Abstract
The invention provides a filter core. The filter core comprises a filter core end cover, a central pipe and a valve seat, wherein the filter core end cover abuts against the central pipe, the valve seat is installed on the central pipe, the end surface, facing the central pipe, of the filter core end cover is a plane, the valve seat is arranged on one end, facing the filter core end cover, of the central pipe, the valve seat and the central pipe are of an integrated structure, the valve seat is provided with a valve seat through hole, and the filter core end cover is provided with a filter core end cover hole which is communicated with the valve seat through hole. According to the filter core, in a heating process of the end cover, the valve seat can be prevented from deforming due to heating, the assembling quality of the valve seat and a valve core can be guaranteed, and the filter effect of the filter core can be further guaranteed.
Description
Technical field
The present invention relates to the improved filter element of a kind of spool valve seat assembly structure.
Background technology
Traditional filter cartridge construction overwhelming majority is: valve seat and end cap are as a whole, central tube is a hollow cylinder, its advantage is that injection mold structure is fairly simple, and production of plastics parts is relatively easy, but the main drawback of this structure is: filter core is in welding production process, end cap needs heated baking, due to the boss of the valve seat side in end cap and filter paper welding, in the time of heated baking, valve seat is easily out of shape, thereby affect the assembling of spool and valve seat, and then affect the filter effect of filter core.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of filter core, avoids end cap in heating process, and valve seat is out of shape because being subject to toasting, and guarantees the assembly quality of valve seat and spool, thereby ensures the filter effect of filter core.
For solving above-mentioned existing technical problem, the present invention adopts following scheme: a kind of filter core, comprise end cover of filter element, central tube and valve seat, described end cover of filter element and central tube butt, described valve seat is installed on central tube, and described end cover of filter element is plane towards the end face of central tube one end, described valve seat is positioned at central tube one end towards end cover of filter element, described valve seat and central tube are structure as a whole, and described valve seat has valve seat through-hole, and described end cover of filter element has the end cover of filter element hole being communicated with valve seat through-hole.
As preferably, described valve seat is a round platform, and described valve seat through-hole is positioned at the center of round platform and runs through the two ends up and down of round platform.
As preferably, described valve seat through-hole is circular hole.
As preferably, chamfering or round-corner transition between the internal face of described valve seat through-hole and valve seat bottom end face.
As preferably, one end that described central tube is connected with end cover of filter element has at least one bulge loop, and the central shaft of described bulge loop and the central shaft of central tube are on same straight line.
As preferably, described bulge loop is two.
As preferably, the sidewall of described central tube is made up of some vertical muscle and some horizontal bars.
As preferably, from top to down, the cross-sectional area in described end cover of filter element hole reduces gradually.
As preferably, the surrounding that the one side that described end cover of filter element deviates from central tube is positioned at end cover of filter element hole has some lugs, and described lug top is positioned at a side that deviates from end cover of filter element hole and has cambered outwards projection.
Beneficial effect:
A kind of filter core that the present invention adopts technique scheme to provide, by seat design in the inside of central tube blind end, as a whole with central tube, and the one side of end cover of filter element and filter paper welding is planar structure, like this, in production process, end cover of filter element is in the time of heated baking, and valve core base just can not be baked.
Brief description of the drawings
Fig. 1 is structure assembly drawing of the present invention;
Fig. 2 is the enlarged drawing at A place in Fig. 1.
Detailed description of the invention
As illustrated in fig. 1 and 2, a kind of filter core, comprise end cover of filter element 1, central tube 2 and valve seat 3, the end face 11 of end cover of filter element 1 one end has filter paper for plane and this end welding, central tube 2 is located in the middle of filter paper and is fitted with end cover of filter element 1, can or be fixedly connected with or welding or welding etc. for butt, the sidewall of central tube 2 is the cylinder-like structure being made up of some vertical muscle 22 and some horizontal bars 23, central tube 2 one end are through hole, the other end (one end being connected with end cover of filter element 1) sealing, blind end is fitted on end cover of filter element completely, valve seat 3 is installed on central tube 2, valve seat 3 is positioned at central tube 2 one end towards end cover of filter element 1, valve seat 3 is structure as a whole with central tube 2, valve seat 3 is one to have the round platform of valve seat through-hole 31, valve seat through-hole 31 is circular hole, valve seat through-hole 31 is in the center of round platform and runs through the two ends up and down of round platform, chamfering or round-corner transition between the internal face of valve seat through-hole 31 and valve seat 3 bottom end faces, valve seat through-hole 31 inward flanges are smooth circular arc, be convenient to assemble with spool, and good sealing effect, end cover of filter element 1 has the end cover of filter element hole 12 being communicated with valve seat through-hole 31, end cover of filter element hole 12 cross sections are circle, from top to down, the cross-sectional area in end cover of filter element hole 12 reduces gradually, between end cover of filter element hole 12 bottom hole walls and this end valve block hole 31 hole walls, seamlessly transit, central tube 2 has two bulge loops 21 towards one end of end cover of filter element 1, the central shaft of the central shaft of bulge loop 21 and central tube 2 is on same straight line, and the object that bulge loop 21 is set is to be against on the end face 11 of end cover of filter element 1, to ensure sealing, the surrounding that the one side that end cover of filter element 1 deviates from central tube 2 is positioned at end cover of filter element hole 12 has three lugs 24, lug 24 tops are positioned at a side that deviates from end cover of filter element hole 12 to be had cambered outwards protruding 25, lug 24 tops and is positioned at towards a side wall surface 26 in end cover of filter element hole 12 to tilt to the direction away from end cover of filter element hole 12 gradually from bottom to top, and the part of the outside wall surface of lug 24 between projection 25 and end cover of filter element 1 is vertical plane.End cover of filter element is compared with traditional end cover of filter element, remove valve seat boss, end cover structure is simpler, end cap is in the time of heated baking, the phenomenon that does not exist valve seat to be baked, can effectively avoid end cap in heating process, and valve seat is out of shape because being subject to toasting, guarantee the assembly quality of valve seat and spool, thereby ensure the filter effect of filter core; And more convenient when the assembling of end cover of filter element and other mechanisms.
