Abstract
The combined oil filtering device outside the tank is suitable for controlling oil impurities at an inlet and an outlet of a hydraulic system. The device consists of a two-position three-way ball valve, two oil filters with filter element direct connection protection valves, a differential pressure transmitter and a bracket. Can be arranged on the box and outside the box. When the system is in operation, a signal is sent out after the filter element is blocked. Pulling the handle can cut off the blocked oil filter and simultaneously switch on another oil filter, so that the system can continue to operate. After conversion, the filter element can be taken out for cleaning or replacement when convenient. The device has the characteristics of no need of opening the box, no shutdown, no pollution, simple conversion, convenient maintenance and the like. And can prevent the functions of air suction, overload, system safety protection and the like caused by cold start or filter element blockage.
Description
The utility model belongs to the hydraulic pressure auxiliary.
The maximization of hydraulic means, precise treatment, automation are more and more higher to the performance and the structural requirement of oil filter.And single oil filter disadvantage of installing in the case that hydraulic system adopts at present is a lot, must unpack after stopping up as filter core and put drier oil liquid, unloads oil filter and just can clean or change.Need long-time shutdown maintenance, and work situation is poor, is unfavorable for pollution management, and system is stopped up because of cold start or filter core are serious cause security of system and filter core diabrosis prevention ineffective.
The purpose of this utility model provides and does not a kind ofly influence that system normally moves, new molding box easy to maintenance, automatic protection makes up oil-filtering apparatus outward.
The utility model by oil filter, the pressure reduction of two-position three way spherical plug valve, two straight-through protective valves of band filter core send out device fast, holder segment forms.Rotary valve both sides symmetry connects two oil filters.Differential pressure transmitter device is fixed on the oil-filter shell.Fixed mount is fixed on rotary valve bottom surface or trailing flank.
The two-position three way spherical plug valve is made up of handle 3, valve rod (not drawing among the figure), spheroid 18, positioning disk 16, seal 17, valve body 2.Handle 3 cooperates with valve rod in insertion spheroid 18 upper slots, and spheroid 18 is fixed by two positioning disks that seal 17 is housed, and pad (drawing among the figure) is adjusted.Positioning disk is fixed on the valve body 2, and is connected with oil filter flange 14.Valve body 2 is a three way type.The spheroid 18 two garden cavitys that meet at right angles communicate.
Oil filter is made up of housing 13, cap 5, filter core 12, spring 6.The straight-through protective valve of filter core that interior dress is made up of valve gap 10, seal 11, spring 9, guiding oil inlet pipe 7 is fixed on the cap 5.Housing 13 tail bands have that seam, top are flanged, oil-in is arranged at the bottom, and the middle and upper part links to each other with flange 14.Cap 5 has the fast device hydraulic fluid port of two Kong Yufa to communicate.The hole that is positioned at axis links to each other with guiding oil inlet pipe 7.Cap 5 usefulness screws 8 are fixed on housing 14 upper flanges.There is round tube hole at filter core 12 two ends, and the lower end is with seam location, housing 13 bottom.Bottom convex and net constitute the cross section and are the U type and receive dirty groove A, and spring 6 compresses filter core 12 upper ends.Guiding oil inlet pipe 7 hollows, following band convex shoulder, the upper end links to each other with housing, and filter core 12 inner chambers are stretched in the lower end.Seal 11, valve gap 10 hollows are nested with guiding oil inlet pipe 7, are compressed seal 11 and are sealed filter core 12 upper end holes by spring 9.
The utility model is compared with existing oil filter, have can be directly installed on the case, the case side, having the maintenance of unpacking, realizing the long-term closure of fuel tank; The filter core obstruction can be changed the system of not influencing fast and normally move; The maintain and replace filter core is convenient, does not pollute, and filter core stops up pressure reduction sender cold start or can safeguard protection when seriously stopping up, in case advantage such as that pump is inhaled is empty, system overload and filter core diabrosis, and flow is big, the pressure loss is little.

Embodiment:
So that the oil suction combination oil-filtering apparatus that is threaded to be installed on XZUQ-A100 * 80LX molding box is example:
Two oil filter centre-to-centre spacing are that 290mm bracket bottom identity distance rotary valve center is 70mm device height overall 270mm.
Rotary valve valve body 2 length * wide * high 74 * 80 * 80mm epirelief, one round platform φ 42mm apart from center 49mm oil-out diameter phi 32mm, have M42 * 2 internal threads outward, external diameter φ 70mm, tip to face distance center 60mm.Spheroid 18 external diameter φ 60mm, the hole, right angle is φ 32mm, the long 48mm of end face, positioning disk external diameter are respectively φ 110mm and φ 65mm, long 20mm and the 17mm, hollow diameters φ 32mm of being respectively.Seal 17 external diameter φ 53mm, internal diameter φ 32mm, long 11mm, 45 ° of taper holes, material are nylon 1010.Positioning disk 16 is connected by screw 19 with valve body 2, and 4 pitch-rows 60 * 60, distribute alternately at the M8 screw.Oil filter housing 13 length overall 230mm, external diameter φ 90mm, upper flanges external diameter φ 135mm, middle outside weldering flange outer diameter φ 135mm, apart from rotary valve center 70mm, the high 190mm of inner chamber, seam φ 71mm, oil-in M42 * 2 oil-outs are apart from upper surface 40mm.Filter core 12 is of a size of φ 71 * 153 and is net formula filter element filtering precision 80 μ, and two stomidiums are φ 32mm.Oil-feed guide pipe 7 long 45mm, outer internal diameter φ 15 * φ 10, M12 lower end, upper end φ 18 long 2mm.Protection valve gap external diameter is that φ 42 and φ 25 corresponding length are respectively 5mm, 15mm, and internal diameter is φ 15mm.Seal outer diameter φ 45mm, internal diameter φ 15mm, thick 4mm.Material is that oil resistant rubber I-1 spring 6 is φ 55 * 5 * 50 * 10, and material is the carbon spring steel wires II, and spring 9 is φ 20 * 1.6 * 45 * 5.97 material carbon spring steel wires II.Oil filter cap 5 external diameter φ 135 thick 15mm, oilhole are apart from 36mm, diameter phi 8mm, signalling generator model C S-II type, sender value 0.03MPa.Pull handle to left side plate extreme position (accompanying drawing 2 shown positions), then fluid is gone into filter core 12 inner chambers by left oil filter bottom hydraulic fluid port, enter rotary valve through filter screen to exocoel and enter hydraulic pump by outlet through spheroid 18, fluid also enters through guiding oil inlet pipe 7 and to send out device 1 oil-in fast, enters signalling generator 1 another hydraulic fluid port by filter core 12 exocoels through cap 5.Impurity was filtered two net filtrations and was deposited on and receives in the dirty groove this moment.After filter core stops up, the filter core inside and outside differential pressure is increased, when reaching sender setting value 0.03MPa.Signalling generator 1 sends signal.Pull 90 ° on handle this moment to the limit on the right-right-hand limit position, then stop up oil filter and be cut off fluid and enter rotary valve from fuel tank through right oil filter and go out.System continues normal operation.Can unload lower cover 5 at a convenient time, take out the filter core 12 that stops up and clean or change.Send and in time do not change pressure reduction and can increase when system is in cold start or signal, when reaching secure setting 0.04MPa, then fluid is opened protection valve gap 10 and is directly entered oil pump through filter core 12 upper end holes, prevents to inhale empty and filter core diabrosis.
