Abstract
The utility model discloses a pressurizing unit, and relates to the technical field of mechanical equipment. A check valve, a pressurizing pump, a butterfly valve and a flexible joint pipeline are sequentially connected; a pressurizing device is arranged at the high area water supply position; a pressure reducing and partitioning device comprises a filter, a pressure holding and releasing valve and a solenoid valve, the filter, the pressure holding and releasing valve and the solenoid valve are sequentially connected, and the pressure reducing and partitioning device is arranged at the high area water return position; bypasses are installed one side of the pressurizing device and one side of the pressure reducing and partitioning device and provided with plunger valves; a waterproof hammer is installed between the high area water supply position and high area water return position, and the pressurizing device and the pressure reducing and partitioning device are connected with a digital frequency converting control cabinet in a controlled mode. The pressurizing unit is used for a heat supply system with differential pressure, solves the problem of pressurization of a high area heat supply system and the problem that pressure in a low area is affected by overhigh water return pressure when heat exchange can not be carried out on low-temperature water, and can be automatically shut down according to the pressure of the low area, functions of the high area system and a low area system are partitioned after shut-down, and pressure of the high area system and the pressure of the low area system are independent of each other.
Description
Technical field
The utility model relates to a kind of supercharging unit, belongs to mechanical equipment technical field.
Background technology
In a lot of existing multilayers in living area (low layer), build a building and also have skyscraper building at present; when heating circulation water pressure of supply water does not reach high rise building water supply pressure; must configure heat supply supercharging unit; to meet the needs of high-rise heat supply; existing supercharging unit can not just be realized automatic shutdown function according to low district pressure in use; after shutdown, high sound zone system and low sound zone system can not be cut off, mutually can go here and there pressures, so use very inconvenient.
Summary of the invention
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of supercharging unit.
Supercharging unit of the present utility model, it is mainly by supercharging device, decompression partition device, water hammer-resistant device, digital frequency conversion switch board and bypass five parts form, described supercharging device comprises check-valves, booster pump, butterfly valve and hose adapter road, check-valves, booster pump, butterfly valve is connected successively with hose adapter road, supercharging device is arranged on high district watering place, described decompression partition device comprises filter, hold and press relief valve and magnetic valve, filter, hold and press relief valve to be connected successively with magnetic valve, decompression partition device is arranged on backwater place, high district, and a side of supercharging device and a side of decompression partition device are all provided with bypass, plunger valve is installed in bypass, between the water supply of Qie Gao district and backwater, water hammer-resistant device is installed, supercharging device, decompression partition device all with digital frequency conversion switch board control connection.
As preferably, described magnetic valve is normally closed solenoid valve, and unit is valve open when normal operation, guarantee the normal circulation for backwater, when unit is out of service, solenoid closure cuts off primary water and secondary backwater, is divided into two autonomous systems that pressure is different.
As preferably, described holding presses relief valve not only to have the dynamic pressure of subtracting but also subtract static pressure function, and the identical pressure of Ba Gao district pressure of return water decompression Wei Yudi district pressure of return water, guarantees that both are independent of each other, thereby guarantees that the heating power causing because pressure is different is unbalance.
As preferably, described bypass is comprised of plunger valve and pipe fitting, and plunger valve is normal closing, and when a pressure of supply water meets system pressure requirement, can close unit, opens supercharging partition and decompression partition place bypass, and system is normally moved, and reaches energy-saving effect.
The beneficial effects of the utility model: it can overcome the drawback of prior art; reasonable in design is novel; for there is the heating system of pressure reduction; solved when water at low temperature cannot heat exchange; the problem of the supercharging problem of high district heating system and the low district of the too high impact of pressure of return water pressure; unit can just be realized automatic shutdown function according to low district pressure, after shutdown, by high sound zone system and low sound zone system cutting function, does not go here and there mutually pressure.
Accompanying drawing explanation
For ease of explanation, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, this specific embodiment is by the following technical solutions: it is mainly by supercharging device 1, decompression partition device 2, water hammer-resistant device 3, digital frequency conversion switch board 4 and bypass 5 five parts form, described supercharging device 1 comprises check-valves 1-2, booster pump 1-3, butterfly valve 1-4 and hose adapter road 1-5, check-valves 1-2, booster pump 1-3, butterfly valve 1-4 is connected successively with hose adapter road 1-5, supercharging device 1 is arranged on high district watering place, described decompression partition device 2 comprises filter 2-1, hold and press relief valve 2-2 and magnetic valve 2-3, filter 2-1, hold and press relief valve 2-2 to be connected successively with magnetic valve 2-3, decompression partition device 2 is arranged on backwater place, high district, and a side of supercharging device 1 and a side of decompression partition device 2 are all provided with bypass 5, plunger valve 5-1 is installed in bypass 5, between the water supply of Qie Gao district and backwater, water hammer-resistant device 3 is installed, supercharging device 1, decompression partition device 2 all with digital frequency conversion switch board 4 control connections.
Wherein, described magnetic valve 2-3 is normally closed solenoid valve, and unit is valve open when normal operation, guarantee the normal circulation for backwater, when unit is out of service, magnetic valve 2-3 is closed cuts off primary water and secondary backwater, is divided into two autonomous systems that pressure is different; Described holding presses relief valve 2-2 not only to have the dynamic pressure of subtracting but also subtract static pressure function, and the identical pressure of Ba Gao district pressure of return water decompression Wei Yudi district pressure of return water, guarantees that both are independent of each other, thereby guarantees that the heating power causing because pressure is different is unbalance; Described bypass 5 is comprised of plunger valve 5-1 and pipe fitting, and plunger valve 5-1 is normal closing, and when a pressure of supply water meets system pressure requirement, can close unit, opens supercharging partition and decompression partition place bypass, and system is normally moved, and reaches energy-saving effect.
