Abstract
The utility model discloses a kind of lips and carve RunddichtringO, belong to seal ring technical field, comprise and carve RunddichtringO body, also second lip of seal is had additional in described body lip position, described body lip and second lip of seal form lips and carve type structure, form an inclination V-type mouth between described body lip and second lip of seal, and a side of described inclination V-type mouth is convex surface, opposite side is concave surface, and convex surface and concave surface are level and smooth second dervative model face; The utility model effectively by single lip seal not exclusively and the water of seepage seals again, can reach sealing effect better due to the design having double-lip; Meanwhile, owing to there being double-lip design, effectively the resistance of single lip being shared on 2 lips, be more beneficial to installation, when effectively overcoming installation, easily moved the technical barrier of rolling.
Description
Technical field
The utility model relates to a kind of rubber seal, particularly relates to a kind of reinforced concrete push pipe bell socket rubber seal.
Background technique
At present, in known technology, when the seal ring of conventional push pipe is installed, easily move rolling or leak (problem of poor sealing).Long-term water-stop is the most difficult and most important technical requirements of reinforced concrete push pipe bell socket, and addressing this problem also is one of the most key technology in reinforced concrete push pipe market.
As shown in Figure 1, Fig. 1 product is the existing reinforced concrete push pipe wedge-type seal circle commercially used, and owing to only using a seal lip, product in use there will be poorly sealed, the problem that the life-span is not grown; Simultaneously owing to only having single seal lip, mobile rolling or poor sealing during installation, is caused to occur seepy question because resistance is excessive.
Model utility content
The utility model, in order to overcome the deficiencies in the prior art, being installed requirement that is stable and good airproof performance to meet mixed earth push pipe bell socket seal ring, being proposed a kind of lips wedge-type seal circle.
The utility model is achieved through the following technical solutions: lips carve RunddichtringO, comprise and carve RunddichtringO body (1), second lip of seal (2) is also had additional in described body (1) lip position, described body (1) lip and second lip of seal (2) form lips and carve type structure, form an inclination V-type mouth (3) between described body (1) lip and second lip of seal (2).
Further, after numerical simulation, a side of described inclination V-type mouth (3) is convex surface (30), and opposite side is concave surface (31); Convex surface (30) and concave surface (31) are level and smooth second dervative model face.
Owing to have employed said structure, the utility model compared with prior art, there is following beneficial effect: sealing position is designed to carve type double-lip, it is less that its wedge-shaped design installs resistance, is designed to double-lip sealing simultaneously, effectively shared by the resistance of single lip on 2 lips, more be beneficial to installation, easily move the problem of rolling or the poor sealing that leaks when effectively overcoming installation, sealing effect is more of a specified duration, and the time is longer; The design of two seal lips also solves the phenomenon of the easily mobile rolling when an assembling lip assembling, the size design of lips wedge-type seal circle lip height exceeds 10-20% than the socket of reinforced concrete push pipe, effectively make use of rubber elasticity sealing function, serve the effect of height permanent seal.
Accompanying drawing explanation
Fig. 1 carves RunddichtringO schematic cross-section in prior art;
Fig. 2 is that the utility model lips carve RunddichtringO schematic cross-section.
Embodiment
Below in conjunction with the drawings and the specific embodiments, the utility model is described further.
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 2, lips carve RunddichtringO, comprise and carve RunddichtringO body 1, second lip of seal 2 is also had additional in described body 1 lip position, described body 1 lip and second lip of seal 2 form lips and carve type structure, form an inclination V-type mouth 3 between described body 1 lip and second lip of seal 2, a side of described inclination V-type mouth 3 is convex surface 30, and opposite side is concave surface 31; , after numerical simulation, convex surface 30 and concave surface 31 are level and smooth second dervative model face.
When the utility model is installed, the flat direction of lips wedge-type seal circle is arranged on pipeline holds in seal groove, lips seal for the upper wall withstanding pipeline socket, because the design having double-lip effectively by single lip seal not exclusively and the water of seepage seals again, can reach sealing effect better; Meanwhile, owing to there being lips design, effectively the resistance of single lip being shared on 2 lips, be more beneficial to installation, when effectively overcoming installation, easily moved the technical barrier of rolling.
Claims (2)
1. lips carve RunddichtringO, comprise and carve RunddichtringO body (1), it is characterized in that, second lip of seal (2) is also had additional in described body (1) lip position, described body (1) lip and second lip of seal (2) form lips and carve type structure, form an inclination V-type mouth (3) between described body (1) lip and second lip of seal (2).
2. lips according to claim 1 carve RunddichtringO, it is characterized in that, a side of described inclination V-type mouth (3) is convex surface (30), and opposite side is concave surface (31).
