Embodiment
With the following Examples the utility model is further described:
A kind of ball valve of the present utility model, as depicted in figs. 1 and 2, comprise valve body 10, spherical spool 20, be arranged at the flange 30, handle 40 at two ends, valve body 10 left and right sides and be connected with handle 40 and control the valve rod 50 that spool 20 rotates, be provided with path 11 that runs through two ends, valve body 10 left and right sides and the through hole 12 that is communicated with path 11 in the valve body 10, spool 20 is arranged in the path 11, valve rod 50 passes through hole 12 and is connected with spool 20, and spherical spool 20 has cross section and is circular passage 21.Ball valve also is provided with cock 100, to compress spherical spool 20, spool 20 is fixed in the block channels 11.During handle with sleeve 40, handle 40 drives connected valve rod 50 and rotates, and the axle that the valve rod 50 drive spools 20 of rotation wind perpendicular to passage 21 rotates, thus the switching and the aperture of control ball valve.Promptly when path 11 was communicated with passage 21, ball valve was opened; When path 11 is not communicated with passage 21, the ball valve closure; Can pass through the aperture of the positioning control ball valve of rotational valve core 20 in addition.Valve body 10 is provided with floor 60 with flange 30 joints.Preferably, floor 60 1 ends are connected with valve body 10, and its other end is connected with flange 30.
Because valve body 10 is provided with floor 60 with flange 30 joints, wherein, floor 60 1 ends can be connected with valve body 10, and the other end can be connected with flange 30, and valve body 10, flange 30 are connected back triangularity structure with floor 60, and it is simple in structure.According to leg-of-mutton geometrical property, triangular support can increase the mechanical strength of valve body 10 and flange 30 joints, thus when ball valve when high temperature and high pressure environment uses, flange 30 is not easy to be out of shape with valve body 10 joints, thereby has prolonged the working life of ball valve.Another preferably, valve body 10 can be provided with corner block 60 with flange 30 joints, the both sides of corner block 60 are connected with flange 30 with valve body 10 respectively, thereby increase the mechanical strength of valve body 10 and flange 30 joints.In like manner, this place's increase valve body 10 also can adopt other structures of prior art to realize with the device of the intensity of flange 30 joints.
As shown in Figure 3, preferably, flange 30 bottoms are provided with support platform 31.Because ball valve flange 30 bottoms are circular, flange 30 bottoms are provided with the area of contact that support platform 31 can increase ball valve and bottom surface or supporter, make ball valve place more steadily, firm, and in the ball valve using process, can not rock because of the force unbalance that is subjected on flange 30 bottoms and ground, thereby guaranteed the normal operation of ball valve, improved the performance of ball valve.
As shown in Figure 1, preferably, spool 20 is provided with first seal ring 70 with valve body 10 passages 21 joints, is provided with second seal ring 71 between valve rod 50 and valve body 10 through holes 12 inwalls.First seal ring 70 can make and be connected closelyr between spool 20 and the valve body 10, avoid joint owing to valve body 10 and spool 20 to be connected to such an extent that the phenomenon of leaking medium appears in defective tightness, and can prevent that extraneous liquid from infiltrating in the ball valve, optimized the performance of ball valve.Equally, second seal ring 71 can make and be connected closelyr between valve body 10 and the valve rod 50, avoid owing to valve body 10 is connected to such an extent that the phenomenon of leaking medium appears in defective tightness with the joint of valve rod 50, and can prevent that extraneous liquid from infiltrating in the ball valve, further improved the performance of ball valve.
As shown in Figure 1, second seal ring, 71 tops are provided with the positioning ring 90 that is placed in valve rod 50 outsides, and positioning ring 90 arranged outside have boss 91, and ball valve also is provided with tubular clamping cap 80, and clamping cap 80 tops are provided with the flange 81 that cooperates with boss 91.During installation, flange 81 is positioned on the boss 91, and clamping cap 80 is placed in valve body 10 through holes 12 outsides.Wherein, positioning ring 90 plays second seal ring, 71 effects that compress; Clamping cap 80 then plays and compresses the positioning ring 90 and second seal ring 71, prevent the effect of leaking.
Preferably, as shown in Figure 2, valve body 10 can be formed in one, and can simplify the structure and the processing technology of valve body 10, reduces the workload of assembling ball valve, and avoids ball valve the phenomenon of water clock to occur, thereby can improve the overall performance of ball valve.
Should be noted that at last; above embodiment is only in order to the explanation the technical solution of the utility model; but not to the restriction of the utility model protection domain; although the utility model has been done to explain with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can make amendment or be equal to replacement the technical solution of the utility model, and not break away from the essence and the scope of technical solutions of the utility model.
