VALVE.
Specification of Letters Patent.
Patented Dec. 13, 1921.
Application filed September 17, 1920. Serial No. 410,875.
To all whom it may concern.
Be it known that I, HOSEA K. KRIEBEL, a citizen of the United States, and resident of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented an Improvement in Valves, of which the following is a specification.
The object of my invention is toprov'ide a construction of steam supply valve suitable for steam heating systems employing radiatorsand especially adapted for con-' trolling the supply of steam to the radiator while permitting the escape of water of condensation from the radiator into the supply main, as is suitable in what is known as a one-pipe system, whether operating as a pressure or vacuum' system.
More particularly, my object is to provide a control valve body having a movable plug valve fitted therein, preferably with adjustable parts to control the steam passage therethrough, the body further provided with a water seal return or by-pass passage from the outlet port to the inlet port at a lower level, said return passage controlled by an auxiliary valve piece movable with or actuated by the plug valve, whereby when the plug valve is in open position, the water seal is free to operate to permit of water of condensation to pass in the reverse direction to the flow of the steam through the valve and when the plug valve is fully closed, the water seal or by-pass passage is also positively closed by the auxiliary valve piece. In the preferred construction, the main or plug valve may be closed to an extent sufiicient to shut oil passage of steam and yet allow the auxiliary valve to remain open'to enable the water seal to permit escape of water of condensation from the outlet side, but at the same time in no wise preventing its complete sealing by the auxiliary valve when so. desired and without again opening the steam passage through the plug valve.
My invention also comprehends details of construction which, together with the features above stated, are fully described hereinafter and more particularly pointed out in the claims.
Referring to the drawings; Figurel is a vertical sectional view through a valve embodying my invention; Fig. 2 is a horizontal section of the same taken on line 22 of Fig. 1; Fig. 3 is a horizontal section of the same on line 3-3 of Fig. 1, Flg. e
is an elevation of the plug valve piece removed from the valve body; and Fig. 5 is'a transverse sectional view of the same on line 55 of Fig. 4c.
2 is the valve body, having the inlet port 3 and outlet port 4, the construction in the particular illustration showing these parts as 1n an angle valve suitable for use as a steam supply or control valve for steam heated radiators. Interposed between the nlet and outlet portions of the valve body 1s a vertical plug valve seat 9 in which is fitted a tapered plug valve 6 having transverse steam ports 6 and a cylindrical central chamber 6 with which the ports 6 communicate. The diameter of the chamber 6 is sllghtly greater than the width of the ports 6 and the upper part of one of the ports is laterally notched as at 6 (Figs. 4 and 5) through which disks 22 may be inserted into the chamber 6 and allowed to rest one on top of the other to more or less reduce the steam passage through the plug valve piece to the extent desired to give to the valve the capacity necessary when the valve is fully opened to suit requirements of large or small radiators.
The plug valve piece 6 is provided with an upward stem 7 terminating in a square shaped top 16 to which is fitted a handle 8 and a pointer 15. The steam 7 extends through a stufling box in the bonnet 10 screwed upon the body 2, the stufiing box having packing 13 and a screw gland ll to compress it about the stem. Between the bonnet 10 and the top of the tapered plug valve piece 6 is arranged a coil spring 12 for normally holding the plug valve to its seat 9. Packing 11 may be interposed between the bonnet 10 and the upper rim of the body, as shown-in Fig. 1.
17 isa water sealpassage or trap constituting a by-pass having an upper port 18 opening into the outlet port 4 of the valve body and also having a lower port 19 opening into the inlet port 3 or lower part of the valve body. The upper port 18 opens from the bottom of the outlet port 14 and the lower port 19 opens horizontally into the chamber of the body immediately below the plug valve 6 and terminates in a valve seat which is controlled by an auxiliary valve piece 20 carried on the lower part of an arm or extension 21 from the bottom of the plug valve 6, the said extension acting as a crank arm for operating the valve piece 20. The operation of this auxiliary valve will now be understood, as it is apparent that when the plug valve is fully opened the valve piece 20 will be far away from the port 19; and that even when. the plug valve is turned to shut off passage of steam (Fig. 2), the auxiliary valve 20 will still leave the trap ofseal open. If, however, it is desired to close the trap, then the plug valve is turned until valve piece 20 seats upon the valve seat at port 19 and at which time the ports 6 of the plug valve will be fully closed.
' iliary valve 20 upon its seat acts as a stop for the main valve. In this condition, the steam radiator will be mechanically closed from the steam piping. At all other positions of adjustment, the trap or water seal will permit water of condensation to drain backward from the radiator into the supply main, while keeping the passage 17 sealed with water to prevent passage of steam; and it will be understood that this capacity for drainage of water of condensation may be carried on whether steam is admitted through the plug valve piece 6 or not. The especial purpose of the seal 17 is to enable baclcfiow of water of condensation, without requiring it to pass through the steam ports 7 6 or in any way interfering with the regulated supply of steam to the radiator; and
. secondary, to prevent water hammering or other noises in the valve due to the reverse direction of flow of water and steam and their interference when required to simultaneously pass through the same passages.
I have shown the construction of my im proved valve in the general form preferred to meet the requirements of steam heating systems and particularly those in which the water of condensation fromthe radiator is required to flow back through the steam supply pipe, such as in a one-pipe system, whether of the pressure or vacuum type, but I do not restrict myselfto the application of the valve to these uses, nor to the specificv form of the details of structure shown.
It will now be apparent that I have devised a novel and useful construction which embodies the features of advantage enumerated as desirable, and while I have in the present instance shown and described the preferred embodiment thereof which has been found in practice to give satisfactory and reliable results, it is to be understood that I do not restrict myself to the details, as the same are susceptible of modification. in various. particulars without departing from the spirit or scope of the invention.

2. The invention according ':to claim 1, wherein the'main valve is inthe form of a plug valve having a port through it having perm tting variation adjustable means for wherein the adjustable means for permitting variation of theoapacity of the pertin the plug valve comprises a plurality of rerhov-V able disks normally resting one upon the other and movable with the plug valve.-
4. The invention according to claim 1,

6. The invention of claim 5, when further distinguished by having the valves and their seats so relatively positioned that the main valve may be fully adjusted for controlling flow of steam without closing the auxiliary valve but so that when the auxiliary valve is fully closed the main valve is fully closed also 7 In a steam valve, the plug 'valve'having a central. chamber, ports on oppositesides opening through its walls into the central chamber and of a width lessthan the width of the said chamber, one of the ports having notches on each sideat its top to provide space of the full widtho-f the central chamber, combined with a plurality of fiat disks adapted tobe inserted into the central chamber through the notched portion of the HOSEA K. KRI'EBEL.
