Further, be fixed with the bulge loop that cooperates with upper channel on the said valve ball.
Further, the corresponding lower channel of said valve body lower end and upper channel, said valve ball lower end is fixed with the bulge loop that matches with said lower channel.
Further, said valve ball all is fixed with bulge loop in two ends up and down, and said bulge loop matches with upper channel, lower channel respectively.
Further, said bulge loop and valve ball integrative-structure.
Further, said valve body is provided with the joint that is connected with left passage, right passage, between said joint and valve seat, is provided with the dish spring.
Further, said valve rod has baffle ring.
Further, said operating device lower end is provided with draw-in groove, and said valve body upper end is fixed with said draw-in groove and constitutes the circumferential spacing limited post that cooperates.
Further, said valve body upper channel is provided with step.
Compared with prior art; The utlity model has following beneficial effect: valve ball adopts gudgeon type ball; Packing into greatly reduces the swing of valve ball in valve body behind the valve body chamber, has improved the positional accuracy of valve ball in valve body, the gap of having reduced ball and body cavity; Reduced the wearing and tearing between spheroid and valve body, reduced the operation moment of torsion simultaneously and prevented to go out because of reasons such as pressure make ball.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure, valve body 1, valve ball 2, valve rod 3, operating device 4, valve seat 5, upper channel 6, bulge loop 7, lower channel 8, joint 9, dish spring 10, baffle ring 11, draw-in groove 12, limited post 13, step 14, Sealing 15.
Embodiment
Be described further to the embodiment of accompanying drawing below the utility model:
Shown in figure; A kind of on-line automatic compensation sealing high-pressure ball valve; Comprise valve body 1, valve ball 2, valve rod 3, operating device 4 and valve seat 5, said valve rod 3 penetrates the upper channel 6 of valve body 1 and is connected with valve body 1 interior valve ball 2, and said valve seat 5 matches with valve ball 2; Said operating device 4 is connected with valve rod 3, and said valve ball 2 upper and lower at least one ends are fixed with valve body 1 and constitute the radially spacing bulge loop that cooperates 7.According to such scheme; Valve ball adopts gudgeon type ball; Packing into greatly reduces the swing of valve ball 2 in valve body 1 behind valve body 1 chamber, has improved the positional accuracy of valve ball 2 in valve body 1, has reduced the gap of valve ball 2 with valve body 1 inner chamber; Reduced the wearing and tearing of 1 of valve ball 2 and valve body, reduced the operation moment of torsion simultaneously and prevented to go out because of reasons such as pressure make ball.
In the utility model, said valve ball 2 upper ends are set are fixed with the bulge loop 7 that cooperates with upper channel 6.Said valve body 1 lower end is provided with and upper channel 6 corresponding lower channels 8, and said valve ball 2 lower ends are fixed with the bulge loop 7 that matches with said lower channel 8.Preferably be employed in said valve ball and all be fixed with bulge loop 7 in two ends about in the of 2, said bulge loop 7 matches with upper channel 6, lower channel 8 respectively, can guarantee effectively that like this valve ball reaches optimum efficiency.
In the utility model, said bulge loop 7 and valve ball 2 integrative-structures.Adopt the favourable raising intensity and the stability of integral type.
In the utility model, said valve body 1 is provided with the joint 9 that is connected with left passage, right passage, between said joint 9 and valve seat 5, is provided with dish spring 10.Dish spring 10 loads valve seat 5, can make 5 pairs of valve balls of valve seat 2 produce rational sealing load, reduces frictional force, can not produce excessive moulding pressure, has reduced the operation moment of torsion, makes ball valve lighter when open and close, and feel is better.When the online use of high and low pressure, have automatic compensation drip-preventing function, reduced the prooving of valve seat that causes because of reasons such as pressure jumps and produced leakage.
