Specicaton of Letters Patent.
Patented Jann, 1919.
Application led April 13, 1918. Serial No. 228,4(19.
TQ all whom zt may concern:
Be itknown that I, BUizQHARD THoENs, a citizen of the United States;v and resident of New York, New York county, State of New York, have invented certain new and usefuln Improvements in Equalizing- Valves, of which the following is a specification.
This invention relates to equalizing valves for use inconnection with pumps for handling volatile liquids. i It is well reco ized in pumping volatile fluids that conslderable trouble is caused from the vapor or gases which are present or given olf from the liquids. These' gases are the cause of hammering in the operation of the pump and also reduce the volumetric -eiiiciency of the same. It is the object of this invention to provide a valve which Will eliminate these defects; to provide such a valve which is of exceedingly simple construction, will operate 'indefinitely without wear, requires practical] no attention and is built so that it can be dlsassembled quickly and easily.
Other objects and features of the invention will be apparent from the description taken in connection with the drawings, in which- Figure 1 is an elevation view showing a portion of a pump in section, the liquid receiver connected therewith and illustrating the llocation of my improved equalizing inder and receiver; and
Fig. 2 is a sectional elevation through the equalizing valve.
Refe to the drawin 10 indicates a receiver whlch maybe supp ied with a volatile fliquid such as ammonia, hot water or sweet water and syrup from defecating pans, throughv the pipe 11.` The inlet chamer 12 of the pump 13, is supplied with volatile liquid from the receiver by means of the pipe 14. The iiow of the Huid from.
the inlet chamber 12 into'the pump cylinder 15 is controlled by means ofthe valves 16 and 17, the valve 16 being arranged in the valve chamber 18 and the valve 17 bei located ilrthe valve chamber 19. The luld is discharged from the pump cylinder 15 through the discharge valves 20 and 21 into the discharge chamber 22, which is in communicaton with the discharge pipe 23. The
pipe 24 is threaded `into the highest portion ofthe valve chamber 18 arid a similar pipe 25 is threaded into the lnghest portion of with the pump cyl- .valve controlling the o ening the valve chamber 19. These pipes lead t0 my improved equalzing valve 26 being connected to the same on oppositesides thereof. The pipe 27 leads from the top of the equalizing valve and is connected tothe receiver :near the top thereof.
As shown in the drawings the equalizing valve comprises a housing 28 which may be formed with a boss 29 into which the pipe 27 is screwed. The wall of the housing opposite this pipe consists of a removable plate 30 which 1s formed With the spaced openings 31 and 32. The opening 31 is formed with a valve seat 33 and the opening 32 with a like valve seat 34. Theplate' 30 in addition to forming a `Wall for the housing 28 also forms a wall forv a second housing 35. This latter housing is provided with a partition 36 which divides the same into two chambers 37 and 38. The pipe 24 is in communication with the chamber 37 and the chamber in turn is in communication with the interior of the housing 28 through the opening 31.
, The pipe 25 is connected into the chamber 38 and the chamber is in communication with the interior of housing 28 through the opening 32. The two housings and the interposed plate 30 may be securely clampedtogether by the boltst39. 'An arm 40 is arranged within the housin 28 bein pivotally mounted on a short s aft 41. woted to one end of this arm is a spindle 42 which has a valve disk43 threaded on its lower end, said diskbeing located in the chamber 38. The other end of the arm-has a similar spindle 44 pivoted to the same which at its lower end has threaded thereon a valve disk 45 located within the chamber 37. The valve disks 43 and 45 have spherical surfaces which coperate with the seats 34 and 33 respectively, to close the openings 32 and 31.
In the operation of the device if the piston of the pump is moving toward the left 25 will cause the valve to close the opening 32 thus rocking the arm 40 and opening. the 31. Thus communication is established between the right hand end of the pump as viewed -in j Fig. 1 and the receiver. This vvillpermit the iiuid to iiow from the receiver into the said end of the pump, thereby e elling any gas which may be 1n the cylin er through the pipe 24, equalizing valve and pipe 27 into the top of the receiver. It will bev apparent that in this manner the pumps-cylinder will be filled with liquid, all of the gases having been expelled so that the pump will operate at a maximum volumetric efficiency and there will be no hammering of the same. When the direction of movement of the piston is reversed a similar operation of the parts occurs in connection with the other end of the cylinder.
lt will be apparent that I have provided a very simple valve which is practically free from wear as there is no sliding movement. The valves are opened and closed by the rocking of arm on the shaft 41 and it is obvious that this rocking movement can go on almost indefinitely before there is any derangement of the valve due to Wear. Even if after a long period of operation a looseness should develop, the valve will operate perfectly because of the disks having the spherical surfaces and because they are carried on the pivoted spindles, this construction permitting the valves to always adjust` themselves to the seats.
Although I have described an embodiment of the invention specically it is apparent that details thereof may be varied to a considerable extent without departing from the spirit of my invention.
Having thus described my invention what is claimed as new and desired to be secured by Letters Patent is l. An equalizing valve for pumps including a housing having an outlet and two openings each formed with a valve seat, a second housing secured to said first housing Leeaeee having a partition dividing the saine into two chambers7 each chamber being in communication with the interior of said first housing through one of the said openings and each chamber also having a connection for a pipe, an arm pivoted in said first housing, each end of the arm having a spindle pivoted thereto which extends through the adjacent opening in the housing, and, a valve disk on the end of each of the spindles within the associated chamber arranged to coperate with the seat around the corre'- sponding opening.
2. An equalizing valve for pumps including a housing having an outlet and two openings in one wall thereof each formed with a valve seat, a second housing secured to said first housing having a partition dividing the same into two chambers the said Wall also forming a wall for the second housing each chamber being in communication with the interior of said first housing through one of the said openings and each chamber also having a connection for a pipe, an arm pivoted in said first housing, each end of .the arm having a spindle pivoted thereto which extends through the adjacent opening in the housing,and a valve disk on the end of each of the spindles within the associated chamber arranged to coperate with the seat around the corresponding opening.
In testimony whereof I aiiix my signature.
