Description
Technical field
Synchronously alarmed the present invention relates to a kind of low pressure, bypass group indicater structure, suitable for that there need to be pollution to report simultaneously
Police is with bypass function but is limited in the system that can not be integrated and used by installing space.
Background technology
Existing indicator generally only possesses oily filter pollution alarm simple function, to realize the by-pass flow of fluid and also need installation only
Vertical by-passing valve is in system.Indicator and by-passing valve are independent functional module, are installed in parallel and are imported and exported in oily filter.For upper
State the product of functional requirement, because installing space is big needed for installation site, cause install housing it is complicated, process is various, it is difficult to
Processing.Indicator and by-passing valve are to work independently, it is impossible to ensure that the two is acted simultaneously.Itd is proposed for this kind of light and handy and save space
Achievable alarm, the synchronous low-pressure indicator device of bypass.
The content of the invention
The task of the present invention is to propose that one kind is swift in response, is compact-sized, and the collection of synchronous alarm and bypass function can be achieved
Into the synchronous alarm bypass group indicater structure of one kind for changing indicator structure design.
The task of the present invention, which is done in such a way that, is characterized in that：The technical program is by valve assembly and magnetic instruction group
Part is formed, and the valve assembly includes magnetic element and piston, and the magnetic instruction component includes upper magnetic element and protection
Set, the upper magnetic element and protective case are formed magnetic instruction component and are put the top of housing to refer to by gluing be connected together of normal temperature
Show chamber, protective cap is fixed composition closed chamber with fixed seat by sealing ring and isolated with ambient atmosphere, the magnetic element and work
Plug forms the bottom that valve assembly is seated in housing by gluing be connected together of normal temperature, is induction cavity；Valve assembly had both served as bypass
Valve valve can be used as the pressure element of indicator again；Little spring, big spring are assembled successively after upper and lower magnetic element is bonding,
Spring base, back-up ring are installed again, the instruction chamber and induction cavity form indicator.The indicator is formed for plug-in, is added on housing
Work has the screw hole being connected with hydraulic system, is screwed, and is installed in parallel by the mounting hole on system casing with filter core.Shell
Import, outlet and low pressure chamber pressure sensing hole are provided with body.
The present invention has the following effects that：It is product with compact structure, small volume, convenient for installation and maintenance, it is simultaneously emitted by alarm signal
With make fluid by-pass flow, system is played a protective role.
Brief description of the drawings
The structural representation of Fig. 1 present invention.
Drawing explanation：1st, protective cap, 2, fixed seat, 3, sealing ring, 4, upper magnetic element, 5, little spring, 6, housing, 7, enter
Mouthful, 8, magnetic element, 9, piston, 10, big spring, 11, spring base, 12, low pressure chamber pressure sensing hole, 13, back-up ring, 14, outlet,
15-17, sealing ring, 16, normal temperature glue, 17, sealing ring, 18, protective case.
Embodiment
The structure drives valve assembly movement to realize the switching function of fluid by hydraulic coupling.For integrated alarm function
It is integrated, magnetic element is provided with valve assembly, indicator structure is formed with the magnetic attracting indication piece of epicoele.Work as monitoring
When filter core is uncontaminated, upper and lower chamber magnetic element is attracting state, and indicator is not alarmed；As the working time extends, filter core is collected
Pollutant increase, for pressure difference when reaching alarm pressure, hydraulic coupling driving valve assembly, which moves down, makes fluid by-pass flow, together before filter, after filter
When two magnetic elements separate, epicoele magnetic element ejects alarm, realizes synchronizing function under the action of the spring.
Specific embodiment as shown in figure 1, the technical program by valve assembly and magnetic instruction component form, the valve group
Part includes magnetic element 8 and piston 9, and the magnetic instruction component includes upper magnetic element 4 and protective case 18, gluing by normal temperature
It is connected together.Structure is fixed in the top that the magnet assembly puts housing 6 for instruction chamber, protective cap 1 by sealing ring and fixed seat 2
Isolate into closed chamber with ambient atmosphere, this structure is to maintain instruction chamber and dried, and the magnetic element is with piston 9 by normal temperature glue
16 bond together, and the bottom that valve assembly is seated in housing is induction cavity, had not only served as by-passing valve valve but also can be used as indicator
Pressure element.Assemble little spring 5, big spring 10 successively after upper and lower magnetic element is bonding, then spring base 11, gear are installed
Circle 13.The instruction chamber and induction cavity form indicator.
Sealing ring 17 act as outside sealing, prevents fluid from leaking out to outside product and causes the accident.Sealing ring 15-17 is acted on
For product import and export fluid is isolated to establish pressure difference.
The indicator is formed for plug-in, and the screw hole being connected with hydraulic system is machined with housing, and by housing
The mounting hole in portion is installed in parallel with filter core to be screwed.Import 7, outlet 14 and low pressure chamber pressure sensing hole 12 are provided with housing,
Import 7 experiences the forward and backward pressure difference of filter core simultaneously with low pressure chamber pressure sensing hole 12.
As shown in figure 1, the technical scheme is that internal valve assembly is movement parts, group is indicated by magnetic attracting
Part.Instruction component can be driven to send alarm signal, the valve structure of by-passing valve is served as again, possess sealing, bypass function.Filter core
During normal work, valve assembly and magnetic instruction component rely on magnetic force into attracting state.With the extension of filter core working time, refer to
Show that device inlet and outlet experience the increase of filter core pressure difference.When filter core is blocked to alarm pressure, valve assembly overcomes acting force of the spring downward
It is mobile magnetic instruction component is disengaged suction and is ejected alarm, while synchronization action is realized in housing inlet and outlet connection, fluid by-pass flow.
After filter core is changed, protective cover hand-reset magnetic instruction component is opened, cancels alarm.Such a indicator structure working stability,
Reliably, it is swift in response.
