Description
Technical field
The present invention relates to valve technology field, particularly relate to a kind of ball valve.
Background technique
Ball valve is as a kind of valve, with the compact of its structure and operation quick, conveniently be widely used in oil, chemical industry, generating, papermaking, atomic power, aviation, in the industrial fields such as rocket and daily life, ball valve has generally comprised valve body, valve gap, valve seat, valve ball, valve rod and operating device thereof, but all only have 1 valve ball in the valve body of traditional valve ball, valve ball is as the critical piece of ball valve controls fluid, it is subject to washing away of fluid and corrodes the most serious, once valve ball is by erosion, ball valve is by effect of damming out of hand, unnecessary economy and property loss will be caused, even cause unnecessary security incident, thus, if make the longer service life of ball valve, and the effect with function backup becomes ball valve technician problem demanding prompt solution.
In January, 2010, the notification number of notice of authorization on the 20th was that the utility model patent of CN201386818Y discloses a kind of dual control ball valve; it includes valve body, valve gap, valve seat, valve rod, spool and operating device; described valve gap is fixedly connected with valve body; described valve seat is placed in valve body; described valve rod one end is placed in valve body and is connected with spool, and its other end is connected with operating device; Be provided with two groups of spools in the cavity volume that it is characterized in that described valve body, its two groups of spools are connected with independently valve rod and operating device respectively, and in described valve body, be also provided with two groups of valve seats, two groups of described spools are sealed and matched mutually with corresponding valve seat respectively; The beneficial effects of the utility model are in valve body, arrange two groups of spools, valve rod, valve seat and operating device, adopt this structure, when wherein one group of spool and valve seat occur to leak in valve body, owing to also having being sealed and matched of other one group of spool and valve seat, so can not have an impact to valve, meanwhile, two groups of spools are set, can also rate-of flow in more accurate control valve body.Its deficiency in: 1) volume is large, and consumptive material is many, and cost of production is high; 2) need to operate respectively 2 different operating devices when opening stream and dam, cannot simultaneously operating be realized.
Summary of the invention
The object of this invention is to provide the ball valve that a kind of volume is little, consumptive material is few, cost is low, the life-span is long, simultaneously operating is easy.
The technological scheme adopted for realizing object of the present invention is: a kind of Composite valve ball, comprises and is arranged on outer field outer valve ball, arranges interior valve ball in described outer valve ball, and described interior valve ball is rotatably connected with the axis of outer valve ball along valve rod.
Between described outer valve ball and interior valve ball, rotating seal member is set.
Described valve ball is elliposoidal valve ball.
A kind of ball valve using described Composite valve ball, comprise ball valve body, Composite valve ball and operating device, described Composite valve ball is arranged on ball valve body inside, outer valve ball in described Composite valve ball is connected with described operating device by ectosphere link, and described interior valve ball is connected with described operating device by interior ball link.
Described ectosphere link is hollow outer valve rod, and described interior ball link is arranged on the inner valve stem in described outer valve rod.
Described operating device comprises Composite valve ball synchronous control component and asynchronous controlling component.
Composite valve ball of the present invention, comprise and be arranged on outer field outer valve ball, in described outer valve ball, interior valve ball is set, described interior valve ball is rotatably connected with the axis of outer valve ball along valve rod, outer valve ball in described Composite valve ball is connected with described operating device by ectosphere link, described interior valve ball is connected with described operating device by interior ball link, have effectively achieved that to the invention provides a kind of volume little, consumptive material is few, cost is low, life-span is long, the object of the ball valve that simultaneously operating is easy, compared with the ball valve of traditional two groups of spools is set, not only dramatically saves on valve ball consumables cost, and dramatically saves on the consumables cost of valve body, greatly reduce the volume of ball valve, take more space less, the ball valve of use Composite valve ball of the present invention, can change according to the difference of pressure, optionally use interior valve ball or outer valve ball or use interior valve ball and outer valve ball simultaneously, select variation, during usual use, we can only use interior valve ball to control, or valve ball and outer valve ball control in interval uses, once interior valve ball breaks down, we can operate outer valve ball at once and control, effectively avoid unnecessary economic loss, eliminate and use other ball valves to carry out carrying out safety backup, and effectively the working life of single ball valve is extended to more than 2 times, greatly save cost.By arranging rotating seal member between valve ball and interior valve ball outside, efficiently avoid the generation of fluid from leakage situation between outer valve ball and interior valve ball; By arranging ellipse valve ball, drastically increase high voltage performance and the anti-erosion property of valve ball; By arranging synchronous control component for controlling interior valve ball and outer valve ball and asynchronous controlling component on described operating device, both can with valve ball and outer valve ball in having entered to control, again can valve ball and outer valve ball in synchronization control, operation variation.The present invention is simple and practical, and volume is little, cost is low, and safety coefficient is high, and should be widely promoted application.
