11. By providing the first bolts 13, the upper fixing ring 7 and the lower fixing ring 9 can be effectively fixed.

[0027] Among them, the clamping mechanism includes a second thread groove 17, a second bolt 18, a knob 19 and a pressure plate 21. The second bolt 18 is threadedly connected to the second thread groove 17, and the second bolt 18 passes through the top of the upper fixing ring 7. The bottom end of the second bolt 18 is connected to the pressure plate 21, and the top end of the second bolt 18 is fixedly connected to the knob 19.

[0029] The working principle of this embodiment:

[0030] During installation, the utility model aligns the two ends of the auxiliary installation pipe 3 with the pipe to be installed and welds them. After the pressure transmitter body 1 is fixed, the first connecting rod 6 and the second connecting rod 8 are moved, and the upper fixing ring 7 and the lower fixing ring 9 are aligned with the nearby pipes for clamping. When the upper fixing ring 7 and the lower fixing ring 9 wrap the pipes near the pressure transmitter, the first mounting block 10 and the second mounting block 11 are threadedly connected by the first bolt 13. When the upper fixing ring 7 and the lower fixing ring 9 clamp the pipes near the pressure transmitter, the knob 19 is rotated to make the second bolt 18 move downward through the second threaded hole. The downward movement of the second bolt 18 makes the pressure plate 21 press against the clamped pipe, so that the upper fixing ring 7 and the lower fixing ring 9 can clamp the pipe more firmly, so that the pressure transmitter can be stable, thereby improving the service life of the pressure transmitter.
