Abstract
A pressure gauge attachment system includes a thread having a thread stop as well as at least one engagement element that is configured to defect during installation and effectively provide an interlock after installation. The system is suited for rapid and simplified installation, inherently provides automatic orientation of a pressure indicator, enhanced sustainability, flexibility in manufacturing, as well as provides a secure, reliable fluid-tight sealed connection that does not rely upon a pipe thread, additional couplings or clamping nuts for retention.
Claims20
A pressure gauge attachment system comprising:
- a first member comprising a socket, wherein the socket comprises a thread and at least one engagement element;
- a second member comprising a connection port, wherein the connection port comprises a thread and at least one engagement element, wherein during installation of the connection port into the socket, the thread of the connection port engages the thread of the socket and the at least one engagement element of the connection port deflects and provides an interlock with the at least one corresponding engagement element of the socket.
A polymeric housing for a gauge module comprising:
- an enclosure for the gauge module, a port for fluid communication with the gauge module, said port having one revolution of functional connecting thread about its outer circumference for engaging a mating receiving socket;
- an elastically bendable radial flange disposed upon the communication port, said flange having a lock engagement feature and configured to deflect upon contact with the first opposing face of a thread bearing receiving socket before the connecting thread is fully engaged whereby the receiving socket has a mating locking element to engage the radial flange lock engagement feature to prevent rotation of the polymeric housing.
