Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Referring to Fig. 1 and Fig. 2, the ball shape flow limit valve of present embodiment comprises a valve body 1, a spherical valve core 2 and a valve rod 5, forms the valve pocket of perforation in the valve body 1, and spherical valve core 2 is installed in the valve pocket of valve body 1, and valve pocket is divided into inlet opening 3 and liquid outlet opening 4.Valve rod 5 is installed on the described valve body 1 rotationally, and handle 6 is installed on the valve rod 5, and handle with sleeve 6 can drive spherical valve core 2 and rotate between open position and rest position.Radially inwardly form an outstanding boss on the inwall of spherical valve core 2 near the endoporus of liquid outlet opening 4 one ends, form a kind of shoulder shape.In the bigger endoporus of the internal diameter of spherical valve core 2, fix a current limiting element 7, this current limiting element 7 is a hollow cylinder, this current limiting element 7 is fixed by the boss of moulding in spherical valve core 2 endoporus near an end of liquid outlet opening 4, fixedly snap ring 9 is fixing by being stuck on spherical valve core 2 endoporus two for the other end, here also can with other fixed structure such as seal ring or the back of the body cap fix, perhaps only fixedly snap ring 9 is fixing with one, all plays removably fixing effect equally.When also being provided with an endoporus of checking that mounting hole 8, the position of this inspection mounting hole 8 are in spherical valve core 2 on the valve body 1 and being positioned at rest position on the valve body 1 of correspondence.During proper functioning, this inspection is changed hole 8 usefulness and is sealed with the blind plate 10 that valve body 1 is tightly connected, thereby avoids some liquid to spill from this inspection mounting hole, influences production process.When the needs inspection or when changing described current limiting element 7, embodiment is rotated counterclockwise 90 degree with handle 6 as shown in Figure 3, and the inlet opening 3 of current limiting element 7 is alignd with an inspection replacing hole 8, makes ball shape flow limit valve be in rest position; Open blind plate 10 subsequently, take out fixedly snap ring 9 and current limiting element 7 and check.In actual applications, described current limiting element 7 is one group of universal accessories, and this group current limiting element has the metering hole of same form structure and different size diameter.Can change the current limiting element of different size like this according to changes in flow rate; Current limiting element that will check at last or that need replace with reloads in the spherical valve core 2, refills fixedly snap ring 9, installs blind plate 10 at last, and handle 90 degree that turns clockwise makes ball shape flow limit valve be in open position to resume work.
Referring to Fig. 4, the present embodiment remaining part is identical with embodiment 1, difference be the current limiting element 7 that adopts be one with spherical valve core 2 endoporus on the corresponding hollow cylinder that has shoulder of boss structure, also fixedly snap ring 9 is fixing with one or two for one end of these current limiting element 7 close inlet openings 3, also can fix with other fixed structures such as seal rings, the other end is then fixed by the boss on the spherical valve core 2.
Referring to Fig. 5, the present embodiment remaining part is identical with embodiment 1, and difference is do not have the moulding boss in the endoporus of the spherical valve core 2 that adopts, is a cylindrical hole that endoporus is isometrical; The current limiting element 7 that adopts still be a hollow cylinder, and at this moment the two ends of current limiting element 7 all use the fixedly snap ring 9 on the inwall of the endoporus that is stuck in spherical valve core 2 to fix, also can be all with seal ring or carry on the back other fixed structure such as cap and fix.When checking or change current limiting element, only need take out fixedly snap ring 9 fixed structures such as grade of inlet opening 3 one ends, and needn't take out fixedly snap ring 9 fixed structures such as grade of the other end.
Referring to Fig. 6, the present embodiment remaining part is identical with embodiment 1, difference is that the endoporus of the spherical valve core 2 that adopts is a conical bore, the current limiting element 7 that is adopted is corresponding hollow cone with it, fixedly snap ring 9 is fixing with one or two for the bigger end of current limiting element 7 external diameters, and the other end is directly fixed by the hole less than the current limiting element minimum outer diameter of spherical valve core 2.
