Track type hose suitable for oil tank floating roof water drainage

Abstract

The invention discloses a track type hose suitable for oil tank floating roof water drainage. A water containing mechanism arranged on the top of an oil tank is included. The lower portion of the water containing mechanism communicates with a main pipeline, and meanwhile the bottom of the main pipeline is provided with a plurality of sets of water drainage hoses. Each water drainage hose comprisesa first rubber pipe layer on the inner layer and a second rubber pipe layer which is in cup joint to the outer portion of the first rubber pipe layer, wherein a spiral pipe layer is in cup joint between the first rubber pipe layer and the second rubber pipe layer, meanwhile, the outer portion of the second rubber pipe layer is in cup joint with a stainless steel corrugated pipe sleeve, and the stainless steel corrugated pipe sleeve is formed through mutual cup joint of annular corrugated casing pipes. The spiral pipe layers are arranged in the provided water drainage hoses, memory springs arearranged on the inner walls of the spiral pipe layers, through the recovery memorizing function of the memory springs, in the floating roof up-down moving process, the water drainage hoses where thespiral pipe layers are located can recover to the original shape, and the situation that the water drainage hoses are mutually wound, and the water passing performance of the water drainage hoses is influenced is avoided.

Description

technical field [0001] The invention belongs to the technical field of drainage hoses, in particular to a trajectory hose suitable for floating roof drainage of oil tanks. Background technique [0002] With the continuous development of science and technology, petrochemical work is an important part of the chemical industry and one of the pillar industries of the industry. It plays an important role in the development of the national economy. Crude oil undergoes cracking (cracking), reforming and separation. Provide basic raw materials, such as ethylene, propylene, butene, butadiene, benzene, toluene, xylene, naphthalene, etc. As the main supply link of energy, petrochemical industry plays an important role in industry, agriculture and scientific research. [0003] At the same time, in the petrochemical production process, the oil tank is an important device for oil storage, and its top is equipped with a floating roof. According to the amount of oil stored, the relative po...

Problems solved by technology

[0004] Although this method can play a certain drainage function, the drainage pipe used is a metal pipe with a limited service life, and the hinged connection between the metal pipes is also prone to failure, which often makes it difficult to effectively remove the accumulated water at the top. In addition, rubber tubes can also be used directly for replacement. However, when the rubber tubes are replaced, because the relative position of the floating roof will change, a long pipeline is usually reserved for the bottom of the floating roof. When changing the position, ordinary rubber tubes have a certain degree of elasticity and are easily entangled with each other, causing the drainage channel in the rubber tube to be blocked and affecting the normal drainage function
