Abstract

The utility model discloses a high rise heating zoning device, comprising a supercharge pump, outer net water supply is interconnected with the supercharge pump, an inverted valve and an entry of heating high area in sequence, an exit of the heating high area is connected with a reducing valve and a switch valve in series and sequence, an exit of the switch valve is interconnected with outer net backwater, a bypass and a control end of the switch valve is interconnected between the supercharge pump and the inverted valve, a valve is installed at the bypass, a heating low plate is respectively interconnected with the outer net water supply and the outer net backwater, a water current switch is installed at a water supply line of the outer net, and a control casing is interconnected with the supercharge pump. The utility model employs the switch valve instead of an electromagnetic valve, thus the supercharge pump is shutdown and pressure of the control end of the switch valve is repealed and shutdown quickly when power supply is suddenly broken during heating process, therefore the pressure of the low area is not too high.

Description

High-rise heating districting device

Technical field

The utility model relates to a kind of heating plant, is a kind of high-rise heating districting device specifically.

Background technology

At present, it is 03210909.1 heating districting device for high-rise buildings that Patent Office of State Intellectual Property Office discloses the patent No., it has adopted magnetic valve to close high district backwater, magnetic valve drives by solenoid, damaged by voltge surge easily, the circulation coefficient is little, and the operating pressure difference is also very little, easily low district heat dissipation equipment is caused damage.

Summary of the invention

The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, and a kind of reliable operation is provided, high-rise heating districting device with low cost.

In order to achieve the above object, the technical solution adopted in the utility model is: outer net supplies water and joins with the high inlet of distinguishing of booster pump, non-return valve and heating successively, connect successively pressure-reducing valve and open and close valve of the outlet in the high district of heating, the outlet and the outer net backwater that open and close valve join, bypass is arranged between booster pump and the non-return valve and open and close the valve control end and join, mounted valve in the described bypass, the low district of heating supplies water with outer net respectively and the outer net backwater joins, water flow switch is installed on the outer net water supply line, and control cabinet and booster pump join.

The utility model has the advantages that:

Because the utility model has adopted the keying valve to replace magnetic valve, except operate as normal, when cutting off the power supply suddenly in the heating process, booster pump quits work, and opens and closes valve control end pressure and cancels, and closes rapidly, has avoided low district hypertonia.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is the schematic diagram of another embodiment of the utility model;

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

By Fig. 1-Fig. 2 as can be known, the utility model comprises booster pump 1, the inlet that outer net supplies water successively with the high district 5 of booster pump 1, non-return valve 4 and heating joins, connect successively pressure-reducing valve 2 and open and close valve 3 of the outlet in the high district 5 of heating, the outlet and the outer net backwater that open and close valve 3 join, bypass is arranged between booster pump 1 and the non-return valve 4 and open and close valve 3 control ends and join, mounted valve 8 in the described bypass, the low district 6 of heating supplies water with outer net respectively and the outer net backwater joins, water flow switch 9 is installed on the outer net water supply line, and control cabinet 7 and booster pump 1 join.

The utility model is provided with by booster pump 11, the subsidiary loop that non-return valve 12 is formed, and valve 10 is connected booster pump 11, and between the non-return valve 12, an other end is connected the control end that opens and closes valve 3.

Between described booster pump 1 and the non-return valve 4 and open and close mounted valve 14 in the bypass that valve 3 control ends join, valve 14 and open and close and between the valve 3 bypass to be set and the outer net backwater joins, mounted valve 15 therebetween, and the heating height is distinguished 5 inlet duct place setting pressure tables 13, and joins with control cabinet 7.

Can realize by above structure, when water flow switch 9 has water by adhesive, control cabinet 7 control booster pumps 1 start, High-Pressure Water passes pressure to opening and closing valve 3 control ends by valve 8, it is opened rapidly, pressure-reducing valve 2 is adjusted to suitable aperture, the backwater in the high district 5 of heating is through pressure-reducing valve 2 and open and close valve 3, flow into the outer net water return pipeline, realize that high district's heating flow and design discharge are identical.By booster pump 11, the subsidiary loop that non-return valve 12 is formed plays standby effect.

When the Dang Gao district is highly higher, when heating work stops, for preventing to infiltrate air in the pipeline, booster pump 1 is made VFC, limit the pressure upper and lower limit by Pressure gauge 13, like this, booster pump 1 is by distinguishing 5 automatic water supplements to the heating height, the high district of heating 5 pressure are maintained within a certain range all the time, prevent to infiltrate in the pipeline air.
