Abstract
The utility model discloses a cooling water control device of a shaft seal stuffing box for a pump, comprising a connecting pipeline used for communicating a supply end of cooling water and a cooling cavity of the shaft seal stuffing box for the pump, wherein the connecting pipeline is provided with a flow metering valve, the input end of which is connected with the supply end of the cooling water and the output end of which is communicated with the connecting pipeline; and a pressure check device is arranged between the output end of the flow metering valve and the connecting pipeline and is communicated with the connecting pipeline. The cooling water control device can reduce the mechanical loss of the pump, improve the work efficiency of the pump, and is easy to guarantee the leak tightness of the shaft seal and effectively prolong the service life of the shaft seal stuffing box.
Description
Technical field
The utility model relates to a kind of pump shaft envelope stuffing box cooling water control device.
Background technique
When the axle envelope of pump adopts packing seal traditionally, stuffing box must be introduced cooling water filler is cooled off and lubricates, and cooling water often attracts by a pipe from the zone of high pressure of pump itself, and this cooling and lubricating water must allow the leakage of a little in packing seal place.But, there is deficiency in this mode when the pressure of pump own is higher: because the cooling and lubricating water pressure that attracts from the pump zone of high pressure is higher, leak for making stuffing box be unlikely to transition, must push filler very tight by the nut that screws on the Gland, so that the filler seize is very tight, the filler seize is tight more, and its frictional force is big more, and the power loss of pump is also big more; Otherwise filler is pressed not tightly, and sealing effect is just poor more, and shaft sealing leakage is serious.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of mechanical loss that can reduce pump is provided, increases work efficiency and guarantees easily the pump shaft envelope stuffing box cooling water control device of axle envelope sealing.
Goal of the invention of the present utility model is to realize like this, a kind of pump shaft envelope stuffing box cooling water control device, comprise and be used to be communicated with the supply side of cooling water and the connecting pipeline that pump shaft seals the cooling chamber of stuffing box, it is characterized in that: described connecting pipeline is provided with flow control valve, the input end of flow control valve is connected with the supply side of cooling water, and the output terminal of flow control valve is communicated with connecting pipeline.
Be provided with the inspection pressure device between the output terminal of described connecting pipeline and flow control valve, the inspection pressure device is communicated with connecting pipeline.
Described connecting pipeline is provided with tee union, and first end connector of tee union is communicated with control valve, and second end connector of tee union is connected with connecting pipeline, and the 3rd end connector of tee union is connected with the inspection pressure device.
Be provided with filter between described control valve and tee union first end connector.
Described filter is a y-type filter.
Be provided with the cutting ferrule joint between described connecting pipeline and the pump shaft envelope stuffing box cooling chamber.
Described inspection press-fits and is changed to pressure gauge.
Described control valve is a flow control valve.
The utility model is by improving existing pump shaft envelope stuffing box cooling water control device, set up y-type filter, pressure gauge, tee union between control valve and connecting pipeline, the stuffing box cooling water flow enters the shaft packing letter behind control valve, Y shape filter, tee union, connecting tube.When the pressure of pump zone of high pressure is higher, regulate the cooling water that minimizing enters stuffing box by control valve, thereby the pressure of cooling water in the reduction stuffing box, Y shape filter filters particulate matter contained in the cooling water of self-pumping zone of high pressure, assurance enters the cooling water cleaning of stuffing box, pressure gauge is by the tee union pressure, to monitor the pressure of the cooling water that enters stuffing box by pressure gauge, thereby reach better sealing effect, reduce the frictional force of filler, reduce the mechanical loss of pump axle sleeve and axle generation.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model most preferred embodiment.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
According to shown in Figure 1, pump shaft envelope stuffing box cooling water control device of the present utility model, comprise and be used to be communicated with the supply side of cooling water and the connecting pipeline 2 that pump shaft seals the cooling chamber of stuffing box, this connecting pipeline 2 is provided with flow control valve 1, the input end of flow control valve 1 is connected with the supply side of cooling water, and the output terminal of flow control valve 1 is communicated with connecting pipeline 2.Be provided with inspection pressure device 3 between the output terminal of connecting pipeline 2 and flow control valve 1, this inspection pressure device 3 is a pressure gauge.Inspection pressure device 3 is communicated with connecting pipeline 2, connecting pipeline 2 is provided with tee union 4, first end connector of tee union 4 is communicated with control valve 1, and second end connector of tee union 4 is connected with connecting pipeline 2, and the 3rd end connector of tee union 4 is connected with inspection pressure device 3.Inspection pressure device 3 monitors the pressure of the cooling water that enters stuffing box by tee union 4 pressures by inspection pressure device 3.Be provided with filter 5 between control valve 1 and tee union 4 first ends, this filter 5 is a y-type filter, and Y shape filter 5 filters contained particulate matter in the cooling water of self-pumping zone of high pressure, guarantees the cooling water cleaning that enters stuffing box.Connecting pipeline 2 and pump are with being provided with cutting ferrule joint 6 between the stuffing box cooling chamber, control valve 1 is a flow control valve.When the pressure of pump zone of high pressure is higher, can and then reduce the cooling water that enters stuffing box by control valve 1 adjusting, reduce the pressure of cooling water in the stuffing box, after cooling water enters stuffing box, on the one hand toward the pump chamber internal leakage, leak along the Gland end on the other hand, the cooling water that enters stuffing box makes its pressure keep being advisable than the about high 0.1MPa of pump chamber internal pressure by the adjusting of control valve 1.The utility model is applicable to the Flow-rate adjustment and the pressure control of the shaft packing letter cooling water of general pump, is specially adapted to the Flow-rate adjustment and the pressure control of high-pressure service pump stuffing box cooling water.
