Embodiment 1

[0020] The main structure of the safety protection device for preventing pipeline leakage involved in this embodiment includes: a first pulley 1, a through hole 2, a second pulley 3, a steel cable 4, a central shaft 5, a steel cable casing 6, a switch knob 7, Fix the shell 8; the diameter of the first pulley 1 is 15-40mm, and the thickness is 5-15mm. A groove around the circumference of the first pulley 1 is arranged on the outer peripheral surface, and the width of the groove is 3-10mm. The size of the first pulley 1 matches the steel cable 4 and can accommodate the steel cable 4. The center of the first pulley 1 is provided with a through hole 2. The shape of the through hole 2 matches the main switch of the pipeline. The through hole 2 is set on the main switch of the pipeline and can Drive the main switch of the pipeline to rotate synchronously, the material of the first pulley 1 is metal or plastic; the size and material of the second pulley 3 are the same as that of the f...

Embodiment 2

[0027] The main structure of the safety protection device for preventing pipeline leakage involved in this embodiment is the same as that of Embodiment 1, the steel cable 4 adopts a brake line, the steel cable sleeve 6 is a bendable metal tube, and the first pulley The through hole 2 of 1 is in-line or butterfly shape, and the corner radius of the cable casing 6 at the corner of the cable 4 line is 120 mm or more.

[0028] Further, the brake line is made of high carbon steel with a specification of 1×12.

[0029] Further, the cable casing 6 is a brake line casing.

[0030] Further, the preload of the cable is 4 lbs.

Embodiment 3

[0032] The main structure of the safety protection device for preventing pipeline leakage involved in this embodiment is the same as that of Embodiment 1. The device is applied to indoor gas pipelines and installed on the main switch of the gas pipeline and the ignition stove to prevent gas leakage. Knob 7 is installed on the ignition stove top or the stove cabinet wall, etc., where it is easy to touch. The through hole 2 of the first pulley 1 is set on the gas pipeline master switch, and the fixed shell 8 is fixed on the cabinet wall, wall or pipeline. The steel cable sleeve 6 is fixed on the fixed shell 8, and the steel cable 4 covered with the steel cable sleeve 6 is wrapped around the first pulley 1 and the second pulley 3; when it is necessary to open the main switch of the pipeline, turn the switch knob 7 counterclockwise , the switch knob 7 drives the second pulley 3 to rotate through the central shaft 5, the second pulley 3 drives the steel cable 4 to rotate synchronous...

Abstract

The invention belongs to the technical field of pipeline master switch control, and relates to a safety protection device for preventing pipeline leakage. The main body structure of the safety protection device comprises a first pulley, a through hole, a second pulley, a steel cable, a central shaft, steel cable sleeves, a switch knob and fixing shells, wherein the through hole sleeves a pipelinemaster switch and can drive the pipeline master switch to rotate synchronously; the size of the second pulley is the same as the size of the first pulley; the central shaft fixed with the second pulley is vertically arranged at the center of the second pulley, and the other end of the central shaft is installed and fixed at the center of the bottom of the switch knob; the four ends of the two steel cable sleeves are fixed to a cabinet wall, a wall or a pipeline through the fixing shells or pipe clamps; and the two steel cable sleeves respectively sleeve the parts, in the two transmission directions, of the steel cable. The safety protection device is convenient and labor-saving to operate, capable of reducing the risk of the pipeline leakage and being installed and modified integrally, good in flexibility, low in popularization cost, simple in overall structural design, safe and reliable to use, good in universality and friendly in application environment.

Description

Technical field: [0001] The invention belongs to the technical field of pipeline main switch control, and relates to a safety protection device for preventing pipeline leakage, in particular to a device for controlling the pipeline main switch at a relatively long distance. The operation knob of the safety protection device is easily accessible and easy to operate and use. Background technique: [0002] Natural gas, as a high-quality, clean and efficient green energy, is the energy that is promoted and popularized by the national energy policy; natural gas directly enters thousands of households in the city through natural gas pipelines, and the pipeline is continuously transported without the trouble of cutting off gas and replacing cylinders. It also does not need to be stored or added on site, which greatly facilitates residential users. However, natural gas is toxic. When the content in the air reaches a certain level, the oxygen in the air will not be enough to sustain ...
