Description

Technical Field

[0001] The utility model relates to the field of angle valves, in particular to pneumatic angle valves. Background Art

[0002] An angle valve is an angle globe valve. The angle valve is similar to a ball valve, and its structure and characteristics are modified from the ball valve. The difference from the ball valve is that the outlet of the angle valve forms a 90-degree right angle with the inlet. The angle valve is also called a three-way valve, an angle valve, or a corner water valve. This is because the pipeline forms a 90-degree corner shape at the angle valve, so it is called an angle valve, an angle valve, or a corner water valve. The existing angle valve has a relatively complex structure and a large volume, which is more troublesome in the actual installation and debugging process. At the same time, the angle valve of the existing technology rotates the handle manually to drive the plugging member away from or close to the water inlet to realize the opening and closing of the water inlet of the valve body. Therefore, a pneumatic angle valve is proposed. Content of the Utility Model

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present utility model.

[0016] Please refer to Figure 1-2 In the embodiment of the present utility model, a pneumatic angle valve includes a valve body 1. A cylinder block 2 is vertically arranged at the top end of the valve body 1, and the cylinder block 2 is in mutual communication with the valve body 1. A piston guide rod 5 is vertically arranged on one side inside the cylinder block 2, and a piston 6 is horizontally arranged on the side of the piston guide rod 5. The piston 6 is horizontally located inside the cylinder block 2, and the piston 6 moves up and down on the side of the piston guide rod 5. A piston rod 10 is vertically arranged at the bottom end of the piston 6, and the piston rod 10 penetrates through the cylinder block 2 and is vertically located inside the valve body 1, and the piston rod 10 and the piston 6 are in the same movement direction. A valve plate 11 is horizontally arranged at the bottom end of the piston rod 10, and the valve plate 11 is horizontally located at the bottom end inside the valve body 1, and the valve plate 11 and the piston rod 10 are in the same movement direction. Thus, when the piston 6 moves up and down inside the cylinder block 2, it drives the piston rod 10 to drive the piston 6 to move up and down inside the valve body 1, so as to open or close the valve body 1. And when the piston 6 moves up and down inside the cylinder block 2 through the piston guide rod 5, it is more stable and effectively extends the service life of the piston 6. Further, when the piston rod 10 drives the valve plate 2 to lift inside the valve body 1, it is more stable.

[0017] The cylinder block 2 is provided with a first mechanical sensor 3, and the first mechanical sensor 3 is located at one side of the outer top end of the cylinder block 2. A second air port 8 is arranged at one side of the outer bottom end of the cylinder block 2, and the second air port 8 is piped to the cylinder block 2. The second air port 8 is piped and connected to an external inflation device, and the first mechanical sensor 3 is electrically connected to the external inflation device. Thus, the external inflation device inflates the inside bottom end of the cylinder block 2 through the second air port 8, so as to lift the piston 6 located at the bottom end of the cylinder block 2 and when the piston 6 is lifted to the top end inside the cylinder block 2, the first mechanical sensor 3 senses the piston 6 and controls the external inflation device to stop air intake. Thus, the piston 6 contacts with the top end of the cylinder block 2, so as to drive the piston rod 10 to drive the valve plate 12 to rise inside the valve body 1.

[0018] A second mechanical sensor 4 is provided between the valve body 1 and the cylinder block 2, and the second mechanical sensor 4 is located at one side of the outer top end of the valve body 1. A first air port 7 is provided at one side of the outer top end of the cylinder block 2, and the first air port 7 is connected to the cylinder block 2 through a pipeline. The first air port 7 is also connected to an external inflation device through a pipeline. The second mechanical sensor 4 is electrically connected to the external inflation device. Thus, the external inflation device inflates the inner top end of the cylinder block 2 through the first air port 7, and when the piston 6 located at the top end of the cylinder block 2 is pressurized and pressed to the inner bottom end of the cylinder block 2, the second mechanical sensor 4 senses the piston 6 and controls the external inflation device to stop intake. Then, the piston 6 contacts the bottom end of the cylinder block 2, driving the piston rod 10 and the valve plate 12 to descend inside the valve body 1 to block the valve 1.

[0019] A cylinder base 9 is further provided between the valve body 1 and the cylinder block 2. The cylinder base 9 is horizontally located at the top end of the valve body 1, and the cylinder block 2 is vertically located at the bottom end of the cylinder base 9. The piston rod 10 penetrates through the cylinder base 9, and the piston rod 10 moves up and down at the middle position of the cylinder base 9.

[0020] The valve body 1 is formed with an eight-shaped port 12. The eight-shaped port 12 is horizontally located at the side of the outer bottom end of the valve body 1 and penetrates through the valve body 1. Thus, the flow rate of the fluid flowing into or out of the valve body 1 is faster through the eight-shaped port 12.

[0021] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model.
