Definitions
- the present invention relates to a check valve for liquid gas container containers, which is one of the type installed in the mouth of liquid gas container containers for industrial and domestic use, especially in camping.
- These check valves are constituted by a support box, also called sealing or spring boxes, which is fixed by welding and, more frequently, by threading to the mouth of the container of liquefied gas container, which support box incorporates a shutter ball which, requested by a spring, is tightly applied against a sealing seat provided in the same box.
- This type of check valves pose certain problems, when used in an unprotected environment, due to deposits of dirt on the mouth or in microcavities caused by oxidation or chemical attacks of atmospheric agents that act in the visible part of the shutter ball.
- the ball rotates randomly and can be placed in a position where part of its surface affected by dirt or oxidation is applied against the seat joint, resulting in defective sealing points that cause leaks that are impossible to repair, which forces the container to be emptied and to replace the check valve that presents the leak, which implies an important economic cost.
- the solution that the shutter ball is always applied by the same spherical area against the sealing seat has been adopted, for which means are provided that allow the ball to move without produce no rotation of it.
- the check valve object of the invention has been developed which is essentially characterized in that the ball shutter has a slide appendage that is perpendicular to the sealing plane and presents a straight section that prevents its rotation and that coincides, in sliding form, with a guide window practiced at the bottom of the support box.
- a feature of the invention of a optional nature, which allows the use of a cleaning tool in the area of the ball, the shutter normally applied against the sealing seat, is that the support box, in its threaded mouth for the insertion of The regulating valve or flywheel tap and above the shutter seat for the ball shutter, has a flexible conical laminar seal, which allows access to the ball shutter.
- Another feature of the invention related to the possibility of cleaning said seat area, is the provision of a cleaning tool by means of which the ball shutter is accessible, through the flexible conical laminar joint, by a elastically flexible mouthpiece of a cleaning tool, which adapts to a spherical area of the surface of the shutter ball that corresponds to that said ball is applied against the sealing seat, all thanks to the thrust exerted on the shutter of ball by means of a pusher device that, overcoming the action of the spring, separates the ball from its seat, seals the space cooperating with the flexible conical laminar joint and communicates a rotation to said elastically flexible mouthpiece with which it rubs the shutter ball.
- the elastically flexible mouthpiece of the cleaning tool forms a tubular end portion of an elastic body axially pierced by a push rod which, at an outer end, ends at a centered thrust tip. of the ball shutter and, on the other inner end, it is requested by a spring that is applied against a regulating nut threaded therein, said rod running through a guide body fixed to a box in which a spring requests a Walloon of a mobile duct through which the said guide body and elastic body slide and with which the flexible truncated conical laminar seal is closed.
- Figure 1 represents a side elevation view of a check valve incorporating the object of the invention.
- Figure 2 represents a section along the line ll-ll of Figure 1.
- Figure 3 represents a section along the line lll-lll of Figure 2.
- Figure 4 represents, partially sectioned according to a diametral plane, a cleaning tool suitable for the check valve of the invention.
- Figure 5 represents the cleaning tool of figure 4 in working position in a check valve like that of figure 1.
- a check valve 1 is represented which is substantially constituted by a support box 2, a ball shutter 3 and a spring 4.
- the support box 2 in the case represented as an example of the invention in the drawings, is constituted, as illustrated in Figures 1 to 3, by a fixing body 5 associated with a spring body 6.
- the aforementioned fixing body 5 consists of a bushing which has: a manipulation wall 7, which allows the assembly and disassembly of the check valve 1 in the threaded mouth of a container of liquefied gas thanks to its periphery having facets 8, crenellated or other provisions that allow the use of a manipulation tool, such as a fixed wrench, an adjustable wrench, etc .; a threaded outer portion 9, for insertion into said threaded mouth; an outer step 10 for seating a seal 11; a threaded inner portion 12, for the insertion of a flywheel tap; a first inner step 13 for the seat of a flexible frustoconical laminar joint 14; a second inner step 15, below the above-mentioned step, for seating a seat joint 16 for the ball shutter 3; and an interrupted step 17 for engaging and fixing the spring body 6 by means of a bayonet arrangement.
- a manipulation wall 7 which allows the assembly and disassembly of the check valve 1 in the threaded mouth of a container
- This cited spring body 6 has axial ribs 18 flanked by walls 19 and windows 20, while those axial ribs 18 and walls 19 meet, superiorly, in an interrupted ring 21, which cooperates with the interrupted step 17 to constitute a bayonet-type lace arrangement, and, inferiorly, on a bottom 22.
- the ball shutter 3 comprises a ball 23, proper, which has the particularity, object of the invention, that incorporates a slide appendage 24 capable of sliding through a guide window 25 provided on the bottom 22 of the spring body 6 , which slide appendix 24, in turn, also presents the peculiarity that its straight section is such that it does not allow axial rotation, which contributes to the fact that said guide window 25 is duly complementary thereto.
- the containers of liquefied gas that mount the check valves 1 of the invention may be cleaned of the balls 23 of their shutters by means of a cleaning tool 27, such as that shown in Figures 4 and 5.
- a cleaning tool 27 such as that shown in Figures 4 and 5.
- cleaning tool 27 in the rest state, in figure 4, and in the use state, in figure 5.
- Said cleaning tool 27 comprises a head 28, provided with a holding rod 29 to a support not shown, which houses to a fixed assembly formed by a jacket 30 and a guide body 31, both simultaneously held by two opposing screws that cross them together with the head 28, of which the jacket 30 has an inner wall 33 and the body of guide 31 has an axial duct 34 in which a pusher rod 35 is housed which, at one end, includes a nut 36 and a spring 37 and, at the other end, has a retaining head 38 and a thrust tip 39.
- a mobile duct 40 which has a seat wall 41 on the inner wall 32 of the jacket 30, houses the guide body 31 and a elastic body 42 that determines an elastically flexible mouth 43, said mobile duct 40 being requested by a spring 44.
- the cleaning tool 27 is inserted into the mouth of the fixing body 5 by being applied by the end of the body of guide 31 against the flexible conical laminar joint 14, to seal the space while moving the ball 23 of its seat with the push rod 35 against the seat joint 16 overcoming the action of the spring 4 and with the elastically flexible mouth 42 it adapts on the surface of the spherical area 26 of the ball 23, at which time some turns of the cleaning tool 27 are made, so that any impurity of said spherical zone is rubbed off, after which, when removed the cleaning tool 27, the ball 23 is applied again against the seat joint 16 by its spherical zone 26 of origin, preventing any foreign element from being intercalated r between the ball 23 and its seat seal 16 to result in a gas leak.
