Description

Technical Field

[0001] The utility model relates to the technical field of ball valves, in particular to a right-angle movable ball valve. Background Art

[0002] A ball valve's opening and closing element (the ball) is driven by the valve stem and rotates around its axis. It can also be used for fluid regulation and control. The hard-sealed V-shaped ball valve, with its V-shaped core and carbide-clad metal seat, creates a strong shear force, making it particularly suitable for media containing fibers and tiny solid particles. Multi-way ball valves, on the other hand, not only flexibly control the confluence, diversion, and direction of flow in pipelines, but can also close any channel while connecting the other two.

[0003] In existing technology, the inlet and outlet structures of common straight-through ball valves are straight connections, which are not suitable for vertical pipe installation. The addition of a 90-degree elbow during installation increases the difficulty of surrounding layout. Furthermore, the direct installation between the valve and the main pipe makes it difficult to choose a suitable position based on the surrounding space, resulting in a small space around the installed valve, making it difficult to access the valve stem when the valve needs to be adjusted later. Inventing a right-angle flexible ball valve to solve these problems has become a pressing issue for those skilled in the art. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a right-angle flexible ball valve, which aims to solve the problem that the space around the common valve is small and it is difficult to contact the valve stem when the valve is directly installed between the main pipe.

[0005] The utility model is achieved in this way:

[0006] The utility model provides a right-angle flexible ball valve, comprising a valve body, a fixed pipe and a quick-connect joint arranged on the valve body, wherein the two inlets and outlets of the valve body are arranged vertically;

[0007] The two fixed tubes are welded to the inlet and outlet of the valve body. A slot is provided on the inner side wall of the fixed tube. A plurality of spherical grooves are provided on the inner wall of the slot. Balls are installed on the inner wall of the spherical groove. A fixed ring is installed on the outer side wall of the fixed tube. A spring is provided on the outer wall of the fixed ring. An adjustment sleeve is installed on the side wall of one end of the spring. An oblique groove is provided on the inner wall of the adjustment sleeve.

[0008] One end of the quick-insert connector is plugged into the inner wall of the slot, and a plurality of positioning grooves are provided on the side wall of the quick-insert connector.

[0009] Preferably, the two fixed tubes are welded to the side wall of the valve body, a sealing gasket is installed on the inner wall of the spherical groove, and the outer wall of the ball and the inner wall of the spherical groove are movably connected.

[0010] Preferably, the fixing ring and the fixing tube are designed as one body, and the side walls at both ends of the spring are fixedly connected to the fixing ring and one end of the adjusting sleeve respectively.

[0011] Preferably, the inner wall of the adjusting sleeve is slidably connected to the outer wall of the fixing tube, and the side wall of the inclined groove is slidably connected to the side wall of the ball.

[0012] Preferably, a sealing ring is installed on the inner wall of the slot and abuts against one end of the quick-plug connector, and the inner wall of the positioning groove is clamped with the ball bearing.

[0013] By adopting the above technical solution, the vertically arranged inlet and outlet will convert the straight connection of the valve body into a vertical connection. When installing the vertical pipeline, the right-angle elbow can be discarded to change the direction of the interface, reducing the installation cost. The quick-plug connector can be quickly installed on the appropriate inlet and outlet pipes according to needs, solving the problem of unreasonable installation of vertical pipelines, changing the spatial position between the main pipe and the valve body, and adjusting the valve stem position of the valve body, so that the valve stem can be accessed later to adjust the valve.

[0014] Preferably, an adjusting ring is threadedly connected to the outer wall of the fixing tube, and a positioning ring threadedly connected to the outer wall of the adjusting sleeve is installed on one side of the adjusting ring.

[0015] By adopting the above technical solution, the provided positioning ring can enhance the fixing strength of the quick-insert connector, thereby preventing the adjustment sleeve from loosening due to vibration, thereby preventing the quick-insert connector connection from loosening and causing leakage.

[0016] The beneficial effects of the utility model are:

[0017] The vertically arranged inlet and outlet converts the straight connection of the valve body into a vertical connection. When installing vertical pipes, the right-angle elbow can be discarded to change the direction of the interface, reducing the installation cost. The set quick-plug connector can be quickly installed in the appropriate inlet and outlet pipes according to needs, solving the problem of unreasonable installation of vertical pipes, changing the spatial position between the main pipe and the valve body, and adjusting the valve stem position of the valve body, so that the valve stem can be accessed later for adjustment of the valve.

[0027] One end of the quick-insert connector 6 is plugged into the inner wall of the slot 21 , and a plurality of positioning grooves 61 are formed on the side wall of the quick-insert connector 6 .

[0028] Furthermore, the two fixed tubes 2 are welded to the side walls of the valve body 1, the inner wall of the spherical groove 22 is installed with a sealing gasket, the outer wall of the ball 42 is movably connected to the inner wall of the spherical groove 22, the fixing ring 23 and the fixed tube 2 are designed as an integral whole, the side walls at both ends of the spring 3 are fixedly connected to the fixing ring 23 and one end of the adjusting sleeve 4, the inner wall of the adjusting sleeve 4 is slidingly connected to the outer wall of the fixed tube 2, the side wall of the inclined groove 41 is slidingly connected to the side wall of the ball 42, the inner wall of the slot 21 is installed with a sealing ring 7 that abuts one end of the quick-plug connector 6, and the inner wall of the positioning groove 61 is clamped to the ball 42.

[0029] It should be noted that the vertically arranged water inlet and outlet converts the straight connection of the valve body 1 into a vertical connection. When installing a vertical pipe, the right-angle elbow can be discarded to change the direction of the interface, thereby reducing the cost of installation. The inner wall of the pipe joint is also provided with a positioning groove 61 that is the same as the inner wall of the quick-plug connector 6. The pipes on the water inlet and outlet on both sides of the valve body 1 are installed with the quick-plug connector 6 and the pipe joint respectively.
