A sealing ring is matched between the flange and the sealing cover.

The top surface of the ring body of the sealing ring is wide and the bottom surface is narrow, so that the outer surface of the ring body is a wedge-shaped surface; a compression ring with a thickness smaller than that of the sealing ring is arranged between the flange and the sealing cover, and the compression ring is arranged between the flange and the sealing cover. A wedge-shaped surface matching with the wedge-shaped surface of the sealing ring is provided on the tightening ring; a screw that penetrates the flange and presses against the compression ring is arranged on the bottom surface of the flange.

The upper surface of the sealing cover is provided with a card slot, and the upper end of the C-shaped buckle fits in the card slot.

The pipe sleeve is made of copper material.

Compared with the prior art, the utility model has the following advantages and beneficial effects:

(1) The pipe end sealing structure of the utility model enhances the sealing performance of the pipe end through the cooperation of C-shaped buckles, pipe sleeves, sealing covers, rubber sealing rings, and gaskets.

(2) The set sealing ring further enhances the sealing performance. The compression ring cooperates with the sealing ring to further enhance the sealing performance.

(3) The upper end of the C-shaped buckle fits in the slot, which can prevent the C-shaped buckle from slipping and improve the stability.

detailed description

The utility model will be further described in detail below in conjunction with the examples, but the implementation of the utility model is not limited thereto.

Example 1:

As shown in Figure 1, the pipe end sealing structure of the present invention includes a sealing cover 3, a pipe body 1, a flange 6 and an elastic C-shaped buckle 11. The pipe body 1 is covered with a pipe sleeve 2, The sealing cover 3 covers the end of the pipe body 1; a rubber sealing ring 4 is provided at the joint of the pipe sleeve 2, the pipe body 1 and the sealing cover 3 and a corresponding sealing gasket 5 is provided; The flange 6 is sleeved with a part close to the sealing cover 3 on the pipe sleeve 2, and the upper end and the lower end of the C-shaped buckle 11 are fitted on the upper surface of the sealing cover 3 and the lower surface of the flange 6 respectively. The pipe end sealing structure of the utility model enhances the sealing performance of the pipe end through the cooperation of the C-shaped buckle 11, the pipe sleeve 2, the sealing cover 3, the rubber sealing ring 4, and the sealing gasket 5. When in use, first install the pipe body 1 and the pipe sleeve 2, then put the sealing gasket 5 and the rubber sealing ring 4 into it, then cover the sealing cover 3, and finally install the C-shaped buckle 11 to press the sealing cover 3, compared with In terms of thread structure sealing, the sealing performance is improved, and no rust will cause difficulty in opening the sealing cover.

Example 2:

Preferably, a sealing ring 7 is fitted between the flange 6 and the sealing cover 3 to further improve the sealing performance. The setting of the rubber sealing ring 4 and the sealing ring 7 one inside and one outside improves the sealing performance as a whole.

Example 3:

As preferably, the top surface of the ring body of the sealing ring 7 is wide and the bottom surface is narrow, so that the outer surface of the ring body is a wedge-shaped surface; Thickness of the compression ring 8, the compression ring 8 is provided with a wedge-shaped surface that matches the wedge-shaped surface of the sealing ring 7; the bottom surface of the flange 6 is provided with a screw 9 that penetrates the flange 6 and presses the compression ring 8 . During use, the compression ring 8 is moved upward by turning the screw 9, and the wedge-shaped surface of the compression ring 8 exerts a force on the wedge-shaped surface of the sealing ring 7, so that the sealing ring 7 is more tightly attached to the sealing cover 3 and the pipe sleeve 2, thereby Improved sealing performance.
