A full soil tank system with built-in valve chamber

Abstract

The invention relates to a full soil-covered tank system with a built-in valve chamber, which includes: a spherical tank body, a valve chamber and a channel, the outside of the spherical tank body is covered with soil, and the spherical tank body is supported by a column and arranged on the ground, so that the spherical tank body There is a gap between the bottom of the bottom and the ground foundation; the valve chamber is set between the spherical tank and the ground foundation; the top opening of the valve chamber is connected with the bottom of the spherical tank through the first connection structure, so that the valve chamber forms a pair of spherical tanks The support of the bottom; one end of the channel is connected to the side opening of the valve chamber through the second connection structure, and the other end of the channel extends outwards to communicate with the outside of the soil layer; the present invention can accommodate and connect the inside and outside of the tank after the tank is covered with soil. All kinds of pipelines and cables of electronic control equipment can pass through the valve chamber more quickly and cut off the pipeline to the greatest extent in case of emergency; the valve chamber has good sealing performance, which can better protect various facilities inside it.

Description

technical field [0001] The invention relates to the field of soil-covered tanks, in particular to a full-covered soil tank system with a built-in valve chamber. Background technique [0002] Soil-covered storage refers to the pressurized storage of liquefied petroleum gas at room temperature in tanks or under the ground, and reasonable and comprehensive backfilling. This technology is very suitable for storage of flammable and explosive liquid materials, and can The tanks are protected to prevent the heat and shock waves of combustion and explosion from affecting other tanks, which can effectively reduce risks, and the tanks can be installed closer to each other, saving space. At present, the technology of fully covering the tank body with soil is still immature. When the tank body is covered with soil, all kinds of pipelines and cables connecting the inside and outside of the tank, as well as cables for electrical control equipment, need to be laid out and controlled. In pa...

Problems solved by technology

At present, the technology of fully covering the tank body with soil is still immature. When the tank body is covered with soil, the layout control of various pipelines and cables connecting the inside and outside of the tank and electric control equipment is required. In particular, valves need to be installed on the pipelines according to the standard. In case of emergency Therefore, it is necessary to set the valve as close as possible to the tank body, which requires the design and management of the valve chamber structure of the pipeline valve in advance, but the existing valve chamber structure in the full-covered soil is not More often, whether it can withstand the pressure of the upper soil for a long time, and the stress change caused by the settlement and deformation of the soil structure, has become a test for the structure of the valve chamber.
