Abstract
The utility model relates to an air exhausting device for diesel engine water pump, which comprises a pump and an engine. Wherein, outflow tube wall of the pump is provided with a hollow screw whose another end is connected to a filter and a bi-directional valve through pipeline; the other end of the bi-directional valve is connected to a discharge outlet of a diesel engine filter through the pipeline. In operation, the pump outlet and the diesel engine filter air inlet should be sealed firstly, the pipeline on the filter discharge outlet should be taken off and the bi-directional valve be fixed into it; then the engine be started up and the air would be drawn out by the intake pipe; the water flows into the pump body and then into the bi-directional valve through the filter; then the hollow valve floats upward to contact with the B end with its shell; then the valve be closed, the pipeline on the filter discharge outlet should be taken off and the pump be started up; the water level inside the valve shall descend if poor sealing is conducted to the bottom valve of the pump inlet branch; the A end of the hollow valve contacts the valve shell to prevent the water flowing backward. The utility model is characterized in simple structure, convenient use, time and labor saving, safety and efficiency.
Description
Technical field
The utility model relates to a kind of suction pump fixture, specifically a kind of diesel engine suction pump air emptier.
Background technique
We know that water and mainly drive water pump with diesel engine in the farmland, rural area at present.This device major defect is, before drawing water, just can draw water after must at first adding the diversion evacuation of air.During use, inconvenience very.At present existing products adopts and makees skirt on the diesel engine intake pipe, utilizes machine power that the air in water pump and the intake pipe is discharged, and has saved the process of water, but its product structure more complicated during production costs and the cost height, should not be promoted practicality.
Summary of the invention
The utility model provides a kind of simple in structure, easy to use, time saving and energy saving diesel engine suction pump air emptier for overcoming above-mentioned the deficiencies in the prior art.
The purpose of this utility model is to adopt following technical proposals to realize: a kind of diesel engine suction pump air emptier, it includes water pump and diesel engine, on the water pump water outlet tube wall, be provided with a cored screw, the other end of cored screw is connected on filter and the two-way valve by pipeline, and the other end of two-way valve is connected on the sewage draining exit on the diesel filter by pipeline.
Described two-way valve is that the hollow body that both sides are provided with taper is set in the valve body.
The utility model adopts and be connected to diesel filter by cored screw, filter, two-way valve on water pump.During use, at first with exit of pump and diesel filter suction port good seal, take off the blowdown flap on the filter cleaner again, two-way valve is fixed on the sewage draining exit by pipeline, the two-way valve of this moment is preferably vertically placed.After finishing above-mentioned steps, start diesel engine, the diesel engine intake pipe begins will to extract out in air from pump body and the intake pipe by this device; At this moment, though the hollow valve body in the two-way valve body because of gravity sag, A end contact with valve body, owing to the effect of negative pressure, still can be so that air flows to filter cleaner through the gap that A holds.After the utility model work a period of time, water reaches the pump housing, and arrives in the two-way valve by filter, because buoyancy of water, and the density of hollow core valve is littler than water, the hollow valve body come-up, and make B end in contact two-way valve housing gradually, with valve closing.After finishing above-mentioned steps, two-way valve is taken off with the pipeline that the filter cleaner sewage draining exit is connected, and start water pump, in this process,, can make drawdown in the valve if pump water inlet bottom valve seal is bad; With the decline of water level, hollow valve body descends, and A end in contact valve casing has played the effect of sealing, effectively the refluence of anti-sealing.The utlity model has characteristics such as simple in structure, easy to use, time saving and energy saving, safe and effective.
Description of drawings
Accompanying drawing is the utility model structural representation.
1. pumping lines among the figure, 2. cored screw, 3. pipeline, 4. filter, 5. two-way valve, 6. hollow body, 7. filter cleaner, 8. sewage draining exit.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Structure is provided with a cored screw 2 as shown in drawings on pumping line 1 wall, the other end of cored screw 2 is connected on filter 4 and the two-way valve 5 by pipeline 3, and the other end of two-way valve 5 is connected on the sewage draining exit 8 on the diesel filter 7 by pipeline 3.Two-way valve 5 is that the hollow body 6 that both sides are provided with taper is set in the valve body
Working procedure of the present utility model is as follows: at first with exit of pump and diesel filter 7 suction port good seals, take off the blowdown flap on the filter cleaner 7 again, two-way valve 5 is fixed on the sewage draining exit 8 by pipeline 3, the two-way valve 5 of this moment is preferably vertically placed.After finishing above-mentioned steps, start diesel engine, the diesel engine intake pipe begins will to extract out in air from pump body and the intake pipe by this device; At this moment, though the hollow body 6 in the two-way valve body because of gravity sag, A end contact with valve body, owing to the effect of negative pressure, still can be so that air flows to filter cleaner 7 through the gap that A holds.After the utility model work a period of time, water reaches the pump housing, and arrives in the two-way valve by filter 4, because buoyancy of water, and the density of hollow body 6 is littler than water, hollow 6 bodies come-up, and make B end in contact two-way valve 5 housings gradually, with valve closing.After finishing above-mentioned steps, two-way valve 5 is taken off with the pipeline that filter cleaner sewage draining exit 8 is connected, and start water pump, in this process,, can make drawdown in the valve if pump water inlet bottom valve seal is bad; With the decline of water level, hollow body 6 descends, and A end in contact valve casing has played the effect of sealing, effectively the refluence of anti-sealing.
Claims (2)
1. diesel engine suction pump air emptier, it includes water pump and diesel engine, it is characterized in that: on the water pump water outlet tube wall, be provided with a cored screw, the other end of cored screw is connected on filter and the two-way valve by pipeline, and the other end of two-way valve is connected on the sewage draining exit on the diesel filter by pipeline.
2. the air emptier of diesel engine suction pump according to claim 1 is characterized in that: described two-way valve is that the hollow body that both sides are provided with taper is set in the valve body.
