This structure has poor sealing performance, low bearing pressure and short service life.

SUMMARY OF THE INVENTION

The technical problem solved by the present utility model is to provide an annular nozzle:

The purpose of the present utility model can be achieved through the following technical solutions:

An annular spray head, including an inner ring 9, a pressure-bearing ring 8, the pressure-bearing ring 8 is ring-connected outside the inner ring 9 to form a tight annular body, and a ring is provided at the contact of the pressure-bearing ring 8 and the inner ring 9 in the annular body. A hollow ring, a plurality of hollow structures are arranged in the annular body toward the center of the circle, a nozzle 2 is arranged in the hollow structure, the nozzle of the nozzle 2 is arranged at the inner wall of the annular body, the nozzle 2 is connected with the hollow ring, and the annular The body is provided with a liquid inlet joint 5, and the liquid inlet joint 5 is arranged coplanar with the annular body. The inflow passes through the hollow ring into the nozzle and exits.

Preferably, the nozzle 2 is fixed in the pressure-bearing ring 8 through a screw plug, a sealing washer 4 is provided at the nozzle of the nozzle 2 to connect with the inner ring 9 , and a through hole for supplying water is provided in the middle of the sealing washer 4 .

Preferably, a first sealing ring 7 is provided at the connection between the sealing gasket 4 and the inner ring 9 .

Preferably, six hollow structures are provided, and the six hollow structures are sequentially distributed in the annular body at equal angular intervals.

Preferably, the nozzle 2 is provided with a second sealing ring 3 at the edge of the pressure-bearing ring 8.

Preferably, two sealing rings are provided at the connecting surfaces of the pressure bearing ring 8 and the inner ring 9 .

Preferably, two third sealing rings 6 are provided at the connection between the liquid inlet joint 5 and the pressure bearing ring 8.

The beneficial effects of the present utility model:

This ring-shaped sprinkler has high sealing performance, strong bearing pressure, convenient use and long service life.

Detailed ways

As shown in the accompanying drawings, the technical scheme of the present utility model is further described:

An annular spray head, including an inner ring 9, a pressure-bearing ring 8, the pressure-bearing ring 8 is ring-connected outside the inner ring 9 to form a tight annular body, and a ring is provided at the contact of the pressure-bearing ring 8 and the inner ring 9 in the annular body. A hollow ring, a plurality of hollow structures are arranged in the annular body toward the center of the circle, a nozzle 2 is arranged in the hollow structure, the nozzle of the nozzle 2 is arranged at the inner wall of the annular body, the nozzle 2 is connected with the hollow ring, and the annular The body is provided with a liquid inlet joint 5, and the liquid inlet joint 5 is arranged coplanar with the annular body. The inflow passes through the hollow ring into the nozzle and exits.

In this embodiment, preferably, the nozzle 2 is fixed in the pressure-bearing ring 8 through a screw plug, a sealing washer 4 is provided at the nozzle of the nozzle 2 to connect with the inner ring 9, and a water supplying water supply is arranged in the middle of the sealing washer 4. through hole.

In this embodiment, preferably, a first sealing ring 7 is provided at the connection between the sealing gasket 4 and the inner ring 9 .

In this embodiment, preferably, six hollow structures are provided, and the six hollow structures are sequentially distributed in the annular body at equal angular intervals.

In this embodiment, preferably, the nozzle 2 is provided with a second sealing ring 3 at the edge of the pressure bearing ring 8 .

In this embodiment, preferably, two sealing rings are provided at the connecting surfaces of the pressure bearing ring 8 and the inner ring 9 .
