Embodiment 1

[0014] figure 1 is a structural schematic diagram of the self-locking sealing connection device of the present invention, in figure 1 Among them, the self-locking sealing connection device of the present invention includes a self-blocking knife-edge stud 1, a retaining ring 2, a steel ball compression sleeve 3, a locking steel ball 4, a spring 5, a washer 6, a looper connection nut 7, and a looper knife edge Take over 8. Its connection relationship is that the looper knife-edge adapter 8 is embedded in the looper connection nut 7, and the gasket 6 is placed between the self-blocking knife-edge stud 1 and the looper knife-edge adapter 8. The periphery of the self-blocking tight knife-edge stud 1 is provided with a looper connecting nut 7, and the outer end surface of the self-blocking tight knife-edge stud 1 is radially provided with a groove I, and the self-blocking tight knife-edge stud 1 and the looper connecting nut 7 pass through the thread connect. Several round holes ...

Embodiment 2

[0022] The structure of this embodiment is the same as that of Embodiment 1, except that the number of round holes provided on the looper connection nut 7 is six.

Abstract

The invention provides a self-locking seal connection device. A loop tool edge connection tube in the device is embedded into a loop connection nut, and a gasket is placed between a self-locking tool edge stud and the loop tool edge connection tube. The loop connection nut is arranged on the periphery of the self-locking tool edge stud, a groove I is radially formed in the outer end face of the self-locking tool edge stud, and the self-locking tool edge stud is connected with the loop connection nut in a threaded manner. A plurality of circular holes are uniformly formed in the radial end face of the loop connection nut, and locking steel balls are placed in the circular holes. A steel ball compression sleeve and a spring are arranged on the periphery of the loop connection nut, and a retaining ring is placed in the loop connection nut. Tool edge sealing is matched with self-locking, rapid connection can be realized, the purpose of self-locking is achieved by the locking steel balls, the spring and the steel ball compression sleeve, the device does not easily loose in workplaces such as vibration (shock) places, seal reliability at a joint can be kept for a long time, and the device is simple in structure and convenient to mount.

Description

technical field [0001] The invention belongs to the technical field of sealing devices, and in particular relates to a self-locking sealing connection device. The present invention is suitable for ultra-high vacuum (10 -6 ~10 -10 Pa), the sealing connection of pipelines under vibration or vibration environmental conditions, the use of self-locking can ensure the reliability of the sealing of the connection for a long time and very well. Background technique [0002] At present, most of the sealing connection methods use flanges, threads, clamps, etc., and the anti-loosening devices use spring washers and other methods. The reliability of the connection seal cannot be maintained for a long time, especially in some workplaces with frequent vibration (vibration), the seal connection is easy to cause loosening. Contents of the invention [0003] In order to solve the long-term sealing reliability of pipeline joints under ultra-high vacuum, vibration or vibration environment...
