Helping green building materials to develop mechanical equipment also needs intelligence
At present, China is still in the mid-stage of industrialization. During the period of new normal economic development, building materials machinery and equipment have largely failed to meet the requirements for the development of green manufacturing.
According to Shen Xuewu, deputy general manager of Wuhan Tongli Intelligent Systems Co., Ltd., a master of science, doctor of management, postdoctoral of management science and engineering, there are still many problems in the development of building materials machinery and equipment. For example: over-reliance on factor input, economic efficiency is not high; technological innovation system needs to be improved; large enterprise groups are not strong, lack of supporting specialized fine small enterprises; lack of high-level industry professionals; intelligence is not high.
To assist the development of the green building material industry chain, it is necessary to crack down on the difficulties of building materials machinery and equipment. Therefore, the building materials machinery and equipment in the future need to develop from the following aspects:
Focus on technology integration, industrial integration and management integration in three aspects and information integration.
Adhere to the "five" direction, the development of building materials and equipment manufacturing industry. "Five" includes high-tech (digital information technology, electro-hydraulic integration technology, intelligent technology, etc.), manufacturing green (green manufacturing technology, remanufacturing technology, etc.), demand customization (virtual manufacturing technology, manufacturing automation technology And so on), the development of clustering (economies of scale economies), integration of manufacturing services (the rising proportion of services in the value chain).
We aim at cultivating development (advanced equipment) and transforming and upgrading (traditional products) to achieve the transition from "internal demand investment" to "international competition", "scale expansion" to "innovation benefit".
Clearly develop the main tasks, improve the system and achieve innovation. These include: upgrading technological innovation systems, improving industrial supporting systems, developing manufacturing service systems, building industrial personnel training systems, and achieving three innovations in technology, commerce, and institutional mechanisms.
Full implementation of green manufacturing. Strengthen the research and development of advanced energy saving and environmental protection technologies, processes and equipment, speed up the green transformation and upgrading of the building materials and equipment manufacturing industry; actively promote low carbonization, recycling and intensification, and increase the efficiency of resource utilization; strengthen the green management of the product life cycle, and strive to build efficient , clean, low carbon, recycled green manufacturing system.
Deepen industrial international cooperation and speed up enterprises' going out. Actively participate in and promote international industrial cooperation, implement the major strategic plans such as the Silk Road Economic Belt and the 21st Century Maritime Silk Road, and promote the transformation and upgrading of building materials and equipment processing trade.
The development of building materials machinery and equipment is an important part of effectively promoting the landing of innovative green building materials; the establishment of a node between scientific research and development, mechanical equipment and product landing requires collaborative innovation on the industrial chain platform. Therefore, the establishment of China's Green Building Materials Industry Development Alliance's Advanced Equipment Manufacturing Industrialization Promotion Center coincides with the establishment of an advanced equipment manufacturing and service platform to assist in the advancement of China's industrial design level and equipment intelligence level. Landing provides support platforms to further promote the development of theoretical practice and market application of green building materials machinery and equipment industry in China.

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.
