Abstract
The utility model discloses an exhaust device for the oil absorption pipeline of an oil pump, and aims to solve the present problems that when oil with bubbles enters into the high-pressure cavity of the oil pump, local high-frequency pressure shock is formed, and noise and vibration are generated, which causes the damage on the oil pump. The exhaust device comprises the transversal oil absorption pipeline communicated with an oil tank; and the oil pump is connected to the oil absorption pipeline. The exhaust device is characterized in that a vertical exhaust pipe is communicated with a position at the upper part of the oil absorption pipeline; a gate valve is mounted on the exhaust pipe; and a splash-proof valve is mounted at the top end of the exhaust pipe. The utility model has the advantages that gas in the oil in the oil absorption pipeline can be exhausted more easily; the conditions of air absorbed in the oil pump during work can be effectively improved; the service life of the oil pump can be prolonged; and the normal operation of a hydraulic system can be guaranteed.
Description
Technical field
The utility model relates to a kind of oil pump suction tube road venting gas appliance.
Background technique
In metallurgy industry, hydraulic equipment is used general, and is mostly the large hydraulic system, and pressure is high, flow is big, and reservoir capacity reaches thousands of liters up to ten thousand that rise to.Because system is huge, hydraulic element such as pump, valve, oil cylinder are numerous, and hydraulic tubing gathers.When handling these elements, pipe coupling fault, can sneak into a lot of air in the system.Influenced by rhythm of production and personnel's level of skill, these air of sneaking into can not obtain getting rid of mostly, under the effect of pressure oil, become the bubble state, finally get into fuel tank through return tube.
Generally be provided with air-strainer as venting gas appliance at the fuel tank top, be mixed in air in the oil behind release of pressure with bubble shape, portion gas can be overflowed from oil and discharge through air-strainer.But receive Oiltank structure and system oil return flow, the oil pump oil suction flow that is connected with fuel tank and get into what the influence of fuel tank air, a part of gas also has little time from oil, to overflow, and just under the oil pump pumping action, gets in the fuel sucking pipe.And fuel sucking pipe does not normally have venting gas appliance.Therefore, when the fluid that has a bubble got into the hyperbaric chamber of oil pump, bubble was broken up, and form local high-frequency pressure and impact, thereby produce noise, vibration, to the oil pump infringement greatly, and if things go on like this, with the working life that has a strong impact on oil pump.
The model utility content
The purpose of the utility model is to overcome the existing technology defective, and a kind of oil pump suction tube road venting gas appliance is provided.
The technological scheme of the utility model is achieved in that a kind of oil pump suction tube road venting gas appliance; Comprise the horizontal oil-absorbing pipeline that is communicated with fuel tank, be connected with oil pump on the oil-absorbing pipeline, it is; Be communicated with vertical outlet pipe at the oil-absorbing pipeline upper position, be equipped with gate valve on the outlet pipe.
It is that said outlet pipe height is higher than the fuel tank liquid level height.
It is that said outlet pipe is positioned on the end position of oil-absorbing pipeline.
It is that said outlet pipe top is equipped with plash proof valve, and plash proof valve is made up of valve seat, valve gap, retaining plug cock, exhaust port; Valve seat and valve gap concave surface form exhaust cavity relatively, and valve seat and valve gap are with being threaded together, and outlet pipe passes valve seat and is communicated with exhaust cavity; Be equipped with the retaining plug cock with valve seat outlet pipe relative position on the valve gap, the retaining plug cock screws in valve gap through the spiral shell button, also has exhaust port on the valve gap; Gas gets into exhaust cavity through outlet pipe in the oil, discharges from exhaust port again.
It is that said exhaust port is located on the valve gap periphery facade.
It is that said exhaust port is covered with filter screen.
The utility model can help the gas in the oil-absorbing pipeline oil to discharge, and sucks the situation of air in the time of improving oil pump work effectively, prolongs the working life of oil pump, guarantees the normal operation of hydraulic system.

Fig. 2 is the plash proof valve structural representation.
Among the figure, the 1-fuel tank, the 2-oil-absorbing pipeline, the 3-oil pump, the 4-gate valve, the 5-outlet pipe, the 6-plash proof valve, the 7-valve seat, the 8-valve gap, 9-keeps off plug cock, 10-exhaust port, 11-exhaust cavity, 12-filter screen, 13-pipe collar.
Embodiment
Further describe below in conjunction with accompanying drawing.
As shown in the figure, a kind of oil pump suction tube road venting gas appliance comprises the horizontal oil-absorbing pipeline 2 that is communicated with fuel tank 1; Be connected with oil pump 3 on the oil-absorbing pipeline 2; Be communicated with vertical stainless steel outlet pipe 5 at oil-absorbing pipeline 2 upper positions, outlet pipe 5 internal diameters are Φ 16mm, thickness of pipe wall 1.5 ~ 2mm, are equipped with gate valve 4 near bottom position on the outlet pipe 5; Outlet pipe 5 highly is higher than the about 200mm of liquid level height in the fuel tank 1; Oil pours out when avoiding exhaust, and outlet pipe 5 is positioned on the end position of oil-absorbing pipeline 2, concentrates at this in order to gas in the oil and discharges.During operation; The hydraulic oil that is mixed with air in the fuel tank 1 gets into oil-absorbing pipeline 2; Gas floats over the top of oil-absorbing pipeline 2, opens the gate valve 4 on the outlet pipe 5, and the air that accumulates in oil-absorbing pipeline 2 tops will be discharged along outlet pipe 5 continually; Like this, the gas in the fluid of entering oil pump 3 oil sucting cavities will significantly reduce or not contain gas.
When considering, have a small amount of hydraulic oil sometimes and spray, therefore, a plash proof valve 6 is installed on outlet pipe 5 tops with air through outlet pipe 5 free exhausts.When oil gas ejection during through plash proof valve 6, be mixed in hydraulic oil in the gas in-line arrangement tracheae 5 that in plash proof valve 6, is obstructed and flow back to downwards in the oil-absorbing pipeline 2, air is discharged then unblockedly.
Above-mentioned plash proof valve 6 is made up of valve seat 7, valve gap 8, retaining plug cock 9, exhaust port 10.Specifically: valve seat 7 forms exhaust cavity 11 relatively with valve gap 8 concave surfaces, and valve seat 7 is threaded together with valve gap 8 usefulness, and valve seat 7 is welded on the outlet pipe 5; Outlet pipe 5 passes valve seat 7 and is communicated with exhaust cavity 11; Be equipped with retaining plug cock 9 with valve seat 7 inside exhaust pipes 5 relative positions on the valve gap 8, retaining plug cock 9 screws in valve gap 8 through the spiral shell button, and screw-in depth is looked required the oily effect of retaining and decided; Also have plurality of rows pore 10 on the valve gap 8 peripheral facades; When gas mixture when outlet pipe 5 sprays into exhaust cavity 11, the fluid in the gas is kept off plug cock 9 to be stopped and falls, in the oil gas then the exhaust port 10 around the retaining plug cock 9 discharge.For preventing that dust from getting into, be covered with filter screen 12 in exhaust port 10 outsides, filter screen 12 usefulness pipe collars 13 are fixed on valve gap 8 outer walls.
