Abstract
The utility model discloses a flexible double-lip V-shaped L-shaped seal ring, wherein, the direction close to a circle center of the seal ring is taken as an inward direction, the direction apart from the circle center of the seal ring is taken as an outward direction, and the seal ring comprises an outmost sealing surface and an innermost supporting surface; a ring-shaped groove is formed at the middle part of the sealing surface; the cross section of the ring-shaped groove is V-shaped; both sides of the ring-shaped groove respectively form sealing surfaces, the cross sections of which are in the shape of a single lip; obtuse L-shaped surfaces are formed on the both sides of the sealing surfaces on the outer side of the ring-shaped groove; and the cross section of the supporting surface is a flat-bottomed U-shaped structure with a wide top and a narrow bottom. The flexible double-lip V-shaped L-shaped seal ring is used for mounting an HDPE (high-density polyethylene) double-wall corrugated pipe in a sealing manner, and has the advantages of saving materials, being easy to wriggle, being convenient to install, being not easy to roll and ensuring favorable sealing performance.
Description
Technical field
The utility model relates to a kind of seal ring, relates in particular to a kind of flexible lips VL shape seal ring of sealing installation of the HDPE of being used for double-wall corrugated pipe.
Background technique
Characteristics such as that the HDPE double-wall corrugated pipe has is in light weight, high pressure resistant, good toughness, fast life-span of construction are long.Be widely used in underground ground draining, blow-off line, irrigation and water conservancy irrigation water delivery, water drainage, sewage treatment works, the garbage disposal plant etc. of burying in draining, municipal engineering, residential quarters of building; Long-term water-stop property is the most difficult and most important technical requirements of HDPE double-wall corrugated pipe spigot and socket type interface, and addressing this problem also is one of the most key technology in bellows market.
At present, the seal ring consumption that is used for the HDPE double-wall corrugated pipe on the market is very big, and is also very big to the demand of rubber; The existing seal ring that is used for the HDPE double-wall corrugated pipe; All be solid construction from the sealing surface to the supporting surface, caused the waste of material on the one hand, thicker owing to the center in installation process on the other hand; Constant wriggling is for installation has brought difficulty.
Summary of the invention
The flexible lips VL shape seal ring that the purpose of the utility model is installed with regard to the sealing that is to provide in order to address the above problem a kind of HDPE of being used for double-wall corrugated pipe, this seal ring have to be saved material, be prone to wriggling, be convenient to the advantage installing, be difficult for rolling.
The utility model is realized above-mentioned purpose through following technological scheme:
In the utility model, being inward direction with the direction near the said seal ring center of circle, is outward direction with the direction away from the said seal ring center of circle, and said seal ring comprises the supporting surface of outermost sealing surface and innermost layer; The middle part of said sealing surface is provided with annular groove, and the sectional shape of said annular groove is a V-arrangement, and said annular groove both sides form the sealing surface that the cross section is single lip respectively, and the both sides of the sealing surface in the said annular groove outside form L shaped of obtuse angle; The sectional shape of said supporting surface is a flat U-shaped wide at the top and narrow at the bottom.
In the application process, the sealing surface of the rhombus lips structure of annular groove both sides and the inner face of HDPE double-wall corrugated pipe form sealing, can realize excellent sealing performance.And the design of the lip of sealing surface makes the installation resistance less, and two seal lips can be out of shape with the shape of pipeline when assembling is moved, thus install than be easier to, and utilize its suitable thickness to guarantee excellent sealability; Simultaneously, because the sectional shape of supporting surface is a flat U-shaped wide at the top and narrow at the bottom, thus not only have enough support forces, and be difficult for rolling.
Further, the link position between L shaped of said sealing surface both sides and the said supporting surface forms the acute angle shape face of evagination.Further increased the intensity of support fixation.
As preferably, said seal ring is the rubber seal of hardness between 55～65.
The beneficial effect of the utility model is:
The utility model is used for the sealing of HDPE double-wall corrugated pipe to be installed, and has the material of saving, is prone to wriggling, is convenient to install, is difficult for rolling and can guarantees the advantage of excellent sealing performance, and avoided because of seal ring the problem that upset loses sealing function taking place.
Description of drawings
Fig. 1 is the plan view of the utility model;
Fig. 2 is the A-A amplification view among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As depicted in figs. 1 and 2, be inward direction with direction near the center of circle of seal ring 1, be outward direction with direction away from the center of circle of seal ring 1, seal ring 1 comprises the supporting surface 5 of outermost sealing surface 2 and innermost layer; The middle part of sealing surface 2 is provided with annular groove 4, and the sectional shape of annular groove 4 is a V-arrangement, and annular groove 4 both sides form the sealing surface 2 that the cross section is single lip respectively, and the both sides of the sealing surface 2 in annular groove 4 outsides form L shaped 3 at obtuse angle; The sectional shape of supporting surface 5 is a flat U-shaped wide at the top and narrow at the bottom.Seal ring 1 is the rubber seal of hardness between 55～65.
As shown in Figure 2, the link position between L shaped 3 of sealing surface 2 both sides and the supporting surface 5 forms the acute angle shape face 6 of evagination.Further increased the intensity of support fixation.
As depicted in figs. 1 and 2, in the application process, the sealing surface 2 of the rhombus lips structure of annular groove 4 both sides forms sealing with the inner face of HDPE double-wall corrugated pipe (not shown), can realize excellent sealing performance.And the design of the lip of sealing surface 2 makes the installation resistance less, and two seal lips can be out of shape with the shape of pipeline when assembling is moved, thus install than be easier to, and utilize its suitable thickness to guarantee excellent sealability; Simultaneously, because the sectional shape of supporting surface 5 is a flat U-shaped wide at the top and narrow at the bottom, thus not only have enough support forces, and be difficult for rolling.
