LEON BLQCH, OF NEW YORK, N. Y.
Patented Apr. 15 1919.
Application filed ma 24, 1918. Serial No. 236,367.
To all whom itmay mm.-
Improvements in Valves, of which the following is a specification.
This invention relates to valves and particularly to*globe valves for high pressure its initial contact with the valve seat and use and it has for its primary object the provision of a valve chamber having a seat the opening through which is disposed substantially in line with the longitudinal center of the valve chamber whereby the steam will be free for aconti'nuous and straight passage through the chamber to be thereby held against being trapped inv the chamber when the valve is opened; combining with the seat 7 of the just stated character, a vertically movable stem and a valve suspended for universal movement from the stem andv adapted to be wholly arranged above the opening in the seat when the valve is opened.
Another object of the invention is to provide a valve including a chamber having a seat in which the opening therein is disposed substantially in a straight line with the longitudinal center of the chamber, and a valve which is adapted to assume a horizontal position when opened and which is arranged and disposed to be canted through firmly positioned thereagainst to effect a perfeet joint between the seat and valve when the latter is seated.
With the above and other objects in viewwhich will appear as the nature of the in.
vention 'is better understood the same consists in the improved construction and novel arrangements of parts which will hereinafter be fully described and particularly pointed out in .the claim.
In the accompanying drawings, has been illustrated, a single and preferred form of 'The valve consists of a chamber 5 having a diaphragm or wall 6 which is arranged at an angle other than a right angle, to the longitudinal axis of the chamber and provided with a seat 7 whose opening 8 lies substantially in line, with the longitudinal center of the 'valve chambefto permit of a direct straight passage of steam through the 1 chamber when the valve is opened. Rising .from the chamber in vertical alinement with the opening through the diaphragm or Wall 6 is a threaded collar 9 which receives a cor respondingly threaded'bonnet or support 10 for 'a vertically adjustable valve stem 11, the same havinga thread 12 which isreceived in threaded bore 13 in the support in order that the valve can be moved up and down and satisfactorily held in theflesired position. The support 10, when removed from'the collar 9 uncovers theinterior of J the collar in order that a suitable grinding tool may be advanced against and operated over the seat 7 as will, be appreciated on section is threadedly connected at 17 with to which the valve maybe placed. The base section 18 is provided with a threaded stem 22 which passes through the disk 20 and bevneath the disk said stem is connected with 'position of the latter. When the valve is opened as shown in Fig. 1 the disk 20 gravitationally' assumes a horizontal position. A
' movement of the valve stem in the direction canted and thereby made to fully contact with the seat as shown in Fig. 2. It will be observed that through this arrangement when the valve disk is opened as shown in Fig. 1, it is disposed above the highest point of the valve opening 50- as to provide, in combination with the position of the valve opening, a perfect free passage for the discharge of steam through the valve chamber.
In order to permit the valve disk to assume such position, the member 10 is chambered at 24 to accommodate the disk.
What is claimed as new is A valve structure comprising a chamber member having a valve seat, a stem movable relatively to the seat, and a flexibly connected valve disk supported from said stem,
the seat being arranged to intercept the path' of movement of .thedisk and adapted to effect a cant-ing action of the disk against the is moved toward the
