Description
Technical field
The utility model relates to the ball valve technical field, particularly a kind of trisome formula fixing ball valve.
Background technique
In water-feeding ﹠ drainaging pipeline, the main effect of fixing ball valve is to cut off, distribute and change the flow direction of medium.Traditional fixing ball valve passes through fixedly spheroid of upper and lower valve rod usually, and this structure setting requires the quality of fit height of each parts, the processing and fabricating difficulty, and required each number of fitting parts of valve is more, has increased the cost of production expense of fixing ball valve.In addition, in long-term using process, cause easily because of friction between the lower valve rod of valve and the spheroid increases to cause to cooperate spacing to increase, thereby the displacement of generation spheroid is unfavorable for the sealing of fixing ball valve, influences whole tubing.In addition, usually adopt O shape cushion rubber and use mode, come the zero leakage of real valve in traditional fixing ball valve top seal structure, but frequent when fixing ball valve keying number of times, cause the damage of O shape cushion rubber easily, influence sealing effect.So in order to overcome the defective of said fixing spherical ball valve, it is very necessary that valve is carried out architecture advances.
The model utility content
The purpose of this utility model is at the deficiencies in the prior art, provides a kind of reasonable in design, good sealing effect and fabricating cost low trisome formula fixing ball valve.
For achieving the above object, the utility model is by the following technical solutions:
The utility model trisome formula fixing ball valve comprises left valve barrel, middle valve body, right valve barrel, spool and start-stop device; The left and right sides of valve body during described left valve barrel and right valve barrel are fixed at respectively; In the valve body, described start-stop device was located at middle valve body top during described spool was located at; Described spool is made up of upper valve rod and spheroid, and spheroid top is fixed in described upper valve rod bottom; Body cavity top is fixed with the filler cover in described, and described filler cover top is provided with pressing plate; The upper valve rod upper end is passed the filler cover and is connected with the output shaft of start-stop device; The exterior edge face of described left valve barrel and right valve barrel is provided with flange.
Further, described upper valve rod lower cross section is oblate, is arranged in the mounting groove on spheroid top, and the size shape of the size shape of described mounting groove and upper valve rod bottom is complementary.
Wherein, described start-stop device comprises worm gearing and the rotating disc that is connected with worm gearing, and described upper valve rod is connected with the output shaft of worm gearing.
Further, described spheroid bottom is provided with spacer.
Described spacer is fixed on left valve barrel and the right valve barrel by straight pin.
