Embodiment 1

[0034] Such as figure 1 As shown, the main body of the rubber hose combustion performance testing device for liquefied petroleum gas transportation of the present invention is a box structure (i.e. reaction box 1), and the reaction box 1 is provided with hose fixing tool 3, Bunsen burner 5 and fuel line. The hose fixing tool 3 is used to fix the rubber hose 4 to be tested and make the rubber hose 4 bend. The rubber hose 4 is filled with liquefied petroleum gas, and the two ends of the rubber hose are blocked with caps 2 . The Bunsen burner 5 is located directly below the curved rubber hose. In order to meet the standard requirements for flame coverage, the inner diameter of the flame mouth of the Bunsen burner 5 is controlled to be 10mm. The fuel pipeline is used for the fuel supply of the Bunsen burner 5, and the fuel pipeline is provided with a pressure regulating valve 7. The fixed tooling set in the reaction box can effectively fix the rubber hose to be tested and keep ...

Embodiment 2

[0036] On the basis of embodiment 1, further as figure 1As shown, the present invention can also be extended to the scheme of embodiment 2. That is: the main body of the rubber hose combustion performance testing device for liquefied petroleum gas transportation of the present invention is a box structure (i.e. reaction box 1), and the reaction box 1 is provided with hose fixing tool 3, Bunsen burner 5 and fuel pipeline. The hose fixing tool 3 is used to fix the rubber hose 4 to be tested and make the rubber hose 4 curved. Preferably, but not limited to, the rubber hose 4 can be bent into a U shape, and the bending radius can be set to 10-15 times the outer diameter. Preferably but not limitatively, the hose fixing tool 3 can include a hose clamp structure, and the hose clamp can move up and down along the corresponding guide rails (not shown in the figure), so as to ensure that the rubber hose 4 to be tested is consistent with the Bunsen The distance of the outer flame of ...

Embodiment 3

[0039] Embodiment 3 The test method for the combustion performance of the rubber hose used for the transportation of liquefied petroleum gas, in addition to using the test device in the aforementioned device embodiment, also includes the following steps:

[0040] Step 301, bend the rubber hose 4 to be tested filled with liquefied petroleum gas into a U shape and fix it in the reaction box 1 through the hose fixing tool, and seal the two ends of the rubber hose with caps 2 . Specifically, one end of the rubber hose 4 can be sealed with the cover 2, and civil power diesel (straight-chain alkane) is injected into the rubber hose 4 (rubber material conforming to the ISO1817 standard) from the other end, and the diesel oil is completely filled with the rubber hose 4 to be tested. Utilize capping cap 2 after pipe 4 to block the other end of rubber hose.

[0041] Step 302, fix the two ends of the rubber hose 4 to be tested on the hose fixing tool 3 respectively, and bend them into a ...

Abstract

The invention discloses a device for testing the combustion performance of a rubber hose for conveying liquefied petroleum gas. The main body of the testing device is of a box body structure, and the testing device comprises a hose fixing tool for fixing the rubber hose to be tested and enabling the rubber hose to be bent, wherein the rubber hose is filled with the liquefied petroleum gas, and the two ends of the rubber hose are blocked; a Bunsen burner which is located under the rubber hose, wherein the inner diameter of a flame opening of the Bunsen burner is 10 mm; and a fuel pipeline which is used for supplying fuel to the Bunsen burner, wherein a pressure regulating valve is arranged on the fuel pipeline. The invention further discloses a method for testing the combustion performance of the rubber hose for conveying the liquefied petroleum gas. According to the testing device and the testing method, the combustion performance of the rubber hose can be effectively tested, so that the safety requirement in the liquefied petroleum gas conveying process is fully met, and accidents are avoided.

Description

technical field [0001] The invention relates to the field of equipment detection, in particular to a device and method for testing the combustion performance of a rubber hose used for transporting liquefied petroleum gas. Background technique [0002] During the existing liquefied petroleum gas loading and unloading operations, some refining and chemical enterprises use rubber hoses to connect the pallet with the tanker. The commonly used rubber hose is generally composed of three layers of materials: from the inside to the outside, it contains the first layer of n-pentane-resistant rubber lining layer, the second layer of braided or wound steel wire reinforcement layer, and the third layer of wear-resistant and outdoor exposure-resistant rubber outer covering. At present, most enterprises use metal universal joints (ie, crane tubes) for loading and unloading of liquefied hydrocarbons. Compared with metal universal joints, rubber hoses have different degrees of difference i...
