Problems solved by technology

[0002] The valve is a pipeline accessory used to open and close the pipeline and control the flow direction. The valve and the pipeline are directly connected and installed. The opening and closing of the valve is controlled by the valve handwheel. The existing valve handwheel needs to be manually rotated by the staff. The valve In some important installation occasions, it is necessary to use locks to lock the valve, so as to prevent idlers from completing the opening and closing of the valve by turning the valve handwheel, causing unnecessary financial losses and even safety accidents.
[0003] The locking of valves is nothing more than traditional mechanical locks that use keys to unlock and electronic locks that are currently being developed. The advantages of mechanical locks are that they are cheap and the unlocking method is stable. The most common scenario is that the operation and maintenance operators carry a tool bag with a pile of heavy chain locks, metal padlocks and safety signs in the bag. When operating in the underground factory, they register the key numbers of the metal padlocks one by one, and after the operation Immediately and carefully put these keys back into the "second-class key cabinet" one by one. The convenience of the lock switch is low, time-consuming and labor-intensive. It is very important to have a sense of responsibility and work responsibility (to master all current work tickets), and the work pressure of personnel is also very high.
[0004] Electronic lock is an electronic product that controls the circuit or chip work (access control system) through password input, so as to control the closing of the mechanical switch and complete the task of unlocking and locking. It is currently widely used in door locks. The core is realized by programming, and its main components are: single-chip microcomputer, clock, keyboard, LCD display, memory, demodulator, line multiplexing and monitoring, A / D conversion, buzzer and other units, which overcome the mechanical However, whether it is a fingerprint combination lock or a digital combination lock, it requires the cooperation of a professional processing chip and a sensor to realize the switching requirements, and its high cost is not suitable for water pumping. Applicable occasions with hundreds of valves such as energy storage power stations
[0005] Therefore, the existing valve lock has the problem that the cost of the lock, the convenience of the lock switch and the safety of the lock cannot be taken into account at the same time.

Embodiment

[0034] Embodiment: an intelligent safety isolation valve with a structure such as figure 1 As shown, including the isolation valve body, the hand wheel of the isolation valve body is fixed with an electronic lock with a telescopic bolt and a lock box, and the bracket tube of the isolation valve body is welded with a lock plate that cooperates with the telescopic bolt; the electronic lock is controlled by a voltage The adjustable switching power supply is used for power supply, and the real-time voltage output by the switching power supply is used as the password for the switch of the electronic lock.

[0035] The overall structure diagram of the switching power supply is as follows figure 2 As shown, the adjustment range of the output voltage is 0-24V, and the step voltage is adjusted by pressing the button with 0.1V or 1V. The present invention can set a 3-digit password in advance, and theoretically can choose between 00.0-23.9.

Abstract

The invention discloses an intelligent safety isolating valve comprising an isolating valve body. An electronic lock with a telescopic bolt, and a lock box are fixed to a hand wheel of the isolating valve body. A lock disc is welded to a support barrel of the isolating valve body and is matched with the telescopic bolt. A voltage-adjustable switching power supply supplies power to the electronic lock, and the magnitude of the real-time voltage output by the switching power supply serves as an unlocking and locking password of the electronic lock. The intelligent safety isolating valve has the advantages that lock cost is low, the convenient degree of unlocking and locking of the lock is high, and the lock safety is good.
