. clear, and exact description.
This invention relates to valves and particularly to an improved valve for hot water heating systems and has for an object to provide an improved structure wherein an improved form of holding member for the valve is provided.
Another object of the invention is to provide a holding or looking sleeve for the key or sleeve of the valve.
A still further object of the invention is to provide a valve for hot water heating systems wherein a sleeve or locking nut coacts with the stem of the valve for locking the key or sleeve of the valve in proper operative position while allowing the same to freely rotate.
In the accompanying drawing- Figure 1 is a longitudinal vertical section through a valve disclosing an embodiment of the invention.
Figure 2 is a perspective view of the key or sleeve of the valve together with its controlling stem.
Figure 3 is a. perspective view of the looking sleeve or look nut shown in Figure 1.
Figure 4 is a section through Figure 1 approximately on line 44.
In valves for hot water systems as provided heretofore, a rotating internal sleeve is utilized as a .key or valve member for turning on and off the water. Difiiculty has been found in properly supporting this key' or valve member and various devices used to accomplish the desired result. In the present invention, means have been provided which will positively hold or look the internal sleeve in correct position without interfering with its proper rotation.
Referring to the accompanying drawing by numerals, 1 indicates the casing of a valve which is provided with an inlet 2 and an outlet- 3, said casing being formed with an upwardly extending section 4 for receivin the packing nut 5 which surrounds the va ve stem 6. The section 4 has a clownwardly facing shoulder 4 for a purpose hereinafter described. The casing 1 adjacent the upper end of the bore carrying the internal sleeve 7 is provided with a pair of lugs or enlargements 8 and 9 which act as stops for the. lug 1O projecting from the upper end of the sleeve 7. .It will be noted that the sleeve 7 is. provided with a main opening 11 and a small aperture 12 designed to permit the passage of a small quantity of water when the valve is closed so that there will be some circulation water in the heating system to prevent freezing in radiators during extremely cold weather. Extending upwardly from the sleeve 3 is a valve stem 6 integral therewith and provided with an enlarged lower end 6" having an upwardly facing shoulder 6 for engaging the shoulder 4 of the section 4, when the valve is open, so as to prevent the passage of water into the projection, and thereby reducing the likelihood of leakage.
' The stem 6 is provided with a threaded sec tion 13 adapted to co-act with the internal threads of the nut or locking sleeve 14 which is externally threaded for co-acting with the internal threads forming section 4, which section is internally and externally threaded. The upper end of the locking sleeve or nut 14 is provided with a tapering portion 15 adapted to receive suitable packing 16, said packing being clamped properly in place by the nut 5.
When the valve is disassembled and it is desired to assemble the same, the sleeve 7 is inserted into the casing 1 until it strikes against the upper end of the casing with the lug 10 between the respective lugs S and 9. The stem, lock nut or locking sleeve 14 is then screwed into place uniting the stem 6 with the portion 4 of easing 1 by reason of the two sets of threads as heretofore described. It will be understood that the stem, lock nut or lockingsle'eve 14 is provided with threads of the same pitch interiorly and exteriorly whereby it may be properly positioned as just described. The packing 16 and nut 5 are then arranged as shown in Figure 4 and the valve is in condition for use.
When the cylinder or sleeve? is assembled, the opening 1.1 is preferably held in line with the inlet 2 but when the sleeve or cylinder 7 is rotated for half a revolution, the valve will be closed though a bleeding action will be allowed by the aperture 12. As the threads on the locking nut or sleeve 14 are small, the amount of longitudinal movement of thecylinder or sleeve 7 will be very small and, consequently, will not be noticeable in the operatlon of' the valve. It will be noted that the cylinder or sleeve 7 is open at one end while it issupported by the stem, lock nut or sleeve 14 at the opposite end which does not in any vvayinterfere with the proper opening and closing of the valve while presenting an extremely simple and eflicient construction.
What I claim is':- y v A hot water valve, comprising a casing having inlet and outlet openings and pro vided with an integral tubular projection at its upper 'end, said projection being internally and externally threaded and having an annular internal and downwardly facing shoulder at its lower end, a cylindrical valve 7 rotatably mounted in the casing and havin inlet and outletepenings,said valvc being provlded with an-integral stem hav- 7 ingan enlarged lower end extending into said 7 promotion of the oasmg and having an annuar and upwardly facing shoulder engaging the shoulder of the casing when the valve is open, said stem being threaded adjacent the said enlarged endyan internally and externally threaded sleeve screwed onto the stem of the valve and into the projection of the casing, said sleeve being provided with a flange having aconcave outer face, aflanged nut screwed onto the pro'ectio'n and through which the stem prqects, and a packing between the flange of the sleeve and the nut.
