Abstract
The utility model discloses a mining emulsion pump station oil-saving structure. The mining emulsion pump station oil-saving structure is characterized in that a reflow tee is serially connected to an inlet of an overflow valve of an emulsion pump station combined valve; a front one-way valve, a rear one-way valve and an inflow tee are serially connected to an oil incoming pipe of an emulsion pump station pump block; the inflow tee is arranged between the front and rear one-way valves; operating pressure of the one-way valves is smaller than that of the overflow valve and larger than inlet pressure of the pump block; the reflow tee and the inflow tee are communicated through a reflow pipeline. When a hydraulic support system stops using liquid or uses less liquid, hydraulic pressure of the combined valve rises and rises to rated pressure, and emulsion flows into the inflow tee through the reflow pipeline first; reflow pressure is higher than oil incoming pressure, oil incoming is blocked, and the pump block admits not oil but water; when the hydraulic pressure of the combined valve reaches the rated pressure, the overflow valve overflows finally non-oil clear water only, and waste of emulsion is prevented accordingly.
Description
Technical field
The utility model relates to the emulsion power pack that under coal mine, support system is used.
Background technique
Under coal mine, in hydraulic prop system, need emulsion power pack to produce hydraulic power.The emulsion power pack approaching with the application of use at present, be that oil emulsion and water enter the pump housing in proportion by be provided with the pump housing and combinaing valve body on chassis, after pump housing pressurization, enter combinaing valve body, water and oil are mixed into high-pressure emulsion in combinaing valve body, by pipeline supply hydraulic prop system; On combinaing valve body, be provided with in addition relief valve and spill pipe, in the time that hydraulic prop system stops reducing by liquid or fluid volume, the hydraulic pressure of combinaing valve body can rise, and rises while reaching rated pressure, and relief valve is opened unnecessary emulsified liquid unloaded discharge from spill pipe.Owing to containing the oil emulsion of a certain proportion of price in emulsified liquid, cause the waste of oil emulsion.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, designs a kind of mine-used emulsion pump station oil saving structure.
A kind of mine-used emulsion pump station oil saving structure, it is characterized in that, it is in the relief valve import of emulsion power pack combinaing valve body, to be connected in series a return tee joint, on the oil inlet pipe of the emulsion power pack pump housing, be connected in series former and later two one-way valves and an inlet triplet for water, inlet triplet for water is between former and later two one-way valves, the working pressure of one-way valve is less than the working pressure of relief valve and is greater than the inlet pressure of the pump housing, and return tee joint and inlet triplet for water are communicated with reflux line.
Below by working principle, advantage of the present utility model is described, in the time that hydraulic prop system stops reducing by liquid or fluid volume, the hydraulic pressure of combinaing valve body can rise, rise while being about to reach rated pressure, first emulsified liquid enters inlet triplet for water by reflux line, because return pressure is greater than input pressure, blocking-up oil-feed, make the pump housing not oil-feed of only intaking, in the time that the hydraulic pressure of combinaing valve body reaches rated pressure, final relief valve only overflows the not clear water of oil-containing, thereby prevents the waste of emulsified liquid.
Brief description of the drawings
Fig. 1 is the utility model embodiment's principle schematic.
Marginal data, the 1-pump housing, 2-emulsion power pack combinaing valve body, 3-reflux line, 4-return tee joint, 5-relief valve, 6-one-way valve, 7-inlet triplet for water, one-way valve before 8-, 9-oil inlet pipe.
Embodiment
Mine-used emulsion pump station oil saving structure as shown in Figure 1, it is to be connected in series a return tee joint 4 in relief valve 5 imports of emulsion power pack combinaing valve body 2, one-way valve 8, rear one-way valve 6 and an inlet triplet for water 7 before being serially connected with on the oil inlet pipe 9 of the emulsion power pack pump housing 1, inlet triplet for water 7 is between front one-way valve 8 and rear one-way valve 6, the working pressure of front one-way valve 8 and rear one-way valve 6 is less than the working pressure of relief valve 5 and is greater than the inlet pressure of the pump housing 1, and return tee joint 4 and inlet triplet for water 7 use reflux lines 3 are communicated with.
