Problems solved by technology

The three types of boilers have limitations and cannot be used universally
[0010] Generally, the boilers sold in the market can only realize one of the above three pressure modes, and no boiler can realize the above three pressure modes or freely switch the three pressure modes

Embodiment Construction

[0033] Combine below figure 1 with figure 2 , the present invention is further described:

[0034] Such as figure 1 As shown in the figure, a full-pressure boiler can be freely switched between three pressure modes: normal pressure, negative pressure and pressure.

[0035] Its structure is as follows: the full-pressure boiler includes a burner 1 and a steam chamber 2, and a condenser 11 is provided at the outlet of the burner 1, which is used for heat exchange with flue gas. The burner 1 is connected with the steam chamber 2 and heats the water in the steam chamber 2 or heats it into steam. The inlet end of the steam chamber 2 is provided with a main steam valve 22 , and the outlet end of the steam chamber 2 is provided with a water supply valve 23 . The steam chamber 2 is provided with a pressure gauge 21 and a full-pressure switching safety valve 3 , and the switching of the three pressure modes of the steam chamber 2 , normal pressure, negative pressure and under press...

Abstract

The invention relates to a full-pressure switching safety valve and a full-pressure boiler using the full-pressure boiler, characterized in that: the full-pressure boiler realizes free switching among three pressure modes of normal pressure, negative pressure and bearing pressure. The present invention can well combine the characteristics of three types of boilers: negative pressure (vacuum) boiler, normal pressure (no pressure) boiler, and pressure-bearing boiler, realize functional coverage, switch conveniently according to needs, and realize A true unity of three in one.

Description

technical field [0001] The invention relates to a safety valve and a boiler using the same, in particular to a full-pressure switching safety valve integrating three functions of negative pressure, normal pressure and pressure bearing and a full-pressure boiler using the same. Background technique [0002] Boilers can be divided into the following three types of boilers according to the pressure in the furnace: [0003] 1. Pressure boiler; [0004] A pressure boiler is a closed boiler that we usually see, and the pressure in the boiler is usually greater than a standard atmospheric pressure. The steam-water system in the boiler is composed of airtight containers and pipes, and is heated by flames, and bears fluid pressure during work, which belongs to special equipment. [0005] 2. Atmospheric pressure boiler; [0006] Atmospheric boilers are pressureless boilers, which refer to boilers with zero gauge pressure of water vapor in the boiler, that is, boilers that operate u...
