Description
March 26, 1935. J. BELANGER 'ET AL GONDUIT VALVE FOR PAPER PULP LINES AND THE LIKE Jwucntow Filed NOV. 23, 1931 Patented Ma. 26, 1935 THE LIKE 7 Joseph Belanger and Ernest Durnin, Escanaba, Mich.
Application November 23, 1931; Serial N s'ie'eso 3 Claims. (01. iev issq' Our invention relates to improvements in con duit systems for paper pulp and the like and has particular reference to a; novel valve means .for controlling the flow of the pulp in its passage from one treatment tank, or instrumentality 1130 another.
In paper mills the .pulp conduit system.neces'-, sarily includesanumber of valves for controlling the flow of pulp.- ,For instance, in the case of the stock or pulp line leading from thestock tank above the .battery of beaters is provided with a separate branch leading down to the respective heaters and intermediate the -ends of such branches are placed gate valves for controlling the supply of pulp toa particular beater.- The use of gate valves, and particularly intermediate the ends of the branch lines as aforesaid, is very ob jectionable. In the first place the portion of the. branch line between the valve and the stock line serves as .a pocket for catching and receiving the pulp when the valve is closed; 'Not only this, but the pitch and other matter in the pulp very soon gums upthe gate valves or plug valves ,to
such an extent that they cannot be -operated,it
" being common knowledgethat such valves must be cleaned approximately every forty-eight hours. Inasmuch as mostmills have four or five stock lines disposed over the heaters so that'stocks of variouscharacter can be fed-thereto, or mixeconomy in space above the heaters becomes an important item. The gate valves take up considerable lateral space ,and reduce considerably the number or stock lines that-can be ,accommodated above -.a given beater. Furthermore, the IOCatlOIYOfl the gate valves intermediate the ends of the branches leading .trornthestocl; lines to the beater constitute an additional fitting over and above the T-fitting whereby the branchlinc is connected to the stock line;
It is, therefore, the primary vention to overcome the objections aforen'oted and to provide in a paper pulp conduit system or the like, a novel valve which may be incorporated in the stock line, for instance, in lieu of a T- fitting for supporting the branch lines whichlead to the beaters,thus saving the expense of a special valve fitting and efiecting a great economy of lateral space above the beaters so that the maximum number of stock lines may be employed without crowding.
More specifically, it is an object of the inven tion to provide a novel valve for the purpose specified which will be automatically cleaned by the passage of the pulp through the conduit and tures of several diflerent stocks, '-the matter of.
object'of our in which will not in any way impede the flow of pulp. .-A further'object of the invention is .to provide a valve as characterized, incorporating a noveloperating means'which' is susceptible of relativead- 1 justme'nt ,with respect tofthelgyalve'.casing the invention contemplating inz'addition .a valvejsusceptible ofaboth manual andflmechanical opera: tion. The invention also residesin certain novel features of construction, combination andlarrangement of the various parts and incertain modes'of operation as will'be readily apparent to those skilled in the art-upon reference to. the accompanying drawing in connection"with the detailed-descriptive matter appearing hereinafter. 15 It is to be understood --that the disclosures herein depict what are now'regar'ded' as preferred forms of thelinventi'on. However, it :will beobyio'us-that various changes and'modifications maybema'de without departing from the spirit 9 and scope of the subject matter claimed hereinafter.
the drawing, wherein' ithe same reference characters have been-.used to designate the same parts in allviews, j
Figure. 1 is a" vertical sectional view taken through a valve 'casingand illustrating, our invention in the phase which contemplates hydraulic-or pneumatic operatingmeans, and n Figure 2 is anielevational view illustrating the application of the invention'to'the" stock line and branch which supplies the paper pulp to the beater. s
Referring specifically to the drawing, numeral 5 denotes the valve casing which, as will be 010- 5 d served, has the form of a T-coupling having end flanged outlets 6, a bottom flanged outlet 7, but which has a top neck or outlet 8 provided with the disk or closure 9 which'may be boltedor clamped to such neck or outlet'8 inthe usual or in any preferred manner.. r v 1 1 The closure-plate9'is provided with a medial bearing carrying'theV-packing gland assembly 10,. providing a guide and seallfor the valve stem 11, carrying at its lower end the disk-like head 45 12, which is provided with a medial recess at its rear face for receiving the headed end 11a of the valve stem upon which is superposed the washer 13. The clamp nut, or bushing, 12: is threaded in the recess of valve 12 and securely holds the valve and stem assembled.
Figure 1 discloses, very clearly the novel insert, or liner, bushing 14 which is adapted to be inserted into the bottom outlet '7 of the valve casing 6. V In this connection it isnoted that the upper 5 end of the liner bushing 14 provides the seat 14a for the valve 12,such seat extending below. the plane of the conduits 6, 6 through the valve body 5.
Especial attention is directed to the formation of the valve or head 12,it being noted that its upper surface is fustro-conical and slopes very gradually in the direction of the periphery of the valve head. Thus, the pulp flowing through the stock line A (Figure 2) will serve to effectually clean the valve head 12, which forms no obstruction to the passage of the pulp.. Obviously, the
is less than the major diameter of the bonnet orsupport 15 and serves as a keeper or guide within-whichthe cylinder 18 is adjustably supported, Set screws 17a 'arepreferably used for maintaining the cylinder 18-.in a desired relative adjustment with'respect to the guide memberl'l.
Within the cylinder 18 works the double acting piston 19 comprehending the oppositely directed leather cups, and other conventional features of construction, which, are clamped against the shouldered end 11b of the valve stemll by means of the nut 20.1 Springs 18a and-18h assist in operation of piston 19. I
The upper end --of the cylinder .18 is closed. by the cap 21, which has the tapped inlet 22 which is adapted to receive the pressure fluid conduit or pipe 22a. 1 i
The lower end of the cylinder 18 is provided with a closure cap23 which is threaded thereon and has the medial bearing 23a which with the packing gland nut 25 and filler provides a seal and guide for the stem,--.-preventingas will be obvious, the escape of the pressure fluidfrom the cylinder 18. The closure 23 has the Having thus described om invention; what'we claim as new and desire to secure by Letters Patent is: *5 15;
