Description
Technical field
The utility model relates to a kind of valve technology field, is specifically related to a kind of floating ball valve.
Background technique
Floating ball valve is a kind of valve products, and closed circuit device made by the pipeline being widely used in water, rock gas, coal gas, liquefied petroleum gas and oil refining, airport, chemical industry, Oil & Gas Storage etc.
Valve rod and the sealing configuration between valve body of traditional floating ball valve mainly adopt stuffing box packing assembly to be connected by the mode of fastening nuts, this structure existing defects, if nut loosening, sealing effect will reduce, and causes stuffing box packing assembly not have seal action.And existing stuffing box packing all adopts rigid common stuffing box packing, compression effectiveness is not good.When there being impurity to make in fluid, the rotation of spheroid can drive impurity scratch spherome surface, and spheroid can be wound, and causes fluid leakage.
Summary of the invention
The purpose of this utility model is: provide a kind of good sealing effect, and stuffing box packing assembly decrement is large, the floating ball valve that protection spherome surface is not scraped off.
In order to achieve the above object, the technical solution of the utility model is: a kind of floating ball valve, comprise valve body, with the spheroid of opening, valve rod, valve seat and end cap, end cap is fixedly connected with valve body, and form valve pocket, spheroid is positioned at valve pocket, one end of valve rod is stretched in valve pocket, and be fixedly connected with spheroid, valve seat has two, and lay respectively at the both sides of spheroid, and be fixedly connected with end cap with valve body respectively, valve body and end cap are respectively equipped with first passage and second channel, also comprise stuffing box packing assembly, butterfly spring, fastening piece, filler pressing, gland and indicator collet, stuffing box packing assembly, filler pressing and butterfly spring have lower supreme order to be sleeved on successively on valve rod, gland is fixedly connected with valve body by fastening piece, be tight against with butterfly spring, the seal ring that described stuffing box packing assembly is V-type by multiple cross section is formed by stacking, described valve seat and the position that contacts of spheroid are provided with annular every slag chute.
In technique scheme, between described end cap and valve body, be provided with seal ring.
Described fastening piece is screw, and butterfly spring has two.
The good effect that the utility model has is: the utility model is owing to adopting gland and butterfly spring structure, gland is fixed by fastening piece and valve body, gland can produce downward impacting force, make impacting force act on butterfly spring, butterfly spring remakes and is used in filler pressing, and pushes down stuffing box packing assembly, make stuffing box packing component strain, the sealing effect of stuffing box packing assembly is better, uses for a long time, also there will not be stuffing box packing assembly also to there will not be loosening phenomenon.And seal ring is formed by stacking because stuffing box packing assembly is V-type by multiple cross section, therefore after multiple V-shaped seal ring superposition, the decrement of bearing can become large, and its deformation effect is good, and sealing effect just improves further.Again because valve seat and the position that contacts of spheroid are provided with annular every slag chute, therefore when there being impurity in fluid, spheroid rotates and impurity will be brought into annular in slag chute, and avoid spherome surface to be pulled, fluid can not be revealed.
Accompanying drawing explanation
Fig. 1 is the structure sectional view of the utility model embodiment;
Fig. 2 is the I portion enlarged view of Fig. 1;
Fig. 3 is the K portion enlarged view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and the embodiment that provides, the utility model is further described, but is not limited thereto.
As Fig. 1, 2, shown in 3, a kind of floating ball valve, comprise valve body 1, spheroid 2 with opening, valve rod 3, valve seat 4 and end cap 5, end cap 5 is fixedly connected with valve body 1, and form valve pocket 1-1, spheroid 2 is positioned at valve pocket 1-1, one end of valve rod 3 is stretched in valve pocket 1-1, and be fixedly connected with spheroid 2, valve seat 4 has two, and lay respectively at the both sides of spheroid 2, and be fixedly connected with end cap 5 with valve body 1 respectively, valve body 1 and end cap 5 are respectively equipped with first passage 1-2 and second channel 5-1, also comprise stuffing box packing assembly 7, butterfly spring 8, fastening piece 9, filler pressing 10, gland 11 and indicator collet 12, stuffing box packing assembly 7, filler pressing 10 and butterfly spring 8 have lower supreme order to be sleeved on valve rod 4 successively, gland 11 is fixedly connected with valve body 1 by fastening piece 9, be tight against with butterfly spring 8, the seal ring that described stuffing box packing assembly 7 is V-type by multiple cross section is formed by stacking, described valve seat 4 and the position that contacts of spheroid 2 are provided with annular every slag chute 4-1.
Shown in Figure 1, be provided with seal ring 15 between described end cap 5 and valve body 1, adopt after said structure, the sealing contact surface of end cap 5 and valve body 1 arranges the sealing effect that seal ring 15 can effectively ensure between end cap 5 and valve body 1.
Shown in Fig. 1,2, described fastening piece 9 is screw, and mounting or dismounting are convenient; Butterfly spring 8 has two, adopts after said structure, and two butterfly springs 8 are superimposed use, and bearing capacity is high, and using effect is good.
Shown in Fig. 1,2,3, when the utility model uses, work as handle with sleeve, handle strip ovable valve stem 3 rotates, and valve rod 3 can drive spheroid 2 to rotate in valve pocket 1-1.Shown in Figure 1, after the opening of spheroid 2 and first passage 1-2 and second channel 5-1 connect, be then on state; Work as handle with sleeve, handle strip ovable valve stem 3 rotates, and spheroid 2 is rotated 90 °, be then closed condition.The utility model is owing to adopting gland 11 and butterfly spring 8 project organization, gland 11 is fixed by fastening piece 9 and valve body 1, gland 11 can produce downward impacting force, make impacting force act on butterfly spring 8, butterfly spring 8 remakes and is used in filler pressing 10, and pushes down stuffing box packing assembly 7, stuffing box packing assembly 7 is out of shape, the sealing effect of stuffing box packing assembly 7 is better, uses for a long time, also there will not be stuffing box packing assembly 7 also to there will not be loosening phenomenon.And the seal ring that described stuffing box packing assembly 7 is V-type by multiple cross section is formed by stacking, and in reverse V-shaped layout, the decrement of bearing can become large, and its deformation effect is good, and sealing effect just improves further.Described valve seat 4 and the position that contacts of spheroid 2 are provided with annular every slag chute 4-1.Therefore, when there being impurity in fluid, spheroid 2 rotates and impurity will be brought into annular in slag chute 4-1, and avoid spherome surface to be pulled, fluid can not be revealed.
