Abstract
The utility model provides a seal ring dedicated for a multi-point double-lip PE double-wall corrugated pipe. A first lip and a second lip are arranged at the outer ring of the seal ring, so that thecross section of the seal ring is Y-shaped, and the two lips are in interference fit with the socket of the double-wall corrugated pipe with an interference amount ranging from 5 mm to 10 mm. In the structure and design perspectives, the seal ring fits well with the wave shape of the corrugated pipe. The seal ring is designed with the double seal lips, therefore the rubber gasket double lips are in contact with the inner wall of the pipe socket to generate the interference compression deformation, and simultaneously the gap between the two lips forms a mechanical water seal trough. Instead ofthe design of the rubber gasket inner ring in contact with the wave trough in the prior art, the seal ring adopts the design that the enough space is reserved between the rubber gasket inner ring andthe wave trough, and the interference amount between the section of the seal ring and the wave-shaped section of the double-wall corrugated pipe is controlled within the range from 5% to 15%; and therubber gasket slides downwards under the compression of the pipe socket, so that the side surface of the rubber gasket and the wave-shaped side surface of the pipe form the multi-point compression interference fit to seal. The seal ring thoroughly solves the sealing problem of the pipe connection, and achieves the reliable seal of one rubber gasket.
Description
[technical field]:
The utility model belongs to the water and wastewater piping engineering technical field, relates to a kind of being applicable to and buries the sealing of ground draining with PE double-wall corrugated pipe connection mouth, belongs to the rubber elasticity Sealing.
[background technique]:
Burying ground draining plastic pipe industry, great majority rubber seal sealed interface mode, majority is two dot encapsulations, it is the lip top contact tubing bellmouth inwall of cushion rubber, cushion rubber inner ring bottom contact tubing trough forms two dot encapsulations, and majority is single lip structure, and sealing effect is relatively poor.In order to improve two O-ring seals of the most employings of sealing, both increased the pipeline link cost, waste time and energy again.
[model utility content]:
The utility model purpose is to overcome above shortcomings in the prior art, and a kind of multiple spot lips PE double-wall corrugated pipe special sealing ring is provided.
The multiple spot lips PE double-wall corrugated pipe special sealing ring that the utility model provides, be that the first and second two lips are arranged in the outer ring of seal ring, making the cross section of seal ring Y-shaped, is interference fit between two lips and the double-wall corrugated tube faucet, and the interference decrement is 5-10mm.
The inner ring of seal ring and the waveform of double-wall corrugated pipe matches and for interference fit, the internal diameter of seal ring inner ring bottom is greater than the external diameter of double-wall corrugated pipe trough bottom, make between the bottom of the inner ring bottom of seal ring and double-wall corrugated pipe trough and leave the gap, the magnitude of interference between seal ring section and double-wall corrugated pipe waveform section is controlled at 5-15%.
Advantage of the present utility model and good effect:
The multiple spot lips sealing structure cushion rubber of the utility model design, on structure, match with the tubing waveform in the design, and be designed to the double-sealing lip, make cushion rubber lips mouth contact and form the interference compress variation with tubing bellmouth inwall, groove between two lips forms mechanical seal tank simultaneously, and the design changes the design philosophy that the cushion rubber inner ring contacts with trough in the prior art, make and stay enough spaces between cushion rubber inner ring and the trough, for cushion rubber downward slippage when the bellmouth compression force, and then form and to make cushion rubber texture edge and tubing waveform side form multiple spot to compress and seal, thoroughly solve the sealing problem that tubing connects, and realized the reliable sealing of a cushion rubber.
[description of drawings]:
Fig. 1 is a cross section of the present utility model sectional structure schematic representation.
Fig. 2 is that the utility model is at the partial structurtes schematic representation that connects in using.
Among the figure, 1 multiple spot lips PE double-wall corrugated pipe seal ring, 2 first lips, 3 second lips, 4 double-wall corrugated pipes, 5 double-wall corrugated tube faucets, groove between the 6 lips mouths, L1, L2, L3, L4 are the corresponding site width, R1, R2 are the corresponding site chamfer radius,
[embodiment]:
Embodiment 1:
As shown in Figure 1, the multiple spot lips PE double-wall corrugated pipe special sealing ring 1 that the utility model provides, be the design of double-sealing lip, the outer ring that is seal ring is provided with first lip 2 and second lip 3, make the cross section of seal ring Y-shaped, be interference fit between two lips and the double-wall corrugated tube faucet, the interference decrement is 5-10mm.
Simultaneously, the inner ring of seal ring on structure, in the design with the tubing waveform and size matches and be interference fit, and the internal diameter of seal ring inner ring bottom is greater than the external diameter of double-wall corrugated pipe trough bottom, makes between the bottom of the inner ring bottom of seal ring and double-wall corrugated pipe trough and leaves the gap.
The utility model is at the partial structurtes schematic representation that connects in using as shown in Figure 2, the lips mouth 2 of multiple spot lips PE double-wall corrugated pipe special sealing ring 1 contacts with double-wall corrugated tube faucet 5 inwalls with 3, and formation interference compress variation, groove between first lip 2 and second lip 36 forms mechanical seal tank simultaneously, and the design philosophy that the cushion rubber inner ring contacts with trough is changed in design, make between multiple spot lips PE double-wall corrugated pipe seal ring 1 inner ring bottom and the double-wall corrugated pipe 4 troughs bottom and stay enough spaces, for seal ring 1 downward slippage when bellmouth 5 compression force, and then make seal ring 1 texture edge and tubing 4 waveform sides form multiple spot compression interference fit and seal, the magnitude of interference between seal ring 1 section and double-wall corrugated pipe 4 waveform sections is controlled at 5-15%.
Claims (3)
