Description
Technical field
The utility model relates to the valve arrangements that one kind can adjust pumpage in real time.
Background technique
Pump class product in the long-term use, exist cause because of the abrasion of internal spare part pump internal leakage increase,
The appearance of the case where the problem of volumetric efficiency reduces, discharge capacity is gradually reduced, pumpage cannot be guaranteed use demand in order to prevent, is both needed to
The valve arrangement of pump is adjusted, guarantee pumpage.
Traditional valve arrangement is in adjustment process, it is necessary to shut down pump, return factory and office's reason, decompose valve arrangement, pass through increasing
Add the mode of adjusting gasket, increase shutter spring decrement, increases the pressing force between shutter spring and valve, to adjust pump
Discharge capacity.Operating procedure is complicated, more demanding to operating environment, does not allow directly to disassemble in place to use.
Summary of the invention
The purpose of the present invention
The purpose of this utility model provides a kind of valve arrangement that can adjust pumpage in real time.
Technical solution of the present invention:
A kind of valve arrangement that can adjust pumpage in real time, comprising: valve lid 1, valve body 2, valve bar 3, plug screw 4,
Shutter spring 6, valve 7, interference bush 8 and pump case 9；Valve lid 1 is threadedly coupled with valve body 2,2 lower end spiral shell of valve body
Line is connected and fixed with pump case 9, and 4 external screw thread of plug screw is connect with 2 internal screw thread of valve body, and valve bar 3 is inserted into the square groove of plug screw 4
Interior, shutter spring 6 is compressed by plug screw 4,7 both ends of valve, in the insertion of valve 7 interference bush 8 fixed with 9 interference of pump case.
Further include: sealing ring 5,5 sets of sealing ring guarantee to seal in 3 neck of valve bar.
When needing to adjust pumpage, the valve bar 3 inside valve body 2 is rotated in real time, plug screw 4 is with 3 turns of valve bar
It moves and linkage from top to bottom, causes spacing between plug screw 4 and valve 7 to change, realize the compression or rebound of shutter spring 6, governor valve
Pressing force between spring 6 and valve 7.
When pressing force reduces, pump discharge liquid will push 7 counter motion of valve, so that between valve 7 and interference bush 8
Gap increases, and causes pump discharge liquid to enter inside valve body 2, returns to the import of pump by hole for back flow, realizes that pumpage subtracts
It is small；Conversely, gap reduces between valve 7 and interference bush 8 when pressing force increases, prevent pump discharge liquid is back to pump
Import, so that pumpage be increased.
Beneficial effects of the present invention:
The utility model relates to the valve arrangements that one kind can adjust pumpage in real time, general work can be used only in place to use
Tool rotation valve bar, drives plug screw linkage from top to bottom, and the decrement of governor valve spring increases the pressure between shutter spring and valve
Clamp force realizes the function of adjusting pumpage in real time.Compared with traditional valve arrangement, the utility model can be realized according to client's need
The discharge capacity that pump is adjusted when realistic, effectively improves the maintenance efficiency of pumpage adjusting, improves the service efficiency of pump, can be applied to it
His similar product, and there is good promotional value.
Detailed description of the invention
Fig. 1 is the utility model governor valve device diagrammatic cross-sectional view.
Specific embodiment
Below by specific embodiment, the utility model is described in further detail.
A kind of valve arrangement that can adjust pumpage in real time, as shown in Figure 1, comprising: valve lid 1, valve body 2, valve
Bar 3, plug screw 4, sealing ring 5, shutter spring 6, valve 7, interference bush 8 and pump case 9；Valve lid 1 and 2 screw thread of valve body connect
It connects, 2 lower thread of valve body is connected and fixed with pump case 9, and 4 external screw thread of plug screw is connect with 2 internal screw thread of valve body, and valve
Bar 3 is inserted into the square groove of plug screw 4, and 5 sets of sealing ring guarantee to seal in 3 neck of valve bar, and shutter spring 6 is by 7 liang of plug screw 4, valve
Side pressure is tight, in the insertion of valve 7 interference bush 8 fixed with 9 interference of pump case.
It, can be by rotating the valve bar 3 inside valve body 2 in real time when needing to adjust pumpage, plug screw 4 is with valve
Bar 3 rotates and linkage from top to bottom, causes spacing between plug screw 4 and valve 7 to change, realizes the compression or rebound of shutter spring 6, reach
The purpose of pressing force between governor valve spring 6 and valve 7.When pressing force reduces, pump discharge liquid will push valve 7 reversed
Movement causes pump discharge liquid to enter inside valve body 2, pass through back so that gap increases between valve 7 and interference bush 8
Fluid apertures returns to the import of pump, realizes that pumpage reduces.Conversely, when pressing force increases, gap between valve 7 and interference bush 8
Reduce, prevent pump discharge liquid is back to pump inlet, thus the purpose that will realize that pumpage increases.
The utility model relates to the valve arrangements that one kind can adjust pumpage in real time, general work can be used only in place to use
Tool rotation valve bar, drives plug screw linkage from top to bottom, and the decrement of governor valve spring increases the pressure between shutter spring and valve
Clamp force realizes the function of adjusting pumpage in real time.
