Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a valve which can be opened automatically. Background Art

[0002] Valves are pipe accessories used to open and close pipes, control flow direction, and adjust and control the parameters of the conveyed medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid conveying systems and have functions such as shut-off, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion, or overflow pressure relief.

[0003] Valves are required on the pipelines of some large equipment to control the liquid in the pipes, and the pipeline valves are generally controlled by turning a dial to open and close the valves. However, due to the large size of large equipment, it is inconvenient for personnel to climb up the device to adjust the valves, and personnel cannot operate the valves accurately. In addition, large equipment is surrounded by a high-pressure environment, and accidents are prone to occur when personnel operate the valves, reducing the safety of personnel operations. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art that the equipment is large in size, it is inconvenient for personnel to climb up the device to adjust the valve, and the valve cannot be accurately operated, accidents are prone to occur, and the safety of personnel operation is reduced, and a valve that can be opened automatically is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A valve that can be opened automatically is designed, comprising a valve body, the upper end of the valve body is fixedly connected to a shell, a valve stem for controlling the opening of the valve body is rotatably connected to the shell, a sealing ring is provided between the shell and the valve stem, the upper end of the valve body is fixedly connected to a fixing frame, the upper end of the fixing frame is fixedly connected to a servo motor, the output end of the servo motor is fixedly connected to the valve stem, a rotating block is fixedly connected to the valve stem, and a limit frame for limiting the rotating block is connected to the fixing frame.

[0007] Preferably, the valve body and the housing are an integral structure.

[0008] Preferably, an anti-corrosion layer is sprayed on the fixing frame.

[0009] Preferably, the sealing ring is a corrosion-resistant rubber sealing ring.

[0010] The utility model provides a valve that can be opened automatically, and the beneficial effects are:

[0011] The output end of the servo motor drives the valve stem to rotate a set number of circles clockwise. After the valve stem rotates a set number of circles, it drives the valve core to rotate, thereby opening the valve. The servo motor drives the valve stem to rotate a set number of circles to control the opening and closing of the valve. There is no need to manually rotate the valve stem, which improves the accuracy of valve operation and does not require climbing onto the equipment to operate, which improves the safety of operation and is less likely to cause accidents.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Example 1: Reference Figure 1-5 A valve that can be opened automatically comprises a valve body 1, the upper end of the valve body 1 is fixedly connected with a shell 2, the valve body 1 and the shell 2 are an integral structure, a valve stem 3 for controlling the opening of the valve body 1 is rotatably connected to the shell 2, a sealing ring 4 is provided between the shell 2 and the valve stem 3, the sealing ring 4 is a corrosion-resistant rubber sealing ring, a fixing frame 5 is fixedly connected to the upper end of the valve body 1, an anti-corrosion layer is sprayed on the fixing frame 5, a servo motor 6 is fixedly connected to the upper end of the fixing frame 5, the output end of the servo motor 6 is fixedly connected to the valve stem 3, a rotating block 7 is fixedly connected to the valve stem 3, and a limit frame 8 for limiting the rotating block 7 is connected to the fixing frame 5.

[0020] Working process:

[0021] Initially, the valve body 1 is in a closed state. When the valve needs to be opened, the output end of the servo motor 6 drives the valve stem 3 to rotate a set number of circles clockwise. After the valve stem 3 rotates a set number of circles, it drives the valve core to rotate, thereby opening the valve. At the same time, the valve stem 3 drives the rotating block 7 to rotate. After the rotating block 7 rotates a set number of circles, it is inserted into the limiting frame 8. The limiting frame 8 limits the rotating block 7, thereby limiting the valve stem 3.

[0022] When it is necessary to close the valve, the output end of the servo motor 6 drives the valve stem 3 to rotate the set number of circles counterclockwise to reset. After the valve stem 3 rotates the set number of circles, it drives the valve core to rotate, thereby closing the valve. At the same time, the valve stem 3 drives the rotating block 7 to rotate, so that the rotating block 7 is separated from the limit frame 8. The servo motor 6 drives the valve stem 3 to rotate the set number of circles to control the opening and closing of the valve. There is no need to manually rotate the valve stem 3, which improves the accuracy of valve operation and does not require climbing onto the equipment to operate, thereby improving the safety of operation and not easily causing accidents.

[0023] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
