Abstract
The invention provides a kind of filter core, comprise end cover of filter element, central tube and valve seat, described end cover of filter element abuts with central tube, described valve seat is installed on central tube, described end cover of filter element is plane towards the end face of central tube one end, and described valve seat is positioned at central tube one end towards end cover of filter element, and described valve seat and central tube are structure as a whole, described valve seat has valve seat through-hole, and described end cover of filter element has the end cover of filter element hole be communicated with valve seat through-hole.The present invention can avoid end cap in heating process, and valve seat is out of shape because toasting, and guarantees the assembly quality of valve seat and spool, thus ensures the filter effect of filter core.
Description
Technical field
The present invention relates to the filter element that a kind of spool valve seat assembly structure improves.
Background technology
Traditional filter cartridge construction overwhelming majority is: valve seat and end cap 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 major drawbacks of this structure is: filter core is in welding production process, end cap needs heated baking, boss due to valve seat is in the side of end cap and filter paper welding, and when heated baking, valve seat is easily out of shape, thus 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, and avoid end cap in heating process, valve seat is out of shape because toasting, and guarantees the assembly quality of valve seat and spool, thus 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 abuts with central tube, and 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 be 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 the same 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 the side deviating 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 the inside of seat design in 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 when heated baking, and valve core base would not be baked.
Accompanying drawing explanation
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 is for plane and this end welding has filter paper, central tube 2 is located at filter paper centre and is fitted with end cover of filter element 1, can for abutting or being fixedly connected with or welding or welding etc., the sidewall of central tube 2 is the cylinder-like structure be made up of some vertical muscle 22 and some horizontal bars 23, central tube 2 one end is through hole, the other end (one end be namely connected with end cover of filter element 1) is closed, 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 and central tube 2 are structure as a whole, valve seat 3 is a round platform with 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 face, valve seat through-hole 31 inward flange is 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 be communicated with valve seat through-hole 31, end cover of filter element hole 12 cross section is circle, from top to down, the cross-sectional area in end cover of filter element hole 12 reduces gradually, seamlessly transit between end cover of filter element hole 12 bottom hole wall and this end valve block hole 31 hole wall, central tube 2 has two bulge loops 21 towards one end of end cover of filter element 1, the central shaft of bulge loop 21 and the central shaft of central tube 2 on the same line, the object that bulge loop 21 is set be against end cover of filter element 1 end face 11 on 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 top is positioned at the side deviating from end cover of filter element hole 12 to be had cambered outwards protruding 25, lug 24 top and is positioned at and tilts to the direction away from end cover of filter element hole 12 gradually from bottom to top towards a side wall surface 26 in end cover of filter element hole 12, and the part of outside wall surface between protruding 25 and end cover of filter element 1 of lug 24 is vertical plane.End cover of filter element is compared with conventional bowl end cap, eliminate valve seat boss, end cover structure is simpler, end cap is when heated baking, there is not the phenomenon that valve seat is baked, can effectively avoid end cap in heating process, valve seat be out of shape because toasting, guarantee the assembly quality of valve seat and spool, thus ensure the filter effect of filter core; And end cover of filter element and other mechanisms are more convenient when assembling.
