The utility model provides a protection water pump impeller's pipeline connection structure, its impeller of effective protection water pump, increase of service life.
Description
Technical Field
The utility model relates to a protection water pump impeller's pipeline connection structure belongs to water supply equipment technical field.
Background
Be provided with booster water pump on water supply pipe of water factory, the water pressure of supplying water is not enough to supply water through opening booster water pump increase water pressure when its purpose appears the unexpected condition, prevent to appear the condition of cutting off the water supply inadequately because of water pressure, because of being prepared for the unexpected condition, booster water pump all is in idle state under the most majority of time, but water of water supply pipe is continuously supplied with, booster water pump's impeller still continuously receives the impact of rivers, cause the wearing and tearing of impeller, reduce short life, the impeller is the core part of water pump, it is expensive increase cost expenditure not only to change the impeller, it causes inconvenience for the user to still need cut off the water during change.
Disclosure of Invention
The utility model aims to solve the technical problem that a pipeline connection structure of protection water pump impeller is provided, its impeller of effective protection water pump, increase of service life also need not the water-break and causes inconvenience to the user when the impeller is changed, can solve the not enough of prior art.
The technical scheme of the utility model is that: the utility model provides a pipeline connection structure of protection water pump impeller, is including the delivery pipe that is provided with booster water pump, set up on the delivery pipe and be connected with the side pipe, the delivery pipe is equipped with first valve, the side pipe does not is equipped with the second valve, first valve is located booster water pump top, and the end of intaking of side pipe is connected in first valve top, and the play water end is connected in booster water pump below. The second valve is closed when needing pressure boost water supply, opens first valve, opens booster water pump and supplies water through the delivery pipe, and under the condition that need not supply water, first valve is closed, and the second valve is opened, supplies water and does not pass through booster water pump and carry through the side pipe, can not cause the impact to booster water pump's impeller, increase of service life, simultaneously the impeller change only need from the side pipe supply water can, need not cut off the water supply cause inconvenience to the user.
And a filter is arranged at a water supply pipe between the booster water pump and the first valve. The filter filters stone particles and the like in water, reduces the damage of the stone particles and the like to the booster water pump impeller, and has a better protection effect on the impeller.
The filter comprises a shell, a shell cover and a filtering device, wherein an opening is formed in the top of the shell, the filtering device is detachably arranged in the shell, and the shell cover is arranged at the opening of the shell and is in sealing connection with the shell. Because of the filtration impurity in the filter equipment needs clear up, only need open the cap on shell top, to filter equipment dismantle clear up or change can, need not to pull down whole filter equipment, convenient clearance.
Further filter equipment is the cartridge filter, is provided with the support on the cartridge filter, and the cartridge filter passes through support mounting in the casing, and support, cap, casing bottom are equipped with corresponding screw, and the screw passes cap, support and is connected bottom the casing, is provided with sealed the pad between the screw of screw and cap. When fixing the cap through the screw, also fix the cartridge filter simultaneously, convenient dismantlement and installation.
Further, the filter cartridge is in a shape of a circular truncated cone which is transversely placed, and the inlet end is smaller than the outlet end. The impurities filtered are accumulated at the bottom of the filter cylinder, and the reflux of the impurities is reduced.
Further the filter cartridge is made of 304 steel. The water body is not polluted by rusting, and the use is safer and more sanitary.
To sum up, the utility model provides a protection water pump impeller's pipeline connection structure, its impeller of effective protection water pump, increase of service life.
