| 摘要 | A pressure transmitting device is disclosed having a member which defines a passage for the transmission of fluid pressure and a diaphragm associated with the passage defining member. There is also provided an annular securing member for securing said passage-defining member directly or indirectly to an apparatus containing fluid whose pressure is to be measured in such manner that the pressure of said fluid is applied to said diaphragm. The diaphragm is sealingly secured directly to the passage-defining member, and the securing member is detachably engageable over the said passage-defining member to secure the latter to fluid-containing apparatus. | ||||||
| 权利要求 | 1. A pressure transmitting device of the type adapted to be used with a cooling member, said pressure transmitting device comprising: a. a first annular member having means for receiving a pressure measuring device, said first annular member including an axially extending, cylindrical connection fitting, including an exterior mounting surface for mounting a cooLing member around a portion of said connection fitting, said fitting having a first passage way therethrough said mounting surface surrounding at least a portion of said passage way, b. a second annular member having a second passage way therethrough that is adapted to be placed in communication with a fluid pressure to be measured; c. diaphragm means sealingly secured between said first and second annular members for preventing fluid communication between said first and said second passage ways; and d. means for releasibly clamping said first and said second annular members to each other. 2. The device according to claim 1 wherein a cooling member is further included. 3. The pressure transmitting device according to claim 2 wherein said cooling member is in the form of an annular, slip-on casing having connections therein for the passage of a cooling medium. 4. The device according to claim 2 wherein said cooling member is in the form of a slip-on ring having axially extending cooling vanes. 5. The device according to claim 2 wherein said cooling member is in the form of a slip-on ring having radially extending cooling vanes. 6. The device according to claim 2 wherein said cooling member comprises two half sections each having flange portions and means for clamping said flange portions together. 7. The device according to claim 6 wherein said two half sections are hollow and wherein there is further included a detachable cover for permitting access to the interior of said hollow half sections. 8. The device according to claim 6 wherein said two half sections are each provided with cooling vanes. 9. The device according to claim 8 wherein said vanes are provided with a stepped region. 10. The device according to claim 1 wherein there is further provided an annular disc of thermally insulating material positioned between said first annular member and said diaphragm. |
