Abstract
The utility model belongs to the technical field of pipe connectors, and particularly relates to a water inflow/outflow connector for a water pump. A second hollow cylinder is arranged at one end of a first hollow cylinder, the first hollow cylinder and the second hollow cylinder are arranged on the coaxial line, the outer diameter of the first hollow cylinder is larger than that of the second hollow cylinder, the inner diameter of the first hollow cylinder is larger than that of the second hollow cylinder, and inner holes of the first hollow cylinder and inner holes of the second hollow cylinder form a water inflow channel or a water outflow channel. A plurality of protruding rings are arranged at the outer end of the outer cylindrical surface of the second hollow cylinder axially. The water inflow/outflow connector is simple in structure, low in cost, and suitable for being used on various water pumps. Meanwhile, according to the water inflow/outflow connector, pipe diameters are reduced, pressure is increased, pump head is increased, use cost is reduced, and generality of the water pump is improved.
Description
Technical field:
The utility model belongs to the pipe joint technical field, refers in particular to a kind of for advancing on water pump/water output connector.
Background technique:
The water inlet interface of water pump and water outlet mouthpiece are generally the calibers of fixing.Fixing caliber can only intrinsic lift.In the situation that the different lifts of needs just need to use the water pump of different calibers.Such situation has just increased user cost.
Summary of the invention:
The purpose of this utility model be to provide a kind of simple in structure, cost is low, dwindle caliber increases the advancing/water output connector on water pump that be used for that pressure improves pump head.
The utility model is achieved in that
Be used for advancing/water output connector on water pump, an end at the first hollow circular cylinder is provided with the second hollow circular cylinder, the first hollow circular cylinder and the second hollow circular cylinder are coaxially set, the external diameter of the first hollow circular cylinder is greater than the external diameter of the second hollow circular cylinder, the internal diameter of the first hollow circular cylinder is greater than the internal diameter of the second hollow circular cylinder, the endoporus of the endoporus of the first hollow circular cylinder and the second hollow circular cylinder forms intake tunnel or exhalant canal, axially is provided with several bulge loops in the outer end of the external cylindrical surface of the second hollow circular cylinder.
Be provided with the circular cone of hollow between the first above-mentioned hollow circular cylinder and the second hollow circular cylinder, the bigger diameter end of circular cone is connected with an end of the first hollow circular cylinder, miner diameter end is connected with one of the second hollow circular cylinder, the large footpath of the outside of the circular cone of hollow is identical with the external diameter of first end hollow circular cylinder, the external diameter of path and the second hollow circular cylinder is identical, and inner large footpath is identical with the internal diameter of the first hollow circular cylinder, the internal diameter of path and the second hollow circular cylinder is identical.
It is trapezoidal that above-mentioned bulge loop is that the cross section is, the detent projection that bigger diameter end forms towards the first hollow circular cylinder.
Be provided with the convex annular edge away from an end of the second hollow circular cylinder on the first above-mentioned hollow circular cylinder.
The advantage that the utility model is given prominence to compared to existing technology is:
The utility model structure is simple, cost is low, dwindle caliber increases pressure raising pump head, reduces user cost, has improved the versatility of water pump, is applicable on various water pumps.
