Liquid pipe；The utility model is structurally reasonable, integrates decompression, cooling, pours water, easy to use, and water column is effectively reduced to bottom valve
Impact force extends the service life of water pump, reduces cost.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
In figure: 1. valve bodies；2. upper flange；3. the first adapter tube；4. lower flange；5. the second adapter tube；6. spool；7. channel；
8. plug；9. liquid-feeding tube；10. vertical adapter tube；11. bend pipe；12. horizontal nozzle；13. valve；14. outlet(discharge) flange.
Specific embodiment
In order to be more clear the goal of the invention, technical solution and its advantageous effects of the utility model, below in conjunction with
The drawings and specific embodiments, the present invention will be further described in detail；
In the accompanying drawings: a kind of cooling charging valve of water pump decompression, it is characterised in that: the decompressor of collection reduction water column pressure,
Irrigation device, cooling device are in one；The decompressor includes valve body 1, and upper flange 2, upper flange are provided with above valve body 1
It is connected between 2 and valve body 1 by the first adapter tube 3；It is provided with lower flange 4 below valve body 1, passes through between lower flange 4 and valve body 1
Second adapter tube 5 is connected；Valve body 1 is internally provided with the spool 6 of control flow；The cooling device includes leading on the left of valve body 1
The channel 7 of cooling water, 7 outer end of channel are provided with plug 8；The irrigation device includes the cylinder that 1 left side of valve body is arranged in
Liquid-feeding tube 9, liquid-feeding tube 9 is by the way that adapter tube 10, bend pipe 11, horizontal nozzle 12 are connected with the second adapter tube 5 vertically；On vertical adapter tube 10
It is provided with the valve 13 that Controlled irrigation device opens or closes.
The channel 7 it is orthogonal with 1 inner wall of valve body and with communicated inside valve body 1；The lower flange 4 and water pump
Outlet(discharge) flange 14 is connected, and connection type is to be bolted；The liquid-feeding tube 9 is vertically arranged；The upper flange 2 and
Between one adapter tube between the 3, first adapter tube 3 and valve body 1, between valve body 1 and the second adapter tube 5, between the second adapter tube 5 and lower flange 4
It is all made of welded connecting.
The specific implementation of the utility model: before water pump booting, opening the valve 13 of liquid-adding device, water added into liquid-feeding tube 9,
Until liquid-feeding tube 9 is filled it up with, water pump can be opened by shutting valve 13；During pump working, since high speed rotation leads to pump shaft temperature
Degree rises, at this point, cooling tube is connected with the interface on decompressor, leads to cooling water to water pump, effectively cooling pump shaft sleeve；Water pump
When shutdown, the water column of generation is depressurized by the spool 6 in decompressor, acts on water column active force on entire valve body, effectively
Water column is reduced to the stamping press of water inlet bottom valve, prevents from being broken into water bottom valve, extends the service life of water pump.
