摘要

2523. Braithwaite, C. C. Jan. 31. Pressure-regulating valves.-A pressure-regulating valve for controlling the water-supply in irrigation works, town services, &c. consists of a tubular member c of vena contracta shape, the ends c1, c2 of which work closely in a chamber. The valve is supported by a pivoted lever l carrying a balance weight e, a second weight f being provided on a vertical arm of the lever in order to prevent a pulsating movement of the valve. Increase in the pressure of the fluid entering at a moves the valve towards a fixed seat d and so throttles the passage d1. By means of a spindle and hand-wheel h, the valve may be used as a stop-valve. In a modification, the valve is placed horizontally, being supported by a weighted lever as before.
