Description
Technical field
The utility model belongs to a kind of constant pressure arrangement, is specifically related to the diaphragm type constant pressure arrangement in heating system.
Background technology
The constant pressure arrangement usually needing installation reliable and stable in the heating system of station is changed in homogeneous solution-type reactor high/low temperature heating system, boiler room heat.
Constant pressure arrangement principle in heating system is based on ripple horse gas law, and ripple horse law refers to the perfect gas of certain mass, and when temperature-resistant, its pressure is inversely proportional to volume.
Above-mentioned said perfect gas refers to the gas strictly deferring to equation of gaseous state, and equation of gaseous state refers to PV=(m/M) RT=nRT.Just space gas is used as perfect gas when studying theorem.The interior energy that temperature-resistant gas molecule in other words has is constant, and molecule also wants the constancy of volume keeping gas certainly.So when we just can desperately exert oneself to push mutually again to study the intermolecular of its inside after gas volume compression, want the volume by keeping the mode of original distance to keep original, so pressure increases.Otherwise pressure reduces.So its pressure is inversely proportional to volume.Here it is ripple horse law.
Constant pressure arrangement equipment adopts system static pressure as the design initial pressure head in expansion tank, adopts the unvaporized pressure of hot water in guarantee system to move row terminal pressure head as in expansion tank.First start small pump during initial launch to water-filling in the hydroecium in system and air pressure tank, system is full of rear unnecessary water and is got in tank body.Because the Incoercibility of water, with the continuous increase of rate of water added, the volume of hydroecium also constantly expands and presses tank volume, and the pressure in tank also constantly raises.When pressure reaches design pressure, by pressure controller, small pump is closed.When intrasystem water expanded by heating makes system pressure increase to over design pressure, unnecessary water drains into water supply tank by safety valve and recycles, when the water in system because leakage or temperature decline and volume-diminished, when system pressure reduces, water in tank body is constantly pressed into the droop loss of pipe network replenishment system, when the minimum pressure that system pressure allows to design, make small pump restart moisturizing in pipe network and air pressure tank by pressure controller, so go round and begin again.
But existing constant pressure arrangement in use also also exists many defects.
Summary of the invention
The utility model proposes for solving prior art Problems existing, its objective is and provides the constant pressure arrangement of the diaphragm type in heating system.
The technical solution of the utility model is: the diaphragm type constant pressure arrangement in heating system, comprise vertical tank body, barrier film inner chamber being divided into hydroecium and air chamber is provided with in tank body, hydroecium is communicated with three-way pipe by flange, all the other two branch roads of three-way pipe are respectively arranged with No. I gate valve, blowoff valve, No. I described gate valve is communicated with circulation line, circulation line is communicated with multiple supply channel, supply channel is disposed with check-valves, No. II gate valve and be convenient to install the water pump flange of water pump, the nitrogen inject holes at the air chamber in tank body and tank body top, Pressure gauge installing hole is communicated with.
Seal is provided with in described nitrogen inject holes, Pressure gauge installing hole.
Also be provided with voltage-stablizer in described supply channel, voltage-stablizer is provided with electro connecting pressure gauge.
Described tank body is provided with leg.
Described leg is four or six.
Inner chamber is divided into hydroecium and air chamber by the tank body barrier film in the utility model, and hydroecium is communicated with circulation line, and circulation line is communicated with multiple supply channel, increase the stability supplied water, the voltage-stablizer that supply channel is arranged, electro connecting pressure gauge can use safely and effectively for a long time, and hydroecium is also connected with blowoff valve simultaneously, are convenient to safeguard, the utility model is not vaporized, not superpressure, can use after single aeration, good seal performance for a long time, carbonated drink does not contact, and avoids system oxidation to corrode.

Detailed description of the invention
Below, with reference to drawings and Examples, the utility model is described in detail:
As Fig. 1, shown in 2, diaphragm type constant pressure arrangement in heating system, comprise vertical tank body 1, be provided with in tank body 1 and inner chamber is divided into the barrier film of hydroecium and air chamber (not shown), hydroecium is communicated with three-way pipe by flange, all the other two branch roads of three-way pipe are respectively arranged with No. I gate valve 2, blowoff valve 3, No. I described gate valve 2 is communicated with circulation line 4, circulation line 4 is communicated with multiple supply channel 5, supply channel 5 is disposed with check-valves 6, No. II gate valve 7 and be convenient to install the water pump flange 8 of water pump, the nitrogen inject holes 9 at the air chamber in tank body 1 and tank body 1 top, Pressure gauge installing hole 10 is communicated with.
Seal is provided with in described nitrogen inject holes 9, Pressure gauge installing hole 10.Avoid the helium leak be filled in air chamber.
Also be provided with voltage-stablizer in described supply channel 5, voltage-stablizer is provided with electro connecting pressure gauge.
Be provided with barrier film in the middle part of the inner chamber of tank body 1, thus air chamber is formed at the top of tank body 1 inner chamber, hydroecium is formed at the bottom of tank body 1 inner chamber.
Described tank body 1 is provided with leg 11.Described leg 11 is four or six.
When heating system water temperature raises volumetric expansion, hot water progresses into the hydroecium of tank body 1, forces barrier film to be expanded, and hydroecium volume strengthens the volume of nitrogen in compression air chamber, and increases the pressure of air chamber.When heating system water temperature reduces, hydroecium volume shrinks, and the press water at this moment in tank body can the system of supplementing back automatically, makes heating system remain certain pressure.
Inner chamber is divided into hydroecium and air chamber by the tank body barrier film in the utility model, and hydroecium is communicated with circulation line, and circulation line is communicated with multiple supply channel, increase the stability supplied water, the voltage-stablizer that supply channel is arranged, electro connecting pressure gauge can use safely and effectively for a long time, and hydroecium is also connected with blowoff valve simultaneously, are convenient to safeguard, the utility model is not vaporized, not superpressure, can use after single aeration, good seal performance for a long time, carbonated drink does not contact, and avoids system oxidation to corrode.
