The head of the glass fiber reinforced plastic tank

Abstract

The invention provides a seal head of a glass fiber reinforced plastic tank cylinder. The inner surface of a seal head base body is in a perfect circle shape, and a plurality of protrusions diverging from the circle center direction to the periphery are arranged on the inner surface of the seal head base body; the longitudinal sections of the protrusions are in a circular arc shape, an opening is located at the position of the protrusion with the largest width, and the width ranges from 100 mm to 150 mm; the beginning ends, close to the circle center, of the protrusions are all located on the same inner circle, and the inner circle and the edge of the inner surface of the seal head base body form concentric circles; the widths of the protrusions on the same inner circle are equal, and a plurality of circular-arc ribs are arranged at the position, between two adjacent protrusions, of the base body inner surface; the longitudinal section shape and the opening width of the circular arc ribs are consistent with those of the protrusions; and the circular-arc ribs are connected with the protrusions. Under various difference conditions of the number, the position, the area and the like, the seal head can achieve the stress reduction effect superior to that of the prior art, and the compressive strength and safety coefficients of the seal head are improved.

Description

technical field [0001] The invention relates to the technical field of head production of glass fiber reinforced plastic tanks, in particular to a head of glass fiber reinforced plastic tanks. Background technique [0002] Water is an essential and important material for the survival of human beings and all living things, and an extremely precious natural resource that cannot be replaced by industrial and agricultural production, economic development and environmental improvement. In a broad sense, water resources refer to the total amount of water in the hydrosphere, surface water and groundwater that have use value and economic value for human activities. Surface water can include rivers, lakes, and aquaculture waters. The main natural source is the catchment water. Precipitation in the area and surface runoff in this catchment area. In many parts of the world, the demand for water has exceeded the capacity of water resources. Due to the large population of our country, t...
