Valve having remote control function

Abstract

The invention discloses a valve having a remote control function, and belongs to the technical field of valves. The valve comprises a valve body; the top end of the valve body is fixedly provided witha mounting shell; a servo motor is fixedly arranged in the mounting shell; an output shaft of the servo motor is fixedly connected with a drive bevel gear; the drive bevel gear and a driven bevel gear are engaged; and the driven bevel gear is fixedly arranged at the top end of a screw. A bi-stable trigger is employed as a control input part; every time a pulse is input, conversion is carried outfor one time to perform negative rotation and positive rotation control and realize negative rotation and positive rotation operation of the servo motor, and then, a valve plate can stably move vertically under the action of the screw, and thereby, remote control operation is realized; the control effect is good; the valve is suitable for automation equipment; and the flow condition after the valve is opened is calculated by a digital flow meter in real time, and is sent to a control terminal in real time by a remote function, and thus, a worker is facilitated to perform data recording and statistics, and functions are perfected to be diversified.

Description

technical field [0001] The invention belongs to the technical field of valves, in particular to a valve with a remote control function. Background technique [0002] Valves are the control components in the fluid delivery system. They have the functions of cut-off, adjustment, flow diversion, reverse flow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems range from the simplest cut-off valve to extremely complex The various valves used in the automatic control system have a wide variety of varieties and specifications. The valves 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. . [0003] At present, most of the existing valves are controlled manually or electrically, the remote control function is not perfect, the use effect is not good, and it does not have the function of flow calculation, it is dif...
