Abstract
The utility model provides a kind of boiler safety pressure discharge device, it comprises and is arranged on safe row pressure plate on boiler body inwall by coaming plate, described safe row pressure plate, coaming plate and boiler inner wall surround pressure chamber, described safe row pressure plate plate is towards pressure chamber inner recess, and the breakdown strength of described coaming plate is greater than the breakdown strength of safe row pressure plate; Described pressure chamber is communicated with external pressure inlet pipe and relief tube respectively by boiler inner wall, and described external pressure inlet pipe is connected with external pressure source of the gas by Non-return air valve; Described relief tube is connected with air by pressure check valve.
Description
Technical field
The utility model belongs to boiler plant field, relates to a kind of boiler safety pressure discharge device specifically.
Background technology
Existing boiler carrys out pressure release usually through safety valve, because safety valve is often because the reason such as to get rusty there will be fault in reality uses, does not reach the effect of safety relief; Or need often to change safety valve, cost is higher; Usually cause boiler can not safety relief and cause the bursting of boilers, cause great security incident, personnel and social property are damaged.
Utility model content
The purpose of this utility model be just to provide above-mentioned the deficiencies in the prior art part a kind of can effectively pressure release, prevent the boiler safety pressure discharge device of the bursting of boilers.
The utility model realizes the technical scheme that above-mentioned purpose takes: a kind of boiler safety pressure discharge device, it comprises and is arranged on safe row pressure plate on boiler body inwall by coaming plate, described safe row pressure plate, coaming plate and boiler inner wall surround pressure chamber, described safe row pressure plate plate is towards pressure chamber inner recess, and the breakdown strength of described coaming plate is greater than the breakdown strength of safe row pressure plate; Described pressure chamber is communicated with external pressure inlet pipe and relief tube respectively by boiler inner wall, and described external pressure inlet pipe is connected with external pressure source of the gas by Non-return air valve; Described relief tube is connected with air by pressure release check valve.
The exit normal of relief tube described in the utility model is upwards connected with air.
Principle of the present utility model is: the breakdown strength utilizing safe row pressure plate, safe air pressure is filled with by Non-return air valve in pressure chamber, pressure chamber is also communicated with air by relief tube and pressure release check valve, safe pressure in the opening pressure of pressure release check valve and charged pressure chamber adapts, the safe pressure of boiler internal setting is equal with the breakdown strength on pressure chamber sectional area of safe row pressure plate with the safe pressure difference in charged pressure chamber, when the pressure of boiler internal is greater than the safe pressure of setting, the destroyed fracture of row pressure plate, the pressed gas of boiler internal is expelled to air by relief tube and pressure release check valve, the mode that row pressure plate caves in pressure chamber is arranged, increase its direction intensity, prevent row pressure plate from breaking to boiler internal.
The beneficial effect that the utility model takes technique scheme to bring is: the utility model, by taking technique scheme, makes boiler security performance in operation higher, ensure that the safety of surrounding people and social property.
