Plate 9k automatically adjusts electric control valve 2a aperture.By outdoor temp angle value 9w, the confession of two level net, return water temperature are determined.According to two
Level net supply water temperature, two level net return water temperature, one-level net supply water temperature, are automatically adjusted by PLC control apparatus and guidance panel 9k
Electrically operated valve 2a and 9h aperture, one-level net is supplied water after being mixed with two level net backwater so that mixed water meets that two level net supplies
Water requirement.When the adjustable jet pump 9a outlet temperatures of the first order and pressure meet temperature and pressure needed for the water supply of two level net
When, PLC control apparatus and guidance panel 9k close electrically operated valve 9d and 9g automatically, open electrically operated valve 9f；When the first order is sprayed
When pump 9a outlet temperatures 9B and pressure 9C are more than temperature and pressure needed for the water supply of two level net, by PLC control apparatus and operating surface
Plate 9k closes electrically operated valve 9f automatically, opens electrically operated valve 9d and 9g so that mixed water by second level jet pump 9e again
Secondary mixed water is carried out, is fed in heat user.When two level net pressure of supply water value is more than the value set in advance, PLC control apparatus
And guidance panel 9k control magnetic valves 4a is opened and carried out pressure release, until pressure meets to require.
When one-level net supply water temperature raises, adjustable jet pump nozzle needle is moved inward so that the circulation of nozzle is cut
Face reduces, and is reduced by the one-level net water supply flow of nozzle, mixing ratio increase；, will be adjustable when one-level net supply water temperature reduces
Section formula jet pump nozzle needle is displaced outwardly so that the flow area increase of nozzle, by the one-level net water supply flow increase of nozzle, is mixed
Composition and division in a proportion reduces.By the regulation of nozzle needle in jet pump, the temperature change of one-level net and two level net when realizing outside air temperature change.
The operation principle of jet pump is the liquid using higher-energy, and the stream at high speed, sweeping along surrounding is produced by nozzle
Body moves to anemostat together, makes to produce negative pressure in receiving chamber, will by conveying liquid suck receiving chamber, together with high-velocity fluid
Flowed outwardly after being boosted in anemostat.For 9a, the one-level net water supply 9I of HTHP, into jet pump nozzle after low temperature is low
The two level net backwater 9V injections of pressure enter in jet pump so that one-level net water supply 9I and two level net backwater 9V is mixed in jet pump 9a
Close, the mixing water 9III for being met two level net water supply requirement is supplied in user.If mixed coolant-temperature gage and pressure are higher than two
Level net water supply requirement, the water 9II and two level net backwater 9IV of the adjustable jet pump 9a outlets of the first order are adjustable in the second level
Mixed in jet pump 9e, decrease temperature and pressure is met the 9C of secondary network water supply conditions and is supplied in user again.
The pressure of return water value measured according to two level net pressure of return water monitor 6d and one-level net pressure of return water monitor 6e, by
PLC control apparatus and guidance panel 9k adjust automatically one-level net backwater pressure pumps 8a frequency and start and stop.When two level net backwater pressure
It is automatic to close electric control valve 2b when power is less than one-level net pressure of return water, one-level net backwater pressure pump 8a is opened, according to two level net
The flow and lift of pressure of return water and one-level net pressure of return water difference variable frequency adjustment backwater pressure pump 8a；When two level net pressure of return water
It is automatic to close backwater pressure pump 8a during equal to one-level net pressure of return water, open electric control valve 2b so that two level net backwater passes through
Bypass pipe F enters in one-level net return main.
To prevent decompression, when two level net pressure of return water value is too low, closed automatically by PLC control apparatus and guidance panel 9k
Magnetic valve 4a.
In summary, using this programme, can make in heating system the temperature of the adjustable injection pump discharge of the first order and
Pressure opens the adjustable jet pump in the second level by the further pressure and temperature reducing of water not when in the range of two level net water supply requirement,
Protection system it is safe for operation, improve the overall security of heating system, while reduce heating maintenance cost.
It the foregoing is only of the present utility model and be preferable to carry out case, be not limited to the utility model, for
For those skilled in the art, the utility model can have various changes and change.It is all in new spiritual and former of this implementation
Within then, any modification, equivalent substitution and improvements made etc., it should be included within the scope of protection of the utility model.
