Description

[0001] A Packing for Pipes Connection [0002]

The present invention relates to a tubular connection packing having improved sealing strength, which is used when connecting ends of a tubular body and a tubular body to each other inside a tubular connector.

The watertight packing connecting member is formed integrally with an outer surface watertight horizontal connecting ring on an outer surface of a watertight packing body formed in a trapezoidal shape and a central cutout groove is formed to open downward inside the watertight packing body, The watertight horizontal connection ring is formed with watertight ridges and watertight portions on both sides of the outer circumferential surface thereof and one or more curved watertight connection protrusions are formed therebetween to form a tightly packed watertight packing. The watertight stone formed on both side edges of the outer peripheral surface of the outer watertight horizontal connection ring is folded outward to be connected to the watertight portion so as to have a double sealing force, The projecting portion comes into contact with the inner circumferential surface of the connecting tube and is compressed and attached to the inner circumferential surface of the connecting tube, Adhered to and not as a hermetically sealed so as to also enhance tight adhesion effect is intended to provide a better seal for tube connection.

Generally, a sewer pipe, a collecting pipe and a drain pipe forming a flow path for circulating a fluid (sewage) is formed of a synthetic resin material such as polyethylene (PE) or polyvinyl chloride (PVC) A double-walled tube formed by integrally joining outer tubes formed with recesses is mainly used.

The double wall tube extends in the axial direction through a pipe connecting member such as a socket, a connecting pipe or a connecting pipe, and a packing is used between the double wall pipe and the connecting member to ensure watertightness of the pipe connecting.

The conventional packing has a ring-shaped packing body portion inserted into a groove of a double walled pipe, and a pair of pipe-shaped body portions extending perpendicularly from the outer end of the packing body portion to be positioned between the double walled pipe and the connecting member, And a watertight extension portion in which a projection is protruded.

However, in the conventional double wall pipes, if the spacing of the double wall pipes is larger than the width of the packing body portion, the sealing force tends to be leaked due to the sealing force, and if the spacing of the double wall pipe is smaller than the width of the packing body portion, .

Conventionally, as a conventional packing member, there have been proposed a packing member of Japanese Patent Application Laid-Open No. 10-1998-3129 (packing member for watertight connection of a pipe body) and a novelty 20 -205378 (elastic rubber ring for watertight connection to a pipe body) are known. The former is formed by forming a brave on the horn of each triangular body formed in a triangular shape and the latter is formed by forming a projection on both ends of the outer surface of the body of a flat plate type. Since these are used to be sandwiched between the body and the tube, Is greatly reduced.

Another conventional coupling tube is known from 1999 Utility Model No. 20-157456.

This makes it possible to provide a joint pipe that can cut the tube insertion hole so as to hold the tube to be inserted and press the tube to join the tube, and it is easy to assemble the tube by the simple structure of the screw connection, It is necessary to form a cut end at the end of the joint pipe having an enemy diameter so as to insert the tube into the tube and to seal the tightening tube so that the tube is branched by pressing the cut end A structure related to the joint pipe is disclosed.

However, since the joint pipe according to the related art has no variable structure in the joint pipe, it is possible to prevent uneven settlement in the soft ground, expansion and contraction due to thermal expansion, overload caused by dead load and live load, etc. The impact can not be absorbed. Therefore, when a load greater than the rigidity of the joint portion acts, there is a problem that breakage occurs in the joint pipe or the pipe portion.

In order to solve this problem, Patent Registration No. 10-0915524 (a double-walled tubular sound tube) is known.

This is because the anti-slip ring and the packing are provided with a protrusion on the inner surface of the main ring (or ring tube) And the slits are introduced into the grooves formed between the projections and the projections on the outer periphery of the tubular body.

However, this is because the slip-resistant ring and the protrusions formed on the packing are formed so that the protruding pieces are introduced into the grooves formed on the outer periphery of the tubular body to seal the tubular body, so that the sealing ability is significantly lowered and the tubular bodies connected to each other are not firmly restrained.

Another conventionally known method for connecting the tubular body is disclosed in Korean Utility Model Registration No. 20-0416913 (tubular connecting packing).

The packing has a watertight extension portion horizontally held on the outer periphery of a packing body portion held in a vertical ring shape, a cutout groove opened to the lower side is formed at an inner center of the packing body portion, And a plurality of protrusions formed on the outer surface of the watertight extension portion held horizontally, wherein the protruding portions formed on the outer surface of the watertight extension portion are in contact with the inside of the connection tube .

However, this is because the wing element formed on the inner surface of the packing body portion is connected to the outer circumferential surface ring forming the tube body, and the protrusions formed on the outer surface of the watertight extension portion are connected to the inside of the connector tube. However, There is a possibility that the supporting force, the sealing force and the adhesion force may be deteriorated by the impact.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a tubular connection packing improved in sealing adhesion so as to overcome the above-mentioned conventional problems.

The present invention is characterized in that an outer surface watertight horizontal connection ring is integrally formed on an outer surface of a watertight packing body formed in a trapezoidal shape and a central cutout groove is formed to open downward inside the watertight packing body, The present invention provides a tube connection packing having improved tight sealing performance, characterized in that a watertight stone and a watertight portion are formed at both side edges of an outer circumferential surface of the ring and at least one curved watertight connection protrusion is formed therebetween to form a tightly sealed watertight packing It has its purpose.

Another object of the present invention is to provide a watertight horizontal connection ring which is formed by joining a tightly sealed tightly packed waterproof packing to an annular groove of a tubular body and inserting the sealed tightly watertightly sealed packing into the tubular body, And the curved watertight connection protrusions formed therebetween come into contact with the inner circumferential surface of the connection tube and are compressed and adhered to each other so that they are strongly adhered to and supported by the inner surface of the connection tube, And to provide a packing for connecting a tube having improved adhesion.
