Abstract
The utility model discloses a square hole ball valve. A valve body of the square hole ball valve has a hollow cylinder structure; a ball is arranged in the valve body; the ball is provided with a square hole flow channel; a valve seat 4a and a valve seat 4b are arranged between two ends of the ball and the valve body; a disc spring is arranged between the valve seat 4a and the valve body; the middles of the valve seat 4a and the valve seat 4b are provided with valve seat square hole flow channels; the valve seat square hole flow channels are matched with the square hole flow channel of the ball; the upper part of the ball is embedded with a valve rod; one end of the valve rod penetrates the valve body; the ball can rotate 90 DEG in the valve body by taking the valve rod as an axis in order to open and close a valve body passage; and the ball can be driven to rotate when the valve rod is rotated, a rectangular flow channel port is formed between the square hole flow channel and the valve seat square hole flow channels, and an area of the rectangular flow channel port is in a linear relationship with a rotating angle of the ball. In the square hole ball valve, a flow and an opening degree of the valve are in a linear relationship in the opening and closing processes, so the square hole ball valve is applicable to precise linear adjustment, and the application range is expanded.
Description
Technical field
The utility model relates to a kind of square hole ball valve.
Background technique
Existing ball valve generally comprises valve body, valve rod, spheroid, spring, valve seat, and spheroid and valve seat have circular hole and flow to.Valve rod and spheroid mechanical bond, seal element are spheroid and valve seat, and spheroid becomes sphere to cooperate with valve seat, spheroid is that rotating shaft can be done 90 degree rotations with the valve rod in valve body, to open and close valve body (pipeline) passage, stop channel media to flow, the elastic force of spring is close to spheroid and valve seat.The deficiency of existing this ball valve is, when valve is opening or closing little aperture in the process, spheroid and valve seat cooperate the oval mouthful runner of formation, area is little, negotiability is also little, and flow velocity increases, and the ball mouth of spheroid and the valve seat mouth of valve seat are washed away by flowing medium easily, and valve can not be done the precise characteristics adjusting by convection cell.
The model utility content
The purpose that the utility model relates to provide a kind of when overcoming the little aperture of existing product in the process of opening or closing the valve seat mouth of the ball mouth of spheroid and valve seat easily dash the square hole ball valve of the deficiency of decreasing, can't accurate flow adjustment.
The technical solution of the utility model is: a kind of square hole ball valve, and it comprises valve rod, valve body, spheroid, valve seat 4a, valve seat 4b, dish spring, and described valve body is the hollow cylinder structure, is provided with spheroid in the valve body, and described spheroid is provided with the square hole runner; Be respectively equipped with valve seat 4a and valve seat 4b between described spheroid and the valve body two ends, be provided with the dish spring between valve seat 4a and the valve body, described valve seat 4a and valve seat 4b middle part are provided with valve seat square hole runner, and valve seat square hole runner cooperates with the square hole runner of spheroid; Described spheroid top is embedded with valve rod, one end of valve rod passes from valve body, spheroid can valve rod be that axle 90 degree in valve body rotate to open and close valve channel, can drive spheroid during rotation valve rod rotates, form rectangular runner mouth this moment between square hole runner and the valve seat square hole runner, and the area of rectangular runner mouth and spheroid rotation angle are linear.
The beneficial effects of the utility model are: when the valve open or the little aperture of closing, spheroid cooperates the rectangular runner degree of lip-rounding that forms with valve seat, the oval open area that forms during the little aperture of existing relatively ball valve increases greatly, thereby increased negotiability, reduced flow velocity, reduced the dash damage of fluid, increased the service life ball mouth and valve seat mouth; Spheroid cooperates the rectangular runner open area that forms to become linear dependence with the aperture of valve with valve seat, thereby the flow of valve and aperture are also linear, make valve have the linear performance regulatory function; Its using scope is wider: carry applicable to solid powder, slurry conveying etc. are to spheroid and the serious medium of the prooving of valve seat, and fluid needs the system pipeline of operating modes such as accurately adjusting.

Fig. 1 is the sectional drawing of the described square hole ball valve of the utility model embodiment.
Fig. 2 is an A-A view among Fig. 1.
The structural representation of the rectangular runner mouth that Fig. 3 forms when being the little aperture of the described square hole ball valve of the utility model embodiment.
Embodiment
Embodiment as Figure 1-3, a kind of square hole ball valve comprises valve rod 1, valve body 2, spheroid 3, valve seat 4a, valve seat 4b, dish spring 5, described valve body 2 is the hollow cylinder structure, is provided with spheroid 3 in the valve body 2, described spheroid 3 is provided with square hole runner 6; Be respectively equipped with valve seat 4a and valve seat 4b between described spheroid 3 and valve body 2 two ends, be provided with dish spring 5 between valve seat 4a and the valve body 2, dish spring 5 can make spheroid 3 and valve seat 4a and valve seat 4b be close to and form sealing configuration, described valve seat 4a (4b) middle part is provided with valve seat square hole runner 7, and valve seat square hole runner 7 cooperates with the square hole runner 6 of spheroid 3; Described spheroid 3 tops are embedded with valve rod 1, and valve rod 1～end passes from valve body 2, and spheroid 3 can valve rod 1 be that axle 90 degree in valve body 2 rotate to open and close valve body (pipeline) passage.Can drive spheroid 3 during rotation valve rod 1 rotates, form rectangular runner mouth 8 this moment between square hole runner 6 and the valve seat square hole runner 7, and the area of rectangular runner mouth 8 and spheroid 3 rotation angles are linear, can control the size of rectangular runner mouth 8 by regulating valve stem 1 rotation angle, and then the flow and the flow velocity of control valve body (pipeline) inner fluid passage.
