Abstract
The utility model discloses an irregularly-shaped seal ring which comprises a seal ring body; an extending part is arranged on at least one side of the seal ring body along the axial lead direction thereof; and the extending part narrows gradually from the joint to the free end. The irregularly-shaped seal ring has the advantage that when the seal ring is mounted in a tap water pipe component, the contact area of the seal ring and a water pipe is greatly increased due to the arrangement of the extending part, thereby improving the sealing performance of the seal ring and efficiently preventing water from leaking. The inner side surface of the extending part is slightly inclined outward. When the seal ring is mounted on the water pipe, the extending part is hardly in contact with the water pipe; the resistance force of the seal ring and the wall of the water pipe is smaller; and the installation is more convenient. When a pipe joint acts on the seal ring, the extending part deforms certainly, so that the extending part abuts against the water pipe to achieve the sealing effect.
Description
Technical field
The utility model relates to a kind of fixing ring, especially relates to the running water pipe assembly of a kind of fixing ring and use sealing circle.
Background technique
Joint between the running water pipe adopts O-ring seals to seal usually, and the cross section of O-ring seals is circular.The running water pipe assembly comprises pipe joint and water pipe, pipe joint is pressed on the water pipe by the mould card of special use, between pipe joint and water pipe, adopt the O RunddichtringO to seal, the structures shape of O RunddichtringO its with water pipe between only to contact be line contact or less face contact, when hydraulic pressure is big, the O RunddichtringO possibly can't accomplish to seal fully, and the joint still has a spot of water and oozes out between water pipe and the pipe joint.
Summary of the invention
Technical problem to be solved in the utility model provides the more excellent fixing ring of a kind of sealability and uses the running water pipe assembly of sealing circle.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of fixing ring, comprise the seal ring body, described seal ring body is provided with extension part along at least one side of its direction of axis line, and the joint of described extension part to free end is narrowed down gradually by wide.
Described extension part inner side surface is outward-dipping slightly.
A kind of running water pipe assembly, comprise water pipe and pipe joint, described pipe joint is connected on the described water pipe, be provided with described fixing ring between described pipe joint and the described water pipe, described fixing ring comprises the seal ring body, described seal ring body is provided with extension part along at least one side of its direction of axis line, and the joint of described extension part to free end is narrowed down gradually by wide.
Described extension part inner side surface is outward-dipping slightly.
Compared with prior art, advantage of the present utility model is when seal ring is installed in water pipe and the pipe joint, extension part on the seal ring increases the area of contact between seal ring and the water pipe greatly, improved the sealability of seal ring, the seepage of joint between effectively anti-water stopping tube and the pipe joint.
The extension part inner side surface is outward-dipping slightly.When seal ring was installed to water pipe, extension part did not contact with water pipe substantially, and the resistance ratios of seal ring and water wall is less, installed more convenient.After the extension part extruding of pipe joint to seal ring, extension part generation deformation makes extension part near water pipe, reaches good sealing effect.
