JAMES A. DONNELLY, OF BROOKLYN, NEW YORK.
VALVE.
Specification of Letters Eatent.
Patented Apr. 28, title.
Original application filed May 12, 1906, Serial No. 316,426. Divided and this application filed April 16,
To (all whom it may concern:
Be it known that T, JAMES A. DONNELLY, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Valve, of which the following is a specification.
This application is a division of my application filed May 12, 1906, Serial No. 3164-26.
The valve which is the subject of this invent-ion is more particularly intended as a check valve in the outlet of radiators of steam heating systems, although it may be applicable to other purposes.
The accompanying drawing shows a ver-' tical section of the valve.
1 is the valve casing of the ordinary form containing the inlet passage 2, and the outlet passage 3.
4 is the cap or bonnet screwthrcaded to the casing.
A counterbore 5 is made at the bottom of the valve chamber 6 in which is seated a tubular section 7 insertible through the opening 8 at the top of the valve casing. This tubular section contains the opening 9, the sides of which constitute the seat of the valve. The top of the tubular section 7 is closed by the plug 10 which fits firmly therein.
1.1 is a spring bearing on top of the plug 10 and serving to hold the tubular section 7 firmly on its seat in the counterbore 5.
12 is a tubular section to hold the spring 10 in position.
13 is a lug on the bottom of the plug 10 from which pivotally hangs the valve 14: preferably of the form shown. It contains a conical projection 15 extending through the passage 9. It contains also at the base of the conical projection, an impact surface 16 preferably in the form of an annular groove in which the water rushing through the passage 9 around the conical projection 15 will strike.
17 are weights in the form of washers secured to the rear of the valve by the screw 18. The weight of the valve tending to hold it against its seat may be regulated by varying the number of these weights. The weight of the valve will be selected and determined so as to be suiiicient to maintain the pressure in the outlet passage 3 at a point below that in the inlet passage 2.
Serial No. 490,248.
For instance, if the pressure in the passage 2 be two pounds, the valve will be weighted in such proportion to the area of the valve seat as to maintain pressure in the passage 3 at 1% pounds. It is desirable that the area of the restricted opening in the passage 9 around the conical projection 15 be less than the area of the pipes leading to and from the valve so that the flow in the outlet pipe will not be affected sufficiently to materially change the pressure.
hen the bonnet or cap 4; is removed, the whole structure inside of the valve casing can be readily removed and replaced through the opening 8 of tne valve casing. The removal does not disturb the adjustment of the valve and its seat and when replaced no adjustment is required to return the parts to operative position. As an example of the relative size of the opening 9 I may say that it the pipe 19 be the outlet pipe from a steam radiator and be inch internal diameter, a proper size for the opening 9 will be it inch in diameter. This opening 9 being located near the bottom of the passage 2 for proper drainage of the water will in consequence of this location and in consequence also of its limited size, be particularly liable to clogging, and hence there is great utility in having a member 7 which is removable from the valve chamber and which carries bodily both the valve and the valve seat. The structure consisting of this member and the valve and valve seat remains substantially self-sustaining and intact while being removed for cleaning and replacin Having thus described my invention what I claim is:
,1. In a valve of the class described, a valve casing having inlet and outlet passages, a seat surrounding the outlet passage, a tubular casing within the valve casing and having an open end seated on said seat, the opposite end of said tubular casing being closed, said tubular casing having a lateral port through its side wall and communicating with said inlet passage, and a valve suspended within said tubular casing for free swinging movement toward the inlet to close said port and away from the inlet to open said port.
2. In a valve of the class described, a valve casing having inlet and outlet passages, a seat surrounding the outlet passage,
a tubular casing within the valve casing and having an open end seated on said seat, the opposite end of said tubular casing being closed, said tubular casing having a lateral port through its side wall and communicating with said inlet passage, a valve suspended within said tubular casing for free swinging movement toward the inlet to close said port and away from the inlet to open said port, and means for regulating the swinging movement of the valve to maintain a determined relation of the pressures in the inlet and out-let passages of the first named valve casing.
3. In a valve of the class described, an outer casing having inlet and outlet passages, a separate inner casing bodily removable from the outer casing and having a lateral port through its side wall and communicating with said inlet passage, and a valve suspended inside said inner casing and provided with a conical project-ion extending through said lateral port, said projection being movable toward said port to close it and away from said port to open the same.
4. In a valve of the class described, a valve casing having inlet and outlet passages and an opening, a tubular casing within the valve casing insertible and removable through said opening, said tubular casing being in longitudinal alinement with the outlet and having a lateral port adjacent and communicating with the inlet, a pivoted valve suspended from the casing and having a conical head engaging said lateral port, said valve being movable toward the inlet to close the lateral port and away from the inlet to open said port.
In testimony whereof, I have hereunto signed my name in the presence of two subscribing witnesses.
