As shown in fig. 1, one embodiment of a slotted header is provided.

Specifically, the cover body 10 is provided, and the cover body 10 is disc-shaped, so that the manufacture and the arrangement are convenient.

One side of the cover body 10 is provided with a sealing ring 20, the sealing ring 20 is used for being matched and sealed with the sealing gasket and the valve plate, and the outer side and the inner side of the sealing ring 20 are respectively used for forming a water inlet channel 80 and a water outlet channel 90.

Correspondingly, a water inlet joint 70 and a water outlet joint 60 are arranged on the other side of the cover body 10, and the axis of the water inlet joint 70 and the axis of the water outlet joint 60 are arranged in parallel with the axis of the cover body 10, so that the manufacturing is convenient.

The inside of sealing ring 20 is provided with annular muscle 30, and annular muscle 30 is used for the spacing leak protection pad of butt, and the inboard holding water of annular muscle 30 flows out, and specific theory of operation can refer to a long-life water pump, patent document 201720768258.5 for a patent.

Because the sealing rib and the annular rib 30 are both connected with the cover body 10, a semi-closed space is formed between the inner side of the sealing rib and the outer side of the annular rib 30, when water enters the water outlet channel 90 through the anti-leakage pad, the water flows out after filling the semi-closed space, but when the water pump stops working, the water in the semi-closed space is difficult to flow out, and the water is accumulated.

To solve this problem, the present embodiment is characterized in that a notch is provided at the end of the annular rib 30, and the notch communicates the inside and the outside of the annular rib 30.

Because the gap communicates the semi-enclosed space with the water outlet channel 90, water can flow from the gap to the water outlet channel 90 to drain the water, thereby avoiding the accumulation of water.

Of course, the number of indentations may be more than one to try to drain the water clean.

As shown in fig. 2, in order to avoid the strength of the annular rib 30 from being reduced after the notch is formed, the inner surface of the seal ring 20 may be provided with a connecting rib 50 connecting the outer surfaces of the annular rib 30.

In some embodiments, the depth of the gap may also be made equal to the height of the annular bead 30, as shown in fig. 2, to increase the drainage capacity of the gap.

In some embodiments, as shown in fig. 3, the notch may be aligned with the tie bar 50, with the notch extending along the top of the tie bar 50.

To avoid serious blockage of the pump due to a gasket failure, the end of the sealing ring 20 may be provided with an opening 22 aligned with the notch, as shown in fig. 3, so that a small amount of water enters and exits through the end face of the sealing ring 20.

As shown in fig. 3, in order to improve the matching ability of the sealing ring 20 and the gasket, and to generate a positioning effect on the gasket while satisfying sealing, a sealing flange 21 may be provided at an end portion of the sealing ring 20, and the sealing flange 21 may extend in a ring shape along a circumferential direction of the sealing ring 20.

As shown in fig. 2, another modification of the water inlet joint 70 is provided, so that the water inlet joint 70 can be arranged along the radial direction of the cover body 10, thereby facilitating the connection of the pipeline.

Of course, the notch is only one type, and may be a communication hole for leaking water, or may be raised as the leakage groove 40.

That is, by providing the leakage groove 40, the semi-closed space between the inner side of the sealing ring 20 and the outer side of the annular rib 30 is communicated with the water outlet channel 90 at the inner side of the annular rib 30, so that water can flow out conveniently; meanwhile, the leakage groove 40 is arranged, so that the sectional area of the water outlet channel is increased, the water outlet resistance is small, the opening obstruction of the leakage-proof pad is small, water can conveniently enter the water outlet channel 90 through the leakage-proof pad, the power consumption of the water pump is reduced, and the water conveying efficiency and capacity of the water pump are improved.

The above embodiments are not limited to the technical solutions of the embodiments themselves, and the embodiments may be combined with each other into a new embodiment.
