Abstract
The utility model discloses a valve gear which is arranged on pipelines, and is used to allow or disallow medium on the pipelines to flow and disallow the medium to flow back. The valve gear comprises components such as a valve body, a sphere, a valve flap, a valve seat, etc. The sphere is rotated, so that the medium in the pipelines can be allowed to flow or not. The valve flap is turned open and is dropped, so that the valve gear has the backflow prevention function of avoiding the backflow of the medium. The sphere is rotated 180 DEG, and the bi-directional backflow prevention is realized. Because one valve has two usages, the utility model has the advantages of wide range of application, less investment and low cost.
Description
The utility model relates to a kind of industrial pipeline valving.
To on pipeline, realize switching and non-return effect at present to flowing medium, at least need be with the valve of two kinds of difference in functionalitys, a kind of is to cut-off valve, as ball valve; Another kind is to end valve.To the medium of one-way flow, above-mentioned valve need respectively be installed one, and then each needs 2 to two-way flow.
The purpose of this utility model is to propose a kind of switching that can control media, just can play again simultaneously, the novel valve (see figure 3) of contrary dual check effect.
Task of the present utility model is achieved in that the closure member of valve is one to be installed in the spheroid 2 in the valve body 1, has a through hole in the spheroid.By valve rod 6 spheroid 2 is rotated in valve body 1, the ball hole communicates with pipeline to opening, and spheroid 2 half-twists are for closing.Valve seat 4 is installed in the ball hole, and flap 3 is articulated in the hole wall, can rotate up and down.When media flow, valve 3 revolves and opens, and medium passes through; When back-pressure, flap falls the non-return effect of having blinded off a line.Make spheroid 2 Rotate 180s °, can play switching and non-return effect the medium of reverse flow.
The utility model is simple in structure, and sealing is reliable, and is applied widely, and operation and maintenance is convenient, not only a valve has the function of two kinds of valves, and can play just contrary dual check effect, uses little investment thereby a valve can push up 2-4 valve, cost is low, and the position that takes up room is few, and comprehensive benefit is good.
1---valve body, 2---spheroid, 3---flap, 4---valve seat, 5---bearing pin, 6---valve rod.
Embodiment:
Spheroid 2 is installed and is sealed in the valve body 1, and pull valve rod 6 spheroid 2 is rotated, be the enable possition to illustrate 0 °, changeing 90 ° is closed position, changeing 180 ° is reverse position.Be embedded with a ring-shaped valve seats 4 on spheroid 2 through holes one end inwall, disc flap 3 upper ends are connected with hole wall by bearing pin 5.Flap 3 rotates around bearing pin 5, upwards for opening, falls to closing.
Claims (1)
- One by valve body 1, the ball that spheroid 2 and valve rod 6 are formed, ends the Two purpose valve device, it is characterized in that spheroid 2 through holes one end is embedded with a round ring seat 4, and the upper end of disc flap 3 links to each other with hole wall by bearing pin 5.
