Embodiment
With reference to the drawings and specific embodiments, the utility model is described in further detail.It should be understood that these embodiments are only used for
Illustrate the utility model rather than limit scope of the present utility model.In addition, it is to be understood that reading the utility model instruction
Content after, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values equally fall
In scope defined herein.
As shown in Figure 1, intake antrum 3 is respectively equipped with a kind of new blocking pressure regulator, including cylinder, the cylinder up and down
With water chamber 6, connected between the intake antrum 3 and water chamber 6 by pressure-reduction outlet 11, pressure-reduction outlet 11 can be made by being provided with intake antrum 3
The valve piston 8 of closing, the intake antrum 3 connects water inlet 7, the water chamber 6 connect be provided with below delivery port 4, cylinder with
Big piston 10 is provided with the big plunger shaft that high-pressure water 5 is connected, big plunger shaft, connecting rod 9 is passed through between big piston 10 and valve piston 8
Connection, the top of valve piston 8 is connected with spring 13, and valve piston 8 can close pressure-reduction outlet 11 in the case where spring 13 holds out against effect, small
The compressible spring 13 in the case where big piston 10 holds out against effect of piston 8 opens pressure-reduction outlet 11.
Blocking pressure regulator of the present utility model is tubular, and intake antrum 3 is high area's backwater cavity, and water chamber 6 is relief chamber,
Connection high-pressure water 5 in big plunger shaft, the other end of high-pressure water 5 is connected with pipe network check-valves, water pump.By this blocking pressure regulator
It is arranged on high area's return piping, during system operation, heating hot water is delivered to driving adjuster and high area's radiator by water pump successively
Heating, high-pressure water 5 promotes big piston 10 up, due to big piston 10 by driving adjuster to enter big plunger shaft cavity of resorption
Thrust is more than the resistance of the upper springs 13 of valve piston 8, therefore the supply water big piston 10 of promotion, connecting rod 9 and valve piston 8 are up, small
It is about to pressure-reduction outlet 11 on piston 8 to open, now the backwater of high area's radiator enters intake antrum 3 from water inlet 7, and passes through pressure-reduction outlet
11 flow into water chamber 6, flow into low area's return water system finally by delivery port 4, the dynamic pressure of Shi Gao areas backwater lowers；When being
When system is stopped, the pressure of high-pressure water 5 will be zero, the thrust of big piston 10 is disappeared, in the presence of spring 13, small work
Fill in 8 descending, pressure-reduction outlet 11 is closed, together kept apart high sound zone system and low sound zone system with system check valve, so that high area
System and low sound zone system static pressure cut-off.
In order in time outside the gas discharge system in system, be provided with above the cylinder for blocking pressure regulator exhaust outlet 2,
Lower section is provided with passage 12, wherein passage 12 also can water flowing, exhaust outlet 2 is connected with air, and pressure regulation is blocked when backwater enters
After device, flow velocity reduction, gas separates, and gas rises, through the discharge system of exhaust outlet 2 outside, the gas above big piston 10 leads to
Cross passage 12 and enter relief chamber i.e. water chamber 6, be discharged to by the space between valve piston 8 and connecting rod 9 in intake antrum 3,
It is discharged to by exhaust outlet 2 outside system.
Because the height and high area's construction area of every building are differed, the pressure to be subtracted also is differed, and this practicality is new
Type is blocking the top of pressure regulator to be provided with hand-operated pressure regulation appliance 1, and guide rod is passed through between hand-operated pressure regulation appliance 1 and valve piston 8
Connected with the spring 13 being arranged on the guide bar.Hand-operated pressure regulation appliance 1 can be arranged on cylinder by the way of handwheel and threaded connection
On body, when rotation hand wheel, handwheel lifting changes the decrement of spring 13, and 1 need of handwheel regulator can realize regulation bullet
The elastic force of spring 13.According to the height of building, the elastic force of spring 13 is adjusted by hand-operated pressure regulation appliance 1, pressure-reduction outlet is determined
The pressure and flow of backwater needed for the size of pressure is jumped out at 11.
The utility model will be depressurized, blocked, exhaust is integrated, and by hydraulic automatism control, reduce equipment, and this
Block pressure regulator simple in construction, itself waterpower completion work is fully utilized so that the reliability of whole system is greatly improved.
