Embodiment 1
[0023] The sealing ability verification device of the sealing ring in this implementation is as follows: Figure 1 to Figure 4 As shown, the two ends of the base 4 respectively support the vacuum tank 1 and the push rod assembly 3 . The vacuum tank body 1 is composed of an inner layer 1-1 and an outer layer 1-2 with one end open. The opening of the outer layer 1-2 has a flange ring 1.1, and an outer flange 1.2 sealed and fixedly connected thereto is installed by a fastener. The opening of the inner layer 1-1 through the neck of the bottle has an inner flange 6, and the outer end surface of the inner flange 6 has an embedding groove for installing a test sealing ring 7.
[0024] The inner hole of the outer flange 1.2 is welded and hermetically connected to one end of the sealing bellows 2 inserted therein, and the other end of the sealing bellows 2 is sleeved outside the pressure applying ring 13 and is welded and sealed to it. The inner end of the pressure applying ring 13 h...

The invention relates to a device for verifying the sealing capability of a sealing ring, and belongs to the technical field of air tightness tests. The device comprises a vacuum tank body and a push rod assembly which are respectively supported at two ends of a base, wherein the vacuum tank body is composed of an inner layer and an outer layer with one open end, an outer flange plate fixedly connected with the opening of the outer layer in a sealing mode is installed on the opening of the outer layer, and an inner flange embedded with a test sealing ring is arranged on the opening of the inner layer; an inner hole of the outer flange plate is in sealing connection with one end of a sealing corrugated pipe, the other end of the sealing corrugated pipe is in sealing connection with a pressure applying ring, and the inner surface of the pressure applying ring is matched with the end face of the inner flange embedded with the test sealing ring; and the push rod assembly is provided with a telescopic push rod, the end, which is close to the vacuum tank body, of the push rod is connected with a force application platform, and the force application platform is provided with an annular acting end acting on the inner flange through the pressure applying ring. According to the invention, after the vacuum interlayer space is vacuumized, the sealing performance verification data of the test sealing ring in the dynamic butt joint in the vacuum environment can be conveniently obtained by means of a corresponding test instrument.
Description
technical field [0001] The invention relates to a sealing ability verification device of a sealing ring, in particular to a device for verifying the sealing ability of a sealing ring in a dynamic butt joint form in a vacuum environment, and belongs to the technical field of air tightness testing. Background technique [0002] Sealing rings installed on various mechanical equipment need to perform a sealing function under specified temperature, pressure, and different liquids and gases in a static or moving state. However, the sealing effect of the sealing ring is affected by many factors such as material, hardness, compression, size, shape, and shape of the sealing groove. For example, one of its typical operating conditions is: in a vacuum environment, it is necessary to establish a channel to communicate with the atmosphere. The channel is connected through a dynamic butt joint, and the connection is sealed by pressing the sealing ring. [0003] As far as the applicant kn...
