Description
Technical field
The utility model relates to filter, specifically refers to the oily primary filter of secondary.
Background technology
Current oil filter is widely used in the purified treatment to hydraulic oil, hydraulic transmission oil, gear oil, gasoline engine oil, diesel engine oil, compressor oil, refrigerator oil and heat treatment wet goods, oil filter can moisture, gas and mechanical admixture in fast eliminating oil, light acids, light hydrocarbon etc. are removed in flash distillation, and then improve the quality of oil, reply the serviceability of lubricating oil, ensure the normal operation of dynamical system, hydraulic system, lubricating system.And the element kit of through type filter of the prior art comprises two parts substantially, i.e. filter stand and filter screen, element kit is become by molten tin welding, the filtering accuracy of this element kit is 80 orders, and when highly pressurised liquid passes through, medium contains small metal particles can enter hydraulic system by filter screen, hydraulic valve and jack are polluted, reduce the service life of valve and jack, even can occur malfunction because of the seal failure of hydraulic valve, cause the person and equipment breakdown.
And traditional primary filter for iundustrial oil, the common filter of usual employing is to process the major diameter impurity particle etc. in iundustrial oil, but in iundustrial oil injection process, current at a high speed cause larger impact to filter, and swiftly flowing impurity particle can form serious wearing and tearing to parts each in filter thereupon, greatly reduce the service life of filter, the solution adopted in prior art is directly carry out regulating the charge velocity of iundustrial oil by valve, but machinery valve needs artificial constantly manual adjustments, increase the weight of the work load of staff, the filter efficiency of iundustrial oil is reduced greatly.
Utility model content
The purpose of this utility model is to provide secondary oily primary filter, automatically regulates the iundustrial oil flow by filter, reduces the impact wear to filter interior, and then reach the object of protection filter.
The purpose of this utility model is achieved through the following technical solutions:
The oily primary filter of secondary, comprise cylindrical shell and be opened in oiler and the oil-out at the upper and lower two ends of cylindrical shell, in described cylindrical shell, division board is installed, the two ends of described division board have multiple discharge orifice, also comprise the base for supporting be fixed in cylindrical shell, slide in base for supporting and be provided with motion bar, groove is provided with in the lower end of base for supporting, the lower end of motion bar is connected with bottom portion of groove by spring, the upper end of motion bar is run through division board and is had block at its end winding support, described block is just to oiler, described block comprises the body of truncated cone-shaped, rotate on described body top and be provided with ball, and annular is provided with multiple guiding gutter along tubular axis direction on the outer wall of described body, baffle plate is fixed with at the middle part of motion bar, when spring is positioned at initial position, the position of baffle plate is configured to, multiple discharge orifice blocks by the upper surface of baffle plate.During utility model works, iundustrial oil enters into inner barrel from oiler, direct effect is got on block, when iundustrial oil flow increases and flow velocity is accelerated, the stress be applied on block increases, namely stress is sent on spring by motion bar by block, spring stress is compressed, the baffle plate be now positioned on motion bar moves down with motion bar, and then baffle plate and division board are departed from, the iundustrial oil injecting inner barrel directly flows out from the multiple discharge orifices division board, iundustrial oil flow is larger, when flow velocity is faster, spring is higher by the degree compressed, namely the oil mass flowed out by discharge orifice is larger, and then realize discharging from oil-out of large discharge fluid, when iundustrial oil flow reduce and reduced velocity flow time, the applied stress that spring is subject to reduces, and is popped up by motion bar after the deformation that spring-return is certain, until when stopping injecting fluid, baffle plate contacts again with division board, and then stops fluid to continue to inject from discharge orifice, realize the flow-control of fluid in cylindrical shell by the up-down adjustment of motion bar, and then reduce fluid to the impact of cylindrical shell, reach the object of protection filter,
Wherein, block comprises the ball that the body of truncated cone-shaped and rotation are arranged on bodies top, when swiftly flowing fluid injects inner barrel, motion bar is stressed move down before, fluid is applied directly to above ball, due to the instability of the flow rate of fluid, therefore ball can start freely to rotate under the impact of fluid, and the flow direction of the fluid of the overwhelming majority changes when rotating, the parabolic motion of horizontal direction is become from perpendicular flow direction, discharge orifice is entered under the bounce-back of cylinder inboard wall, small part does not move fluid that direction changes and then slides in discharge orifice under guiding gutter arcuately, by the classification process of block to fluid, impact to motion bar when greatly reducing fluid flow at high speed, make motion bar more flexible in the process regulating fluid throughput, protect the spring in rectangular recess to there will not be the stressed or phenomenon of the power of mistake suddenly simultaneously, reduce the metal fatigue degree of spring, improve the service life of device.
Further, also comprise filter screen, described filter screen to be fixed in cylindrical shell and to be placed in the top of block.Be arranged in cylindrical shell and just primary filter carried out to the large straight granule foreign etc. that the iundustrial oil of injection can mix by the filter screen of oiler, prevent from occurring clogging when carrying out essence filter to iundustrial oil.
Further, also comprise sealing gasket, have rectangular recess in the lower end of described division board, described sealing gasket is fixed in rectangular recess, and the inwall of sealing gasket contacts with the outer circle wall of motion bar.Motion bar can slide up and down in division board, the fluid entered in cylindrical shell easily enters cylindrical shell bottom along the gap between motion bar and division board, the utility model offers rectangular recess in division board lower end, by installing sealing gasket to prevent fluid in advance by the lower end of leaking under the upper end of division board to division board in rectangular recess.
The utility model compared with prior art, has following advantage and beneficial effect:
1, the utility model when iundustrial oil flow reduce and reduced velocity flow time, the applied stress that spring is subject to reduces, and is popped up by motion bar after the deformation that spring-return is certain, until when stopping injecting fluid, baffle plate contacts again with division board, and then stops fluid to continue to inject from discharge orifice; Realize the flow-control of fluid in cylindrical shell by the up-down adjustment of motion bar, and then reduce fluid to the impact of cylindrical shell, reach the object of protection filter;
2, the utility model is arranged in cylindrical shell and just carries out primary filter to the large straight granule foreign etc. that the iundustrial oil of injection can mix by the filter screen of oiler, prevents from occurring clogging when carrying out essence filter to iundustrial oil;
3, motion bar of the present utility model can slide up and down in division board, the fluid entered in cylindrical shell easily enters cylindrical shell bottom along the gap between motion bar and division board, the utility model offers rectangular recess in division board lower end, by installing sealing gasket to prevent fluid in advance by the lower end of leaking under the upper end of division board to division board in rectangular recess.
