Abstract

The utility model relates to a Y-shaped filter, which belongs to the technical field of filtrating equipment. The filter comprises a Y-shaped body with one end fixed with an end cover; a barrel-shaped filter element is mounted in the body; a reducing hoop is sleeved on one end of the filter element; the excircle of the small end of the reducing hoop is inserted between the body and a runner matched with the body through a seal ring; the runner is provided with a runner front edge clung to the end surface of the circular bead of the reducing hoop (the front edge is made of wear resistant material); and the other end of the filter element is close to the end cover, is covered by a filter element pressure plate, and is pressed and fixed on a positioning ring inside the body through the filter element pressure plate. The utility model changes the seal-less connection between a traditional filter element and the body of the filter into seal connection, and a front edge structure is arranged on the contact surface between the reducing hoop of the filter element and the body. Therefore, water channeling between the filter element and the body of the filter can be effectively prevented for a long time; and meanwhile, in the utility model, the traditional end cover is no longer directly pressed on the filter element but rather positioned and fixed by virtue of the filter element pressure plate, and the damage of the filter element caused by the pressing of the end cover can be avoided.

Description

A kind of y-type filter

Technical field

The utility model relates to a kind of filter, and especially a kind of y-type filter belongs to the filtration facility technical field.

Background technology

Understand according to the applicant, each big metallurgy industry and heavy the manufacturing in the processing enterprise, used many water systems that comprise water filter at present, its pressure is between the 3bar-350bar, especially in the descaling system of smelter, used a large amount of water under high pressure filters.These structure of filter are all fairly simple, with the not too big difference of low-pressure water structure of filter, all are y-type filter (referring to Fig. 1) usually, and the candle filter end cap is fixed in the filter body, and do not have sealing between filter body.Because water under high pressure is bigger to the impulsive force of filter core, so scurry water through regular meeting between filter core and filter body.In addition, High-Pressure Water washes away for a long time filter core and causes the filter core excessive wear to be lost efficacy easily, the often deformation failure owing to the extruding of outer end cap of filter core simultaneously.This type of filter all uses on the key equipment of production line in the metallurgy industry, in case filter failure will cause whole production line to stop production, has caused unnecessary economic loss.

The utility model content

The purpose of this utility model is: the shortcoming at above-mentioned prior art exists proposes a kind of y-type filter that can keep filter effect for a long time.

In order to reach above purpose, y-type filter of the present utility model comprises the fixedly Y shape body of end cap of an end, in the described Y shape body tubular element is housed; One end suit undergauge hoop of described filter core, the small end cylindrical of described undergauge hoop is inserted in the runner mouth that described Y shape body matches with it by sealing ring, and described runner mouth has the runner seam of being close to described undergauge hoop shoulder end face; The contiguous end cap of the other end end of described filter core be stamped the filter core pressing plate, and the securing member of the filter core pressing plate that wore long presses solidly on the intrinsic locating ring of Y shape.

The utility model is tightly connected traditional filter core and the nothing between the filter body and has changed band into and be tightly connected, and on the contact-making surface of filter core undergauge hoop and body, be provided with fixing structure, therefore can permanently effectively prevent the water of scurrying between filter core and filter body; The utility model also directly is pressed in traditional end cap to change on the filter core by the filter core pressing plate and positions and fix simultaneously, has avoided filter core to be damaged by end cap crimp.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the structural representation of existing y-type filter.

Fig. 2 is the structural representation of an embodiment of the utility model.

Among the figure: Y shape body 1; O RunddichtringO 2; The runner seam 3 that the build-up wear-resistant material forms; Filter core 4; O RunddichtringO 5; O RunddichtringO 6; Filter core pressing plate 7; End cap 8; Locating ring 9; 10 undergauge hoops.

The specific embodiment

Embodiment one

The y-type filter of present embodiment as shown in Figure 2, the lower end of Y shape body 1 is end cap 8 fixedly, this end cap and body applying end face are equipped with O RunddichtringO 6, and this end cap 8 has the bulge loop that inserts body runner hole, between the cylindrical of this bulge loop and the body runner hole O RunddichtringO 5 is housed, form reliable hermetically-sealed construction, can prevent that fluid media (medium) from leaking.In the Y shape body 1 tubular element 4 is housed.One end suit undergauge hoop 10 of filter core 4, the small end cylindrical of this undergauge hoop is inserted in the runner mouth that Y shape body 1 matches with it by O-ring seals 2, the high-abrasive material of this runner mouth built-up welding, form the runner seam of being close to undergauge hoop 10 shoulder end faces 3, therefore can prevent effectively that unfiltered fluid media (medium) from not entering filter chamber by filter core 4, and after the seal failure of filter core, when the filtration fluid media (medium) flows through between filter core and body, also be difficult for filter core is washed away damage.Be welded with locating ring 9 in the runner of Y shape body 1 contiguous end cap 8.The contiguous end cap 8 of the other end end of filter core 4, end cap has filter core pressing plate 7, and the fastening bolt of the filter core pressing plate periphery that wore long presses solidly on the intrinsic locating ring 9 of Y shape.Like this, the end cap of filter no longer directly contacts with filter core, has avoided end cap that filter core 4 crimps are damaged, thereby has prolonged the service life of filter core.

Facts have proved that present embodiment has following beneficial effect: (1) has fundamentally solved filter core and has been washed away by pressure fluid and cause the problem that lost efficacy in advance, has guaranteed the service life of filter core; (2) avoided filter core in body, to be lost efficacy by end cap crimp; (3) eliminated because the unreasonable filter body that causes of hermetically-sealed construction leaks; (4) filter core is easier for installation, time saving and energy saving.

In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
