High-pressure water storage tank with small heat influence in arid region

Abstract

The invention discloses a high-pressure water storage tank with small heat influence in an arid region. The high-pressure water storage tank comprises a tank body; supporting legs are welded to the bottom of the tank body; a water injection opening is welded to the outer surface of the left side of the tank body; a pressure reducing valve is fixedly connected to the right side of the water injection opening; the pressure reducing valve is welded to the outer surface of the tank body; a water outlet is welded to the outer surface of the right side of the tank body; a pressure indicating gauge is welded to the front face of the tank body; the tank body comprises an outer tank; and an inner tank is arranged in the outer tank. According to the high-pressure water storage tank with the small heat influence in the arid region, the tank body is designed to be of a double-layer structure and is divided into the outer tank body and the inner tank body, a limiting block is arranged between the outer tank body and the inner tank body, a gap between the outer tank body and the inner tank body can be filled with water while the limiting block plays a role in limiting and fixing, and most heat is absorbed according to the principle that the specific heat capacity of water is large; and the problems that a traditional water storage tank body is only provided with one layer, and internal water is prone to temperature rise are solved.

Description

technical field [0001] The invention relates to the technical field of water conservancy, in particular to a high-pressure water storage tank with little thermal influence in arid areas. Background technique [0002] Water storage tank is a kind of metal tank for storing water resources. It is divided into vertical and horizontal. Water storage tanks are widely used all over the world due to their good sealing, simple manufacturing process and high stability, especially in water shortages. In arid areas, water storage tanks have great advantages. [0003] Under normal circumstances, arid areas with scarce water resources are under high temperature all year round. Due to their large volume, the water storage tanks can only be placed outdoors. Since the traditional water storage tanks are all single-layer metal structures, they are exposed to high temperatures for a long time. Under the circumstances, the high thermal conductivity of the metal will increase the volume of the ...

Problems solved by technology

[0003] Under normal circumstances, arid areas with scarce water resources are under high temperature all year round. Due to their large volume, the water storage tanks can only be placed outdoors. Since the traditional water storage tanks are all single-layer metal structures, they are exposed to high temperatures for a long time. Under the circumstances, the high thermal conductivity of the metal will increase the volume of the water and gas inside the tank due to the thermal expansion effect, resulting in an increase in the internal pressure of the tank. For the water storage tank installed with a pressure indicator, the abnormal internal pressure will cause It will make it impossible for external operators to accurately know the volume of water in the tank, which will have an impact on daily life and production. Some water storage tanks will add a separate pressure stabilization mechanism outside. Although the influence of temperature on the tank can be controlled, the usual stability The pressure mechanism needs to provide a separate energy source, which increases energy loss and increases the volume of the tank
