Abstract
The utility model discloses an inlet check valve sealing device for a high-temperature high-pressure set. The inlet check valve sealing device comprises a sealing body cooperating with a valve body and a sealing ring arranged between the sealing body and the valve body. The upper surface and the lower surface of the sealing ring are each provided with a grading ring, and the cross section of the sealing ring is rectangular. The internal diameter of the sealing ring is 234mm, the external diameter of the sealing ring is 254mm, and the height of the sealing ring is 30mm or 25mm. The sealing ring employs high-pressure moulded graphite filling material. The inlet check valve sealing device, when employing high-pressure moulded graphite filling material, completely prevents leakage.
Description
Technical field
The utility model specifically discloses a kind of High Temperature High Pressure unit import non-return flap seal arrangement.
Background technique
Large scale industry unit adopts high temperature, high pressure design, steam-water pipe is generally designed to import gate valve, non-return flap, its seal ring is soft metal selfsealings circles, in normal operation because frequent starting causes face leakage, even if also occur leaking after more renewing flexible metal sealing washer, unit operation caused to very large threat.
Model utility content
The shortcoming existing in order to solve prior art, the utility model specifically discloses a kind of High Temperature High Pressure unit import non-return flap seal arrangement.
The technical solution adopted in the utility model is as follows:
High Temperature High Pressure unit import non-return flap seal arrangement, comprise seal and seal ring, described seal coordinates with valve body, and is provided with seal ring between seal and valve body, upper surface and the lower surface of described seal ring are equipped with piezometer ring, and the cross section of seal ring is rectangle.
The internal diameter of described seal ring is 234mm, and external diameter is 254mm.
The height of described seal ring is 30mm or 25mm.
What described seal ring adopted is high-pressure molding graphite packing.
The beneficial effects of the utility model are:
After transforming high-pressure molding graphite flexible filler as, can thoroughly stop a leak.
Accompanying drawing explanation
Schematic diagram before the transformation of Fig. 1 non-return flap seal ring;
Schematic diagram after the transformation of Fig. 2 non-return flap seal ring;
Schematic diagram after the transformation of Fig. 3 seal ring;
Schematic diagram before the transformation of Fig. 4 seal ring;
1 valve body in figure, 2 seals, 3 piezometer rings, 4 former seal rings, 5 improved seal rings.
Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated:
As Figure 1-4, High Temperature High Pressure unit import non-return flap seal arrangement, comprise seal 2 and seal ring, described seal 2 coordinates with valve body 1, and between seal 2 and valve body 1, be provided with seal ring, as shown in Figure 3, improved seal ring 5 as shown in Figure 4 for former seal ring 4, the upper surface of improved seal ring 5 and lower surface are equipped with piezometer ring 3, and the cross section of improved seal ring 5 is rectangle.
The internal diameter of improved seal ring 5 is 234mm, and external diameter is 254mm.
The height of improved seal ring 5 is 30mm or 25mm.
What improved seal ring 5 adopted is high-pressure molding graphite packing.
