| titleOfInvention | Multi-cavity to single-cavity universal joint |
| abstract | The utility model relates to a multicavity changes single chamber universal joint, wherein, set up first drainage hole in the single chamber connects, and the multicavity connects the center and sets up second drainage hole, and first, second drainage hole passes through the inner tube butt joint intercommunication, constitutes the second cavity between inside and outside pipe. The right end of the multi-cavity joint is uniformly provided with a plurality of horizontal sensor grooves along the circumferential direction of the second drainage hole, and the left ends of the sensor grooves are communicated with each other through annular grooves formed in the multi-cavity joint. The disc is integrally and fixedly arranged on the outer tube, a first cavity is formed in the disc, a center hole for communicating the first cavity with a second cavity is formed in the middle of the disc, and a water blocking film is fixed on the position, located at the center hole, of the outer end face of the disc. The inner edge of the disc is also provided with a communicating hole communicated with the annular groove. The utility model discloses in can satisfying the negative pressure drainage device use, the multicavity changes the user demand in single chamber, realizes real-time supervision pressure and reaches the purpose of in time discovering equipment trouble, prevents that liquid from blockking up equipment and leading to the treatment failure or delay. |
