Abstract
The utility model relates to a sealing device for valves, in particular to a valve packing ring, and belongs to the technical field of valve sealing. The valve packing ring of the utility model is connected into a ring through two ends of a packing strip, the adhesion parts of two ends of the packing trip are manufactured into oblique surfaces which mutually correspond, and the oblique surfaces form inclined angles with the end surface of the packing ring. The valve packing ring has the beneficial effects of simple structure and convenient manufacture, saves steps of manufacturing dies, saves cost, and improves the efficiency simultaneously.
Description
Technical field
The utility model relates to a kind of valve seal arrangement, and especially a kind of valve sealing ring belongs to the valve seal technical field.
Background technique
In China, the reduction valve seal ring that uses in the extraordinary gas-tight door of nuclear power station all is from external import.Because seal ring is various in style, and needs to have increased production cost virtually according to each kind, each size custom mold on making, in the cycle of the buying that extended, efficient can't improve.
The model utility content
The purpose of this utility model is the shortcoming that exists at prior art, proposes a kind of valve sealing ring, can make flexibly at different specification requirements.
The purpose of this utility model is realized by following technological scheme: a kind of valve sealing ring, two ends by Stamping Steel Ribbon connect into ring, its improvements are: the inclined-plane of mutual correspondence is made in the abutting edge, two ends of described Stamping Steel Ribbon, and the end face of described inclined-plane and seal ring forms the oblique angle
What the utility model was further perfect is: the oblique angle of described Stamping Steel Ribbon one end is the forward elevation angle, and the oblique angle of the other end is the reverse angle of depression.
What the utility model was further perfect is: described oblique angle is 30 ° ± 5 °.
The beneficial effects of the utility model are simple in structure, and are easy to make, only need calculate the length of Stamping Steel Ribbon as requested, are connected to form seal ring after its two ends being made 30 ° oblique angle.During use, the interface of seal ring is in by the pressure form, does not influence sealing effect.Save the step of manufacturing mould, improved efficient when saving cost.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model embodiment when not bonding.
Fig. 2 is the bonding elevation as a result of the utility model embodiment Fig. 1.
Fig. 3 is the utility model embodiment's a bonding floor map as a result.
Fig. 4 is the stereogram of the utility model embodiment Fig. 3.
Embodiment
Embodiment
The structure of present embodiment as shown in Figures 1 to 4, a kind of valve sealing ring, connecting into ring by the two ends of Stamping Steel Ribbon 1 constitutes, the inclined-plane of mutual correspondence is made in the joint, two ends of Stamping Steel Ribbon 1, the end face of inclined-plane and seal ring forms the oblique angle, the oblique angle of Stamping Steel Ribbon one end is the forward elevation angle 2, and the oblique angle of the other end is that 3, two jiaos at the reverse angle of depression is 30 °.
During making, calculate the length of Stamping Steel Ribbon as requested, the Stamping Steel Ribbon two ends are made 30 ° the forward elevation angle 2 and the reverse angle of depression 3, and bonding, suppress seal ring then, as shown in Figure 4.During use, the interface of seal ring is in by the pressure form, does not influence sealing effect.Save the step of making mould, improved efficient when saving cost.
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
Claims (3)
1. a valve sealing ring is made of the bonding one-tenth ring in Stamping Steel Ribbon two ends, and it is characterized in that: the inclined-plane of mutual correspondence is made in the abutting edge, two ends of described Stamping Steel Ribbon, and the end face of described inclined-plane and seal ring forms the oblique angle.
2. valve sealing ring according to claim 1 is characterized in that: the oblique angle of described Stamping Steel Ribbon one end is the forward elevation angle, and the oblique angle of the other end is the reverse angle of depression.
