Pressure regulating device used for water supply and degassing of boiler

Abstract

The invention discloses a pressure regulating device used for water supply and degassing of a boiler. The pressure regulating device comprises a mixing cylinder mixing steam and water, a hollow pipeline is arranged in the mixing cylinder, an opening tubular container is communicated below the hollow pipeline, the diameter of the tubular container is larger than that of the hollow pipeline, a water reservoir is arranged below the tubular container, both the tubular container and the water reservoir are arranged in the mixing cylinder, the top of the mixing cylinder is communicated with a steam inlet pipe and a water inlet pipe respectively, a first gate plate is arranged on the steam inlet pipe, a second gate plate is arranged on the water inlet pipe, a pressure regulator is arranged on a gas exhaust pipe and comprises an elastic membrane, the elastic membrane is connected with the first gate plate, the first gate plate is connected with the second gate plate, and the elastic membrane, the first gate plate and the second gate plate make up a connecting rod mechanism. The pressure regulating device aims to solve the problems that device circuit connection is complicated and cost is high due to pressure is regulated by the aid of circuit management in an existing water supply and degassing system of the boiler.

Description

technical field [0001] The invention relates to safety equipment for boiler production, in particular to a pressure regulating device for boiler water supply degassing. Background technique [0002] The boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in the fuel, and the boiler outputs steam, high-temperature water or organic heat carrier with certain heat energy. The original meaning of the pot refers to the water container heated on the fire, and the furnace refers to the place where fuel is burned. The boiler includes two parts: the pot and the furnace. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's life, and can also be converted into mechanical energy through a steam power device, or converted into electrical energy through a generator. Boilers that provide hot water are called hot water boilers, which are mai...
