Automatic opening and closing pressure control device of horizontal normal-pressure hot water boiler

Abstract

The invention discloses an automatic opening and closing pressure control device of a horizontal normal-pressure hot water boiler. The automatic opening and closing pressure control device comprises a boiler body, openings are formed in the two ends of the boiler body, a first pressure control structure is arranged at the position of the opening in the right side, a second pressure control structure is arranged at the position of the opening in the left side, the boiler body is cylindrical and horizontal, vertical frame rods are symmetrically arranged at the bottom end of the boiler body, a liquid drainage port is formed in the middle of the bottom of the boiler body, and the outer wall of the boiler body is further wrapped with a waste heat recovery device; and the first pressure control structure comprises a sealing cover plate, a pressing cover is arranged at the inner end of the sealing cover plate, the inner side of the pressing cover is connected with a column core block, the column core block is a cylinder, strip-shaped grooves are formed in the upper side and the lower side of the column core block, first sliding blocks are embedded into the strip-shaped grooves, and first pneumatic cylinders are symmetrically arranged on the outer wall of a pressing plate. The internal pressure is adjusted through the first pressure control structure and the second pressure control structure on the two sides of the boiler body, and the device is simple in structure and practical.

Description

technical field [0001] The invention relates to the technical field of hot water boiler equipment, in particular to an automatic opening and closing pressure control device for a horizontal atmospheric pressure hot water boiler. Background technique [0002] Boiler refers to the equipment that uses various fuels, electricity or other energy sources to heat the liquid contained in it to a certain parameter and output heat energy to the outside. Its scope is defined as pressurized steam boilers with a volume greater than or equal to 30L; pressurized hot water boilers with outlet water pressure greater than or equal to 0.1MPa (gauge pressure) and rated power greater than or equal to 0.1Mw; organic heat carrier boilers. Hot water boilers include electric hot water boilers, fuel-fired hot water boilers, gas-fired hot water boilers, and coal-fired hot water boilers. Hot water boilers are boilers that produce hot water. , solar energy, etc.) A thermal energy device that heats wate...
