Abstract
The utility model discloses the improvement of a differential pressure filter, which comprises a filter element (3), a filter head (4) and a filter case (2), wherein a differential pressure indicator (1) is arranged at an oil passage of the filter head (4). As the utility model arranges the differential pressure indicator at the filter head of the differential pressure filter, the differential pressure filter is capable of knowing the pressure value in an oil pipe in real time, so as to adjust the pressure and ensure the normal running of other workpieces. The utility model, compared with the prior art, has essential characteristic and progress.
Description
Technical field:
The utility model relates to a kind of improvement invention of differential filter device, what be specifically related to is a kind of improvement invention that the filter of pressure difference indicator is set on the differential filter device.
Background technology:
In the prior art, the differential filter device can be directly installed on return line system pipeline or external, is specially adapted to commercial Application, as rolling mill, injection machine, ironmaking equipment, paper machine, lubricating system etc., but the differential filter device of this kind structure all is not provided with pressure difference indicator, therefore, the pressure in the oil pipe is difficult to grasp, and brings inconvenience to the user.
Summary of the invention:
Given this, the technical problem that the utility model solved is for a kind of a kind of differential filter device that can know the oil circuit internal pressure is provided. in order to reach above-mentioned technique effect, the utility model adopts following technical scheme to realize: this kind differential filter device, include filter core, filter and filter housing is characterized in that the oily passage place of described filter is provided with pressure difference indicator.
As preferably: described differential filter device is the electrodynamic type pressure difference indicator.
As preferably: described differential filter device is visual hand pressure difference indicator.
Described filter housing is provided with a dismountable loam cake.
Be provided with a by-passing valve in the described filter housing.
The utility model is owing to be provided with pressure difference indicator at the filter place of differential filter device, therefore, the differential filter device can be real-time know force value in the oil pipe, thereby pressure is adjusted. to guarantee the normal operation of other workpiece. the utlity model has following advantage:
1, be provided with by-passing valve, when the filter core contamination and plugging, when pressure reduction surpassed certain setting value, by-passing valve was opened, and guarantees pipe safety.
2, be provided with pressure difference indicator, when the filter core contamination and plugging when the inlet outlet pressure differential value is the signalling generator setting, signal indicator sends signal, this moment the prompting changing filter core.
3, more renew cartridge is convenient, and the user can open more renew cartridge of loam cake according to installing space, also can pull down filter housing, drains the oil earlier from the lower end, to the following filter core that takes off.
4, easy for installation, but can install according to customer requirements difference angie type and through type
Description of drawings:
The utility model has following accompanying drawing:
Fig. 1 the utility model structural representation;
Fig. 2 is the utility model inside configuration vertical view;
Fig. 3 is the utility model indicator structure schematic diagram.
The specific embodiment:
Relevant detailed description of the present utility model and technology contents, conjunction with figs. is described as follows, however accompanying drawing is only for reference and explanation, is not to be used for the utility model is limited.
Differential filter device as shown in Figure 1, include filter core 3, filter 4 and filter housing 2, the oily passage place of described filter 4 is provided with electrodynamic type pressure difference indicator 1, also can be visual hand pressure difference indicator 1, described pressure difference indicator has plug screw 5, indicating device, piston element, and described piston element has piston 7, first magnet steel 8, first spring 9, door 10, and described indicating device has baffle plate 11, second spring 12, second magnet steel 13, indicator 14.When pressure reduction reached certain setup parameter before and after the filter, piston 7 overcame magnetic force, broke away from indicator 14 under the effect of spring force, and indicator 14 ejects under the spring force effect simultaneously, protrudes baffle plate 11.Described by-passing valve 15 has spring, adjustment screw, pressing plate, valve seat.When pressure reduction surpasses setting pressure before and after filter, the valve releasing pressure automatically.This can dispose voluntarily according to user's needs. be equipped with sealing ring at each contact place, in case stopping leak leaks.
But the above only is a preferable possible embodiments of the present utility model, is not in order to limiting to claim of the present utility model, and the equivalent structure that all utilization the utility model specifications and accompanying drawing content are done changes, and all in like manner is included in the scope of the present utility model.
