Description

Technical Field

[0001] This utility model relates to the field of flow measurement technology, and in particular to a double-sealed self-locking structure for an electromagnetic water meter converter and its auxiliary installation fixture. Background Technology

[0002] Electromagnetic water meters are typically installed in damp underground environments, where pipe leaks and severe weather conditions such as rain and snow can cause them to become submerged. Therefore, it is crucial to ensure that the casing of the electromagnetic water meter is sealed to prevent water leakage.

[0003] Currently, the traditional installation method involves assembling the screws along the axial compression direction of the sealing ring to constrain the sealing structure and ensure preload. However, this method is prone to reduction or even loss of preload due to vibration during transportation, installation, and use, resulting in a decrease in the compression ratio of the sealing ring. Furthermore, non-sales personnel can easily disassemble the electromagnetic water meter, potentially leading to seal failure. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, one objective of this utility model is to provide a double-sealed self-locking structure for an electromagnetic water meter converter, which solves the problem that existing electromagnetic water meter installation methods are prone to a decrease or even loss of sealing pre-tightening force due to vibration during transportation, installation, and use, resulting in a reduced compression ratio of the sealing ring; furthermore, non-after-sales personnel can easily disassemble the electromagnetic water meter, which may ultimately lead to seal failure. The second objective is to provide an auxiliary installation fixture.

[0005] To achieve the above and other related objectives, this utility model provides a double-sealed self-locking structure for an electromagnetic water meter converter, comprising:

[0006] A housing for assembling remote transmission components and measuring components, wherein one end of the housing has a first opening;

[0007] A cover is provided to cooperate with the housing to close the first opening. The cover has a second opening with a diameter larger than that of the first opening.

[0008] A first sealing component is disposed between the sidewalls of the housing and the cover, and the first sealing component is used to provide a radial seal for the converter;

[0009] A second sealing component is disposed between the end of the housing located at the first opening and the bottom of the housing cover, and the second sealing component is used to provide an axial seal for the converter;

[0010] The shell is provided with a threaded locking hole, the shell cover is provided with a through hole, along the axial direction of the converter, the through hole is arranged in a staggered manner with the threaded locking hole, and the position height of the through hole is greater than the position height of the threaded locking hole. The shell cover and the shell are locked by the locking part passing through the through hole and the threaded locking hole.

[0011] Optionally, the shell comprises a shell body and a connecting piece, the connecting piece is welded and fixed with the shell body, and the threaded locking hole is arranged on the connecting piece.

[0012] Optionally, a first sealing groove is arranged on the side wall of the connecting piece, and the first sealing groove is used for mounting the first sealing part.

[0013] Optionally, a first protruding part is arranged on the side wall of the shell cover, and the first protruding part is used for extrusion fitting with the first sealing part.

[0014] Optionally, a second sealing groove is arranged on the bottom of the shell cover, and the second sealing groove is used for mounting the second sealing part.

[0015] Optionally, a second protruding part is arranged on the end of the connecting piece, and the second protruding part is used for extrusion fitting with the second sealing part.

[0016] Optionally, the shell is provided with an antenna interface and a pulse output interface.

[0017] An auxiliary installation tool applied to the double-sealing self-locking structure of the electromagnetic water meter converter, the auxiliary installation tool comprises a bracket, the bracket comprises a bearing part and an installation part, the bearing part is used for bearing the shell, and the installation part is used for installing a pressing assembly, the pressing assembly is used for pressing the shell cover, so that the position height of the through hole and the threaded locking hole along the axial direction of the converter is consistent.

[0018] Optionally, a threaded hole is arranged on the installation part, the pressing assembly comprises a screw rod and a handle, the screw rod is threadedly connected with the threaded hole, the handle is connected to one end of the screw rod along the axial direction, and the axis of the handle is perpendicular to the axis of the screw rod.

[0019] Optionally, a pressing part is arranged on one end of the screw rod close to the shell cover along the axial direction, and the pressing part is used for abutting fitting with the shell cover.

[0020] As described above, this utility model has the following beneficial effects: This application uses a double-sealing structure to provide radial sealing for the converter by setting a first sealing component between the housing and the cover, and an axial sealing component for the converter, effectively ensuring the sealing performance of the converter. The through-hole on the cover and the threaded locking hole on the housing are offset along the axial direction of the converter. When the cover and housing are locked together by the locking component passing through the through-hole and engaging with the threaded locking hole, the cover will press the second sealing component downwards along the axial direction of the converter. The rebound energy of the second sealing component will exert an upward thrust on the cover along the axial direction of the converter. The downward locking force of the locking component on the cover and the upward thrust of the second sealing component on the cover create a self-locking structure between the cover and the housing. Through the design of this self-locking structure, the electromagnetic water meter is less prone to a decrease or even loss of sealing preload due to vibration during transportation, installation, and use, thereby avoiding a reduction in the compression ratio of the sealing ring and effectively ensuring the sealing performance of the product. In addition, during use, non-professionals should not disassemble the electromagnetic water meter, thus avoiding the problem of non-professionals damaging the internal components and sealing effect when disassembling the electromagnetic water meter.
