Description

Technical Field

[0001] The utility model belongs to the technical field of foot valve design, and particularly relates to a foot valve facilitating the disassembly of a net cover. Background Art

[0002] A foot valve generally refers to a check valve; a check valve is a valve in which the closing member is a circular valve flap and which blocks the reverse flow of the medium by its own weight and the action of the medium pressure.

[0003] The above-water foot valve is an upgraded product of the underwater foot valve. When acting as a foot valve, it can be installed on the water surface at the water inlet pipe. When acting as a check valve, it can be installed at the 90-degree bend at the outlet of the pump instead of an elbow.

[0004] At present, Chinese Patent with the publication number CN202031829U and the publication date of November 9, 2011 discloses a new type of above-water foot valve, which is composed of a valve plate, a rubber gasket, and a sealing flange. In the inner cavity at the connection between the sealing flange and the valve body, there are a rubber gasket and a valve plate; the valve rod passes through the fastening plate, the rubber gasket, and the valve plate from bottom to top, and the top is inserted into the inner cavity of the guide rod arranged in the center of the blank cover; a valve body upper flange is arranged at the upper end of the valve body, and a rubber gasket is arranged between the valve body upper flange and the blank cover, and is locked by bolts passing through the blank cover and the valve body upper flange.

[0005] Since the above-water foot valve is above the water surface, a suction pipe needs to be installed at the lower end of the foot valve, and the suction pipe is immersed below the water surface to draw water; at the same time, in order to prevent sundries in the water from entering the foot valve and blocking it, a net cover also needs to be arranged at the lower end of the suction pipe to filter the sundries in the water.

[0006] However, after the sundries are filtered by the net cover, they are likely to cover the surface of the net cover, which will cause the blockage of the net cover at this time, and finally affect the water pumping efficiency of the suction pipe. Content of the Utility Model

[0007] The purpose of the utility model is to provide a foot valve facilitating the disassembly of a net cover, which can clean the sundries attached to the surface of the net cover.

[0008] The above technical object of the utility model is achieved through the following technical solutions: A bottom valve facilitating the disassembly of a mesh cover, comprising a valve body, a valve cover arranged at the upper end of the valve body, a rod sleeve arranged in the middle of the valve cover, a valve rod with its upper end embedded in the rod sleeve, a pressing plate arranged at the lower end of the valve rod, a sealing gasket arranged on the lower surface of the pressing plate, a suction pipe arranged at the lower end of the valve body, and a mesh cover arranged at the lower end of the suction pipe. An iron sleeve is sleeved on the periphery of the mesh cover, and a brush hair layer abutting against the outer wall of the mesh cover is arranged on the inner wall of the periphery of the iron sleeve. A through hole penetrating the valve rod is opened at the center of the valve rod. A connecting rod is arranged in the valve body, with its upper end passing through the rod sleeve and its lower end passing through the through hole and entering the mesh cover. Connecting arms are arranged on both sides of the lower end of the connecting rod, and magnet blocks for attracting the iron sleeve are arranged at the ends of the connecting arms far away from the connecting rod.

[0009] A further setting of the utility model is that: a handle plate located above the valve rod is arranged at the upper end of the connecting rod.

[0010] A further setting of the utility model is that: a limiting plate with an outer diameter larger than that of the iron sleeve is arranged on the lower end surface of the mesh cover.

[0011] A further setting of the utility model is that: bumps are arranged at both sides of the lower end of the suction pipe, and card holes are opened in the bumps. Elastic arms in an L shape with their upper ends passing through the card holes are arranged on both sides of the upper end of the mesh cover, and a card head with a right-angled triangle cross-section for clamping on the upper surface of the bump is arranged at the upper end of the elastic arm.

[0012] A further setting of the utility model is that: a guiding inclined surface for abutting against the inclined surface of the card head is opened on the inner wall of the lower side of the card hole.

[0013] A further setting of the utility model is that: an embedding end embedded in the lower end of the suction pipe is arranged at the upper end of the mesh cover.

[0014] In summary, the utility model has the following beneficial effects:

[0015] 1. When the mesh cover is blocked, the operator holds the upper end of the connecting rod above the valve body, and then pulls the connecting rod up and down. At this time, the connecting rod can drive the connecting arms and the magnet blocks to move up and down in the mesh cover. Among them, the iron sleeve sleeved outside the mesh cover is attracted by the magnet blocks. At this time, the iron sleeve can move up and down with the magnet blocks under the suction of the magnet blocks. Then the iron sleeve can move up and down on the outer wall of the mesh cover. By using the brush hair layer arranged on the inner wall of the periphery of the iron sleeve and abutting against the outer wall of the mesh cover, the brush hair layer can clean the sundries attached to the outer wall of the mesh cover at this time. Finally, the sundries attached to the surface of the mesh cover can be cleaned more conveniently;

[0016] 2. By using the handle plate provided at the upper end of the connecting rod and located above the valve rod, the handle plate can be held by hand, which is conducive to driving the connecting rod to move up and down more conveniently;

[0017] 3. By using the limiting plate provided on the lower end face of the mesh cover and having an outer diameter larger than that of the iron sleeve, the limiting plate can play a role in limiting the iron sleeve sleeved on the outer wall of the mesh cover, preventing the iron sleeve from falling off from the lower end of the mesh cover;

[0018] 4. The upper end of the elastic arm of the mesh cover is embedded in the card hole on the convex block, and at the same time, the elastic arm uses the card head at the upper end to be clamped on the upper surface of the convex block. At this time, the rapid installation of the mesh cover at the lower end of the suction pipe can be realized; at the same time, when the mesh cover needs to be disassembled, the operator only needs to pull the two elastic arms outwards, so that the card head can be separated from the upper surface of the convex block, and then the mesh cover can be quickly pulled downwards; finally, the convenient disassembly and assembly of the mesh cover at the lower end of the suction pipe can be realized;

[0019] 5. By using the guiding inclined plane opened on the inner wall of the lower side of the card hole, the guiding inclined plane can be used for the inclined plane of the card head to abut against, so as to play a guiding role for the card head to be embedded in the card hole, which is conducive to the card head smoothly embedding in the card hole and then being clamped on the upper surface of the convex block;

[0020] 6. By using the embedding end provided at the upper end of the mesh cover, the embedding end can be embedded in the lower end of the suction pipe, which is conducive to the stable connection between the mesh cover and the suction pipe. BRIEF DESCRIPTION OF THE DRAWINGS
