Abstract
The utility model relates to a boiler water-feeding device for filling the water to a steam boiler by the gravity action, comprising a pressure withstand steam and water pot, a plurality of valves and pipelines. The utility model can omit the water-feeding pump and a standby steam reciprocating pump of the existing boiler water-feeding device. The utility model has the advantages of simple structure, saving electricity, low cost, high safety, convenient maintenance, etc.
Description
The utility model relates to a kind of boiler feedwater device that relies on the gravity effect to the steam boiler water filling.
At present, the centrifugal feed pump of the main use of steam boiler feedwater must be used motor-driven, also must set up a donkey pump, prepares against when having a power failure and uses.Not only consuming electric power is big, the equipment complexity, and the cost height, but also must take ground, boiler room.
The purpose of this utility model is to provide a kind of power consumptive province, simple in structure, easy operating, easy to maintenance and boiler feedwater device that also can operate as normal when having a power failure suddenly.
Technical solution of the present utility model is: form the boiler feedwater device by a withstand voltage air hydraulic cylinder and some valves.Pick out a feed pipe of using to the boiler water filling from the bottom of withstand voltage air hydraulic cylinder.A non-return valve is installed on feed pipe; Pick out a vapor communication pipe from the top of air hydraulic cylinder.A stop valve is installed on the vapor communication pipe.Pick out a upper hose again from air hydraulic cylinder, on upper hose, adorn a stop valve.When the utility model uses.Air hydraulic cylinder is installed on appropriate position, boiler top by bearing support.The vapor communication pipe is connected with drum from the top.Feed pipe is connected with the boiler feedwater mouth.Upper hose is connected with running water pipe or water pump.Method of operating is: close the stop valve on the vapor communication pipe.Stop valve on the breakdown upper hose.Add water by upper hose to air hydraulic cylinder.Close the stop valve on the upper hose after waiting to fill.Stop valve on the breakdown vapor communication pipe.Boiler drum is communicated with air hydraulic cylinder, and the interior pressure of air hydraulic cylinder equates with pressure in the drum.At this moment, because air hydraulic cylinder is positioned at drum top eminence, the water in the air hydraulic cylinder flows in the drum through non-return valve from feed pipe under the gravity effect, reaches to the boiler feedwater purpose.Close the stop valve on the vapor communication pipe, communicating pipe is blocked, and pressure will disappear in the air hydraulic cylinder, and the stop valve on the breakdown upper hose can add water again in air hydraulic cylinder.
The utility model has the advantages that: whole device is made up of withstand voltage air hydraulic cylinder and several valves.Compare with existing waterworks, simple in structure.Not fragile.Maintenance cycle is long; The utility model only consumes small amount of electrical energy when adding water to air hydraulic cylinder and carry out control automatically, power savings is remarkable, and when having a power failure, also can guarantee safety work with manual operation, does not need to be equipped with donkey pump.Equipment manufacturing cost is low.The utility model is installed on the boiler top, need not take ground, boiler room, saves floor space.
Accompanying drawing is structure of the present utility model and installs and uses schematic diagram.
Air hydraulic cylinder 1 manufactures and designs by low grade pressure vessels manufacturing technology condition among the figure.Its withstand voltage properties will adapt with boiler pressure with supporting, and volume should satisfy the once maximum confluent of boiler.Bottom at air hydraulic cylinder 1 connects a feed pipe 2 of using to boiler drum 4 water fillings, a non-return valve 3 is installed on the feed pipe 2, be used for preventing that the water of drum 4 from flowing backwards to air hydraulic cylinder, the top of air hydraulic cylinder 1 connects a vapor communication pipe 5, adorn a stop valve 6 on the vapor communication pipe 5, stop valve 6 can adopt manually operated various stop valve, also can adopt magnetic valve, in order to automatically controlled or be equipped with automatic control system and carry out feedwater control automatically, 8 for to add the upper hose that water is used to air hydraulic cylinder 1 among the figure.Adorn a stop valve 9 on the upper hose, stop valve 9 can be used manually-operated gate, also can adopt magnetic valve, carries out automatically controlled or automatic control, and 7 for monitoring the Pressure gauge of pressing in the air hydraulic cylinder among the figure.10 air bleeding valves for air in the discharging air hydraulic cylinder.When the utility model uses.Air hydraulic cylinder is installed in the appropriate location that is higher than boiler drum by bearing support.Vapor communication pipe 5 is connected with the boiler drum top through stop valve 6.Feed pipe 2 is connected with the boiler feedwater mouth through non-return valve 3.Upper hose 8 is connected with running water pipe or water pump through stop valve 9.Add water to air hydraulic cylinder 1 and also can adopt following structure.Promptly the bottom from air hydraulic cylinder 1 picks out a suction hose 11, a non-return valve or stop valve 12 are installed on the suction hose 11, during use suction hose 11 is led in the boiler blow-down water pond, close after the stop valve 6, when air hydraulic cylinder 1 inner vapor was condensed and produces negative pressure, the water in the back pool 13 was drawn onto in the air hydraulic cylinder automatically by non-return valve 12.Be used for to boiler feedwater.If it is big or when needing to go up water continuously that boiler is once gone up the water yield.Can establish the above-mentioned boiler feedwater device of two covers and carry out alternately upward water, can also can satisfy cauldron feedwater requirement with less air hydraulic cylinder like this.Also can realize continuous water feeding.
Claims (3)
1, a kind of boiler feedwater device, comprise air hydraulic cylinder, valve and connecting line, it is characterized in that a withstand voltage air hydraulic cylinder 1, bottom at air hydraulic cylinder 1 connects a feed pipe 2 that is used for to the boiler water filling, adorn a non-return valve 3 on the feed pipe 2, connect a vapor communication pipe 5, adorn a stop valve 6 on the vapor communication pipe 5 at the top of air hydraulic cylinder 1, on air hydraulic cylinder 1, connect a upper hose 8 again, adorn one on the upper hose 8 and wear only valve 9.
