Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing design cannot realize the rapid adjustment and opening and closing of the valve under the condition of high pressure in the high-density liquid pipeline, and the existing design can only be driven by the motor. If there is a power failure or the motor fails The valve cannot be opened and closed normally, and a high-density liquid pipeline fast-adjusting valve is proposed. Compared with the existing design, the present invention is equipped with a labor-saving mechanism inside the device body, so that the motor does not need to output excessive torque when it is working. , can be well qualified for the task of fast opening and closing of the valve, and at the same time, by setting up a labor-saving mechanism, the user can also manually open and close the valve in case of power failure or motor failure

Abstract

The invention discloses a high-density liquid pipeline rapid adjusting valve and belongs to the technical field of pipeline valves. The high-density liquid pipeline rapid adjusting valve comprises aninstallation shell and an installation frame, wherein a valve pipe body is installed inside the installation shell, two ends of the valve pipe body are fixedly connected with a water inlet pipeline and a water outlet pipeline respectively, and reinforcing ribs are fixedly connected outside the water inlet pipeline and the water outlet pipeline; and the installation frame is fixedly connected to the top end of the installation shell, a connecting frame is fixedly connected to the periphery of the installation frame, the installation frame and the connecting frame are matched with an electric adjusting device, the lower end of the electric adjusting device is mounted inside the installation shell, and one side of the installation shell is connected with a manual adjusting device. The high-density liquid pipeline rapid adjusting valve effectively solves the problems that a valve cannot be quickly adjusted and opened and closed well under the condition that the pressure in a high-density liquid pipeline is high in an existing design, the existing design can only be driven by a motor, and the valve cannot be normally opened and closed if the power is cut off or the motor fails.

Description

Technical field [0001] The invention relates to the technical field of pipeline valves, in particular to a fast-adjusting valve for high-density liquid pipelines. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control flow, adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc.; The valve is a control component in the fluid conveying system, which has the functions of cut-off, regulation, diversion, prevention of backflow, stabilization, diversion or overflow and pressure relief. The valves used in fluid control systems, from the simplest shut-off valves to the various valves used in extremely complex automatic control systems, have many varieties and specifications; for some pipelines used to transport high-density liquids, ordinary valves are not Applicable, therefore, it is very nece...
