C. S. HAND AUTOMATIC TIMING VALVE Filed Dec. 6, 1929 June 7, 1932.
Patented June 7, 1932 UNITED STATES- PATENT, OFFICE CLARENCE S. HAND, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO UNITED EN- GINEERS & CONSTRUCTORS IN 0., OF PHILADELPHIA, PENNSYLVANIA, A CORPOBA- 'I'ION OF DELAWARE AUTOMATIC TIMING VALVE Application filed December 6, 1929. Serial No. 412,108.
The present invention relates to valve control. The object of the invention is to provide new and improved apparatus whereby a valve in a fluid passage way can be quickly opened and by means of which the valve will be automatically closed at the end of a predetermined period of time. The apparatus also includes means by which the length of the above mentioned period of time may be varied at will.
Among the uses of such apparatus may be mentioned the control of valves in water lines to sprays for the cooling of hot coke from ovens or retorts. In such coke cooling it is not desirable to spray more water onto the coke than is necessary to prevent its combustion. The coke arrives under the sprays at a fairly uniform temperature, and for a certain quantity of coke the desirable minimum of cooling water can be determined. l Vith a supply of cooling water at a uniform pressure, the valve in the water line to the sprays should be open a definite and determinable period of time to supply the desired quantity of cooling water per unit of hot coke.
According to present practice the valve is opened by an operator, and closed by him at the end of the spraying operation. This requires his constant attendance and his close attention to assure that the period of valve opening is neither too long or too short. If he is called away or his attention distracted, too much water is likely to be used.
The apparatus of the present invention antomatically closes the valve at the predetermined time, obviating the necessity of the operators attention and relieving him for other duties.
The invention will be more particularly -described in connection with the attached as 2, through the header 3. 4 is a valve in the fluid way, preferably of the balanced globe type. 5 is the valve stem to which is attached,
(in the illustration by the set screw 6) the member 7, which forms a continuation of the .valve stem. The member 7 slides on the guides 8, which form the support of the hydraulic operating cylinder 9. The piston 10 of the cylinder is attached to the piston rod 11, which extends through an opening. in the end of the member 7 away from the valve stem 5, and preferably slides therein. The rod 11 terminates at its end away from the piston in the head 12, preferably attached to it, by the set screw 13. Between the member 7 and the bonnet ofthe valve 4, are provided the springs 14.
The hydraulic cylinder 9 is provided with the operatlng fluid lines 15 and 16 which alternately serve as inlet and outlet means, and which are connected through the four way valve 17 so that they may be connected to the inlet pipe 18, leading from a supply of fluid under pressure, or the outlet pipe 19 by turning the four way valve by the lever 20. 21 1s a strainer in the inlet pipe.
The fluid line 15 is provided with a check valve 22, arranged to permit flow therethrough toward the hydraulic cylinder but not in the opposite direction. There is also provided the by-pass connection 23, around the check valve 22 and which is provided with the adjustable needle valve 24.
In operation, assuming the valve 4 is closed, the operator turns the lever 20, so as to connect inlet pipe 18 with line 15, and outlet pipe 19 with line 16, fluid under pressure flows through the line 15, the check valve 22 opening to permit full flow. The piston is quickly forced upward, the cylinder exhausting through the unimpeded line 16, the valve 17 and pipe 19. The valve 4 has been previously held shut by the pressure of the head 12 of the piston rod 11 on the end of the valve stem 5, with the springs 14 compressed.
The piston rises quickly, as described above, andthe springs push upward on the bottom of the member 7, but preferably are not strong enough to lift the valve. Toward the end of the travel of the piston the head 12 engages the member 7 and lifts it, opening the valve 4 to the desired extent. A stop 25 may be provided to terminate the valve opening.
The operation has now reached the point illustrated in the drawing.
Instead of staying in attendance until it is time for valve 4 to be closed, the operator throws the lever 20, so as to connect line 15 with outlet pipe 19 and line 16 with inlet pipe 18. The valve 4: will be automatically closed at the end of a predetermined time and requires no further attention by the operator.
The fluid pressure through line 16 is admitted above the piston; but the check valve 22 in line 15 closes and-the exhaust from the cylinder must pass through the by-pass connection 23 and the needle valve 24. The needle valve has been adjusted to permit the exhaust at a predetermined rate, and the piston with its rod moves down slowly. The head 12 passes down between the sides of the member 7, the valve 4 remains open, held thus'by the springs 14, until the head 12 engages the upper surface of the base of the member 7 (or the end of the stem if it extends through the base of the member 7.) After the above engagement further travel of the piston compresses the springs and closes the valve. The valve is held shut by the fluid-pressure above the piston. I With a supply of fluid at substantially uniform pressure for operating the hydraulic cylinder, it will be obvious from the above that the piston will move downward at a substantially uniform rate, depending on the setting of the needle valve in the check valve by-pass, until it begins to actuate the valve 4. Its rate of travel will then be slightly decreased due to the resistance of the springs.
The command for the closing action may be initiated as soon as the valve has been mounted on said valve, a stem in said valve, a member mounted on said stem and guided by said guide rods, pair of. springs on said guide ro s between said valve and said member, a piston, an adjustable stop for said member mounted on said guide rods, a connection between said piston and said member, a cylinder cooperating with said piston, a means for supplying pressure, a means for permitting exhaust of pressure, a control valve connected to said pressure supply means and said exhaust means, an unobstructed connection between said control valve and said cylinder on one side of said piston, and a connection between said control valve and said cylinder on the other side of said piston including a check valve and a bypass around said check valve including a valve.
