Embodiment 1

[0034] figure 1 A flow chart of a method for vacuuming a vacuum boiler provided by the present invention. like figure 1 As shown, the method of evacuating the vacuum boiler includes:

[0035] Step S10: When the burner and the valve are closed and a predetermined amount of water is added to the boiler, a heating command for heating the water in the boiler is sent to the burner.

[0036] Turn off the burner and valve, add a predetermined amount of water to the boiler, and the burner starts to heat the water in the boiler. While the burner is heating the water in the boiler, the process proceeds to step S11. Among them, there is a sight glass in the middle position of the boiler wall. In order to facilitate observation, the predetermined amount is 1 / 2 of the sight glass. It should be specially pointed out that the predetermined amount in the present invention is not limited to this value.

[0037] Step S11: Monitor the water temperature value sent by the temperature sensor in...

Embodiment 2

[0046] figure 2 It is a structural diagram of a device for evacuating a vacuum boiler provided by the present invention. like figure 2 As shown, the device 1 for vacuuming a vacuum boiler includes:

[0047] The heating command sending unit 10 is configured to send a heating command to the burner to heat the water in the boiler when the burner and the valve are closed and a predetermined amount of water is added to the boiler.

[0048] The heating command sending unit 10 sends a heating command to the burner only when water is added to the boiler, which avoids the dry burning of the boiler, increases the safety of operation, and prolongs the service life of the boiler.

[0049] The heating stop command sending unit 11 is used to monitor the water temperature value sent by the temperature sensor in real time, and when the water temperature value reaches the set target temperature value, send a heating stop command to the burner to stop heating the water in the boiler.

Embodiment 3

[0058] On the basis of the second embodiment, image 3 The structure diagram of a system for evacuating a vacuum boiler provided by the present invention. like image 3 As shown, in addition to the device 1 for evacuating the vacuum boiler in the second embodiment, the system for evacuating the vacuum boiler also includes: a temperature sensor 15 connected to the device 1 for evacuating the vacuum boiler, a vacuum pressure gauge 16, a vacuum exhaust hole 18 and electric controller 14.

[0059] The temperature sensor 15 is arranged on the boiler wall and is used to measure the water temperature value of the water in the boiler.

[0060] The vacuum pressure gauge 16 is arranged on the boiler wall and is used to measure the pressure value in the boiler.

[0061] The vacuum exhaust hole 18 is arranged on the boiler wall, and is used to discharge the steam in the boiler.

[0062] The electric controller 14 is connected to the vacuum vent 18 for controlling the opening and closi...

Abstract

The invention discloses a method for evacuating a vacuum boiler. When the burner and the valve are closed and a predetermined amount of water is added to the boiler, the heating of the burner is controlled, and the water temperature is monitored in real time. When the water temperature reaches the target temperature When the value is set, control the burner to stop heating; after the burner stops heating, control the electric controller to open the vacuum exhaust hole, and monitor the pressure value in the boiler in real time. When the pressure value is lower than the target pressure value, control the electric controller to close the vacuum Vent. The invention avoids the installation of the vacuum pump, saves the production cost, and the increased vacuum exhaust hole provides a special channel for vacuuming, avoids mixing with other channels, and reduces the potential safety hazards when other channels are used as exhaust holes . The valve of the vacuum exhaust hole is automatically opened and closed by the electric controller, which has the advantages of quick response and safety. In addition, the present invention also discloses a boiler, a device and a system corresponding to the above method, and the effect is as above.

Description

technical field [0001] The invention relates to the technical field of hot water boilers, in particular to a vacuum boiler and a method, device and system for vacuuming the vacuum boiler. Background technique [0002] The vacuum boiler is known as a new trend in the field of civil heating and has become a hot-selling device in the market. The difference between this boiler and the traditional hot water boiler is that the boiler operates in vacuum, with high safety and thermal efficiency. The degree of vacuum is also An important factor affecting boiler efficiency. Therefore, in order to ensure the normal operation and thermal efficiency of the boiler, it is necessary to avoid the destruction of the vacuum degree of the vacuum boiler. However, in practical applications, after the vacuum boiler leaves the factory, the problem of vacuum leakage may occur during transportation, sealing, and use. [0003] For the vacuum leakage problem of the vacuum boiler, the solution in the ...
