Abstract
Disclosed is a straight through filter, which relates to the filter device, in particular to a straight through filter used to filter the contamination impurity in the pipe lines. The straight through filter is provided with an upper housing, a lower housing, a filter element, a filter element framework, a filter net and a filter element contamination differential pressure gauge. A flange is arranged on the connecting point of the upper housing and the lower housing; the upper housing is provided with an outlet and an inlet, the inlet is communicated with the chamber of the lower housing, and the outlet is communicated with the top of the filter element; the filter element is arranged in the framework, the filter net is arranged out of the framework, and the filter net is arranged in the chamber of the lower housing; the bottom of the filter element is provided with a spring slot, the lower part of the lower housing is provided with a drain outlet, and the differential pressure gauge is arranged on the top. Arranging the outlet and the inlet on the upper part of the upper housing improves the quality of the fluid obviously. The automatic display of the differential pressure gauge is convenient for renew the filter element in time. The utility model has the advantages of large flow capacity, small resistance and long service life; the utility model also has the advantages that: the straight through filter is convenient to install, connect, clean and renew the filter element, and can be matched by standard flange; the filter element is not easy to be break by touching; the pipeline system is simplified. The straight through filter is especially suitable to be installed on the outlets of the oil pumps and the inlets which needs lubricating devices and hydraulic devices. And can effectively filter the contamination impurity.
Description
Technical field
The utility model relates to a kind of filter, and especially a kind of pipeline that is used for filters the through type filter that pollutes impurity.
Background technology
Usually in device systems such as oil pump, hydraulic test, rotating machinery, there are a lot of impurity that pollute, filtering is polluted impurity to the cleannes that improve the various device system with have crucial meaning service life, therefore in the oil pump exit or need the porch of the hydraulic test of lubricating utensil, all need to install filter usually.Existing filter pipeline equipment adopts multiple or multiple-piece filter core mostly, and wherein multi-joint bucket formula filter core in use occurs when pressure reduction is big through regular meeting, and multi-joint extrusion causes and has no idea to load and unload, cleans and scrap together.Filter bottom is located in the import of filter simultaneously, leans on very closely with sewage draining exit.
Summary of the invention
It is big that the utility model aims to provide a kind of flow, installs, cleaning makes things convenient for the through type filter of long service life with renew cartridge more.
The utility model is provided with lower house, filter core, frame of filter element, filter screen, filter core pollution pressure device, and last lower house is established lower flange respectively in the junction, and upper shell is established entrance and exit respectively, and inlet is communicated with lower housing cavity, and outlet is communicated with the top of filter core.Filter core is located in the frame of filter element, and filter screen is located at outside the frame of filter element, and filter screen is located at lower housing cavity, is provided with the bullet groove between filter core and the lower house bottom, and sewage draining exit is established in the bottom or the bottom of lower house, and filter core pollutes the top that pressure device is located at upper shell.
Owing to import and outlet all are located at the top of upper shell, so can obviously improve the quality of fluid.Because the pressurized central point at existing multi-joint filter core increases a center flange ring, strengthens the compression capability of filter core, and the filter core of large flow filter is adopted little rod type filter element, is used in combination.Pollute pressure device owing to be provided with filter core, when therefore the pressure reduction that stops up outlet and porch when the contaminated thing of filter core was 0.05MPA, filter core polluted pressure device demonstration automatically, so that timely renew cartridge more.The utility model is particularly useful for being installed in the oil pump exit or needs lubricating utensil and the porch of hydraulic test, the effective pollution impurity in the filtering pipeline, its effect is that flow is big, oil filling capacity is big, resistance is little, installation connects, clears up and more renew cartridge is convenient, its import and export can adopt tubular type (screw thread) or flange form to connect, can be directly supporting with standard flange, connect together with existing pipeline, needn't process flange and connection fittings more in addition.Filter core is difficult for breaking, long service life, and simplified system pipeline.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
As shown in Figure 1, the utility model is provided with upper shell 1, lower house 2, filter core 3, frame of filter element 4, filter screen 5, filter core pollution pressure device 6, last lower house 1,2 is established lower flange 11,21 respectively in the junction, upper shell 1 is established inlet 12 and outlet 13 respectively, inlet 12 is communicated with the inner chamber 22 of lower house 2, exports 13 and is communicated with the top of filter core 3.Upper shell 1 adopts slip with the top of filter core 3, and is added with the O circle.Filter core 3 is located in the frame of filter element 4, filter screen 5 is located at outside the frame of filter element 4, and filter screen 5 is located at lower housing cavity 22, is provided with between filter core 3 and the lower house bottom 23 and plays groove 7, sewage draining exit 8 is established in the bottom of lower house 2 or bottom, and filter core pollutes the top that pressure device 6 is located at upper shell 1.The filtering material of filter core adopts all-glass paper, and frame of filter element adopts stainless steel, and precision is 10 μ m, and flow is 74L/min.
Claims (4)
