Description
Jan. 16, 1934. BARR; 1,943,805
VALVE Filed March 8, 1932 BY%W Attorneys Patented Jan. 16, 1934 UNITED STATES PATENT OFFICE 3 Claims.
The present invention relates to improvements in valve construction and has particular reference to a valve of the self-closing type.
An important object of" the invention is the provision of a valve designed so as to become automatically closed when the pressure of the fluid admitted thereto reaches a predetermined point.
A further object of the invention is the provision of a self-closing valve particularly adaptable for vertical conduits.
Another object of the invention is the provision of a self-closing valve designed so that a ball mounted therein will be automaticaly forced to a closing position when the presure of the fluid passing through the valve attains a predetermined degree.
Still another object of the invention is the provision of a self-closing valve of the above character which will be relatively simple in construction and reliable in operation.
Other objects and advantages of the invention will become apparent as the description progresses.
zontal.
In the accompanying drawing forming a part of this specification and in which like reference characters are employed to designate corresponding parts throughout the same:
Figure l is a side elevational view of the assembled valve connected with vertical conduits,
Figure 2 is an end view of the same,
Figure 3 is a top plan view of the same,
Figure 4 is a central vertical section through the valve in open position, and
Figure 5 is a similar view of the valve in closed position.
Referring to the drawing, wherein for the purpose of illustration is shown a preferred embodiment of the invention, the numeral 10 generally designates the valve body or casing, which is of angular form and embodying a main section 11 and an angular laterally projecting section 12.
At the top of the main section 11 is provided an inlet port 14, shown having connection with a vertical intake conduit 15. At the bottom of the laterally projecting section 12 is formed a discharge port 16 having connection with a depending discharge conduit 17.
The main body section 11 defines an upper inlet chamber 19 communicating with an elongated bottom chamber 20. The bottom chamber 20 is formed so as to assume an inclined position, preferably at an acute angle to the hori- At the forward end of the chamber 20 is formed a reduced passage 21 affording communication between the chamber 20 and a substantially vertical outlet bore 22.
In the upper chamber 19 of the body is preferably formed an angular web 23 arranged so as to define a curved by-pass channel 24. at the rear portion of the main chamber.
In the lower rear portion of the main body section is fitted a screw plug 25.
Movably positioned in the elongated chamber 20 is a spherical or ball valve 26 normally assuming a retracted position against the plug 25 in the lower portion of the chamber 20 by force of gravity. When urged to an elevated forwardly disposed position, the ball 26 is adapted to be snugly seated against an annular flange 27 defining the passage 21 so as to tightly close this passage.
In use, when fluid, as for instance steam or water, is being discharged into the chamber of the valve body, at a relatively low pressure, that is, at a pressure below a predetermined set point, the fluid will not dislodge the ball valve 26 but will flow through the passage 21 and be discharged through the horizontally offset conduit 17. When, however, the pressure of the fluid increases and attains a predetermined pressure, the ball 26 will be automatically adjusted to move against the seat forming flange 27 so as to obstruct the passage 21 and close the valve. As will be noted from Figure 5, the fluid discharged into the valve will, by its passage through the main chamber, create a suction through the passage 21 tending to force the ball valve to a closing position. In addition thereto, the pressure of the fluid flowing through the by-pass channel 24 will exert a pressure against the rear of the ball to urge the same to a seated position.
This type of valve structure is particularly taken as a preferred example of the same, and
that various changes as to the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
Having thus described my invention, I claim:- U
1. In a valve of the character described, an angular body having transversely offset inlet and outlet ports, the interior of the body defining an upper inlet chamber and a lower inclined valve chamber communicating with a restricted passage, a web in the upper inlet chamber defining a by-pass channel, and a movable valve in the inclined chamber adapted to automaticaly assume a closing position to obstruct the passage in the body when the pressure of fluid admitted therein attains a predetermined point.
2. In a valve of the character described, an angular body having transversely offset inlet and outlet ports, the interior of the body defining an upper divided inlet chamber and a lower inclined valve chamber, and a ball valve disposed in the inclined chamber adapted to assume a lowered open position by force of gravity and operable to an elevated closing position when the pressure of fluid flowing downwardly through the divided chamber and the inclined chamber exceeds a predetermined degree.
3. In a valve of the character described, an angular body having vertical transversely oifset ports, the interior of the body defining an upper inlet chamber and a lower inclined chamber communicating with a passage in the body, a web in the upper chamber dividing the same to provide a main inlet passage and a by-pass channel, and a ball valve movably mounted in the inclined chamber adapted to assume an open position in the lower portion of the chamber when the fluid admitted to the valve is below a predetermined pressure and to be automatically adjusted to a closing position in association with the passage when the pressure attains a predetermined point.
