Technical Field
The invention relates to a drain pipe connector, in particular to a connector of an HDPE winding pipe.
Background
HDPE (high Density polyethylene) refers to a highly crystalline, non-polar thermoplastic resin. The HDPE winding pipe is a buried drain pipe mainly used for municipal works, buildings, residential quarters and factories. Its advantages are simple process, long service life and high compression strength. When the HDPE winding pipe leaves a factory, the HDPE winding pipe generally has a fixed length; the required length of the connecting rods needs to be connected on site by adopting a manual method according to actual requirements.
In the prior art, chinese patent No. ZL2014103650853 discloses a socket joint, which is a connection winding pipe joint. The pipe joint comprises male plug and female plug two parts the inside of female plug is equipped with the sealing strip, forms the perk portion at the tip of sealing strip, and the perk portion is towards the direction of intaking. The male plug is inserted into the female plug, and the inserting end of the male plug forms a taper; the inner ring of the female connector is provided with a sealing strip, and when the male plug is inserted, the sealing strip is tightly attached to the outer wall of the tapered insertion port. According to the plug in the prior art, the material is inserted into the PVC winding pipe to complete installation. However, since there is only one sealing strip, leakage is likely to occur at the sealing portion of the pipe joint once deformation occurs after the pipe joint is subjected to vehicle expansion.
In addition, in the prior art, a pipe joint is often connected by electric melting. The method is characterized in that an electric fuse is arranged on the outer surface of a male connector of two HDPE winding pipes, after a male connector (or called a connecting plug) is inserted into a female connector (a connecting socket), the matching surface of the male connector and the female connector is made into appearance by adopting a power-on method, and the connecting connectors are firmly connected after being cooled. However, the electric melting method has good effect, but requires electric heating equipment in the construction site, which is inconvenient.
The invention is an improvement of the adapting plug, solves the problem that the water pipe is easy to leak after the HDPE winding pipe in the prior art is connected, and is very convenient to construct. When in use, no extra tool is needed, and the problem of inconvenient field installation of workers in the process of connecting HDPE winding pipes is solved.
Disclosure of Invention
The invention aims to provide a connector of an HDPE winding pipe, which is fast and convenient to install and is not easy to leak.
In order to achieve the above purpose, the solution of the invention is: the utility model provides a connector of HDPE winding pipe, includes plug, socket and sealing washer, its characterized in that: the socket comprises a shell with an embedded structure and a sealing ring matched with the embedded structure, and the socket and the plug are respectively fixed at one end of the HDPE winding pipe; the socket embedded structure is a gear-shaped mounting groove which is used for fixing a sealing ring; the outer side surface of the sealing ring is provided with a gear-shaped bulge matched with the inner wall of the socket; the inner side surface of the sealing strip is provided with a convex strip with a special-shaped section.
The mounting groove divide into: the front end mounting groove, the middle mounting groove and the rear end mounting groove are formed in the front end mounting groove; the number of the rear end mounting grooves is different from that of the front end mounting grooves, and the sealing rubber is prevented from being reversely mounted.
The middle mounting groove is provided with two large gear bulges.
The number of the rear end mounting grooves is larger than that of the front end mounting grooves.
The special-shaped convex strip consists of a lip and a cutting edge, the bottom is called the lip, the end part is a cutting edge, and the cutting edge is gradually widened from the lip to the lip; the tip blade of sealing strip forms the perk portion, and the perk portion is towards the direction of intaking, forms sealedly under the effect of rivers.
When the HDPE winding pipe is used, one end of the flat opening of the connecting socket with the rubber water seal is connected with the HDPE winding pipe, and the other HDPE winding pipe is inserted into the connecting socket with the rubber water seal to form the connection of the HDPE winding pipe. In a free state, the inner diameter of the rubber water seal lip is smaller than the diameter of the winding pipe, and a certain interference magnitude is achieved. After the installation, the interference pressure of the rubber water seal lip and the pressure of water flow generate radial pressure on the HDPE winding pipe. Under the action of water pressure and radial pressure in the pipe, a 'meniscus' is formed between the HDPE winding pipe inner pipe and the rubber water seal to prevent water flow from overflowing and achieve the sealing effect. The rubber water seal has a design of two layers of sealing strips, has double sealing effects, and can ensure that the sealing effect is better.
The invention is formed when leaving factory, has simple structure, convenient and rapid subsequent installation, is easy to install in construction site, and does not need additional installation tools.
