DETAILED DESCRIPTION

[0024] In order to better understand the purpose, structure and function of the present application, the present application will be further described in detail below in combination with the drawings.

[0025] As shown in Figures 1-5 The present application provides a technical solution: a pressure relief folding breathing pipe system, comprising a plurality of breathing pipelines 1 and a support 2, a plurality of breathing pipelines 1 are arranged vertically side by side, the support 2 is in the shape of a "mouth", a plurality of fixed clamps 3 are arranged on the top outside of the support 2, a plurality of first clamps 4 are rotatably arranged on the outside of the bottom of the support 2 through a rotating shaft, a plurality of first clamps 4 are respectively detachably connected with a plurality of breathing pipelines 1, and the support 2 is detachably connected with a plurality of breathing pipelines 1 through a plurality of fixed clamps 3 on the top;

[0026] A second clamp 8 is arranged above the breathing pipeline 1, and a pull rod 7 is rotatably mounted behind the second clamp 8 through a rotating shaft;

[0027] When the pipeline system is in use, the support 2 can be connected with a plurality of pipelines through the first clamp 4 and the fixed clamp 3, and when the breathing pipeline 1 needs to be folded, the fixed clamp 3 can be separated from the breathing pipeline 1, then the pipeline above the breathing pipeline 1 can be pulled to a horizontal state from a vertical state through the pull rod 7, and then the breathing pipeline 1 can be supported by the pull rod 7, so that the staff can maintain the breathing pipeline 1 conveniently, and the risk of climbing high is avoided.

[0028] In the embodiment, the pull rod 7 is a pull rod, and the outer surface of the inner rod is a rough surface. By designing the pull rod 7, the pull rod 7 can be adjusted to a suitable angle to support the breathing pipeline when the breathing pipeline 1 is pulled to change to a horizontal state, so as to facilitate the maintenance of the staff.

[0029] In the embodiment, the breathing pipeline 1 and the fixed breathing pipeline 5 are two pipelines, and the two pipelines are sealedly connected through a pressure relief folding valve 9 by a flange.

[0030] In the embodiment, the top of the breathing pipeline 1 is provided with a breathing valve 10. When the oil and gas pressure in the pipeline is in a pressure environment of 2 to 3 kilopascals, the breathing valve 10 can automatically open to exhaust, and when the oil and gas pressure in the pipeline is between 1.5 to 2 kilopascals, the breathing valve 10 is closed to be isolated from the atmosphere.

[0031] In the embodiment, the safety valve 6 is arranged on the pressure relief folding valve 9, the safety valve arranged on the pressure relief folding valve 9: the air pressure of the breathing valve 10 at the top of the normal ventilation pipe is 2-3 kPa, when the oil gas pressure of the ventilation pipe reaches the exhaust pressure value, the breathing valve 10 is opened to protect the underground oil tank; since the breathing valve is arranged at a high position, when the breathing valve fails, personnel are not easy to find, which leads to the increase of the pressure in the underground oil tank and damages the oil tank, thereby leaving a safety hazard and economic loss, when the pressure reaches 3 kPa or above, the safety valve 6 of the pressure relief device is automatically opened to balance the internal and external pressure, protect the oil tank, and reduce the safety hazard.

[0032] In the embodiment, the material of the support 2 is aluminum, which can prevent static electricity.

[0033] In the embodiment, the breathing valve 10 is matched with a fire cap 11, which is used to cut off the fire source.
