Description

Technical Field

[0001] The utility model relates to the technical field of valves capable of detecting flow interruption, in particular to a valve capable of detecting flow interruption. Background Art

[0002] The gate is a control component in the fluid conveying system, which has the functions of shutting off, regulating, guiding, preventing backflow, stabilizing pressure, diverting or overflowing pressure relief. The valve is a pipeline accessory used to open and close the pipeline, control the flow direction, and adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to its function, it can be divided into shut-off valves, check valves, regulating valves, etc. Valves can also be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media.

[0003] Most of the valves that can detect flow interruption realize whether the flow is interrupted or not by means of a pressure sensor installed inside the valve. Most of the existing valves that can detect flow interruption are installed by means of flanges and bolts. These bolts are scattered and not fixed in a certain place. As a result, when installing the valve, the staff need to prepare to find the bolts, which wastes time and is not conducive to the staff's use. For this reason, we propose a valve that can detect flow interruption. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a valve capable of detecting flow interruption, which is used to solve the above problems.

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

[0006] A valve capable of detecting flow interruption comprises a valve body, an inner wall of which is fixedly mounted a pressure sensor, both ends of the valve body are fixedly connected with discs, the outside of the disc is fixedly connected with four equally spaced fixed plates, the outside of the fixed plate is provided with a rotating assembly, the top of the fixed plate is fixedly connected with a fixing frame, the outside of the fixing frame is provided with a fixing assembly, and one side of the disc is provided with a mounting assembly.

[0007] Preferably, the rotating assembly includes a through slot opened on one side of the fixed plate, and the inner walls of the through slot are rotatably connected to the same rotating shaft on both sides. The rotating shaft extends to one side of the fixed plate, and the outside of the rotating shaft is fixedly connected to a rotating plate. The rotating plate can be rotated by setting the rotating assembly.

[0008] Preferably, the installation assembly includes a threaded rod threadedly connected to one side of the rotating plate, and four equidistantly distributed threaded holes are opened on the outside of the disc. The threaded rod and the threaded holes are adapted to each other. By setting the installation assembly, the valve body can be fixedly connected to the pipeline.

[0009] Preferably, a first handle is fixedly connected to one side of the threaded rod, and the first handle is made of rubber. By providing the first handle made of rubber, the comfort of the staff when holding the first handle is improved.

[0010] Preferably, the fixing component comprises a plurality of equally spaced sockets provided outside the rotating shaft, a plug rod is movably connected to the top of the fixing frame, the plug rod is adapted to the sockets, and the rotating shaft can be fixed by setting the fixing component.

[0011] Preferably, a second handle is fixedly connected to the top of the insertion rod, and the second handle is made of rubber. By providing the second handle made of rubber, the comfort of the staff when holding the second handle is improved.

[0012] Compared with the prior art, the beneficial effect of the utility model is as follows: when the valve body needs to be installed on the pipeline, the valve body is first aligned with the pipeline, at which time the disc of the valve body contacts the flange of the pipeline, and then the rotating plate is rotated, and the rotating plate rotates through the rotating shaft. At this time, the first handle is held and rotated, and the threaded rod can be driven to rotate when it moves through the rotation of the first handle. At this time, the threaded rod passes through the hole opened on the flange, and then the threaded rod will be screwed into the threaded hole opened on the disc, and the valve body can be fixed on the pipeline, and the plug rod can be inserted into the inside of the plug hole by pushing the second handle, and the rotating shaft can be fixed, and the pressure sensor is set, so that the valve body has the function of detecting flow interruption. Through the above structure, it is convenient for the staff to install and fix the valve body on the pipeline, and the installation operation is simple, avoiding the traditional use of non-fixed bolts for installation, resulting in the need to prepare to find bolts during installation, wasting time, and greatly facilitating the use of the staff.
