Abstract
The utility model relates to a kind of reserve pump anti-freezing structure, comprise main pump and stand by pump, main pump and stand by pump parallel join, between main pump and outlet valve, be provided with main pump check valve, between stand by pump and outlet valve, be provided with stand by pump check valve, main pump check valve and stand by pump check valve side are equipped with the little valve of a bypass.The utility model is respectively set up a little valve of bypass at main pump check valve and stand by pump check valve side on existing equipment basis, the little valve of the bypass of crack stand by pump check valve in the time that main pump moves, the water of outfall sewer flows backwards through the outlet valve of stand by pump, through the little valve of bypass of check valve side, the flow through inlet valve of reserve pump and reserve pump, flow back to main pump inlet pipe, making has water flow, unlikely icing frozen block in standby pump.The mouth of pipe of the little valve turnover of the bypass of check valve is simultaneously pressed close to check valve, and recirculation water conducts heat also can effectively prevent that check valve from freezing, thereby has thoroughly solved the antifreeze problem of reserve pump.
Description
Technical field
The utility model relates to a kind of water pump linkage structure, is specially a kind of anti-freezing structure that can prevent in the winter time icing frozen block in reserve pump.
Background technique
Along with the fast development of domestic industry and the fast lifting of automatic control level, various devices require also more and more higher to the operation stability degree of system, many key equipments that easily break down are all provided with the standby equipment the same with the equipment of online use, in the time that online equipment breaks down not competent work, standby equipment starts immediately by the process parameter instruction of instrument transmission, take over the online equipment work of breaking down, do not cause whole device or whole production system out of service because of the fault of individual equipment.
As shown in Figure 1, the water pump of industrial on-line operation generally includes main pump and stand by pump, and the inlet valve of main pump and stand by pump and outlet valve all often leave under normal circumstances, by flowing of water in check valve restriction stand by pump is set.In the time that the main pump of on-line operation breaks down not competent work, stand by pump starts immediately by the process parameter instruction of instrument transmission, takes over the online equipment work of breaking down, and main pump and stand by pump can be used alternatingly.But having water in the control pump of check valve due to stand by pump outlet at north of china in winter is immobilising, if winter reserve pump without freezing in antifreezing measure pump, frozen block, even freezing unavoidable, cannot realize standby functions.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of can effectively prevent reserve pump frozen block and freezing anti-freezing structure in the winter time.
For addressing the above problem, the utility model provides a kind of reserve pump anti-freezing structure, comprise main pump and stand by pump, main pump and stand by pump parallel join, between described main pump and outlet valve, be provided with main pump check valve, between stand by pump and outlet valve, be provided with stand by pump check valve, described main pump check valve and stand by pump check valve side are equipped with the little valve of a bypass.
The beneficial effects of the utility model are: the utility model is respectively set up a little valve of bypass at main pump check valve and stand by pump check valve side on existing equipment basis, the little valve of the bypass of crack stand by pump check valve in the time that main pump moves, the water of outfall sewer flows backwards through the outlet valve of stand by pump, through the little valve of bypass of check valve side, the flow through inlet valve of reserve pump and reserve pump, flow back to main pump inlet pipe, making has water flow, unlikely icing frozen block in standby pump.The mouth of pipe of the little valve turnover of the bypass of check valve is simultaneously pressed close to check valve, and recirculation water conducts heat also can effectively prevent that check valve from freezing, thereby has thoroughly solved the antifreeze problem of reserve pump.
Brief description of the drawings
Be described in further detail with regard to the specific embodiment of the present invention below in conjunction with accompanying drawing, wherein:
Fig. 1 is existing water pump linkage structure schematic diagram;
Fig. 2 is linkage structure schematic diagram of the present utility model;
In figure: 1-main pump, 2-stand by pump, 3-water intake, 4-water outlet, 5-inlet valve, 6-outlet valve, 7-main pump check valve, 8-stand by pump check valve, the little valve of 9-stand by pump bypass, the little valve of 10-main pump bypass.
Embodiment
Shown in Fig. 2, the utility model is a kind of reserve pump anti-freezing structure, comprise main pump 1 and stand by pump 2, main pump 1 and stand by pump 2 parallel joins, between main pump 1 and outlet valve, be provided with main pump check valve 7, between stand by pump 2 and outlet valve, be provided with stand by pump check valve 8, described main pump check valve 7 sides are provided with the little valve 10 of main pump bypass, and stand by pump check valve 8 sides are provided with the little valve 9 of stand by pump bypass.
When use in winter main pump 1 moves, close the little valve 10 of main pump bypass of main pump 1, open the little valve 9 of stand by pump bypass of stand by pump 2, guarantee that the water yield that the little valve 9 of bypass passes through can be antifreeze, the unlikely stand by pump 2 that makes reverses, in the time that main pump 1 breaks down, while operation stand by pump 2 as main pump, the little valve of this stand by pump bypass cuts out.It is to be used that main pump 1 fault can be used as stand by pump etc. after getting rid of, and in like manner can open the little valve 10 of main pump bypass and control the water yield and carry out antifreeze.Two water pumps can be used alternatingly, and coordinate bypass little valve to realize winter water pump antifreeze.
The above; only for the better embodiment of the present invention, but protection domain of the present invention is not limited to this, is anyly familiar with in technical scope that those skilled in the art disclose in the present invention; the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore protection domain of the present invention is as the criterion with the protection domain of claims.
Claims (1)
1. a reserve pump anti-freezing structure, comprise main pump and stand by pump, main pump and stand by pump parallel join, between described main pump and outlet valve, be provided with main pump check valve, between stand by pump and outlet valve, be provided with stand by pump check valve, it is characterized in that described main pump check valve and stand by pump check valve side are equipped with the little valve of a bypass.
