Abstract
The utility model relates to a novel top cover and a seat ring sealing structure, comprising a seat ring, a top cover, a press plate and a bolt, wherein a matching surface of the top cover and the seat ring is provided with a groove, a sealing ring is arranged in the groove and comprises an upper part V-shaped seal ring and a dumbbell-shaped seal ring at the lower part of a V-shaped seal ring, and the press plate is pressed under the lower part of the dumbbell-shaped seal ring. Through utilizing the novel top cover and seat ring sealing structure disclosed by the utility model, multiple units are overhauled after running for a certain term, and the top cover does not leak water so that the multiple units are effectively ensured to safely and stably run.
Description
Technical field
The utility model relates to a kind of novel top cover and seat ring sealing configuration.
Background technique
The mixed-flow wheel unit is designed with sealing at top cover and stops the water in the spiral case to flow in the water wheel chamber top cover between seat ring.At present, the rubber seal of " o " type is adopted in the sealing of certain mixed-flow wheel machine cap and seat ring, and top cover and seat ring sealing configuration are as shown in Figure 1, and it comprises 1, seat ring; 2, top cover; 3, pressing plate; 4, bolt; 5, backing plate; 6, " o " type rubber seal.Because the sealing groove width that seat ring and top cover form is uneven, cause " o " type seal compression uneven, the preceding variation in water pressure of movable guide vane is bigger when again unit operation being arranged; The vibration of unit causes the rubber seal of " o " type between top cover and seat ring, to rub, and grows with time factors such as seal aging; Water leakage phenomenon takes place between top cover and the sealing easily; When water leakage surpasses head cover drainage facility maximum displacement, will cause that the top cover water level goes up, and causes the water logging top cover when serious.
The model utility content
The technical problem that the utility model will solve is for a kind of novel top cover and seat ring sealing configuration are provided, and it is simple in structure, good sealing effect, long service life.
The purpose of the utility model is achieved in that
A kind of novel top cover and seat ring sealing configuration; It comprises seat ring, top cover, pressing plate and bolt; Top cover and seat ring fitting surface are provided with groove; Be provided with seal ring in the groove, described seal ring comprises the V-shaped seal ring on top and the dumbbell shape seal ring of V-shaped seal ring bottom, and pressing plate is pressed in dumbbell seal ring bottom.
Be provided with sealer between above-mentioned dumbbell seal ring and the pressing plate.
Technique effect below the utility model has been obtained:
1. utilize the utility model through too much checking that top cover does not have water leakage phenomenon after platform unit operation a period of time, effectively guaranteed unit safety stable operation.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the prior art constructions schematic representation;
Fig. 2 does not install preceding structural representation for seal ring in the utility model;
Fig. 3 is the structural representation of the utility model.
Embodiment
Shown in Fig. 2-3; A kind of novel top cover and seat ring sealing configuration; It comprises seat ring 1, top cover 2, pressing plate 3 and bolt, and top cover and seat ring fitting surface are provided with groove, are provided with seal ring in the groove; Described seal ring comprises the V-shaped seal ring 7 on top and the dumbbell shape seal ring 8 of V-shaped seal ring bottom, and pressing plate is pressed in dumbbell seal ring bottom.Be provided with sealer between described dumbbell seal ring and the pressing plate.
The installation process of the utility model:
1, cleans out seal groove; Towards the seal groove bottom, segmentation is pressed in the groove with the v shaped ring root, lets v shaped ring heel and seal groove bottom be adjacent to and (v shaped ring opening position is installed earlier; Jointing is in place earlier, again v shaped ring segmentation along the circumferential direction is pressed into seal groove).Can be in seal groove in the installation process apply grease, reduce the friction resistance;
2, the dumbbell-like shape circle is installed.Dumbbell-like shape circle interface position is installed earlier; Make the interface position of dumbbell-like shape circle get in the seal groove fully; Keep good binding, and fit with the V-type circle (note dumbbell-like shape circle interface and v shaped ring interface stagger at least 90 spend), along the circumferential direction the segmentation of dumbbell-like shape circle is pressed in the seal groove;
3, inspection whole erection, whether dumbbell-like shape circle and v shaped ring are in place fully, and the place that bloats or arch upward must not appear in jointing particularly, dumbbell-like shape circle;
4, after the dumbbell-like shape circle is in place,, squeeze into 598 sealers along medial and lateral, dumbbell-like shape circle bottom;
5, pressing plate 3 and bolt (not shown among Fig. 3, concrete installation can the Fig. 1 referring to existing technology in) be installed.
Claims (2)
1. novel top cover and seat ring sealing configuration; It comprises seat ring (1), top cover (2), pressing plate (3) and bolt; Top cover and seat ring fitting surface are provided with groove; Be provided with seal ring in the groove, it is characterized in that: described seal ring comprises the V-shaped seal ring (7) on top and the dumbbell shape seal ring (8) of V-shaped seal ring bottom, and pressing plate is pressed in dumbbell seal ring bottom.
2. novel top cover according to claim 1 and seat ring sealing configuration is characterized in that: be provided with sealer between described dumbbell seal ring and the pressing plate.
