Embodiment Construction

[0024] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0025] Such as figure 1 as well as figure 2 As shown, the valve in this embodiment is a butterfly valve, and the butterfly valve includes a handle 1, a valve body 2, and a valve stem 3 (the valve stem can also be operated by other valves with the same or similar functions as the valve stem) Control piece), an upper indicator plate 4 and a lower indicator plate 5 sleeved on the valve stem 3, a magnetic induction reed switch 6 is embedded on the lower indicator plate 5, and a magnetic induction reed switch 6 is embedded on the upper indicator plate 4. Through the hole, the upper indicating plate 4 and the lower indicating plate 5 are butted against each other, and the distance between them is also very close. A permanent magnet 7 is provided at the lower end of the handle 1 . Wherein, t...

Abstract

The invention discloses a valve, which comprises a mobile end and a valve main body, wherein the mobile end is fixedly arranged on the valve main body and is used for controlling the opening and the closing of the valve through a valve operating control element, the valve is characterized in that a signal sending device is arranged on the mobile end and is used for sending an action signal, the valve main body is provided with a stationary end, a signal receiving device is arranged on the stationary end and is used for receiving the action signal, and the signal receiving device receives the action signal when the valve is closed. The opening and closing state of the valve can be automatically detected through the signal sending device and the signal receiving device, so that the valve with the advantages of accuracy, high speed, controllability and intelligence is provided, the opening and closing state of the valve is prevented from being operated and monitored manually, and the requirement of rapidly-developed modern production is met.

Description

technical field [0001] The invention relates to a valve, in particular to an intelligent valve for a mobile storage tank which can automatically detect the switching state through a signal sending device and a signal receiving device. Background technique [0002] Valves are the control components in the fluid delivery system. They have the functions of cut-off, adjustment, diversion, prevention of reverse flow, pressure stabilization, diversion or overflow pressure relief. Valves can be used to control air, water, steam, various corrosive media, mud, etc. , oil, liquid metal and radioactive media and other types of fluid flow. Due to the needs of production and transportation, the butterfly valves used on container tanks containing chemical raw materials must be accurate, high-speed, controllable, and intelligent. The switching status of current butterfly valves must be manually operated and monitored by staff. . During the transportation of the container tank, if there i...
