Abstract
The utility model relates to a square hole ball valve which comprises a valve rod, a valve body, a sphere, two valve seats and disc springs; the valve body is provided with the sphere; a square hole flow passage is arranged on the sphere; the two valve seats are respectively arranged between two ends of the sphere and the valve body; the disc springs are arranged between the valve seats and the valve body; the middle of the valve seat is provided with a square hole flow passage of the valve seat which is matched with the square hole flow passage of the sphere; the valve rod is embedded into the upper part of the sphere; one end of the valve rod runs through the valve body; and the sphere can rotates at 90 degrees in the valve body by using the valve rod as a shaft. The square hole ball valve has the advantages that when the valve is opened or closed at a small degree, the sphere and the valve seats are matched to form a rectangular flow passage port so as to enlarge the circulating area of a fluid; in the opening and closing process, the flow rate and the opening degree of the valve form a linear relation which can be used for accurate and linear adjustment; and the square hole ball valve is suitable for a system pipeline for transporting solid powdery materials, slurry, and the like and for carrying out accurate adjustment to a medium and a fluid which seriously damage the valve body and other working conditions, and enlarges the application range.
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 provides a kind of square hole ball valve, and the valve seat mouth of the ball mouth of spheroid and valve seat easily dashes the deficiency of decreasing, can't accurate flow adjustment when overcoming the little aperture of existing product in the process of opening or closing.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of square hole ball valve comprises valve rod, valve body, spheroid, two valve seats, dish spring, is provided with spheroid in the described valve body, and described spheroid is provided with the square hole runner; Be respectively equipped with valve seat between described spheroid and the valve body two ends, be provided with the dish spring between described valve seat and the valve body, described dish spring can make spheroid and valve seat be close to and form sealing configuration, and described valve seat middle part is provided with valve seat square hole runner, and described valve seat square hole runner cooperates with the square hole runner of spheroid; Described spheroid top is embedded with valve rod, and valve rod one end passes from valve body, and spheroid can valve rod be that axle 90 degree in valve body rotate, to open and close valve body (pipeline) passage.
The beneficial effect of square hole ball valve described in the utility model is: 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.
Description of drawings
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.
Among the figure: 1, valve rod; 2, valve body; 3, spheroid; 4a, valve seat; 4b, valve seat; 5, dish spring; 6, square hole runner; 7, valve seat square hole runner; 8, rectangular runner mouth.
Embodiment
As Figure 1-3, the described square hole ball valve of the utility model embodiment comprises valve rod 1, valve body 2, spheroid 3, valve seat 4a, valve seat 4b, dish spring 5, and described valve body 2 is the hollow cylinder structure, is provided with spheroid 3 in the valve body 2, and 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 one ends pass 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.
