Abstract
The utility model belongs to a sealing element for a pipeline valve, which is composed of a press cover and a sealing ring arranged on a valve rod. The utility model is characterized in that the sealing ring is composed of a supporting loop, a sealing loop and a pressure loop; the sealing ring forms a V shape, and forms an angle of 90 DEG plus and minus 2 DEG; the angles of the supporting loop and the pressure loop are respectively larger than the angle of the V-shaped sealing loop; an inner angle of the V-shaped sealing ring is provided with a small groove. The utility model has the advantages of simple structure, reliable sealing performance, strong sealing element wear resistant property, good corrosion resistant property and long service life.
Description
The utility model belongs to the pipe valve seal element.
As everyone knows, the sealing kind of existing valve is a lot, most graphite asbestos packing or gum circles of adopting, sealing effect is undesirable, the dielectric leakage phenomenon often occurs, and water resources is caused waste, especially winter, it was cold, and the water that spills easily freezes, and causes very big difficulty to maintenance.This in addition packing seal also exists following shortcoming: friction ractor is big, needs bigger screwing force, otherwise leaks.And working life is short.
The purpose of this utility model provides a kind of simple in structure, and sealability is reliable, a kind of valve novel seal element of long service life.
Another purpose of the present utility model provides and a kind ofly improves that seal element is wear-resisting, a kind of valve novel seal element of corrosion resisting property.
The utility model is to realize like this, it is made up of gland nut, the seal ring that is arranged on the valve rod, it is characterized in that seal ring is made up of supporting ring, seal ring, pressure ring, its seal ring is " V " shape, be 90 ° ± 2 ° angles, the angle of supporting ring and pressure ring is slightly larger than the angle of " V " V-shaped ring, has a little groove at the interior angle place of " V " shape seal ring.
Another main points of the present utility model are that seal ring is made by teflon.
The utility model has the advantages that:
1, sealing is more reliable.Owing to adopted said structure and material; Prevent the leakage at stuffing box place.
2, simple and reasonable.Because this novel seal ring angle is rationally made with the employing teflon, its friction ractor is little, and is laborsaving, energy-conservation, and wear resistance is good, long service life.
3, extensive applicability.Because it is strong to the utlity model has good sealing property, corrosion resistance, weathering resistance, has self lubricity, therefore, can be widely used in conveying gas, various liquid, comprise the valve seal in the pipeline of strong acid, highly basic liquid and various oil, Korrosionsmedium.
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing 1 is that the utility model packing seal element is contained in the structural representation sectional drawing on the valve.
Accompanying drawing 3 is the utility model seal element assembling free state figure.
Accompanying drawing 4 is the utility model pressurization back packing seal element stress deformation figure.
Referring to accompanying drawing 1,2,3, the utility model is made up of gland 2, the seal ring that is arranged on the valve rod 1, it is characterized in that seal ring is made up of supporting ring 3, seal ring 4, pressure ring 5, its seal ring is " V " shape, be 90 ° ± 2 ° angles, the angle of supporting ring 3 and pressure ring 5 is slightly larger than the angle of " V " V-shaped ring 4, has a little groove at the interior angle place of " V " shape seal ring.For increasing the wear resistance of Sealing, seal ring of the present utility model adopts teflon to make.
After this packing seal element is packed the valve packing letter into, by 2 pairs of Sealings of gland P that exerts pressure,, Sealing produces distortion under the effect of P power, and makes between itself and valve rod 1, valve body 2 fitting surfaces and produce pressure, sees Fig. 4.This pressure is far longer than the directed force F of the interior liquid of valve to valve body, valve lever clearance, produces good sealing effect.Therefore use the utility model under high pressure, also can not leak, and seal ring is quick detachable, easily changes, be fit to use with the occasion of seal request strictness.
Claims (2)
1, a kind of valve new packing seal element, it is made up of gland (2), the seal ring that is arranged on the valve rod (1), it is characterized in that seal element is made up of supporting ring (3), seal ring (4), pressure ring (5), its seal ring is " V " shape, be 90 ° ± 2 ° angles, the angle of supporting ring (3) and pressure ring (5) is slightly larger than the angle of " V " V-shaped ring (4), has a little groove at the interior angle place of " V " type seal ring (4).
2, valve according to claim 1 new packing seal element is characterized in that seal ring made by teflon.
