Description

Ball-type embedded pipe joints with quick assembly and disassembly

This invention relates to a ball-type embedded pipe joint with quick assembly and disassembly, especially a pipe joint piping structure design used in piping engineering, which has the dual functions of high-level piping assembly and pipe withdrawal and disassembly; both in terms of parts cost and assembly time Analyzing the three major aspects of pipe withdrawal and disassembly, extremely high economic benefits and progress can be achieved.

The overall structure of this case includes: a pipe joint, a ball fitting, a spring and a sealing rubber ring; a first receiving groove is provided in the connection interface of the pipe joint head joint, and a ball insert is provided in the first receiving groove. The coupling piece and the spring piece, the spring piece is pushed against the ball fitting piece with a constant force, and a first slope provided in the first accommodation groove and a second slope provided on the ball fitting piece interfere with each other; In this way, when the connecting pipe is fitted into the connecting port, the second inclined surface of the ball fitting part will be pressed by the first inclined surface of the first receiving groove to shrink and tighten, forming a convergent tightening function, so that the ball can be tightened. The fitting piece is firmly embedded in the connecting pipe, enabling fast and stable connection in the piping project; in addition, through the plurality of balls provided on the outer wall of the ball fitting piece, the pipe joint is firmly fitted into the connecting pipe and at the same time, The connecting pipe also has the ability to rotate to effectively meet the functional requirements of piping construction.

If you need to withdraw and disassemble the connecting pipe, you only need to push against the ball fitting outside the protruding adapter, forcing the spring to compress so that the ball fitting returns and is loosely embedded in the connecting pipe, completing the quick withdrawal and disassembly of the connecting pipe. Tubes; achieve the high-level functions of quick and stable mutual fitting connection and rapid withdrawal and disassembly of tubes.

According to common knowledge, the connection between water pipes is mainly through pipe joints that are tightly connected between pipes. In order to avoid leakage at the connection between pipes and pipe joints, generally Adhesive will be coated on the outer wall of the pipe and the inner wall of the pipe joint respectively to adhere the pipe and the pipe joint so that the pipes can be firmly connected to each other and avoid water leakage.

Alternatively, screw-lock pipe piping may be adopted at a higher cost. In this method, a rubber ring is installed on the inner wall of the pipe joint, and then the pipe joint is locked on the pipe joint with a screw-lock tightening method, forcing The rubber ring is tightly pressed against the outer wall of the nozzle to reach between the nozzle and the pipe joint to complete the forced connection and prevent leakage.

However, there are many problems arising from the above conventional connection methods of takeover and management takeover; for example:

1. The use of adhesives to connect the nozzle and the pipe joint to each other is not only complicated in the construction process, but also unreliable. Once the nozzle and the pipe joint are adhered, if the nozzle path needs to be changed or changed during the construction process, the nozzle and the pipe joint are both It cannot be disassembled and reassembled. Both the pipes and pipe joints must be completely cut off and scrapped, and then the pipes and pipe joints must be reassembled. In addition to increasing the cost burden of piping accessories, the time and effort will be increased, making this kind of assembly impossible. Economical and inconvenient, not only does it not have environmental benefits, but it will also significantly increase construction costs.

2. After the pipe and pipe joint are fixedly connected by adhesive method, it will not take long for the adhesive to harden and age, which is prone to fragmentation and rupture. Once the pipe and pipe joint are impacted or vibrated by external force (such as : Earthquake shaking), the joint between the pipe and the pipe joint will inevitably cause leakage or even pipe breakage. The repair of these problems is currently the most important task in the repair of pipelines in hydropower projects. for tough questions.

3. Use the screw lock method and the rubber ring to tighten the connection between the pipe and the pipe joint. In addition to the high cost of the piping project, the rubber ring only has the effect of tightening the pipe and the pipe joint, and has no other fixing effect. Due to the design structure, once the nozzles and pipe joints are impacted or vibrated by external forces (such as earthquake shaking), the rubber rings are easily deformed due to displacement, resulting in micro-leakage problems; or the rubber rings in the construction piping installation are slightly out of place. If you are not careful, the rubber ring will be twisted, curled and torn when twisting and locking. These are the main factors causing leakage at the joint between the pipe and the pipe joint. They are also an important issue that needs to be solved urgently in this case.
