Abstract
The invention relates to a seal mechanism located between a flue valve and a cooling water pipe. The seal mechanism comprises a valve cover and the cooling water pipe. A first through hole is formed in the bottom of the valve cover, and a stuffing box is arranged in the valve cover. A second through hole is formed in the bottom of the stuffing box, and the central line of the second through hole coincides with the central line of the first through hole. One end of the cooling water pipe sequentially penetrates through the first through hole and the second through hole to extend into the stuffing box. A seal ring is arranged between the outer wall of the bottom of the stuffing box and the inner wall of the bottom of the valve cover. The seal mechanism located between the flue valve and the cooling water pipe is characterized in that a groove is machined in the outer wall of the bottom of the stuffing box, the cross section of the seal ring is circular, the top of the seal ring is tightly connected with the bottom of the groove of the stuffing box, and the bottom of the seal ring is tightly connected with the inner wall of the bottom of the valve cover. The intensity of pressure borne by the seal ring in the seal mechanism is large, so that seal performance is good.
Description
Technical field
The present invention relates to a kind of sealing mechanism, is the sealing mechanism being positioned between chimney valve and water-cooling tube specifically.
Background technique
In the valve field of manufacturing, all know, in order to prevent the joint leakage cigarette of chimney valve and water-cooling tube, between chimney valve and water-cooling tube, conventionally all sealing mechanism can be installed.
At present, traditional sealing mechanism being positioned between chimney valve and water-cooling tube comprises valve gap and water-cooling tube.The first through hole is arranged at the bottom of described valve gap, and there is Stuffing box its inside.The second through hole is arranged at the bottom of described Stuffing box, and the center line of the second through hole overlaps with the center line of the first through hole; One end of described water-cooling tube is passed the first through hole, the second through hole successively, and reaches in Stuffing box.Between the inwall of the bottom outer wall of Stuffing box and valve gap bottom, there is seal ring.The section of described seal ring is rectangular.Because the section of the seal ring between the inwall of the bottom outer wall of Stuffing box in sealing mechanism and valve gap bottom is rectangular, so the area of contact of seal ring and Stuffing box and valve gap bottom is just larger, the pressure that seal ring is subject to is less, and sealability is poor.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of sealing mechanism being positioned between chimney valve and water-cooling tube, and the pressure that the seal ring in sealing mechanism is subject to is large, sealability is better.
For addressing the above problem, provide following technological scheme:
The sealing mechanism being positioned between chimney valve and water-cooling tube of the present invention comprises valve gap and water-cooling tube.The first through hole is arranged at the bottom of described valve gap, and there is Stuffing box its inside.The second through hole is arranged at the bottom of described Stuffing box, and the center line of the second through hole overlaps with the center line of the first through hole.One end of described water-cooling tube is passed the first through hole, the second through hole successively, and reaches in Stuffing box.Between the inwall of the bottom outer wall of described Stuffing box and valve gap bottom, there is seal ring.Be characterized in being processed with groove in the bottom outer wall of described Stuffing box, the section of described seal ring is circular, and the top of seal ring is closely connected between being with the bottom land of Stuffing box groove, is tight and is connected between the inwall bottom the bottom of seal ring and described valve gap.
Wherein, described seal ring is made by rubber.
Take above scheme, have the following advantages:
In bottom outer wall due to the Stuffing box that is positioned at the sealing mechanism between chimney valve and water-cooling tube of the present invention, be processed with groove, the section of described seal ring is circular, the top of seal ring is closely connected between being with the bottom land of Stuffing box groove, is tight and is connected between the inwall of the bottom of seal ring and described valve gap bottom.So the area of contact of seal ring and Stuffing box and valve gap is less, the pressure that seal ring bears is just larger, thereby has improved sealability.
Accompanying drawing explanation
Fig. 1 is the structural representation that is positioned at the sealing mechanism between chimney valve and water-cooling tube of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the sealing mechanism being positioned between chimney valve and water-cooling tube of the present invention is described in further detail.
As shown in Figure 1, the sealing mechanism being positioned between chimney valve and water-cooling tube of the present invention comprises valve gap 2 and water-cooling tube 4.The first through hole is arranged at the bottom of described valve gap 2, and there is Stuffing box 1 its inside.The second through hole is arranged at the bottom of described Stuffing box 1, and the center line of the second through hole overlaps with the center line of the first through hole.One end of described water-cooling tube 4 is passed the first through hole, the second through hole successively, and reaches in Stuffing box 1.Between the inwall of the bottom outer wall of described Stuffing box 1 and valve gap 2 bottoms, there is seal ring 3.In the bottom outer wall of described Stuffing box 1, be processed with groove 5, the section of described seal ring 3 is circular, and the top of seal ring 3 is closely connected between being with the bottom land of Stuffing box 1 groove 5, is tight and is connected between the inwall of the bottom of seal ring 3 and described valve gap 2 bottoms.Seal ring described in the present embodiment 3 has rubber to make.
During use, thereby utilize the sealing that has completed valve gap 2 and coordinating of Stuffing box 14 of chimney valve and water-cooling tubes.
