Utility model content
Technical problem to be solved in the utility model is, for the shortcoming of above prior art, propose a kind of pressure relief device for boiler heating tank, not only structure is simple, cost is low, the problem that can avoid resonates pipes, simultaneously can also saving heat energy, reduces costs, and avoid arranged at safety valve in the condition of high temperature, its service life can be increased, the dirt of heating tank inside can also be discharged simultaneously, improve the quality of equipment.
In order to solve the problems of the technologies described above, the technical solution of the utility model is achieved in the following ways: a kind of pressure relief device for boiler heating tank, comprise heating tank, high pressure valve, magnetic valve, downcomer and transformer, heating tank bottom discharge mouth is connected with high pressure valve water inlet by pipeline, the delivery port of high pressure valve is connected with magnetic valve water inlet by pipeline, magnetic valve delivery port is connected with downcomer, magnetic valve and high pressure valve are by wire and transformer control connection, high pressure valve valve is in normally open, magnetic valve valve is in normally off, and be provided with microswitch in high pressure valve and be connected with solenoid valve control circuit, high pressure valve and magnetic valve and transformer is made to form a normal open circuit.
Like this, pass through the technical solution of the utility model, high pressure valve and magnetic valve are arranged on the discharge outlet place of heating tank lower end, by the impact of gravity in heating process, high-temperature water is in upper end, low-temp water level is in lower end, when internal pressure is excessive, the water at low temperature of lower end discharges heating tank, such saving heat energy, avoid waste, reduce costs, the efficiency of heating surface is high, and the dirt of bottom can also be discharged from discharge outlet, increase water quality, and avoid high pressure valve to be in high-temperature high-pressure state for a long time, can increase its service life like this, reduce costs, and avoid high pressure valve to send the sound resonating and pipe.
The technical scheme that the utility model limits further is:
The aforesaid pressure relief device for boiler heating tank, heating tank upper end is also provided with water inlet pipe, and water inlet pipe is also provided with filter, by filter energy filtering water, avoids blocking.
The aforesaid pressure relief device for boiler heating tank, heating tank is positioned at medium position and is also provided with at least one tap.
The aforesaid pressure relief device for boiler heating tank, between high pressure valve and magnetic valve, pipeline is also provided with pressure transmitter.
The beneficial effects of the utility model are: discharge outlet place high pressure valve and magnetic valve being arranged on heating tank lower end, by the impact of gravity in heating process, high-temperature water is in upper end, low-temp water level is in lower end, when internal pressure is excessive, the water at low temperature of lower end discharges heating tank, such saving heat energy, avoid waste, reduce costs, the efficiency of heating surface is high, and the dirt of bottom can also be discharged from discharge outlet, increase water quality, and avoid high pressure valve to be in high-temperature high-pressure state for a long time, can increase its service life like this, reduce costs, and avoid high pressure valve to send the sound resonating and pipe, water inlet pipe is also provided with filter, by filter energy filtering water, avoids blocking.
