Description
Technical Field
The utility model belongs to the technical field of the pipe joint, concretely relates to PVC drain pipe joint structure.
Background
The PVC drain pipe is produced by using polyvinyl chloride (PVC) resin as a main raw material, adding a proper amount of a stabilizer, a lubricant, a filler, a toner and the like, performing extrusion molding through a plastic extruder and injection molding through an injection molding machine, and performing cooling, curing, sizing, inspection, packaging and other processes. The PVC drain pipe joint connects two or more sections of drain pipes through the adhesive for the water pipes, thereby being convenient for use in different occasions.
However, in practical use, the pipe diameters of the drain pipes have various specifications, and when the drain pipes are installed on the joints, and when the gaps between the drain pipes and the joints are large, once the usage amount of the adhesive is insufficient or uneven, the water leakage phenomenon of the drain pipes is easily caused. In addition, most of the sealing gaskets used in the existing PVC drain pipe joint are annular, and when the stress is uneven or the pressure is large, the phenomenon that the sealing gasket is damaged to cause untight sealing and water leakage is easy to occur.
SUMMERY OF THE UTILITY MODEL
The utility model provides a PVC drain pipe joint structure to solve the problem that current PVC connects easy the leaking.
In order to solve the technical problem, the utility model discloses a following technical scheme:
a PVC drain pipe joint structure comprises a joint main body (1), a joint (2) and a sealing sleeve (5), wherein the joint (2) consists of an outer ring (3) and an inner ring (4), and an annular partition plate (6) is arranged between the outer ring (3) and the inner ring (4); the sealing sleeve (5) consists of a cylindrical sleeve body (51) and a base (52), wherein the sleeve body is hollow; the sleeve body (51) is tightly attached to the outer surface of the inner ring (4), and the base (52) is tightly attached to the partition plate (6).
Further, the length of the inner ring (4) is 0.5-1 times of the length of the outer ring (3). The outer wall of the drain pipe is tightly attached to the outer ring through a water pipe adhesive; the outer surface of the inner ring is provided with a sealing sleeve which is tightly attached to the inner wall of the drain pipe, so that the lengths of the outer ring and the inner ring can be set to be the same or different according to requirements in design.
Further, the inner diameter of the sleeve body (5) is equal to the outer diameter of the inner ring (4).
Furthermore, the thickness of the sleeve body (51) is 0.8-6mm, and the length is the same as that of the inner ring (4).
Furthermore, the distance between the outer ring (3) and the inner ring (4) is the sum of the thickness of the sleeve body (51) and the thickness of the installed drain pipe, when the drain pipe is connected with the joint, the thickness of the sleeve body of the sealing sleeve can be prefabricated in advance to improve the installation efficiency and ensure the sealing effect due to the fact that the pipe diameters of the drain pipe are different, and if the thickness of the sleeve body is 1mm, 2mm, 4mm and other specifications, the sleeve body can be selected quickly according to different requirements when in use.
Further, the base (52) is U-shaped in cross section. The U-shaped section of the base has the advantages that when the joint is connected with the drain pipe, the drain pipe is inserted into the joint, and the U-shaped section of the base enables the edges on the two sides of the base to extrude the inner wall and the outer wall of the drain pipe, so that tightness of sealing is guaranteed.
Furthermore, the height of the U-shaped section of the base (52) is 3-6mm, the thickness of the base (52) is 0.5-1.2mm, and the thickness of the outer edge (53) of the base is 0.5-1.2 mm.
Furthermore, the included angle between the base (52) and the sleeve body (51) is 90-145 degrees. Because the base and the cover body form a certain angle, the annular space formed by the outer ring and the cover body is gradually reduced from outside to inside, so that when the drain pipe is inserted into the connector, the more the inner space is smaller, the base strengthens the extrusion of the drain pipe, thereby ensuring that the cover body and the drain pipe are sealed tightly, avoiding the leakage of water and improving the water leakage prevention performance.
Further, the sealing sleeve (5) is made of rubber.
The sealing sleeve (5) can be tightly attached to the outer surface of the inner ring by using a common water pipe adhesive.
The utility model has the advantages that: this novel joint design has used the design of outer loop and inner ring, then is equipped with the seal cover on the inner ring surface, can ensure through the use of seal cover that closely laminating between joint and the drain pipe effectively prevents to leak. The utility model discloses an interface design can be applied to various types of joints.
