According to China's current valve market, in addition to low-pressure valves have reached the level acceptable to the international market, high-pressure valves still rely on imports. In the situation that the macro economy continues to be optimistic, most of the production and sales indicators of the valve industry have maintained rapid growth, but due to the impact of price wars, the industry's sales revenue and profits have fallen sharply compared with last year. With the recovery of the world economy, the import and export of valve products in China has also increased, but the competition in the international valve market is also intensifying. Due to the large gap between high-end technology and large foreign manufacturers, product technology will become a bottleneck restricting the development of China's valve products in the future.
        Valves are indispensable for fluid control in petroleum, chemical, power station, long-distance pipelines, shipbuilding, nuclear industry, various low-temperature projects, aerospace and marine oil production. After years of development, the number of valve enterprises in China ranks worldwide*, and there are more than 6,000 valve companies of various sizes , of which 900 have an annual output value of more than 5 million yuan . From the product situation, China's valve industry has been able to produce more than a dozen major categories of products, such as gate valves, globe valves, ball valves, butterfly valves, safety valves , check valves, throttle valves, plug valves, pressure reducing valves , diaphragm valves, Traps, emergency shut-off valves, etc., Zui high use temperature reached 570 °C , Zui low is -196 °C , Zui high pressure is 600Mpa , Zui large diameter reaches 5350 mm. In addition, according to the relevant department statistics, China's annual valve market turnover of up to 500 billion yuan, of which more than 100 billion market was foreign occupation of the valve business. Although China's valve industry has developed vigorously after the reform and opening up, it has made great achievements. However, at present, there are still some problems in China's valve industry. For example, China's valve enterprises mainly focus on low-level, small-scale, and family-run enterprises. In the product, due to repeated investment, technology investment, and insufficient introduction, the leading products of China's valve enterprises are still low-quality mass products.
At present, various valves produced by Chinese enterprises generally have shortcomings such as leakage, internal leakage, low appearance quality, short life, inflexible operation, and unreliable valve electric devices and pneumatic devices. Some products are only equivalent to 80 in the last century. The international level at the beginning of the decade. Some valves required for high temperature and high pressure and key equipment still rely on imports. In addition, China's valve industry has a large gap between the industrial structure, the industrial chain of the valve industry, and the degree of specialization of the industry.
        The reason for the low quality of domestic valve products is that due to the rapid expansion of the market, the original state-owned valve enterprises have been shut down and transferred. The level of machinery industry is not high, and township enterprises (private enterprises) have developed rapidly. However, the starting point of township and village enterprises is low, the technical strength is very weak, the equipment is simple, and most of the products are imitative production, especially the low-pressure valves for water supply and drainage. The problem is serious.
In contrast to these problems, the future market prospects of China's valve industry are very broad. This is mainly for the benefit of:
1. Support from national policies. As the country accelerates the revitalization of the equipment manufacturing industry, the development of the general basic manufacturing industry will be further supported.
2. Strong demand in the valve product market. The state-owned economy continues to develop steadily. Investment in fixed assets has gradually expanded. In particular, the construction of several projects such as “ West-East Gas Transmission †, “ West-to-East Power Transmission †and “ South-to-North Water Transfer †requires a large number of valve products. In addition, China is facing the arrival of industrialization era, petrochemical industry and power sector. Larger valves, metallurgical departments, chemical industry and urban construction will increase the demand for valve products. For example, during the “ Eleventh Five-Year Plan†period, the total demand for valves for large and medium-sized coal-fired power plants in the “ Eleventh Five-Year Plan†period was: total valve demand of 153,000 tons, annual average demand of 30,600 tons; total valve demand of 3.96 billion yuan. The average annual demand is 792 million yuan.
3. With the entry of the WTO , the decline of international trade thresholds and the adjustment of product structure in developed countries, China is gradually becoming a large processing plant in the world, and the processing and production of valve products faces greater development space. -Sanjing Valve Technology Department provides
Nootropics powder or Nootropics, are a diverse group of cognitively enhancing compounds that are classified as lassi, plant, vitamin and fuel
I. Lassie drugs to promote wisdom
Rasciates are based on the compound piracetam and tend to work by enhancing the corpus callosum (the brain region that connects the two hemispheres), which can positively affect creativity and speech, acting as a glutamate or AMPA regulator (a subclass of neural receptors involved in learning and memory), brain circulation, brain metabolism, and more.
Lassi is the first class of psychotropic drugs that have been studied based on the naturally occurring amino acid Pyroglutamate (5-oxopyrrolidine-2-carboxylicacid). Most of them work by using glutamate receptors as agonists (compounds that mimic or enhance receptor activity) to enhance and enhance cognitive function. They are non-toxic, safe and do not have any addictive effects.
Piracetam, known chemically as 2-oxo-1-Pyrrolidineacetamide, is the most popular of the rascicidal drugs. Piracetam is known as nootropil in other countries. Piracetam is water soluble and is the best Nootropics studied. Piracetam is used in more than 100 countries and has been shown to improve articulation, memory, concentration, overall cognition and more.
Anisetan (anethacetam) is a fat-soluble form of piracetam, which is known in some countries as Ampamet. It's fat-soluble, and it's an ampakine drug (a class of compounds being developed by DARPA to create mind-enhancing super-soldiers).
NeuroPEPT, chemically known as n-phenylacetyl-L-Prolylglycineethylester, is a novel aminate glycine and a precursor of a naturally occurring peptide in the human brain. It is 1000 times more effective than piracetam and has high bioavailability. It is considered to be the third generation of lasciform nootropics.
2. Plant drugs promoting wisdom
These compounds are found in plants (or produced by plant compounds) to actively support cognitive or emotional health. Huperzine A (L-hupezine) is a common example of a plant nootropics. Huperzine A is an alkaloid extracted from the endemic Chinese plant Huperzine. Studies around the world have found that huperzine A can enhance memory, improve memory impairment, improve the efficiency of mental activities, senile memory decline and alzheimer's disease, adolescent learning disability and memory enhancement have significant improvement effect.
Three, vitamin drugs to promote wisdom
These compounds of vitamin stimulants have improved absorption, nootropic effects, and reduced side effects. They are made from vitamins or natural compounds found in the brain. They are very safe and non-toxic and have a long history of research and use around the world.
Enhanced versions of vitamins or related compounds are more effective than their counterparts. Such drugs include edibenquinone (associated with coenzyme Q), pyrimercaptan (associated with vitamin B-6), Picamillon (associated with GABA and vitamin B-3), Fenebute (associated with GABA), methylchlorophenol hydrochloride (associated with dimethylaminoethanol), and more.
Iv. Fuel drugs promoting wisdom
Fuel enhancers are compounds that act as precursors of major neurotransmitters and act as "fuel" for the brain. Such drugs include :ALC, phosphocholine, cyticoline, DMAE, chlorophenol hydrochloride ester, theanine, tyrosine, etc.
Citicoline is a source of choline that has been shown to improve memory and cognitive function. Citicoline is a water-soluble nootropic of the choline chemistry. CDP choline can be used to increase dopamine receptor density and is reasonably used to treat or contribute to ADHD. Acetylcholine is a neural receptor involved in memory processes and development in the brain. Citicoline helps to promote brain health by increasing acetylcholine synthesis and development in the brain and restoring the level of lecithin. It helps increase brain glucose metabolism and brain blood flow.
Phosphocholine is a phospholipid metabolite found concentrated in the membranes of neurons. It comes from lecithin, which is very well absorbed and crosses the blood-brain barrier. In the brain, phosphocholine supports brain function and learning processes by directly increasing acetylcholine synthesis and secretion. Phosphocholine acts as a precursor membrane phospholipid to support neuronal health and improve signal transmission
