Drawings
The invention will be further described with reference to the drawings and embodiments.
FIG. 1 is a front view of the present invention;
fig. 2 is a cross-sectional view of the present invention.
Detailed Description
The water pump seat with switchable bidirectional flow channels as described in fig. 1 and 2 comprises a body 1 of the water pump seat made of metal or engineering plastic. The body 1 is provided with a water inlet 2, a first water outlet 3, a second water outlet 4 and a switching runner 5. The first water outlet 3 is communicated with the switching flow passage 5 through the first water outlet channel 31, the second water outlet 4 is communicated with the switching flow passage 5 through the second water outlet channel 41, and the switching flow passage 5 is communicated with the water inlet 2 through the impeller cavity. A switching valve device is also provided in the switching flow passage 5. When the water pump works, the impeller rotates to pump water into the impeller cavity from the water inlet 2, and then the water selectively enters the first water outlet channel 31 or the second water outlet channel 41 under the action of the switching valve device, so that the effect of switching to different heat exchange systems is achieved.
The switching valve device may be operated by external force such as mechanical power, or may be hydraulically pushed by forward rotation or reverse rotation of the water pump to perform switching.
Further preferably, the above-described switching valve device includes a valve ball 6. The valve ball 6 is provided in the switching flow path 5 and is movable (rolling) in the switching flow path 5 so that the first water outlet passage 31 can be blocked when the valve ball 6 moves to the first water outlet passage 31 side and the second water outlet passage 41 can be blocked when the valve ball 6 moves to the second water outlet passage 41 side.
Further preferably, the interface between the switching flow channel 5 and the first water outlet channel 31 is provided with a first sealing structure, the interface between the switching flow channel 5 and the second water outlet channel 41 is provided with a second sealing structure, and both the first sealing structure and the second sealing structure can be sealed by the valve ball 6, so that the effect of sealing the two water outlet channels by the valve ball 6 is enhanced, and water leakage and water seepage are avoided.
Further preferably, the first water outlet channel 31, the second water outlet channel 41 and the switching flow channel 5 are arranged coaxially, and are all arranged horizontally as shown in fig. 2; in the water pump installation process, the placement of the water pump seat also enables the first water outlet channel 31, the second water outlet channel 41 and the switching flow channel 5 to be horizontally arranged. Therefore, the movement direction of the valve ball 6 in the switching flow passage 5 is in a vertical relation with the direction of gravity borne by the valve ball 6, and the movement of the valve ball 6 is not driven by gravity, so that the control is more accurate.
Further preferably, the first closure structure is an annular gasket 33. The sealing gasket 33 is connected and installed at the end part of the first water outlet channel 31, and the inner diameter of the sealing gasket 33 is smaller than the outer diameter of the valve ball 6, so that the sealing gasket can be bonded and sealed with the outer surface of the valve ball 6, and the bonded and sealed part forms a sealing surface for sealing the first water outlet channel 31. The second closure structure is also an annular gasket 43. The sealing gasket is connected and installed at the end part of the second water outlet channel 41, and the inner diameter of the sealing gasket is smaller than the outer diameter of the valve ball 6, so that the sealing gasket can be bonded and sealed with the outer surface of the valve ball 6, and the bonded and sealed part forms a sealing surface for sealing the second water outlet channel 41.
It is further preferred that the impeller chamber and the switching flow passage 5 communicate with each other through a first communication passage 32 and a second communication passage 42, and that the first communication passage 32 and the second communication passage 42 are separated from each other. The first communication channel 32 is adjacent to the first water outlet channel 31, the second communication channel 42 is adjacent to the second water outlet channel 41, and the outlet of the first communication channel 32 is located between the inlet of the first water outlet channel 31 and the outlet of the second communication channel 42.
In this way, the preset main rotation direction of the water pump is clockwise, the first water outlet 3 is a main water outlet, when the water pump runs clockwise, water flows into the impeller cavity through the water inlet 2, and under the condition that the impeller works, the water enters the switching flow passage 5 through the first communication passage 32 and the second communication passage 42; because the water pump runs clockwise and is synchronous with the first communication channel 32, the water pressure entering the switching channel 5 through the first communication channel 32 is larger than that of the second communication channel 42, the valve ball 6 is extruded by the water pressure to move towards the second water outlet channel 41 and is stopped at the sealing gasket 43 to form a seal, and the water is pumped out from the first water outlet 3.
On the contrary, when the impeller rotates clockwise, the impeller and the second communication channel 42 form synchronization, so that the water pressure entering the switching flow channel 5 through the second communication channel 42 is larger than that of the first communication channel 32, the valve ball 6 is extruded by the water pressure to move towards the first water outlet channel 31 and is stopped at the sealing gasket 33 to form a seal, and the water is pumped out from the second water outlet 4.
Through the hydraulic driving mode of the impeller with different steering, the water is pumped to the two water outlets, the space of the water pump is greatly saved, the mounting volume of the water pump is minimized, and the mounting and maintenance cost is reduced.
Further preferably, a retaining structure is also provided within the body 1. In a state where the second water outlet 4 does not discharge water, the holding structure can directly or indirectly act on the valve ball 6, so that the valve ball 6 blocks the second water outlet channel 41. The above-mentioned second water outlet 4 does not discharge water includes two cases, one is that the first water outlet 3 discharges water, and the other is that the water pump stops running.
It is further preferred that the holding structure comprises an expansion chamber 7 of variable volume arranged inside the body 1. The expansion chamber 7 is led to the first water outlet channel 31 through an expansion waterway 72 which is also positioned in the body 1, and a pressure chamber 8 which is abutted with the outer wall of the expansion part of the expansion chamber 7 is arranged in the body 1. The pressure chamber 8 is pre-set with a suitable pressure, such as a pre-filled gas, and the gas does not leak from the pressure chamber 8.
During the clockwise rotation of the impeller, part of water enters the expansion cavity 7 through the expansion waterway 72, is extruded by the water entering the expansion cavity 7, and the expansion cavity 7 expands and deforms towards the pressure cavity 8; when the water pump stops running, the pressure cavity 8 applies force to the expansion cavity 7, the expansion cavity 7 returns, water entering the inner part is discharged to the first water outlet 3 through the expansion waterway 72, and the water pressure discharged under pressure acts on the valve ball 6, so that the valve ball 6 stops pressing against the sealing gasket to keep sealing. If the impeller stops rotating anticlockwise, the preset pressure of the pressure chamber 8 acts on the valve ball 6 through the residual water pressure, so that the valve ball 6 stops pressing against the sealing gasket to keep sealing.
Further preferably, the outer wall of the expansion portion of the expansion chamber 7 is an elastic film 71 which is impermeable to water and air.
The foregoing is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.
