  • the valve is also adapted to [56] Reerences Cited facilitate the evacuation of products reverting from a decoking of a distillation column without opening the valve during UNITED STATES PATENTS the processing or cracking gas of petroleums under high temerature.
  • the present invention aims at overcoming this inconvenience.
  • a direct sluice valve of the type comprising a sliding closing member with parallel faces characterized in that it comprises means for protecting the seatings of its closing member against the injurious action of the conveyed fluid, when it is in the open position.
  • the closing member is associated with a wedge for pressing the closing member against its seating, said closing member being provided with an extension in which there is provided an opening for the products conveyed so that in the open position of the valve, due to sliding displacement of the closing member this opening is situated between the inlet and the outlet orifices of the valve, the aforesaid wedge having itself an identical orifice so that it can be applied against the closing member when the latter is in the open position as well as when it is in the closed position.
  • the wedge and the closing member are of course connected in vertical translation to independent members for controlling their vertical displacement, and permitting unwedging and rewedging of the closing member respectively before and after each displacement.
  • the closing member comprises in its part ensuring the closure of the inlet orifice of the valve, a blind central bore which with longitudinal axis parallel to the direction of flow of the products, communicates with a seating made in the said closing member and leading laterally from the latter to an additional outlet tube provided in the body of the valve in order to permit the evacuation of products resulting from the decoking of the distillation column or furnace without opening the valve.
  • decoking of an installation disposed above the valve may be effected in that it is unnecessary to open the valve and consequently without it being necessary to stop the installation.
  • the closing member is mounted with lateral play in the body of the valve and carries on one of its lateral faces an inclined surface which at the end of the closing stroke and in combination with an oppositely inclined surface inserted in the body of the valve, places the other lateral face of the said closing member against the seating made at the inner end of the additional outlet tube for the decoked products.
  • FIG. 1 is a part-sectional perspective view showing a first embodiment of the valve
  • FIG. 2 is a cross-section of part of the valve of FIG. 1, more particularly a closing member in the closed position;
  • FIGS. 3 and 4 are sectional views taken respectively on lines 3-3 and 4-4 of FIGS. 4 and 3, showing, on an enlarged scale, another embodiment of the invention.
  • the valve shown in FIG. 1 is essentially constituted by a tubular body 2 of rectangular section and having on two of its opposite lateral walls two tubes 3 and 4 respectively having inlet and outlet openings 3aand 4a.
  • a vertically disposed cover 5 Inside the tubular body 2 of the valve there is disposed a vertically disposed cover 5. Beyond its part ensuring the closure of the inlet opening 3a, there is an extension 5a in which is made a bore 6 of equal diameter to the inlet orifice 3a in the tube 3.
  • the cover 5 is connected for vertical movement to a rod 7 capable of being reciprocably displaced vertically by any known means.
  • the cover 5 is associated with a wedge 8 having a vertical flat face 84 disposed adjacent one face of the cover 5, and an inclined face 8b which, having a steep slope, is supported in the closed position of the valve, against a seating 9 made in the body of the valve.
  • This wedge is provided with a cylindrical bore 10 of diameter equal to that of the inlet and outlet orifices of the valve.
  • the wedge 8 is connected for vertical movement to an operating rod 12 being capable of being reciprocably displaced vertically.
  • cover 5 and the wedge 8 have on their faces adjacent their seatings, radial grooves, not shown in FIGS. 1 and 2, intended to permit cleaning of the corresponding seatings by steam under pressure which is led into the tubular body 2 and which is evacuated through the outlet tube 4.
  • This steam prevents any carbonaceous or tarry particles from being deposited on any of the seatings or on the cover or the wedge and thus avoids any trouble or operating accidents ensuing from deposition of such particles.
  • the cover 5 has in its part assuring the closing of the valve a truncated blind bore 15 which, coaxial with the inlet and outlet openings 3a 4a, leads into a blind seating 16.
  • This seating 16 extends laterally and emerges on one side edge of the cover 5 adjacent an outlet tube 17 made in the corresponding wall of the tubular body 2.
  • the side edge of the cover 5, opposite that coming in contact with a seating 17a made at the inner end of the tube 17, comprises an inclined plane or wedge 18.
  • the tubular body 2 has on its innerface adjacent the wedge 18 an inclined slope 19 which has an inclination opposite to that of the wedge 18.
  • the cover 5 has lateral guide clips 20 which are spaced slightly from the corresponding inner walls of the tubular body 2 in order to allow the cover 5 a certain lateral play .I.
  • the valve thus realized of the direct three-way type is particularly useful when it is used for the conveying of products coming from a distillation column or a furnace. in fact, when it is in the position shown in FIGS. 3 and 4, that is to say in the closed position, it can be adapted to evacuate the products coming from decoking of an installation below which it is disposed.
  • the decoking products entering the valve through the inlet tube 3 pass directly through the bore 15 and seating 16 to be evacuated through the tube 17.
  • valve is particularly suitable as it permits decoking with the valve in the closed position, while in the past it has been necessary to leave the valve in the open position which made it necessary to stop the installation completely before carrying out the decoking.
  • the valve according to the invention therefore, it is not necessary to stop the distillation column for a long time in the order of three to four days. in fact a reduction of the temperature in the distillation column or in the furnace, which only requires a few hours, is sufficient.
  • Such a valve therefore, permitting the considerable reduction of the stopping time necessary for decoking of the installation on which it is installed, consequently provides a considerable increase in the output of the installatron.
  • FIGS. 3 and 4 show more particularly the tubular body 2 is surmounted by a box 26 having cooling vanes 27 and an inlet tube 28 which is connected to a steam system under pressure.
  • the box 26 has seatings 29 for the stuffing boxes intended to ensure a water-tightness for the passage of the control rods 7 and 12 respectively of the cover 5 and the wedge 8. ln known manner these two rods are connected to means for imparting to them vertical movement.
  • tubular body 2 has at its lower part a removable box 33 intended to receive the products of decoking or the carbonaceous and tarry particles which would not be evacuated normally through one of the outlet tubes 4 orl7.
  • the box 33 may be removed from the tubular body 2 so as to be emp tied of the deposits which it contains and this can be done when the valve is in the open or closed position.
  • a sluice valve for pipes conveying products at high temperature of the type comprising a gate having two laterally extending parallel faces, a laterally extending bore fonned in said gate, a body having coaxial conduits for respectively the inlet and outlet of the product being conveyed through said valve, an auxiliary outlet conduit in said body communicating with said laterally extending bore, said gate being slidably positioned in said body intermediate said conduits for separating the latter, said gate having an orifice adapted to provide product flow communication between said conduits in a valve open position, said gate further including, in the portion thereof spaced from said orifice and providing leak-proof separation between said conduits, a centrally located blind ho e extending parallel to the flow of said product and communicating on one side with the inlet conduit and at the other side with said auxiliary outlet conduit, a wedge in said body extending adjacent to said gate, independent actuating means for displacing said wedge relative to said gate in parallel movement, said wedge having a central aperture, said actuating means effecting herm
  • a valve according to claim 1 characterized in that the gate member is mounted with lateral play in the body of the valve, there being provided an inclined surface on one of its lateral faces which at the end of the closing stroke and in combination with an oppositely inclined surface made on the body of the valve, places the other lateral face of the said gate member against a seating made at the inner end of the auxiliary outlet conduit.
