Problems solved by technology

Because, if the actual manual cut-off valve is used, then the actual material must be passed through the teaching and training device to form a real fluid flow change, which causes the teaching and training device to be complicated in production and testing, high in cost, large in investment, and diffi

Example Embodiment

[0021] Embodiment: The structure of the electronic two-position manual shut-off valve in this embodiment is as attached figure 1 As shown, it mainly includes a manual shut-off valve. Its main feature is that the manual shut-off valve is connected with a state display instrument through the signal line 1. The state display instrument housing 5 has a position sensor, a signal converter, an output circuit, and two LED states. Display light 4.

[0022] In order to achieve a simulation and practical effect, the shape is a combination of actual spherical manual shut-off valve and rectangular column-shaped thematic display instrument. The manual shut-off valve has an operating handle 13, a handle fixing nut 14, and a valve stem (connected with a spool) 12. The valve body 10, the fixed nut 8, the fixed screw 11 and the valve connection screw 9 (with internal thread) are composed, and the rotation position of the operating handle (0~90 o ) Convert to the open and closed state of the spool...

Abstract

The invention belongs to the technical field of teaching aids and relates to a manual stop valve, which is applied in a fluid delivery pipeline of a simulation teaching and training device in the process of industrial production and is provided with an opening/closing state display lamp. The invention mainly comprises the manual stop valve and is characterized in that the manual stop valve is connected with a state display instrument through a signal line; and a position induction sensor, a signal converter, an output circuit and two light-emitting diode (LED) display lamps are arranged in a shell of the state display instrument. The manual stop valve has the functions that an electronic manual stop valve simulates an actual stop valve, and the LED lamps display the change of the opening/closing state and can output a digital signal corresponding to the opening/closing state to a control station of a control room. The manual stop valve has the advantages of convenience for operation, remote transmission, practicality, intuitional and eye-catching display, wide perspective view, far sight line, compact and reliable structure, using flexibility, safety, reliability, no phenomena of fluid running, overflowing, dripping and leaking, less maintenance, low maintenance cost, long service life and the like, and is an ideal electronic dual-position manual stop valve.

Description

technical field [0001] The invention belongs to the technical field of teaching aids, and relates to an electronic double-position manipulator with switch state display, in particular to a manual cut-off valve with switch state display lamp applied to a fluid delivery pipeline of a simulation teaching training device in an industrial production process. Background technique [0002] A valve is a device used to control the direction, pressure, and flow of a fluid in a fluid delivery system. This type of valve is a device installed in the process pipeline to make or stop the medium in the piping and equipment and to control its flow. [0003] The valve is a control component in the pipeline fluid delivery system. It is used to change the medium flow area and medium flow direction, and has functions such as diversion, cut-off, throttling, check, diversion or overflow pressure relief. Valves used for fluid control range from the simplest cut-off valve to the various valves used...
