Problems solved by technology

Since the RTD and the bolt are fixed together, when the bolt is tightened, the RTD is rotated together and the cable is rotated, causing the cable connector to be stressed, and the cable connector will be twisted off after long-term operation

Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] As shown in the figure, the anti-overflow and anti-rotation bolts include bolt one and bolt two. There is a threaded hole in the head of bolt one, and light holes are set in the screw part of bolt one and bolt two. The light hole in the screw part of bolt one A sheath is sheathed in the hole, the threaded hole on the head of the bolt 1 is set in cooperation with the screw part of the bolt 2, and a movable hoop is arranged in the light hole of the bolt 2, and the movable hoop is a ring with an opening on one side.

[0020] Further, the first bolt, the second bolt, the sheath, and the movable hoop are all sleeved on the mounted part, wherein the mounted part can be an RTD, or other mounting parts that require overflow prevention during disassembly and anti-rotation during disassembly.

[0021] Further, the outer diameter of the m...

Abstract

The invention relates to an overflow and rotation preventing bolt and an application method thereof. The overflow and rotation preventing bolt comprises a first bolt body and a second bolt body. A threaded hole is formed in the head of the first bolt body, and unthreaded holes are formed in a screw part of the first bolt body and the second bolt body. A protection sleeve is sleeved with the unthreaded hole in the screw part of the first bolt body, and the threaded hole in the head of the first bolt body and a screw part of the second bolt body are arranged in a matched manner. A movable hoop is arranged in the unthreaded hole of the second bolt body in a matched manner, and the movable hoop is a circular ring with one side opened. By means of the overflow and rotation preventing bolt, overflow and rotation prevention on an installing piece needing overflow prevention during detaching and needing rotation prevention during dismounting and mounting can be achieved, meanwhile, the structure is simple, and stability and reliability are achieved.

Description

technical field [0001] The invention relates to an anti-overflow anti-rotation bolt and a using method thereof. Background technique [0002] RTD (abbreviation for Resistance Temperature Detector) is a resistance temperature detector, referred to as thermal resistance. RTD is actually a special wire whose resistance changes with temperature. Usually RTD materials include copper, platinum, nickel and nickel / iron alloy. The RTD element can be a wire or a thin film, which is electroplated Or sputtering method coated on the ceramic material substrate. [0003] Bolts are fixed on the RTD. When installing the RTD on the pressurized oil pipeline or the pressurized water pipeline, it is necessary to drill holes in the pipeline, install the RTD, and tighten the bolts to stop the oil or water. Since the RTD and the bolts are fixed together, when the RTD is inspected and replaced, the pipeline needs to be depressurized and emptied before the RTD can be removed. [0004] In addition,...
