Abstract
Description
Technical Field
[0001] The utility model relates to the field of filters, in particular to a magnetic filter with a valve. Background Art
[0002] The existing Y-type filter is inconvenient to clean the filter screen. It is necessary to add a shut-off valve at each end of the filter. When the filter screen needs to be cleaned, the shut-off valve must be closed, and then a large wrench must be used to unscrew the valve cover of the filter to remove the filter screen for cleaning. After cleaning, the valve cover must be installed again and the wrench must be used to screw on the valve cover. Since the valve cover and the valve body are mostly sealed with polytetrafluoroethylene, repeated tightening and loosening may easily cause sealing failure and water leakage, and the entire cleaning process requires professional personnel to operate, which is not possible for ordinary family members. If no shut-off valves are installed at both ends of the filter, it will become very difficult to clean the filter. A lot of water must be drained when cleaning the filter. After cleaning the filter screen, water must be added to discharge the air in the water. The operation time is long and the cost is high.
[0003] In the wall-mounted boiler heating system, impurities in the water will accelerate the clogging of the wall-mounted boiler, heat exchanger, detection device and other equipment, which will continuously reduce the working efficiency of the equipment. Once the equipment is blocked, the loss is large. The conventional Y-type filter can only filter out particulate impurities, while magnetic impurities such as rust and iron ions are difficult to remove.
[0004] In the wall-mounted boiler heating system, most of the pipes are pre-buried inside the wall and extend horizontally out of the wall, and most of the water supply and return pipe interfaces of the wall-mounted boilers are facing downward; there are many pipes under the wall-mounted boiler and the installation space is small. Conventional magnetic filters need to be connected to the water pipes in a vertical direction, which makes installation difficult and unsightly. Summary of the invention
[0005] The purpose of the utility model is to provide a magnetic filter with a valve to solve the problems mentioned in the background technology. To achieve the above purpose, the utility model provides the following technical solutions: a magnetic filter with a valve, including a valve body, a filter cover, and a magnet, a sewage outlet is provided on the lower side of the valve body, a water inlet is provided on the right side of the valve body, a water outlet is provided on the upper side of the valve body, a filter cover is connected to the left side of the valve body, a medium cavity inside the filter cover is connected to the inside of the valve body, a magnet sleeve is provided on the left side of the filter cover, and the magnet is inserted into the magnet sleeve.
[0006] A valve cavity is arranged inside the valve body, a three-channel valve core is installed inside the valve cavity, one end of the core shaft is connected to the valve core, and the other end of the core shaft passes through the valve body and is connected to the handle.
[0007] An isolation pipe is arranged inside the valve body to separate the water outlet and the valve cavity.
[0008] The water flow inlet is detachable.
[0009] A sealing ring is sleeved on the left side of the valve body, the filter cover is connected to the valve body, and the sealing ring realizes a sealed connection between the filter cover and the valve body.
[0010] The filter cover, filter housing and magnet sleeve are an integrated structure.
[0011] The magnet is a strong magnet, cylindrical in shape, and can be disassembled.
[0012] A handle is arranged on the top of the magnet.
[0013] The technical effects and advantages of the utility model are as follows: the utility model realizes opening of the water inlet and closing of the sewage outlet, or closing of the water inlet and opening of the sewage outlet through the built-in three-channel valve core, while the water outlet is separated from the valve cavity and kept normally open; there is no need to install a valve at the water inlet, and sewage can be discharged by turning the handle to close the water inlet and open the sewage outlet. If magnetic impurities are adsorbed on the magnet sleeve, the magnetic impurities can be removed by pulling out the handle to remove the magnet. The entire sewage discharge process does not require the use of any tools and can be operated by ordinary household users, which is convenient and quick; the utility model is easy to install horizontally in a small space.

[0025] The present invention is further described below in conjunction with specific drawings. In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense.

[0026] Example
[0027] like Figure 1-Figure 9 A horizontally installed magnetic filter with a valve is shown, comprising a valve body 1, a filter cover 10, and a magnet 4. A sewage outlet 5 is provided on the lower side of the valve body 1, a water inlet 3 is provided on the right side of the valve body 1, and a water outlet 2 is provided on the upper side of the valve body 1. The left side of the valve body 1 is connected to a filter cover 9, and the medium cavity 17 inside the filter cover 10 is connected to the inside of the valve body 1. A magnet sleeve 18 is provided on the left side of the filter cover 10, and the magnet 4 is inserted into the magnet sleeve 18.
[0028] A valve cavity 12 is provided inside the valve body 1 , a valve core 14 with three channels 15 is installed inside the valve cavity 12 , one end of the core shaft 8 is connected to the valve core 14 , and the other end of the core shaft 8 passes through the valve body 1 and is connected to the handle 6 .
[0029] Wherein, an isolation tube 13 is provided inside the valve body 1 to separate the water outlet 2 and the valve cavity 12 .
[0030] The water inlet 3 is detachable.
[0031] A sealing ring 16 is sleeved on the left side of the valve body 1 , and the filter cover 9 is connected to the valve body 1 . The sealing ring 16 realizes a sealed connection between the filter cover 9 and the valve body 1 .
[0032] Among them, the filter cover 9, the filter cover 10 and the magnet sleeve 18 are an integrated structure.
[0033] The magnet 4 is a strong magnet, cylindrical in shape, and can be disassembled.
[0034] A handle 11 is provided on the top of the magnet 4 .
[0035] The process flow and working principle of the utility model are as follows: the utility model is installed on the pipeline, when the handle 6 is rotated to the open state, the sewage outlet 5 is blocked, and the water on the right side enters the valve core 14 through the water inlet 3 and the three channels 15 in sequence, and then enters the medium cavity 17 inside the filter cover 10 from another channel of the three channels 15. The particle impurities in the water are precipitated in the medium cavity 17 due to the reduced flow rate, and the magnet 4 in the magnet sleeve 18 can absorb the magnetic impurities in the water. The water that has been filtered and the magnetic impurities are removed flows out through the water outlet 2, and the filtration and magnetic absorption are completed. Function attached; when the handle 6 is rotated to the closed state, the built-in valve core 14 of the filter changes direction to block the water inlet 3 and open the sewage outlet 5, which is equivalent to installing a cut-off valve outside the water inlet 3. At this time, water flows from the water outlet 2 to the medium cavity 17, enters the valve core 14 through the three channels 15, and then flows out from the sewage outlet 5 through another channel of the three channels 15. Particulate impurities are also discharged with the water flow. If there are magnetic impurities, pull out the handle 11 to take out the magnet 4, and the magnetic impurities adsorbed on the outside of the magnet sleeve 18 fall off and are discharged with the water flow, thereby removing the magnetic impurities.
[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
