Description

Technical Field

[0001] This utility model relates to the field of PP pipe technology, specifically a modified PP pipe with a quick-connect sealing function. Background Technology

[0002] PP pipe (polypropylene pipe) is a pipe made of polypropylene material. It has the characteristics of being non-toxic, corrosion-resistant, high temperature resistant, lightweight, and easy to install. It is widely used in construction, agriculture, industry, and municipal fields. However, the existing modified PP pipes are inconvenient to connect during use, and the joints have poor sealing. This means that the joints of the modified PP pipes need to be sealed and repaired frequently during use. Therefore, a new type of pipe is needed to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a modified PP pipe with a quick-connect sealing function to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a modified PP pipe with a quick-connect sealing function, comprising a first pipe body, a second pipe body, a connecting threaded ring, a compression spacer ring, a second rubber sealing gasket, and a threaded insertion end. The ends of the first pipe body and the second pipe body are sealed together. The connecting threaded ring is fixedly installed at one end of the first pipe body and the second pipe body. The threaded insertion end is fixedly connected to the other end of the first pipe body and the second pipe body. The threaded insertion end is adapted to the threaded insertion groove inside the connecting threaded ring. The compression spacer ring is fixedly installed on the inner side of the end of the first pipe body and the second pipe body where the threaded insertion end is located. The second rubber sealing gasket is located on the outer end of the compression spacer ring.

[0005] Preferably, the outer end of the threaded insertion end is fixedly connected to a compression end.

[0006] Preferably, the extrusion end is inserted into the interior of the connecting threaded ring, and a first rubber sealing gasket is extruded and secured between the outer edge of the extrusion end and the connecting threaded ring.

[0007] Preferably, the outer end face of the connecting threaded ring is in extrusion contact with the second rubber sealing gasket, and the connecting threaded ring extrudes and fixes the second rubber sealing gasket between the extrusion spacer rings, and the outer diameter of the connecting threaded ring is the same as that of the extrusion spacer ring.

[0008] Preferably, after the threaded insertion end is inserted into the interior of the connecting threaded ring, auxiliary clamping sealing rings are provided on both the outer sides of the connecting threaded ring and the extrusion spacer ring, and fixing bolts are evenly threaded and inserted between the two sides of the auxiliary clamping sealing rings.

[0009] Preferably, a rubber sealing gasket is provided between the auxiliary clamping sealing ring, the connecting threaded ring, and the compression spacer ring for secure clamping.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This utility model significantly simplifies the pipe connection process and improves installation efficiency by using a standard threaded plug end and a connecting threaded ring. The triple seal works synergistically after connection, forming a tight leak-proof system. This solves the problems of poor sealing at the joint and the need for frequent seal repairs. It significantly improves the long-term sealing reliability of the interface under high pressure, corrosive fluids, or temperature changes. The connection is firm and reliable, preventing loosening. The threaded connection itself provides a certain mechanical locking force, and the auxiliary clamping sealing ring is powerfully locked by bolts, tightly binding the connected threaded ring and the compression spacer ring together. This effectively prevents loosening of the threaded connection due to pipe vibration, water hammer effect, or thermal expansion and contraction, greatly improving the mechanical strength and long-term stability of the interface. Therefore, this pipe body achieves rapid installation through threaded plug connection and innovatively combines a triple sealing structure with an external bolt locking anti-loosening structure, solving the key problems of inconvenient PP pipe connection, poor sealing, and easy loosening and leakage in existing technologies.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3 This utility model provides an embodiment of a modified PP pipe with a quick-connect sealing function, comprising a first pipe body 1, a second pipe body 3, a connecting threaded ring 6, a compression spacer ring 7, a second rubber sealing gasket 8, and a threaded insertion end 9. The ends of the first pipe body 1 and the second pipe body 3 are sealed together. The connecting threaded ring 6 is fixedly installed at one end of the first pipe body 1 and the second pipe body 3. The threaded insertion end 9 is fixedly connected to the other end of the first pipe body 1 and the second pipe body 3. The threaded insertion end 9 is adapted to the threaded insertion groove inside the connecting threaded ring 6. The compression spacer ring 7 is fixedly installed on the inner side of the end of the first pipe body 1 and the second pipe body 3 where the threaded insertion end 9 is provided. The second rubber sealing gasket 8 is provided on the outer end of the compression spacer ring 7.

[0018] The outer end of the threaded insertion end 9 is fixedly connected to the compression end 10.

[0019] The extrusion end 10 is inserted into the interior of the connecting threaded ring 6, and a first rubber sealing gasket 5 is provided between the outer edge of the extrusion end 10 and the connecting threaded ring 6 for compression and locking.

[0020] The outer end face of the connecting threaded ring 6 is in contact with the second rubber sealing gasket 8 by compression, and the connecting threaded ring 6 compresses and fixes the second rubber sealing gasket 8 between the compression spacer rings 7. The outer diameters of the connecting threaded ring 6 and the compression spacer rings 7 are the same, which can fully compress and seal the second rubber sealing gasket 8.

[0021] After the threaded end 9 is inserted into the inside of the connecting threaded ring 6, auxiliary clamping sealing rings 2 are provided on both sides of the connecting threaded ring 6 and the extrusion spacer ring 7. Fixing bolts 4 are evenly threaded and inserted between the two sides of the auxiliary clamping sealing rings 2, which can achieve full clamping, fitting, locking and sealing treatment.

[0022] A rubber sealing gasket is provided between the auxiliary clamping sealing ring 2 and the connecting threaded ring 6 and the compression spacer ring 7 to assist in a full seal.

[0023] Working principle: The threaded insertion end 9 of the first pipe body 1 is screwed into the connecting threaded ring 6 of the second pipe body 3. The pipe bodies are initially connected through thread engagement. During tightening, the pressing end 10 at the end of the threaded insertion end 9 is inserted into the connecting threaded ring 6 and presses against the first rubber sealing gasket 5, forming the first radial seal to prevent fluid leakage along the pipe wall gap. When the thread is fully tightened, the end face of the connecting threaded ring 6 presses against the second rubber sealing gasket 8, forming the second axial end face seal. The pressing spacer ring 7 has the same outer diameter as the connecting threaded ring 6, ensuring that the pressure is evenly transmitted to the sealing gasket 8 and enhancing the joint sealing performance. An auxiliary clamping sealing clip is fitted on the outside of the connection after the connection is completed. Ring 2 covers the joint between the threaded ring 6 and the compression spacer ring 7. The auxiliary clamping sealing ring 2 is evenly tightened by the fixing bolt 4, which applies radial pressure to the joint of the pipe body, further compressing the internal rubber sealing gasket and providing a third layer of leakage protection. The locking of the ring 2 can offset the risk of thread loosening caused by pipe vibration and thermal expansion and contraction. The triple sealing effect makes the sealing effect better after docking. The first seal is the gasket 5, which blocks the thread gap. The second seal is the gasket 8, which seals the pipe end contact surface. The third seal is the auxiliary clamping sealing ring 2, which compensates for the sealing attenuation during long-term use. The triple design ensures that the interface maintains long-term airtightness under high pressure and corrosive environment.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
