Abstract
The utility model provides a novel ball check valve, it includes valve body (7), the inner wall shrink department at valve body right part is provided with disk seat (10), spherical valve clack (6) can disk seat contact, characterized by, install sleeve (3) in the tang of valve body left portion inner wall in the internal diameter of inner wall (4) slightly more than the valve clack, be connected with two strip shaped plates (5) on telescopic right-hand member face symmetrically, open along the axial on the right part of strip shaped plate has guide way (9), it has pivot (8) to run through in the valve clack, insert in the guide way at the both ends of pivot, tang and disk seat coaxial line. The valve seat has the advantages that the rotating shaft of the valve clack is inserted into the guide groove of the strip-shaped plate during assembly, and then the sleeve is pressed into the spigot of the valve seat, so that the valve seat is convenient to assemble; the guide groove has a guide effect on the valve clack, so that the valve clack and the valve seat are positioned on the same axis, and the fluid resistance can be reduced.
Description
Technical Field
The present utility model relates to a check valve for preventing reverse flow of fluid in a pipe.
Background
The ball check valve is used for preventing the fluid in the pipeline from flowing reversely and structurally comprises a valve body, a valve seat and a ball valve clack, when the fluid flows positively, the valve clack is separated from the valve seat by the positive pressure of the fluid, and the valve is opened; when the fluid flows in the reverse direction, the reverse pressure of the fluid causes the valve flap to abut the valve seat, and the valve is closed. The valve has the defects that the valve clack and the valve seat are difficult to center during assembly, and the maintenance is inconvenient.
Disclosure of Invention
Aiming at the defects of the prior art, the utility model provides a novel ball check valve which is convenient to assemble and maintain.
The technical scheme of the utility model is that the novel ball check valve comprises a valve body, a valve seat is arranged at the contraction part of the inner wall of the right part of the valve body, a ball valve clack can be in contact with the valve seat, the inner diameter of the inner wall of the left part of the valve body is slightly larger than the diameter of the valve clack, a sleeve is arranged in a spigot of the inner wall of the left part of the valve body, two strip-shaped plates are symmetrically connected to the right end face of the sleeve, a guide groove is axially formed in the right part of each strip-shaped plate, a rotating shaft penetrates through the valve clack, two ends of the rotating shaft are inserted into the guide groove, and the spigot is coaxial with the valve seat.
The utility model is characterized in that the rotating shaft of the valve clack is inserted into the guide groove of the strip-shaped plate during assembly, and then the sleeve is pressed into the spigot of the valve seat, thus the assembly can be completed; the guide groove has a guide effect on the valve clack, so that the valve clack and the valve seat are positioned on the same axis, and the fluid resistance can be reduced.
Drawings
Fig. 1 is a schematic structural view of the present utility model.
The reference numerals respectively denote: 1-matched flange, 2-left flange, 3-sleeve, 4-inner wall of valve seat left portion, 5-strip shaped plate, 6-valve clack, 7-valve body, 8-pivot, 9-guide slot, 10-valve seat, 11-right flange.
Detailed Description
Specific embodiments of the present utility model will now be described with reference to the accompanying drawings.
The utility model provides a novel ball check valve, it includes valve body 7, the left end of valve body extends there is left flange 2, the right-hand member of valve body extends there is right flange 11, the inner wall shrink department on valve body right part is provided with disk seat 10, spherical valve clack 6 can contact with the disk seat, characterized by, the internal diameter of the inner wall 4 of valve body left part slightly is greater than the diameter of valve clack, install sleeve 3 in the tang of valve body left part inner wall, the length of tang slightly is greater than telescopic length, the sleeve crimping is in the tang, symmetrically be connected with two strip-shaped plates 5 on the telescopic right-hand member face, open along the axial at the right part of strip-shaped plate has guide slot 9, run through in the valve clack has pivot 8, insert in the guide slot at the both ends of pivot, tang and disk seat coaxial line.
The guide groove has a guide effect on the valve clack, so that the valve clack and the valve seat are positioned on the same axis, when fluid flows positively (flows from right to left), the valve clack rolls leftwards away from the valve seat under the positive pressure of the fluid, and when the rotating shaft contacts with the bottom of the guide groove, the opening of the valve is maximum; when fluid flows in reverse (left to right), the reverse fluid pressure causes the valve flap to roll to the right, making contact with the valve seat, and the valve opens and closes.
In order to prevent the sleeve from falling off from the spigot, the left side of the left flange is connected with a matched flange 1, and the inner diameter of the matched flange is equal to the inner diameter of the sleeve. When in use, the matched flange is welded with the pipeline, and then the matched flange is connected with the left flange.
Claims (2)
1. The utility model provides a novel ball check valve, it includes valve body (7), the inner wall shrink department at valve body right part is provided with disk seat (10), spherical valve clack (6) can disk seat contact, characterized by, install sleeve (3) in the tang of valve body left portion inner wall in the internal diameter of inner wall (4) slightly more than the valve clack, be connected with two strip shaped plates (5) on telescopic right-hand member face symmetrically, open along the axial on the right part of strip shaped plate has guide way (9), it has pivot (8) to run through in the valve clack, insert in the guide way at the both ends of pivot, tang and disk seat coaxial line.
2. The novel ball check valve according to claim 1, wherein the left side of the left flange is connected with a mating flange (1), and the inner diameter of the mating flange is equal to the inner diameter of the sleeve.
