Abstract
The utility model relates to a pressure difference type signaling device for oil filtration, which is provided with a casing, and one end of the casing is provided with a microswitch; a signaling cavity is arranged in the microswitch, a signaling mechanism composed of a magnetic block, a valve core and a pressure spring is arranged in the signaling cavity beside the microswitch. The other end of the casing is provided with a visual signaling body which comprises a carrier arranged on the casing and a painting display button connected with the magnetic block, and one end of the valve core near the painting display button is provided with an isomerism magnetic block which is attracted with the magnetic block. The painting display button is provided with an outer elastic pressure spring, and the signaling and visual functions can be realized by the oil pressure difference of oil filters before and after filtration. The utility model has the advantages of stable performance and high safety.
Description
The utility model relates to a kind of line filter that is used for and pollutes the differential oil strain signalling generator of reporting to the police.
During hydraulic work system; pollutant in the continuous intercepting system of filter stamen in the oil filter; make the filter stamen blocked gradually; the pressure of importing and exporting oil produces pressure reduction; when pressure difference increases to the signalling generator setting; signalling generator connection signal power supply is reported to the police automatically; existing differential signalling generator is usually by microswitch with by magnetic patch; spool; the sender mechanism that stage clip constitutes forms; when the import and export oil pressure difference of oil filter increases to setting; spool will overcome stage clip power together with magnetic patch and move toward the microswitch direction; adhesive microswitch action sender is because electrical equipment or circuit break down through regular meeting and cause not reporting to the police in the signalling generator.Cause turnover oil pressure difference excessive, break through oil filter filter stamen, pollution enters the workspace, loss machinery.
The purpose of this utility model is to overcome the defective of above-mentioned technology, provides a kind of and possesses electric sender simultaneously and order shows function, stable performance, safe and reliable differential oil strain signalling generator.
The utlity model has in housing, the housing and establish call-sending cavity, housing one end is provided with microswitch, be positioned at the other sender mechanism that constitutes by magnetic patch, spool and stage clip that is provided with of microswitch in the call-sending cavity, offer the fuel feed hole that is communicated with oil strain on the housing, the other end at housing is provided with eye-viewing signalling body, eye-viewing signalling body comprises the carrier that is installed on the housing, be associated with the demonstration knob of tinting of magnetic patch, near the setting of spool at this position and the magnetic patch different in nature magnetic patch of adhesive mutually, tinting shows that knob is provided with and suppresses spring outward.
Further specify the utility model below in conjunction with embodiment and accompanying drawing.
Accompanying drawing is the structure cutaway view of present embodiment.
Present embodiment has a housing 1, establish call-sending cavity in the housing 1, housing 1 one ends are provided with microswitch 7, be positioned at microswitch 7 other being provided with in the call-sending cavity by magnetic patch 8, the sender mechanism that spool 4 and stage clip 9 constitute, stage clip 9 one ends prop up the call-sending cavity end face, the other end props up spool 4 end faces, magnetic patch 8 is arranged on the spool 4, offer the fuel feed hole 10 that is communicated with oil filter on the housing 1,11, fuel feed hole 10,11 lead to two chambers that spool 4 is divided into respectively and are communicated with oil circuit before and after filtering in the oil filter respectively, the other end at housing 1 is provided with eye-viewing signalling body, eye-viewing signalling body comprises the carrier 2 that is installed on the housing, be associated with tinting of magnetic patch 3 and show knob 13, near 4 one settings of spool at this position and the magnetic patch 3 different in nature magnetic patch 5 of adhesive mutually, tint and show that knob 13 is located at the outer end, which is provided with the outer spring 6 that suppresses, stage clip 6 makes to tint and shows the outer all the time bullet of knob.Microswitch 7 in this example is directly installed connector socket 12, like this when oil filter is not comtaminated, call-sending cavity inner spool 4 both sides oil pressure are identical, spool 4 moves to right under stage clip 9 effects, magnetic patch 5 overcomes stage clip 6 elastic force and holds magnetic patch 3, making tints shows the not outer bullet of knob 4, simultaneously, magnetic patch 8 is separated by far away with microswitch 7 and can not the adhesive sender, stop up fuel feed hole 10 when oil filter is contaminated to a Room degree, the elastic force that oil pressure difference before and after 11 filtrations that produce will overcome stage clip 9 moves to left spool, magnetic patch 8 adhesive microswitches 7 action senders, simultaneously because magnetic patch 5 reduces away from magnetic patch 3 suction, tinting shows bullet outside knob 13 is under stage clip 6 effects.
The utility model is owing to have electric sender and order simultaneously and show function, makes stable performance, and is safe and reliable, and compact conformation, is a kind of desirable oil filter pollition warning system.
Claims (1)
1, a kind of differential oil strain signalling generator with housing, establish call-sending cavity in the housing, housing one end is provided with microswitch, being positioned at the microswitch side in the call-sending cavity is provided with by magnetic patch, the sender mechanism that spool and stage clip constitute, offer the fuel feed hole that is communicated with oil filter on the housing, of the present utility model being characterised in that: the other end at housing (1) is provided with eye-viewing signalling body, eye-viewing signalling body comprises the carrier (2) that is installed on the housing, be associated with tinting of magnetic patch (3) and show knob (13), near (4) settings of spool at this position and magnetic patch (3) the different in nature magnetic patch (5) of adhesive mutually, tinting shows that knob (13) is provided with and suppresses spring (6) outward.
