Abstract
The utility model discloses a vacuum water diversion box for a water pump without a bottom valve. The vacuum water diversion box includes a vacuum water tank. The water feeding end of the vacuum water tank is in airtight connection with a suction pipe used for sucking water from a water sump. The water discharging end of the vacuum water tank is in airtight connection with the water pump. In addition, the top of the vacuum water tank is provided with a water supplementation opening and an exhaust opening, and the bottom of the vacuum water tank is provided with a sewage discharging opening. The water supplementation opening is connected with a water supplementation pipeline through a water supplementation valve. The sewage discharging opening is connected with a sewage discharging pipeline through a sewage discharging valve. The exhaust opening is connected with exhaust equipment through an exhaust valve. Electric associated valve automatic control can be adopted for the water supplementation valve, the exhaust valve and the sewage discharging valve. Water supplementation and sewage discharging of the vacuum water diversion box for the water pump without the bottom valve can be achieved, and regular automatic sewage discharging and water supplementation can be further achieved.
Description
Technical field
The utility model relates to a kind of water pump without bottom valve vacuum water diversion case.
Background technique
The water inlet pipe mouth end overwhelming majority of existing water pump has all been used bottom valve device, and the resistance of this bottom valve device accounts for the more than 70% of water pump suction pipe resistance, has not only increased power consumption, and has reduced suction lift.This water pump generally adopts the pump form that opens of artificial diversion in addition, and operation is very inconvenient.
At present, occurred on the market a kind of water pump without bottom valve, this water pump without bottom valve is to utilize vacuum water diversion case to hoard quantitative water, and then, in starting mode of pump process, vacuum water diversion box-shaped becomes negative pressure, thereby forms continuous drainage under atmospheric effect.So not only substitute the starting mode of bottom valve of water pump and artificial diversion, and can greatly simplify starting mode of pump programmed sequence of operations, reduced staff's labor intensity.
But existing water pump without bottom valve does not have moisturizing and pollution discharge mechanism with vacuum water diversion case, thereby use after a period of time, all need to tear machine blowdown, moisturizing open, use inconvenience.
Model utility content
Technical problem to be solved in the utility model is, for prior art deficiency, to provide the water pump without bottom valve vacuum water diversion case of the regular moisturizing blowdown of a kind of energy.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of water pump without bottom valve vacuum water diversion case, it comprises a vacuum water tank, the airtight connection of feed-water end of this vacuum water tank is for the suction sleeve from sump water suction, the airtight connection water pump of discharge ends of vacuum water tank, and the feed-water end of this vacuum water tank is arranged at the top of this vacuum water tank, the top of this vacuum water tank separately arranges water supplement port and relief opening, the bottom of this vacuum water tank is made as taper, this taper bottom sewage draining exit is set bottom; This water supplement port is connected with moisturizing pipeline through water-feeding valve, and this sewage draining exit is connected with blow-off line through blowdown valve, and this relief opening is connected with gas outlet means through outlet valve, and this water-feeding valve and blowdown valve adopt electronic associated valve automatically to control.。
Further being improved to of such scheme, this vacuum water tank can be selected steel plate thickness according to water tank size, preferably adopts 6mm hot rolling steel plate to make.
Vacuum water tank of the present utility model top arranges water supplement port, and and then through water-feeding valve, connect moisturizing pipeline; The bottom of vacuum water tank arranges sewage draining exit, and connects blow-off line by blowdown valve, so just can realize vacuum water tank is carried out to moisturizing, blowdown, if adopt electronic associated valve to control, also can realize automatic water supplement blowdown.

Embodiment
As shown in Figure 1, the utility model water pump without bottom valve comprises a vacuum water tank 1 by vacuum water diversion case one embodiment, the airtight connection of feed-water end of this vacuum water tank 1 is for the suction sleeve 2 from sump water suction, the airtight connection water pump 3 of discharge ends of vacuum water tank 1, and the top of this vacuum water tank 1 arranges water supplement port 4 and relief opening 9, and bottom arranges sewage draining exit 5.This water supplement port 4 can be connected to facilitate to vacuum water tank 1 moisturizing through water-feeding valve 6 and moisturizing pipeline; This sewage draining exit 5 is connected with blow-off line through blowdown valve 7, for vacuum water tank provides dirt eliminating function; This relief opening 9 can be connected that with gas outlet means the air in vacuum water tank 1 is drained through outlet valve 8.Further, as shown in Figure 2, this water-feeding valve 6, outlet valve 8 and blowdown valve 7 adopt electronic associated valve automatically to control, thereby can realize the regular automatic pollution discharge of vacuum water tank, moisturizing, exhaust.The making of this vacuum water tank 1 adopts 6mm hot rolling steel plate, must guarantee its seal with the joint of suction sleeve 2 and water pump 2.
Claims (2)
1. a water pump without bottom valve vacuum water diversion case, comprise a vacuum water tank, the airtight connection of feed-water end of this vacuum water tank is for the suction sleeve from sump water suction, the airtight connection water pump of discharge ends of vacuum water tank, it is characterized in that, the feed-water end of this vacuum water tank is arranged at the top of this vacuum water tank, and the top of this vacuum water tank arranges water supplement port and relief opening, the bottom of this vacuum water tank is made as taper, this taper bottom sewage draining exit is set bottom; This water supplement port is connected with moisturizing pipeline through water-feeding valve, and this sewage draining exit is connected with blow-off line through blowdown valve, and this relief opening is connected with gas outlet means through outlet valve, and this water-feeding valve, outlet valve and blowdown valve adopt electronic associated valve automatically to control.
2. water pump without bottom valve according to claim 1 vacuum water diversion case, is characterized in that, this vacuum water tank adopts 6mm hot rolling steel plate to make.
