Abstract
The utility model discloses a ball valve, which is characterized in that the utility model comprises two support shut rods and two sealing ball clack components and a four-bar mechanism, and the opening and the closing of the utility model can be accomplished via the ascending, the descending and the rotation movement of a valve rod. The utility model not only has the characteristics of rapid opening and closing, simple structure and small size of common ball valves, but also has the characteristics of high temperature resistant, high voltage resistance, corrosion resistance, small operation moment, etc.
Description
The valve that the utility model relates to a kind of controlling plumbing fixtures medium circulation and blocks, particularly a kind of ball valve.
At present, in the middle of controlling plumbing fixtures medium circulation or the valve that blocks, the structural type of ball valve and performance are superior than other valve, it be have simple in structure, advantage such as switch is rapid.In order further to improve wear-resisting, high temperature resistant, the corrosion resistant performance of sealing surface, some people is the pile-up welding hard alloy material on the sealing surface of valve, plays certain effect.But, owing to also exist easy biting the end of knot between the sealing surface, phenomenon such as pull, and adopt soft materials such as nylon, teflon or rubber to make seal elements, and then having influenced high temperature resistant, high pressure resistant, the decay resistance of valve, using scope is restricted.
The utility model is to reach its purpose of phase by the following technical solutions.
Hold together bar, ball clack and bearing pin comprising by valve body, valve gap, support, handwheel, valve rod, guide finger, support, in the middle of the ball valve that is constituted, valve gap is fixedlyed connected with the valve body upper end; Be equipped with valve rod in the valve gap, also be equipped with guiding groove on this valve rod, make valve rod after the handwheel rotation, do up, descending, half-twist motion.The end that bar is held together in two supports is respectively with the upper end hinge of two ball clacks, and two ball clacks hold together in two supports to do the support disturbance under the effect of bar and do.The two symmetrical ball clacks that have sealing surface are put among valve body, and the bottom of two ball clacks is hinged together.Bar the other end hinge is held together with two supports in the bottom of valve rod.
Characteristics such as the fluid resistance that the utility model had both kept former ball valve is little, and switch is rapid, simple in structure have performances such as high temperature resistant, high pressure resistant, corrosion-resistant again, and have eliminated the biting the end of knot that occurs between the sealing surface, pull phenomenon.The switch moment of product is very little, steady quality, working life are longer.
To further specify structure characteristic of the present utility model based on drawings and Examples below.
Fig. 1 is the utility model structural representation;
Schematic representation when Fig. 2 is a ball clack rounding state of the present utility model;
Schematic representation when Fig. 3 is the utility model full open state;
Referring to Fig. 1, valve rod 3 holds together bar 6 usefulness bearing pins 10 with support and is connected, and two supports are held together bar 6 and are connected with two sealing ball clacks, 7 usefulness bearing pins 10; Fixedly connected with valve gap 5 in the upper end of valve body 8.Be equipped with valve rod 3 in valve gap 5 and the support 2, these valve rod 3 upper ends connect handwheel 1, and this handwheel 1 can take valve rod 3 to, rotate on valve gap 5 and support 2.On this valve rod 3 guiding groove is arranged, guide finger 4 is arranged on the support 2 when valve rod 3 moves up and down, lead during rotation, centering ball 9 works two ball clacks and the centering effect of connecting in the valve body bottom, when needs are opened the utility model, rotation hand wheel 1 in the counterclockwise direction, because guide finger 4 interaction in the guiding groove straight section on valve rod 3 on the support 2, it is up that bar 6 one ends are held together in valve rod 3 drive supports, draw in to the center with the other end of ball clack 7 hinges, drive ball clack 7 simultaneously and leave sealing surface and draw in, go into gap (referring to Fig. 2) between ball clack 7 and valve body 8 sealing surfaces to the center.Handwheel 1 continues rotation, and guide finger 4 guiding groove on valve rod 3 tiltedly interacts in the section, and valve rod 3 rotates, and drives simultaneously to support bar 6 and ball clack 7 rotates, and the runner hole in two ball clacks 7 communicates (referring to Fig. 3) with runner hole on the valve body 8, and valve is all opened.
Otherwise, when the needs throttle down, handwheel 1 turns clockwise, guide finger 4 guiding groove on valve rod 3 tiltedly interacts in the section, valve rod 3 rotates, bar 6 is held together in drive support simultaneously and ball clack 7 rotates, at this moment, ball clack 7 runner holes and valve body 8 runner holes are perpendicular, continue rotation hand wheel 1, guide finger 4 interacts in the guiding groove straight section on valve rod 3, valve rod 3 is descending, and it is descending that bar 6 one ends are held together in the drive support, close to 8 liang of sealing surfaces of valve body with the other end of ball clack 7 hinges, be close to the formation sealing state until ball clack 7 and 8 liang of sealing surfaces of valve body, at this moment the valve Close All.
Technological scheme described in the present embodiment is applicable to ball valve.
