Multifunctional performance testing device

Abstract

The invention provides a multifunctional performance testing device, and belongs to the field of testing equipment. The multifunctional performance testing device comprises a workbench, a control center and a fixed mount, wherein the control center and the fixed mount are arranged at an upper end face of the workbench, the fixed mount comprises a first fixed plate and a second fixed plate arrangedin parallel, the second fixed plate is provided with a driving cylinder, an output shaft of the driving cylinder is arranged in the form of vertically passing through the second fixed plate, the output shaft of the driving cylinder is provided with a pressing plate in threaded connection, the first fixed plate is provided with a locating hole, a butterfly valve is arranged between the locating hole and the pressing plate, a valve rod at an upper end of the butterfly valve is connected with a pneumatic actuator, and the control center controls execution of all electrical apparatus element actions. The multifunctional performance testing device is simple in structure, convenient to operate and capable of visually observing a result of testing; and the structure can be used for testing service life and performance of the butterfly valve, the driving cylinder and the actuator, and can be used widely.

Description

technical field [0001] The invention belongs to the field of performance testing and relates to a multifunctional performance testing device. Background technique [0002] Butterfly valve, also known as flap valve, is a regulating valve with simple structure, which can be used for switch control of low-pressure pipeline medium. A kind of valve, the valve can 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. It mainly plays the role of cutting and throttling on the pipeline. The opening and closing part of the butterfly valve is a disc-shaped butterfly plate that rotates around its own axis in the valve body to achieve the purpose of opening and closing or adjustment. [0003] Butterfly valve not only has simple structure, small size, light weight, low material consumption, small installation size, small driving torque, easy and fast operation, but also has good flow regul...

AI Technical Summary

Problems solved by technology

[0003] Butterfly valve not only has simple structure, small size, light weight, low material consumption, small installation size, small driving torque, easy and fast operation, but also has good flow regulation function and closing and sealing characteristics. Butterfly valve is a practical application that needs to go through Life test, to ensure sufficient rotation performance and tightness during use. The current common butterfly valve life test device cannot intuitively observe the state of the butterfly valve during the test process. The test is completed according to the set time, and the test structure is not accurate enough.
