Abstract

The utility model relates to a precision filter which is composed of at least two tubular elements, wherein the side surface of the upper end of any tubular element and the lower end of any tubular element are respectively provided with a connecting opening, and the tubular elements are communicated in sequence with each other by the connecting openings; a filter core is arranged in any tubular element; the upper end surface of any tubular element is provided with a closing cap, wherein the connecting opening of the first tubular element is connected with a water inlet pipe and a pressure meter is arranged in the water inlet pipe. The tubular elements are all arranged in a container, the water inlet pipe passes through the lateral wall of the container and the pressure meter is fixed to the outer wall of the container. The utility model carries out the dynamic detection of water pressure variation in the filter by setting the pressure meter in a water inlet opening; when the pressure meter shows that the water pressure is increased, staying solid suspended matter in a filter cartridge is increased; when the pressure meter shows the water pressure is in a set value, the filter core is on a replacing occasion. The utility model with convenient operation provides a visual and accurate basis to judge the replacing occasion of the filter core.

Description

Accurate filter
Technical field:
The utility model relates to water treatment facilities, relates in particular to water filter, particularly a kind of accurate filter.
Background technology:
In the prior art, organic matter, chloride are fallen in the solid suspension and the absorption that generally utilize filter to cooperate filter core to remove in the water.In the filter in the prior art, water by water inlet enter, with certain flow velocity successively by a plurality of filter cores, the water that obtains handling well from delivery port at last, solid suspension is then stayed in the filter core, filter core needs to change after using a period of time.Be the service time according to filter core the opportunity of judging the filter core replacing in the prior art, still, if the flow velocity of water is bigger in the processing procedure, then is difficult to judge the replacing opportunity of filter core, causes filter core to use later stage water quality uncontrollable.
Summary of the invention:
Technical problem of the prior art to be solved in the utility model is: because in the filter in the prior art, water is entered, is passed through a plurality of filter cores successively with certain flow velocity by water inlet, the water that obtains handling well from delivery port at last, solid suspension is then stayed in the filter core, and filter core needs to change after using a period of time.Be the service time according to filter core the opportunity of judging the filter core replacing in the prior art, still, if the flow of water is bigger in the processing procedure, then is difficult to judge the replacing opportunity of filter core, causes filter core to use later stage water quality uncontrollable.
The utility model is that the technical scheme that solution above-mentioned technical problem of the prior art is adopted provides a kind of accurate filter, described this accurate filter is made of at least two tubular elements, wherein, the upper side of any one described tubular element and lower end are provided with a connector respectively, described tubular element is communicated with by its connector order successively, be provided with filter core in any one described tubular element, the upper surface of any one described tubular element is provided with capping, wherein first tubular element connector is connected with a water inlet pipe, is provided with a Pressure gauge in described water inlet pipe.
Further, described tubular element all is arranged in the container, and described water inlet pipe passes the sidewall of described container, and described Pressure gauge is fixed on the outer wall of described container.
Further, the upper end of described container is provided with a container cover.
The utility model and prior art contrast, and its effect is actively with tangible.The utility model comes variation in water pressure in the detection of dynamic filter by Pressure gauge is set at water inlet, when Pressure gauge shows that hydraulic pressure increases, show that solid suspension stops increase in the filter core, when Pressure gauge shows hydraulic pressure to setting value, i.e. the replacing opportunity of filter core has been arrived in prompting.The utility model uses very convenient for the replacing of judging filter core provides visual and accurate foundation opportunity.
Description of drawings:
Fig. 1 is the structural representation of accurate filter of the present utility model.
The specific embodiment:
As shown in Figure 1, accurate filter of the present utility model, constitute by at least two tubular elements 2, wherein, the upper side of any one described tubular element 2 and lower end are provided with a connector respectively, described tubular element 2 is communicated with by its connector order successively, be provided with filter core in any one described tubular element 2, the upper surface of any one described tubular element 2 is provided with capping, wherein first tubular element connector is connected with a water inlet pipe 3, is provided with a Pressure gauge 5 in described water inlet pipe 3.
In a preferred embodiment of the present utility model, described tubular element 2 all is arranged in the container 1, and described water inlet pipe 3 passes the sidewall of described container 1, and described Pressure gauge 5 is fixed on the outer wall of described container 1.Also be provided with an outlet pipe 4 on the outer wall of described container 1, described outlet pipe 4 is connected with last tubular element.
The upper end of described container 1 is provided with a container cover 6.

Claims (3)

1, a kind of accurate filter, constitute by at least two tubular elements, it is characterized in that: the upper side of any one described tubular element and lower end are provided with a connector respectively, described tubular element is communicated with by its connector order successively, be provided with filter core in any one described tubular element, the upper surface of any one described tubular element is provided with capping, wherein first tubular element connector is connected with a water inlet pipe, is provided with a Pressure gauge in described water inlet pipe.
