Description

Pipe connection sealing structure and sealing ring

Technical Field

The utility model relates to a pipe connection technical field specifically is a pipe connection seal structure and sealing washer.

Background

The water pipe is the pipeline that supplies water, and whole water supply system all is formed by many water piping connection, and common operation during water piping connection is the socket and the bellmouth of two pipes directly pegged graft, and the sealing washer is installed to grafting department and is guaranteed the leakproofness, and traditional sealing washer is compressed tightly between two bellmouths, may have ageing after using through a period, or the bell and spigot warp and causes the clearance increase, may appear the problem of leaking.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem that current sealing washer department caused the leakage easily, the utility model provides a pipe connection seal structure, it can effectively guarantee the leakproofness, the phenomenon of leaking can not appear.

The technical scheme of the groove is as follows: the utility model provides a pipe connection seal structure, its includes pipeline socket and pipeline bellmouth, the pipeline socket with pipeline bellmouth clearance joint and junction install the sealing washer, a serial communication port, pipeline socket outer wall or pipeline bellmouth inner wall is seted up flutedly, the sealing washer install in the recess, the inside hollow setting of sealing washer just moves towards the through-hole has been seted up to the one side in the outside of recess.

The sealing ring is further characterized in that the radial section of the sealing ring is a hollow ellipse;

the through holes are uniformly spaced to form a circle;

the end part of the pipe bell mouth is provided with an outward flaring, and the end part of the pipe socket is provided with an inward closing-in.

The sealing ring comprises a sealing ring body and is characterized in that a through hole is formed in one side of the sealing ring body, and the radial section of the sealing ring is hollow and oval.

The device is further characterized in that the through holes are evenly provided with a circle at intervals.

Adopt the utility model discloses afterwards, after the pipeline socket and the pipeline bellmouth of two pipelines are connected, logical income water in the pipeline, because seted up the through-hole on the sealing washer, water can be along the through-hole get into in the sealing washer, expand the sealing washer, make closely laminating between its and the pipe wall, guaranteed the leakproofness, moreover when water pressure is high more, the leakproofness is better, the phenomenon of leaking can not appear.

Detailed Description

See fig. 1, fig. 2, fig. 3 shows, a pipe connection seal structure, it includes pipeline socket 1 and pipeline bellmouth 2, sealing washer 3 is installed to 2 clearance connections of pipeline socket 1 and pipeline bellmouth and junction, and recess 4 has been seted up to 1 outer wall of pipeline socket or 2 inner walls of pipeline bellmouth, and this embodiment is for seting up in the recess 4 of 1 outer wall of pipeline socket, and sealing washer 3 sets up in recess 4, and the inside hollow setting of sealing washer 3 just offers the through-hole 5 that the round was evenly arranged towards the one side in the outside of recess 4.

The end part of the pipeline bellmouth 2 is provided with an outward flaring, and the end part of the pipeline socket 1 is provided with an inward closing-in, so that the plugging is convenient.

During the installation, adorn earlier sealing washer 3 in the recess of pipeline socket 1, then insert pipeline socket 2 with pipeline socket 1 in, 2 inner wall cards of pipeline socket are inboard in recess 4, then lead to water, and water gets into through the clearance of junction, enters into sealing washer 3 by through-hole 5 in, struts sealing washer 3 from the ellipse that originally and finally is close to be circular, and tight support pipe inner wall realizes sealedly.

The following is to the utility model discloses a detailed comparison is made with conventional sealing washer to the sealing washer.

As shown in fig. 4, the conventional sealing ring is placed in the groove, the socket is sleeved outside the socket to compress the sealing ring, the sealing ring achieves the sealing purpose by using the elasticity of rubber, the shape of the sealing ring is O-shaped, the sealing ring has two types of hollow and solid, the diameter of the sealing ring is d, the depth of the groove is h, the design gap between the socket and the socket is delta, the allowed maximum gap between the socket and the socket is delta', the pre-compression ratio of the sealing ring is (d- (delta + h))/d, and the effect is best when the compression ratio is 20% -50%, taking a PCCP pipe as an example: d is 20mm, the depth h of the groove is 10mm, the designed clearance delta is 2mm, and the pre-compression ratio is 40%. In the long-term use process of the pipeline, the pipeline is deformed under the action of various external force factors, the gap between a socket and a spigot is enlarged, the sealing effect is poor, and when the gap delta > (d-h) is formed, the sealing is failed, taking a PCCP pipe as an example: the seal failed when Δ' > 10 mm.

As shown in figure 5, the sealing ring of the utility model is arranged in the groove, the stability of the sealing ring is better than that of O-shape when the sealing ring is installed in an oval shape, the sealing ring can not be damaged because the sealing ring is overturned and ejected out of the groove, the bell mouth is sleeved outside the socket, the chord lengths of the oval sealing ring are respectively a and b (a is more than b), the depth of the groove is h, the design gap between the bell mouth and the socket is delta, and the allowable maximum gap between the bell mouth and the socket is delta'; liquid is introduced into the pipeline and enters the hollow cavity of the sealing ring through the through hole in the sealing ring, when the deformation delta is increased in the using process of the pipeline, the ellipse is gradually deformed into an O shape under the action of internal pressure, the O shape diameter d = (2 pi x b +4 (a-b))/pi is shown, the parameters of the ellipse, namely b =10mm, a =20mm are taken as examples, d =32.7mm, and when the groove depth h is also 10mm, the maximum allowable gap delta' is increased from 10mm to 22.7mm, so that the reliability of the pipeline is greatly improved.
