The present disclosure relates to a filter, which comprises a housing, a protective bushing, a magnetic bar and a filter screen. The protective bushing, the magnetic bar and the filter screen are disposed in the housing. The protective bushing comprises a cavity and a channel. The channel is disposed along the axial direction of the cavity. The advantageous effects of the filter according to the present disclosure lies in that: the magnetic bar inside the filter can adsorb metal impurities in the water in the channel; and the channel is in S shape which can increase the length of the flow path of the water so that the metal impurities in the water can be guaranteed to be sufficiently adsorbed by the magnetic bar; and the filter screen can filter out non-metal impurities in the water. An exhaust valve provided at the top of the protective bushing can keep the balance between the air pressure inside the filter and the air pressure outside the filter, which can ensure that the water can flow out and in smoothly. The filter is attached with an operating handle. If the user wants to disassemble the filter to clear up the metal impurities and non-metal impurities in the filter, he can disassemble the filter by means of the operating handle without the need of professional operator, which is convenient and simple.

A strainer (101) for use in fluid piping. The strainer (101) comprises a body (102) for connection to a fluid piping inflow conduit (201) and to a fluid piping outflow conduit (202). The body (102) defines an interior chamber (103), a fluid inlet port (104) and a fluid outlet port (105). The body (102) defines a fluid flow path (106) between the fluid inlet port (104) and the fluid outlet port (105) that extends through the interior chamber (103). The strainer (101) comprises a screen collector (107) that is removably locatable in the body (102), within the fluid flow path (106). The strainer (101) further comprises a permanent magnet collector (102) that is removably locatable in the body (102). The strainer (101) may be used in fluid circuit piping of a heating or a cooling system.

Examples are disclosed herein that relate to an in-pond water quality maintenance system. One example provides a pond water quality maintenance system, including a skimmer basin configured to collect pond surface debris, the skimmer basin including an upper opening configured to permit a flow of water and debris from a pond surface into the skimmer basin, a strainer basket positioned within the skimmer basin and configured to trap at least some of the debris that enters the skimmer basin through the upper opening, a skimmer pump positioned within the skimmer basin below the strainer basket, the skimmer pump configured to draw water through the strainer basket and to pump the water out of the skimmer basin, and one or more lower openings configured to permit a flow of water into the skimmer basin from a pond depth below the strainer basket.

There is provided a removable downspout filter for installation into a downspout. The removable downspout filter includes a filter basket with attached face plate. The face plate includes side flaps configured to wrap around the downspout when the downspout filter is installed and is generally configured to blend in with the downspout. Also provided is a downspout with installed filter and kits including the same.

The present disclosure relates to a solenoid valve. The solenoid valve includes an armature provided inside the sleeve, a plunger configured to ascend and descend by the operation of the armature, an elastic member configured to press the plunger toward the armature, a magnet core having a through hole in which the plunger and the elastic member are provided and forming an inner space in a longitudinal direction, a valve seat provided in the inner space and on which an orifice penetrating in an axial direction is formed to be opened and closed by the plunger, and a plurality of flow resistance members each including a ring body interposed between the valve seat and the magnet core to generate a flow resistance of a braking fluid, and a slot formed at one side of the ring body to penetrate through the ring body so that the braking fluid passes therethrough.

A pipeline strainer having a body with a straining element therein. One or more magnets are removably inserted into the straining element and configured to be removed from the body without causing liquid within the cavity to drain from the pipeline strainer. A drywell is used to house the magnets. The movement of withdrawing the magnets pulls metal particles along the outer surface of the drywell toward a debris drain. A baffle is disposed at the end of the drywell that is adjacent or near the debris drain to reduce turbulence from the fluid flow within the pipeline strainer.

A planting structure includes a water filtering bag, a plurality of hanging ears mounted on an outer face of the water filtering bag, and a plurality of planting sources placed in the water filtering bag. The water filtering bag is made of permeable material with a permeation effect. The water filtering bag has an interior provided with a receiving space. The planting sources are received in the receiving space of the water filtering bag. Thus, the planting structure is directly hung on a cup by the hanging ears, so that the user plants and takes out the planting sources at any time according to the practical requirement.
