VALVE-SEAT STRUCTURE FOR BIBBS AND THE LIKE.
Application filed August 17, 1927.
This invention relates to a valve especially adapted for house water service systems. In such systems, it becomes necessary or advisable to replace valve parts such as valve seats, washers and the like. Compression valves are commonly used and the removal and replacement of the valve stems and washers is easily accomplished. In some instances, replaceable valve seats have been provided. These are commonly of ring form and serve for engagement with corresponding threads in the partition wall of the valve body. Ordinarily, while a valve is being worked upon, the valve stem and washer being removed, it is necessary to shut off the water so that the work may be performed.
The present invention has for its primary object the provision of a valve having a replaceable valve seat arranged so that it may be conveniently removed by the aid of the valve stem. Another object of this invention is to provide a valve seat having automatic means to shut off the ports in the valve upon removal of the valve stem and washer. In addition to the broader objects of this invention, there are certain details of design, whereby a simple, economical and efficient structure is obtained, one which does not depart from the usual valve structure. These objects together with other objects and corresponding accomplishments are obtained by means of the embodiment of my invention illustrated in the accompanying drawing, in which:
Fig. 1 is a section through a complete valve structure showing a portion of the stern in elevation, the valve being in closed position; Fig. 2 is a section as seen on the line 22 of Fig. 1;Fig. 3 is a fragmentary sectional view part with the valve stem in elevation showing the position of the valve parts with the valve open; Fig. 4 is a sectional view showing the bonnet removed and the valve stem inserted in the seat for removal of the latter; and Fig. 5 is a section as seen on the line 55 of Fig. 4.
Referring with more particularity to the drawing, the valve body 5 is provided with an inlet 6 and an outlet 7 separated by a partition wall 8. The partition wall provided with a port for the passage of water from the inlet to the outlet. In alignment with the portis a tubular extension 9 having an internal thread 10 for the valve stem and an 53 external thread 11 for the bonnet. Extending into the valve through the tubular pen Serial No. 213,609.
tion is a stem 12 which is suitably packed by means of :onnet structure 13. The construction ust described is Well known.
Referring to the partition 8, the inner wall of the port thereof is internally threaded so as to receive a ring seat member 14. The seat member is suitably threaded and provided with a limiting shoulder so that it may be threaded'into position within the port. At the center of the seat member there is an opening having a female broach 1552s shown in Fig. 2. This broach corresponds to the male breach 16 upon the other end of the valve stem. Broach 16 is designed to receive a handle 17. The valve stem with its breach and handle are of the usual construction. However, the valve seat is novel in that the female broacl1 correspending to the broach on the stem is provided. The valve seat is provided with a cage 18 having suitable lateral openings and housing a reciprocable valve member 19.
The valve member 19 is in the form ofa plunger arranged so that it cannot be rocked in the cage. It co-operates with a valve seat in the valve seatmember so that when in its upper position the port through the valve seat will be closed. Ribs 25 act as guides for the valve and provide clearance between it and the cage for the flow of water around it. The arrangement is such that if there is a pressure on the inlet side and the valve 19 1S unrestrained, pressure acting through opening 20 in the cage causes the valve to be moved upwardly and seated so as to close the port through the valve seat.
The valve stem has an enlargement adjacent its lower end provided with a thread 21 for meshing with the thread 10 in the tubular portion of the valve body. A valve head 22 is also provided and has a bore tapped to receive a screw 23. The valve head is arranged to be engaged with the head of screw 23; The screw also serves to hold a washer 24. in position. The washer is of the usual construction.
The valve in its assembled position is shown in Figs. 1 and 3; The valve seat is positioned in the partition in the valve body and the valve stem is engaged by means of the threads 21 with the tubular extension of the valve body. The valve bonnet holds the packing about the stem and the handie is in position at the upper end. In the position shown in Fig. 1, the valve is closed, the washer being held upon its seat. To open the valve, the handle is turned so as to raise the washer from its seat. The valve stem is raised only enough to uncover the upper portion of the valve seat, the head of the screw 23 engaging a post on the valve 19 and preventing the valve 19 from moving upwardly against its seat. The open positionsof parts are shown in Fig. 3. it desired to remove the valve stem, the bonnet 13 is unloosened and valve stem unscrewed from the tubular extension. The valve 19 will then be forced to its seat by reason of the pressure of the water and there will be no leakage through the valve body. The cage and ribs hold the valve 19 from rocking thus preventing chattering during the n rm ep ration f t valve. Suppose tha it is desired to remove the seat. The valve handle 17 detached from the stem. The is then inverted as shown in Fig. it and inserted within the tubular extension so that the breach enters the broached opening 15 in the valve seat structure. By turning the stem, the seat may be detached and removed. Thus, there no separate tool required.
