This invention refers to an attachment for valves the non rising stern type, a type which plained in the following specification.
-ans of this attachment a valve of the sing stem type can be closed from any distance, which means a great security in s where inflammable substances have to be controlled and where there is danger of a fire, for instance with petroleum, gasoline, kerosene, gases, etc. etc. in such cases or" fire the valve as actua v existing cannot possibly be closed by hand. lviany fires in oil wells could have been avoided if it had been possible to close the valve distance. 31'; The characteristic details of the attachment described in the following specification With reference to the accompanying drawings, in which the same numbers of reference indicate the same pieces in all the figures.
:31) In said drawings:
Fig. l is a front view of a non rising stem valve as actually used.
Fig. 2 is a vertical longitudinal semi-crosssectional view of the same valve.
Fig. 3 shows the same valve provided with the attachment according to the present invention.
Fig. 4 is a vertical semi-cross-sectional view of the valve with the attachment.
Fig. 5 shows the attachment provided with the so pieces 12-34-5 and 6 which together serve for opening or closing the valve by hand and by means of the wrench 46 of Fig. 19, respectively after the said valve has been closed by the attachment and when it is possible to get near the valve.
Fig. 6 shows the valve provided with the attachment but without the pieces 123i-5 and 6 for operating the valve by hand, this being the manner in which the attachment should be to mounted in order to be operative at a distance by fiuid pressure.
Figs. 7, 8 and 9 show the pieces l23 and 4 for manually handling the valve, in three different positions:
is '7 being a front view of the unit.
Fig. 8 being a side view of the same.
Fig. 9 being a vertical semi-cross-sectional view of the same.
Fig. 10 shows the same pieces in a plan View w" the wrench 46, which serves for opening d closing the valve manually. The operation of the attachment is as follows: A valve of the non rising stem type cornprises the following: The stem 7 (Figs. 1 and 2) which opens and closes the valve gate 8 has, at
about the middle portion, a circular collar 9 which keeps the stern fixed to the body of the valve by means of the ri 1S 1% and 11 of the piece 12 and the piece 13 of the valve, in such a manner that the stem '7 cannot ascend nor descend but only rotate under the action of the wheel 15. The ascension or descension of the valve gate 8 for opening or closing the valve is effected by means of the thread i l of the stem '7 as the gate 8 is screwed on to said stem by means of the o5 threaded perforation in its upper part, in such a manner that, for instance, when the gate 8 ascends on the thread 14 of the stem 7 or descends in the same manner, the said stem will not partake in these movements.
In order to provide a valve of the non rising stem type with the attachment for control at a distance according to the present invention, the following has to be done:
The nut 18, the wheel 15 and stufiing box 17 are removed by means of the screws and nuts 2021 and 22, the piece 13 by means of the screws and nuts 23-2425 and 26, and the stem 7.
Once this operation has been finished, the stem 27 of the attachment for distant control is placed (Figs. 3, 4, 5 and 6) screwing its lower threaded portion into the threaded hole in the upper part of the gate 8 of the valve, as is seen in Fig. 4, and once the stem is placed, the body of the attachment is placed on the piece 12 or" the valve by means of the screws and nuts 23-24-25 and 26; the other end of the stem 2'? of the attachment is fixed by means of a nut 29 to the bridge 28, whereafter the stuffing box 30 is provided with stufiing material of convenient quality and tightened by the glands 31.
If it is desired to operate the stem manually, then the pieces 12-3 i5 and 6 are mounted, but as said before, those pieces should not be placed on the attachment when the valve is going 9.5 to be operated at a distance by fiuid pressure.
In order to operate the valve at a distance, the attachment must remain as shown in Fig. 6.
As will be seen in Fig. 4, the stem 27 of the attachment has no collar 11 as had the stem '7 of the original valve and which served the purpose of fixing the stem in the body of the valve, and consequently the valve is thereby converted into a valve of the rising stem type in which the opening or closing by means of the gate 8 is effected by the ascension or descension of the stem 27 like a piston, as the gate will remain firm on the lower end of the stem 27 by means of thread.
The attachment comprises the following pieces (Figs. 3-4-5 and 6) and operates in the follov ing manner:
The principal body is formed by two twin cylinders 32 held together by the base 33 and the brace 34. Inside the two cylinders are found two pistons 35 which move within the expansion chambers 36 of the cylinders 32; at the rear end of said pistons are connected the bars 37 which in turn are connected with the bridge 28 by means 0:" nuts 38. The pistons 35 are packed in the cylinders 32 by means of the stuffing boxes 40. The bars 34 are packed in the cylinders by means of the stuifing boxes 41 and the glands 42.
The attachment operates by pressure of water, gas, air, vapour or any other fluid element which is injected, from a distant point, into the expansion chambers 36 of the cylinders, from a pump or from a deposit, by means of a pipe line 43 which connects in the upper part of the cylinders 32. By the pressure of the said fluid element, the pistons 35 are operated and these communicate movement to the rods 37, the bridge 28, the stem 27 and finally to the valve gate 8.
In order to open or close the valve by hand, after it has been closed by the attachment or when there is access to the valve, respectively, the pieces 1-2--3-45 and 6 are mounted as shown in Figs. 3-4 and 5, and the air vents 19 are opened.
In order to open or close the valve by hand, a wrench 46 as shown in Fig. 10 is employed.
The pieces 1 and 2 are two clamps with supports which are held together by screws and nuts 4.- and which are fixed to the rims 47 of the attachment by means of screws and nuts 5 and 6. At the upper part of these clamps, and in their centre, there is placed a block divided in two halves and provided with inside thread which corresponds to the thread of the stem 27 of the attachment. The divided block 3 remains fixed on the clamps 1 and 2 by means of the rims 44: and 45 and can only turn for raising or lowering the stem 2'7 which controls the valve gate.
Having thus described my invention, what I claim is:
1. An attachment for closing from a distance valves of the type having a stem threaded in a gate and held against axial movement in the valve casing, comprising a base arranged on the top of the casing, two cylinders carried by said base, pistons in said cylinders, a rod connected to the upper end of each piston and projecting from the cylinders, a bridge piece connecting said rods, a pipe adapted for conducting fluid under pressure to said cylinders, an elongated stem for replacing the original stem and having the lower end thereof threaded and fitted in the valve gate, and means connecting said elongated stem with said bridge piece.
2. An attachment as claimed in claim 1 characterized by the provision of a two-part internally threaded block embracing the upper projecting portion of the elongated stem the elongated stem being threaded at the point of engagement with said block, a two-part support 1- embracing and maintaining the parts of the block in operative position and secured to said base, and means for engaging and turning said block to adjust the gate.
