What Is Ball Valve Lock Overload?

 What is ball valve lock overload? Once a short circuit or overload occurs in a circuit or device, the air switch generates magnetic attraction with the coil in the circuit, opening the locking hook and disconnecting the circuit. The air switch essentially acts as a circuit breaker. At the same time, under the constraint of the locking pin and the connecting plate, the handle of the air switch on the secondary side of the substation cannot be turned upward.

As we all know, when using electricity at home, if the electric vehicle’s main power lock is turned on but the vehicle is not powered, it means the system integrates both control and various protection functions — serving as a safety warning.

In addition to completing the making and breaking of the circuit, it can also protect electrical circuits or equipment from short circuits, severe overloads, and undervoltage. When the main contact is closed through the operating mechanism, it is locked in the closed position by the locking hook. If a fault occurs in the circuit, the corresponding tripping device operates, causing the latch in the trip mechanism to release and the main contact to be opened by the spring.

Precautions for Using an Air Switch:
Ball valve lock overload refers to issues that may occur when the above mechanisms fail or are improperly installed. To address such problems, various types of air switches have been studied. By taking advantage of the air switch’s secondary side keyhole design, a locking pin and connecting plate are added to the keyhole, and a warning tag is hung on the locking pin to secure it.

The air switch, also known as an air circuit breaker, is a critical device in low-voltage power distribution networks and traction systems that integrates multiple protection functions. The tripping mechanism of the air switch is a set of linkages.

Installation Method for Air Switches:
Prepare the installation tools, turn off the main power supply, place the power distribution box on the reserved wall, neatly arrange the air switches in the slots, and then connect them after positioning. As for the installation method, a standard distribution box is not strictly required — any fixture capable of securing the air switch slots will work.

Industrial Locks: The “Special Forces” Guarding the Frontline of Safety

Image
 When we turn the key to our home, we rarely consider that in factories, power plants, chemical facilities, or large machinery, another class of locks is quietly fulfilling a much more demanding mission. These locks are not just for theft prevention—they face extreme environments, strict safety protocols, and life-or-death responsibilities. These are industrial locks, the indispensable “special forces” of the safety protection system. Beyond Household Use: The Unique Mission of Industrial Locks Unlike residential locks, the core functions of industrial locks revolve around functional safety and process control: Preventing Misoperation : Locking out energy sources (electricity, hydraulics, air) during equipment maintenance to ensure absolute safety—“locked means safe.” Access Control: Restricting access to hazardous areas or critical operations to authorized personnel only, enabling tiered management. Process Compliance: Enforcing adherence to procedural safety steps, preventing o...

How to Choose the Right Valve Lock for Different Needs

Image
Valve locks are relatively new to the domestic market, and product quality varies greatly among manufacturers. So, how can you select a valve lock that truly fits your needs? Here are some key points to consider: Opt for Trusted Brands or Authorized Dealers Choose reputable, long-established brands or certified distributors. Strong financial resources and a stable support system ensure reliable service and after-sales support, helping you avoid disputes caused by poor product quality. Know Your Valve Type Valves come in various forms — such as ball valves, butterfly valves, gate valves, and rotary valves . Make sure you know which type you’re working with so you can select the proper lock design. Select the Right Material for Your Environment Valve locks are available in different materials. Consider factors like air humidity, high-temperature exposure, or acid/alkali resistance to choose a lock built for your specific conditions. Check Compliance with Safety Standards...

Insulated Padlocks — A Solid Guarantee of Safety and Protection

Image
In modern society, as awareness of safety and protection continues to grow, the use of various safety devices has become increasingly widespread. Padlocks , as a common security tool, are widely used in homes, warehouses, factories, and other locations, serving multiple functions such as safeguarding property, preventing theft, and restricting unauthorized access. However, in certain special environments, ordinary padlocks are not sufficient—particularly in fields involving electrical installations and high-voltage power sources. Ordinary metal padlocks may pose serious risks if they come into contact with electricity, potentially causing severe electric shock accidents. To effectively address this problem, insulated padlocks were developed, becoming an essential tool for ensuring the safety of electrical facilities. Insulated Padlocks The core advantage of an insulated padlock lies in its electrical insulation properties. Traditional padlocks are usually made from metal, which is hi...
