Gas Shut-Off Valve

US Patent:
4469124, Sep 4, 1984
Filed:
Jan 18, 1982
Appl. No.:
6/340376
Inventors:
Robert J. Bronsky - New Baltimore MI
Dennis B. Clark - Flat Rock MI
Jeffrey A. McKeen - Detroit MI
Assignee:
Michigan Consolidated Gas Company - Detroit MI
International Classification:
F16K 1704
US Classification:
137464
Abstract:
A shut-off valve includes a valve stem or actuating member operatively connected to a pressure-responsive apparatus. The pressure-responsive apparatus is acted upon by fluid in a pressure chamber such that the valve mechanism is held open to permit fluid flow therethrough. A spring or biasing means is provided that automatically closes the valve mechanism whenever the pressure chamber is evacuated or depressurized such that the pressure-responsive apparatus can no longer maintain the shut-off valve in an open position.

Shut-Off Actuating Device

US Patent:
4437347, Mar 20, 1984
Filed:
Jan 18, 1982
Appl. No.:
6/340377
Inventors:
Robert J. Bronsky - New Baltimore MI
Dennis B. Clark - Flat Rock MI
Jeffrey A. McKeen - Detroit MI
William A. Przybylski - Dearborn MI
Assignee:
Michigan Consolidated Gas Company - Detroit MI
International Classification:
G01F 1500
US Classification:
73272R
Abstract:
A shut-off actuating device includes a stop member biased toward a position where it interferes with the movement of a linkage apparatus of a fluid flow measuring device. The fluid flow measuring device is adapted such that once the linkage apparatus is disabled or rendered inoperative, fluid flow through said device is thereby prevented. A solenoid-operated apparatus is provided which includes a solenoid rod or arm that normally engages the stop member to hold it in a retracted position out of said interference with the linkage apparatus. Once the solenoid apparatus is energized, the solenoid rod is disengaged from the stop member and the stop member is thus allowed to extend into an interfering relationship with the linkage apparatus, thereby disabling said apparatus or rendering it inoperative in order to shut off the flow of fluid through the fluid flow measuring device.
