Abstract

28,215. Goold, W. T. Dec. 28. Lift valves; actuating valves; casings; spindles. - A steam-trap of the Geipel type has a cup-shaped main valve J opening downwards against the pressure of the fluid, and provided with a relief port closed by a relief valve K, also opening against the pressure of the fluid, and against the action of a spring K<3>; in a modification, the relief valve is dispensed with, an equilibrium valve being used. An inlet pipe A admits fluid through ports G<1> to a space below the main valve, and when the tube A contracts, a spindle K<1>. carrying the relief valve is forced against an adjustable screw M' on a pivoted lever M<3>. The pressure of the fluid on the upper side of the valve together with the weight of the valve causes the valve to open, the liquid being discharged through the tube B. The valve casing is formed by three parts D<1>, D<2>, D<3> screwed together. The valve spindle passes through a stuffing-box L which is out of contact with the steam. In the form shown in Fig. 2, the equilibrium valve has two faces J', J<2>, the tube A opening to the space between the faces. The valve spindle is provided at the top with a steel ball S to reduce friction, and the part D<3> may be omitted, the spring being placed above the stuffing-box. According to the Provisional Specification, the valve spindle may be formed in two parts with a loose joint between the parts, and a light spring may he used to open the main valve. Specifications No. 7860, A.D. 1893, No. 21,571, A.D. 1894, and No. 12,131, A.D. 1896, [Abridgment Class Heating], are referred to.
