Technical Field
The invention relates to the field of quick connection leak detection, in particular to a device for quick connection leak detection of a membrane component.
Background
The existing membrane component leakage detection adopts an air source, whether leakage points exist in products is detected through a bubble method, the membrane component and the air source are connected differently, leakage detection modes of different manufacturers are different, and therefore the membrane component is low in detection efficiency and low in operability of personnel.
Disclosure of Invention
The invention aims to solve the technical problem of overcoming the defects in the prior art and provides a device for quick connection and leakage detection of a membrane component.
The invention relates to a device for detecting leakage of a membrane assembly in quick connection, which is realized by the following technical scheme and comprises a bolt shaft, a tightness adjusting mechanism, a prepressing mechanism, a spacing mechanism, a fixing mechanism, a foolproof mechanism and a tension sealing ring, wherein the bolt shaft is sequentially sleeved with the fixing mechanism, the foolproof mechanism and the tightness adjusting mechanism from the top end to the tail end, the prepressing mechanism is sleeved outside the foolproof mechanism, the bolt shaft and the fixing mechanism sleeved at the top end of the bolt shaft are fixedly connected through a bolt, the fixing mechanism is of a ring structure, the peripheral surface of the fixing mechanism is provided with an annular groove near the tail end, the tension sealing ring I, the spacing mechanism and the tension sealing ring II are sequentially sleeved in the annular groove near the tail end along the axial direction, the peripheral surface of the prepressing mechanism is provided with the annular groove.
After the tightness adjusting mechanism is rotated, the bolt can linearly move along the axial direction of the bolt shaft; when tensioning sealing is needed, after the tightness adjusting mechanism is rotated, the tightness adjusting mechanism extrudes the prepressing mechanism, the prepressing mechanism extrudes the first tensioning sealing ring, the second tensioning sealing ring and the fixing mechanism, and the tensioning sealing rings are extruded, deformed and expanded in the radial direction to complete the sealing process; otherwise, the sealing is loosened.
Compared with the prior art, the invention has the beneficial effects that:

Detailed Description
The invention is described in further detail below with reference to the figures and specific examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1-2, the tension sealing device includes a bolt shaft 1, a tightness adjusting mechanism 2, a prepressing mechanism 3, a spacing mechanism 4, a fixing mechanism 5, a foolproof mechanism 6 and a tension sealing ring 7, wherein the bolt shaft is sleeved with the fixing mechanism, the foolproof mechanism and the tightness adjusting mechanism in sequence from the top end to the tail end, the foolproof mechanism is sleeved with the prepressing mechanism, the bolt shaft is fixedly connected with the fixing mechanism sleeved on the top end of the bolt shaft through a bolt, the fixing mechanism is of a ring structure, an annular groove near the tail end is formed in the outer peripheral surface of the fixing mechanism, the first tension sealing ring, the spacing mechanism and the second tension sealing ring are sleeved in the annular groove near the tail end in sequence along the axial direction, the annular groove near the top end is formed in the outer peripheral surface.
The tensioning sealing ring is deformed by external force based on the elastic property of the tensioning sealing ring material (EPDM material) so as to realize tensioning. Firstly, in the using process, because the tightness adjusting mechanism is in a loose state, the tightening sealing ring is not extruded, and can be smoothly inserted into the structural hole of the membrane component in the state; when the tension adjusting mechanism is confirmed to be completely inserted into the structural hole of the membrane assembly and rotated, due to the foolproof mechanism, the bolt shaft cannot synchronously rotate while the tension adjusting mechanism is rotated, the tension adjusting mechanism extrudes the pre-pressing mechanism under the action of threads and simultaneously transmits pressing force to the spacing mechanism and the two tension sealing rings, the tension sealing rings radially deform outwards under the extrusion of external force, and the tension sealing rings radially deform outwards to extrude the structural hole of the membrane assembly to complete sealing. At the moment, the outer bolt shaft is connected with an air source, and the leakage detection work can be carried out by adjusting the pressure to a required value; the leak detection pressure is far less than the tension force of the tension sealing ring, so that the leak detection device can realize the sealing effect and can also ensure that the problem of membrane component separation cannot occur. After the leak detection work of the membrane assembly is finished, the tightness adjusting mechanism is unscrewed, the tension sealing ring is restored to the original shape without external force, the membrane assembly is pulled out of the structural hole of the membrane assembly, and the whole process is finished.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
