Abstract
The utility model discloses an impurity backflow resistant pipeline filter which comprises a pipe body with openings at two ends, wherein a filter pipe intersected with the pipe body in an inclined manner is communicated with the middle part of the pipe body; a cylindrical filter net is stuck in the filter pipe along the inner wall; the pipe body is divided into an upper section and a lower section by the cylindrical filter net; the upper section of the pipe body is communicated with an empty cavity of the cylindrical filter net and is communicated with the lower section of the pipe body through the cylindrical filter net; a funnel type filter net blocking cover for preventing back flowing of impurities is arranged in the cylindrical filter net in the radial direction; a sealing cover is arranged at the end part of the filter pipe; and the sealing cover is capable of tightly clamping the cylindrical filter net in the filter pipe. The impurity backflow resistant pipeline filter disclosed by the utility model has the advantages of being simple in structure, convenient to use, good in filtering effect and long in service life; the filter is unnecessary to detach in the event of replacing or cleaning the filter net; the impurity backflow phenomenon is prevented; and the safety of production and living water is ensured.
Description
Technical field
The utility model relates to a kind of filter, is specially the piping filter that a kind of anti-impurity refluxes.
Background technology
Water pipe is water delivery instrument important in the productive life, and in use, owing to be mingled with sometimes foreign matter and other device of easy obstruction and cross current in the water of carrying, makes troubles to productive life.Therefore disclosed a kind of filter that is installed on the water pipe in the prior art, so that water is filtered, with the device of protection with cross current.Yet existing water pipe refluxes easily with the impurity that filter filters out, and filter screen damages easily or stops up after long-time the use, needs to change filter or take off filter and change or clean filter screen, and it is convenient not therefore to change operation, affects the user and uses.
Description
The purpose of this utility model provides the piping filter that a kind of anti-impurity refluxes, reflux easily to solve the impurity that traditional filter filters out in the prior art, filter screen damages easily or stops up after long-time the use, need to change filter or take off filter and change or clean filter screen, it is convenient not to change operation, affects the problem that the user uses.
For achieving the above object, the technical solution adopted in the utility model is:
The piping filter that a kind of anti-impurity refluxes, it is characterized in that: the body that includes both ends open, described body middle part is communicated with the chimney filter that tilts to intersect with body, be fitted with the tubular filter screen along inwall in the described chimney filter, described tubular filter screen is divided into upper and lower two sections with body, described body epimere is communicated with the cavity of tubular filter screen, and be communicated with the body hypomere by the tubular filter screen, radially be provided with to prevent the funnel-form filter screen door of impurity backflow in the described tubular filter screen, the end of described chimney filter is provided with seal cover and seal cover can be clamped on the tubular filter screen in the chimney filter.
The piping filter that described a kind of anti-impurity refluxes is characterized in that: be provided with rubber seal between the end of described chimney filter and the seal cover.
The piping filter that described a kind of anti-impurity refluxes, it is characterized in that: described body both ends open inwall is equipped with screw thread.
The beneficial effects of the utility model are:
The utility model is simple in structure, easy to use, employing is fitted in chimney filter the design of tubular filter screen is set, when filter screen occurs to stop up or damage, when needing replacing or cleaning, only need the seal cover of chimney filter end is opened, extract filter screen blocked or that damage out, to clean or to change, will not pull down by filter, therefore change easy to operate, and adopt the design that funnel-form filter screen door is set in the tubular filter screen, effectively prevented the phenomenon that impurity refluxes, good filtration effect, long service life has guaranteed the security of productive life water.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the piping filter that a kind of anti-impurity refluxes, include the body 1 of both ends open, body 1 middle part is communicated with the chimney filter 2 that tilts to intersect with body 1, chimney filter 2 is interior to be fitted with tubular filter screen 3 along inwall, tubular filter screen 3 is divided into upper and lower two section 4,5 with body 1, body 1 epimere 4 is communicated with the cavity of tubular filter screen 3, and be communicated with body 1 hypomere 5 by tubular filter screen 3, radially be provided with to prevent the funnel-form filter screen door 6 of impurity backflow in the tubular filter screen 3, the end of chimney filter 2 is provided with seal cover 7 and seal cover 7 can be clamped on tubular filter screen 3 in the chimney filter 2.Be provided with rubber seal 8 between the end of chimney filter 2 and the seal cover 7, body 1 both ends open inwall is equipped with screw thread.
