China Automobile Industry Association released the list of China's MPV (multi-purpose vehicles) sales in October 2014. The three MPV products produced by Wuling Hongguang, Baojun 730 and Dongfeng Liuqi produced by Guangzhou Liuzhou Automobile Company, SAIC-GM-Wuling, are popular. , occupying the top three in the sales list, and monopolizing more than 60% of China's MPV market.
The list shows that Wuling Hongguang and Baojun 730, which are known as the world's most successful joint ventures, are the most eye-catching in the production of 60,500 vehicles and 25,506 vehicles. Dongfeng Liuqi's popular productions of Jingyi and Fengxing Lingzhi ranked third and sixth with sales of 13,050 vehicles and 9,500 vehicles.
According to the data of the China Automobile Association, China sold a total of 178,321 MPVs in October, a year-on-year increase of 35.9%. The four MPV products produced by Liuzhou Automobile Company sold 108,556 units in October, accounting for 60.9% of the Chinese market.
Among the major consumer clusters of MPV cars in China's second- and third-tier cities, MPVs with low prices, large space and practical configuration can meet the needs of Chinese auto consumers for both home and business use, and thus have won the favor of many Chinese consumers.
From January to October this year, China's MPV sales totaled 1,466,856 units, a year-on-year increase of 44%, while Liuzhou's four MPV products sold 859,925 units in the first 10 months, accounting for 58.6% of China's total sales.
Lu Hao, chief engineer of the Liuzhou Industrial and Information Committee, said that China's auto market is upgrading and user demand is upgrading. SAIC-GM-Wuling and Dongfeng Liuqi are keenly aware of the changes in demand in the main market with a unique strategic vision. The 7-seat MPV for home and business is defined as a key category for future product development, thus occupying a strong share of the Chinese MPV market.
Liuzhou, Guangxi, which has the production base of China's four major automobile groups, officially plans to produce 2.5 million vehicles in Liuzhou by 2015.
Air valve
The new double-canisters exhaust valve consists of a big canister and a small one.
When there is no water in the pipe, the canister in the body drops down to the full opening place. When water coming in, the air in the body is released from the big canister, then water can be filled into the pine immediately. When there is no air in the pipe, water comes into the valve cavity and causes the two canisters rise up to the closing place. And the big canister stays closed so as to improve the capacity of transporting water and to economize energy.Since air is often dissolved into water, when transporting water, the air is released from water continuously , however, when reaching the quantity, the small canister will drop down with a small amount of air released from air vents . Otherwise the air accumulating on the top of the pipe will reduce the pipe system`s capability of transporting water.
When there is negative pressure in the pipe, the big canister drops down and the discharge hole is open. Then the valve takes in air in good time so that it can avoid affecting normal water supply due to the negative pressure on the pipe.
1.Unique design:
The two canisters are made of non-toxic engineering plastics of high strength., with concise structure, light weight, reliable and stable exhausting.
Inside and outside surfaces of the body, cover and dust-prevented cap are all coated with epoxy resin powder with no iron exposed. Materials of inner components are made of stainless steel and engineering plastics so as to prevent corrosion and to ensure purity of media.
The sealed seat, made of bronze, improves the ability of anti-abrasion, and prolongs service life.
2.Excellent anti-corrosion:
Inside and outside surfaces of the body, cover and dust-prevented cap are all coated with epoxy resin powder with no iron exposed
3.Sanitary standard:
Non-toxic epoxy resin powder used comply with sanitary standard GB/T 17219-1998.The coated resin is in accordance with standards of drinking water.
4.Tested summary:
The media is air. In the procedure of the test, the air temperature shall keep between 5℃ and 45℃. The fluctuation of air flowing value shall be within 4% and that of the pressure value within 5% while that of air temperature value within 2%.
Sealing test at a low pressure. When the pressure goes up to 0.05 Mpa, 0.1 Mpa, 0.2 Mpa, 0.3 Mpa, 0.4 Mpa, 0.5 Mpa, the valve maintains the pressure at 12mins with no visually detectable leakage of the sealed surface.
Repeated test of exhausting Putting water into the valve and discharging air every 8-9 seconds. Then increasing the pressure to 1.6 Mpa , keeping it for 2mins before releasing. Conducting leakage test for 250 times with the result that there is no visually detectable leakage and no structural damage. Then testing the sealing at a high as well as low pressure, no visually detectable leakage.
Repeated test of airing Injecting air into the valve till the valve closes fully, then cutting off the air till the valve open fully. Repeating leakage tests for about 25000 times with the consequence of no visually detectable leakage and no structural damage. Then testing the sealing at a high as well as low pressure, no visually detectable leakage.
Test of the valve's endurance The valve is poured by water with a pressure of 1.6 Mpa at a temperature of 50℃and maintaining it for five days, then checking whether the valve can be normally opened or not after releasing the pressure.Testing the leakage, resulting in no visually detectable leakage and no structural damage. Then testing the sealing at a high as well as low pressure, no visually detectable leakage.
