On March 1st, Anhui Puyang Municipal Government and Heyang Hefei Modern Industrial Park together with AVIC Electromechanical Systems Co., Ltd. and Anhui Jianghuai Automobile Group Co., Ltd. signed an investment framework agreement for the CAAC-Jianghuai Special Vehicle Chassis Manufacturing Base Project in Hefei. According to the agreement, AVIC and JAC will spend RMB 1 billion to build special vehicle chassis and vehicle manufacturing bases in the Bengbu Modern Industrial Park to jointly promote the development of related supporting industries and form an automobile and parts industry cluster with over one billion yuan in Xiangyang. .
Yu Yong, Party Secretary of Fuyang City, Cao Longcan, Member of the Standing Committee of the Municipal Party Committee and Deputy Mayor, An Li, Director of the Management Committee of the Modern Industrial Park; Lu Weijia, Deputy General Manager of AVIC Mechanical & Electrical Systems Co., Ltd., Chairman of Anhui Jianghuai Automobile Group Co., Ltd. President An Jin attended the signing ceremony.
JAC is a comprehensive automobile manufacturer integrating R&D, manufacturing, sales and service of commercial vehicles, passenger vehicles and powertrains. It has a complete independent innovation R&D system and a nationwide automotive sales network, with an annual output of 70 The production capacity of 10,000 vehicles, 500,000 engines and core components. AVIC is directly subordinate to China Aviation Industry Corporation and has three listed companies. Its special vehicle production units have the capacity to produce 80,000 vehicles of all types and 100,000 micro-cards annually. AVIC and JAC will jointly build a special vehicle chassis manufacturing project in the Bengbu Modern Industrial Park with a total investment of 1 billion yuan and an area of ​​about 500 mu. It will mainly produce chassis for military and civilian-use vehicles, as well as R&D, manufacturing and sales of complete vehicles. With an annual output of 30,000 special-purpose vehicles chassis and vehicles, the annual output value will be 5 billion yuan and tens of thousands of jobs will be provided. After the special vehicle chassis and vehicle manufacturing base are completed, they will form an agglomeration effect with Anhui Kaile Special Vehicle Co., Ltd. to promote its transformation from a single refitted production to a complete vehicle production, jointly spur the development of related supporting industries, and form a super development in Fuyang. The billion-dollar automobile and parts industry cluster has greatly increased the status of Fuyang in the province's automotive industry.
Yu Yong said at the signing ceremony that the CAAC-Jianghuai special vehicle chassis manufacturing project entered the Shuhe Hyundai Industrial Park, which shows that the provincial party committee and provincial government, as well as the central and provincial enterprises attach great importance to the development of Shuyang, and will certainly accelerate the development of Liyang. Have a positive effect. The municipal party committee and the municipal government will provide good services and policy support, create a good development environment for the company, and promote the early construction of the project, early production, and early performance.
Lu Weijia and An Jin said that paying attention to and supporting local economic development is an important responsibility of central and provincial enterprises. The next step will be to strengthen exchanges and cooperation with Xiangyang City, speed up project construction, and urge projects to be put into production as soon as possible for the development of Xiangyang Automobile Industry. contribution.
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.
