As a preferred technical scheme: the upper end and the lower end of the annular edge of the throttling ring and the water seal ring are higher than the ring body.

As a preferred technical scheme: and labyrinth seals are arranged between the throttling ring and the ring body on the left side of the water seal ring.

As a preferred technical scheme: the split type throttling ring and the water seal ring are fixedly assembled through a bayonet structure, and the bayonet structure is fixed on the ring edge on the right side through a connecting bolt.

The utility model has special structure, introduced pressure relief principle and throttle idea; the external washing water is drained into the equipment, the pressure of external filler is reduced, and the medium in the equipment is isolated, so that the filler is fully cooled, and the service life of the filler is prolonged; the water pressure at the sealing position of the filler is reduced, and simultaneously, solid particles in the equipment are isolated, so that the filler is protected; the mounted stuffing box can be pulled out through threads; the split type throttling ring and the water seal ring are more convenient to assemble, disassemble and replace.

Detailed Description

The present invention will be further described with reference to the accompanying drawings, which are not intended as limitations of the present invention: the utility model provides a multi-functional throttle ring and water seal ring which characterized in that: the water seal ring comprises a throttle ring 1 and a water seal ring 2, wherein the throttle ring 1 is arranged in front of the water seal ring 2, and the throttle ring 1 is matched with the water seal ring 2 for use; the throttling ring 1 and the water seal ring 2 are both of split structures, the throttling ring 1 and the water seal ring 2 both comprise an annular edge 3 and an annular body 4, a plurality of pressure relief drainage slotted openings 5 are uniformly arranged on the annular edge 3 on the left side of the throttling ring 1 and the water seal ring 2, and a plurality of thread taking holes 6 are uniformly arranged on the annular edge 3 on the right side; the ring body 4 is provided with a washing water inlet area 7, a washing water inlet hole 8 and a washing water outlet area 9, the washing water inlet area 7 is communicated with the washing water outlet area 9 through the washing water inlet hole 8, and the washing water inlet holes 8 are uniformly arranged on the ring body 4.

The upper end and the lower end of the annular edge 3 of the throttling ring 1 and the water seal ring 2 are higher than the ring body 4. And labyrinth seals 10 are arranged on ring bodies on the left sides of the throttling ring 1 and the water seal ring 2. The split type throttling ring 1 and the water seal ring 2 are fixedly assembled through a bayonet structure 11, and the bayonet structure 11 is fixed on the ring edge 4 on the right side through a connecting bolt 12.

In the specific implementation: dividing the ring into two parts by a ring body dividing line to form a split structure; when the single ring is installed, the labyrinth seal is placed in the equipment to prevent solid particles in the equipment from entering the shaft seal; protecting the filler behind; external washing water enters the area along the washing water, enters the washing water and enters the annular hole, and water flows normally to the two sides of the annular body through the washing water outlet area and flows out. The water flow can be led out to the inside of the equipment in advance through the pressure relief drainage slotted opening, and a pressure relief channel is formed at the moment to guide external flushing water to flow to the inside of the equipment; the split connecting bolts can ensure that the ring body can synchronously move inwards when the packing gland compresses the packing, so that the dislocation of the ring body is prevented, the sealing effect is reduced, and the disassembly is difficult; the threaded removal hole ensures that the ring body can be removed by threading.
