Ratchet Buckles are the one of the most important part of ratchet lashing belts.
They fuction as the adjuster of the webbing,by treading the webbing through the axel,and ratcheting it back and forth,that's how we manage to tighten the webbing,is also called Ratchet Tensioner.
The most didely-used ratchet buckle is galvanized buckles.And sometimes we can see other kinds like black electrophretic painted buckle,powder painted buckle,and some non-standard buckles.
Apart from its surface treatment,we can also tell buckles can be sorted by its inside width,they are the almost same with webbings,so we have 1'' buckle,2'' buckle,3'' buckle,etc.

The new valve technology is cleaner and smoother will become the mainstream market
Traditional valves, such as butterfly valves, slide valves and gate valves, present problems of hygiene and resistance to flow when powdering. Usually all of these devices are placed at the bottom of a rigid RIBC, hopper, feeder or silo, many of which are immersed in the powder. The characteristics of the powder make it difficult to flow smoothly through the valve, often bridging, empty or rushing phenomenon. Bridging occurs when the powder backlog does not flow on both sides of the valve. Voids are also caused by powder retention, with small holes in the middle where the powder flows out of the hole. The opposite of powder overstuffing and poor flow is rushing and unable to control the flow of powder. Auxiliary equipment to avoid the formation of bridges and hollows in the container wall or hopper to add a vibrator or air cannon, sometimes you may also see an operator next to the hopper hopper with a hammer side. Although these methods are somewhat helpful to the flow of powders, they tend to exacerbate the situation and produce new backlogs, clumps or runs. And easy to bring noise pollution and feeder damage. There are also hopper shakers that can help reduce flow problems, but its downside is that there are no valves to stop the flow of powder and no meters to control the flow. A more well-designed system with a hopper shaker should also include block valves and metering equipment or feeders. But this takes up more overhead space, more maintenance and more costs. Cone Valve Technology In the early 1980s, cone valve technology entered the market, combining the benefits of improved flow with some of the features of a conventional valve. One of the leaders in the industry, Material Control Engineering, now the company Matcon, has unveiled the integration of metering, unloading and valves into what Matcon cone valves are today. Ivan Semenenko, inventor and founder of the cone valve, is the key to pushing this technology to the forefront of powder processing. This equipment includes a pneumatic, tapered inner layer that acts as a bridge to break the bridge when lifted, and a valve that acts as a valve to the RIBC container as it descends. The flow rate can be controlled by controlling the frequency at which the cone valve is raised and lowered. In the 1980s, this technology gradually lost its market due to the presence of many imitators and competitors. It is just a transition from the unloader to the traditional valve, and early devices still had some inherent problems. Ideally, the simpler the valve should be, the fewer the parts the better and be isolated from the flow of powder. However, nearly 100 parts of Matcon and other companies are designed to come into contact with the powder stream, easily causing product contamination and cross-contamination. Since many parts are dipped in the powder stream, the chances of failure are high, and the amount of maintenance required for earlier designs is substantial. Another major problem is that the tapered layer may move slightly, disrupting the tightness with the RIBC nozzle. New technology 18 years later Ivan Semenenko founded a new company specializing in the inherent problems of early cone valves. Semenenko's company ISL Cone-Valve took two years to develop a new type of conical valve that solved the problem. The new design includes a conical valve and a transfer hopper. The valve is placed in the RIBC or in the hopper with a sanitary gasket on the mouth of the RIBC. A transfer hopper with an expansion device and probe is also part of the unloading station. As the RIBC is lowered, the expansion device lifts the probe vertically to lift the conical valve so that the powder can flow through the transfer hopper without touching the valve, thus avoiding valve contamination. Semenenko simplifies the design and reduces the need for maintenance, the components are reduced to only six. A maintenance worker can do the disassembly and removal in minutes instead of the traditional cone valve which can take hours. The new cone valve has no mechanical parts immersed in the powder flow, there will be no tilt leakage, and the flow rate variable. For traditional valves, whether butterfly valves, rotary valves, iris valves or other types, there is a phenomenon that the valve is hard to hold when the powder flow force is very large, and the powder continuously flows out. The use of conical valves to solve this problem. The momentum of the powder stream helps to close the valve, but the older conical valve will have trickle flow at the outer edge. The new conical valve reduces the valve to 15mm from the edge before completely closing the valve, and then completely closes the valve after the residual powder flows below it, thus avoiding leakage. The valve uses a simple external sensor to change the lifting height of the cone and has the function of continuous adjustment, which can be adjusted according to the specific situation, such as viscous powder which is not easy to discharge. Applications The vast majority of RIBC systems used in the pharmaceutical, food and chemical industries use tapered valves. In addition to its use in hoppers and silos, ISL cone valve technology has recently also been used in bulk container systems (FIBCs). By partnering with bulk bag manufacturers, ISL is pushing conical valve technology to the broader powder processing industry. Both new and older users benefit from this new technology, installing the new cone valve upgrade kit with minimal changes for the same benefits as new equipment. Thanks to this simple, clean conical valve design, this device is ideally suited for the food and pharmaceutical industries. In addition, the conical valve has always been used in the chemical and plastics industries. Conclusion The new conical valve caters to the less maintenance, fewer failures, measurable, fully enclosed requirements, eliminating the user's worries.
