Positive and negative pressure experiment tank with quick locking mechanism

Abstract

The invention discloses a positive and negative pressure experiment tank with a quick locking mechanism, which comprises a tank body and a gate, one-dimensional clamping bow mechanisms and two-dimensional clamping bow mechanisms are arranged at the joint of a tank body opening flange and a gate flange, and at least four two-dimensional clamping bow mechanisms are arranged along the circumferential direction of the opening of the tank body at intervals. The one-dimensional clamping bow mechanism is arranged between the two-dimensional clamping bow mechanisms, the one-dimensional clamping bow mechanism comprises a first driving device and a first C-shaped clamping bow, an opening of the first C-shaped clamping bow is used for clamping the edges of the opening flange and the gate flange, and the first driving device drives the first C-shaped clamping bow to move in the radial direction; the two-dimensional clamping bow mechanism comprises a second driving device, a third driving device and a second C-shaped clamping bow, an opening of the second C-shaped clamping bow is used for clamping the edges of the opening flange and the gate flange, the second driving device drives the second C-shaped clamping bow to move in the radial direction, and the third driving device drives the second C-shaped clamping bow to move in the axial direction. The tank gate locking device can complete rapid locking of the tank gate, manual locking is not needed, the operation efficiency is high, and locking is reliable.

Description

technical field [0001] The invention relates to a pressure test tank, in particular to a positive and negative pressure test tank with a fast locking mechanism. Background technique [0002] In experiments with environmental simulation requirements, it is necessary to use vacuum tanks to obtain the corresponding environment, so that the internal environment meets the experimental requirements. In most cases, it is always desirable to obtain a negative-pressure vacuum environment. For example, the Chinese patent with the publication number CN113671266A discloses a wide-band vacuum microwave anechoic chamber, which has a vacuum tank and a vacuum seal at one end of the vacuum tank. Flange, using the airtight fit between the vacuum head flange and the vacuum tank body, the vacuum environment can be formed after the inside is evacuated. Another example is that the Chinese patent with the publication number CN213147859U discloses a simple vacuum tank, comprising a tank body, the ...
