Abstract

The utility model relates to a filter capable of changing a filter element, which belongs to the field of the filter. The utility model aims at the filter element of the ordinary disposable filter, and the filter element can be changed. A linking cover (1) of the ordinary disposable filter is made into form a sealed detachable shape with a housing combined group (2) of the linking cover, and the linking cover and the housing combined group form a detachable screwing structure. The utility model has the advantages that the whole filter is not required to be changed during maintenance, and the filter element is just changed. Thus, a plurality of raw materials are saved, use cost is largly reduced, and the change of the filter element is convenient, stable and reliable.

Description

The filter-core changeable type rotary filter

Technical field

The utility model belongs to the cleaner field, relates to a kind of filter-core changeable type rotary filter.

Background technology

In motor vehicle and electromechanical equipment, great majority all need cleaner, its effect is to required relevant flow media: air, lubricating oil, cooling fluid, fuel etc. filter, to guarantee total system reliability of operation and high life, in cleaner, it is to adopt the rotation fitting type structure that quite a few liquid filter is arranged---be cleaner adopts screw-type to be connected with main body, concrete form is: filter core is fixed in the filter case, form incorporate globality structure, link together by the internal thread of media outlet and the filter block on the equipment during installation, its great advantage is to change conveniently, and during maintenance, one unloads (old) dress (newly) gets final product, weak point is: the disposable use of cleaner globality, can't be separately renew cartridge more, the use cost height causes the lot of materials waste.

Summary of the invention

The technical problem that solves: a kind of filter-core changeable type rotary filter is provided,, will change by whole cleaner during maintenance because its filter core is interchangeable, only more renew cartridge gets final product, and therefore, can save a large amount of raw material, significantly reduce use cost, and the filter core replacing is convenient, safe, reliable.

Technical scheme

The filter-core changeable type rotary filter, basic structure with common rotatable filter: have that medium is imported and exported and connection lid 1, shell that its outlet has an internal thread in conjunction with group 2, filter core in conjunction with group 3, end spring 4, for media security valve group 5, inside and outside sealing ring 6 and 7 etc., and connection cover 1 and is pressed on by inner seal ring 6 dismoutabilities in conjunction with group 3 with filter core, it is characterized in that: connection is covered 1 and is combined with shell and to organize 2 adjustable removable again mutual sealings and link together.

Beneficial effect: because its filter core is replaceable, will not change by whole cleaner during maintenance, only more renew cartridge gets final product, and therefore, can save a large amount of raw material, significantly reduces use cost, and the filter core replacing is convenient, safe, reliable.

Description of drawings

Accompanying drawing 1, general structure schematic diagram;

Accompanying drawing 2, connection are covered 1 structural representation;

Accompanying drawing 3, shell are in conjunction with another program structural representation of organizing 3;

The specific embodiment: further explanation in detail in conjunction with the accompanying drawings;

Shown in accompanying drawing 1,2: connection cover 1 outward flange inboard and is had round platform rank 8, has external screw thread 9 on its cylinder, its annular mark time 10 and intermediate seal circle 11 supporting; Shell is in conjunction with having function connector (13) in the group 2, shell 12 is interlocked with its tightening seal formula, function connector 13 has outer opening function trough 14, intermediate seal circle 11 is housed in it, below the upper inner of shell 12 and function connector 13, connecting ring 15 is housed fixedly, have internal thread 16 on this ring, and complement one another with external screw thread 9 that connection is covered on the cylinder on 1 round platform rank 8.

As shown in Figure 3: shell is following structure in conjunction with group 2: suitable for reading direct and connecting ring 15 sealings of shell 12 are fixed together, the outer face of connecting ring 15 has outer opening function trough 14, intermediate seal circle 11 is housed in it, have internal thread 16 on the connecting ring 15, and complement one another with external screw thread 9 that connection is covered on the cylinder on 1 round platform rank 8.

As shown in Figure 1: filter core comprises filter core 17 and inside and outside casing 18 and 19 in conjunction with in the group 3, makes up shape upper press cover 20 and lower cover 21 in addition, and lower cover 21 central authorities have for media security valve group 5.

The utility model said " filtration package " comprises following three kinds of situations:

The first, but globality more renew cartridge but do not comprise in conjunction with group 3 for media security valve group 5;

The second, but globality more renew cartridge comprise for media security valve group 5 in conjunction with group 3;

The 3rd, only more renew cartridge in conjunction with the filter core 17 in the group 3 and inside and outside casing 18 thereof and 19 and do not comprise other annexes.

Method of operating: when needs more during renew cartridge, integral body unloads cleaner, unloads connection then and cover 1, and taking out needs the old filter core changed, load onto new filter core after, refill to correlate and cover 1, be installed in again afterwards on the filter block of equipment and get final product.
