Description
Technical field
The realization decompression that the present invention relates to use in fluid circulation system and the device of auto-switch function are such as in the heating system central air conditioning water system or the realization decompression of using in the hot water service and the device of auto-switch function.
Background technique
Direct connection heating system for high-rise building is a kind of heating system of a kind of Xiang Gao district radiator heating, backwater and low district networking, this system problem to be solved be must Jiang Gao district heating system dynamic pressure and static pressure lower, puncture in case high district heating system pressure will hang down district's radiator.Therefore this system mainly is made up of booster pump and control system, reduction valve, solenoid valve and safety check etc., and booster pump and control system thereof are used for the heating heating agent is sent into high district radiator.When system stopped, closed electromagnetic valve with safety check, was closed high sound zone system, and high sound zone system and low sound zone system are separated, and prevented that the static pressure of high sound zone system is passed to low district.The dynamic pressure that reduction valve is used for Jiang Gao district heating water return lowers.The problem that this system exists is: at first, can turn-off, also will establish solenoid valve in the practicality, promptly still finish by reduction valve and solenoid valve though the reduction valve that has is known as, like this equipment the more, reliability is poorer, rate of fault heals greatly; Secondly, solenoid valve always is in charged working state when opening, and long chargedly influences its life-span, especially for heating system, because the too high radiating effect of temperature is bad more like this; At last, reduction valve complex structure, making bother, cost an arm and a leg, particularly spring, rubber are used in many places, the phenomenon of metal fatigue, ageing of rubber can appear in long-time use unavoidably, particularly water flow section is long-time contacts with rubber and wearing and tearing, cause rubber deformation, parameter change, problems such as system's operation fluctuation even system overpressure occur.Above-mentioned all problems will cause the poor reliability of system.
Summary of the invention
At the deficiencies in the prior art, the object of the present invention is to provide a kind of block device that can avoid above-mentioned deficiency.
The object of the present invention is achieved like this: block device is a jar shape, on jar intake pipe and water outlet are arranged, the bottom of intake pipe is provided with pressure-reduction outlet, the upper end of connecting rod is small piston fixedly, and the lower end of connecting rod is big piston fixedly, and small piston is in the water inlet tube chamber, flap for pressure-reduction outlet, big piston is arranged in the big piston chamber, and the high drive water pipe is arranged at bottom, big piston chamber, and the other end of this water pipe is communicated with system safety check front tube.On height district return piping, block device is set, when system moves, booster pump will supply water (heating agent) deliver to high drive water pipe He Gao district's radiator heat release successively, water supply enters the big piston chamber by the high drive water pipe, because the pressure that big piston bore is greater than small piston, therefore supplying water, it is up to promote big piston, connecting rod and small piston, pressure-reduction outlet is opened, at this moment, high district radiator backwater enters block device, by pressure-reduction outlet, jar chamber and water outlet, make the dynamic pressure of high district backwater subtract successively, flow into low district return water system; When system's termination of pumping, the high drive siphon pressure reduces, the pressure difference that makes the big piston two sides be zero (because of between connecting rod and the axle sleeve, gapped between big piston and its chamber wall), small piston is descending under the effect of height district backwater, pressure-reduction outlet is closed, high sound zone system and low sound zone system are separated, thus the partition of assurance high low area system static pressure.
The present invention compares with the prior art scheme, and it has reduced equipment for system, and itself has utilized the pressure difference of system's safety check front end, big or small piston area product moment to become power, drive small piston, automatically realize switch and decompression, it is simple in structure, and the reliability of system is also improved greatly.
Description of drawings
Further specify the present invention below in conjunction with accompanying drawing.
Fig. 1 is a system of the present invention connection diagram.
Fig. 2 is the structural representation of block device.
Embodiment
Referring to Fig. 1, direct connection heating system for high-rise building has booster pump 1 and control system thereof, safety check 3 He Gao district radiators 6, on height district return piping 7 block device 4 is set.Booster pump and control system thereof are used for the heating heating agent is sent into high district radiator.The 8th, low district radiator.
Referring to Fig. 2, block device is a jar shape, on jar intake pipe 9 and water outlet 16 are arranged, the bottom of intake pipe is provided with pressure-reduction outlet 21, the upper end of connecting rod 23 is small piston 22 fixedly, the lower end of connecting rod is big piston 17 fixedly, small piston is in the water inlet tube chamber, be the flap of pressure-reduction outlet, big piston is arranged in the big piston chamber 15, and bottom, big piston chamber is communicated with high drive water pipe 2, the other end of this water pipe is communicated with system safety check 3 front tube, for small piston is closed more reliably, water hole 14 is set on the big piston chamber, be communicated with the jar chamber.When system moves, booster pump will supply water (heating agent) deliver to high drive water pipe He Gao district's radiator heat release successively, water supply enters the big piston chamber by the high drive water pipe, and the pressure that big piston bore is greater than small piston, and supplying water, it is up to promote big piston, connecting rod and small piston, pressure-reduction outlet is opened, at this moment, high district radiator backwater enters block device, successively by pressure-reduction outlet, jar chamber and water outlet, the pressure of Jiang Gao district backwater lowers, and flows in the low district return piping; When system's termination of pumping, the high drive siphon pressure reduces, and the pressure difference that makes the big piston two sides is zero, small piston is descending under the effect of height district backwater, pressure-reduction outlet is closed, high sound zone system and low sound zone system are separated with safety check 3, thus the partition of assurance high low area system static pressure.
With outside the intrasystem gas discharge system, on block device tank body top relief opening 10 is set in time, this relief opening is connected with outlet valve 5.Enter the jar chamber of block device when backwater after, flow velocity reduces, and the gas in the backwater is separated, and gas rises and discharges through relief opening to outlet valve 5.
Since the height district area of every building with highly be not quite similar, the pressure size that subtracts is also inequality, be provided with hand-operated pressure regulation appliance: pressure regulating cavity 18 is set below pressure-reduction outlet for this reason, the chamber wall in this chamber is two-layer, and two-layer chamber wall all is with water hole 19,13, and wherein the inner layer cavity wall is fixed, outer chamber wall 12 is rotary, the top of outer chamber wall is fixed on the gearwheel 11, large and small gear engagement, and small gear 24 live axles 25 are arranged on the outside of block device.High district backwater flows into a jar chamber through the water hole of pressure regulating cavity chamber wall again behind pressure-reduction outlet, the corresponding area in wall water hole, two-layer chamber is big more, and the water yield of outflow is many more, otherwise the water yield that flows out is few more.When needing to regulate, the manual drives axle, small gear, gearwheel rotate successively, drive outer chamber wall, regulate backwater discharge and pressure.
To sum up the present invention integrates the current limliting step-down, gentle water separation function is turn-offed in termination of pumping, and reliability improves greatly.
