Description

Valve block integrated dilute oil lubrication station filter

Technical field

It the utility model is related to a kind of filter, and in particular to a kind of valve block integrated dilute oil lubrication station filter.

Background technology

Dilute oil lubrication station is mainly used in the lubricating system of the plant equipment such as metallurgy, mine, cement, in order to improve lubricating oil Cleannes, edge type fine filter is housed in oil pump out of the mouth.Filter is connected in oil circuit by seamless steel pipe, due to using Bite type connects easy oil leak, and defect is more, therefore, welded type, the connection of steel-pipe welding formula is generally used in actual design production Problems be present：Because pipeline fitted position is difficult to determine, it is necessary to carry out including under pipe arrangement with weldering, whole process in assembling Material, spot welding trial assembly, dismounting welding, cleaning assembling, pressure testing detection etc., cause process very long, low production efficiency, it is difficult to realize standard Change, large-scale production；Meanwhile carry out causing environmental pollution serious with weldering, polishing, noise and dirt slag on assembly line, work is protected Shield is severely impacted.

In order to solve the problems, such as the easy oil leak in the junction of filter and steel pipe, it is proposed that the improvement of integrally disposed filter Scheme, such as a kind of compact connection filter valve block that patent 201520057197.2 is protected, by the way that filter is connected Connect and be installed on valve block, so as to avoid filter from directly being docked with oil circuit steel pipe, solve Leakage to a certain extent.But by Single line oil duct is used in its valve block, when oil duct blocks, then can only dismount processing, causes the valve block to need frequently dismounting Cleaning, functional reliability are low.

The content of the invention

The utility model is low in order to solve the problems, such as the easy oil leak in filter junction, functional reliability, while reduces peace Space is filled, makes filter dismounting more convenient, and then provide a kind of valve block integrated dilute oil lubrication station filter.

The utility model adopts the following technical scheme that：

A kind of valve block integrated dilute oil lubrication station filter, including valve block and filter, the valve block is interior to be provided with a worry Oil duct and some worry front oil ducts afterwards, be provided with valve block with consider after the oil-out, one-to-one with worry front oil duct that penetrates of oil duct The oil inlet of some external oil pumps, the oil inlet of filter penetrate with considering front oil duct, and oil duct passes through after the oil-out of filter and filter It is logical；Between worry front oil duct independently of each other, check valve is separately installed with each worry front oil duct, the oil-control that valve block is provided with check valve is led to Road.

Pressure difference hair flood device is installed, two pressure difference signal inputs of hair flood device connect entering for filter respectively in the valve block Hydraulic fluid port and oil-out, send out the external host computer of signal output part of flood device.

Overflow valve is additionally provided with the valve block and controls oily passage, overflow valve mounting hole and overflow valve oil return opening, overflow valve returns Hydraulic fluid port penetrates with the worry front oil duct in valve block.

The filter（3）For the filter of the model of ZU-A160 × 20.

The utility model has the advantages that：

1st, the filter integrated by valve block substantially reduces installing space, and connection and reasonable arrangement is compact-sized, is easy to user to adjust Examination, while the possibility of oil leak is reduced, reduce failure；

2nd, the filter integrated by valve block reduces assembly process, reduces labor intensity, improves production efficiency；

3rd, oil inlet passage before the filter no less than two is provided with valve block, can effectively solve because an oil duct block caused it is whole The non-serviceable problem of body device, improve the use reliability of filter；

4th, overflow ducts are provided with valve block, when there is plugged filter alarm, after can control overflow, then demolition and maintenance Filter, while overflow valve can prevent plugged filter from causing lubricating system hypertonia, serve the effect of safety valve.

Embodiment

With reference to accompanying drawing, specific embodiment of the present utility model is described further：

The outer of valve block integrated dilute oil lubrication station filter described in the utility model regards structure as shown in Figure 1, 2, including valve Block 2, check valve 4, overflow valve 5, filter 4 and the part of hair flood device more than 1.

The internal structure of valve block as viewed in figures 5-8, is provided with some oil-control passages, filter 3 is installed in valve block in valve block Disengaging oil return line in, wherein, is provided with two filter advance oil return lines in parallel, the oil inlet 1 and filter of valve block in valve block The UNICOM of oil inlet 1 forms a filter advance oil return line, and oil inlet 2 34 and the UNICOM of filter oil inlet 2 31 of valve block are formed Another filter advance oil return line, filters in advance oil return lines for two and is separately installed with check valve 4, prevents because oil return damages oil pump.Together When, pressure difference hair flood device 3 is also equipped with valve block, two pressure difference signal inputs of hair flood device 3 connect the oil-feed of filter respectively Mouth end and oil-out end, the external host computer of signal output part of flood device is sent out, it is upward by sending out flood device when filter blocks Position machine control system sends alarm signal, cut-out oil pump feed loop.

Overflow valve is additionally provided with the valve block and controls oily passage 38, overflow valve mounting hole 39 and overflow valve oil return opening 40, is overflow Valve oil return opening 40 is flowed to penetrate with oil inlet passage before the worry in valve block.When there is plugged filter alarm, after can control overflow, then Demolition and maintenance filter, prevent plugged filter from causing lubricating system hypertonia, play safety effect.

The filter operation principle：The oil that oil pump pumps out is by two oil-feeds inside valve block by entering through check valve Filter, the oil plant equipment that the oil-out through valve block lubricates into needs again after being filtered.In the course of work, flood is sent out The real-time monitor filter of device enters the pressure difference signal of oil outlet end, when filter blocks, sends alarm signal and timely in time Pressure release.

Wherein, the valve components such as overflow valve, filter, check valve and signalling generator are prior art, people in the art Member can use according to type selecting is actually needed, but the specific type selecting of element does not influence installation and connection of each element on valve body and closed System, therefore, the type selecting of valve components nor affect on the application's using understanding of the those skilled in the art to this programme is not influenceed Rights protection scope.
