Why LED lighting companies actively explore the rural market
Why do you want to go to the township to run the market, because the Xingan International Lighting City is going to take the rural encirclement of the city, logistics to seize the market route.
According to statistics, there are 773 townships in Jiangxi. If there are 2 lighting stores in each township, then there will be more than 1,500 township lighting stores in Jiangxi. This number represents a huge channel network, and this network has always been hidden, so as long as this channel network is thorough and deep, the prospects are very broad.
From March 26th to April 4th, the marketing department of Xingan International Lighting City went deep into the Shangrao area and Zhangzhou area. Under the guidance of Manager Lei, the sales department of the marketing department conveyed the notice of free customer pick-up and delivery of Xingan International Lighting City to the county towns and townships of the Zhangzhou area and Shangrao area in line with the principle of fine digging and fine farming.
In today's channel-based, terminal-based lighting industry, some rural consumers are often overlooked. According to the response of Xingan International Lighting City to the merchants: the current rural consumers are willing to spend money and are willing to spend money! And most of the rural families in Jiangxi are mainly three-story small buildings, the decoration area is very wide, and the demand for lamps is very large. Therefore, tapping rural consumers and driving the new wave of rural lighting consumption can not be ignored in the entire lighting industry, and it is also necessary for Xingan International Lighting City to create a wholesale market!
The reporter ran all over Jiangxi and heard many county dealers react: Most of the dealers in the county have a large part of their business scope, because many of the county-level dealers currently have 15 dealers, some even surpassing 20 Home, this has led to increased competition and reduced market demand. The rural area is a piece of tea that determines the market's survival of the fittest. Whoever seizes it will be able to stabilize the entire county market. Therefore, to do a good job in rural areas, so that the remaining two or three dealers in each township can be profitable and available, then this will threaten the county's more than ten dealers. In turn, driven by the profitability of rural distributors, the channel of Xingan International Lighting City will begin to extend to the county, and since then, it will extend to the city until it threatens the provincial capital Nanchang!
Xingan International Lighting City is like a heart. Xingan International Lighting City's self-built logistics is like blood distributed in Jiangxi. Without this critical self-built logistics, the strategic direction of rural encircling the city will be difficult to achieve. On March 25th, a customer of Zixi purchased 26 lamps from Xingan International Lighting City. On the afternoon of March 25th, in order to deliver these goods to the customer's shop on time, the logistics driver will not hesitate to drive back and drive the 800-kilometer mountain road and go to Xingan and Zixi overnight. For 26 pieces of lamps and lanterns, Xingan International Lighting City's logistics services have earned credibility at a loss. There is no reason for such a market to not be strong or bigger.
REGULATORS
You must be able to reduce the high-pressure gas in a cylinder to a working pressure before you can use it. This pressure reduction is done by a regulator or reducing valve. The one basic job of all regulators is to take the high-pressure gas from the cylinder and reduce it to a level that can be safely used. Not only do they control the pressure but they also control the flow (volume of gas per hour).
Regulators come in all sizes and types. Some are designed for high-pressure oxygen cylinders (2,200 psig), while others are designed for low-pressure gases, such as natural gas (5 psig). Some gases like nitrous oxide or carbon dioxide freeze when their pressure is reduced so they require electrically heated regulators.
Most regulators have two gauges: one indicates the cylinder pressure when the valve is opened and the other indicates the pressure of the gas coming out of the regulator. You must open the regulator before you get a reading on the second gauge. This is the delivery pres-sure of the gas, and you must set the pressure that you need for your particular job.
The pressures that you read on regulator gauges is called gauge pressure. If you are using pounds per square inch, it should be written as psig (this acronym means pounds per square inch gauge). When the gauge on a cylinder reads zero, this does not mean that the cylinder is empty. In actuality, the cylinder is still full of gas, but the pressure is equal to the surrounding atmospheric pressure. Remember: no gas cylinder is empty unless it has been pumped out by a vacuum pump.
There are two types of regulators that control the flow of gas from a cylinder. These are either single-stage or double-stage regulators.
Single-Stage Regulators
Regulators are used on both high- and low-pressure systems. Figure 4-8 shows two SINGLE-STAGE regu-lators: one for acetylene and one for oxygen. The regulator mechanism consists of a nozzle through which the gases pass, a valve seat to close off the nozzle, a diaphragm, and balancing springs. These mechanisms are all enclosed in a suitable housing. Fuel-gas regulators and oxygen regulators are basically the same design. The difference being those designed for fuel gases are not made to withstand the high pressures that oxygen regulators are subjected to.
Figure 4-8.-Single-stage regulators.
In the oxygen regulator, the oxygen enters through the high-pressure inlet connection and passes through a glass wool falter that removes dust and dirt. Turning the adjusting screw IN (clockwise) allows the oxygen to pass from the high-pressure chamber to the low-pressure chamber of the regulator, through the regulator outlet, and through the hose to the torch. Turning the adjusting screw further clockwise increases the working pressure; turning it counterclockwise decreases the working pressure.
The high-Pressure Gauge on an oxygen regulator is graduated from 0 to 3,000 psig and from 0 to 220 in cubic feet. This allows readings of the gauge to deter-mine cylinder pressure and cubic content. Gauges are calibrated to read correctly at 70°F. The working pres-sure gauge may be graduated in [psig" from 0 to 150, 0 to 200, or from 0 to 400, depending upon the type of regulator used. For example, on regulators designed for heavy cutting, the working pressure gauge is graduated from 0 to 400.
The major disadvantage of single-stage regulators is that the working gas pressure you set will decrease as the cylinder pressure decreases; therefore, you must constantly monitor and reset the regulator if you require a fixed pressure and flow rate. Keeping the gas pressure and flow rate constant is too much to expect from a regulator that has to reduce the pressure of a full cylinder from 2,200 psig to 5 psig. This is where double-stage regulators solve the problem.
Double-Stage Regulators
The double-stage regulator is similar in principle to the one-stage regulator. The main difference being that the total pressure drop takes place in two stages instead of one. In the high-pressure stage, the cylinder pressure is reduced to an intermediate pressure that was predetermined by the manufacturer. In the low-pressure stage, the pressure is again reduced from the intermediate pressure to the working pressure you have chosen. A typical double-stage regulator is shown in figure 4-9.

Problems and Safety
Regulators are precise and complicated pieces of equipment. Carelessness can do more to ruin a regulator than any other gas-using equipment. One can easily damage a regulator by simply forgetting to wipe clean the cylinder, regulator, or hose connections. When you open a high-pressure cylinder, the gas can rush into the regulator at the speed of sound. If there is any dirt present in the connections, it will be blasted into the precision-fitted valve seats, causing them to leak This results in a condition that is known as creep. Creep occurs when you shut of the regulator but not the cylinder and gas pressure is still being delivered to the low-pressure side.
Regulators are built with a minimum of two relief devices that protect you and the equipment in the case of regulator creep or high-pressure gas being released into the regulator all at once. All regulator gauges have blowout backs that release the pressure from the back of the gauge before the gauge glass explodes. Nowadays, most manufacturers use shatterproof plastic instead of glass.
The regulator body is also protected by safety devices. Blowout disks or spring-loaded relief valves are the two most common types of devices used. When a blowout disk ruptures, it sounds like a cannon. Spring-loaded relief valves usually make howling or shrieking like noises. In either case, your first action, after you recover from your initial fright, should be to turn off the cylinder valve. Remove the regulator and tag it for repair or disposal.
When opening a gas cylinder, you should just [crack" the valve a little. This should be done before attaching the regulator and every time thereafter. By opening the cylinder before connecting the regulator, you blow out any dirt or other foreign material that might be in the cylinder nozzle. Also, there is the possibility of a regulator exploding if the cylinder valve is opened rapidly.
WARNING
Oil or other petroleum products must never be used around oxygen regulators because these products will either cause a regulator explosion or fire
